Hello, I'm an ARK player and a web developer so I've some basic concepts in C++. I'd like to create a plugin to notify Discord's channel about player inactivity. I'm playing from MacOS using Nvidia Geforce Now. Do I need a Windows computer with ARK installed to develop my plugin ? Is there any updated resource to start ? (edited)

@Saxor I'm no professional, but if you have git and access to reliable C++ compiler then you are good to go. No need for Windows with ARK as long as you already have server on Windows. As for your second question it's hard to find something that is up to date. At least I had problems with it. But don't be afraid, if I sorted things out I'm more than sure you will as well.

any ideas where i can find tutorials to learn how to create a plugin, have very basic C++ knowledge but I have no idea where to start and there seems to be no tutorials out there. Anyone know of any?

Good the KalsCrossChat plugin works what is chat in the game and discord but the destruction notices are not working, I passed it to English and not anything else to do,? thanks. (edited)

How do i get the name (for example "Tek Foundation") from "APrimalStructure"?

APrimalStructure::DescriptiveNameField()

Thanks a lot

i tried to use "NameField" all the time :/ this works ty ❤️

NameField returns the BP name, like the name the blueprint file has. For example "Floor_Metal_C_1" (edited)

ya i saw that, but didnt found DescriptiveNameField() Btw this shows me the german words, prob just Server / game setting right?

Yes, it depends on server culture (edited)

Ok

Thanks alot for your quick help

No worries, feel free to ask anything else

@Browne there's a great google doc here: https://docs.google.com/document/d/1U4kRBevkLbXxcVMzKTmsjRKFkCEjtG46bfi5TdHNluQ/edit

I have it all set up however im not sure about the code itself, as I said my knowledge is very basic but its the code itself im struggling with

@Ashington

ah right, what are you trying to do?

basically i have used C++ before but never for anything like this, its way beyond what i know and i want to start learning i have looked everywhere for videos, turtorials and shit like that but i cant find anything and because im completely new to it im not even sure what exactly im looking for outside of searching ark plugin tutorials, so im looking for some resources to help me learn from basics up to creating my own plugin from scratch any help would be appretiated @Ashington

ah right, makes sense

12:26 AM

best source of information for me was the plugins out there - a lot of the functionality has been done there first so the interactions with the API can be sourced from there

12:27 AM

in terms of other management in memory/files etc that's just a standard programming problem which you'd have to tackle by designing your systems/writing tests etc

12:28 AM

I would say the first thing you should work out is what is possible using the API, and then work around that when designing the rest of your system, I did all the easy stuff first and found that it was difficult to do the actual interaction with the API (lesson learned)

12:28 AM

what are you trying to make as a plugin?

I have nothing in mind at the moment, will probably start by recreating existing plugins, easy ones

12:32 AM

work my way to harder ones

12:32 AM

then work on developing my own

12:33 AM

however my knowledge of C++ is so limited now that its probably betterr saying i know nothing

12:33 AM

because it has been a very long time since i have used it

12:33 AM

so for me its going to be a matter of re-learning the code

12:34 AM

then learning all the plugin sort of stuff which i dont even understand yet

Does anyone know how to get the FTribeAlliance by an AllianceID?

Try something like this

10:39 AM

        int alliance_id;
        AShooterPlayerState* State = static_cast<AShooterPlayerState*>(shooter_pc->PlayerStateField());
        FTribeAlliance* FTA = static_cast <FTribeAlliance*>(State->MyTribeDataField()->FindTribeAlliance(alliance_id));

10:39 AM

tho you need to get the shooter pc first

good, see I have 7 servers of the 6 the plugin load perfect and in one strip 11/08/20 06:44 [KalsCrossChat][info] ServerKey ? Ragnarok CreateProcess failed (5). which means that mistake thank you.

```cpp int alliance_id; AShooterPlayerState* State = static_cast<AShooterPlayerState*>(shooter_pc->PlayerStateField()); FTribeAlliance* FTA = static_cast <FTribeAlliance*>(State->MyTribeDataField()->FindTribeAlliance(alliance_id)); ```

@Foppa whats type is shooter_pc in that case? (edited)

3:23 PM

Because, the alliance i want, (where i got the Id from, i got nothing except the id :/

AShooterPlayerController* shooter_pc

8:09 PM

What do you want to have in return?

I have the Alliance Id and what the FTribeAlliance typ of that, from that i would take the members (tribes) of the alliance

found a way around it / found that i got something else i can work with

ark website access error

You don't have the pdb file installed so we can't know what crashes

so i need to put the pdb file of the plugin into the plugin folder?

If you want more detailed crash logs yes

ok, then gimme a few min

ok, weird, i copy pasted the code into a another plugin and now it doesnt crash?!! xD

5:16 PM

Ah ik why; this: Log::GetLog()->info("tribemembersInviter: {}", alliance.MembersTribeIDField().Num()); returns me this: -623357952 and cuz its negative it doesnt go into the next step

hello i cant compile...

11:27 AM

You are redefining an already existing struct

@Pelayori thanks! i did it!

do someone here know how to use ServerRequestRemoveAllianceMember(AllianceId, MemberId) i've tried saving the AllianceId after i force created one but it's changing all the time i leave manually

I think i tried that one, but if i remember correct, that didnt work, try using this ServerRequestRemoveAllianceMember_Implementation

thanks that's working. next thing is that i don't get the right ID directly. I have to request leaving once (and denie it with a hook) to get the correct Alliance ID how do you get the correct one?

10:18 PM

TArray<FTribeAlliance> allys = aPlState->MyTribeDataField()->TribeAlliancesField();
                            if (allys.Num() > 0) {
                                m_AllianceID = allys[0].AllianceIDField();
                            }

that's how i get it now which is the wrong one -.-

thats an issue i currently have, too. I am not sure, but i guess it doesnt get the FTribeAlliance correctly, sth there is broken i guess. Maybe someone else can help there

So alliances num is greater than zero but the actual FTribeAlliance is empty?

not really empty but "wrong" the Id isnt correct and i couldnt get the tribe id´s of the tribes in that alliance with MembersTribeIDField() (edited)

it's just little bit confusing how to retrive the correct data...

2:45 AM

But this works:

            AShooterPlayerState* state = static_cast<AShooterPlayerState*>(shooter_pc->PlayerStateField());
            if (state)
            {
                FTribeData* mytribedata = state->MyTribeDataField();
                
                int mytribe_id = state->TargetingTeamField();
                    Log::GetLog()->info("Checking For Tribe ID: {}", mytribe_id);

                int tribeMemberCount = mytribedata->MembersPlayerDataIDField().Num();
                    Log::GetLog()->info("My Member Count: {}", tribeMemberCount); // will return the count of players in your tribe

                if (tribeMemberCount > 0)
                {
                    int alliancesCount = mytribedata->TribeAlliancesField().Num();
                        Log::GetLog()->info("My Alliance Count: {}", alliancesCount); // Will return the count of how many alliances you have

                    int allyMemberCount = state->MyTribeDataField()->TribeAlliancesField().GetData()->MembersTribeIDField().Num();
                        Log::GetLog()->info("My Alliance Member Count: {}", allyMemberCount); // Will return the count of you and the members of the alliance

(edited)

is there a second part to this?

`struct FTribeAlliance { FString AllianceNameField; unsigned int AllianceIDField; TArray<FString> MembersTribeNameField; TArray<unsigned int> MembersTribeIDField; TArray<unsigned int> AdminsTribeIDField; }; /* struct FTribeAlliance { FString& AllianceNameField() { return GetNativePointerField<FString>(this, "FTribeAlliance.AllianceName"); } unsigned int& AllianceIDField() { return GetNativePointerField<unsigned int>(this, "FTribeAlliance.AllianceID"); } TArray<FString>& MembersTribeNameField() { return GetNativePointerField<TArray<FString>>(this, "FTribeAlliance.MembersTribeName"); } TArray<unsigned int>& MembersTribeIDField() { return GetNativePointerField<TArray<unsigned int>>(this, "FTribeAlliance.MembersTribeID"); } TArray<unsigned int>& AdminsTribeIDField() { return GetNativePointerField<TArray<unsigned int>>(this, "FTribeAlliance.AdminsTribeID"); } // Functions FString* GetDescriptiveString(FString* result) { return NativeCall<FString, FString>(this, "FTribeAlliance.GetDescriptiveString", result); } bool operator==(FTribeAlliance* Other) { return NativeCall<bool, FTribeAlliance*>(this, "FTribeAlliance.operator==", Other); } static UScriptStruct* StaticStruct() { return NativeCall<UScriptStruct*>(nullptr, "FTribeAlliance.StaticStruct"); } }; */` found it you have to replace the Struct in Tribe.h and then it works

(edited)

not rly tho

@ouzo1986 i get error if i use the struct like that, prob because it doesnt have the pointers

10:28 AM

can you maybe send me the code that worked for you?

@SorPlex that struct override and this: AShooterPlayerState* aPlState = static_cast<AShooterPlayerState*>(ps); TArray<FTribeAlliance> allys = aPlState->MyTribeDataField()->TribeAlliancesField(); if (allys.Num() > 0) m_AllianceID = allys[0].AllianceIDField; works fine for me. (edited)

and you just used that struc without any pointers or so?

10:46 AM

cuz i get an error without these pointers https://prnt.sc/vkn0m8

10:46 AM

@ouzo1986

yes i can. don't know why you can't

you also use the latest api right? xDD

was there an update in the last three days?

idk, but then i guess we have the same

11:01 AM

weird

I'm using Visual studio 2017 maybe that's the difference

im using 19, but would be weird, i redownloaded the api, ill test it again

seems to work now, updated the tribe.h and used the latest api

@staff after server starting my plugin does not respond to chat commands. If I reload plugin he start react to chat commands, but after time again not responding. how fix this problem? Plugin source - https://pastebin.com/WnWLW7LA

You shouldn't be using precompiled headers (edited)

Pelayori

You shouldn't be using precompiled headers (edited)

precompiled headers already disabled

You are including pch.h

6:34 PM

@Дивоглюк

yeah, thanks, I am testing your solution

Pelayori

You are including pch.h

after server started chat command not working

6:39 PM

after reloading plugins started response to chat command

By plugins.unload and plugins.load?

yeah

6:40 PM

but now plugin stopped response...

6:41 PM

I think after switched to other window by Alt-Tab?

Pelayori

By plugins.unload and plugins.load?

where can I find log messages generated by command Log::GetLog()->debug("Testing 123, please load the project for me ;)"); ? In console window they don't show

Then the plugin isn't loading/unloading

rcon console say "successfully unloaded\loaded plugin"

Oh well, ->debug might not show if it isn't compiled with debug

7:07 PM

try ->info

It detach my plugin by unknown reason...

oh... I searched this thread by 'detach' word and founded same problem) lost break in dll attach switch... deleted thread attach\detach cases and now it's work) thanks)

7:26 PM

there is another question... why melee, speed and max is 0?

okay GetBaseStatusValue return stats on 1 level dino I mean. How can I get stats of dino which will be used on mating?

does someone know how to create this type "FUniqueNetIdUInt64" as variable?

@ouzo1986 what do you want to use it on? I can't see a use for it. I believe it's also empty on ark code, I'd stay away from that (edited)

it's defined in GameMode: void AllowPlayerToJoinNoCheck(FUniqueNetIdUInt64* PlayerId) { NativeCall<void, FUniqueNetIdUInt64*>(this, "AShooterGameMode.AllowPlayerToJoinNoCheck", PlayerId); }

This is the definition of FUniqueNetIdInt64:

struct FUniqueNetIdUInt64 : FUniqueNetId
{
  unsigned __int64 UniqueNetId;
};

4:46 PM

Just declare a new funiquenetidUInt64, set its uniquenetid field to the id you want and pass a pointer with &your_variable

4:46 PM

@ouzo1986

thanks

Hello everyone! Using the Improved Commands source code, I was able to create a updated dino stats plugin (my first plugin). It is quite simple and only shows the dino the players own. I would like to be able to also show wild dino stats and I am having a hard time figuring out what is the wild dino team. I have set the setcheatplayer true and looking at few dinos, but it shows different teams ids. The wild teams ids, is it a range? Or should I go about another way to figure out if a dino is wild or not?

I believe it is 0

Then perhaps the team id in game is different from the dino->TargetingTeamField()!

In fact wild team id are between 0-10000 iirc (edited)

that would explain the many teams id i am looking at!

You also have APrimalDinoCharacter::BPIsTamed too, will return false on wild

Hello Pelayori! We meed again!

12:48 AM

thanks for the help once again!

No worries, I hang around here to help people

Hello, I am in need enlightenment. I am trying to make a list of all players spawn points to put on Safezones plugin, I did that on Extinction map and took a few hours, so naturally I thought I should make a plugin to record the position of the player death and safe it to a file or log. So far o got this:

void outPos(AShooterPlayerController* spc, FString* cmd, bool /**/)
{
    if (spc) {
        FVector pos = spc->DefaultActorLocationField();
        FString  aaa = pos.ToString();
        Log::GetLog()->info("Player position ({})", pos.ToString());
    }
}

When the player type /outPos it should output to the screen, but my knowledge of c++ is limited and I cant figure out how to get the FString to the Log::GetLog()->info function. I keep getting the error “Cannot format argument. To enable the use of ostream operator<< include fmt/ostream.h. Otherwise provide an overload of format_arg.” Any tips on how to proceed, is greatly appreciated

You must provide std::string or TCHAR array. you can pass aaa.ToString()

2:07 PM

And to get player location you might want to use spc->GetPlayerCharacter()->RootComponentField()->RelativeLocationField()

I cant believe I was putting pos.toString()

Pelayori

You must provide std::string or TCHAR array. you can pass aaa.ToString()

it worked. many thanks!

No worries

Hello again, when my plugin crashes, the server stops

6:29 PM

is there anyway to prevent that from happening ?

It’s hard to say without a closer look. At a basic level, that’s what exceptions are for, but the engine is complex and it’s possible handling a particular exception will still cause the server to crash. I would start by figuring out where it’s crashing at and you can isolate the issue. Something like trying to access a null pointer should resolve itself just fine within a try/catch; just be mindful of performance.

in this new update, everything is crashing, i was wandering if it would be possible prevent at least the plugins from crashing

6:49 PM

thanks!

ran out of memory allocating 1015808 bytes with alignment 0. I think that might be the problem

Sounds like it could be a memory leak. Something like this could happen when, for example, building a large dataset in which each item is a pointer in memory. Check to make sure you’re properly de-allocating your dynamic memory/variables.

that might be a problem. I don't know how!

7:09 PM

but i will figure out, i hope. Thanks for the help!

Start with a stack trace- it should popup a huge paragraph of text/code with line numbers (when the server crashes), you should be able to see within your plugin at what line it failed. I believe there are crash logs that you can access as well but not as familiar with that. I'm pretty oldschool and not as familiar with UE4 so I would suggest looking at how UE4 allocates/de-allocates memory and what class(es) you could use to help with that. But for good ol' C++ pointers/concepts, this youtuber is amazing (got me through my degree lol): https://www.youtube.com/watch?v=Fa6S8Pz924k

Hello

Is there a function in the Api that returns the current player count? (edited)

hmm i think i found it... int playerCount = ArkApi::GetApiUtils().GetShooterGameMode()->GetNumPlayers(); Will this return just the online player count or all players regardless of state?

It actually calls this function directly: int GetNumPlayers() { return NativeCall<int>(this, "AGameMode.GetNumPlayers"); } I would say yes, but best way to get answers is just to log it!

Yes, it returns the online player count

Good day guys, i'm new, where can I find the documentation?

DragoKing

Good day guys, i'm new, where can I find the documentation?

I think there is nothing really like that unfortunately

hey guys, is there something similar to javascript's Map().join() in c++?

6:44 AM

or am i better off just using JSON

6:45 AM

i'm trying to store all tribe members in a database, sorted by their tribe id, and my plan was to store the members by their character id in either one long string or a JSON object

I need to serialize character inventory data and send it to my webserver. But to understand the structure and understand without a description is difficult. If anyone can help, I will be grateful.

hi i downloaded the Ark Api Hook Generator but get a error could not create ssl/tls when opening the program can leave me a message of how to get it to work

yes me too. Probably because of the github ssl version update. You need api hook generator rebuild.

can i ask how do u rebuild the source code i am very new only messed with Jason configs

I opened and compiled the project in the visual studio 2019 community.

5:00 AM

There is nothing special.

ok i will give it a go thanx

hi i still get same message even after source code rebuild

7:06 AM

is it possible to somehow disable configs that turn off the lighting, shadows, leafage?

hiii (edited)

7:22 PM

i'm fully new to ark pc and linux servers

7:22 PM

is there a way i can setup multiple servers on 1 machine?

7:22 PM

but all use the same code?

that's how most, if not all, hosts do it for clusters... they just run them on separate ports (edited)

well i just figured out

8:01 PM

ARK api needs windows

8:01 PM

Rip my work for 2 days

lol

3:12 PM

just host it on windows, even the dedicated running more smooth on windows

I'm just starting on ArkAPI Development for Plugins. I'm thumbing through the calls in VisualStudio right now, but hoping someone can assist me faster here. What's the call to get a players exact location?

Think it is FVector Location = player->GetPlayerCharacter()->RootComponentField()->RelativeLocationField();

12:11 AM

But, how trying to figure out distance between 2 locations

there might be a util function for this, but there are offsets you have to apply to get the 100x100 coordinate values

Thanks @SublimeStyle

SolaoBajiuik

But, how trying to figure out distance between 2 locations

If you want to calculate the distance between 2 points, do something like: FMath::Abs((vector1 - vector2).Size())

8:05 AM

It will get you the distance in unreal units

I used FVector::Distance(location1, location2) to get the distance (edited)

Ohh didn't know that was a thing (edited)

Hello. When i use AActor* actor = primal_character->GetAimedActor and the player is dead ou on thw spawn screen it crashes the server

6:38 PM

is there anyway to check to prevent the crash?

check if primal_character is nullptr

6:40 PM

@Uaca

ok. im going to learn how to do~it, thank you!

just do if (primal_character) (edited)

7:19 PM

or if (primal_character != nullptr)

Hello, Can someone tell me how can I debug the code ? I mean, in other language, we can execute directly from the IDE or somewhere else and use breakpoints or other things like that to check objects etc...

Is there a safe way to save FVector to a json file and use it later, or would i need to setup some conversion process ?

You could just store X Y Z in a json array, and with that array initialize another FVector from constructor when needed

Is there technical documentation for the API that I can read through ?

10:56 PM

Trying to find how to split the player->GetPlayerCharacter()->RootComponentField()->RelativeLocationField() nowinto XYZ

not really however most functions in the game are from UE directly so most likely you can just google the function itself

K.. Thanks

Nvm that was too long lol

11:00 PM

You can do FVector.X for the components

Now to find out how to get it BACK to an fVector so I can use FVector::Distance

FVector(float x, float y, float z)

11:00 PM

That's the constructor

Noice.. Thanks

Well, one of them

Sorry about all the questions. I haven't done c++ in... almost a decade..

11:22 PM

I'm seeing that. Attempting to figure out why.

You need to add a reference to the function with &funcName

Is it possible to use cSharp instead of cpp ?

Apparently, I'm really rusty

Hi, sorry to bother. I am pretty new to this all but am looking at plugins for an ark server. My main problem is, I am using nitrado for hosting for now and I have no idea if arkapi even works with nitrado? I will look at the guides in a bit but not sure if they're applicable because I'm not self hosting

@Azarela nitrado doesn't support the API

2:01 PM

@SolaoBajiuik hard to say without seeing your implementation of your command

@WETBATMAN I am thinking it might be because I'm trying to do arguments. /mtape start /mtape stop (edited)

8:48 PM

and i'm not doing something right for the argument processing

how do you load the command ?

COMMANDS.AddConsoleCommand("mtape", ChatCommand); (edited)

8:59 PM

using the template he pushed up so COMMANDS is a macro for ArkApi::GetCommands()

that's a console command

9:16 PM

it would be cheat mtape

9:16 PM

in admin console

9:17 PM

if you want a chat command

9:17 PM

you need AddChatCommand

Ahhhh. K. Thanks :)

Hello, What is the best way to change the value of health / torpor / etc... from a character please ?

Thank you for your answer. I'm going to test that

void GivePlayerStat(AShooterCharacter* Char, EPrimalCharacterStatusValue::Type Stat, float AmountToGive)
{
    if (Char && Char->MyCharacterStatusComponentField() && AmountToGive > 0)
    {
        UPrimalCharacterStatusComponent* Comp = Char->MyCharacterStatusComponentField();

        float CurrentStat = Comp->BPGetCurrentStatusValue(Stat);
        float MaxStat = Comp->BPGetMaxStatusValue(Stat);

        float NewStat;
        if (CurrentStat + AmountToGive >= MaxStat)
            NewStat = MaxStat;
        else
            NewStat = CurrentStat + AmountToGive;

        Comp->BPDirectSetCurrentStatusValue(Stat, NewStat);
        Comp->ServerSyncReplicatedValues();
    }
}

Is there any documentation about the arkapi?

is there any example of how to use the permission plugin from my plugin?

Is there an Ark API plugin that can force same tribe across all servers?

Is there an Ark API plugin that can force same tribe across all servers?

Yes, it is called TribeEnforcer

Ah ty ❤️ @Pelayori

hello again!

4:47 PM

wild guess here, but would it be possible using plugins to make a player mount any dino?

Hello again, i would like to make a rest call

6:51 PM

i figure it out how to use the API::Requests::Get().CreateGetRequest

6:52 PM

but does not work from the Load function while the plugin is loading

6:54 PM

any tips on how to call a request as soon as the plugin finished load is very much appreciated

maybe, it would be the hook Hook_UEngine_IsInitialized ?

is there any other hook i can use from when the plug in is loaded from rcon? (edited)

I'm looking to make a plugin that will listen for when a player kills a boss dinosaur in the standard Ark arena or via open world spawn.

you can check if server is started like this

1:42 PM

so then you can do whatever you wanted to do on load

i see, thanks!

on the arkshop source code is has a few log for the sqlite database:

4:02 PM

Log::GetLog()->error("({} {}) Unexpected DB error {}", FILE, FUNCTION, exception.what());

4:02 PM

i cant find where this log is stored.

4:02 PM

does anyone have a clue or know where i can find this info?

ShooterGame\Binaries\Win64\logs

4:03 PM

Everything Log::GetLog() does will be in the API logs.

since it is not writing any messages, my code must be wrong before the sqlite function. Thanks!

quick question from a nooblet to ARK plugins; I've got an SQL server set up and finally connecting to plugins, but the default Permissions plugin is shooting me an error message that it can't add player (it's just me on my test server). Any likely causes?

Grab the latest beta version from Lethal, and it should work

hey guys, if I were to try to create my own plugins (not new to coding/basic c++ knowledge, but completely new to plugin stuff), where would I start? Honestly I am completely lost

is there some red line to follow somewhere? A guide, do's and don'ts? Some documentation I can't find? Thanks in advance!

take an existing project and start messing around. thats what i do lol

2:14 AM

there is a template out there somewhere too. i think one of these channels links it

Ok yes I have been trying to do that but some stuff isn't yet making sense to me

If you have an issue try reporting it and describe the issue as thoroughly as possible to Lethal in his discord. This is kind of the wrong forum.

Ah thanks

I will do that!

Or maybe update to a version that isn't 8 months old

2:31 PM

Also popcorning (old version/config may have popcorn listed for pvp) is only for raids which you need LethalORP for detection of the Raid CD. Running the latest version of most plugins is always advised.

Thanks for that. I am running both on new version but after I sent the message I was looking into the Lethal ORP and realised that due to people not actually using it, it wasn't proccing the raid detection (derp). So this is what i'm looking into atm

I completely understand this is a noob question, but I'm just really starting to look into plugin development out of interest

Trying to gain an understanding from open source work . . . For this example I'm looking into how the Suicide plugin works, and how its linked to Permissions I have read through the guide in #【🔶】ᴘʟᴜɢɪɴ-ᴛᴜᴛꜱ and my understanding was I would link it in Linker -> Additional Library Directories But no matter what I do, it cannot open source file "Permissions.h" Does anyone know why that might be? (edited)

(edited)

For linking permissions you need to include the permissions header, "ArkPermissions.h" (also add the header directory to C++ -> General and there additional include directories Then you will need to go to Linker-> Additional Library directories for including the directory of Permissions.lib And in your code #pragma comment(lib, "Permissions.lib")

12:14 AM

Permissions header name file has changed over time, if I recall correctly. That's why some plugins have Permissions.h, probably before Atlas came out

Yeah, I noticed the open source permissions had ArkPermissions so had messed about with re-naming a little both in the code and the actual file name But I will try the other things you mentioned too and see if that clears my error, thank you

Yeah, you need to include the header and link the lib with the pragma comment

12:16 AM

Same applies to base ark api, you need to include its header and pragma comment ArkApi.lib

12:17 AM

Otherwise you will end up with unresolved externals

You are a star, thank you Pelayori

Me again . . . with probably another daft question

So just trying to gain basic understanding of the process I should be following, I tried using WETBATMAN's Suicide plugin for the example below(also tried a couple others) and I keep getting this error when attempting to build, the issue doesn't seem to be with the plugin but with the api file, any ideas?

Someone has the most up-to-date shop with new functions, whoever I have I buy.

do you mean arkshop?

yes

He is talking about a ideas and suggestion that doesn't exist yet. There is some function in the Rework (Unstable version) But in the official ARK Shop these function is not yet applied, and he want to have a build with several functions. But there is no such thing yet, not even to "buy".

3:17 PM

Will update the Official ArkShop among other fixes with some soon, but not all those functions (edited)

someone asked me the same thing, i guess everyone wants some new functions on arkshop

Exactly, it is not just me, I have other friends who ask if there is any more updated shop, but there is only the official free, but there are some things missing in it that could go on later.

Well the way you are expecting it to be there is quite interesting

Yes, if I saw many things from those suggestions, I believe that shop will be even more complete.

Yeah, we will most likely see some more functions in the future

Let's wait

I'm trying to prevent players from leaving tribe once they join join. The code below only seems to prevent a player from being kicked (via the kick button), however they can still leave on their own. (via the leave tribe button) Is there anyway to keep 'em in the tribe forever?

c++
void  Hook_AShooterGameMode_RemovePlayerFromTribe(AShooterGameMode* _this, unsigned __int64 TribeID, unsigned __int64 PlayerDataID, bool bDontUpdatePlayerState)
{
    bool bCanNeverLeaveTribe = config["General"].value("LifetimeTribeMembership", false);
                                                                 
    if (bCanNeverLeaveTribe) {
        Log::GetLog()->info("CannotRemovePlayerFromTribe");
        return;
    }

    AShooterGameMode_RemovePlayerFromTribe_original(_this, TribeID, PlayerDataID, bDontUpdatePlayerState);
}

@jraServerAPI there is one way I can think

4:08 AM

with debugger

4:08 AM

when you leave tribe, your targeting team id is changed (edited)

4:09 AM

you can use Cheat Engine and find your targeting team address (I would log this value with a plugin) and attach the debugger

4:09 AM

and select break-point on write

4:10 AM

then when that changes, you will have the call stack at that instant and you can backtrace to see what function you need to hook.

4:10 AM

There's also a function from the player side to request to leave a tribe....so you could just hook that and block it

4:10 AM

both options should work.

void  Hook_AShooterPlayerState_ServerRequestLeaveTribe_Implementation(AShooterPlayerState* _this)
{
    AShooterPlayerState_ServerRequestLeaveTribe_Implementation_original(_this);
}

4:11 AM

Sadly it's a void

Foppa

void  Hook_AShooterPlayerState_ServerRequestLeaveTribe_Implementation(AShooterPlayerState* _this)
{
    AShooterPlayerState_ServerRequestLeaveTribe_Implementation_original(_this);
}

void doesn't cause a problem

4:20 AM

just return without calling the original

4:21 AM

void  Hook_AShooterPlayerState_ServerRequestLeaveTribe_Implementation(AShooterPlayerState* _this)
{
    return;
}

hmm I see there are two versions of the Hooks and I've been using the version without the "implementation" at the end... What is the difference? It looks like I may be doing it wrong

‍♂️

4:40 AM

(i noticed because you both posted Implementation responses lol) (edited)

‍♂️

4:58 AM

thank you guys

it's working now, using the Implementation hook instead. (edited)

4:58 AM

So what is the golden rule? Always use the implementation hook? or is it hit or miss?

Fake it until you make it?

2

12:55 PM

jraServerAPI

So what is the golden rule? Always use the implementation hook? or is it hit or miss?

hooks that have implementation in their name specify that that function has a client and server variant

1

1:25 PM

most of the time the hook that doesn't have implementation is the server one

1:25 PM

however in some cases it's reverse

1:32 PM

if you look at the function name it has ServerRequest, which means it gets called from the client first, then you can logically deduce that the function with Implementation is the one that gets called on the server and it's the function you need to hook

Thank you all!

Mariadb atm.

...I'm not the one who chose that one. Please tell me it's not incompatible.

5:19 PM

only 2 db's are supported.. sqlite requires nothing for you to do.. but Permissions will be map based only (edited)

5:19 PM

install mysql community server (free) on your machine and you can use mysql and have Permissions cluster wide (edited)

5:21 PM

you would need to setup mysql properly also..

Faaaaaaark

5:22 PM

That'd be it then

5:23 PM

A lot of other plugins are compatible with mariadb

But if permissions isn't, then fair enough

maria is mysql just not the official version

@Lethal oh, so it should be alright then?

Foppa uses MariaDB

MariaDB is to recommend imao

I have someplug in source code which is hard-coded with !player->bIsAdmin - preventing blocks running for non-admin users (who have permissions to run the cheat <command>), if I remove the references to these blocks does it mean that non-admins will be able to run these code blocks as a result if they have cheat.command permissions ?

Try casting szitem["Word"] to std::string

Thank you that worked.

you can also just do .get<std::string>()

3:36 PM

instead of casting

Well.. I've managed to fix the Mutes plugin so that it can run certain commands now without doing the admin check so it integrates with the admins permissions plugin, so I would say that its been a very successful day so far and I now have a DLL which works and I dont need to give my Moderators full admin permissions. Thank you all for your help.

hi guys, im new to plugin development and haven't used C++ in many years. I'm hoping to try to fix the ArkHomes plugin to not crash the server as it's currently doing. how might I send a console message? that would be logged in the ark servers loggs?

If you want API-style logs (those that print like [PluginName][info] This is my message), then use Log::GetLog()->info, but make sure to init it first. Init can be done on plugin's Load() function `Log::Get().Init("PluginName"); Other way is using the ark's integrated logs, that you can use from AShooterGameMode::PrintToServerGameLog or PrintToGameplayLog (both of these need -servergamelog in the server launch args)

ok thanks, I saw another mention of the Log:: inside the ArkHomes plugin so I assumed that was the way to do it. its loading now so we see what happens

Does anyone know of a simple method I can get all tribes and last login dates for that tribe - so I can export it to the logs?

if you know the tribeID you can use GetOrLoadTribeData

2:05 PM

FTribeData* CreatedTribeData = static_cast<FTribeData*>(FMemory::Malloc(0x200));
            RtlSecureZeroMemory(CreatedTribeData, 0x200);
            ArkApi::GetApiUtils().GetShooterGameMode()->GetOrLoadTribeData(CreatedTribeID, CreatedTribeData);
            FMemory::Free(CreatedTribeData);

2:05 PM

replace CreatedTribeID with the tribe id of your choice

2:06 PM

cache the results, because this function leaks memory, don't call it alot

2:08 PM

and ofc call FMemory::Free after you're extracted the info you need not immediately after GetOrLoadTribeData

Thank you that makes sense, I'm assuming that you can only get the online tribeIds rather than find all tribeIDs with a plugin?

there should be a way to get all tribes online and offline

WETBATMAN

cache the results, because this function leaks memory, don't call it alot

You know what, I might attach Valgrind or something to the API

I want to know why that function leaks memory and if it can hotpatched to NOT leak

@Lethal @WETBATMAN I think I know what the memory leak for that function is

10:20 AM

it's a different function it calls when the data isn't already loaded.

10:20 AM

this v233 pointer is constructed but is never free'ed before returning

a similar function that reads user data returns the pointer created from NewObject while LoadTribeData only returns true/false since you pass in a buffer.

Ya, that is part of the code where it reads the physical tribe data file from disk.

Lethal

Ya, that is part of the code where it reads the physical tribe data file from disk.

I sent my findings to Wildcard so hopefully they’ll add a free

4:37 PM

The heap object is used for the deserialization but they only copy a field from that into the passed in buffer

4:37 PM

The object can safety be deleted after you get a copy of this buffer

Ah, nice. I'd be interested if they actually confirm they fix it back to you.

well whatever you type into the console is supposed to be a console command and i don't think it's gonna be sent to the server unless it's prefixed with cheat

WETBATMAN

Log::GetLog()->Info()

doesnt appear to be printing anything into the console

Atomicskullz

doesnt appear to be printing anything into the console

Did you Init the log? You need to add Log::Get().Init("PluginName"); at the plugin load function

yep

could someone tell me which one I should use if im inserting, removing, and accessing elements frequently? A or B?

c++

// A
typedef unordered_map<string, int> Sub; // possibly 30+ entries
typedef unordered_map<string, Sub> Main; // possibly 30 or fewer


// B
typedef vector<tuple<string, int>> Sub; // possibly 30+ entries
typedef unordered_map<string, Sub> Main; // possibly 30 or fewer

(edited)

would this be the correct way to add experience when given an AShooterCharacter* ?

10:42 PM

// m_pInstance is AShooterCharacter*
auto ctrl = m_pInstance->GetCharacterController();
auto shooter_ctrl = static_cast<AShooterPlayerController*>(ctrl);

shooter_ctrl->AddExperience(100, false, false);

10:44 PM

and how do i get the total experience a player has?

That looks like it will work, although you may want to have the last argument true, otherwise I believe it will share the experience with the tribe mates in the area if you leave it false. (edited)

Atomicskullz

would this be the correct way to add experience when given an AShooterCharacter* ?

I would use the API, or take a look at the function: AShooterPlayerController* aspc = ArkApi::GetApiUtils().FindControllerFromCharacter(character); (edited)

Foppa

I would use the API, or take a look at the function: AShooterPlayerController* aspc = ArkApi::GetApiUtils().FindControllerFromCharacter(character); (edited)

that function takes O(n) time

        AShooterPlayerController* FindControllerFromCharacter(AShooterCharacter* character) const
        {
            AShooterPlayerController* result = nullptr;

            const auto& player_controllers = GetWorld()->PlayerControllerListField();
            for (TWeakObjectPtr<APlayerController> player_controller : player_controllers)
            {
                auto* shooter_pc = static_cast<AShooterPlayerController*>(player_controller.Get());

                if (shooter_pc->GetPlayerCharacter() == character)
                {
                    result = shooter_pc;
                    break;
                }
            }

            return result;
        }

while that field should always have the player controller

10:13 AM

honestly we should probably update FindControllerFromCharacter to use the field if the field is non-null

Yeah

There's a few other issues in the helpers class

10:17 AM

FindControllerFromCharacter has null checks but GetSteamName does not for example

10:17 AM

nothing too horrible but def. inconsistent

10:17 AM

maybe this weekend I can spend some time to update the header

@substitute I had updated it, but from tests it seemed to be unreliable

11:39 AM

AShooterPlayerController* FindControllerFromCharacter(AShooterCharacter* character) const
        {
            if (character)
            {
                AShooterPlayerController* result = (character->GetOwnerController() != nullptr) ? 
                    static_cast<AShooterPlayerController*>(character->GetOwnerController()) 
                    :
                    static_cast<AShooterPlayerController*>(character->GetInstigatorController());

                return result;
            }
            
            return nullptr;
        }

11:40 AM

Not sure if you have any idea on how to improve it, because it was crashing at GetOwnerController

Pelayori

Not sure if you have any idea on how to improve it, because it was crashing at GetOwnerController

had the very same issue actually

12:59 PM

GetOwnerController was working perfectly fine on my end but it crashed on someone else's server

^^

even tried the exact same server config on both machines

12:59 PM

mine always worked, the other always crashed idk why

I had pushed a PR with those changes but ended up closing it because of that unreliability to reproduce the crash

Pelayori

I had pushed a PR with those changes but ended up closing it because of that unreliability to reproduce the crash

Did we ever get the specific crash logs?

3:55 PM

I’m curious why that would happen

No, but I can dig up for them

Thanks

3:55 PM

Maybe it’s something with a mod

3:55 PM

Very curious

3:56 PM

That's the one I remember having

3:56 PM

It was from when I compiled permissions with that function I sent

3:57 PM

At the bottom when equipping an item, at the front one right after startup

3:57 PM

Quite old though

3:58 PM

@substitute

Hm, yeah. Only thing I can think of off the top of my head is a race condition

It had null check, but I can also remember some things I worked on where even though null check they were still passing and failing on getting something of said pointer

4:01 PM

So they weren't really null

Yo

10:53 PM

Super noob man here

10:53 PM

I wanna make it so that Argy's get the imprint speed buff like other dinos do

10:53 PM

This doable?

The compress2 error is fixed with DumpAll i'm pretty sure which is why we need to just release the API with it enabled. I have been providing it that way in my early releases on my discord.

The compress2 error is fixed with DumpAll i'm pretty sure which is why we need to just release the API with it enabled. I have been providing it that way in my early releases on my discord.

It’s like 3 extra seconds of start up for worlds more compatibility

4:54 AM

Dump all should be default

4:55 AM

(3 seconds of start up is nothing when the server takes 5 minutes to boot clowntrophy

)

Lethal

The compress2 error is fixed with DumpAll i'm pretty sure which is why we need to just release the API with it enabled. I have been providing it that way in my early releases on my discord.

Ah great then. I guess APawn is not dumped by default then?

Pelayori

Ah great then. I guess APawn is not dumped by default then?

Ya, it's not in the default config.json.

That would explain everything. Thank you very much. By that time I didn't have dumpall true. However I'll still ship pdbconfig files since even though official api will have it I'm sure someone will skip the new config.json

actually API does dump APawn without DumpAll

2:21 PM

this is because when you specify a class/struct for pdbreader it dumps it and it's children

2:21 PM

APawn is child of AActor (which is dumped by default)

But then why would it crash without dump all and then work with it enabled

        typedef std::tuple<const char*, int> CCEntry_t;
        typedef std::unique_ptr<CCEntry_t> CCEntryptr_t;
        typedef std::vector<CCEntryptr_t> CCVec_t; // contains the console commands along with their luareg index

(edited)

3:16 PM

is this too complex for what I need to be done?

3:16 PM

i was thinking of doing an unordered_map with const char* as key and int as value

3:17 PM

but i was thinking of performance

3:17 PM

and the problem is that const char* isnt hashable, therefore it wont work correctly in a map (edited)

3:18 PM

so im unsure what to use (edited)

Atomicskullz

and the problem is that const char* isnt hashable, therefore it wont work correctly in a map (edited)

Std string

yes ik

7:17 PM

but the performance

Standard library strings are absolutely hashable (edited)

i know that...

7:55 PM

im asking if its feasible for this

7:56 PM

compared to using find_if with strcmp if it were a vector (edited)

Can anyone explain the difference between static_cast and dynamic_cast? Did research but i cant wrap my head around it. All i know is that static_cast occurs during compile time, while dynamic_cast occurs during runtime. I dont really understand

Can't really say myself, but I'd guess static cast is on compile time, faster and used for pointers while dynamic is at runtime, slower and for references?

11:39 AM

I mostly use either static/reinterpret casts

How do i add new blueprints using the API?

If anyone could just tell me a function name

2:58 PM

I could just look it up on github and find examples

you mean like add an additional item?

Yeah

3:10 PM

Like making my own

i don't think this is doable with a plugin, since it would have to be replicated to the client

Damn thats right

3:12 PM

Didnt think of that

Any1 know if there’s a macro for determining if the server is using ark or atlas?

hm?

12:24 PM

you have to compile with AtlasAPI for atlas and ArkApi for ark

is there anyway to manipulate weapon damage or other stats?

Atomicskullz

yes, check out https://discord.com/channels/513432877904691202/513822106639794196/701008221632069633

uh that doesnt really answer the question

5:38 PM

oh wait wtf

5:38 PM

nvm

5:38 PM

scroll was bugged

5:38 PM

thanks

Does the EngramBlueprintClassesField() function in Gamemode.h actually contain all the current engram entries available?

Yes

12:27 AM

Well, wait

12:28 AM

I know EngramBlueprints from UPrimalGameData does have all engrams

Ah ok, interesting. Which ever one is best performing for a simple iteration that retrieves the names and levels of them ill use (edited)

12:46 AM

Will have to do some experimenting

Atomicskullz

Will have to do some experimenting

auto Singleton = (UPrimalGlobals*)Globals::GEngine()()->GameSingletonField();
auto GameData = Singleton->PrimalGameDataOverrideField() ? Singleton->PrimalGameDataOverrideField() : Singleton->PrimalGameDataField();
auto EngramClasses = GameData->EngramBlueprintEntriesField();

(edited)

Ok cool, thanks

is there anyway to get the stored weapons? like a list of them with their damages and stuff

or just a list of all the items with their stats. because im not sure if i can get the template damages from a UPrimalEngramEntry (edited)

yeah unsure. i found out a way but it looks a little dirty

2:49 PM

auto Singleton = (UPrimalGlobals*)Globals::GEngine()()->GameSingletonField();
    auto GameData = Singleton->PrimalGameDataOverrideField() ? Singleton->PrimalGameDataOverrideField() : Singleton->PrimalGameDataField();
    auto EngramClasses = GameData->EngramBlueprintEntriesField();

    for (auto x : EngramClasses)
    {
        auto sub = x->BluePrintEntryField().uClass->GetDefaultObject();
        auto casted = static_cast<UPrimalItem*>(sub);

        float damage = casted->GetWeaponTemplateMeleeDamageAmount();
    }

2:49 PM

mind the var names, just tempoary

That's probably one of the best ways if you need all craftable weapons

2:53 PM

There is no such singleton with all weapons

Are there any very basic plugins I could have a look at as an example to get an understanding of what plug-in development is like?

3:19 PM

I'm very new to C++

Sorry if this sounds blunt, but you shouldn’t really be doing this kind of stuff if you’re “very new.” There’s a lot of stuff you have to learn in order to make efficient code.

I disagree. If the person has previous experience in other languages, picking up C++ is usually straight forward.

C++ is a totally different beast wtf are you saying waitwhat

Atomicskullz

I had no issues picking up C++

Cool

If you understand the concepts, it’s a straight forward language.

People who say they are “very new” usually tend to not understand it, otherwise they wouldnt say it

9:38 PM

I see it all the time in another server (edited)

9:41 PM

I dont mind if someone is new to c++, but trying to explain something to someone like that is uh (edited)

9:42 PM

idk its prolly just me and my past experiences

so uh why am i getting an error when using FString as a key for a map?

1:22 AM

struct EngramEntry
{
    FString name;
    TSubclassOf<UPrimalItem>* engram;
    int level{};
};

extern TMap<FString, EngramEntry> g_EngramMap;

1:22 AM

could have sworn FString was hashable

1:22 AM

on compile it throws "TMap must have a hashable KeyType unless a custom key func is provided."

Atomicskullz

could have sworn FString was hashable

Easy work around, use the c string value

7:07 AM

There’s a function to get the underlying string from FString

Ok thanks

yeah, but thing is that FString is the key used for some of the functions/fields in the API, like in AShooterGamemode Struct (edited)

2:27 PM

TMap<FString, FString, FDefaultSetAllocator, TDefaultMapKeyFuncs<FString, FString, 0> >

2:28 PM

yet the compiler doesnt complain when it goes through that

2:28 PM

only thing i can try is setting the KeyFuncs

2:28 PM

but by default it should have worked

found something that may work

2:37 PM

struct FMyStruct
{
    // String which identifies our key
    FString UniqueID;
 
    // Some state which doesn't affect struct identity

2:38 PM

but still, i dont know why the compiler doesnt complain about maps using fstring in the api

Just use the TMap

4:01 PM

TMap is the UE4 map type

Yes thats what ive been using

struct FStringStruct
{
    // String which identifies our key
    FString UniqueID;

    // Some state which doesn't affect struct identity
    float SomeFloat;

    explicit FStringStruct(float InFloat)
        :UniqueID(FGuid::NewGuid().ToString())
        , SomeFloat(InFloat)
    {
    }
};

5:41 PM

it says NewGuid() is missing (edited)

5:41 PM

any alternative?

ya even Crc::MemCrc32 isnt there

10:46 PM

so its impossible to make a hashable struct

Atomicskullz

ya even Crc::MemCrc32 isnt there

You can always add the missing references if any are missing

ye thats what im doing rn

In IDA you can find CRC Mem32

11:21 PM

and then construct a header similar to the FMemory header

oh im just using the UE4 source lol

That will cause you a lot of problems

all im doing is getting the MemCrc32 function

11:22 PM

which has nothing to do with the game

11:22 PM

if you know what i mean

Yes, don't reference it from the UE4 source, reference the one built into the game.

its poco stuff

11:22 PM

yeah but i dont know how to ida pro lol

You just open the game in IDA pro

11:22 PM

there it will have a function list

11:22 PM

you can ctrl+f

11:23 PM

https://github.com/Michidu/ARK-Server-API/blob/f5f0fedcb9d71d0e277a8f9ca659c3d9568205b5/version/Core/Public/API/UE/HAL/UnrealMemory.h#L105

11:23 PM

example with FMemory

11:23 PM

it uses the function pointer from the game via the PDB

11:24 PM

@Atomicskullz anyways, if you are just wanting to store a map based on the value of the string

11:24 PM

map<std::string, FString>

11:25 PM

if you want the FString to also map to a complex object just make a wrapping struct

struct MyStruct
{
  FString a;
  void* whateveryouwant;
}

map<std::string, MyStruct> myMap

so i shouldnt use TMap then?

11:29 PM

Crc.h and Crc.cpp fit into the project perfectly

11:29 PM

all the required headers were already there

11:29 PM

i might need to make a new fork

so i need some help with when I should use dynamic_cast. Previously, I always used static_cast when downcasting, and according to research I conducted its more safer than dynamic_cast. I know that dynamic_cast occurs during run-time, but I dont know the significance behind it.

So im really new to this stuff, anyone know how i would go about placing lets say a metal foundation with the plugin?

Axenari

So im really new to this stuff, anyone know how i would go about placing lets say a metal foundation with the plugin?

You would need to load the BP path of the foundation, to get the UClass* of the foundation. to load it use UVictoryCore::BPLoadClass() Then you can use ArkApi::GetApiUtils().GetWorld()->SpawnActor() (edited)

xD your not the only one

Hey! Is there a place that has a collection of premade JSON files I can build off of for my servers for the Shop,Currency, and Kits plugin?

️

Hey, I am getting a ton of errors similiar to this:

version\Core\Public\API\UE\Containers\../Windows/MicrosoftPlatformString.h(24): error C2664: 'errno_t strcpy_s(char *,rsize_t,const char *)': cannot convert argument 1 from 'WIDECHAR *' to 'char *'

C:\Program Files (x86)\Windows Kits\10\include\10.0.19041.0\ucrt\string.h(32): note: see declaration of 'strcpy_s'

It seems UE/BasicTypes is including headers that, at least on my system, contradicts each other. Has anyone encountered this before?

12:01 AM

Oh, yeah, I am using CMake in CLion; not sure if anyone has managed to get that working? Slowly warming up to the idea of welcoming VS back on my system.

(edited)

Got it all figured out.

Has anyone stumbled across a variable that can tell if a player is controlling a Noglin? For reference, I currently use OwnProx's Teleport Plugin and allow players to use the /tpr and /tpa functions. However, the plugin doesn't (and had no reason to until now) check to see if the player is controlling a Noglin and will actually put the player who is teleporting where the Noglin is and not the actual location of the player. So, my basic idea was to prevent accepting a request if the player is controlling a Noglin. Hopefully that all makes sense.

Probably the controller of said noglin is now a player controller

Yeah, that is my assumption based on the way it is functioning.

Im trying to give an item to a player by command, i need this item to have a custom name. ive not been able to find how id do something like that tho. Last try was this:

item->DescriptiveNameBaseField() = "Trophy";
item->UpdatedItem(false);
Log::GetLog()->warn(item->DescriptiveNameBaseField().ToString());
AttackerShooterController->GetPlayerInventory()->AddItemObject(item);

This gives the actual item i want to, the log shows the name ive given it but the client doesnt see it

And won't see it either

9:05 PM

Name is not replicated

So theres no way to do this?

No

9:07 PM

Not sure if there's anything like custom item name that is replicated

9:07 PM

but I know you can change description (edited)

Maybe that would work then, how would i do that?

Tbf, I don't remember

9:08 PM

Custom Item description I believe

9:08 PM

then multicast it

9:08 PM

and replicate

oh god ive got no clue how to do that xD

or replicate at the end might not be necessary (edited)

multicasting is smthing ive never done (or know what it means)

multicasting means sending the updated value of a replicated variable over to clients when multicasted

9:10 PM

you do actor->MulticastProperty(FName(L"varNameWithoutField", EFindName::FName_Add, false));

Cool ty!

I don't 100% remember it was that way though

9:12 PM

Just keep in mind multicasting just works for variables that are replicated (wouldn't work for example with descriptive item name)

While im asking.. ive got 1 more issue. I want to use a hook when an item gets taken from an inventory (not hard at all) but heres the catch, i want to see who takes it and from where so i can check if their from the same tribe

9:13 PM

Makes sense, ty!

Pelayori

Not sure if there's anything like custom item name that is replicated

I think you can do a custom name

On items?

Im listening xD

Yes, issue has been identified and a new patch is soon to arrive

Anyone know how i would delete an item? Tried this but first makes me crash and second times out the player and freezes real bad item->BeginDestroy(); item->RemoveItemFromInventory(true, true); (edited)

Remove it from the inventory reference

8:18 PM

UPrimalInventoryComponent::RemoveItem

So i wont be able to remove the item from any inventory by deleting an item?

No, you need to loop trough every inventory and delete it, or loop trough all item references if you have a list already, get owner inventory and then remove item

Alright! That makes me wonder something. Ill give a quick explenaition, im trying to create a custom spoil system

8:22 PM

If they drop the item i think that will bypass right?

Most likely

Mhh, ive been told every class has a destroy function that will get rid of it entirely

8:24 PM

its not the case for UPrimalItem i guess?

8:24 PM

Sorry if im being dumb, trying to figure out whats my best bet for deleting this item

There is DestroyAll command, but it does not work for child classes s you'd need to loop each dropped item class either way

Okay let me ask different, if you were to make a spoil system, You already have a working timer, and a pointer to the actual item How would you make the item get removed?

Axenari

Okay let me ask different, if you were to make a spoil system, You already have a working timer, and a pointer to the actual item How would you make the item get removed?

item->OwnerInventoryField()->RemoveItem(&item->ItemIDField(), false, false, true, true);

epic! i didnt know you could reverse get an inv from an item

8:35 PM

ty

Yeah, items hold a reference to the owner inventory

8:36 PM

And from the owner inventory, you could get OwnerField, that can be character, structure, etc...

Very interesting!

8:42 PM

im still struggling with me timing out the entire time because of my plugin first before i can test xD

oof! that crashed my server

8:53 PM

(yes i copied the plugin of WetBatman to create my private plugin)

Might be worth to check if the inventory is valid

Its literally my own inventory tho

8:57 PM

Ill add it for just future cases

8:57 PM

Its a spawned in item, unmoved and in my personal inventory

@Axenari Is it for resources that could stack more than 1 actually?

9:13 PM

If that's the case you can use this

9:13 PM

item->OwnerInventoryField()->IncrementItemTemplateQuantity(item->ClassField(), -1, true, false, nullptr, nullptr, false, false, false, false, true, false, true);

It wont stack

9:21 PM

Its a survivers trophy w custom name

Hmm, then don't use the increment function, it will choose any item of that class and remove

Aha

Pelayori

item->OwnerInventoryField()->RemoveItem(&item->ItemIDField(), false, false, true, true);

try this but instead print the ids from itemidfield

9:22 PM

to see what it outputs (edited)

Willdo when i get home

9:22 PM

Tf

9:22 PM

Ty*

Axenari

Ty*

Either way, the removeItem just calls the UPrimalItem::RemoveItemFromInventory though

Problem seems to be finding the item

9:42 PM

Oddly

How are you storing the pointer? (edited)

UPrimalItem* alphatrophyitem;

10:36 PM

and then when i want to spawn it i do this

10:36 PM

FCustomItemData cdata;
                    cdata.CustomDataName = FName("Alpha Trophy1", EFindName::FNAME_Add);
                    alphatrophyitem->CustomItemNameField() = L"Alpha Trophy";
                    alphatrophyitem->SetCustomItemData(&cdata);
                    alphatrophyitem->UpdatedItem(false);
                    static_cast<APrimalStructureItemContainer*>(Stand)->MyInventoryComponentField()->AddItemObject(alphatrophyitem);

10:36 PM

theres only 1 instance of the item at a time so i think i dont need a fancy system

Hey @substitute , did you ever hear back from WC about this? Do you know if they have fixed it?

Does anyone know how i can ensure a structure stays unlocked?

ArkApi::Tools::ConvertToWideStr is deprecated? Is there a replacement?

@Uaca ArkApi::Tools::Utf8Decode(config["Messages"].value(str, "No message")).c_str());

@Pelayori any chance you know how to lock and unlock a structure

7:58 PM

Tried to check w ida but i cant find it (kinda dont know how to use it fully either tbh)

Axenari

Tried to check w ida but i cant find it (kinda dont know how to use it fully either tbh)

Do you mean pin code or engram?

Literally the lock and unlock on lets say a storage box

Axenari

Literally the lock and unlock on lets say a storage box

you need to set the pin code

10:20 AM

to unlock simply set the pin code to nothing

oh wow, that easy? xD testing it soon

Can anyone help me with attaching a debugger? it either crashes the server or freezes the server, no clue what im doing wrong

@Axenari to unlock just set bUnlocked() to false/true, bIsPinCoded() to true/false and if setting pin lock set the pin code (think there's a function for it)

Thanks! just found that out

Hi, does anybody know where the Survival Quotient (killed bosses) is stored? I looked using ark-tools into .arkprofile and .ark save and didn't find anything

Fenix

@Uaca ArkApi::Tools::Utf8Decode(config["Messages"].value(str, "No message")).c_str());

ThankS!

Does anyone know if theres a hook for items that spoil? or how to detect it via another hook?

Axenari

Does anyone know if theres a hook for items that spoil? or how to detect it via another hook?

Maybe not directly, but you could look at UPrimalItem_GetSpoilingTime and when time is 0 or 1, (small time), you could trigger your logic

@Pelayori Do you know a hook i should use for checking when any item gets destroyed? Ive got this item of which there at any point should only be 1. this item spoils too. So im thinking how i should track this item dissapearing. and ive got no clue

7:02 PM

Right now im trying the hook BeginDestroy However this triggers at really weird moments (My IDA is fucked too, cant check there)

@Axenari There is a hook I found in the Server API hook Creator App. I'm not sure if it actually works though.

c++
DECLARE_HOOK(UPrimalItem_BeginDestroy, void, UPrimalItem*);

void  Hook_UPrimalItem_BeginDestroy(UPrimalItem* _this)
{
    UPrimalItem_BeginDestroy_original(_this);
}

ArkApi::GetHooks().SetHook("UPrimalItem.BeginDestroy", &Hook_UPrimalItem_BeginDestroy, &UPrimalItem_BeginDestroy_original);

ArkApi::GetHooks().DisableHook("UPrimalItem.BeginDestroy", &Hook_UPrimalItem_BeginDestroy);

(edited)

Thats the thing @DizzyDwarf i use this, but it fires at random situations where nothing happens to the item

Axenari

Thats the thing @DizzyDwarf i use this, but it fires at random situations where nothing happens to the item

This is when the engine destroys the actor

8:19 PM

Not when the item breaks

It doesnt seem to be the case tho

9:18 PM

it triggers when i spawn in an item

and it somehow triggers multiple times without even doing anything

Axenari

It doesnt seem to be the case tho

https://docs.unrealengine.com/4.26/en-US/API/Runtime/Engine/GameFramework/AActor/BeginDestroy/

AActor::BeginDestroy

Called before destroying the object.

10:07 PM

Destroy in this instance means to clean up a garbage object from memory.

10:09 PM

An object can be moved around in memory to different instances as required, which would leave the previous instance as garbage. One example is dropping an item from your inventory. The item no longer exists and is instead the dropped item instance. Now whether or not WC moves the object reference or creates a new one on the dropped item, I don’t know, this is just an example where it could do a copy construct

Right so that doesnt really mean the item is gone..

Correct

Maybe i should take it another way, as theres always only 1 of the items i have a pointer to it. Is there a way to see if the item is still in the server?

Check if pointer is nullptr

2:34 PM

You might want to use weak object ptrs when storing them somewhere where the pointer persists. TWeakObjectPtr<UPrimalItem> item_ptr = GetWeakReference(item);

2:35 PM

That will store the pointer safely and retrieve it if it's still valid, if not then it will return a plain nullptr

2:35 PM

To get the pointer back you can do item_ptr.Get()

2:36 PM

Anyways let me search deeper for spoil

To check if its still a thing if(item_ptr != nullptr)

2:36 PM

Right?

if (item_ptr.Get() != nullptr)

Spoil isnt needed per se, i just need to know if its still there

Well, if the pointer is valid means the item is somewhere in the world

2:37 PM

Might be on a dropped item, might be on an inventory, etc...

I first took it with the approach to check when it despawns and when it spoils, thats why i wanted to know a spoil hook

2:37 PM

The only info i need is if its anywhere or nowhere so i know enough :)

2:39 PM

One thing i am still struggling with however is spawning in a structure, i got a code from someone where i can spawn in an actor. But i can walk thru it, it doesnt have an owner and it doesnt have an inventory. I would check IDA but its literally broken for me

How are you spawning the actor?

Let me find it

2:41 PM

    inline AActor* BPSpawnActor(UWorld* uworld, FString blueprint, FVector* location, FRotator* rotation, bool do_begin_play)
    {
        //auto* world = ArkApi::GetApiUtils().GetWorld();
        if (!uworld) {
            return nullptr;
        }

        UClass* object_class = UVictoryCore::BPLoadClass(&blueprint);
        if (!object_class) {
            return nullptr;
        }

        FActorSpawnParameters new_actor_spawn_params;
        new_actor_spawn_params.bDeferBeginPlay = true;

        auto* actor = uworld->SpawnActor(object_class, location, rotation, &new_actor_spawn_params);
        if (actor) {
            if (do_begin_play) {
                actor->BeginPlay();
                actor->ForceReplicateNow(false, false);
            }

            return actor;
        }

        return nullptr;
    }
    
    auto* world       = ArkApi::GetApiUtils().GetWorld();
    auto  character   = player_controller->GetPlayerCharacter();
    auto  location    = character->RootComponentField()->RelativeLocationField();
    FString blueprint = "Blueprint'/Game/PrimalEarth/Structures/StorageBox_Small.StorageBox_Small'";
    
    auto* actor = BPSpawnActor(uworld, blueprint, &location,

2:42 PM

Accidentally removed too much from the end part here, the last line is normally intact

2:43 PM

I know how to set the health, but not to add an inventory etc

        UWorld* world = ArkApi::GetApiUtils().GetWorld();
        FString tek_path = FString("Blueprint'/Game/PrimalEarth/Structures/StorageBox_TekShield.StorageBox_TekShield'");

        UClass* structure_class = UVictoryCore::BPLoadClass(&tek_path);
        if (!structure_class) 
            Log::GetLog()->critical("There was an error while processing new structures");

        AActor* new_actor = world->SpawnActor(structure_class, &loc, &rot, &params);
        if (new_actor && new_actor->IsA(APrimalStructureItemContainer::GetPrivateStaticClass()))

2:45 PM

This works for me

2:46 PM

loc, rot are on another place outside there, and params is just empty FActorSpawnParameters

Oh damn nice

7:43 PM

will test that very soon

@Pelayori I tried the TWeakObjectPtr thing, the weird thing is it comes thru as a nullpointer at random times. Whenever i throw it on the ground like 15 seconds before it spoils it had a nullpointer

Axenari

@Pelayori I tried the TWeakObjectPtr thing, the weird thing is it comes thru as a nullpointer at random times. Whenever i throw it on the ground like 15 seconds before it spoils it had a nullpointer

Then dropped items re create the item

9:43 AM

Probably not the best idea to store the pointer since items get created and destroyed a lot

But it stays on the ground just fine for 1 minute 40 seconds

9:51 AM

thats the weird part

The item gets destroyed and a clone is created most likely

10:06 AM

So the original ptr is not valid anymore

Any way you can think of doing this?

10:11 AM

To be clear, ive got a custom item of which there should only be 1, I can have a pointer to the item as theres only 1 Whenever it cannot detect the item it should fire a function

Im kind of out of options

Axenari

Im kind of out of options

Did you try get spoling time hook?

2:15 PM

Check if it's your item, and if spoiling time is due to something

2:15 PM

Spoiling time might be world seconds, if so then you just do spoling_time - GetWorld()->GetTimeSeconds()

I did get that part

4:29 PM

Ive got an idea that ima test out, thanks for the tip

4:29 PM

It indeed is the time second thing brw

So, rn im having this issue. this is a spawned in structure by command

9:19 PM

it has the servers tribe id, its unlocked and yet i cannot access it

It may not have an inventory component @Axenari

If i make this my own tribe id it does actually have it

9:21 PM

Found this: AllowStructureAccess();

9:22 PM

but its used to set for 1 player

9:22 PM

i bet its something i need to set it to where everyone can access it

That’s now how access checks work

im confused to how i can access it when its my own tribe tho?

Maybe you need to replicate the bUnlocked field

Isnt it replicated as it tells in the yellow text unlocked?

It might just be the server knowing it's unlocked and setting the box name field to (Unlocked)

9:24 PM

Try force replicate or multicast property

(how do i do that?)

Try either: Structure->ForceReplicateNow(false, false); or Structure->MulticastProperty(FName("bIsLocked", EFindName::FNAME_Add)); (edited)

9:29 PM

If you can access it when it's your own tribe it might be client not aware of it

Which will be fixed w a replicate?

That you can access if unlocked

9:29 PM

It's just a guess, I don't know any of your setup

Its a simple SpawnActor w a few things added to it

9:31 PM

sidenote

Yeah, I can't find anything in the trophy base that prevents inventory access out of the usual checks (edited)

whenever i reload my plugin my MySql functions crash my server

9:32 PM

am i missing something with unloading or smthing?

It depends, mysql shouldn't crash on unload normally. But without knowing something of your setup it's hard to tell

nvm i think i know why.. my mysql is loaded on Init, i guess after reload it doesnt init anymore?

On Init game hook?

Yes

Yeah, could be an issue

9:34 PM

You can add a check on Load() and init if server is ready

Its safe to load at any other point right?

9:35 PM

or does it need to be at init

if (ArkApi::GetApiUtils().GetStatus() == ArkApi::ServerStatus::Ready)
{
    // code...
}

9:35 PM

Yeah, should be safe

Alr ty

9:36 PM

Ill try the other thing asap

Update, no difference

9:43 PM

        here->bForceNoPinLocking();
        here->bIsLocked() = false;
        here->bIsPinLocked() = false;
        primal_structure->bBPOverrideAllowStructureAccess() = true;
        here->ForceReplicateNow(false, false);
        here->MulticastProperty(FName("bIsLocked", EFindName::FNAME_Add));

Try replicating the team id

here being the very vague naming of the inventory

It shouldn’t be yellow if it is your team

Its not supposed to be my team

9:44 PM

this is supposed to be an server spawned structure everyone should be able to open

Why are you enabling bp override allow access?

Axenari

this is supposed to be an server spawned structure everyone should be able to open

Use an obi

9:44 PM

Or a drop

9:45 PM

Both would be more obvious too

That makes a custom function run to check if the player is allowed and it's likely returning no always

And should work without anything special

ive got no idea Pelayori

9:45 PM

ill delete it but i dont think itl make a change?

9:45 PM

substitute, its going to be an trophy inside of it, a custom one that lights up

9:45 PM

so it makes sense to have it in there

You are enabling a function, which the structure does not implement, and it's likely preventing access always

Oh, on my way to test it

9:47 PM

Removed it, no success yet D:

and what is "here"?

    auto actor = world->SpawnActor(structure_class, &location, rotation, &params);
    auto* primal_structure = static_cast<APrimalStructure*>(actor);
    primal_structure->HealthField() = primal_structure->MaxHealthField();
    primal_structure->StructureIDField() = 10 + 1;
    primal_structure->TargetingTeamField() = database->getServerTribeID();
    if (primal_structure->IsA(APrimalStructureItemContainer::GetPrivateStaticClass())) {
        APrimalStructureItemContainer* here = static_cast<APrimalStructureItemContainer*>(primal_structure);
        here->bForceNoPinLocking();
        here->bIsLocked() = false;
        here->bIsPinLocked() = false;
        here->ForceReplicateNow(false, false);
        here->MulticastProperty(FName("bIsLocked", EFindName::FNAME_Add));
    }

9:49 PM

Here is the context

9:49 PM

& yes im aware i should name things more clear, im an idiot

Hmm that structure id I don't know if that is entirely correct

ill try and delete that one, see if it changes anything

9:50 PM

Still nope

No idea then

My ida is broken, any chance you can look me up which things get added normally? so i can replicate the process of a normal placement as much as possible?

Spawning is fine, but there's something else we are not seeing for the unlockt (edited)

10:00 PM

what if you just keep the bis locked = false and replicate / multicast (edited)

I can try that soon

Still doesnt work D:

Hello, Sometimes my code enters the if condition bellow, and sometimes it does not:

std::wstring blueprint = L"/Game/PrimalEarth/CoreBlueprints/Weapons/PrimalItem_WeaponMetalHatchet.PrimalItem_WeaponMetalHatchet_C";
UObject* object = Globals::StaticLoadObject(UObject::StaticClass(), nullptr, blueprint.c_str(), nullptr, 0, 0, true);
if (!object)
    // Error

It seems like I need to wait for the garbage collector or something in the background to happen before I can call this code again. If I call it two times in a row without waiting a little the second call returns NULL. I don't know what is happening exactly and I'm searching a way to always be able to load the blueprint object. Any help appreciated thank you.

You might be better off calling UVictoryCore::BPLoadObject or BPLoadClass

alright I don't know this namespace, I'm going to look at it thank you (edited)

6:58 PM

also I was trying to reach the ArkModding discord and you helped me on the other Discord server ^^

Oh, true

but I'm actually using ARK Server API, so I guess it's useless for me to go there, I'm better here right?

6:59 PM

they use Unreal dev kits and so on on the other Discord I suppose

It isn't useless, I find some examples of stuff I don't get the idea to do, but in bp code which can be easily translated into cpp

6:59 PM

Or ark quirks they know about and we don't

7:00 PM

It's a good resource with discord search

ok

But this I'd use bp load object/class. only time I needed to use static load object was to load icon objects to use in notifications/chat

I used this based on the old Michidu repos ^^

Do you need the class or an object itself? Because you could load class and then get the default object, cast to the specific object type and get vars from there

it's actually working almost perfectly, just sometimes the function randomly returns NULL for some reason

7:02 PM

I'm just trying to instantiate a new item in game and then make a player drops this new item in front of him

You also have StringReferenceToClass which works similarly to BPloadClass

OSubMarin

I'm just trying to instantiate a new item in game and then make a player drops this new item in front of him

Then you'd want to load the class

7:02 PM

not the object itself

Hmm, there's an api utils function for spawning and dropping an item

haha

7:04 PM

complete function above, but I will have to look what you told me about

Well yeah, the class is an object technically so that isn't wrong either

yes it's mostly copy pasted from API utils

Never used said function so can't say if it works or not

I randomly enter the

if (object == nullptr)
        return false;

sometimes

Yeah, shouldn't happen if the class is there

7:05 PM

Try using bpload class

yep

And just set archetype to that class

thanks

np

I'm doing some custom mods for the cluster I'm hosting, but later on I might be able to extract some features from it for a public mod. Actually the only thing that could be interesting is the additional rcon command "zipsavegame" that creates a zip archive of all the .ark/.arkprofile/.arktribe files asynchronously using std::thread.

7:18 PM

I use it because I don't host on my machine so I need to get these data from FTP

7:18 PM

Not really worth to release a mod just for that, it would fit better in ExtendedRCON mod and it's still for a specific usage. (edited)

that's cool

Im trying to create an FItemNetID, If found: FItemNetID item_id; item_id.ItemID1 = id1; item_id.ItemID2 = id2; but couldnt find what id1 and id2 are supposed to be. can anyone help me out?

The item ids

12:47 PM

FItemNetId has 2 ints, id1 and id2

Randomizing them is fine when making an item

1

so there's no function to get a new one that does not exist? (edited)

7:36 PM

indeed iterating over every items just to make sure the ids are not taken is probably not worth unless very well optimised

To create a new item just use UPrimalItem::AddNewItem with nullptr inventory if you don't want to add it to the inventory yet. Then you could add it with inventory->AddItemObject(item)

yep that's what I'm doing, I was just reacting to FItemNetID problem above ^^

7:38 PM

I switched to BPLoadClass as you suggested

Results?

it removed the unpredictable aspect

7:40 PM

I still have one weird error and I have to run one portion of the code a second time so still not perfect but now it's working, I just need a little more tests to solve the remaining problem

Which error?

I have one function for spawning an item into a player's inventory and another to spawn and drop an item at the feet of a player. The error only happens with the spawn drop function. I modified a little (but not tested yet), I have this at the moment:

static bool MySpawnDrop(unsigned long long steamId, FString* blueprint, int amount, float item_quality, bool force_blueprint, float min_random_quality, float life_span)
{
    ArkApi::IApiUtils& utils = ArkApi::GetApiUtils();

    AShooterPlayerController* aShooterPC = utils.FindPlayerFromSteamId(steamId);
    if (!aShooterPC)
        return false;

    UClass* bpUClass = UVictoryCore::BPLoadClass(blueprint);
    if (!bpUClass)
        return false;

    TSubclassOf<UPrimalItem> archetype = TSubclassOf<UPrimalItem>(bpUClass);
    UPrimalItem* item = UPrimalItem::AddNewItem(archetype, nullptr, false, false, item_quality, false, amount, force_blueprint, 0.0F, false, nullptr, min_random_quality);
    if (!item)
        return false;

    ADroppedItem* dropped = NULL;
    FVector zero_vector{ 0.0F, 0.0F, 0.0F };
    FRotator rot{ 0.0F, 0.0F, 0.0F };
    FVector pos = utils.GetPosition(aShooterPC);

    FItemNetInfo* info = static_cast<FItemNetInfo*>(FMemory::Malloc(0x400));
    if (!info)
        return MyRemoveItem(&item);
    try
    {
        RtlSecureZeroMemory(info, 0x400);
        item->GetItemNetInfo(info, false);
        TSubclassOf<ADroppedItem> archetype_dropped = TSubclassOf<ADroppedItem>(bpUClass);
        dropped = UPrimalInventoryComponent::StaticDropNewItemWithInfo(aShooterPC, info, archetype_dropped, &rot, true, &pos, &rot, true, false, false, true, nullptr, zero_vector, nullptr, life_span);
    }
    catch (...) {}
    FMemory::Free(info);

    if (dropped == NULL)
        return MyRemoveItem(&item);

    return true;
}

(edited)

7:50 PM

and this one is working without errors:

static FORCEINLINE bool MySpawnInInventory(unsigned long long steamId, FString* blueprint, int amount, float item_quality, bool force_blueprint, float min_random_quality)
{
    UClass* bpUClass = UVictoryCore::BPLoadClass(blueprint);
    if (!bpUClass)
        return false;

    AShooterPlayerController* aShooterPC = ArkApi::GetApiUtils().FindPlayerFromSteamId(steamId);
    if (!aShooterPC)
        return false;

    AShooterCharacter* aShooterCharacter = static_cast<AShooterCharacter*>(aShooterPC->CharacterField());
    if (!aShooterCharacter)
        return false;

    UPrimalInventoryComponent* inventoryComponent = aShooterCharacter->MyInventoryComponentField();
    if (!inventoryComponent)
        return false;

    // Probably some cleaner way to check if item is stackable here:
    UPrimalItem* tmp = (UPrimalItem*)(bpUClass);
    UPrimalItem* tmpB = (UPrimalItem*)(bpUClass);
    int quantityOverride = 2;
    bool canStack = (inventoryComponent->bAllowItemStacking()() && tmp && tmpB && tmp->CanStackWithItem(tmpB, &quantityOverride));

    TSubclassOf<UPrimalItem> archetype = TSubclassOf<UPrimalItem>(bpUClass);
    UPrimalItem* item = UPrimalItem::AddNewItem(archetype, nullptr, false, !canStack, item_quality, false, amount, force_blueprint, 0.0F, false, nullptr, min_random_quality);
    if (!item)
        return false;

    bool isUsableConsumable = item->IsUsableConsumable();
    try
    {
        UPrimalItem* item2 = inventoryComponent->AddItemObjectEx(item, false, false, !canStack, true, !isUsableConsumable, false, aShooterCharacter, false, nullptr, false);
        if (item2 == NULL)
            return MyRemoveItem(&item);
    }
    catch (...)
    {
        return MyRemoveItem(&item);
    }

    return true;
}

7:52 PM

so yeah my problem is only on the MySpawnDrop() function. On the first call I enter the

if (dropped == NULL)
        return MyRemoveItem(&item);

but on second call it works

7:53 PM

I will test this version cause it changed a bit but I will let you know ^^

7:53 PM

ho and :

static FORCEINLINE bool MyRemoveItem(UPrimalItem** item)
{
    // Probably some cleaner way to make sure item has been removed from game here:
    try
    {
        if ((*item)->bAddedToWorldItemMap()())
            (*item)->RemoveFromWorldItemMap();
        (*item)->ConditionalBeginDestroy();
        (*item) = NULL;
    }
    catch (...) {}
    return false;
}

7:54 PM

I'm kinda going ham to get rid of previous item haha, probably some cleaner way

UPrimalItem* tmp = (UPrimalItem*)(bpUClass);
    UPrimalItem* tmpB = (UPrimalItem*)(bpUClass);

I'd use (UPrimalItem*)(bpUClass->GetDefaultObject(true));

ah right

AShooterCharacter* aShooterCharacter = static_cast<AShooterCharacter*>(aShooterPC->CharacterField()); Also this will get the dino pawn (and thus cast is null) if riding dino. You can use aShooterPc->GetPlayerCharacter() as a more reliable way to get the player character

1

I want real instances not just class

You could also try other static drop functions, there's 3 of them. There's Static Drop Item which will take an existing's FItemNetInfo*, and Static Drop New Item which takes class and just creates a new item then drop it

1

7:57 PM

For remove, there's inventory functions for it, which have return bools for safety

7:58 PM

bool RemoveItem(FItemNetID * itemID, bool bDoDrop, bool bSecondryAction, bool bForceRemoval, bool showHUDMessage)

yes but I want to clean item in case of drop error

7:58 PM

so the item is not in any inventory

ah well

(I created it with nullptr) (edited)

7:59 PM

so yeah I tried the dirty hack above and cross finger so that it doesn't mess up ^^ (edited)

I'm not confident about that way

8:00 PM

If it's not dropped nor in any inventory you could just leave it there and if it's not referenced or taken care of eventually it'll get cleaned by GC

yeah basically I'm just telling GC I'm done with it, so that eliminates a possible memory leak (unused memory), but I take the risk of a pointer still pointing at it somewhere in the game's logic (edited)

8:01 PM

(*item)->ConditionalBeginDestroy();
        (*item) = NULL;

This tells GC I'm done with it, if I'm correct (edited)

8:02 PM

and I saw there was these two functions bAddedToWorldItemMap() RemoveFromWorldItemMap() so I added them too

8:02 PM

so far no Segmentation Fault

^^ (it would be safer to just remove the MyRemoveItem call I agree) (edited)

UPrimalItem::RemoveFromWorldItemMap() this call could be a bad thing or the thing saving me from segfault, I don't know what it does actually (edited)

8:14 PM

based on function name I just assumed it has to do with the list of UPrimalItem in the world (maybe it's not even called I didn't check if I enter this if condition yet). (edited)

there's no way of getting the inner logics of game functions except by testing them or IDA I suppose? (this discord and repositories is already very good sources of knowledge, also I want to get into the other arkmodding discord but still getting a 404) (edited)

9:27 PM

I kinda miss managed code for that ^^ (edited)

OSubMarin

there's no way of getting the inner logics of game functions except by testing them or IDA I suppose? (this discord and repositories is already very good sources of knowledge, also I want to get into the other arkmodding discord but still getting a 404) (edited)

if it's a function made strictly for ARK, the only way you can find info about it is via IDA or maybe devkit documentation

9:49 PM

if it's a function from Unreal imported into the game, then you can just google it and unreal docs will have all the info about it

true, I've already read a little* Unreal documentation already (edited)

9:52 PM

and sorry for the edits, searching my words sometimes, english is not my primary language

OSubMarin

indeed iterating over every items just to make sure the ids are not taken is probably not worth unless very well optimised

There’s no concern with two randomized ids

3:17 AM

It’s a large numbers birthday problem

3:17 AM

Both random id 1&2 are large numbers, so the odds A or B are the same are very small

3:17 AM

For an item to be a duplicate both A & B must be the same

3:17 AM

Not just A or B

3:18 AM

But it’s already unlikely two items will have A or B be the same, significantly less A and B

3:18 AM

I think it is an unsigned short, so you have 1/2^16 for A or B being the same

3:18 AM

And what like 1/2^32 both are?

perhaps larger odds, it's been a hot minute since I've had to figure probability out

3:26 AM

tldr; two random ids for A and B are essentially always unique

yeah, except they're not and you can still end up with duplicate if unlucky (or very unlucky if you prefer) ^^ (edited)

9:45 AM

but I get your point, it seems safe enough for sure (edited)

OSubMarin

yeah, except they're not and you can still end up with duplicate if unlucky (or very unlucky if you prefer) ^^ (edited)

Randomization is literally how the game engine generates them

9:52 AM

The chances that you generate two of the same random Id sets is so significantly low it’s less than a rounding error on a rounding error

you're not taking into account the number of already generated IDs tho

You do know how significant figures works right?

no but I know about probabilities

Even if you had 100 million items active you still have less than a 3% chance of a duplicate (actual value) (edited)

alright, seems safe enough for sure

Item ids are also often discarded/regenerated

9:55 AM

It really is a really insignificant chance of a duplicate

1

9:55 AM

If you manage to get one, buy a lottery ticket

ok haha ^^

9:57 AM

I guess the AddNewItem() function is responsible for generating these IDs

Probably, I’m not at my pc atm

seems a bit like a waste of time to generate random IDs when you could just use a static float somewhere

10:01 AM

I guess it has to do with networks constraints, or maybe security so that you cannot guess IDs easily (edited)

Hey! im still struggling with the same things, this is like a duo issue im dealing with right now

4:15 PM

4:16 PM

4:17 PM

Picture 1: Trophy stand that i spawned in with code, this doesnt look right to me but i generally dont care it looks weird. but it might cause the issues in pic two

4:17 PM

Picture 2: this is the trophy i spawn in with code. this normally has a spoil timer of 1 hour. when i spawn it in on the trophy stand it 1. does not switch to the trophy slot, 2. doesnt have a spoil timer (i did not test to spawn in any other inventory yet) (edited)

4:18 PM

my goal: structure is from the server, this is accessable by everyone. i want to be able to respawn the trophy with a function. it should be with a full spoil timer (the stand makes it never spoil as the multiplier is very high) and in the trophy slot.

4:19 PM

code 1: spawning of the base.

        auto actor = world->SpawnActor(structure_class, &location, rotation, &params);
        auto* primal_structure = static_cast<APrimalStructure*>(actor);
        primal_structure->HealthField() = primal_structure->MaxHealthField();
        primal_structure->TargetingTeamField() = database.get()->getServerTribeID();
        if (primal_structure->IsA(APrimalStructureItemContainer::GetPrivateStaticClass())) {
            APrimalStructureItemContainer* here = static_cast<APrimalStructureItemContainer*>(primal_structure);
            here->BeginPlay();
            here->bIsLocked() = false;
            here->ForceReplicateNow(false, false);
            here->MulticastProperty(FName("bIsLocked", EFindName::FNAME_Add));
        }

4:19 PM

code 2: spawning of the trophy:

                    FString classname = FString(TrophyBPPath);
                    UObject* trophyclass = UVictoryCore::BPLoadClass(&classname)->GetDefaultObject(true);
                    UPrimalItem* alphatrophyitem = static_cast<UPrimalItem*>(trophyclass);
                    if (alphatrophyitem) {
                        alphatrophyitem->NextSpoilingTimeField() = ArkApi::GetApiUtils().GetWorld()->TimeSecondsField() + 3600;
                        alphatrophyitem->UpdatedItem(false);
                        static_cast<APrimalStructureItemContainer*>(Stand)->MyInventoryComponentField()->AddItemObject(alphatrophyitem);
                        alphatrophyitem->AddToSlot(-1, true);

I am not sure adding an item class default object to an inventory can bring anything good

4:20 PM

Since all items get their settings fro CDO instance (edited)

4:20 PM

You can use UPrimalItem::AddNewItem and set inventory to nullptr, then you can use the add item object func

4:21 PM

About the structure, what is the issue exactly?

The structure does not really have an issue, i thought it might be the cause of the issue

4:25 PM

im going to try your method and update

4:28 PM

How do i get TSubClassOf

4:28 PM

@Pelayori

You can just input UClass

& how do i get that xD

You get it from bp load class

Mhh ive got a line for that in my previous code but it made an UObject tho

because you are getting the class default object

4:30 PM

Either way, UClass is an UObject too

4:30 PM

The return type of bp load class is UClass pointer

ah sorry, i get confused w these terms sometimes

4:30 PM

thanks!

4:33 PM

it works!

4:33 PM

except that it doesnt switch to the equip slot

4:34 PM

alphatrophyitem->AddToSlot(-1, true);

I don't know the indexes for the slots

4:34 PM

But is -1 one of them?

if i index the slot for equip it says its -1

Try using the functions to add to slot in the inventory

only function i could find that might work is: ServerEquipItem

ServerAddItemToSlot or ServerAddItemToSlot_Implementation might do the trick

4:38 PM

Maybe try using 0 for the index

no result

try equpping it manually, and loop trough the items, and log the slot index to console

tried this on an additem hook: Log::GetLog()->warn(item->SlotIndexField());

4:52 PM

it always returns -1 tho, even if it enters normal inv

that might be too early

interesting, ill try it another way!

5:00 PM

very weird

5:00 PM

in a fabricator?

That's why I think -1 is not the right index to equip on the slot

5:01 PM

-1 is likely used when no slot is used

5:01 PM

I'd try 0, 1 indexes as those seem logical, but this is ark lol (edited)

it depends on the inventory

5:02 PM

but each inventory has 2 arrays

5:02 PM

for items to hold

5:02 PM

one is for equipped items and the second array is for just regular inventory slots

Whatever i try it doesnt work, inventory->CanEquipItem(item) returns true

6:29 PM

but: item->EquippedItem();

6:29 PM

and item->AddToInventory(static_cast<APrimalStructureItemContainer*>(Stand)->MyInventoryComponentField(), true, false, nullptr, false, false, false);

6:29 PM

do not do anything

none of those are to add to the slot

6:30 PM

to add the item to the inventory call inventory->AddItemObject

6:31 PM

equippedItem() is just an event that runs when an item is equipped

6:31 PM

doesn't actually equip it

Adding to a slot simply does not work for me, tried it all

6:32 PM

if i add it w a line and manually equip it it works

6:32 PM

now im looking for a way to make it equip, as slots dont work at all

Did you try adding it to slot 0?

6:38 PM

I've seen examples without the force bool

I did

6:38 PM

Ive not tried without force bool

6:39 PM

I cannot try it rn sadly but i guess ill try that next

6:39 PM

Im fairly sure the trophy stand itself has flaws too tho, it isnt registered in all structures (i cannot find it by id for example)

6:40 PM

Now i dont mind it as it shows and it works fine but it might be a cause

You could use AddItemObjectEx with bEquipItem true. That's what cryopods use to add + equip saddle (edited)

Hmm, i fixed that issue

12:36 PM

now, how do i loop all inventories?

12:37 PM

tried to modify this: UGameplayStatics::GetAllActorsOfClass(ArkApi::GetApiUtils().GetWorld(), APrimalStructure::GetPrivateStaticClass(), &FoundActors);

12:37 PM

but it works different

12:38 PM

actually i try to loop every item on the server on startup

You can change the class to APrimalStructureItemContainer

1:23 PM

So then you will only get structures with inventory, on each loop cast the AActor* pointer of the array to primal structure item container

But what about player invs, item bags etc?

You have various options which can use together 1) Primal Characters (players/dinos) 2) ShooterCharacters (only players) 3) Primal Dino Characters (only dinos) 4) Primal Structure Item Container (all structures, bags too)

1:34 PM

players/dinos will get also dead ones, so if you need to do anything other than checking inventory make sure they aren't dead

Ty!

I'm trying to use the CheatManager to give an item to a player but I'm not able to make it work.

static bool MyGiveItemNum(unsigned long long steamId, int itemNumId, int quantity, float quality, bool forceBlueprint)
{
    ArkApi::IApiUtils& utils = ArkApi::GetApiUtils();

    AShooterPlayerController* aShooterPC = utils.FindPlayerFromSteamId(steamId);
    if (!aShooterPC)
        return false;

    UShooterCheatManager* cheatManager = utils.GetCheatManager(); // I tried with "GetCheatManagerByPC(aShooterPC);" it doesn't work either
    if (!cheatManager)
        return false;

    cheatManager->GiveItemNumToPlayer(aShooterPC->GetLinkedPlayerID(), itemNumId, quantity, quality, forceBlueprint);
    return true;
}

It works as expected on first call, but on subsequent calls nothing happens. If I drop the item obtained with first call and call my function again it is now working, but item I receive is the same item that I just dropped (if I pick the dropped item it vanishes as it is already in my inventory).

1:43 PM

Look like some item regeneration is not happening as I keep getting the same item over and over.

why all this hassle lol

1:44 PM

PC->GiveItem(&SpawnedItems, &fBlueprint, Amount, Quality, IsBlueprint, false, 0);

1:44 PM

PC is PlayerController

I tried this too

1:44 PM

same result

this works 100%, it's used in every single plugin

hmmm, I was almost sure to have tried this tho, let me give it another try

is your PlayerController null?

no the PlayerController is alright

1:46 PM

at least it seems OK (I don't enter the !aShooterPC condition)

then this function will work (as long as you're not on the re spawn screen)

the function I copy pasted above ?

no, the function i sent

ah ok

1:46 PM

thanks

I get the same result with PC->GiveItem()

@WETBATMAN

2:16 PM

static bool MyGiveItemNum(unsigned long long steamId, FString* blueprint, int quantity, float quality, bool forceBlueprint)
{
    ArkApi::IApiUtils& utils = ArkApi::GetApiUtils();
    AShooterPlayerController* aShooterPC = utils.FindPlayerFromSteamId(steamId);
    if (!aShooterPC)
        return false;
    TArray<UPrimalItem*> spawnedItems;
    if (!aShooterPC->GiveItem(&spawnedItems, blueprint, quantity, quality, forceBlueprint, false, 0))
        return false;
    return true;
}

First call works but subsequent call nothing happens (well actually I think I know what happens, it gives me the same item but the anti-dupe check is preventing the same item from getting added again) (edited)

2:18 PM

And I have the exact same problem with UPrimalItem::AddNewItem() which every times returns the same item to me instead of creating a new one. (edited)

2:20 PM

actually I enter the !aShooterPC->GiveItem( False condition on the 2nd call (edited)

OSubMarin

    if (!aShooterPC)
        return false;

        return false;
    return true;
}

First call works but subsequent call nothing happens (well actually I think I know what happens, it gives me the same item but the anti-dupe check is preventing the same item from getting added again) (edited)

do you get the anti dupe error in server console? (edited)

ah no that's just a supposition

2:25 PM

I don't even check in game console

if the server removes something for anti dupe, it always appears in server console

2:25 PM

i never had issues with this function

2:25 PM

what's the quantity you're spawning

1

2:26 PM

with quality 2

2:26 PM

force bp false (edited)

are you sure the bp path is correct?

yes

2:26 PM

Blueprint'/Game/PrimalEarth/CoreBlueprints/Weapons/PrimalItem_WeaponMetalHatchet.PrimalItem_WeaponMetalHatchet'

2:26 PM

otherwise it would not work I guess

so you get the item added?

yes on first call the item is added with proper quality, but on second call I enter the second if condition, and what is weird now if I call it a third time it works again

2:28 PM

but now I will enter two times the second if condition before next call is working

2:28 PM

then three times,

2:28 PM

etc

2:28 PM

so weird xD

checking the function it seems to return false if the character or the inventory are null

2:29 PM

how do you call the function?

I call it from a seperate thread that I create with std::thread

ah

2:30 PM

you can't multi thread in this game

2:30 PM

lmao xD

yeah that will crash 99% of the time

2:30 PM

maybe you'll get lucky that 1%

2:30 PM

you can probably get away with multi threading if you lock the game tick

2:30 PM

but that's not really multi threading at that point

2:30 PM

since you pause the game

ok I will have another try on current thread next time

2:31 PM

is it safe to call it upons ChatMessage trigger from ArkApi ?

in main thread?

2:32 PM

everything is safe in main thread

in this function :

bool ChatMessageCallback(AShooterPlayerController* _AShooterPlayerController, FString* Message, EChatSendMode::Type Mode, bool spam_check, bool command_executed)
{
// here
}

just nullptr check the variables you're using

2:32 PM

you can add your own chat message

2:32 PM

ArkApi::GetCommands().AddChatCommand("/bp", &GetIP);

2:32 PM

like this

2:32 PM

first param is the chat message it will intercept

2:33 PM

second param is the function invoked for that command

ah ok I didn't know I was just parsing Message for /bp

I guess it's doing same thing anyway x)

API has callback binders for console commands, RCON commands and chat commands

good

OSubMarin

I guess it's doing same thing anyway x)

yes but it's kinda unclean to hook it this way when the API can just manage it all for you

true I will make use of it

2:36 PM

can you pass arguments to the chat command?

it has predefined params

2:37 PM

void GetIP(AShooterPlayerController* PC, FString* message, int mode)

thanks

It works way better without std::thread thanks again WETBATMAN

4:42 PM

it seems the item quality is always random w/e float value I set, but that's another problem ^^ (edited)

Any game stuff don't multi thread it. I use threading quite a bit on MySQL caching for example. There's an example on that on the permissions plugin source

Well my ZipSavegame RCON command was working nicely in a separate thread so I thought I could also manipulate the game from there

4:45 PM

my bad

4:46 PM

What are you multithreading? calls to MySQL or calls to game code?

Calls to Mysql, doing queries to fetch the data

ah ok that's why it works

Then if I need to do anything I do it on the main thread

ok

4:50 PM

regarding the item quality that seems random, I guess I will have to use one the method that expose the "min_random_quality" parameter

4:50 PM

correct?

OSubMarin

it seems the item quality is always random w/e float value I set, but that's another problem ^^ (edited)

you can set exact quality with the function i posted in examples

thanks

oh actually it's not posted in examples

are you sure you posted it in exemples?

my bad

yeah ^^

4:52 PM

no problem

void SetItemStatValue(UPrimalItem* item, EPrimalItemStat::Type item_stat_type, const float new_value)
{
    float newStat = 0.f;

    if (item_stat_type == EPrimalItemStat::Armor || item_stat_type == EPrimalItemStat::MaxDurability)
    {
        item->ItemStatValuesField()()[item_stat_type] = 0;
        float old_stat_modifier = item->GetItemStatModifier(item_stat_type);
        item->ItemStatValuesField()()[item_stat_type] = 1;
        newStat = (new_value - old_stat_modifier) / (item->GetItemStatModifier(item_stat_type) - old_stat_modifier);
    }
    else if (item_stat_type == EPrimalItemStat::WeaponDamagePercent)
    {
        item->ItemStatValuesField()()[item_stat_type] = 0;
        float min_damage = item->GetItemStatModifier(item_stat_type);
        item->ItemStatValuesField()()[item_stat_type] = 65535;
        float max_damage = item->GetItemStatModifier(item_stat_type);

        float diff = max_damage - min_damage;
        float multiplier = 65535 / diff;

        newStat =  new_value / 100.f - min_damage;
        newStat *= multiplier;
        newStat += 1.f;
    }

    if (newStat >= 65536.f)
        newStat = 65535;

    item->ItemStatValuesField()()[item_stat_type] = newStat;

    if (item_stat_type == EPrimalItemStat::MaxDurability)
    {
        if (item->bUseItemDurability()())
            item->ItemDurabilityField() = item->GetItemStatModifier(item_stat_type);
    }

#ifdef Ark
    item->UpdatedItem(false);
#endif
#ifdef Atlas
    item->UpdatedItem();
#endif
}

4:52 PM

here

ah, that's seems a bit big for my need (I don't need to set the exact stat) (edited)

4:53 PM

I'm fine with the random aspect, I just want to always have a Rare item if I set quality to 2, but you can get common and unusual item it seems

4:53 PM

I think the min_random_quality is supposed to prevent having common/unusual

4:56 PM

I will do some tests and fallback to set an exact value with your method if I don't succeed with the min_random_quality

You can always try with UPrimalItem::AddNewItem or some other funcs (edited)

4:56 PM

Add new item has more properties to init the item (edited)

yep that's what I wanted to do, because last time I tried them I was still in another thread and I was not understanding why everything was acting so weird (unpredictable function returns)

Just threads

OSubMarin

I call it from a seperate thread that I create with std::thread

As Batman said you can’t multithread

6:04 PM

A large amount of functions will throw an assert if they are not run on the game thread

not when you do catch (...) { /*doNothing*/ } like me ^^ (edited)

6:07 PM

well, maybe it throws but I didn't deal with

Catch(...) is dangerous. We had some crash prevention in the base API and we ended up removing it because Michidu said it was very dangerous to catch exceptions like that

yes I know it's bad

6:08 PM

it's just for quick tests purposes

6:08 PM

generally ^^

Well then it's fine, just don't use for production

1

handling errors with exceptions is generally bad, not only the catch (...) { /*doNothing*/ } (but this one is the worst) (edited)

6:13 PM

it uses a lot of resources

It works perfectly without std::thread, beautiful. (edited)

7:31 PM

You've done a great work on this API congrats.

    // Get target player's inventory
    UPrimalInventoryComponent* targetInventory = target->GetPlayerInventoryComponent();
    if (!targetInventory)
        return false;

    // Get target player character
    AShooterCharacter* targetCharacter = target->GetPlayerCharacter();
    if (!targetCharacter)
        return false;

    // Get item class
    UClass* bpUClass = UVictoryCore::BPLoadClass(blueprintPath);
    if (!bpUClass)
        return false;

    // Is item stackable?
    UPrimalItem* defaultItem = (UPrimalItem*)(bpUClass->GetDefaultObject(true));
    int quantityOverride = 2;
    bool canStack = (targetInventory->bAllowItemStacking()() && defaultItem && defaultItem->CanStackWithItem(defaultItem, &quantityOverride));

    // Create the item
    UPrimalItem* item = UPrimalItem::AddNewItem(TSubclassOf<UPrimalItem>(bpUClass), nullptr, false, !canStack, quality, false, quantity, forceBlueprint, 0.0F, false, nullptr, minRandomQuality);
    if (!item)
        return false;

    // Add the item to target's inventory
    if (!targetInventory->AddItemObjectEx(item, false, false, !canStack, true, !item->IsUsableConsumable(), false, targetCharacter, false, nullptr, false))
        return false;

    // Return success
    return true;
}

7:48 PM

I use this template now as it gives a lot of control on the spawned item (I didn't try all parameters yet, like the ClampStats boolean and MaxDifficultyClamp float value).

7:49 PM

But I tried the minRandomQuality and it works, I'm able to always get a Rare item by setting it to 2 (and still getting a random rare quality). (edited)

2

You could probably do this to reduce your temporary variables

    // Is item stackable?
    UPrimalItem* cdo = (UPrimalItem*)(bpUClass->GetDefaultObject(true)); //(UPrimalItem*)(bpUClass);
    int quantityOverride = 2;
    bool canStack = (targetInventory->bAllowItemStacking()() && cdo && cdo->CanStackWithItem(cdo, &quantityOverride));

8:00 PM

bpUClass->GetDefaultObject(true) should be returning the same pointer anyways for tmp and tmpB (edited)

yep I was planning on checking pointers values

8:01 PM

but if you're confident enough I'll directly switch to that

CDO is the class default object

8:01 PM

it should never change

1

Yeah, UClass keeps a pointer to the CDO, and always returns the same one which it has stored. If it doesn't have it created a new one and stores it. So it should be the same always

For the function I posted above, would you recommend to add FORCEINLINE or not?

8:19 PM

static FORCEINLINE bool MyGiveItem(uint64 targetSteamId, FString* blueprintPath, int quantity, float quality, bool forceBlueprint, float minRandomQuality) { /*...*/ }

8:20 PM

I generally use inline for little function like arithmetic operations

FORCEINLINE is a non standard macro

8:20 PM

Use inline

alright, I'm asking this because I saw it everywhere on the API

8:21 PM

I don't even know if inline is worth in that case

8:21 PM

this function is kinda big

8:22 PM

I think I will leave it as a static func

8:22 PM

I'm not searching for that 1ms improvment anyway (edited)

Recommend reading

8:23 PM

https://docs.microsoft.com/en-us/cpp/cpp/inline-functions-cpp?view=msvc-160

Inline Functions (C++)

The C++ inline keyword can be used to suggest inline functions to the compiler.

8:23 PM

yeah you can read straight from the beginning that this constraint causes inline functions to behave as if they were instantiated functions

8:24 PM

I don't need that I think

8:25 PM

and I'm too lazy to test performance difference

If you put inline the compiler will decide

8:25 PM

The insertion, called inline expansion or inlining, occurs only if the compiler's cost-benefit analysis shows it's worthwhile.

yeah I'm almost sure it will decide to not inline this huge function (edited)

8:26 PM

which itself has probably inlines

8:26 PM

it can easily go in inlining nightmare

8:26 PM

I don't know x)

8:26 PM

static will be good enough!

8:29 PM

and thank you Substitute

8:34 PM

I like the

Even with __forceinline, the compiler can't inline code in all circumstances. The compiler can't inline a function if:  *Insert long list of things here*

on the MS link you gave me ^^ (edited)

8:36 PM

good thing that compilers are making sure everything is ok tho

8:37 PM

I guess even if I put FORCEINLINE everywhere it will work, just with a longer compilation time (edited)

Good Morning! It's not rocket science or anything.. but I thought of a very easy way to support multi languages in my plugins, and it's not something I've seen in any other configurations thus far, so I just figured I would share with the community (the snippet below is from my Offline Shaming plugin)

        // New Messaging config allows for multi language support.

I'm searching the best hook for catching when a player dies. I used the Hook Creator app and found the following but I'm not sure it's the best candidate :

12:59 PM

I just need the SteamID (uint64) of the player who died basically.

12:59 PM

With the less resources consumption possible ^^

AShooterCharacter::Die (edited)

thanks I will look at it

I get this little warning but I guess it's normal:

1:18 PM

DECLARE_HOOK definition not found but it compiles nicely without warnings.

(edited)

I'm a bit slow.. I haven't set that up yet pepeold

Now I'm hesitating between:

FString GetTribeName(AShooterPlayerController* playerController)
{
    auto playerState = playerController->GetShooterPlayerState();
    if (playerState)
    {
        FString playerOrTribeName;
        playerState->GetPlayerOrTribeName(&playerOrTribeName);
        return playerOrTribeName;
    }
    return  L"";
}

and

FString GetTribeName(AShooterPlayerController* playerController)
{
    auto playerState = playerController->GetShooterPlayerState();
    if (playerState)
    {
        auto tribeData = playerState->MyTribeDataField();
        if (tribeData)
            return tribeData->TribeNameField();
    }
    return  L"";
}

Or maybe there is an easier way to get the tribe name?

3:27 PM

I suppose AShooterPlayerState::GetPlayerOrTribeName() returns the player name if he is not in a tribe, is it correct? (edited)

OSubMarin

I suppose AShooterPlayerState::GetPlayerOrTribeName() returns the player name if he is not in a tribe, is it correct? (edited)

FString *__fastcall AShooterPlayerState::GetPlayerOrTribeName(AShooterPlayerState *this, FString *result)
{
  AShooterPlayerState *v3; // [rsp+40h] [rbp+8h]
  FString *v4; // [rsp+48h] [rbp+10h]

  v4 = result;
  v3 = this;
  if ( AShooterPlayerState::IsInTribe(this) )
    TArray<wchar_t,FDefaultAllocator>::TArray<wchar_t,FDefaultAllocator>(&v4->Data, &v3->MyTribeData.TribeName.Data);
  else
    TArray<wchar_t,FDefaultAllocator>::TArray<wchar_t,FDefaultAllocator>(&v4->Data, &v3->PlayerName.Data);
  return v4;
}

3:57 PM

correct

4:01 PM

if the player is alive you can also read the tribe name from the character

thank you

4:53 PM

btw, are you using IDA to get clean representations like this? when I tried with IDA I did not find the way to specify the pdb file so it looks very ugly ^^

Yes, he did

ok thank you, I'll have to search more for the proper configuration then

I believe you just use IDA to disassemble the exe

4:59 PM

it's a long process, they actually sent me the files instead

(edited)

well yes, but if it is not able to load the associated PDB file it won't put proper labels for function names and so on, only random aliases

I'm not an IDA expert like though, I'm still learning too

and in the .EXE, the path to the PDB is wrong, IDA tries to load it from a drive that do not even exist

5:00 PM

I'm sure there's an option in IDA to tell it where is the PDB file precisely

5:00 PM

I just did not find the option yet ^^

When @WETBATMAN see this, he'll laugh at me and then remedy the situation with the correct responses

lol

hmm i dont recall having to set that option, but i set it up a looong time ago

5:02 PM

and i'm old..so.. yeah

OSubMarin

and in the .EXE, the path to the PDB is wrong, IDA tries to load it from a drive that do not even exist

the path is correct

5:02 PM

because IDA scans the same folder for pdb

5:02 PM

but in case it doesn't find it, it will ask you to select it

ah ok, I remember getting an error message saying it did not find it, asking if it should look in local and Microsoft PDB stores. I do not recall being asked the location, only to look for local/MS stores, but I will have to try again.

the pdb link path won't match your drive ofc

5:04 PM

the link path is valid only for whoever compiled it (edited)

5:04 PM

however ida searches in the folder the .exe is in

alright then it's probably my fault, didn't look proper sections or w/e, I will test again thank you

you're decompiling ShooterGameServer right?

5:06 PM

it has to be a dedicated server install aswell

yes I think at the time I download the server version for that

5:07 PM

yes that's what I used

5:07 PM

I've some knowledge of ASM and C but still a beginner with IDA

5:08 PM

hmmm

5:09 PM

maybe I used ShooterGame actually, I can't remember xD

5:09 PM

I need to test again now.

both have pdb's

5:09 PM

it should have decompiled anyways lol

yeah but I didn't find interesting code, but I only briefly looked

5:10 PM

I'll have to try again and get a deeper dive this time now that I know a little better the game function prototypes (edited)

5:11 PM

if I'm able to find the GetPlayerOrTribeName function myself with IDA I should be able to find others then.

yes, you just need to search (ctrl+f) in the functions panel

5:36 PM

Hello, I'm currently trying to make a simple points system for my cluster. Here's what I have so far:

1:14 AM

void GivePointsHandler()
{
    // Static variables declaration and initialization.
    static std::map<unsigned long long, double> playersPoints = std::map<unsigned long long, double>();
    static int loopCnt = 0;

    // Iterate connected players
    AShooterPlayerController* shooterPc;
    AShooterCharacter* pc;
    unsigned long long steamId;
    const auto& player_controllers = ArkApi::GetApiUtils().GetWorld()->PlayerControllerListField();
    if (player_controllers.Num() > 0)
        for (TWeakObjectPtr<APlayerController> player_controller : player_controllers)
            if (shooterPc = static_cast<AShooterPlayerController*>(player_controller.Get()))
                if ((pc = shooterPc->GetPlayerCharacter()) && pc->IsConscious()) // If player is alive and conscious
                    if ((steamId = shooterPc->GetUniqueNetIdAsUINT64()) > 0Ui64) // If Steam ID is valid
                    {
                        if (playersPoints.find(steamId) == playersPoints.end())
                            playersPoints[steamId] = 1.0; // Player just earned his first point.
                        else
                            playersPoints[steamId] = (playersPoints[steamId] + 1.0); // Add 1 point to player points.
                    }
    if (++loopCnt >= 300) // Increment loop counter and check if it has been 5 minutes
    {
        // Make a local copy of current players points
        std::map<unsigned long long, double> playersPointsCopy = std::map<unsigned long long, double>(playersPoints);
        // Reset current players points
        playersPoints.clear();
        // Reset loop counter
        loopCnt = 0;
        // TODO: Process/save players points local copy asynchronously here
    }
}

(edited)

1:15 AM

void Load()
{
    ArkApi::GetCommands().AddOnTimerCallback("giveplayerpoints", &GivePointsHandler); // Call GivePointsHandler every second
}

void Unload()
{
    ArkApi::GetCommands().RemoveOnTimerCallback("giveplayerpoints");
}

PS: Edited code above with @WETBATMAN suggestions. . (edited)

1:16 AM

and the question: Is it the fastest way to iterate connected players?

1:16 AM

Because I know that AddOnTimerCallback() from the API will call the callback every seconds, so I need something very efficient there.

1:20 AM

Or maybe is there an equivalent of AddOnTimerCallback() that triggers every minute instead of every second? (edited)

OSubMarin

void GivePointsHandler()
{
    // Static variables declaration and initialization.
    static std::map<unsigned long long, double> playersPoints = std::map<unsigned long long, double>();
    static int loopCnt = 0;

    // Iterate connected players
    AShooterPlayerController* shooterPc;
    AShooterCharacter* pc;
    unsigned long long steamId;
    const auto& player_controllers = ArkApi::GetApiUtils().GetWorld()->PlayerControllerListField();
    if (player_controllers.Num() > 0)
        for (TWeakObjectPtr<APlayerController> player_controller : player_controllers)
            if (shooterPc = static_cast<AShooterPlayerController*>(player_controller.Get()))
                if ((pc = shooterPc->GetPlayerCharacter()) && pc->IsConscious()) // If player is alive and conscious
                    if ((steamId = shooterPc->GetUniqueNetIdAsUINT64()) > 0Ui64) // If Steam ID is valid
                    {
                        if (playersPoints.find(steamId) == playersPoints.end())
                            playersPoints[steamId] = 1.0; // Player just earned his first point.
                        else
                            playersPoints[steamId] = (playersPoints[steamId] + 1.0); // Add 1 point to player points.
                    }
    if (++loopCnt >= 300) // Increment loop counter and check if it has been 5 minutes
    {
        // Make a local copy of current players points
        std::map<unsigned long long, double> playersPointsCopy = std::map<unsigned long long, double>(playersPoints);
        // Reset current players points
        playersPoints.clear();
        // Reset loop counter
        loopCnt = 0;
        // TODO: Process/save players points local copy asynchronously here
    }
}

(edited)

your controller iteration is fine

1:24 AM

and yes there is a timer you can set that triggers every 1 min

1:25 AM

API::Timer::Get().RecurringExecute(&callback, 60, -1, false);

1:25 AM

like this

I can only see one that triggers every frame and one that triggers every seconds

be sure to include Timer.h

Ah ok

OSubMarin

I can only see one that triggers every frame and one that triggers every seconds

you can check time delay on your own also

This will execute &callback on the game's main thread right?

yes

ok

that's what the last param is for

thank you

!playerCharacter->IsDead()

1:27 AM

does this work for you?

1:27 AM

i remember it always crashing for me

I didn't test the above code yet

1:28 AM

I was expecting it to work

1:28 AM

now I will remove IsDead() check thanks ^^

playerCharacter->IsAlive()

1:28 AM

this is also redundant

1:28 AM

because the player character will always be null if the player is dead

1:29 AM

so it doesn't even make it to that

yeah I added it because I wanted to make sure he is not dead but I actually don't care that much, even if player is in dead state he can keep earning points. (edited)

1:29 AM

and yeah if the check is not even reached anyway...

1:29 AM

thanks!

1:31 AM

there is no need to unset the registered callback with the API::Timer method?

1:31 AM

like the RemoveOnTimerCallback()

there is not

1

1:31 AM

i'd check the time diff myself inside tick

a tick callback is called every frame right?

correct

I don't need that

OnTimerCallback is every second

I can have every minute it's fine ^^

1:32 AM

yeah every second is okay too I guess

1:32 AM

but because I'm not sure of my connected players iteration you know

you can count time wither either time(0) which returns unix epoch time

1:32 AM

or use the server time seconds field

1:32 AM

inside UWORLD

1:33 AM

the latter is dependent on the savefile

1:33 AM

it starts at 0 on server wipe

no I don't need such precision either ^^

1:33 AM

if the callback fire at 1.05 sec instead of 1.0 it's okay too (edited)

no, i meant that if you want to exec it every minute you can count the seconds until a minute has passed

I just need 0 lags at all

1:34 AM

ok but I would prefer a more optimized way than counting myself

1:34 AM

by using API's method typically

if you store the last check timestamp

1:35 AM

you can calculate the time difference

1:35 AM

but executing that every second should be fine anyway

yeah exactly

1:35 AM

I don't even need the time difference

1:35 AM

if the code guarantee me it's been about a second it's fine

1:36 AM

I was just scared that my PlayerController iteration is too slow for being used every seconds

1:37 AM

i use it to drain player's health in our stof game mode

1:37 AM

once sudden death starts

1:37 AM

i've even used this while we were hosting tournaments and nobody noticed any performance difference (edited)

that's perfect then, it's what I need

1:39 AM

you are calling GetPlayerCharacter() and GetCharacterStatusComponent() two times if you enter the second if ^^

1:40 AM

sorry I'm in optimisation mode haha

true heh

1:40 AM

but it only reads a pointer

yeah it's always a trade between memory and cpu

1:47 AM

what is that sudden death mode btw? you pick a random number and if you get unlucky you get suicided by the server? ^^

OSubMarin

what is that sudden death mode btw? you pick a random number and if you get unlucky you get suicided by the server? ^^

no, it's a survival of the fittest game mode

1:48 AM

the ring shrinks and once it reaches the middle of the map, players who are left inside drain health until they die

1:48 AM

kills give them hp back

1:48 AM

ah ok I see now

1:48 AM

fortnite famous for this mode x)

1:49 AM

so there's no russian roulette mod yet ^^

1:50 AM

/roulette

1:51 AM

that's something I could add, easy to do now that I have the proper setup

1:53 AM

now I'm thinking of an even more advanced "Russian roulette mod", which would first check if you're holding a charged weapon, and if the roulette finds the bullet it would fire the weapon before suiciding you (edited)

OSubMarin

yeah it's always a trade between memory and cpu

There is zero optimization issue there

2:40 AM

a smart compiler should inline the pointer read

OSubMarin

you are calling GetPlayerCharacter() and GetCharacterStatusComponent() two times if you enter the second if ^^

specifically this

2:42 AM

let's assume that we only have the eax register and that we only need to use mov to read from the pointer to keep things simple doing GetPlayerCharacter() should translate to something like

enter 0,0
mov eax, ptr
leave

but a compiler that inlines this should produce mov eax, ptr which is the same as if you had read from the pointer directly. (edited)

optimization issue I never said it was an issue tho

OSubMarin

now I'm thinking of an even more advanced "Russian roulette mod", which would first check if you're holding a charged weapon, and if the roulette finds the bullet it would fire the weapon before suiciding you (edited)

just spawn a particle emitter on the character's head.

OSubMarin

sorry I'm in optimisation mode haha

You said here. (edited)

2:44 AM

there is no optimization to be made.

yes you could have a pointer allocated on stack to save function resolution and call times

WetBatman wrote the most optimal code in his picture.

OSubMarin

yes you could have a pointer allocated on stack to save function resolution and call times

And that isn't true with a compiler that optimizes code.

2:45 AM

it should produce the same code

2:46 AM

no matter what you do, you need to read the previous level pointers before referencing the last one

2:46 AM

It should only produce a difference if you use -O0 for some reason

I prefer to not rely on compilers because sometimes two function calls instead of one can have consequences, I never said here it was a problem tho.

If you don't trust your compiler, then drop all languages other than assembly

if you prefer for me it's just more sane to have a pointer

2:47 AM

question of habbits I supposed

OSubMarin

I prefer to not rely on compilers because sometimes two function calls instead of one can have consequences, I never said here it was a problem tho.

You should also NEVER have this happen

2:47 AM

if that happens you either have undefined behavior

2:48 AM

or your code is impure and mutates the state

2:48 AM

both of which are generally frowned upon unless explicitly marked.

not really

2:48 AM

you could just have a function dealing with static variables or threads

Yes? There's entire languages now designed explicitly to prevent state mutation

OSubMarin

you could just have a function dealing with static variables or threads

These should be clearly marked

2:49 AM

properly written code should have zero surprises

or you could do like me, and store a pointer to function returns to avoid any additional resolutions and call times x)

until the pointer is invalidated

two different way

2:50 AM

it is not in this context

It could be actually

2:50 AM

as that value is being read from PC which could at any time become invalid

storing and checking one instruction after so if this happens I'd better uninstall the game now

2:51 AM

specially in non multi threaded game (edited)

OSubMarin

storing and checking one instruction after so if this happens I'd better uninstall the game now

If you're storing it locally prior to the next check, then no, it should not invalidate, but your code isn't any more optimized than simply rereading the pointer and compiling with -O3

2:52 AM

and the game is threaded, the threads are just clearly marked (rendering, game, etc.)

2:52 AM

the rendering thread runs entirely separate from the game update thread.

yep that's what I meant

2:52 AM

I prefer doing the O3 myself

2:53 AM

question of habbits I suppose

I disagree with trying to -O3 by hand. The hundreds of extremely experience developers and the 30+ years of Computer Science is always going to beat whatever optimizations I can make.

2:53 AM

especially since I don't know all x86_64 intrinsics (edited)

no I was talking about the additional function resolution and call times

2:55 AM

good to know the compiler does it on its own (edited)

2:59 AM

this is what I have:

3:00 AM

I don't have O3 anyway

3:00 AM

it's not in the dropdown menu

O3 is part of GCC and Clang (edited)

3:01 AM

MSVC doesn't really follow the same standardization that most compilers do with their flags.

MS following standardization ^^

3:02 AM

yeah, funny

3:02 AM

with all their fancy types all the time to reinvent the wheel

3:04 AM

I'm targetting Windows environment so the msvc should not be a problem tho

just spawn a particle emitter on the character's head.

Yes but this will not produce the shooting animation right?

What does the particle emitter allow? producing a sound and a flash light effect maybe?

this could be enough if so

3:25 AM

I'll have to check that thank you

Hello, I'm having troubles to remove all items of given type from player's inventory. Here is the code I made:

    if (inventory == nullptr)
        return false;

    // Get berrybush-seed class

        return false;
    TSubclassOf<UPrimalItem> bpSubClass = TSubclassOf<UPrimalItem>(bpUClass);

    // Get berrybush-seeds from inventory
    TArray<UPrimalItem*> berryBushSeedItems;
    inventory->FindAllItemsOfType(&berryBushSeedItems, bpSubClass, true, true, false, false, false, false, false);
    int nbBerryBushSeeds = (int)berryBushSeedItems.Num();

    }

    // Remove berrybush-seeds from inventory
    for (int i = 0; i < nbBerryBushSeeds; i++)
    {
        UPrimalItem* currentItem = berryBushSeedItems[i];
        if (currentItem != nullptr)
        {
            FItemNetInfo itemNetInfo;
            if (currentItem->GetItemNetInfo(&itemNetInfo, false) != nullptr)
            {
                FItemNetID itemNetId = itemNetInfo.ItemIDField();
                inventory->RemoveItem(&itemNetId, false, false, true, false);

                    UPrimalItem* currentItem = berryBushSeedItems[i];
                    if (currentItem != nullptr)
                        currentItem->OwnerInventoryField()->RemoveItem(&currentItem->ItemIDField(), false, false, true, true);

Hello, I'm trying to increase the period before someone gets auto-kick for being AFK on my servers. I added the -EnableIdlePlayerKick in command line arguments. The KickIdlePlayersPeriod is set to 3600. The problem is that AFK players are getting auto-kicked before reaching the 3600 seconds. Some people tried to increase the 3600 seconds value here without success: https://www.reddit.com/r/ARKone/comments/jmwr47/possible_workaround_for_30m_disconnect_change_the/ They say it's because the timer is client-side managed. They say that players need to restart their game in order to properly reset this timer. I will assume that what they is true, so I need to handle a timer on server side. I can setup stuff in the PostLogin function, but I have no idea of how I can get the number of seconds elapsed since last player action. (edited)

hook KickPlayer and check for the afk kick string

11:35 AM

that will tell you exactly when the server tried to kick the player

Good idea, but I still need to know when was the last action.

they probably store a field somewhere

Yep, still searching ^^

find KickPlayer

11:36 AM

press ctrl + x on it

11:36 AM

and it will show you refs to everything that calls it

11:37 AM

then find where it's called from with the afk string

11:37 AM

that will show you how they check that

Alright thanks for the methodology, will try it right now.

ah it might not be so easy

11:41 AM

i cannot find the string

11:41 AM

that you get when you're idle

WETBATMAN

i cannot find the string

Maybe because the guys on reddit are right and it's only client side?

I've started a text search for "idle" in IDA but it's running since few minutes now, I guess I will have too much results ^^ (edited)

12:01 PM

I can see a lot of function related to IdleMode, mostly linked to CVarIdleWhenNotForeground

12:03 PM

https://i.imgur.com/K7d9lhA.jpeg

12:07 PM

I found the string WETBATMAN

12:07 PM

It is used in this function :

12:12 PM

Not sure what do to with this info tho :/

why does it not show me this in strings lol

12:16 PM

this->LastMultiUseInteractionTime

12:16 PM

ah

12:16 PM

here

12:16 PM

this is where they store the last activity

IdleKickPseudoCode.cpp

9.33 KB

12:18 PM

you're right I can also see the

v79 = UWorld::TimeSince(v78, v655->LastMultiUseInteractionTime);
                    if ( v79 > v113 )
                    {

if ( UWorld::TimeSince(v32, this->LastLargeMoveTime) > v50
                || (v33 = this->GetWorld(this), UWorld::TimeSince(v33, this->LastNotOnUnriddenDinoTime) > v50) )
              {
                v34 = this->GetWorld(this);
                if ( UWorld::TimeSince(v34, this->LastMultiUseInteractionTime) > v50 )

12:18 PM

this seems to be the driver code behind the kick

Alright

12:19 PM

I think I can do something now

12:19 PM

Thanks for your help, will comeback when I have more details

np

I don't understand this variable name LastNotOnUnriddenDinoTime

12:35 PM

I suppose it's the last time the player went on/out of a dino? What a weird name ^^ (edited)

OSubMarin

I don't understand this variable name LastNotOnUnriddenDinoTime

i guess that means the last time player controlled a dino?

1:09 PM

so like passengers wouldn't count i guess

Ok, that's also what I thought. (edited)

Is there any way for us to access a character's explorer notes?

What do you mean by accessing? You want to list unlocked explorer notes or modify them?

9:44 AM

I'll have a look with IDA to see if I can find something. (edited)

OSubMarin

What do you mean by accessing? You want to list unlocked explorer notes or modify them?

Both actually, yes

And thank you, that would be awesome.

Apparently the explorer notes are stored in the player profile file. Do we have any access to that in the api?

I think that you need to modify an array in the player's profile (you don't need to modify the profile file itself).

Player profile might be primal player data, or the bytes array on the player data

5:35 PM

Nope, there's a UPrimalLocalProfile

5:35 PM

The most interesting parts of the class are these (not complete, it's too large to include here)

struct UPrimalLocalProfile : UObject
{
  TArray<TSubclassOf<UPrimalItem>,FDefaultAllocator> AchievementItemsCollectedList;
  TArray<FString,FDefaultAllocator> UnlockedAchievementsList;
  TArray<unsigned int,FDefaultAllocator> GlobalExplorerNoteUnlocks;
  TArray<FString,FDefaultAllocator> UnlockedAchievements;

  // ...
};

(edited)

5:37 PM

But by the looks of it and its variables it seems to be client side mostly?

If it's client side only then you could teleport the player on the explorer note for a second and teleport him back. Not a pretty solution but that could do the trick. (edited)

It would be useful for unlocking, but might not be the use case here

8:46 PM

I believe it was meant to be read and check if player has X explorer note most likely

1

maybe looking at the part that handles the "+10 levels if all explorer notes unlocked" could give additional insight (edited)

9:21 PM

that could be handled locally too, but because of anti cheats measures there's probably a way for the server to validate that. (edited)

9:22 PM

or maybe I just discovered a new cheat x)

Hello, I'm trying to get the points score when someone rides an HoverSail and make tricks. (edited)

It’s probably all blueprint

2:30 AM

The string is probably in the uasset

Thank you. I never played with blueprints/uassets yet tho. Does that mean that modifying the hoversail tricks behaviour cannot be done through Ark Server API? (edited)

2:38 AM

Actually I don't want to modify its behaviour, I just want to grab the trick-points to make an "hoversail points player ladder" ^^ (edited)

2:42 AM

Does someone has a good starting point for me to work with Ark blueprints/uassets (like a tutorial or some documentation link)? (edited)

I suggest downloading the devkit

5:24 AM

You can hook the event from a c++ function

I am trying to figure out how to serialize object inside the plugin, so far I found a few classes that have a serialize method like APrimalCharacter->Serialize(FArchive * Ar), but I did no find something to unSerialize

3:07 AM

should I try to use something like the boost lib, or there is a way to serialize/unserialize using what the Ark Api have?

lookin into boost and other serialization library's, looks like in c++ I have to provide my onw serializa/unserialize data

2:58 PM

that is so much work

@UacaUObjects have reflection info

iterate the properties and serialize that

I am using UKismetSystemLibrary::SphereOverlapActors_NEW to find structures nearby, it looks like it only works with player near the locations, is there any way to scan for structures without player near by?

I think you can try UVictoryCore::ServerOctreeOverlapActors

8:12 PM

thats what I use

8:13 PM

oh wait.. i think i read that wrong ha

8:15 PM

let me try again.. this should work i think UGameplayStatics::GetAllActorsOfClass

and for each position check if is in the Sphere?

this will get all stuctures in the world

c++
TArray<AActor*> FoundActors;
UGameplayStatics::GetAllActorsOfClass(ArkApi::GetApiUtils().GetWorld(), APrimalStructure::GetPrivateStaticClass(), &FoundActors);

8:17 PM

then you can just loop thru FoundActors

i see. Thank you!

Yep, I just came accross the same exact issue recently. Using Octrees works better. There's also an api utils function to get nearby actors. You should avoid Get all actors of class unless necessary, if you need actors in range use octrees (GAAOC hangs the server for a moment)

do you mean using ServerOctreeOverlapActors instead of SphereOverlapActors_NEW ?

Yes, it's more reliable for non rendered structures and it's also faster

will try, ty

Uaca

do you mean using ServerOctreeOverlapActors instead of SphereOverlapActors_NEW ?

Btw if you only need to know if a structure is within a sphere

9:38 PM

Just check the distance

9:38 PM

If sphere A is at point X and object B is at point Y

9:38 PM

Then distance(A,B) <= X.radius

9:38 PM

Then it is in the sphere

this if I already have the structure? right?

Yes

9:40 PM

If you know if structure B and have some point P and a known sphere radius R then Sphere A is obviously at P with radius R

9:40 PM

So if you know structure B you can do what I said above

i see

All points on the edge of the sphere are radius R from the center

9:40 PM

A sphere is just a 3D circle after all

it make sense

9:41 PM

ty!

One note!

9:41 PM

This will fail if the position of the structure is outside the radius

9:42 PM

So if it is a large object or near the edge it could fail

9:42 PM

You can adjust your radius by C where C is the size of the structure if you want to implement some fuzzy logic

9:43 PM

Basically if it is like 0.1 away from being inside … it probably is like 49% inside the sphere so a little leeway is ok

9:44 PM

You can calculate that exact amount given the look at vector between the sphere center, the object, and the object dimensions and rotation (if you want close to exact) (edited)

9:44 PM

But that is decently math heavy

9:45 PM

If your needs are that exact , use an overlap/octree

9:45 PM

It’s easier at that point

substitute

it is ark, you can’t be to exact or the player will think there is something wrong

ty for the tips!

I looks like there is 3 hooks for inventory dropped items:

UPrimalInventoryComponent_StaticDropNewItem UPrimalInventoryComponent_StaticDropNewItemWithInfo UPrimalInventoryComponent_StaticDropItem

Is there any advantage in using one over the other? I am just trying to know if the player dropped a fertilized egg

Hook them and find out!

4:20 AM

I'm not sure, though

Another approach is hooking ADroppedItem_BeginPlay or similar, and check the fields like dropped by player id, dropped by name (player name I guess), etc...

2:50 PM

FString & DroppedByNameField() { return *GetNativePointerField<FString*>(this, "ADroppedItem.DroppedByName"); }
unsigned __int64& DroppedByPlayerIDField() { return *GetNativePointerField<unsigned __int64*>(this, "ADroppedItem.DroppedByPlayerID"); }

2:51 PM

Each time an item is dropped, a new ADroppedItem actor is spawned I believe (edited)

Pelayori

the item is always empty

4:16 AM

is the item is dropped, will UPrimalInventoryComponent still have reference to the item? Because it was like already removed?

yeah, i used the dump from ark shop to check, the item is already out of the inventory

To add the arguments to the string add {} for each argument you want to output. You can put multiple times the same argument by using the arg's index: {0}, {1}, {2}, etc...

you aren't binding the params

5:06 PM

you're only binding the instance

5:06 PM

use std::placeholders

ty sm ill try it out asap (edited)

could you tell me how to do it correct, I tried std::bind(ChatListener::on_message_received( _1, _2, _3, _4,_5)) (edited)

5:55 PM

since yeah I am so lost

Are you trying to point to a member function?

BananaBread

could you tell me how to do it correct, I tried std::bind(ChatListener::on_message_received( _1, _2, _3, _4,_5)) (edited)

placeholders are params for the bind function, not your function

6:06 PM

also you aren't binding the instance here anymore

You can trick the compiler with like

6:07 PM

(*(void**) class::member)

binding instance nowstd::bind(this,ChatListener::on_message_received( _1, _2, _3, _4,_5));

But that’s highly not advised

BananaBread

binding instance nowstd::bind(this,ChatListener::on_message_received( _1, _2, _3, _4,_5));

remove params and pass them into std::bind instead

6:07 PM

not your function

6:08 PM

also instance goes after the function pointer

I’m not really sure why they are making a reference to a member function

6:08 PM

Without passing a reference to “this” it’ll just crash

std::bind(&ChatListener::on_message_received, this, placeholders...);

got this now AddOnChatMessageCallback(chatMessageCallbackID, std::bind(ChatListener::on_message_received,this, _1, _2, _3, _4, _5));

this should work but i would advise against using namespace std

6:10 PM

actually no

6:10 PM

that wont work

it wont yeah ^^

because you aren't passing a function pointer

nwo it does

you need & before function name

ye I did

6:10 PM

I am using std::placeholders as namespace

6:10 PM

should i just write out infront of the placeholders instead?

i would tbh

6:11 PM

personal preference thing though

6:11 PM

it doesn't really change anything other than code readability

thx alot, is there a ressource i can read up on this again to learn what i did here

6:11 PM

or could you explain in short

6:11 PM

i come from c#

6:11 PM

and there i can just pass a function

do you know what & before function name does?

or with events i can just += f

WETBATMAN

do you know what & before function name does?

yes

6:11 PM

well sorta

it's address of operator

6:12 PM

instead of passing function as value

6:12 PM

you pass it's address

yeah

6:12 PM

the pointer to a func right

this way it can invoke your callback from the provided address

6:12 PM

however

6:12 PM

since your function is a class member

6:12 PM

it uses the __thiscall calling convention

6:12 PM

so because of that you require a class instance

6:12 PM

with std::bind you bind the function to the instance you just passed

6:13 PM

and the placeholders act exactly like placeholders

my mate told me to just not use classes here and that makes it easy (make it static) but i think that is a wrong convention and bad code

once it calls the function params will be passed instead of placeholders

BananaBread

my mate told me to just not use classes here and that makes it easy (make it static) but i think that is a wrong convention and bad code

that's up to you

6:14 PM

i do the same tbh when making plugins i make classes for everything i use

WETBATMAN

and the placeholders act exactly like placeholders

this placeholder thing is new to me and confuses me a lil

WETBATMAN

i do the same tbh when making plugins i make classes for everything i use

i need the classes to follow SOLID, if not solid doesnt rly work

6:15 PM

but i might be wrong trying to use a c# principle in c++?

BananaBread

this placeholder thing is new to me and confuses me a lil

since your function takes parameters and you don't know what those parameters will be beforehand, you pass placeholders so when ArkApi invokes your callback it will pass arguments on runtime

ah nvm

what do you mean

nvm, that was a stupid thought

6:17 PM

its weird that i didnt find any resource to read up on this

6:18 PM

thx!

Could you tell me if there is a function to broadcast in the ark api?

broadcast what

a message

seems so simple, yet couldnt find it

Ty good sir!

11:45 PM

now i also know were more functions are hidden

They are the opposite of hidden though

well show me the wiki then <3 (edited)

11:53 PM

if i do click on wiki on the site, it do not work :D

The wiki is source code

it's just a click away! (edited)

that is true

is there anything i got to do extra so i can run my plugin? I followed the guide in the tutorial channel hwo to setup everything and just created a build. When starting the server it says plugin test does not exist. I tried looking up what the permissions plugin has what mine doesnt, so i added arktestplugin.ddl, arktestplugin.pdb & PluginInfo.json. Sorry for asking so much, i am just new to everything :/ (edited)

folder and dll name have to be the same

is that a usual convention and common to dll applications?

no

12:38 AM

every application on windows loads dll's

12:38 AM

but not every application has a folder with them

is there a resource where i couldve known / found this out myself? (edited)

ArkApi source code

okay, i realise i rly should go through it

dll's are loaded by path, infact that is exactly what ArkApi itself exploits and why it's called version.dll

12:40 AM

it's because all windows applications load version.dll into themselves automatically

12:40 AM

however if version.dll is present in the same folder as the .exe it has load priority over the one present inside the win32 folder

12:40 AM

this is called a proxy dll injection

and that is the reason we can inject the api before the server starts i guess? (edited)

BananaBread

and that is the reason we can inject the api before the server starts i guess? (edited)

it's loaded by windows very early during the server .exe startup

12:42 AM

ArkApi then proceeds to load the original version.dll file from the win32 folder and it creates jumps to all the proxy functions

12:43 AM

this way it still technically "contains" all functions from a legit version.dll

do you have any good resource to read up on this?

12:43 AM

like a book or an article

for proxy injection?

to understand what you just explained a lil better

12:44 AM

to get more used to in this area

for proxy injection?

if that is it, i guess ill just google on it

12:45 AM

here are some examples

12:46 AM

the concept is simple you make your dll look like some other dll

12:46 AM

like i said before windows loads it's dll's into every application in order for them to run

12:46 AM

you can proxy any of those

do you need this to bypass battle eye or something?

battleye detects this

12:47 AM

and no, it's simply used for just loading ArkApi

12:47 AM

(in this case)

12:48 AM

you can certainly bypass game anti cheats with this though

12:48 AM

i've tested it for league of legends and it works

why does wildcard not implement an own api for ark liek league of legends does etc

12:48 AM

why does some cool guy need to do all this effort with injecting

dunno

12:48 AM

devkit could easily have had c++ support too

I slowly think i shouldve first started with the dev kit since i come from c#

no

12:49 AM

heh

12:49 AM

it's trash

but i rly wanna expand my knowledge and kinda force myself with this to learn c++

devkit is trash you can't do half of what you can do with plugins

since they dont offer that many exposed functions to work with or how come? (edited)

you can't connect to a mysql database

12:50 AM

you can't override a function without your mod having to be loaded first

12:51 AM

you can't access certain functions which are just not available in devkit

12:51 AM

and if you compare the performance, a plugin doing exactly the same as something made in devkit is always gonna be faster

how did you start out with this? did you help developing the api

i started out with 0 programming knowledge

man that is crazy how far ya made it then

developer of ArkApi (Michidu) helped me alot

eventually i learned c++

good job dude

do you know a way to clean up the release folder (edited)

1:05 AM

so i can find the 2 files i need to pull over easier

1:06 AM

there is so much other things visual studio creates that is not needed

1:06 AM

like can i make vs put those 2 files in 1 folder

with a regular dll project there should be at most 4 files in your release folder

1:13 AM

it is not much ofc just annoying

that isn’t the output folder

1:13 AM

because there are object files inside

1:14 AM

the output folder should be inside project->X64->Release

that is the release folder

1:14 AM

i dont have an output folder in there (edited)

then something is misconfigured for sure

found out why / what

1:18 AM

so my output directory was just simply the release folder itself

1:18 AM

i now created a sub folder

1:18 AM

and set the output directory inside (edited)

1:18 AM

i hope that doesnt cause errors later

you can even output directly into the ArkApi folder and utilize the auto plugin reload feature

ill have a look into that

1:36 AM

thx!

1:38 AM

Could you tell me what i need to setup to load and unload a plugin runtime?

1:42 AM

mb

1:42 AM

just found it

If you rename your plugin: myplugin.dll to myplugin.dll.arkapi and drop it in your plugin folder when your server is running, it will detect that file and load it

on the official website

1:43 AM

oh that is crazy

BananaBread

i need the classes to follow SOLID, if not solid doesnt rly work

You can make static class methods that don’t require an instance of the class

Heya all! Not sure if this is the right channel. I've been working on an ARK plugin for the past 5-6 days. i got most of my code working for my chat commands. and saving data to mysql. I managed to get around pretty well. Pluign builds and loads fine in the server. Now i'm trying to get the main element of my plugin working. I setup some debug logging to text files to help me debug a bit. The hook generator app made by OwnProx isnt working. so i'm using the hardway lookin into the files I want to edit the behavior of the Floating Damage Text if my player /dn off that player will not see any Floating Damage Text and if my player /dn on he will see it. The hook that seems right for the job... would be DECLARE_HOOK(AShooterGameMode_NotifyDamage, void, AShooterGameMode*, AActor*, FDamageEvent*, AController*, AActor*); but after some testing... this hook is triggered even with no players on the server. if i try to obtain a steam_id inside that hook my ark server crashes. been loooking / testing on the hook part for the last 2 days... thought someone could point me in the right direction. This is my very first plugin... so its super simple... I'm hoping to get into a few bigger projects next. Thanks in advance!! Cheers.

The hook is the following:

7:19 PM

DECLARE_HOOK(AShooterPlayerController_ClientAddFloatingDamageText, void, AShooterPlayerController*, FVector_NetQuantize, int, int);
void  Hook_AShooterPlayerController_ClientAddFloatingDamageText(AShooterPlayerController* _this, FVector_NetQuantize AtLocation, int DamageAmount, int FromTeamID)

    {
        const uint64 steam_id = ArkApi::GetApiUtils().GetSteamIdFromController(_this);
        if (players_disabled.Contains(steam_id)) { return; }
    }

    AShooterPlayerController_ClientAddFloatingDamageText_original(_this, AtLocation, DamageAmount, FromTeamID);
}

I did that to implement it, when players do /dmg off it adds their steamid to players_disabled (TArray<uint64>) (edited)

ok sweet thank you very much

maybe instead of doing this send the floating text being set to off to players who switched it off?

ArkShop does this for beacons

Hello, apologies in advance for asking this insanely stupid question...but where do I learn more about getting started?

Understood.

anyone know why ArkShop doesnt give player's points. Everything is set and it has no errors when getting kits, buying stuff or even in server console. Somehow when players do /points there are no points. and no points given. I have an interval of 5 and 20 points

Hello guys, happy holidays. a question. How can I make a code for a bot for streamers notifications ?. I don't want to use a ready-made one, I would like to create my own. any help?

I've never messed with teleporting yet so please bear with me

But i'm trying to teleport from Location A to Location B and then back to Location A I record Location A before teleporting to Location B by using: shooterplayer_controller->RootComponentField()->RelativeLocationField(); But when I try to teleport back to Location A.. it's not the location I was expecting at all. Instead it's teleporting me back to my origin spawn point when I first joined the map.

‍♂️

show us your implementation please

in a nutshell this is what I'm doing:

c++
typedef std::map<uint64, FVector> SteamIdFVectorMap;
SteamIdFVectorMap lastPlayerLocation{};
...

// teleport from A to B
const FVector m1 = shooterplayer_controller->RootComponentField()->RelativeLocationField();
lastPlayerLocation.insert({ steam_id, m1 });
                                                                                
shooterplayer_controller->SetPlayerPos(newLoc.X, newLoc.Y, newLoc.Z);

...

// teleport back to A
if (lastPlayerLocation.size() > 0) 
{
    auto result = lastPlayerLocation.find(steam_id);
    if (result != lastPlayerLocation.end()) 
    {
        auto playerLoc = result->second;
        shooterplayer_controller->SetPlayerPos(playerLoc.X, playerLoc.Y, playerLoc.Z);
        lastPlayerLocation.erase({ steam_id });
    
    }
}

get the position from the character

6:52 PM

not the controller

@$%RYT@R#@!~

7:09 PM

hey that sounds like a good idea! lol

I think getting World Location of the actor is better than relativelocation.

what makes it better? and where is that called?

WETBATMAN

get the position from the character

Thank you it's working now using the character instead of the controller.. ugh why didnt I see that! lol

I believe world location is treated like an absolute position. Relative location can give varying results depending on what you are checking the position of since it is relative to some other factor. However for players it may not matter which is used but I believe world location will always be accurate.

FVector Location;
_this->RootComponentField()->GetWorldLocation(&Location);

2:00 AM

You could probably check and see what location coordinates match up with the ccc ones to make sure there is no difference between world or relative as well.

thank you , I appreciate the explanation, i will use that instead

also by the way, if you do not require the sorting property of std::map it's better to use std::unordered_map instead

Hey all! I'm a veteran software engineer but new to c++ and the ins and outs of the ark api. Ended up here because I couldn't see any other way to get our cluster work the way I'd like it to. Currently in the process of figuring out a hello world or how to test/debug what I'm doing

Got through the initial hurdle. Now the big question is: how do I figure out the correct hook to call? Been browsing the sources for hours but nothing screams at me. Is there a way to somehow step through execution with the ark dev kit to find what I'm looking for?

what is it that you're trying to do?

substitute

what is it that you're trying to do?

Trying to figure out how to stop the cross-ark functionality in supply drops (and not obelisks). Basically to replicate how the transfers work in single player. There is a mechanism somewhere in the code that tells the supply drops to not have the item/dino/player transfer options...

If anyone can point me to the correct hooks, that'd be much appreciated. The main motivation in this is to make sure our aberration server has the in-lore experience where the challenge is to get to an obelisk before you can yoink your transmitter out of the uploaded items tab and then you can enable your tribe to have access to all the op stuff you've built up before you got to aberration. If supply drops give you access to everything, there's little-to-none challenge in the map.

3:48 PM

Disabling the drops isn't an option because that also removes a good gameplay loop from the map; going to the surface to get good gear.

Check the UPrimalInventoryComponent of the supply crates if they have tribute properties set.

I've been digging around there. Unfortunately the tribute is for the boss arena teleports. I'm looking for 3 things: ArkData, Creature Data and the transfer to other servers buttons. I think there's a way to hook into the item/creature download process itself and cancel it. somehow. Not sure how to prevent the tabs from showing though

The buttons are going to be client side which you can't make hidden or anything.

5:12 PM

Some of the events you can intercept but handling of those may not be great and leave players locked in place until the client figures out the operation won't complete and shows a timeout error. But seems like you are on the right track.

It would still be better to find that one setting that makes the entire system think that it shouldn't display those buttons in the first place

99% sure that is client side only which you can't change from a plugin

Hi! Can somebody help me what is the best way to add multiple stacks(for example 201 stone) of items to an inventory? Should I make a for a loop?

I’m sure there’s a more accurate function

However you can also get the capsule half height and subtract that to the z calculation

    FVector offsetDown = FVector(0.0F, 0.0F, -5000.0F);
    return shooterCharacter->GetGroundLocation(outGroundLocation, &offsetUp, &offsetDown);

And if you're not dealing with an APrimalCharacter, you can simply use the one from UVictoryCore namespace. Instead of an APrimalCharacter it needs a pointer to the UWorld and an FVector starting point (then it will search upside and downside for the ground, starting from this point). (edited)

Is there a simple way to scale one specific dino (I can find the APrimalCharacter with the dino ID) permanently? (edited)

To make it bigger you mean?

yes

7:48 PM

I was thinking of something like this:

void ScaleActor(AActor* actor, float ratio)
{
    FVector currentScale;
    actor->GetActorScale3D(&currentScale);
    currentScale.X = currentScale.X * ratio;
    currentScale.Y = currentScale.Y * ratio;
    currentScale.Z = currentScale.Z * ratio;
    actor->SetActorScale3D(&currentScale);
}

But I don't know if it's the proper way to do it because I'm not even replicating state over network here. (edited)

Yeah, it does not work

7:53 PM

Server will be aware, but client won't, and weird collisions and rubberbanding will happen

7:53 PM

Already tested it awhile ago

I will keep searching with ida, hopefully I'll find something.

8:01 PM

Did you try calling actor->ForceReplicateNow(false, false); after scaling actor @Pelayori?

Scale is not replicated, that will do nothing

Ok thanks

But I think I tried

8:02 PM

just in case lol

^^

8:04 PM

For scaling, you also have to make sure that on your Mesh Component you set "Component Replicates" https://answers.unrealengine.com/questions/375098/actor-scale-not-replicating.html (edited)

8:05 PM

I need a way to grab Mesh Component then

8:12 PM

8:13 PM

but it's already ticked on Dodo character BP

That's the status comp

8:13 PM

Not the mesh comp

ah

8:13 PM

my bad

If changing that bool works at runtime it's great

8:14 PM

the property is missing on Mesh element so I'm not sure what they mean by Mesh Component

hoho...

8:37 PM

this doesn't look good, otherwise I can't find an easy "Replicate Transform" checkbox x)

hey I managed to effectively scale the model at runtime for both server and clients (edited)

10:04 PM

Wrong code removed here, see below (edited)

10:07 PM

I tested it on a simple object with one SkeletalMesh. You need to adjust the meshComponentName parameter to target another type of mesh. Also my function stops when first mesh is found but for more complex objects you might need to repeat the SetIsReplicated(true) for every mesh component.

Interesting

10:09 PM

Good find

10:09 PM

I might yoink that some time monocle

got the explanation from UE documentation

10:11 PM

OSubMarin

hey I managed to effectively scale the model at runtime for both server and clients (edited)

nice!

I think that is why I could not a find a "Enable Replication" checkbox on the devkit (edited)

10:14 PM

because it's a function (SetIsReplicated(true)) not a property

10:15 PM

well I don't know exactly I don't care that much anymore x)

There will be some downside of setting extra replicated components though, not sure how much network overhead will add

10:17 PM

Not if you do it for a single actor, but if you do it for multiple ones

no worries I'm making targetted changes

10:18 PM

just few actors controlled by ID

1

10:23 PM

I will make some tests on a dino familly now, to see if it's not too big to track more meshes (edited)

10:24 PM

I forgot I closed the devkit, and I need it to grab every meshes that composes the dino (or at least the main one if there's a hierarchy in the model). (edited)

10:24 PM

well that will be another time

10:27 PM

on my screenshot above I notice dodo only has one mesh so hopefully it's like this for every dino and a single mesh component has to be targeted each time.

"I forgot I closed the devkit" ~ what!!? you don't want to wait 2 hours for it to open again? 2236_keka

I think it only works for skeletal meshes, trying to scale some static meshes and there is no success

sorry

11:05 PM

I mistaken some tests...

11:05 PM

the above function does not work

11:05 PM

it's actually the previous test I did which worked

11:06 PM

bool EnableMeshCompReplicationAndScale(AActor* actor, float ratio)
{
    USceneComponent* sceneComp = actor->RootComponentField();
    if (sceneComp == nullptr)
        return false;
    sceneComp->SetIsReplicated(true);
    sceneComp->SetWorldScale3D(FVector(ratio, ratio, ratio));
    return true;
}

There you go

11:06 PM

this works

just double tested this time

Oh, I thought the root component was already replicated

On the object I tried to scale it seems not (because after doing this it works) (edited)

11:07 PM

I didn't try on a dino yet

there is a ChangeSize admin command

11:10 PM

https://arkids.net/command/changesize

Ark ChangeSize Command | Ark IDs

Detailed information about the Ark command ChangeSize for all platforms, including PC, XBOX and PS4. Includes examples, argument explanation and an easy-to-use command builder. This command will change your character's size. A multiplier of 2 would double your size, 0.5 would half it.

11:10 PM

probably could find that in ida and see what they do

‍♂️

It's for characters, sets the capsule size (which is probably replicated by default)

OSubMarin

bool EnableMeshCompReplicationAndScale(AActor* actor, float ratio)
{
    USceneComponent* sceneComp = actor->RootComponentField();
    if (sceneComp == nullptr)
        return false;
    sceneComp->SetIsReplicated(true);
    sceneComp->SetWorldScale3D(FVector(ratio, ratio, ratio));
    return true;
}

There you go

Trying to do it on a tek shield (for safezones plugin) and does not seem to work unfortunately

ok

11:23 PM

is your tek shield actor replicated itself @Pelayori?

Uhm im not sure now

because the actor itself needs to replicate otherwise replicating components cannot work

11:24 PM

to replicate actor: AActor* actor->SetReplicates(true);

I think it is yes, it's a structure and has replicated properties

11:24 PM

but will give that a wirl

11:25 PM

Yeah it's the same

then I don't know

11:25 PM

it works on the pirate treasure box (edited)

No idea

Does some weird stuff on dinos.

it works!

No longer walks on the ground

yeah because the volumes are a bit buggy from scratch so it amplifies problems

11:28 PM

well

11:28 PM

might screw up from too much physics point of view (edited)

Dodo seemed ok at 4x

a good workaround would be to scale only the mesh part

11:29 PM

because the scene component is more a global object that regroups everything

11:30 PM

so the physics would remain the same (with the downside of being able to go through dino like in ghost mode since physics isn't touched and the model only appears bigger) (edited)

11:31 PM

or find ratios that don't screw too much with the physic volumes like you've started to do :p (edited)

I'll play with it a bit more and see.

11:36 PM

Dodo looks good at 4x

1

11:37 PM

It doesn't move fast enough for its giant legs though

xD

11:43 PM

Changed speed modifiers to match the scale modifier.

11:43 PM

might be too much though

that big boi is fast!

11:48 PM

maybe make a gun to adjust size in game (primary attack => zoom x1.5, secondary attack => dezoom x-1.5), but that would require client side changes most probably (edited)

Lethal

Changed speed modifiers to match the scale modifier.

could maybe change the speed stat

11:48 PM

which does properly adjust animations iirc

I'm testing speed ratios

11:56 PM

with this size you can now also increase the meat and hide it gives

I know it's giving @Lethal some ideas for Server Events or Lethal Sightings.. lol find the Giant Dodo!

nice!

In my json config, i'm allowing for dynamic values to some of my settings. Meaning they can enter a number, string or and Array (of ints) as value and the plugin will figure it out. I have it working and I am now reviewing my code and wondering if there is a better way to do this without try/catch

for (auto group_iter = groups_map.begin(); group_iter != groups_map.end(); ++group_iter)
{                                    
    std::string strFoundValue{};
    int intFoundValue{};
    std::vector<int> arrIntFoundValue{};

    try
    {
        auto foundValue = group_iter.value().value("SomeSetting", "");
        strFoundValue = foundValue;
    }
    catch (const std::exception&)
    {
        try
        {
            auto foundValue = group_iter.value().value("SomeSetting", -1);
            intFoundValue = foundValue;
        }
        catch (const std::exception&)
        {
            try
            {
                auto foundValue = group_iter.value().value("SomeSetting", std::vector<int>{});
                arrIntFoundValue = foundValue;
            }
            catch (const std::exception&)
            {
            }
        }
    }    

    if (!(strFoundValue == "")) {
        // string was found
    }
    else if (intFoundValue >= 0) {
        // int was found
    }
    else if (arrIntFoundValue.size() > 0) {
        // array was found
    }
}

any feedback is appreciated

(edited)

json objects have methods for that

9:31 PM

search is_string, is_whateveryouneed

‍♂️

for numbers you have is number (int or float I believe), is float

9:32 PM

for arrays, is_array

oooh so like... bool bIsArray = group_iter.value()["SomeSetting"].is_array(); (edited)

9:34 PM

thank you!

yeah, like if is array do a thing, else if is number do another...

Pelayori

yeah, like if is array do a thing, else if is number do another...

use FVector::Distance()

you can also use GetDistanceTo from one actor to another

is there somewhere i can see what each code means or all they just magic numbers when my plugin fails to load

they're LoadLibrary error codes (edited)

6:00 PM

lmao

it means your plugin threw something inside DLLMain and couldn't load

yep

6:02 PM

i know how to fix this

GetGameState is not going to be ready on dll load

ah

6:03 PM

ty lol

because the GameState is not loaded yet

explains why it loads fine after initial crash

also chat command verify is going to listen for verify

6:03 PM

not /verify

6:03 PM

if you wish it to be /verify the string needs to be /verify

gotcha

6:04 PM

ty

Also if you are init'ing log you can use the logging funcs

for the unreal engine http stuff, why isnt there a method called OnProcessRequestComplete in the api but on unreals docs there is https://docs.unrealengine.com/4.26/en-US/API/Runtime/HTTP/Interfaces/IHttpRequest/OnProcessRequestComplete/

IHttpRequest::OnProcessRequestComplete

Delegate called when the request is complete. See FHttpRequestCompleteDelegate

8:40 PM

in the ark server api

8:41 PM

basically im trying to do a GET request and read the header contents of the response

You are better off using the api requests

8:42 PM

they are using POCO lib

i tried but kept getting 400 error

#include "Requests.h"

8:42 PM

That's not issue of the library

ill set it back up and show you what ive got

8:47 PM

ah the issue was that i had spaces in one of my parameters

8:47 PM

works in postman but not in the api

8:48 PM

the api says the response given in the callback shows headers as well but when i print it i get nothing?

8:48 PM

not sure then, @WETBATMAN would be the one to answer (edited)

void VerifyCallback(bool success, std::string response) {
    if (!success) {
        Log::GetLog()->error("Failed verifying with server.");
    }
    Log::GetLog()->info(response);
}

void VerifyCommand(AShooterPlayerController* playerController, FString* command, EChatSendMode::Type chatType) {
    uint64 steamID = ArkApi::GetApiUtils().GetSteamIdFromController(playerController);
    std::string url = "http://localhost:6100/?steam64id=" + std::to_string(steamID) + "&arkid=Ragnarok-PF"; // +ArkApi::GetApiUtils().GetGameState()->ServerSessionNameField().ToString();
    
    API::Requests::Get().CreateGetRequest(url, &VerifyCallback);
}

headers are not returned in the callback atm

8:50 PM

it only returns the response as std::string

Is there a way to get to the headers?

not currently, it would require an update for ArkApi

big brain moment

8:57 PM

good enough for me lol

?

8:59 PM

it provides status code on failure

i can put data in the status description

you can do this with default requests too

i just picked bad request

9:01 PM

if i give it the OK then it doesnt print anything in the response

I use my own webserver and return json reponses in response body

so I just load json from std string response

oh duh

9:03 PM

i kept looking for something called body in the C# HttpResponse

9:03 PM

its called outputstream

oh lol

9:04 PM

yup thats way better ty

Where's the ArkApi documentation? Developers Wiki link is dead

In the source code only now I believe.

I have never used any .json files... I am wondering if someone would have the time this weekend to help me set these up for my server cluster? I am completely new to this type of file, and would much appreciate any help received... I am able to find them for each plugin I am using, but I have no clue on what to change, what not to change, how to change it, etc...

they are used to configure your plugin.. usually there's a copy with comments explaining what each setting does, or they are explained on the arkapi webpage

I did look on the website, however I am finding it hard to find the explanations/or copy with comments... I am willing to work with someone who knows & hopefully understands these files... I should also mention that I have a generalized learning disability that makes it hard for me to figure things out at times... this is the reason why I am asking for help... (edited)

4:25 AM

Good night, and I will check in tomorrow...

Is there anyone who has the time to help me configure the json files for my servers?

I'm sure lots of people are willing to help, if you have an specific issue just post it on the plugin's discord server, or if said plugin doesn't have a discord server ask it on the general discussion channels. Alternatively you can also use #【📠】ᴄᴏɴꜰɪɢꜱ-ʙ channels

i did try to spaw a box and use it as DepositStructureResult, it also does not work. on the DropInventoryDeposit, if i try to bForceDrop = true it crashes the server

4:37 AM

the only thing left I can think of is to loop the inventory and remove the itens/add one by one

4:37 AM

somehow I think that will be slow

I had a similar experience with DropInventoryDeposit and was unable to get it to work, which is why I assumed you had to remove them manually

2:44 PM

Anyway, after a few hours of sleep, i found out how to do it:

`inventory->DropInventoryDeposit(ArkApi::GetApiUtils().GetWorld()->TimeSecondsField() + 3600, false, false, nullptr, nullptr, nullptr, nullptr, FString(""), FString(""), -1, 300, false, -1, false, nullptr, false);

a few times when i asked for help here, somehow a few kind souls shared code from the game and used IDA to extract this code

2:52 PM

I was unable to do the same

the way you wrote that was confusing lol, i thought you were trying to decompile a plugin

2:53 PM

but if you find the function by name in IDA you can click ctrl + x to see where it’s called from

2:54 PM

this way you can find out how the devs call the function

no need for the plugins, the source code is on github

WETBATMAN

but if you find the function by name in IDA you can click ctrl + x to see where it’s called from

but what do I chose to decompile on IDA?

hm?

do I use the ShooterGameServer.exe? It looked like ASM to me, there was no source code on IDA

you have to press yes when it asks to load pdb

2:57 PM

this way variables and functions will have names

2:57 PM

and yes, you need yo input ShooterGameServer.exe

i see, will try. Thank you !

Uaca

is this like a transfer all? do i have to create the bag and transfer all items passing the point to DepositStructureResult?

The deposit structure is a double pointer (pointer to pointer), and it's likely to let you access the spawned bag after it's been dropped

4:30 PM

So like:

void dropAll(UPrimalInventoryComponent* inv)
{
  if (inv)
  {
    APrimalStructureItemContainer* deathCache = nullptr;
    inv->DropInventoryDeposit(ArkApi::GetApiUtils().GetWorld()->TimeSecondsField() + 3600, false, false, nullptr, nullptr, &deathCache, nullptr, FString(""), FString(""), -1, 300, false, -1, false, nullptr, false);

    if (deathCache)
    {
      // do stuff with the death cache
    }
  }
}

i am trying to use a web hook to discord so far it works but when i reach 200 characters (limit of the chat) it will crash. I saw online that a discord web hook support 2000. i tried using a catch but didn't stop the crash. i took the webhook from the ArkShop Plugin.

i don't know what using a catch in that case is going to achieve?

9:16 AM

the 2000 char limit is a discord API limitation, you cannot send messages over this chat limit

9:16 AM

you have to split stings into sizes that are < 2000

also sending a webhook over 2000 chars won't crash, it just won't send to discord, if it crashes you messed something up in your code

secondly i don't know why you're converting an FString into a c style string and then into a wstring

9:49 AM

makes no sense, you're just wasting cpu cycles

9:50 AM

and also you should use API requests instead of game requests if you're going to be sending messages this often

9:52 AM

nlohmann::json request;
    FString MapName = GetMapName();
    request["username"] = ArkApi::Tools::Utf8Encode(*MapName);
    request["content"] = ArkApi::Tools::Utf8Encode(*Data);

9:52 AM

you can do something like this

9:52 AM

with Data being your final string ofc

9:52 AM

in this case it's FString

9:53 AM

void PostDiscordWebhook(FString URL, nlohmann::json Content)
{
    if (!URL.IsEmpty())
        API::Requests::Get().CreatePostRequest(URL.ToString(), [](bool Sucess, std::string Result) {}, Content.dump(), "application/json");
}

9:53 AM

this is how i send a request in my plugin

Ok thanks Wetbatman i will look into this today somewhere when i have time between work

using API requests you can get the response from discord API, which you can't really do with the requests you're using right now

9:55 AM

this way you can pinpoint your issue if you still encounter a problem after using this approach

9:59 AM

also when sending user messages to discord make sure to remove the @ sign

9:59 AM

(if any)

9:59 AM

if (Data.Contains(L"@"))
        Data = Data.Replace(L"@", L"");

9:59 AM

with something like this

9:59 AM

this is just so ppl can't tag everyone

What include should i use for API::Requests ?

Requests.h

WETBATMAN

Requests.h

Got it working thank you Wetbatman

How can I prevent / stop drop all items on fast travel? I can't find the hook to do this (sorry if too simple, i'm newbie)

i think ServerRequestFastTravelToPoint_Implementation just calls DropInventoryDeposit on InventoryComponent at some point in the function

10:14 PM

the playercharacter is destroyed though when someone fast travels, so the inventory items will vanish anyway unless u save them and re-add them back or something (edited)

I updated github fixing an issue from the last ATLAS change that broke ARK compilation. You should look at the open source plugins for examples as well. https://github.com/Michidu/Ark-Server-Plugins

Hello, I'm trying to make a player invisible from wild dino's (like the way leavemealone works). And I thought EnemyInVisible would do the trick, but it doesn't seem to work for me...

‍♂️

c++
shooterplayer_controller->EnemyInVisible(true);

7:26 PM

oh i just noticed there is also

c++
shooterplayer_controller->LeaveMeAlone();

i havent tested yet

7:26 PM

but how to turn it back on i wonder

7:29 PM

update: shooterplayer_controller->LeaveMeAlone(); did not work

welp, I found AShooterCharacter::bCanBeDamaged.. that's helpful

LeaveMeAlone calls several cheat commands! bCanBeDamaged could be an option but also overwritten by other functions you could use the damage hook event and just return 0 damage for every case from wild (edited)

what should i use if i want to add items to a structure ?

ingame structure?

9:39 PM

a c++ struct or an actual structure you place?

a structure i placed down auto* primal_structure = static_cast<APrimalStructure*>(new_actor); primal_structure->TargetingTeamField() = tribe;

Does anyone know of there is a hook called when a player equips/removes a shoulder pet?

Or do I need to use Hook_APrimalCharacter_TryMultiUse?

Echo! (Echo...Echo...Echo...Echo...Echo...Echo...)

So I been trying to prevent flying with the Sinomacrops, and there are two buffs that the player gets when the Sinomacrops is mounted: Blueprint'/Game/LostIsland/Dinos/Sinomacrops/Buff_Glider_Sino.Buff_Glider_Sino' Blueprint'/Game/LostIsland/Dinos/Sinomacrops/Buff_MountedSino.Buff_MountedSino' I can remove the Buff_MountedSino buff, but it seems that Buff_Glider_Sino will not remove, and as a result, you can still fly around. Okay, maybe I can prevent the Pick Up command from TryMultiUse... nope.. Ultimately I was able to use the APrimalCharacter_DinoMountOnMe hook to prevent mounting the Sinomacrops from the get go! It's not what I wanted, but it works.

8:36 PM

the NextAllowedMatingTimeField on the genesis 2 map does not look right

    FVector offsetDown = FVector(0.0F, 0.0F, -5000.0F);
    return shooterCharacter->GetGroundLocation(outGroundLocation, &offsetUp, &offsetDown);
}

(edited)

I keep trying to use this, but it only crashes for me

ShooterGameServer.exe!APrimalCharacter::GetGroundLocation() (0x00007ff7126f7a01) + 62 bytes [f:\build\lostisland\projects\shootergame\source\shootergame\private\primalcharacter.cpp:8125]

could you share a working example code snippet?

thx

There is another function, it does not require a character:

FVector GetGroundLocation(FVector* startLoc)
{
    FVector result(0);

    auto* world = ArkApi::GetApiUtils().GetWorld();
    if (world) {
        FVector offsetUp = { 0, 0, 0 };
        FVector offsetDown = { 0, 0, INT_MIN };
        UVictoryCore::GetGroundLocation(world, &result, startLoc, &offsetUp, &offsetDown);
    }

    return result;
}

What's the admin command to load/unload a plugin ? (can't find the faq thread anymore :/)

8:41 PM

Ok, i found in the source code, it's plugins.load

I am less than a novice, but I want to make a specific API... Is there anyone who could help me out by teaching me?

I am looking for some help - I was just told that plugins & API's are made only using unreal engine and C++, but most of them have .json files, and I am looking to make one to keep items and be able to use them when Transferring from one server (i.e. pve) to another server (i.e. RP) even if the engrams are locked on the 2nd server, essentially, taking the Player Data and the Item Data for that player from one server that allows all engrams to the other server that has Engrams locked behind certain permissions, but allow them to keep what they have learned/made no matter what... I wanted to make a JSON script for it, but altho I have the necessary information, I need help in actually writing it out... I am using Visual Studio Code as the program to help write it all out...

Plugins are written in c++ The JSON files are just your custom configuration files used to setup your plugins.

12:46 AM

The task you are trying to accomplish is a complicated one. I would focus on learning the basics of plugin development first, before you try to tackle that idea.

Dang, ok, welp thanks anyways...

Hello, does anyone knows which are the associated states for doors ? APrimalStructureDoor::GotoDoorState(this, X); with X being 0, 1 or 2, but I don't know if 0 = closed, 1 = open and why is there even a 2 there ^^ (edited)

2:18 PM

I'll test that at some point anyway but if anyone knows the answer that would be great

0 is closed, 1/2 are both open

But each state is open to a different side

ah for inwards and backwards

Yah

awesome thank you

Hello, is there a way to prevent cryopod usage for a given player? I was able to prevent putting dino in cryopod thanks to CanCryo() hooking but I don't find any interesting function for releasing from cryopod (unable to find a function like "CanUncryo()"). (edited)

For release you don't have a C++ function

4:11 PM

There's TryDeploy in blueprint, which can return a bool for success or not. But that needs process event hooking

I'm not sure what is process event hooking

void Hook_UObject_ProcessEvent(UObject* _this, UFunction* Function, void* Params)

4:12 PM

Basically hooking the c++ function that runs almost all bp functions

ouch x)

4:12 PM

not very optimisation friendly so I'll have to pay double attention to hooking code

That's like the most direct solution, others would rely on spawn from dino data

4:14 PM

Oh actually, you could hook SpawnFromDinoDataEx and it should have a valid PC on TamerController parameter

and you think SpawnFromDinoDataEx is not too late in the chain?

4:15 PM

how am I supposed to abort cryo release

Spawn from dino data is what spawns the dino, if it fails cryopod is not erased

4:15 PM

Detecting if cryopod dino, another challenge

hmmm so I just make a return whatever;

4:15 PM

ah

4:17 PM

so if I setup the hook Hook_UObject_ProcessEvent(UObject* _this, UFunction* Function, void* Params) how do I know if it's a TryDeploy() invocation? and eventually get parameters because a void* is not very helpful ^^

For parameters you gotta use devkit for easy finding

ok

The function's name field has the function name

4:18 PM

so Function->NameField().ToString().Equals("TryDeploy")

awesome

4:18 PM

I'll open the devkit and check the tryDeploy params in bp

4:18 PM

thank you

Could also cache the function's id by having a global int for Function->InternalIndexField(), much more efficient than doing string compares

ok I didn't know this trick thanks

Yeah, the internal index of a function won't change during runtime, that way you dont have to run a string comparison every time, which is like hundreds a second

(edited)

yes the runtime is why I try to avoid storing pointers x) (edited)

Try using AShooterCharacter::OnWeaponEquipped

Good idea thank you

Lethal

Try using AShooterCharacter::OnWeaponEquipped

how do you know if it's an equipped cryopod? with AShooterWeapon* NewWeapon->AssociatedPrimalItemField() and checking the class of returned UPrimalItem*?

(edited)

Yes

ok thank you

Ok I can get if it's an equipped crypod but don't know how to force removal of equipped cryo now ^^

5:25 PM

I guess I'll give a try at

APrimalDinoCharacter* Hook_APrimalDinoCharacter_SpawnFromDinoDataEx(APrimalDinoCharacter* _this, FARKDinoData* InDinoData, UWorld* InWorld, FVector* AtLocation, FRotator* AtRotation, bool* dupedDino, int ForTeam, bool bGenerateNewDinoID, AShooterPlayerController* TamerController, bool beginPlay)
{
    if (TamerController != nullptr)
    {
        if (!IsAllowedToCryo(TamerController)) // This function is mine but you can guess what it does.
            return nullptr;
    }
    return APrimalDinoCharacter_SpawnFromDinoDataEx_original(_this, InDinoData, InWorld, AtLocation, AtRotation, dupedDino, ForTeam, bGenerateNewDinoID, TamerController, beginPlay);
}

like Pelayori suggested (edited)

NewWeapon->StartUnequip();

thanks again

Just a heads up with that SpawnFromDinoDataEx() function. The definition for it in Actor.h uses "APrimalDinoCharacter.SpawnFromDinoData" instead of "APrimalDinoCharacter.SpawnFromDinoDataEx". I learned the hard way that calling APrimalDinoCharacter::SpawnFromDinoDataEx() from your own code gets ugly. Easy to fix if you need it. Don't think it matters if you're just hooking it the normal way.

I'm trying to figure out if a TekCloningChamber is currently active and cloning a dino.. I found this in the Dev Kit.. But I'm not sure where this variable is bIsCloning or how to get to it (edited)

Likely a bp variable

can i read bp variables? just like functions? if found

could do like:

UProperty* bIsCloningProp = CloningChamber->FindProperty(FName("bIsCloning", EFindName::FNAME_Add));
if (bIsCloningProp)
{
  bool bIsCloning = bIsCloningProp->Get<bool>(CloningChamber); // variable value
}

perfect.. I will give it a try.. thank you

That snippet works for any bp variable, as long as you know its type

1

Follow up.. It looks like the TekCloningChamber uses FARKDinoData to create the new dino. Is there some way of telling what kind of dino is being cloned from the DinoClass variable?

Get its bp path / get its default object and extract some variables / use DinoName variable (Dino_Character_BP_C format)

thank you .. i will look into that

7:30 PM

hmm i crashed trying to get the FARKDinoData from the blueprint.. does this look right?

7:30 PM

7:31 PM

but it must be stored somewhere before that

            {
                path_name = "Blueprint'" + path_name.Mid(find_index + 1,
                    path_name.Len() - (find_index + (path_name.EndsWith(

                        ? 3
                        : 1))) + "'";
                return path_name.Replace(L"Default__", L"", ESearchCase::CaseSensitive);
            }
        }

        return FString("");
    }

10:34 PM

Did you debug and set a breakpoint to make sure you were getting data back etc?

also seems the struct changed

struct FARKDinoData
{
    UClass* DinoClass;
    TArray<unsigned char> DinoData;
    FString DinoNameInMap;
    FString DinoName;
    bool bNetInfoFromClient;
};

Okay with the correct structure, it's now working and I am getting data. Thank you.

i'm trying to remove cryosickness from a dino and wake it up without using the cheatmanager The following code works, however, when I cryopod the dino again and throw him out (while there is a cryosockness timer still running) It behaves properly and is under cryosickness, but seems to skip the sleeping stage (eg. it still has cryosickness while standing up). so when i try to use this command again, it wont work, because the dino is not sleeping when it really should be. Once the timer is up, it behaves normally again. Any clues as to what piece I might be missing?

c++
    // make sure dino is asleep first 
    if (dino->bIsSleeping()())
    {            
        dino->SetSleeping(false, false);  // this seems to wake the dino up from sleeping
        
                // remove cryo buff from dino
        FString classString = L"Blueprint'/Game/Extinction/CoreBlueprints/Buffs/Buff_SummoningSickness.Buff_SummoningSickness'";
        UClass* classObj = UVictoryCore::BPLoadClass(&classString);
        if (dino != nullptr && classObj != nullptr)

dino standing with cryosickness after throwing him out of the cryopod again after waking him up the the above code (edited)

ArkApi::GetApiUtils().GetShooterGameMode()->ActiveEventField().ToString() gives me "None" for some reason (I have Easter event enabled tho), any idea why? I'm calling this just after AShooterGameMode_InitGame_original().

Solved, I had to wait for GameState to be ready and use GetGameState()->ActiveEventField() instead of GetShooterGameMode()->ActiveEventField().

Hey guys, I have a odd question, I am not even sure if its possible even with api, is there a way to block users from seeing certain maps when they open a transmitter to transfer? perhaps based on permission?

I don't think that is possible. You can certainly auto kick players when they join an invalid map. (edited)

Yeah I have a map like that, just looking for a way to prevent them from going. Tried through mod and found no solution either.

Looks like using console commands is a good way to send information, but is that really a good idea for a list of 40+ items at once?

You're talking about a plugin sending data to a mod?

yes, sorry was at work.

Xeakial

yes, sorry was at work.

is it your mod?

Yes it is my own mod

Xeakial

Yes it is my own mod

make a function that takes the data and then in the plugin invoke the function with your data directly

1:51 AM

it will be the most optimal

so your saying I can make a function in the mod and invoke it with an api? That is pretty amazing I was not sure if it had that capabilities, but that was the exact answer I was looking for, thank you!

Xeakial

Yes, with a little trickery

2:03 AM

you need to make sure you know the exact name of your function in the mod (the UFunction)

2:04 AM

and then you can take the instance of whatever the function is on and find the UFunction with findfunction and then you can call it with UFunction->ProcessEvent

2:04 AM

for the args, they (and return values) are passed as a structure

2:04 AM

but you pass them as void*

2:04 AM

so you need to define a structure for the parameters, and then do something like

2:05 AM

UFunction->ProcessEvent(this,func,(void*) args)

2:05 AM

you'll have to do a little legwork though -- it's been a little bit since I've worked with it.

Thank you, any point in the right direction is good. I am not new to coding, but have always actively stayed away from c++ whenever possible as its just to me not the fastest way to achieve the outcome I am looking for, but in this case it seems as I really don't have any other choices. I am sure I will be back with more questions.

I have searched around here for the answer I am looking for, can I use the standard oracle MySQL lib to incorporate database usage into my plugin? Or should I be using something else?

I use the same connector in other c++ projects and it works fine for all of them even with c++17, just does not compile with the api.

Xeakial

I use the same connector in other c++ projects and it works fine for all of them even with c++17, just does not compile with the api.

Check your C++ version

5:46 AM

For your project

I am using vs2019 with c++17 as c++20 did not get introduced until 2020 I believe it was.

Do i maybe need to go back a couple of versions of the connector? perhaps the new on is for the newest VS

solution was to go back to a earlier version. Now would I be better to build the source as a static library? or just put the dll files into the folder with the api to run connector8 ? so far I put the dll's in with the api and it seems to work just fine.

1:48 AM

Id rather not deal with cmake if possible, but If I have to, so be it.

is there a flag on AShooterPlayerController that shows is the player is fighting or do I have to hook the takedamage and do my own version of it?

I believe you answered your own question

I was so hoping not to have to make my own

Is it possible to remove creative mode buff in this fashion?

        FString classbp = "Buff_CreativeModeHelper_C_0";
                TArray<APrimalBuff*> p_buffs;
        AShooterCharacter* Cplayer = static_cast<AShooterCharacter*>(player->CharacterField());
        Cplayer->GetAllBuffs(&p_buffs);
        for (APrimalBuff* buffs : p_buffs)
        {
            const FString BP_buffs = ArkApi::GetApiUtils().GetBlueprint(buffs);
            if (BP_buffs.Contains(classbp))
            {
                buffs->Destroy(true, false);
            }
        }

You want to use this but I think what you have should work. FString classbp = "Buff_CreativeModeHelper"; (edited)

works perfect now, thank you!

I am able to connect to mysql when the database is on the same machine, when I use IP to another machine, always fails. I remember seen somewhere that it was not possible connect to a database on another machine. Is this true?

It's possible, I use the network name though, but it should work with IP too.. do you have a firewall? (edited)

It definitely works with IP, I use it from multiple machines through plugins and a discord bot that are all hosted on different machines from different locations. It has to be a firewall issue.

That or their sql server is either: bound to 127.0.0.1 instead of 0.0.0.0 Or Their login isn’t authenticated for their ip or %

Is this value somewhere in the API? I'm trying to find it...

1:50 AM

I found it at ArkApi::GetApiUtils().GetShooterGameMode()->MaxTamedDinosField();

is API::Timer::Get().DelayExecute(&handleplayer, 5, player) asynchronous by default? or do we have to do something extra to use it on a separate thread?

Xeakial

is API::Timer::Get().DelayExecute(&handleplayer, 5, player) asynchronous by default? or do we have to do something extra to use it on a separate thread?

Everything in Ark is synchronous

10:10 AM

Everything runs in the game thread

10:10 AM

If what you are doing does not need game stuff then you can use std thread

10:11 AM

Otherwise you need to use game thread and some synchronization

okay it is for the AShooterGameMode_HandleNewPlayer hook, I know you have to delay until the player is loaded to get the information, I was not sure if this would cause the plugin to stop completely while it was waiting if another player comes online, or if I should push it on its own thread to counteract it. (edited)

(edited)

Instead you can queue the action and after x amount of time you can do the action

1:39 AM

Which is what delay execute does

as long as there is no data loss I am fine with it delaying honestly, I mean we get a lot of traffic but I doubt enough users to cause that much of an issue coming online at once.

Does anyone know why the last bullet does not trigger the Hook_APrimalStructure_TakeDamage hook? This is very weird... Where does it go? (edited)

I just discovered, this is not the best way to check for handcuffs, and I notice this code is used in a lot of examples and etc:

c++
FString WeaponName;
character->CurrentWeaponField()->AssociatedPrimalItemField()->GetItemName(&WeaponName, false, true, nullptr);
if (WeaponName.Contains(L"Handcuffs"))
{
   // player is wearing handcuffs
}

INSTEAD you should test the blueprint path:

c++
auto weaponBP = ArkApi::GetApiUtils().GetBlueprint(player_controller->GetPlayerCharacter()->CurrentWeaponField()->AssociatedPrimalItemField());
if (WeaponName.Contains(L"Handcuffs"))
{
   // player is wearing handcuffs
}

Why? Because GetItemName() will return the weapon name in local language of the user.. So yeah, this works fine for English players.. everyone else..forgettaboutit!!

I just thought I would share

I would also use the NameField() if you know what you are looking for, as thay will never ever change. (edited)

how dangerous is a do while loop in a plugin? wanting to use it for newplayer hook and loop until all information is available.

10:03 PM

I tried the api timer, but seems like it still misses information sometimes, or just crashes.

Xeakial

how dangerous is a do while loop in a plugin? wanting to use it for newplayer hook and loop until all information is available.

if you do a while loop inside a hook you'll pause everything the server is doing, so i'm not sure how the information should become available in this case?

well the hook calls a separate function

try
    {
        uint64 steamid;
        FString uname;
        uint64 pid;
        AShooterPlayerState* state = static_cast<AShooterPlayerState*>(player->PlayerStateField());

        else
            send_info(fmt::format("UPDATE users SET lastlogin = '{}', lastmap = '{}', username = '{}'", set_time, mapname, escape(uname.ToString())));
        if (state)
        {
            if (tmembers > 0)
            {
                uint64 tribeid = tdata->TribeIDField();
                FString tribename = tdata->TribeNameField();

at least format this text with cpp syntax please

returns true to the hook if it is good, false if not.

10:07 PM

sorry most is sql.

10:08 PM

oops i think see my error. its doing it while its NOT empty lol.

regardless if you perform a while loop here you lock the server main thread

10:08 PM

the information won't become available this way because the server can't process the functions that load it

10:09 PM

void Hook_APlayerController_ServerReceivedPlayerControllerAck_Implementation(APlayerController* _this)

10:09 PM

try using this hook

10:09 PM

it's called very last in the connection chain

I see.. so back to the drawing board on that one. I had it working but it would not get usernames.

10:09 PM

okay, I will try that, thank you.

Xeakial

I see.. so back to the drawing board on that one. I had it working but it would not get usernames.

it can be empty if the character is not created

so newplayer will fire even if they are at the character creation screen?

correct

ahhh, okay. that explains the random crashes then.

10:11 PM

this one is the same? it will fire as well even without a character?

10:11 PM

so I need to set that value if its empty basically.

yes, it fires as the very last function in the connection process

okay, makes sense. I will set it to just Human or something, then next transfer or load in it will update it. thank you.

there is a hook that gets triggered on character spawn too

is that good for when they wakeup? or just when they spawn a new or after death?

10:15 PM

I will play with it, this is a great help, I though perhaps I was sending too much information and it could not keep up

void Hook_AShooterCharacter_AuthPostSpawnInit(AShooterCharacter* _this)

10:15 PM

used by arkshop

10:16 PM

as far as i know it gets called by respawning from the death screen only

10:17 PM

oh actually

10:17 PM

you might want to use the possess hook

10:17 PM

because it gets called when you access your character

10:17 PM

and you're guaranteed to have player name and other data

10:18 PM

it gets called on login and respawn though but you can track this and only invoke your functions once

10:18 PM

void Hook_AShooterCharacter_PossessedBy(AShooterCharacter* _this, AController* InController)

10:18 PM

this one

that sounds like a winner for what I need then.

10:20 PM

I also was not sure if its because I'm using a much newer connector++ than that of the arkshop and permissions. but I think it was all because of the new player. it would work great for a random amount of time.

It isn't there. I found it using IDA

IDA is very easy once you learn, but most of the functions you want to use are in the hook generator

Even the Example from the Unreal Engine documentation "FString TestHUDString = FString(TEXT("This is my test FString."));". Without FString it does succeed. I have selected an DLL Project and have the 2017 Language Standard active.

Did you do the lib include? #pragma comment(lib, "ArkApi.lib")

1

Nice, the lib include fixed the Error. I now get other Errors when I try to use the FString for AddChatCommand.

Like which ones?

For add chat command you can do: AddChatCommand("/command", &func);

7:41 PM

Also, any function from the api utils or the logger that you pass FString to, you have to use the * operator, like FuncWithArgs(*fstr); (which isn't the case for AddChatCommand, but the errors mention it) (edited)

Trying this I get the same Error as before.

Is the correct fix by any chance *(*message) in the call to sendservermessage? (edited)

8:09 PM

The error isn't in the add chat command, so yeah the issue is you need to pass *message

8:10 PM

Just one * operator is enough, the * operator returns the character data which the fmt::format needs

If I use one * I get an error, maybe because the Pointer has the same name?

8:14 PM

On the other Hand, if its already a Pointer why doesn't it work in the first place xD I'm obviously a total noob but I'm happy it compiled without errors for the first Time

Ah yeah my bad, I didn't see it was a pointer

8:21 PM

Then yeah, double **

Is there a limit at some point where to much database integration will cause issues that any one has noticed?

Xeakial

Is there a limit at some point where to much database integration will cause issues that any one has noticed?

Not really. I've come accross issues when I started doing multithreaded sql applications, you have to be careful of data management, using mutexes and such stuff. But doing too many sql queries will just depend on how many entries on db, and could potentially lag the server if the query takes too much.

10:49 PM

I'm not sure if I answered your question, though.

okay, I know for sure I was having buffer overflow issues with players logging in and collecting information, but I solved that by delaying the queries for a bit to give it time to load the base.

If you do sql operations on player login, and they take relatively too much time, they could overflow once its done, it's technically possible yes

Yeah it certainly was for me, it was a constant issue, but I ended up splitting up the load from when they logged in, giving it 60 seconds before it started sending info to the database, and send the rest when they log out.

Yah, when players log in the server sends pretty much big data to clients, if server stalls before sending them that info, server ends up sending the login data + other data that happened during the stall. Or at least that's what I can think of (edited)

yeah, had to figure that out the hard way lol. but the new project I am working on is based off of the Config Manager, I want to use a database to store the config options so I can also access them via webpage, and discord bot, but I am worried that it could be too much and am debating going to a ini style file instead.

10:56 PM

but that brings a whole new issue of making sure the folder is shared for all the maps I want to effect, and having accessible from the bot and web server, so it would have to be a synced folder basically. decisions decisions lol.

I'm probably the worst beginner ever :X Now I get Error Code 126 from the ArkApi Plugin Manager when starting the Server with my simple plugin from above. I have installed the c++ redists and the Permission Plugin is loading without error.

I'm probably the worst beginner ever :X Now I get Error Code 126 from the ArkApi Plugin Manager when starting the Server with my simple plugin from above. I have installed the c++ redists and the Permission Plugin is loading without error.

What is your plugin's name?

I tried so many times with different Names. "FirstPlugin" for Example. Folder and Dll with the same Name.

If your plugin's name first letter is above "P" in alphabetical order, it will fail to load unless you delay load it. To Delay load it go to project settings -> Linker -> input -> delay load dll, write there Permissions.dll and recompile

Still doesn't work. I also named one Plugin "xxxx" and same result. Whats weird is that I have one super naked Plugin without include Ark.h and the pragma ArkApi.lib and that one is loading too.

The api will attempt to load the dll, if it hasn't got any api code it just won't run any api code

12:04 AM

126 is missing dependency, so something is up

My Plugin is just this small. Cant wrap my head around why that would not load while the permission plugin is. Could the default files that Visual Studio creates affect that?

Shouldn't need any permissions include then, you should remove the delay load as well

Re install vc++ redistributables

Dodo Enthusiast

My Plugin is just this small. Cant wrap my head around why that would not load while the permission plugin is. Could the default files that Visual Studio creates affect that?

I don't see the Log::Get().Init("PluginName"); in your load.. You have to have this line in my experience.

7:49 AM

should look like this

#include <Windows.h>
#include <API/ARK/Ark.h>
#include <Logger/Logger.h>
#pragma comment(lib, "ArkApi.lib")
void Load()
{
    Log::Get().Init("YourPluginName");
    <-- add commands here
}
void Unload()
{

}
BOOL APIENTRY DllMain(HMODULE hModule, DWORD ul_reason_for_call, LPVOID lpReserved)
{
    switch (ul_reason_for_call)
    {
    case DLL_PROCESS_ATTACH:
        Load();
        break;
    case DLL_PROCESS_DETACH:
        Unload();
        break;
    }
    return TRUE;
}

And the pluginInfo.json file in the folder "YourPluginName" should look like:

{
  "FullName":"YourPluginName",
  "Description":"Description of your plugin here",
  "Version":1.0,
  "MinApiVersion":3.2
}

(edited)

Thanks again everyone. I found my Issue. All Projects I did with the old file problem were set to release, but at some point after I fixed that issue I forgot to set it to release. Sometimes its better to sleep a night over it

Log Init should only be necessary if you are using the logger

1:22 PM

If you don't init the logger and try to use it, it will crash

Sorry for newb question - is there a way to disable voice chat entirely server side? I would like to start a server, which our community has strict moderation guidelines that we would love to enforce. I am thinking that we turn on global voice, however, we could toggle this been on when staff are online, and then toggle off when we dont have moderation team joined.

4:48 PM

I have had a good read on the forums and nothing looks like they have tackeled this problem.

I'm not really sure you can do that, might be since voice chat has to be sent back and forth to/from server

I'd be happy to disable voice chat entirely and just rely on text (and logging of the text chats).

I feel kinda bad that I'm the only one asking so much in here. If its too much please tell me. I have one more Issue. I'm iterating over the GetWorld()->PersistentLevelField()->GetActorsField() and try to destroy some structures. The server just crashed everytime, even without error. I tried UVictoryCore::KillTargetCharacterOrStructure APrimalStructure->destroy() APrimalStructure->SetHealth(0). Does the destruction of one item in the GetActorsField basically kill the loop?

Which crash are you getting? (call stack)

I'll try it again but I'm pretty sure I didnt get a Error Window it just closed the server-terminal

Are you calling your function after game init?

9:50 PM

also could type another method like...

c++
TArray<AActor*> FoundActors;
UGameplayStatics::GetAllActorsOfClass(reinterpret_cast<UObject*>(ArkApi::GetApiUtils().GetWorld()), APrimalStructure::GetPrivateStaticClass(), &FoundActors);

for (const auto& actor : FoundActors)
{
    auto structure = static_cast<APrimalStructure*>(actor);
    if (structure && structure->IsA(APrimalStructureItemContainer::GetPrivateStaticClass()))
    {        
        // do something with structure

        // structure->Destroy();
    }
}

(edited)

For now I have a chatcommand I type in myself while on the server.

9:52 PM

Could my Problem be that i dont have a FoundActors but im doing the destroy inside the initial Loop over PersistentLevelField()->GetActorsField()?

show us your code

9:53 PM

thats the easiest way

I basically comes down to this

If i dont do the kill/destroy but just Log the structures that satisfy the conditions it works

Try using Destroy() or Suicide()

I just tried a completely new savegame and it suddenly worked destroy and suicide both. Thanks again everyone.

And the UVictoryCore function still kills the Server

Hi, I also started just some days ago. What helped my was doing the guide https://discord.com/channels/513432877904691202/513502790228639775/514540051615449089 from #【🔶】ᴘʟᴜɢɪɴ-ᴛᴜᴛꜱ but with the files from https://github.com/Michidu/ARK-Server-API.

So since i cant find a ORP mod that works i want to try doing plugins. I just got Visualstudio 2022 and i dont know what to pick to install

did you look at the #【🔶】ᴘʟᴜɢɪɴ-ᴛᴜᴛꜱ ? https://discord.com/channels/513432877904691202/513502790228639775/514540051615449089

Trying to use either of these two hooks to ignore when a player is too close to another player to build for an event, is this even possible through hooks? Or should I try making a mod to do this?

DECLARE_HOOK(APrimalStructure_IsAllowedToBuild, int, APrimalStructure*, APlayerController*, FVector, FRotator, FPlacementData*, bool, FRotator, bool);
DECLARE_HOOK(APrimalStructure_CheckNotEncroaching, bool, APrimalStructure*, FVector, FRotator, AActor*, APrimalStructure*, APrimalStructure*, bool);

(edited)

it's possible, i think you'll need APrimalStructure_IsAllowedToBuild and in that hook you just scan the area of the structure position and look for other tribe structures using UVictoryCore::ServerOctreeOverlapActors

I figured OctreeOverlap would come into play as it was what I seen on some mod examples. Thank you I will try that.

no problem, there are plenty of examples on here as well

Is it normal that it seems I have to start the server twice to get a Hook working without crash or am I doing something wrong? Or is there a Problem with using the info Log from inside a Hook? (edited)

verify server files and reinstall the ark api files.

Lethal

verify server files and reinstall the ark api files.

Thanks its not crashing anymore although the api files seemed the same and there was no update in the Server Manager. I'm still kinda confused but I will take it

Does the hook creator not work anymore?

12:57 AM

I am just having trouble getting started

what version are you using?

1:31 AM

Release 1.8 Fix · Pelayori/Tools

Thank you this worked, if i am trying to make a plugin to stop pulling to turrets can this tool help with that?

well sure, it's a great tool for looking up all the different hooks and getting the code easily

I just am looking for a basis to venture off from and wasn't sure if this would offer any ideas

i would spend some time in the free examples that are available

void ShowM(int delay)
    {
        if (delay > 0)
        {
            DEBUG_INFO("Timer {} ", delay);

            delay--
            API::Timer::Get().DelayExecute(&ShowM, 1, delay);


            return;
        }
    }

I am trying to DelayExecute inside DelayExecute like the code above, This is crashing on the seconds execution. Is there a reason i cant call DelayExecute inside DelayExecute? I am trying to show a count down for the user something like 5, 4, 3, 2, 1.

What’s the crash stack

does that even compile?

don't you need a semicolon after delay-- ?

jraServerAPI

does that even compile?

I removed my comments and removed a bit too much

I've used nested delay execs without issues

Somehow it is working now. I guess I just needed to sleep

I am trying to improve um teleport plugin, right now a timer is displayed and after that I just set the player position. I would like to improve two things: The timer uses SendNotification every second, it looks like the message is blinking. Is there a way to display a fixed text on screen that updates just one part of the text? Another thing that I think would be cool is to show a teleport bubble similar to when the player start boss or the genesis teleport feature. Is such thing possible with just plugins?

For the first you should use AShooterPlayerController::ClientServerNotificationSingle. The last parameter is a message id, if you make it the same for your every second notifications, the text will be updated rather than resent (might as well add 1.5 seconds of display time so it doesn't blink either way) About the latter I'm not sure.

Example:

player->ClientServerNotificationSingle(
                &msg,

anyone else notice since Fjordur this hook no longer works? DECLARE_HOOK(ReportCrash, int, void*); Not sure if its just stuff I added to the plugin or if it just changed or something. (edited)

It should work afaik, do you have any issue with it?

It was working great until Fjordur Launched, I have not updated the plugin I use it in since before the launch, but it has failed to catch a single crash since the new map launched, before that it was about 90% successful.

In my experience it only works with crashes that output a crashlog, if they don't have a crash log (silent crash), it will fail to do anything

yeah, that was about the right situation it was working before. I was just wondering if any one else was experiencing the same issue. All I know is it has not caught a single crash since the update. Which was starting to make me think they changed the way it hooked or something.

‍♂️

I haven't had any reports of that feature not working, but it's fairly easy to test. I will get back to you if I get the chance to test it today

Okay, I will also test it on my test server, just figured I would ask before I did that as im sure quite a few people use it, its an amazing hook that was saving me a lot of trouble.

I have tried several different ways to crash the server and it for sure is not picking any of them up...

in my local files? i watched a video on the website? i'll be honest, i am completely clueslees on how to do this

local files where

8:38 PM

in your steam folder?

games-steamapps-common-ark-shootergame-binaries-win64

yeah that won't work lol

8:39 PM

you need a dedicated server

i have one rented via gportal

8:39 PM

i want to put the mod on there and therefore the plug ins but i just dont really know how

then install them on your server and not on your client

how do i do that?

8:40 PM

i can do the mod bit. i just dont get how to do the plug ins

i don't know how GPortal handles plugin installation you should ask their support

8:44 PM

maybe you can upload the files manually via ftp

would i use ftp to access the necessary files for the server to install the plugins?

8:45 PM

oh nevermind lol

I submitted a pull request with that change a couple months ago at @Pelayori's request. Never got reviewed. You can hook the function normally, just can't call it safely with the current definition in the header. There's also a SpawnFromDinoData (no Ex) that could be added.

Hi all. Very new to Ark Server API and super curious: How do you get the game to load your DLL? Does itjust hotload every dll it finds in Binaries\Win64?

version.dll is a windows library

8:10 PM

The game links against it

8:10 PM

The internal linker in windows searches the directory of an executable before falling back to system path

8:11 PM

By placing this library in the same directory, windows loads this instead of the dll from system32

substitute

version.dll is a windows library

I would like to tap into the tek forcefield and remove the need to use elements and force turn on/off and range, is that something that is possible with plugins? Can I have some general directions on how to do it?

Force turn on/off is just the APrimalStructureItemContainer::SetContainerActive function For removing the need of elements you could do something like add 1 element when the structure is placed, force turn on and set the fuel burn rate of the structure to very high values (practically making it infinite lasting) For the range, there is a formula. I decoded it from the devkit and it can be found in the safe zones plugin source code, on the bubble spawn function

The burn rate, can you give general directions on how to do it?

I think it's a hook

will try to find, ty!

APrimalStructureItemContainer::BPGetFuelConsumptionMultiplier

10:02 PM

that is, hook that function, and if _this is a forcefield return a very low value (since that function takes a multiplier) Example: 0.00000000001 or something.

10:03 PM

Also might have to set bUseBPGetFuelConsumptionMultiplier to true on the forcefields

will try, thank you

Pelayori

that is, hook that function, and if _this is a forcefield return a very low value (since that function takes a multiplier) Example: 0.00000000001 or something.

Why not 0

Oh yeah lol

x - a*b where b is 0 is just x - a0 = x

10:15 PM

Yeah but you never know if wildcard decided to do a division or whatever they sometimes do

You’ll also want to block people from removing the element too

But yeah, 0 is probs the wanted value

Pelayori

Yeah but you never know if wildcard decided to do a division or whatever they sometimes do

x/0.0000001 >>>> big value

10:16 PM

So that could be dangerous too

If you add and turn on on the same func it shouldn't give time to remove it from inv

substitute

x/0.0000001 >>>> big value

I know basic math, even though it doesn't seem like it

Pelayori

10:18 PM

This works, just freaks out intellisense. In the real version printName would be the callback itself (static function on the type) and the reset call would be internal and would use the pdb and the string in the type definition to find the address

10:18 PM

For doing plugins that don’t need to install their own hooks

10:18 PM

And can have pre and post call handling

i am trying to figure out how many free slots the player has and right now I am doing: pc->GetPlayerInventoryComponent()->GetCurrentNumInventoryItems() - 299

7:44 PM

but GetCurrentNumInventoryItems also counts engrans the player has

7:46 PM

is there any other way to get the free slots of the player inventory besides looping each item and ignore bIsEngram ?

Let me check what that function does in ida, because if it's looping you would do the same

7:47 PM

__int64 __fastcall UPrimalInventoryComponent::GetCurrentNumInventoryItems(UPrimalInventoryComponent *this)
{
  return (unsigned int)(this->InventoryItems.ArrayNum - this->DefaultInventoryItems.ArrayNum);
}

(edited)

7:47 PM

That might not be exact for players

7:48 PM

As players' inventory has only note and pick as default inv items

to get the players items I usually do items = inventory->InventoryItemsField(); and do a loop ignoring item->bIsEngram()() and item->bIsInitialItem()()

7:51 PM

I find very odd that engrams are returned on InventoryItemsField

They are items itselves

7:52 PM

They are just treated different

7:53 PM

Try this:

int GetInvCount(AShooterPlayerController* pc)
{
  AShooterPlayerState* sps = pc->GetShooterPlayerState();
  return pc->GetPlayerInventoryComponent()->GetCurrentNumInventoryItems() + sps->EngramItemBlueprintsField().Num();
}

7:54 PM

About the actual slot count, I think it might be located in UPrimalInventoryComponent::AbsoluteMaxInventoryItems (only on players, though)

I see, that looks like a nice solution, will try!

I'm not so sure that EngramItemBlueprintsField is the learned engrams, but after looking some ida code seems reasonable that is the field

wait, can you go pass the limit ?

Inventory's max slots are in MaxInventoryItemsField, however there are a few more extra slots that are defined in AbsoluteMaxInventoryItems. These extra slots that the player can't use are for things like spoling meat, etc. So the inventory can store them but players can't add more items until the count is below the normal max inv items

man, I played this game for 7 years and did not knew that

You can see that if you leave a full inventory say a smithy full of raw meat, and let them spoil one time, you will have overcap of slots, something like 101/100 and such

the containers I know you can go pass the limit, but the players inventory I never took notice of it

8:00 PM

and from what I can remember you could put 430 slots

Player inventory is different, I believe it only uses the absolute count, ignoring the normal max

now is it only 300

Pelayori

About the actual slot count, I think it might be located in UPrimalInventoryComponent::AbsoluteMaxInventoryItems (only on players, though)

this does not work, somehow I end with -462, will go with the loop. Ty!

Nvm I just found out that the plugin Max-Imprint shared in #Plugins channel is using Permissions plugin so I will use that as example (https://github.com/barnwellrd/Max-Imprint/blob/master/MaxImprint/MaxImprint.h). (edited)

Any idea why the call to Permissions::GetGroupMembers("Admins"); freeze my server? I call it from AFC_LoadPermissionsArrays() function that is called every 30 seconds like seen in Max-Imprint plugin:

API::Timer::Get().RecurringExecute(&AFC_LoadPermissionsArrays, 30, -1, true); // Continuously updates the admins and allowed players arrays.

Why not look at something like ArkShop that is updated and was built using the current permissions.

7:18 PM

Copying old code you have no idea why it was done that way is not a good approach

Ok I will have a look there as well, thank you

Yep, definitely works way better without the cached array initialisation and recurring refresh. Using Permissions::IsPlayerInGroup( instead of Permissions::GetGroupMembers(. Thanks again ^^

What have you done to include the mysql?

Pelayori

What have you done to include the mysql?

1. downloaded arkshop source from michidu 2. installed the mysqlc++ connector 3. arkshop includes as additional includes 4. arkshop Lib as additonal library (the lib folder where the mysqlclient.lib is inside) 5. as a first step I only included the mysql++11.h and the mysqlclient.lib and try to compile it and the errors already start (edited)

Are you using the C++17 standard?

yes

12:47 PM

I added the things above to a small plugin that already worked correctly ingame.

Could we see your includes and the libs?

12:55 PM

Did you link both arkshop and mysqlclient libs in your code?

only mysqlclient

Did you include Windows or winsock in any of your source files?

No its only a super small one file plugin so far.

It's hard to debug at this point without more info about the plugin solution.

I am getting Error code: 126 after adding ArkShop as a dependency to my plugin, I understand that this is a missing dependency, but how do you make a dependency optional?

Has you added: if (ArkApi::Tools::IsPluginLoaded("ArkShop")) {}

Yes, and also have the #pragma comment(lib, "ArkApi.lib") on my cpp file. When i have the ArkShop plugin loaded is working as expected, but i would like to make the arkshop plugin optional

Uaca

Yes, and also have the #pragma comment(lib, "ArkApi.lib") on my cpp file. When i have the ArkShop plugin loaded is working as expected, but i would like to make the arkshop plugin optional

then you have to invoke ArkShop functions using GetProcAddress

2:34 PM

and run IsPluginLoaded before invoking such functions

2:34 PM

then you can remove ArkShop as a dependency

2:37 PM

https://docs.microsoft.com/en-us/windows/win32/api/libloaderapi/nf-libloaderapi-getprocaddress

GetProcAddress function (libloaderapi.h) - Win32 apps

Retrieves the address of an exported function or variable from the specified dynamic-link library (DLL).

2:38 PM

you pass a module handle to it, which in this case will be a handle to ArkShop.dll (if loaded)

2:38 PM

and you pass the function name you want to call as the second param

2:38 PM

it will return the function address

2:38 PM

then you can call the function

2:38 PM

this way you don't have to hard link with ArkShop

I see, that might be a bit hard to do it. Will try. Thanks!

Uaca

i cant get it to work

That might be due to C++ name mangling, as the shop exported functions do not have extern "C" in their def/decl. I'd work out why it isn't working. Is your plugin name loading before arkshop is, or do you have any other dependency?

The mangled function name is: ?SpendPoints@Points@ArkShop@@YA_NH_K@Z

MyPlugin::UseArkShop = true;
if (!ArkApi::Tools::IsPluginLoaded("ArkShop")) 
{
    MyPlugin::UseArkShop = false;
}

And it works fine for me

that is odd, when I try to load my plugin with arkshop dependency it gives me error 106

Pelayori

That might be due to C++ name mangling, as the shop exported functions do not have extern "C" in their def/decl. I'd work out why it isn't working. Is your plugin name loading before arkshop is, or do you have any other dependency?

ArkShop is loading before my plugin and there is a dependency to Permissions

Do you have both plugins in delay load in your plugin? (edited)

Pelayori

yes

The mangled function name is: ?SpendPoints@Points@ArkShop@@YA_NH_K@Z

Try using this name then, instead of just SpendPoints

this one the addr is not null

6:10 PM

will try to call and see if it works

6:10 PM

how do I get the real name of the function?

There's a program called Dependency Walker, it's old but easy to use

I see, will try to find it

6:12 PM

but that looks odd, I mean, if the name is ?SpendPoints@Points@ArkShop@@YA_NH_K@Z, can it change between versions?

It will only change if that function is ever changed again (when a new .lib needs to be used) (edited)

6:18 PM

Those are all the names of arkshop functions, notice how Plugin_Unload isn't mangled since it uses the extern "C" construction

yeah, it makes sense

6:19 PM

it worked, I was able to call the SpendPoints

many thanks!

I disagree

11:39 PM

C++ name mangling shouldn't destroy exported functions

It doesn't destroy them, but if you need to find them you have to use the full name

anything that is mangled....you shouldn't use the mangled name bign_kirby_pengu_lol

My knowledge on those fields is limited peepoChat

if it is exported, then you need to link against the library properly

11:40 PM

set it as a delay loaded DLL

I agree, but I'm not even sure why would give error 126 for him

ArkApi::Tools::IsPluginLoaded("ArkShop") + delay loading is all you need

11:42 PM

if they are getting error 126 then they are probably doing something in DLLMain that isn't entirely supported

If you can read above and check if we missed something would be great

if I had to guess, they didn't set it to delay loaded dll properly?

@Uaca could you verify this?

as in, if ArkShop is not present the plugin won't use it's features

like this?

It works only if ArkShop is loaded, when I remove the ArkShop plugin it starts with error 106

1:36 AM

The DLL main is a copy from others plugins:

BOOL APIENTRY DllMain(HMODULE /*hModule*/, DWORD ul_reason_for_call, LPVOID /*lpReserved*/)
{
    switch (ul_reason_for_call)
    {
    case DLL_PROCESS_ATTACH:

}

If DLLMain has any exception your DLL is unloaded

I usually do nothing in DLLMain

https://docs.microsoft.com/en-us/windows/win32/dlls/dllmain

DllMain entry point (Process.h) - Win32 apps

An optional entry point into a dynamic-link library (DLL). When the system starts or terminates a process or thread, it calls the entry-point function for each loaded DLL using the first thread of the process.

See the big warning section

3:53 AM

Creating a thread isn’t inherently safe either

A better solution in the future would to have plugins export a load and unload function

So that the api can call that after loading the library

Might be worth getting its ai controller and checking if target Field is nullptr

hello everybody I want to create a plugin ,Some dino were not allowed to be cloned, I tried a lot of hook, such as:GetDinoData BPOverrideAllowStructureAccess ,But none of them worked, i found StartCloneDino, But I don't know how to hook him, I hope to get yours help, Thanks

okay, I get where your going, if its not null they must be targeted on something. I will give that a shot, thank you.

Well getting the ai controller did not work, but just using your suggestion with APrimalDinoCharacter* and checking if (Dino->TargetField() != nullptr) does work. I did not even think to check and see if target is nothing, so thank you again for the help

Any luck on getting a hook for before a genesis mission starts so I can stop it from starting? or would I have to use a mod for this on the client side?

If I pull the information from the server it says it changes, but in game eggs do not hatch any faster no matter what I set it to. (edited)

Any server setting on the game mode is present on the shooter game state which is the responsible of actually applying the settings to the game, and replicate them to players

is there a way to get steamid or uid from UPrimalInventoryComponent? ArkApi::GetApiUtils().GetPlayerID(inventoryComponent->GetOwner()); ArkApi::IApiUtils::GetSteamIdFromController(inventoryComponent->GetOwner()); both return 0 when the player is offline (edited)

you could try this: inventoryComponent->GetOwner()->TargetingTeamField() then try loop characters in the world and get the player id that way maybe

nah, might be a very bad idea lol

Foppa

It's an issue we've discussed at length in the past, but a solution hasn't been forthcoming as yet.

Well first to get a steamid or playerid there is demands. But first you want to look at the inventory component if it's owned by a AShooterPlayerController

12:13 PM

i see why this is a tricky nut to crack tbh (edited)

Accessing certain information when players are offiline is a very common issue people run up against. My suggestion in the past was that the API itself cache that information and make it available even when they are offline, as it does for some other things, but that seemed to be a contentious idea. lol

It's better to make a plugin handle that part tbh

12:15 PM

and make an API for plugin to request against

12:15 PM

I might do that with my player activity and make the plugin for free

12:16 PM

as that plugin is already storing like everything by a player

What I said previously was that any kind of functionality that involves basic aspects of UE and that is done over and over again by many plugins should be considered for inclusion in the API. I don't understand why it wouldn't be. (edited)

Sorry to interrupt, As soon as the api becomes more complex, it will start to become endlessly complex. And caching is a feature that some plugins don't need. This makes the api a bit heavy. I think that the api should only provide the api, but not extend the function.

My goal was to prevent items from transferring and equipping, it would be better to catch when it is happing, but looks like also fire for each player when the map starts and I can use that. But makes no sense to be that hard to find out to who the body belongs, the game has to do that when the player connects.

If so, there is a solution. Hook_AShooterGameMode_HandleNewPlayer Use this hook. Called when the user has access to the character (online, character creation, etc.).

Hey everyone, I am still having a issue with changing this setting bellow. I have tried several different ways and actively use GetShooterGameMode to change about 10-12 game settings on the fly, but for some reason EggHatchSpeed just will not change, is anyone else having this issue? Every other setting works fine except egg hatch speed.

const auto SGame_Mode = ArkApi::GetApiUtils().GetShooterGameMode();
const auto SGame_State = ArkApi::GetApiUtils().GetGameState();
AShooterGameState* Sh_Game_State = static_cast<AShooterGameState*>(ArkApi::GetApiUtils().GetShooterGameMode()->GameStateField());

SGame_Mode->EggHatchSpeedMultiplierField() = fval;

SGame_State->EggHatchSpeedMultiplierField() = fval;

Sh_Game_State->EggHatchSpeedMultiplierField() = fval;

I would assume your most likely cause is due to replication, you will have to force the client to accept and notice this change, there is a nice open source on github called Improved Commands that can probably help. Specifically the MyDinoStats one or the respec ones. There is a section that uses "reinterpret_cast<UActorComponent *">"then use that to RescaleAllStats which is how it is usually done in the DevKit. (edited)

I am trying to set item->BlueprintAllowMaxCraftingsField to limit the number of crafts, it has no effect. Does anyone know if it possible to limit the craft this way? I think I saw a plugin that limit the craft of bps, but I cant remember the name.

Lethal’s Items+ plug-in has that ability I believe!

I found it, but is limits for the server, I wanted for only on BP

thanks . emmm I have no idea how to get FTribeData with tribeID(offline? tribesDataField() All found are online)

Only way you can get that information while the tribe is offline is with GetOrLoadTribeData but do a little searching as you will have to pre-allocate memory for it and free it when your done.

here's some code i found:

c++
AShooterGameMode* gameMode = ArkApi::GetApiUtils().GetShooterGameMode();

static int tribeDataStructSize = GetStructSize<FTribeData>();
FTribeData* tribeData = static_cast<FTribeData*>(FMemory::Malloc(tribeDataStructSize));
RtlSecureZeroMemory(tribeData, tribeDataStructSize);
gameMode->GetOrLoadTribeData(player_controller->TargetingTeamField(), tribeData);

// do something with tribe data
const auto iDinoCount = tribeData->NumTribeDinosField();

FMemory::Free(tribeData);

thank you

I've hooked it before to prevent Cryopods from releasing in certain areas. It's a script UFunction that gets called through UObject::CallFunction().

    {
        // do the thing

hello a,I want to create a custom tribe ID.

5:49 PM

I tried Hook_ AShooterGameMode_GenerateTribeId(), But I don't know which usercontroller

5:49 PM

Is there any other way?

When taming a dino, you can enable that marker on the HUD to display a location of where the dino is. Does anyone have an example of how to do that, or know the function that can do something like that?

Donsora

hello a,I want to create a custom tribe ID.

That will not generate a tribe id, it will just be called when the server generates a tribe id.

9:44 PM

You would have use the hook to catch before the information is returned and assign an id, but I don't even know if it is possible tbh.

It is, if you modify the return on that hook the next tribe Id will be the one you return.

9:55 PM

You can combine create new tribe hook and generate id hook to create a tribe with your own tribe id

That is good to know, and gives me an idea.

9:57 PM

could basically sync all tribe ID's across maps like that.

There's also another method, like creating the tribe manually first then adding players. There's a function in the game mode to force create a tribe with preset tribe id

I was just looking at that oneDECLARE_HOOK(AShooterGameMode_ForceCreateTribe, int, AShooterGameMode*, FString*, int);

Should probably have extra clarity on not starting the game with the dll in the directory

if it were to be loaded into the game while BattlEye was running, you would like receive a BattlEye ban

Pelayori

There's also another method, like creating the tribe manually first then adding players. There's a function in the game mode to force create a tribe with preset tribe id

what's the another method?ForceCreateTribe?I'm not sure the “teamOverride<int>” what's mean

6:57 PM

I call the method but nothing happened

Donsora

what's the another method?ForceCreateTribe?I'm not sure the “teamOverride<int>” what's mean

Team override means create a new tribe with X tribe id

then load the tribe by this id?

Yeah, that'd be

and join the tribe

The server creates it, but just empty and no data other than the tribe id

thank you , I'm going to try

is there a hook for map save?

AShooterGameMode_SaveWorld

hello ! is there a hook when the character created?

 Found in the Hook Creator

Hello, I was wondering if someone can explain to me how to set up Visual Studio 2022 or Visual Studio code to build plugins. briefly about me: i just started this week with C++ and i have downloaded other plugins as sample code but i can't manage to compile them cleanly all the tutorials i have found so far are for older versions of visual studio

ok it was a classic "60cm in front of the monitor" error if I specify a lib in the code I should also make sure that the system finds it under the specified path.

Hello, is there a way to remove a world buff on gen2 with the end mission hook?

Hi, I'm looking for info on how to access Dino stats/buffs and how that data is stored. Where can I find it?

search this discord for the word: buff

1

It is possible to gell all tribes and its members steamid? or this info is available only when players are online?

you can do that by tracking players that join your map and you keep the data stored in a db

yeah, I was hooping that it would not be the case. The player can join a tribe, a tribe can merge, the player cant leave out be kicked out of the tribe. It would be much better to just get this info from the server

Uaca

you can use GetOLoadTribeData to load a tribe's data by inputting the tribe id as the argument

3:36 PM

it returns a struct with tribe data such as all members and stuff

3:37 PM

this is how i do it

3:38 PM

i load all tribe data on plugin load and then make my own cache for it so i don't have to call GetOrLoadTribeData every time

3:38 PM

since the function leaks memory

that is nice. ty!

How do I call this. it`s in Primate->Commands.h

4:39 PM

help me!

You don't need to call that

6:20 PM

It's handled automatically by the api

oh thank u

6:22 PM

I find the ChatMessageCallback

If I have a pointer to a structure in the world, like a foundation, what is the easiest way to get a UPrimalItem reference of that structure?

after much investigation, I'm conceding that there probably isn't a way to do this in the API, and I'm resorting to making a hardcoded lookup list instead

‍♂️

APrimalStructure* _this;
_this->ConsumesPrimalItemField();

Perhaps?

oh man.. i did not see that!

9:30 PM

i'll give it a try..ty!

I been looking at doing the tutorials for plugins, however the links just get redirected to the download page, does anyone have an updated link for Hooks?

Trying to work out how to and where to put them in Code etc. "trying to create a hook to beaver dams eventually, guess I need container in general and only do stuff if == to beaver dam."

What, specifically, are you wanting to do with the beaver dams?

When you open them anything you don't take will be dropped and dam destroyed.

I managed to find the hook tool via google as only the first Tutorial link works for me.

Hi, I'm trying to deconstruct a Property from the Extinction Drops. For now I got most of the information from the Devkit. The Property gets found but I always run into the size error. First of all can I even get and set such a property? If yes how would you go about to figure out where the Problem is? I also don't really know what is meant with "Actor Class" and "Primal Dino Class" in this context.

It depends, if the property is only exposed in BP then you will need to use the reflection system in UE4 to get or set it

7:19 PM

There are helpers in the API to do this.

7:20 PM

Actually the size error is a guardrail that the helper uses

7:21 PM

The type you are reading as is not the same size in bytes as the type UE4 says it is

7:21 PM

Ex: reading 8 byte property into 4 byte storage

7:22 PM

I should probably make the error more clear and show the size difference with something like

Size error x bytes being read into y bytes, wrong type passed

7:23 PM

In your case though I think you are using it wrong … I’m on mobile so I can’t read the code very well

7:24 PM

If you are reading a property of a property you will need to find the UProp of the nested property and .Get that

7:25 PM

I’ll probably rewrite the helper to be easier to use in the future at some point

7:28 PM

The way Get works though is on UProp you call Get with the arg being the instance of a class that contains the UProp

7:28 PM

And then it reads the size of the type T that you passed in as the type arg bytes as a T

7:29 PM

Basically at the offset of UProp in Class it reads sizeof(T) bytes as an instance of T

I am pretty sure this should be a pointer to AActor though, AActor* ActorTemplate; //Dev Kit says "Actor Class"?

Pelayori

I am pretty sure this should be a pointer to AActor though, AActor* ActorTemplate; //Dev Kit says "Actor Class"?

I think adding a get and set to UObject that takes the name and uses reflection is how I’ll improve the user experience for this

7:31 PM

The original on UProp can be left as the “fast” version since it’s just using pointer arithmetic

I just tested it just for fun with AActor* and UClass* and there is no error anymore. But I cant believe it does really work xD. Need to test it further.

I see a bit of room for optimization, but it ain't the worst thing tbh, I use it a lot without issues

Dodo Enthusiast

I just tested it just for fun with AActor* and UClass* and there is no error anymore. But I cant believe it does really work xD. Need to test it further.

The error you were getting wasn’t an issue with Ark per say

Because the AActor of the api is not the correct size, plus it was expecting a pointer there to get the size correct

The error was from the API being defensive about mis-sized storage

7:32 PM

Since your original one was the wrong size in bytes

7:33 PM

Anything that has non-pointer classes and structs is going to most likely throw the wrong size error since the types in the API aren’t 1:1 to the game (edited)

I assume there are still problems but need to test it first.

Pelayori

Because the AActor of the api is not the correct size, plus it was expecting a pointer there to get the size correct

I could fix that though by having an overload that accepts T where T has a getSize that compute the size using reflection

7:34 PM

However that would be unsafe since you would also need x bytes of data storage

7:34 PM

Perhaps we could also internally allocate a buffer of memory as storage

Could use a helper class to save the data you need to refer to later

7:35 PM

A bit more of mem tho

Thats all way beyond my understanding

Dodo Enthusiast

Thats all way beyond my understanding

You’ll get there eventually

7:35 PM

If you search my very first messages here you'll see where I came from, from zero

I just sure do love template meta programming

7:38 PM

You’d probably never touch C++ again if you saw the Eldrich horrors I’ve come up with.

Thanks for the answers. I will do some testing. I used a Template for the first time like 2 days ago :X

I templated function hooking to the point where I can generically hook a function while providing an interface for pre and post callbacks

7:40 PM

It was total wizardry

7:40 PM

I’m still prototyping v3 of it before I push it to GitHub

7:41 PM

I’ll eventually release this

7:42 PM

Eventually

7:42 PM

@Pelayori imagine Tebex integration with THAT

7:42 PM

Now that’d be a in game shop

substitute

I’ll eventually release this

Are you using rcon commands for that?

Substitute using rcon commands, pfft

7:51 PM

Think it's some sockets library for http calls or similar

Dodo Enthusiast

Are you using rcon commands for that?

No rcon

9:17 PM

It’s a web server running inside of the game

9:18 PM

The http file is making api calls to the web server

Ok thats next level^^ The structs from above seem to work so far with the small changes to pointers. I can even set it again with changed dinos and levels. Thanks again for taking the time to answer.

What is the best way to use the Hooker Creator? Looking to get the state of a beaver dam, but I guessing at this stage it is going to be a mod job.

What is the best way to use the Hooker Creator? Looking to get the state of a beaver dam, but I guessing at this stage it is going to be a mod job.

Depends, what’s your specific want with wanting to drop the items

9:51 PM

If it’s drop all unclaimed items regardless of item type

9:52 PM

Then you need to hook when an inventory is opened, check if the type of the inventory container is a beaver dam, and track that a specific dam was opened

9:52 PM

I don’t think there’s a method for when something is closed

9:52 PM

So you’ll have to make your own detection for that

substitute

I don’t think there’s a method for when something is closed

If there is, then hook this instead and check if it is a dam and drop everything

SarahWild

When you open them anything you don't take will be dropped and dam destroyed.

If it helps, I have code for a simple plugin that drops everything from a beaver dam when a player closes the inventory with only wood remaining. https://github.com/MolluskARK/MolluskARK-Plugins/blob/master/Projects/TidyDams/TidyDams.cpp

your hook on Hook_UPrimalInventoryComponent_ServerCloseRemoteInventory is why I want to finish my autohooking prototype

9:48 PM

if another plugin hooks it and runs before yours (and doesn't call the original) then your plugin would break

9:48 PM

it's such an annoying problem lol

substitute

if another plugin hooks it and runs before yours (and doesn't call the original) then your plugin would break

When I wrote my own plugin loader / hook manager, I toyed around a little with allowing hooks to be registered as pre-hooks or post-hooks. And the original function would always be executed in the middle. I ended up using the same style of hooking as ArkApi though, where each hook that's registered gets an "original" pointer. I've had one or two instances in the past where I just wanted to replace the original function without it ever getting called. Plugins failing to call "original" was always less of an issue for me because even when I use ArkApi I tend to only use plugins I have source code for.

You can do it with an event handler

after this , only Hook_AShooterGameMode_UpdateTribeData is called but Hook_AShooterPlayerState_UpdateTribeData is not called

2:08 PM

if I call player_state_updateTribeData,player not in tribe when re login to the game

You could check if asps->MyTribeDataField() is not null and is same tribe id as you created, and then you could call asps->MulticastProperty(FName("MyTribeData", EFindName::FNAME_Add));

oo,asps->MulticastProperty(FName("MyTribeData", EFindName::FNAME_Add)); I tried , although I don't know what means

Did it crash the client?

3:35 PM

Multicast basically mean force update the property to clients, so it is known to them almost instantly

yes,crash the client

Interesting

3:40 PM

Try asps->ForceReplicateNow(false, false) or asps->ForceNetUpdate(false, false, false)

both of these can be run correctly,but player still not in the tribe when re login

3:51 PM

oh, if asgm->GetOrLoadTribeData(tid, tribeData) first is false, this func is right.

4:04 PM

but if true, player not in tribe when re login

It's weird, with the decay project if I get the ark option when compiling

8:31 PM

but i still get the same error in the console

@Pelayori Is there any other way to join the tribe?

Last time I was tackling that force create tribe function I didn't get it to work fast so I switched to another approach. What I did is hook game mode::generate tribe id and when I wanted, I would use a global var with the tribe id I wanted, then you can call player state->serverrequest create tribe and that new tribe will have the wanted tribe id

create tribe is run right,but make a player to offline tribe(AddToTribe) has a problem

It's ark quirks, and I do not know if any dev has overcome then, from what I know that is a bug that isn't fixable

AddToTribe and asps->ForceNetUpdate(false, false, false); ,I find Player in tribe,but re login its not in tribe.

What I know it works is: Call player_state->ServerRequestCreateTribe_Implementation() Hook gameMode::GenerateTribeId and return the tribe id you want (must handle post return var states, etc...) if you want to add any other player to tribe, wait till they are online and use add to tribe after get or load data

emmm

8:51 PM

I have successfully created a tribe. The problem now is to join the player

8:53 PM

so hard

I know what have you done and I have told you why it doesn't work

bool  Hook_ADroppedItem_IsAllowedToPickupItem(ADroppedItem* _this, APlayerController* PC)
{

ArkApi::GetHooks().DisableHook("ADroppedItem.IsAllowedToPickupItem", &Hook_ADroppedItem_IsAllowedToPickupItem);

Thank you

Someone can tell me how to judge whether the ADroppedItem is generated by player or AI? Please

actor will never be a controller

10:49 PM

You can use actor->GetOwnerController(), if it's a APlayerController it's a player, else is AI

                                             });

so this for add chat command right ?

Yes, but that isn't the best practice

10:02 PM

I would extract the command function to its own function, and then just register the callback with &FunctionName

I would extract the command function to its own function, and then just register the callback with &FunctionName

wait a sec i think i have to recap and watch any C++ tutorial again because i think dealing with js and lua makes me forget it

10:04 PM

so any recommendation ?

10:04 PM

for good C++ course

10:04 PM

and if it is related to games or ark it would be nice

I do not have any recommendation tbh, just basic C++ and going trough open source plugins was what I did at first, and worked out well if you put the time it needs into learning

so u dont have any recommendation for any c++ basics course

10:06 PM

for me to recab from it ?

I do not, no

Just putting it out there: You don't even have to define DllMain() in your plugins or worry about its potential safety issues. If your DLL exports Plugin_Init() or Plugin_Unload(), ArkServerApi calls them for you after loading your DLL or on unloading it.

c++
extern "C" __declspec(dllexport) void Plugin_Init()
{
...
}

extern "C" __declspec(dllexport) void Plugin_Unload()

Is there is a command i can run to reload my plugin ?

ArkApi has commands to load and unload your plugin on demand. That was discussed recently in one of these channels. If you want a reload command, you have to implement it yourself.

Basically unload my plugin and then remove it and copy another version of it then load the new plugin

9:03 PM

Will be enough for me

9:05 PM

But if i did this will the plugin be updated to the latest version

9:05 PM

Or the old one will still in cache ?

Yeah you can unload your plugin, replace the DLL with your new build. Then load the new version without restarting the server.

in fact, you should have the smallest DLLMain possible

9:26 PM

as doing a lot of stuff in DLLMain is considered anywhere from bad practice to straight up unsafe

9:27 PM

if for some reason you want to write everything inside of DLLMain, you can create a thread inside of DLLMain (this is considered kinda unsafe) and you won't have any issues

9:27 PM

because that thread won't begin executing until DLLMain releases the loader lock

substitute

if for some reason you want to write everything inside of DLLMain, you can create a thread inside of DLLMain (this is considered kinda unsafe) and you won't have any issues

the reason it works (but is unsafe) is because Windows always loads kernel32.dll by the time your dll is loaded.

9:28 PM

but Windows does not guarantee this behavior

9:28 PM

you also risk deadlocking DLLMain if you're not careful

I updated it for VS 2022

bec i tried to use it with vs 2017 (edited)

9:33 PM

but i got bunch of errors (edited)

?

9:34 PM

It was updated for 2022, the readme wasn't updated

9:34 PM

as that's the IDE I use

its ok i will try the older version then

9:34 PM

till the 2022 install

9:35 PM

i think its better to wait

9:35 PM

xD

so when i make the build

10:36 PM

the setting is for the debug mode (edited)

10:36 PM

or for the release mode (edited)

10:36 PM

in ur template ?

SR

in this template

10:38 PM

bec it works good in the debug but on the release i got some errors related to windows SDK

10:38 PM

i have the sdk 11

10:38 PM

and the setting is set to 10

10:38 PM

so i am going to download 10

10:38 PM

and try again

this is the err i got when i changeed from debug to release

11:04 PM

in the template

11:04 PM

while the debug has no problems

I'm more of a Linux guy not a Visual Studio expert at all, you probably want to look through the config options and check out the differences between the debug and release build. For me personally, a recent Visual Studio update seemed to break ArkServerApi headers from compiling on v143 and I had to switch it back to v142, but I didn't look into what the issue was. (edited)

so we cannot use the debug build in the server right ?

You might be able to, it might be slower or have side effects depending on how it was written and compiled

finally solved

11:15 PM

best message in my day

11:15 PM

OMG

11:16 PM

i will just have to test it tomorrow and start working my way to the mysql stuff that will be linked to the plugin

11:16 PM

thanks all guys

Is there any way to prevent fjordhawr picking up death item cache?

You want to stop Fjordhawk from picking up and returning its owner's death cache to them when they respawn? Or you want to prevent Fjordhawk from carrying other creatures' item caches to the player? You can probably prevent either one from happening with plugins, but there may be some things you can't disable without mods, like the death cache return cool down icon on the player's screen.

dont know where else to ask but after i installed the arkserverapi i get this message when loading

The L means the string uses wide characters instead of the usual 8 bits.

try this FString m1 = FString(fmt::format(" {}", strText));

I did that, this is the error

m1 is an FString?

8:24 PM

You need the inner c string buffer

8:25 PM

Also if you’re going to use wide chars

8:25 PM

You need wstring not string

Use your original line then use m1.c_str() I believe

substitute

m1 is an FString?

yes

Then use c_str()

nothign seems to work.. i may just use std:: string replace instead

The api doesn’t have all conversions defined for string and fstring so you don’t get this for free

substitute

Then use c_str()

tried that

jraServerAPI

tried that

Post your exact code

8:27 PM

The entire method and I’ll download my template and make it work

substitute

The api doesn’t have all conversions defined for string and fstring so you don’t get this for free

@Lethal this is something we could also do to improve the api

8:28 PM

Adding conversions between STL strings and FStrings

Oh it’s TCHAR and not wchar_t

8:29 PM

Honestly I’d just use the STL for this

FString m1 = FString(fmt::format(" {}", strText));
message2 = message.Replace(*m1, L" ");

this is what i got thus far

c++
                        std::string strText = " random";
                        FString m1 = FString(fmt::format(" {}", strText));
                        FString m2 = FString(fmt::format(" "));
                        bool isRandom = message->Contains(m1);

                        if (isRandom)
                        {
                            message2 = message->Replace(m1, L" ");
                        }

Convert the FString to wstring

8:29 PM

Do all your operations

8:29 PM

Convert to FString

i just want to look for a flag on the chat "command line" and remove it from the FString

8:30 PM

Replace is picky lol

Yeah, it might be easier to do that on a wstring

okay.. thank you for all you help

happy holidays everyone

Also don’t use std::string

8:31 PM

Use std::wstring

8:31 PM

I’m fairly certain UE4 is UTF-16

1

Can you elaborate?

Did you try my last code?

what happens if use std::string? Oh lethal i didnt see it.. gonna try it now

8:35 PM

I didnt get any red squiggley lines Lethal

8:35 PM

I'm gonna compile and test

I thought ArkApi's FString::ToString() was smart enough to give you a std::string regardless of which format the FString used. I'd have to double check though. I hate working with strings.

It does do that but FString::Replace() wants Const TCHAR

I see

Donsora

Is there any way to prevent fjordhawr picking up death item cache?

Well I took a shot at preventing the Fjordhawk from returning a player's items on respawning because it sounded fun. In any case, all this Fjordhawk stuff is defined in Blueprint graphs that you can view in the ARK Dev Kit. That's where you should go to figure out what you need to change. Open the Fjordhawk_Character_BP_C blueprint in the dev kit. Note the package name when you hover over the blueprint in the Content Browser (/Game/Fjordur/Dinos/Fjordhawk/Fjordhawk_Character_BP), we'll use that in our plugin.

1

8:39 PM

Looking through the Fjordhawk's functions (under Graphs, once you open the blueprint), Check for Player Death and On Player Died are both interesting, and they're both called by BPOn Clear Mounted Dino. When the Fjordhawk is removed from your shoulder, it checks if you're dead and retrieves your inventory. Check for Player Death runs on the server and kicks off a chain of events that makes the Fjordhawk retrieve your inventory and bring it back to you. On Player Died runs on the client and just removes the player's equipped items, which I don't think matters to us. So if we prevent Check for Player Death from running on the server, the Fjordhawk won't return our inventory. Functions defined by graphs in the dev kit can't be directly hooked natively, but we have other options.

8:39 PM

Inside our plugin, we need to find a couple of Unreal Engine objects: The UClass that represents the Fjordhawk class, and the Check for Player Death UFunction. UVictoryCore::BPLoadClass() is one option for looking up Blueprint classes. This function takes an FString that includes the blueprint's package plus the blueprint's name:

c++
FString path = "Blueprint'/Game/Fjordur/Dinos/Fjordhawk/Fjordhawk_Character_BP.Fjordhawk_Character_BP'";
UClass* hawkClass = UVictoryCore::BPLoadClass(&path);

Note: BPLoadClass() shouldn't be called until after the server has initialized. Classes aren't initialized yet when ArkServerApi first loads plugins. To find the UFunction, we want the function's actual name in the game engine, which doesn't always completely match the names we see on the graphs. One option is to get the real name from the dev kit by hovering your cursor over the function name in the "My Blueprint" tab (left hand side of the previous image). Or you can use something like this to dump a class's UFunction names from a plugin:

c++
void ListFunctions(UClass* Class)
{
    if (!Class)
        return;

    for (TPair<FName, UFunction*> pair : Class->FuncMapField())
        Log::GetLog()->info(pair.Key.ToString().ToString().c_str());
}

It turns out that Check for Player Death in the dev kit is called CheckForPlayerDeath in the game.

8:39 PM

So in our plugin, we're going to: 1. Hook AShooterGameMode::BeginPlay(). This function is called once after the game has been initialized, this is where ArkServerApi sets ServerStatus::Ready. At this point we can look up the UClass and UFunction we need and save the UFunction's unique InternalIndex to compare against later. 2. Hook UObject::ProcessInternal(). This function is used by Unreal Engine to execute UFunctions that are defined by graphs in the dev kit. One of the arguments passed into ProcessInternal() is an FFrame*, the current UFunction's call stack frame. We can use the FFrame to get a pointer to the UFunction that is being executed, and then block CheckForPlayerDeath from executing. ArkServerApi doesn't provide FFrame, we need to define it ourselves (I've posted a more complete definition of it before in this Discord).

8:39 PM

can i use api when renting server or only dedi servers u can use them on ?

never mind

hello guys i was just now try to check some api files

bec from what i know there is no tech difference between them other than the backward compatibilty with C and the visibilty things

i mean why is it is there is any specific reaseon ?

Best guess I got: Maybe it's just to slightly reduce the size of all that generated header code. All those public:s that would be required for classes really add up lol, especially if additional game classes were to be added to the API

i would suggest you compare your "kit" config, to the default "kit" config that came with the plugin.. character by character, and you will discover what is wrong.. Are you familiar with json? if not, i would learn that first (edited)

thx, i love learnings this so thx for the link

google and youtube should be your best friend

5:59 PM

before you come here and ask

5:59 PM

yeah i do that and fixed the problem i got, only problem i have now is the end of coding, havent touched that either from original, so dont now why i get a error on that one XD

ok guys i am justt want to know where does all world objects are stored

6:03 PM

and how can i retrive them back

6:03 PM

if i want to loop over them or so

c++
TArray<AActor*> FoundTurrets;
UGameplayStatics::GetAllActorsOfClass(ArkApi::GetApiUtils().GetWorld(), APrimalStructureTurret::GetPrivateStaticClass(), &FoundActors);
for (const auto& Turret : FoundTurrets)
{
    auto TheTurret= static_cast<APrimalStructureTurret*>(Turret);
    if (TheTurret)
    {
        // do the thing
    }
}

6:17 PM

i think this will work

jraServerAPI

actually i found the function but it was for dinos

6:35 PM

so i will try my luck with it on the turret

6:35 PM

xD

i know haha "do the thing" is what i wrote hahaha

I am curious about how to connect the plugin I made to the ark api server

that will work tho

xDDDDD omg

6:38 PM

thats huge

6:38 PM

hahaha

아

I am curious about how to connect the plugin I made to the ark api server

u have to copy it and put it in the plugins folder of the ark api

I downloaded the ark template file from Github, do I have to put all of them in?

u have to build it first

Can you tell me how to build it..?

and get the .dll file and the GxFirstPlugin.pdb

where do you get that from?

oh i think u have to start learn C++ first

6:41 PM

so u can do it

I am new to API connection

6:41 PM

I know how to do c++

then just build ur project as u are building c++ dll file

blackandbuewolf

yeah i do that and fixed the problem i got, only problem i have now is the end of coding, havent touched that either from original, so dont now why i get a error on that one XD

You dropped a closing } or ] most likely

아

where do you get that from?

When you build the project you’ll get a dll.

so basically when i get the turrets

6:47 PM

how can i get the amount of ammo in the turret ?

Should I put the dll inside the plugin folder?

TheMollusk

Well I took a shot at preventing the Fjordhawk from returning a player's items on respawning because it sounded fun. In any case, all this Fjordhawk stuff is defined in Blueprint graphs that you can view in the ARK Dev Kit. That's where you should go to figure out what you need to change. Open the Fjordhawk_Character_BP_C blueprint in the dev kit. Note the package name when you hover over the blueprint in the Content Browser (/Game/Fjordur/Dinos/Fjordhawk/Fjordhawk_Character_BP), we'll use that in our plugin.

Got it thank you very much.

this show up on me and server wnt start, yes my coding have no errors on it. tried google and everything.

10:40 PM

[ArkShop][error] [json.exception.type_error.306] cannot use value() with null

2:43 PM

cant find any info on this on google or yotube

do someone here know where i can remove engrams from a mod, tried the game.ini but dont work

why is this a beginner chat when no one is answering ? this discord channel is not good for any. dont write beginner and no one wanna help the beginners. damn. but dont worry, got a friend that helped me and i understand more now.

why are you in a developer's discord and asking on how to setup a plugin's config? Beginners chat is for coders not for issues you have with you fine working plugin that we gave you for you to manage. (edited)

is there is a way that i can make a plugin runs specific RCON Command ? (edited)

i mean if i have a RCON command that is registred in another plgin

3:32 PM

and i want when i player type specific command in chat

3:32 PM

to execute this RCON command

3:32 PM

after some check that i will create

3:33 PM

what is the way that i can do this ?

NT Diesel

is there is a way that i can make a plugin runs specific RCON Command ? (edited)

Just to make sure I'm understanding, do you need to run an RCON command (handled through the game's RCON server) or is running a console command (normally typed into the client's game console) sufficient? ArkServerApi handles them differently. It's not uncommon for plugins to register the same commands for RCON and the client console.

listen i am using certain plugin which makes the orb the plugin wrote by @Lethal

6:12 PM

but i dont want the admin to write the command for the tribe

6:13 PM

i want the player to write the player by him self

6:13 PM

and he will be able to take the protection for only one time

6:13 PM

which i will handle through tribe_id and database

6:13 PM

but the plgin uses RCON command

6:13 PM

lethalorp.raidprotection <add/remove> <tribeid> <hours>

6:14 PM

so i want to execute this rcon command from my plugin whenever a player is typed another chat command

6:14 PM

for example when any playe write eg:- /getmyorb

6:14 PM

it will check on its tribe id which i already did

6:14 PM

if he deserve the protection so trigger this RCOn command

6:15 PM

lethalorp.raidprotection <add/remove> <tribeid> <hours>

This is a developer discord not end user support. You cannot do what you are asking for currently as RCON commands are meant for admins not users since you need to be authenticated.

Lethal

if i do my own route handler as if i am using external web server and i made this server send the rcon command it will work right ?

I could add a console command which would allow selling a 1 time protection command or something maybe but you can put in a suggestion for it on my discord.

6:18 PM

Sure, but seems like a lot for a simple thing.

cannot u share ur source code with us ?

6:19 PM

i mean ur plugin is already open source

Lethal

Sure, but seems like a lot for a simple thing.

yup

6:19 PM

ok i will post this to ur discord now

Free does not mean open source

Lethal

Free does not mean open source

yup mb but i mean its just for educational purpose xDD

7:03 PM

its ok i am gonna wait ur feature till then i will make my own route for the rcon command

I'm not going to comment on specific plugins, but developers certainly have legitimate uses for invoking console/RCON commands based on player actions. I've done both. RCON was a little more involved, I didn't use any shortcuts, just regular RCON protocol. Console commands are easy though. Chat command in Plugin1 invoking console command in Plugin2:

c++
// Plugin1.cpp
#include "API/ARK/Ark.h"

#pragma comment(lib, "ArkApi.lib")

void FooCmd(AShooterPlayerController* spc, FString* input, EChatSendMode::Type)
{
    ArkApi::GetApiUtils().SendServerMessage(spc, FColorList::Green, "FOO");

    FString result;
    FString cmd = "bar";
    spc->ConsoleCommand(&result, &cmd, false);
}


extern "C" __declspec(dllexport) void Plugin_Init()
{
    Log::Get().Init("Plugin1");

    ArkApi::GetCommands().AddChatCommand("/foo", FooCmd);

u use any external plugin for the RCON ?

7:24 PM

i mean any external library ?

7:24 PM

i will use this https://github.com/Phil25/SourceRCON/blob/master/include/srcon.h

SourceRCON/srcon.h at master · Phil25/SourceRCON

C++ Source RCON implementation. Contribute to Phil25/SourceRCON development by creating an account on GitHub.

Behind the scenes ARK executes console commands when an RCON command is received IIRC.

7:32 PM

That is for the built in ARK commands anyways. That doesn't apply to plugin commands.

Lethal

That is for the built in ARK commands anyways. That doesn't apply to plugin commands.

u mean that triggering ConsoleCommand Can act as RCON command ?

7:33 PM

for native ark commands ?

NT Diesel

i mean any external library ?

That's what I used. On a separate thread to avoid potential hangs. It was in a Linux plugin though, the GitHub page says it's Unix only.

TheMollusk

That's what I used. On a separate thread to avoid potential hangs. It was in a Linux plugin though, the GitHub page says it's Unix only.

do u put them in the plugin folder or just include them as the api ?

NT Diesel

do u put them in the plugin folder or just include them as the api ?

It was compiled directly into my plugin. Like I said though, you'll need a different solution or different library on Windows for ArkServerApi plugins.

NT Diesel

u mean that triggering ConsoleCommand Can act as RCON command ?

I'm saying native ARK rcon commands are translated and trigger an associated console cheat command behind the scenes.

TheMollusk

how can i make post or put request and wait its response with api is this possible ?

Lethal

oh i see

7:42 PM

i can handle the rcon on my node.js server

7:42 PM

there is a package for this

Plugin RCON commands do not map like that and the plugin needs to create handlers for both RCON and Console and can make the RCON code execute the console version of it. But not all commands make sense to use as both so for instance I have some commands that are console only and some that are rcon only and others that are both.

yup it works thanks

guys does Turret.stasis() make the turret inactive or in off state ? (edited)

10:27 PM

which means wont attack any target ?

turret targeting is actually controlled on the Players and dinos, what are you trying to do?

i want to set the turret to sleep state

10:28 PM

which will make them wont attack any target

10:29 PM

i am creating my own turret manager

10:29 PM

with help of great guy @dougy open source filler turret i managed to get some ideas that helped with the auto filler

You need to turn off targetting on the players/dinos etc...

u mean using BPTurretPreventsTargeting ?

A lot of the turret stuff is implemented in Blueprint, might need to investigate in the dev kit. I believe the Stasis() function is called on actors that go into stasis when there are no players within render distance (some distance at least, idk the details) of the turret, which probably isn't what you want. (edited)

NT Diesel

u mean using BPTurretPreventsTargeting ?

no, bPreventTargetingByTurrets

jraServerAPI

no, bPreventTargetingByTurrets

but this will apply the state on all turrets in the game right ?

10:34 PM

not only specific turrets

NT Diesel

but this will apply the state on all turrets in the game right ?

this is a boolean on the player and dinos

10:35 PM

it tells the turrets not to shoot at it

jraServerAPI

it tells the turrets not to shoot at it

but it tells all turrets

10:35 PM

not specific turret

I'm not aware of a way to stop the turrets from shooting any other way.. unless you remove the ammo

NT Diesel

but it tells all turrets

yup

give alook into BPTurretPreventsTargeting

10:37 PM

TheTurret->BPTurretPreventsTargeting()

10:38 PM

but it takes APrimalCharacter which means i have to pass all dinos and all players or is there is any way to pass all struct members at once

i would test it out on 1 dino first..

10:39 PM

to make sure it works

i dont think its the one i need

10:43 PM

bec it will only disable it

10:43 PM

and there is no way to enable it

10:43 PM

there is an option in the native game

10:43 PM

when press to E to set the turret to on and off

10:44 PM

oh i found it (edited)

10:44 PM

c++
TheTurret->IsValidToFire(true) // to make it on
TheTurret->IsValidToFire(false) // to make it off

(edited)

10:47 PM

and for selecting specific targets to be valid

10:47 PM

i think i can use hook

10:49 PM

c++
DECLARE_HOOK(APrimalStructureTurret_SetTarget, void, APrimalStructureTurret*, AActor*);

void  Hook_APrimalStructureTurret_SetTarget(APrimalStructureTurret* _this, AActor* aTarget)
{
if(){// check if the target is within specific class eg dino
  return APrimalStructureTurret_SetTarget_original(_this, aTarget);
}
else{
  return 0;
}

}

ArkApi::GetHooks().SetHook("APrimalStructureTurret.SetTarget", &Hook_APrimalStructureTurret_SetTarget, &APrimalStructureTurret_SetTarget_original);

you can try it, but i think that hook gets called every tick, so it's pretty busy

bPreventTargetingByTurrets you set on each turret.

Lethal

bPreventTargetingByTurrets you set on each turret.

Example please

11:06 PM

If i have turret stored in Turret variable

Turret->bPreventTargetingByTurrets().Set(true);` (edited)

but that's not a property for turrets or structures, only players and dinos

oh true

Its for characters only i think

Just grab all the player and dino actors in the world and set that bool when you want to disable and enable turrets

jraServerAPI

you can try it, but i think that hook gets called every tick, so it's pretty busy

Every tick ?

11:10 PM

Thats bad

it is

jraServerAPI

Just grab all the player and dino actors in the world and set that bool when you want to disable and enable turrets

What if new player join

11:10 PM

Then i have to use hook for this

there's a hook for that

And add this player to the TArray

11:11 PM

Or wait

also when dinos spawn..Begin Play hook

Just prevent its targeting

yep

11:11 PM

start coding

11:11 PM

get your hands dirty

11:11 PM

test test test

I hate C++ xD

thats what we all do.. gatta figure it out

jraServerAPI

thats what we all do.. gatta figure it out

But i will try C++c++ TheTurret->IsValidToFire(true) // to make it on TheTurret->IsValidToFire(false) // to make it off First

good luck!

jraServerAPI

good luck!

Really thanks for ur time bro ❤️

guys i just wanna ask question but i think its silly one

12:36 PM

c++
//this is my .h file
TArray<ProtectedBase> AllProtectedBases = TArray<ProtectedBase>();

12:37 PM

how to add a new element to this array in my init.cpp and make this element exist in all other .cpp files

12:37 PM

shall i do

c++
AllProtectedBases.Emplace(MyBase);

12:37 PM

only ?

12:37 PM

or shall i use the reference operator ?

12:38 PM

c++
&AllProtectedBases.Emplace(MyBase);

12:38 PM

like this

Can we nest TMaps ?

NT Diesel

Can we nest TMaps ?

Yes

shall i do

Use this

Thanks bro

A TMap is just a map of any Types

Nvm i am gonna create TMap of TArray of struct i think it will do the job for me

while i try to build the plugin using mysql

12:10 PM

i copied the premission mysql files and includes

12:11 PM

12:12 PM

12:13 PM

thats the files i include and the lib files

12:13 PM

but it gives me strange err

12:13 PM

any help ?

NT Diesel

Click to see attachment 🖼️

this is the err

or does any one have a good template with ark api and the mysql like the one that @substitute have ?

2:17 PM

so i can use it

2:18 PM

but it will be better if its for vs2022

You will need to look at ArkShop for that.

Lethal

You will need to look at ArkShop for that.

Actually i copied all ark shop includes and lib folder

2:43 PM

And copied the structure of the IDatabase and MySql

2:43 PM

And i got this error

2:43 PM

It only appear on building

Include mysql++11.h to your project

Foppa

Include mysql++11.h to your project

actually i did include it

7:22 PM

let me show u

7:22 PM

i am including this file

7:22 PM

7:23 PM

and in it i include the mysql++11.h

include it as a part of files

Foppa

include it as a part of files

u mean in the headers option in workspace properties ?

no

7:28 PM

as in your solution of files

same error

printscreen?

And your solution settings

7:34 PM

any one got any idea ?

Well first you should put the Ark header include in your IDB header

8:55 PM

also look in arkshop or permission plugin for reference

the problem is i am using the same build for every thing as permission

8:56 PM

but my vs is 2022

8:56 PM

i also tried to lower my setting of my vs to 2019

That's not a problem

and still same error

8:57 PM

can u make template with arkapi and mysql or something like this ?

you already have them?

i have the template of @substitute

8:58 PM

but my problem is in mysql

8:58 PM

cannot get it to work

8:58 PM

but i have created some plugins without mysql

8:58 PM

and its working

well it indicates an error in a file from the mysql includes, perhaps tidy up your includes (edited)

9:00 PM

Also another thing, try drag the whole folder of files for mysql

9:00 PM

could solve some cases

omg

9:02 PM

the problem was in the order of includes

9:02 PM

wtf

yes, it can confuse the compiler sometimes

guys what is the best way to store FVector to mysql database? (edited)

is there is any other way than saving the x, y, z each indvidually ?

Easiest way is to save a string with x,y,z separated with a comma each, so then you can split with , separator and parse the floats with std::stof, for example

Pelayori

Easiest way is to save a string with x,y,z separated with a comma each, so then you can split with , separator and parse the floats with std::stof, for example

the problem is the FVector compononets are large

11:12 PM

i cant even print them with ARK API Log (edited)

That doesn't matter. You could truncate them to 2 decimal places

FVector::ToString does it, for example

FVector::ToString separate them with commas or spaces or what ?

ToString formats it like: X=xxx Y=yyy Z=zzz or so, you can look it up

11:14 PM

FString::Printf("X=%3.3f Y=%3.3f Z=%3.3f", X, Y, Z); that's what it does (edited)

so i can replace the white spaces with commas

11:16 PM

and then remove X, Y, Z and equals

11:16 PM

and save this value to the database

11:16 PM

then on i will split on the commas

Yes, you could. I would as well remove X=, Y= and Z= strings so you don't have excess characters

NT Diesel

then on i will split on the commas

Basically, that'd be an easy implementation

let me write the code and check if i could write or not

Pelayori

Basically, that'd be an easy implementation

c++
FString pos = position.ToString();
            pos.Replace(L"x", L"");
            pos.Replace(L"y", L"");
            pos.Replace(L"z", L"");
            pos.Replace(L"=", L"");
            pos.Replace(L" ", L",");

11:26 PM

what do u think?

c++
db_.query(fmt::format("SELECT steamid, position, radius, startdate, enddate FROM {}", table_protections_)).each([](int tribeid, const FString* position, FString radius, time_t startdate, time_t enddate) { // there might be problem bec of FString of position and radius here

                TArray<FString> parsed;
            
                position->ParseIntoArray(parsed, L",", true);

                FVector BPosition = FVector(FCString::Atof(*parsed[0]), FCString::Atof(*parsed[1]), FCString::Atof(*parsed[2]));

                ProtectedBase MyBase(BPosition, FCString::Atof(*radius), tribeid, startdate, enddate);
                AllProtectedBases.Emplace(MyBase);
                return true;
            });

11:41 PM

is this good way to do this ?

11:42 PM

note the position and radius are of type varchar in data base

11:47 PM

i am new to mysql in c++

11:47 PM

but i dont know how to set the type of the coming values

Pelayori

Easiest way is to save a string with x,y,z separated with a comma each, so then you can split with , separator and parse the floats with std::stof, for example

I would store them as three decimal numbers

5:58 AM

Truncating reduces accuracy

5:59 AM

Strings are also slow in database terms

Stack Size Overrides: Are these values stored somewhere separately and not in the item? Because when I check the UPrimalItem::MaxItemQuantityField() of one of these items in my inventory, it returns the default/vanilla values for some reason (100) and not 1000 like I would expect. Thanks

ArkServerApi provides TArray<FItemMaxItemQuantityOverride>& AShooterGameState::OverrideItemMaxQuantityField(), which I would guess is where the Game.ini overrides are held. FItemMaxItemQuantityOverride isn't defined though, so you've got a little extra work to do. (edited)

regarding Hook_AActor_TakeDamage is there is any huge diff between the event instigator and damage causer ?

2:21 PM

or just use the damage causer ?

2:21 PM

bec based on what i have understood there is no huge difference and there are some time where event inst is null but the damage causer is never null

The event instigator can be null if the damage wasn't caused by a controller (player/ai controller). The damage causer could also be null, but in less cases. It depends on what you need. If you need the actor of the damage go with the damage causer, if you need the player who did it (like steamId, etc) go with event instigator

yep, just check ark shop source, console version does no return anything, rcon version does

I am trying to find a way to execute RCON commands from the API. Perhaps some kind soul can point me in the right direction? The only alternative I've could think of is to make a RCON client inside the plugin.

You can actually make ur own webserver and send a request via api to it so u can make rcon command

8:26 PM

U can easily make it with express js and nodejs as backend server

8:27 PM

And use any plugin that allow u to contact with rcon through node js

A good module for ur express is node-rcon (edited)

Hi, I have a small question I am sending a HttPostRequest and I need to evaluate the response of this request but I am not quite sure how to do this, any ideas would be of great help.

Do you have an example on what you are trying to do?

Hi, sorry I just got off work. I recently made a mod that does the same thing I want to do now with the plugin I don't know if it will work for you as an example. However, a bit of context would be that I am using HTTPPostRequest to send something to an api, this api when it receives the data returns a status to inform the user if the process was successful, then I want to somehow evaluate that status in the request response so I can return to the player a message that the process was successful or otherwise an error occurred.

Hey, I'm trying to give better taming to single players. The only real approach i could come up with was to change the affinity a dino needs but I can only tell which team knocked it out not the specific player. Before I try to build something more complicated that would try to track who attacks what I just wanted to ask if I maybe overlooked some simpler solution.

In case someone is wondering, there is an OwningPlayerIDField and OwningPlayerNameField on APrimalDinoCharacter but that was empty for me if the player is in a tribe.

I'm not sure if it tracks the player that knocked it down

Maybe there is another way to achieve my goal but I could not really find other ways to influence the taming process which would not be server wide.

Original message was deleted or could not be loaded.

APrimalStructureItemContainer doesn't have a property named "CurrentResourceCount". You want to get the UPrimalInventoryComponent associated with the bag and get the item count from that. Something like int count = bag->MyInventoryComponentField()->GetCurrentNumInventoryItems(); where "bag" is a APrimalStructureItemContainer. Also, there's no reason to use UObject::FindProperty() or UProperty::Get()/Set() unless you're working with Blueprint generated classes. APrimalStructureItemContainer and UPrimalInventoryComponent are native classes. Just use the definitions in the API headers to access properties, those accessor functions are faster.

There you go. Technically the player character is either a APlayerPawnTest_Male_C or APlayerPawnTest_Female_C. The full inheritance is

APlayerPawnTest_Male_C > APlayerPawnTest_Child_C > APlayerPawnTest_C > AShooterCharacter > APrimalCharacter > ACharacter > APawn > AActor > UObject

. Classes that end in a "_C" are blueprint generated. ArkServerAPI headers just have definitions for native classes like AShooterCharacter.

LastControllerField() gives you a TWeakObjectPtr<AController>. Which you need to use either Get() or -> on. You should read the code in the ArkServerApi headers to figure some of this stuff out and probably become a little more familiar with C++ (edited)

And there's a very good chance that if they are logged out their controller isn't valid and you'd be dereferencing a nullptr.

Is there a hook that works when a character is regenerated or deleted?

help. Is there really no hook when deleting a character?

6:43 AM

I looked... but couldn't find it.

I think "deleting" a character is just overwriting your current character on server with a new one.

6:47 AM

You might be able to hook the function responsible for creating a new character and check the data passed in there

6:47 AM

I believe it's AShooterPlayerState*

6:47 AM

But I can't recall for sure off the top of my head

6:48 AM

I don't think AShooterPlayerState has a way back to a controller or character though so you might have to compare ID's on server or something like that. (edited)

okay, one dude more is there any way to modify RandomMutationChanceField() and MaxAllowedRandomMutationsField() from a Fertilized egg?

I've never tried nor do I know the effects of what happens if you do but you should be able to overwrite it on the server with a plugin.

If i am using the following code in

case DLL_PROCESS_ATTACH:
if (ArkApi::GetApiUtils().GetStatus() == ArkApi::ServerStatus::Ready) {
Log::GetLog()->info("Called Load_Something");

load();

it should run load_something() after the server is booted up, but it never called it, am i missing something? i also tried to != and return it within the load();

Solved just hooked into begin play to call the method

no, this will only run if you load the plugin after the server has booted

how i can do like verify system in my plugin?

use API requests or if that doesn't suit your needs include something like cpp httplib to have your own requests library

but in this case you'll have to write the threading code for your requests yourself, since performing the request itself inside the main thread will hang the server for a considerable amount of time

def still an issue, eating me alive tonight. but might not be possible to fix as i assume the issue is the client has a smaller expected max buffer size than the serverfor total data payload is what triggers the issue, and client needs to sync to match possibilities from the server, but of course its ark, they wont fix simple things like that.

7:48 AM

or net code has to be rewritten to chunk the data, like ark data has a play in it too, so i assume they are just allocating 1 giant packet.

7:50 AM

this data is loaded early too, as i once boosted the # of items you can store in arkdata, and a player filled it with fert eggs, and totally broke his ability to even login, not just transfer. the only way i could recover him was to set the max expiration time to a short time to cause some of his items to expire.

Hi, I was wondering if there is a way to do something with blueprint functions like trigger the execution. I assume the local variables inside a bp function are off limits, but some bp functions change properties which are accessible. Hence something like "trigger bp function" -> "read property" could be possible. No idea how to do it tho^^ If it isn't a little hint as to why would be appreciated.

you are able to call blueprint functions

9:21 PM

you find it by name inside an object pointer and then you use ProcessEvent to invoke the function with any parameters you want to pass into it

You can call and hook Blueprint functions. You can also access input/output arguments and local variables inside your hook. Blueprint functions (and many native functions) are represented as UFunction objects. We can find UFunctions by calling UVictoryCore::BPLoadClass(FString* PathName) to get the UClass the function is defined in, then find the function itself with UClass::FindFunctionByName(FName InName, EIncludeSuperFlag::Type IncludeSuper). Here's an example that uses the Blueprint function Buff_Companion_HLNA_C::Get Glitch Mission Complete Count(). This function returns the number of glitches that a player has collected in a given Gen1 biome. It has FName MissionTag and AShooterCharacter* Player input arguments, an int32 Count output argument, and an int32 ret count local variable.

HLNAExample.cpp

12.35 KB

9:57 PM

The example code installs a /test chat command that calls Buff_Companion_HLNA_C::Get Glitch Mission Complete Count() to get the number of glitches the player has collected in the Bog biome. To call a Blueprint function, we call [UObject,AActor]::ProcessEvent(UFunction* Function, void* Parameters). Function points to the function we want to call. Parameters points to memory that has the input/output arguments all packed together (defined by struct GetMissionCompleteCountParms in the example). The example also hooks the Buff_Companion_HLNA_C::Get Glitch Mission Complete Count() Blueprint function by hooking UObject::ProcessInternal(UObject* _this, FFrame* Stack, void* const Result). Unreal Engine uses ProcessInternal() to execute the bytecode of a Blueprint function. When ProcessInternal() is hooked, we can hook specific Blueprint functions by checking which UFunction ProcessInternal() is being called on. Each Blueprint function that is executed has its own FFrame stack frame object. We can use ProcessInternal()'s Stack argument to access input/output arguments and local variables inside our Blueprint function hook. When the Buff_Companion_HLNA_C::Get Glitch Mission Complete Count() hook in the example is executed, it prints the name of the AShooterCharacter* Player input character and the value of the int32 ret count local variable. We can also examine previous function's frames on the stack. For example, we can see which Blueprint function called the hooked function and access the caller's variables. The example code demonstrates this by hooking the native function AMissionType::FindMissionsMatchingTag(), and the Blueprint function AMissionType_GlitchCounter_Base_C::GetCompletedGlitchCount(), both of which are called by Buff_Companion_HLNA_C::Get Glitch Mission Complete Count(). These hooks print input and local variable values from the calling Buff_Companion_HLNA_C::Get Glitch Mission Complete Count() function.

@TheMollusk if anyone is prepared for this it would be you

10:08 PM

you can step a FFrame

FFrame::Step

Functions.

FFrame::PeekCode

Returns the current script op code

Yeah if you want to get fancy you can modify the Blueprint UFunction bytecode and do things like change the values of const local vars. Or insert a UFunction call at a specific offset.

the uint8* code is the current instructions

10:14 PM

    /** Returns the current script op code */
    const uint8 PeekCode() const { return *Code; }

these are also bothersome

10:21 PM

    EX_PushExecutionFlow    = 0x4C, // push an address on to the execution flow stack for future execution when a EX_PopExecutionFlow is executed.   Execution continues on normally and doesn't change to the pushed address.
    EX_PopExecutionFlow        = 0x4D, // continue execution at the last address previously pushed onto the execution flow stack.

10:22 PM

maybe I dump some code from the game to see what the bytecode format is

10:22 PM

I assume it is single value instructions similar to IL (edited)

The instructions are actually the EExprToken enum values. Each value is an index into the global Native GNatives[EX_Max] array. This array has pointers to native functions that execute the virtual machine instruction.

c++
void FFrame::Step(UObject *Context, RESULT_DECL)
{
    int32 B = *Code++;
    (Context->*GNatives[B])(*this,Result);
}

yeah, my concern is escaping the virtual environment for native code execution

10:26 PM

like is EX_ComputedJump sanitized for example

10:26 PM

and obviously there is some barrier traversal for BP functions that call into native code that is exposed to BP functions (edited)

substitute

and obviously there is some barrier traversal for BP functions that call into native code that is exposed to BP functions (edited)

The way that works is the bytecode has a EX_VirtualFunction or EX_FinalFunction instruction that calls UObject::CallFunction(FFrame& Stack, RESULT_DECL, UFunction* Function ) with a UFunction address that was evaluated by name or read from the bytecode. Then for native UFunctions, CallFunction() calls the UFunctions Func field, which points to a native void execFoo(UObject* Object, FFrame* Stack, void* const Result), which processes any native function arguments out of the calling functions bytecode and then calls the C++ Foo().

10:42 PM

So if you could modify a native UFunctions Func field, that would be one way to redirect native control.

10:42 PM

But I'm not sure a mod could do that.

Wow. Thank you very much for this detailed answer.

@TheMollusk on an unrelated note

10:47 PM

did you know, that the ... is NOT part of a function signature in C++?

10:47 PM

specifically, std::function can not store variadic functions

Maybe it's possible somehow to get a reference to a UFunction in your bytecode and modify its Func field.

__stdcall void(void) is fine

10:47 PM

as the attribute (calling convention) is part of the signature (edited)

10:48 PM

but you can't do void(...)

10:48 PM

I'm not sure why syntactically as calling conventions aren't even in the standards

No I guess I didn't know all that lol

I take it back actually, __stdcall wouldn't work

cdecl only worked because the macro was defining it to nothing, thanks Microsoft (edited)

If you do it from VS with the project open it should show the specific line

As the crash is coming from the dll directly

It seems you are trying to get the item before it gets added to the inventory

So the item will return null, or some garbage

11:49 AM

Also, you can get the item directly without having to get it from item id in that book

You could do auto item = original hook call, and then in the return you do return item

also you should use FNAME_Find since this string should already exist (edited)

Hi, I continued my journey with ufunction/properties and I thought it was going well until I stumbled across "Buff_CryoCooldown". Acording to the devkit every bpFunction uses a variable TimeLeft which is also a default property. But somehow this property is never set. I tried it inside the hooks APrimalBuff_BeginPlay and APrimalBuff_AddBuff. I checked the class default object and made a test chatcommand that goes through all the characterbuffs and checks for the right buffclass and if the property is set. To check for the property I use (I also tried "Time Left" with space) and its never found.

UProperty* theProperty = buffCryoCooldownObj->FindProperty(FName("TimeLeft", EFindName::FNAME_Find));
if (!theProperty) {
    Dodo::Logg::writeToLogFile(pluginName, "prop TimeLeft not found");
}

There is another Property "DeactivateAfterTime" which I did successfully set in all the methods above and it did deactivate the buff early, although the timer for the player is still 300 seconds it just ends after whatever I set. Now the question is what is going on with this one property, what am I missing^^ (edited)

You aren't missing anything. TimeLeft is the only property in ABuff_CryoCooldown_C. The released version of ArkServerApi has a bug in UObject::FindProperty() where the first property is not included in the search. It's fixed in GitHub, so you can rebuild ArkServerApi from source yourself and it will work. But your plugin wouldn't work for other users using 3.54/3.55. One option is to just compile the fixed FindProperty() in your plugin and use that.

c++
UProperty* FindProperty(FName name)
{
    for (UProperty* Property = ClassField()->PropertyLinkField(); Property != nullptr; Property = Property->PropertyLinkNextField())
        if (Property->NameField().Compare(&name) == 0)
            return Property;
    return nullptr;
}

You aren't missing anything. TimeLeft is the only property in ABuff_CryoCooldown_C.

Thanks again for the answer. I basically just define "my own" (your fixed^^) findproperty function inside the plugin and use that?

Yeah just define it yourself and call that instead of the exported UObject::FindProperty()

One little followup. Everything works now with the property. The only thing interesting is that the client still starts at 300 seconds, even if I set it (on the class default object) to like 20 seconds. It does still work and gets updated "on the fly". I assume its some replication issue. I'm just wondering where the client gets the 300 seconds from because there is as far as I can tell nothing serverside that has 300 seconds as a value I also set the property "DeactivateAfterTime" to 20 seconds. Is the reason that the client uses some local version of the bp in the beginning? (edited)

The TimeLeft value is set to 300 in the class default object. Every UClass has a class default object (CDO) that has default values, the default values are copied from the CDO UObject to other instances of the UClass when they are created. The TimeLeft property is not replicated, so the client still thinks the value is still 300 after you change it on the server.

c++
    FString buffPath = "Blueprint'/Game/Extinction/CoreBlueprints/Buffs/Buff_CryoCooldown.Buff_CryoCooldown'";
    UClass* buffClass = UVictoryCore::BPLoadClass(&buffPath);
    if (!buffClass) {
        Log::GetLog()->error("UClass not found - ABuff_CryoCooldown_C");
        return;
    }

    FName timeLeftName("TimeLeft", EFindName::FNAME_Find);
    UProperty* timeLeftProp = nullptr;
    for (UProperty* prop = buffClass->PropertyLinkField(); prop != nullptr; prop = prop->PropertyLinkNextField()) {
        if (prop->NameField().Compare(&timeLeftName) == 0) {
            timeLeftProp = prop;
            break;

    float timeLeft = 0;

Tbh I'm probably not grasping the whole picture. Can I somehow tell the client the new values? I update the CDO on server start/plugin reload. I just tried to buff->ForceReplicateNow(false, false); on the hooks APrimalBuff_BeginPlay and APrimalBuff_AddBuff with check for the correct classes. Both didn't work but than again I probably don't get the full picture^^

If a property isn’t replicated then there isn’t really a way to change it

substitute

If a property isn’t replicated then there isn’t really a way to change it

Does that mean that ForceReplicateNow for example only replicates "stuff" that would get replicated sooner or later anyway but there still is some "stuff" that never will be?

I believe so

1:02 AM

for example, stuff like UI is entirely client sided

1:02 AM

so you can't ever replicate that

Yeah I one time I tried to replicate stuff that won't normally replicate. You can use a plugin to make the server send out replication notices for properties that don't normally replicate, but the client will reject them.

I lied before though lol. I just looked at it again and TimeLeft does replicate. So you see the value change on the client eventually, right? It just takes a few seconds or something to change from 300?

Yes. As I said it does it "on the fly" I was just wondering where it gets the 300 seconds from when nothing serverside (as far as i can tell) has 300seconds as a property.

from the CDO

the cdo should have nothing with 300 seconds because i set both properties that have value 300 to 20 for example

I believe the time left does control the buff. But the timer clients see is DeactivatesAfterTime which is a non replicated var.

1:10 AM

DeactivatesAfterTime is what controls the buff's lifetime from the parent APrimalBuff

Dodo Enthusiast

The 300 comes from the CDO. The first code I posted prints the value from the CDO

is for optimization reasons @Dodo Enthusiast

Mollusk searches it at start up and caches it

Does this also take like 10 seconds to update the buff clientside? Which is fine and I can test myself just wondering. I mean it basically works I was just wondering about he clientside stuff.

No. That shows the correct value immediately on the client.

I also cache it already because I copied Mollusk example to my first question about this general topic

Thanks everyone for the answers. I think I need some time to make sense of it all. I don't want to claim some wrong things and waste people's time.

whare are the api docs

1

There are none.

is there any hook to check player movement (and if i "return;" i can prevent the movement)? i found

DECLARE_HOOK(USceneComponent_MoveComponentImpl, bool, USceneComponent*, FVector*, FQuat*, bool, FHitResult*, EMoveComponentFlags, bool);

but i cant stop the player movement.

You'd be using the ServerMove fns

Frigoff

You'd be using the ServerMove fns

in what structure? AShooterCharacter?

UCharacterMovementComponent

Frigoff

UCharacterMovementComponent

and how i can update the player character position? if i do

void  Hook_UCharacterMovementComponent_ServerMove_Implementation(UCharacterMovementComponent* _this, float TimeStamp, FVector_NetQuantize100 InAccel, FVector_NetQuantize100 ClientLoc, char MoveFlags, char ClientRoll, unsigned int View, UPrimitiveComponent* ClientMovementBase, FName ClientBaseBoneName, char ClientMovementMode)
    {
            return;
    }

i can move, but cant interact away from my starting position, and if i unload the plugin i got teleported to the original position.

You could try setting bCanMove or something similar on the AShooterCharacter (edited)

3:42 AM

I think that worked fairly well

So your client is basically desynced away from where the server has your character's stored position?

Frigoff

So your client is basically desynced away from where the server has your character's stored position?

yes

Instead of just returning from the function, you may have to set the location so the client updates it. I would have to reverse more to discover how that works.

3:45 AM

That ClientLoc might be relevant

Frigoff

So your client is basically desynced away from where the server has your character's stored position?

you know how i can get the server player position?

4:37 AM

bc with RelativeLocationField() / GetPosition() / GetWorldLocation are updating when i move.

Pelayori

You could try setting bCanMove or something similar on the AShooterCharacter (edited)

any examples?

4:41 AM

"bCanMove" dont exist in AShooterCharacter

Frigoff

That ClientLoc might be relevant

if i do, for example

FVector player_pos = _this->MoveStartLocationField();
if (//Check if player is in certain zone) {
    PC->SimpleTeleportTo(&player_pos, &rotation);
    return;
}

player get stucked and cant leave, because because it goes too inside xD (im using ClientLoc for calculate player location)

4:46 AM

if i use RelativeLocationField() instead of ClientLoc happens too (edited)

1. The second only works if you know for a fact that those are the exact symbol names. 2. Are you sure that the fields aren't null? You aren't checking before calling .ToString()

I suggest attaching your Visual Studio debugger to the server executable to see where exactly the crash is

5:13 AM

3. FName& is not FName*

5:13 AM

the first is a reference value, the second is a raw pointer.

5:14 AM

FName& DossierTameableDinoNameTagField() { return *GetNativePointerField<FName*> it doesn't make sense to return FName* as FName&

5:15 AM

so make sure that you are actually reading out FName and not FName*

5:16 AM

I mention this because return *GetNativePointerField<T*> returns T If the field is actually FName then FName& DossierTameableDinoNameTagField() { return *GetNativePointerField<FName*> should be fine if it is actually FName* then FName& DossierTameableDinoNameTagField() { return *GetNativePointerField<FName*> would need to be FName* DossierTameableDinoNameTagField() { return *GetNativePointerField<FName**>

The issue is that FExplorerNoteEntry isn't sized correctly in either of your definitions. UPrimalGameData::ExplorerNoteEntriesField() gives you a TArray<FExplorerNoteEntry>. TArray only works with types that are sized correctly at compile time (TArrays of pointers always work because the compiler knows the size of a pointer). We can see in IDA that the actual size of a FExplorerNoteEntry is 0xA8 bytes.

As I posted is just says "FName DossierTameableDinoNameTag;"

So you could do:

c++
struct FExplorerNoteEntry
{
    uint8 _padding[0xA8];

    int& ExplorerNoteIndexField() { return *GetNativePointerField<int*>(this, "FExplorerNoteEntry.ExplorerNoteIndex"); }

    FName& DossierTameableDinoNameTagField() { return *GetNativePointerField<FName*>(this, "FExplorerNoteEntry.DossierTameableDinoNameTag"); }
};

TheMollusk

The issue is that FExplorerNoteEntry isn't sized correctly in either of your definitions. UPrimalGameData::ExplorerNoteEntriesField() gives you a TArray<FExplorerNoteEntry>. TArray only works with types that are sized correctly at compile time (TArrays of pointers always work because the compiler knows the size of a pointer). We can see in IDA that the actual size of a FExplorerNoteEntry is 0xA8 bytes.

Why would that matter? Does UE4 store the items of a TArray as a contiguous block of memory?

5:29 AM

if so, then wild, because I'm pretty sure TArray can be resized, lol what a waste of copies

Yeah the reason his first definition works once and then fails on the second iteration is that he has sizeof(FExplorerNoteEntry) = 1, so when he accesses the "second" element of the array, he's only accessing "address of first element + 1 byte" (edited)

yea I get it

5:30 AM

it's using pointer arithmetic

5:30 AM

and falling on the wrong address

5:30 AM

it's not making me happy though

5:32 AM

yughck

5:32 AM

yeah, that's completely the issue @Dodo Enthusiast

Tbh, I again dont really know whats going on and feel like a complete beginner, but I'm starting the server now with the new definition.

The problem is that the sizeof your definition wasn't exactly the same size as the one used by the game

5:36 AM

so when you tried to read the second item in the array, it was reading the wrong address

5:37 AM

A debugger would've been a big help here

substitute

A debugger would've been a big help here

I actually used remote debugging but I seem to not be able to get informations from it. It usually crashes in some function I have never heard of with an error like "access violation". (edited)

Access Violation is the first sign

5:39 AM

it means you accessed memory that was invalid

5:41 AM

@Dodo Enthusiast when you finish creating your definition, and you have confirmed that it works

5:41 AM

you can make a PR for it.

5:42 AM

@TheMollusk I might rewrite the TArray code

5:42 AM

to instead pull the size of the structure from the UE4 reflection stuff

5:42 AM

that way it isn't a problem anymore

TheMollusk

We can see in IDA that the actual size of a FExplorerNoteEntry is 0xA8 bytes.

"We can see in IDA that the actual size of a FExplorerNoteEntry is 0xA8 bytes" how do I know that the size isnt right?

your first clue is that it was crashing LOL

5:44 AM

your second is by checking the sizeof the structure against what IDA states the size is

substitute

your second is by checking the sizeof the structure against what IDA states the size is

I think stuff like that is not as obvious to some people as you might think^^

substitute

@TheMollusk I might rewrite the TArray code

That could be a good idea. UArrayProperty has a UProperty* Inner; that you can use to get the size of the element type.

TheMollusk

So you could do:

c++
struct FExplorerNoteEntry
{
    uint8 _padding[0xA8];

    int& ExplorerNoteIndexField() { return *GetNativePointerField<int*>(this, "FExplorerNoteEntry.ExplorerNoteIndex"); }
    int& ExplorerNoteTypeField() { return *GetNativePointerField<int*>(this, "FExplorerNoteEntry.ExplorerNoteType"); }
    FString& ExplorerNoteDescriptionField() { return *GetNativePointerField<FString*>(this, "FExplorerNoteEntry.ExplorerNoteDescription"); }
    FName& DossierTameableDinoNameTagField() { return *GetNativePointerField<FName*>(this, "FExplorerNoteEntry.DossierTameableDinoNameTag"); }
};

I just tested it, it works with this definition. Thank you. (edited)

TheMollusk

That could be a good idea. UArrayProperty has a UProperty* Inner; that you can use to get the size of the element type.

yeah

5:52 AM

actually, we can take it a step further

1

5:52 AM

since the TArray is templated

5:52 AM

we can compute the size of T at construction time

5:52 AM

using the CDO

5:53 AM

that way it's only ever computed once per T

5:53 AM

pretty sure if it's a static member, it's value will get shared for every T

5:53 AM

it'll just be 0 until a TArray is constructed

5:54 AM

so the logic in the constructor could be like

5:54 AM

if (TArray<T>::Size == 0)
  TArray<T>::Size = CalculateSizeOf<T>;

(edited)

substitute

your second is by checking the sizeof the structure against what IDA states the size is

Thanks for your answers. Could you maybe give a little example on how to do that? My main issue with understanding is that the struct in IDA has like 20 fields but it seems to be ok to just define some of them, so how can I accurately compare the sizes?

anyone got a template for using cmake instead of vstudio? or any notes on what's the important parts of your template @substitute or is it a standard DLL export long as ArkApi.lib is linked?

i'm feeling so downgraded using vstudio over clion lol.

Aikar

anyone got a template for using cmake instead of vstudio? or any notes on what's the important parts of your template @substitute or is it a standard DLL export long as ArkApi.lib is linked?

it's a standard dll project but you link with ArkApi.lib if you use any API functions like SetHook etc...

3:08 PM

you can also export functions with the names Plugin_Init and Plugin_Unload

3:08 PM

Plugin_Init will be called after LoadLibrary and Plugin_Unload will be called before FreeLibrary (if they are exported)

are those more recommended than standard DLL Load/Unload?

3:12 PM

seems like every plugin ive seen just uses DLL entry point

these functions should be used when you have code that cannot execute under loader lock for example

3:13 PM

an example of this would be if you need to load another dll on your dll's load for example

whats harm in always using em

additionally Plugin_Unload can be used for freeing any threads you have created (edited)

Aikar

whats harm in always using em

no harm

k as yeah id rather not have to 2 load and 2 unload methods if not necessary lol.

3:14 PM

then everyone looking at source has to figure out which is called in what order (edited)

3:15 PM

im trying to make my first plugin finally, but man using jetbrains IDE's for so many years for every language i work in this has been a stumble with keybindings

ive accidently compiled project so many times trying to jump to symbol!

not had to use other editors tbh, my university also hands out assignments which should be completed in vscode or visual studio

yeah unis can be weird like that.

3:17 PM

i remember getting yelled at for USING Vstudio instead of command line compilers in college

i got minus 5 points on an assignment for having more than 50 characters on a line

50!? man even linux allows 70

3:18 PM

well 80 but git is 72~ for first line of commit message

3:18 PM

to allow room to display hash before it to fit 80 lol

yeah but it wasn't even my fault you have to upload just the code on their grading website and it messed up my formatting (edited)

what i learned about college courses is your instructor thinks they have the best methods and you gotta do things the same way as them or its wrong

that is exactly accurate yeah

hopefully things are better these days than 15 years ago when i went to school haha

this particular university is notorious for making the first year of Computer Science very difficult so they can get as many students to drop the course and switch to something else

3:21 PM

because most of the ppl that enroll here chose Computer Science

yeah what also sucks is CS is a flawed degree for a career too. something ive always ranted about. Things you learn in CS are great and should be learned, but when you get out and look for a job, the issue is that no one wants juniors touching code where that info is relevant lol.

3:22 PM

it's def good knowledge though to do things right early on

3:23 PM

just Software Engineering degree teaches better topics on real world topics for writing software and getting it shipped, business practices, project management, etc.

that is very true, but to be honest i've not learned anything in university pretty much all of my knowledge can be accredited to the very cool developer of this project (Michidu) he very generously taught me pretty much everything about c++ lol

yeah that's how I ultimately learned over the years, I got started in high school and actually didnt learn anything in HS or college programming classes. I've been at it over 20 years now lol.

3:25 PM

been 15 years since I touched C++ though so got to catch up on new things

you have have been gathering experience for more time than i've been alive

yep lol. I come from minecraft community where def huge influx in young developers ive helped teach things over the years

very nice to have you in our community

Aikar

I disagree, computer science as a degree is fine. It’s all about computer science

3:54 PM

If someone wants to go into software engineering, a software engineering degree is better.

except what most people get a CS Degree for is to do software engineering, unless your definition of software engineering is different than mine lol.

4:12 PM

if you're not building software, im struggling to think what is CS gonna do for you outside of academics?

does anyone know of an example plugin using cmake

9:01 PM

used cmake-converter on subs template but def not working yet

Hello, do you know if the api works on mtxserv servers ?

Aikar

if you're not building software, im struggling to think what is CS gonna do for you outside of academics?

Yes, a CS degree is for academics

9:15 PM

You want a CE degree for engineering

9:15 PM

I went the CS route because I want to eventually get my PhD

Aikar

does anyone know of an example plugin using cmake

Why not use MSVC with CLion?

9:17 PM

https://www.jetbrains.com/help/clion/quick-tutorial-on-configuring-clion-on-windows.html

Tutorial: Configure CLion on Windows | CLion

9:17 PM

Pretty sure it’s supported

9:18 PM

Only thing you might need to move over is the additional includes and library directories

maybe this will work, i had selected VStudio toolchain but it still kept complaining about cmake

i think issue was ultimately with cmake-converter, i made new project and just copied the main cmake configs in to it and the files and got it to compile (edited)

9:28 PM

this guide is ultimately what i had going, cmake still uses the vs toolchain to compile

Ainz Ooal Gown

Hello, do you know if the api works on mtxserv servers ?

For information yes it works on mtxserv you just have to install the API and reboot the server to finish the installation.

getting stuck :/ https://gist.github.com/aikar/47cd115b196b3361153dfea9e66f3e56 plugin compiles but gives 126. searching discord mentions dependency issues, but what dependency? clearly ARK API is loaded lol. everyone elses plugin loads so clearly shouldnt be missing any system deps.

tried commenting out near all the code to make sure init isnt having an error

hmm release mode worked, is it just something wrong with debug builds

void Hook_NotifyItemAdded(AShooterCharacter* _this, UPrimalItem* item, bool bEquipItem) {
        NotifyItemAdded_original(_this, item, bEquipItem);
        if (!item) {
            return;
        }

        try {
            FString name = item->NameField().ToString();
            if (!name.Contains("PrimalItem_AwesomeSpyGlass_C")) {
                LOG->info("No Match" + name.ToString());
                return;
            }

            auto controller = ArkApi::GetApiUtils().FindControllerFromCharacter(_this);
            if (!controller) {
                LOG->info("No Controller" + name.ToString());
                return;
            }
            //if (!_this->HasBuff())
            controller->ServerRequestInventoryUseItem(_this->MyInventoryComponentField(), item->ItemIDField());
            LOG->info("Used Spyglass: " + name.ToString());
        } catch (const std::runtime_error &e){
            LOG->error("RuntimeError: " + std::string(e.what()));
        } catch (const std::exception &e) {
            LOG->error("Exception: " + std::string(e.what()));
        }
}

so is there a different way to get controller than this? hooks firing correctly, just cant get controller w/o crash, and is there something I can do to catch the error properly and not crash the whole server? SET_HOOK("AShooterCharacter.NotifyItemAdded", NotifyItemAdded); For the Hook

5:22 AM

once i get basics working ill add in the buff detection to not use it if its already active (ie picked up a duplicate spyglass)

You pretty much need to nullptr check all pointers before using them.

but isnt this saying its crashing inside of the FindControllerFromCharacter, which only param there is _this

6:11 AM

and how would _this be null

6:14 AM

or was it cause i need: auto* controller = ArkApi::GetApiUtils().FindControllerFromCharacter(_this); to avoid auto deref?

6:15 AM

though im literally in game so why would that ptr be null, how do i get the controller for the char receiving item (edited)

AShooterCharacter has a ControllerField in it

7:01 AM

Technically it's on the APawn (edited)

auto* controller = static_cast<AShooterPlayerController*>(_this->ControllerField()); ?

7:03 AM

tried a LastValidController but that was null

You don't need the * on auto but ye

7:03 AM

Give that a try

really wish this dang ASM rcon had up arrow for previous commands to help with unload/load repeating

7:06 AM

sweet that seemed to work, now to the next crash lol

Aight

7:07 AM

Hmm

guessing controller->ServerRequestInventoryUseItem(controller->GetPlayerInventory(), item->ItemIDField()); is bettter to do

7:08 AM

ultimately i want on obtaining a spyglass, use it

7:08 AM

then ill do login hook to auto use it then too

I don't know why it would crash on FindFunction

7:09 AM

Only thing I can think of is that somehow the controller passed is in valid

7:09 AM

Can you print the ObjectFlags of the controller

line that crashed was: controller->ServerRequestInventoryUseItem(_this->MyInventoryComponentField(), item->ItemIDField());

7:10 AM

im about to try using the PlayerInventory instead

That just does controller->character->InventoryComponent

7:10 AM

Should be the same

think there needs to be a delay before using on notify added? but should really be in inventory at that point shouldnt it

Aikar

really wish this dang ASM rcon had up arrow for previous commands to help with unload/load repeating

if you put a new DLL in your plugin folder named like this "YourPluginName.dll.arkapi" the api will auto load it for you.

1:59 PM

You no longer need to unload/load it manually via commands.

2:00 PM

Also when testing you should include the plugins PDB file so you can get full debugging output.

2:02 PM

I never use "auto" I always strictly type my vars. I doubt there is anything wrong with using "auto" I just like to have them defined in the code from the start.

2:04 PM

You can also try moving NotifyItemAdded_original(_this, item, bEquipItem); to the bottom of your hook incase those pointers are destroyed or invalid after the original code runs.

Aikar

sweet that seemed to work, now to the next crash lol

Did FindFunction return null?

Lethal

I never use "auto" I always strictly type my vars. I doubt there is anything wrong with using "auto" I just like to have them defined in the code from the start.

Hi, there are cases where you have to use auto in C++

6:50 PM

[[nodiscard]] constexpr auto operator*() const { return *immutable_ptr; } in my container over raw pointers

6:51 PM

if you use T (we know T as T, not T*) with *immutable_ptr and it points to a function T, then you will fail to compile

6:51 PM

because *T on T* when T* is a function produces T* and not T

CLang tidy yells at me to use auto to keep it cleaner and not double write the type def for the static cast lol

7:01 PM

@substitute havent figured that one out yet, had to sleep and now work.

7:01 PM

gonna try lethals suggestion see if it is a pointerbeing free'd issue to move the original call down (edited)

I also suggest using FindFunctionChecked

but the this_ reference is fine, as well as item, so i suspect its not that

which will throw an assert crash

7:02 PM

if it can't find the function

but im not calling that method, its the ->ServerRequestInventoryUseItem doing it self

7:02 PM

the crash is inside of that method

what are you passing to that method?

7:03 PM

are you sure MyInventoryComponentField isn't null?

im not yet, havent gotten to debugging that, but how would a players inventory be null if online lol

7:06 PM

hence i was questioning am i using wrong inventory

7:06 PM

cant remember if i tried the PlayerInventory one or not before bed, but person above said it should ultimately be same call

I suspect you’re being trolled by UE4 garbage collector but that’s my final stretch on what I can think of

8:28 PM

You’d have to print the object flags

8:28 PM

Nullptr checks aren’t enough

Issues we had were on an old version of the API were not all PDB symbols were exported. API had a default fields, and devs had to include other symbols in a PdbInfo.json file too. Our issue ended up being APawn not being exported hence the function address being garbage It is no longer necessary since we forced all symbols to be exported since 3.51 version (edited)

I even found a blueprint using hooks. But I couldn't find the item name. Which method should I use?

well tried moving the callback to after andu sing getPlayerInventory, still cant get an inventory comp for the player, im getting no comp log msg: https://gist.github.com/aikar/344aac731a90759c370f5fdd744c14c9 I was looking back at what natsu provided here: https://discord.com/channels/513432877904691202/513432877904691205/1083445372883587122 and was trying

UFunction *pFunction = _this->FindFunctionChecked(FName("ToggleUILock", EFindName::FNAME_Find));
            if (pFunction) {
                LOG->info("ProcessEvent");
                _this->ProcessEvent(pFunction, {});
                return TRUE;
            }

But that doesnt find the function nor does item->FindFunctionChecked. function approach feels like could be more reliable, anyone got tips on what i could try to fix for function method?

no wonder that doesnt work

@Natsu how did you load the mod into dev kit to see that? can it be done for AwesomeSpyglass, you did SuperSpyglass which isnt same thing. I tried loading uasset file in dev kit but it didnt like it. compiled a ue4 compress app to de compress the .z asset.

you can't view that stuff in the devkit when the mod is cooked

3:31 AM

at that point, it's essentially compiled

3:31 AM

you can however dump the fields and functions for a blueprint using UE4 reflection

ah im guessing natsu got it loaded cause that mod is open source and prob released the files

including the parameters for a function

but thats not the mod im using

3:35 AM

kinda out of ideas to try until yall can give me some tips at this point

i just cant find a function thatll give me the players inventory component

3:35 AM

UPrimalInventoryComponent* comp = _this->MyInventoryComponentField();
            if (comp) {
                auto itemId = item->ItemIDField();
                controller->ServerRequestInventoryUseItem(comp, itemId);

feels like it should work

if you want when the character spawns

3:37 AM

this may be a good hook AShooterCharacter::BeginPlay

im not on that one yet, im just doing pick up item first then ill move on to spawn

3:38 AM

or well login

don't you want on spawn

itemadded feels like best hook to handle player receiving their inventory after death

3:38 AM

they wont have spyglass yet

since you have to activate the spyglass

3:38 AM

so you don't always have the spyglass?

after death, when the keep inventory mod returns their inventory

3:39 AM

i was thinking logically, on spyglass receive, if buff not active, use spyglass (finding buff is next step)

Can you send me the mods

  }

im not getting to that line

4:00 AM

i cant get ahold of the inventory comp

Item->Use(Item, v4); is probably what you want

Aikar

i cant get ahold of the inventory comp

you might not even need it

ah interesting

since you have the direct item reference

any idea why i cant get it during this event though?

well for starters you're using AShooterPlayerController::ServerRequestInventoryUseItem (edited)

4:02 AM

I'm looking at UPrimalInventoryComponent::ServerUseInventoryItem

im still talking about before that method, in the NotifyItemAdded, the AShooterCharacter->MyInventoryComponentField() is returning null

4:03 AM

Yes, but that just calls UPrimalInventoryComponent::ServerUseInventoryItem

4:03 AM

which eventually just calls Item->Use(Item, v4);

4:03 AM

at least that's what I'm expecting to happen under the hood in the BP stuff (edited)

4:10 AM

i have UPrimalItem not Item but it worked! item->Use(false);

4:10 AM

I'll let you know if it works

4:10 AM

oh

4:10 AM

just doing item->use worked for you?

yes

nice

is there a command to dump all buffs i have

you could write one

as i need to handle duplicate spyglasses

4:11 AM

so it doesnt toggle it back off

The Character should always have a valid pointer to it's own inventory.

man my old coworker would scream at that code you pasted. he was such a strong believer in "Guard Clause Dont Nest"

That's IDA code pretty sure

It's IDA Code

Maybe cleaned up a little

so how come i keep getting null

Frigoff

The Character should always have a valid pointer to it's own inventory.

not if the character doesn't have an inventory

or is my if (!comp) wrong

but the inventory should have a character

Are you firing the original

and it needs to be if != nullptr

Aikar

and it needs to be if != nullptr

if(!x) is fine

i fired it AFTER yes, per suggestions

you could have tried this AShooterPlayerController* playerController = playerInventory->GetOwnerController();

Let me take a look

Frigoff

Let me take a look

I'm thinking the definition isn't correct

4:18 AM

in the API any more

auto controller = static_cast<AShooterPlayerController*>(_this->ControllerField()); was working

4:18 AM

UPrimalInventoryComponent* comp = _this->MyInventoryComponentField(); this is what failed condition check

because I got the crash too and it's due to a fucked up pointer value (edited)

4:19 AM

specifically on _this->GetOwnerController()

4:19 AM

btw @Aikar make sure to filter out engrams too

4:19 AM

as those count as items

i guess question - this method lives on APrimalCharacter but I added it to AShooterCharacter to only hook for Shooter chars, could that be causing anything? but so far everything else about it worked

4:20 AM

yeah i asdded logic since then for that

4:20 AM

as i saw it in ArkShop code

4:20 AM

that's the error

Nah if you hook the AShooterCharacter one you should be fine

even GetOwnerController is throwing

BOOL trySpyglass(AShooterCharacter *_this, UPrimalItem *item) {
        FString name = item->NameField().ToString();
        if (!name.Contains("PrimalItem_AwesomeSpyGlass_C")) {
            return FALSE;
        }
        try {
            auto controller = static_cast<AShooterPlayerController*>(_this->ControllerField());
            if (!controller) {
                return FALSE;
            }
            TArray<APrimalBuff*> buffs;
            _this->GetAllBuffs(&buffs);

            LOG->info("Used Spyglass: " + name.ToString());
            item->Use(false);
            return TRUE;
        } catch (const std::runtime_error &e){
            LOG->error("RuntimeError: " + std::string(e.what()));
        } catch (const std::exception &e) {
            LOG->error("Exception: " + std::string(e.what()));
        }
        return FALSE;
    }

    void Hook_NotifyItemAdded(AShooterCharacter* _this, UPrimalItem* item, bool bEquipItem) {
        if (_this && item && item->ClassField() && !item->bIsEngram()()) {
            trySpyglass(_this, item);
        }
        NotifyItemAdded_original(_this, item, bEquipItem);
    }

so something in the game is definitely amiss

is what I have working now, trying to add buff check now

4:20 AM

but uh its been 15 years since C++ and i dont remember how to foreach LOL

Sure

4:21 AM

for(const auto& element : container)

i dont know the name of the buff yet to just check for specific buff

you can dump the buff names

yeah thats what im trying to do

I would compare with the FName

4:21 AM

That will give you the fastest easiest solution I've found

4:22 AM

buff->Name.ComparisionIndex

4:22 AM

@substitute Does the API have the object flags check

he's going to need to modify the api definition for APrimalBuff

4:22 AM

it doesn't contain padding

4:23 AM

and the return value of BuffsField is TArray<APrimalBuff>

4:23 AM

I might just write the modified code to compute the size at construction time so it's not an issue for anyone

_this->GetAllBuffs(&buffs);
            for(const auto& buff : buffs) {
                auto buffName = buff->NameField().ToString();
                if (buffName.Contains("Spyglass")) {
                    LOG->info("Buff: " + buffName.ToString());
                    return TRUE;
                }
            }

?

Aikar

_this->GetAllBuffs(&buffs);
            for(const auto& buff : buffs) {
                auto buffName = buff->NameField().ToString();
                if (buffName.Contains("Spyglass")) {
                    LOG->info("Buff: " + buffName.ToString());
                    return TRUE;
                }
            }

?

that will fail

4:24 AM

because TArray uses pointer arithmetic for getting items

4:24 AM

and sizeof(APrimalBuff) is 0 in the API

4:25 AM

you'll have to add padding to APrimalBuff until I write code to TArray to avoid this issue

Should be APrimalBuff* sizeof that should be 8

actually, you're right

4:25 AM

it is an array of pointers

GetAllBuffs returns TArray<APrimalBuff*>

4:25 AM

yes

and not an array of values

4:25 AM

so it'll be fine since sizeo(T*) is always sizeof(void*) (edited)

Aikar

_this->GetAllBuffs(&buffs);
            for(const auto& buff : buffs) {
                auto buffName = buff->NameField().ToString();
                if (buffName.Contains("Spyglass")) {
                    LOG->info("Buff: " + buffName.ToString());
                    return TRUE;
                }
            }

?

Looks fine to me

4:26 AM

Though in the future you should move from string comparing

so ArkApi needs an update? would the Hasbuff method work fine if i get the proper BP path for the UVictoryCore stuff?

4:26 AM

yeah im trying to just dump for now

yeah

i dont know the bp path at all currently so just want to dump

Aikar

so ArkApi needs an update? would the Hasbuff method work fine if i get the proper BP path for the UVictoryCore stuff?

I've never tested that

Aikar

so ArkApi needs an update? would the Hasbuff method work fine if i get the proper BP path for the UVictoryCore stuff?

it should work fine (the api)

4:26 AM

since TArray in this instance is for a pointer type

oh ight you was meaning API looks wrong for the inventory stuff right

4:27 AM

and not buffs

Aikar

oh ight you was meaning API looks wrong for the inventory stuff right

it could also just be an "ark thing"

4:27 AM

where there isn't really a fix

4:27 AM

there's a lot of bad code in Ark

and why the fuck does the item name field append an incrementing number every time

Aikar

and why the fuck does the item name field append an incrementing number every time

it's a unique instance of that class

4:28 AM

so the name has to be unique

4:28 AM

you can just trim that off

That's because of GlobalNames and GlobalObjects

yeah i did the contains to get around it

@Frigoff we should reverse engineer broken things and write patches that fix the broken things

Sure.

careful, youll end up like what we did for minecraft

First thing on the list is GetDescriptiveName memory leak

what's the leak?

https://github.com/PaperMC/Paper/tree/master/patches/server

Paper/patches/server at master · PaperMC/Paper

High performance Spigot fork that aims to fix gameplay and mechanics inconsistencies - Paper/patches/server at master · PaperMC/Paper

Last time I used that function a lot it would jump memory a lot

nearly 1000 patches lol

Aikar

https://github.com/PaperMC/Paper/tree/master/patches/server

I have plans to implement s3 transfers for everyone

4:29 AM

it's possible to use s3 as your transfers backend already

4:29 AM

without any plugins with a command line arg

4:29 AM

but it doesn't enable the anti-dupe timer

And I'm fairly certain it's because their way of appending the names

4:29 AM

Because descriptive name

4:29 AM

Returns Playername - Lvl

is any decompiler good enough to create a compilable server to actually patch server code and rebuild?

and I think their really old logic causes a memory server

Aikar

is any decompiler good enough to create a compilable server to actually patch server code and rebuild?

IDA is your best bet but I personally like Binary Ninja

that was one good thing about java is we could do this patchin then compile

And most cases since the PDB doesn't get the types right with templated types it takes some x64dbg knowledge to get it

i have ghidra or w/e its called and looking at some stuff i just havent figured out how to just make it dump everything as this app sucks for navigating

If you're looking to just go through the game classes I highly recommend dumping an SDK

4:31 AM

And if you're looking for a good dump, IDA is your best bet

4:32 AM

sadly because IDA sucks

something tells me that your buff that you want

4:32 AM

is AwesomeSpyGlass_Buff

yeah well im not looking to pay for that and try not to pirate things anymore

4:32 AM

lol

yeah thats the file i was trying to load in devkit lol

Aikar

is any decompiler good enough to create a compilable server to actually patch server code and rebuild?

not exactly

Aikar

yeah well im not looking to pay for that and try not to pirate things anymore

Ghidra is probably your best unless you want to try out Binary Ninja

but you could overwrite the existing implementation for something

I like Binary Ninja because it's multithreaded analyzing

and never call the original

4:33 AM

you can even reclaim the memory the original used by marked the memory as writable and freeing it

4:33 AM

if you're feeling bold

Does detours fix the stack

4:33 AM

If you don't call the original

im trying to leep it simple for now lol

Frigoff

Does detours fix the stack

that would only be an issue for functions that are LTO

4:33 AM

everything else is __fastcall

Can you expand LTO

link time optimization

i see

and whole program optimization

4:33 AM

that's what produces those garbage non-standard calling conventions

Ah

they're not garbage for optimization

4:34 AM

but they're garbage for hooking because you can't just hook them

4:34 AM

you have to write assembly code to translate the stack from that to something like __fastcall

4:34 AM

and then back into whatever it expects for clean up

yikes

like if the expectation is eax,ebx,ecx are used

Ye I got you

but the convention expects everything on the stack

4:35 AM

you'll know you found one of these functions when you see __usercall in IDA

4:35 AM

if you see __fastcall then just use cdecl in x64

4:35 AM

since that is __fastcall

Ye __fastcall is babe (edited)

Aikar

im trying to leep it simple for now lol

Did you get it working?

it's just the default for x64

4:36 AM

x32 is where calling conventions actually matter

so far my buff code isnt printing so moving my log to just dump them all, unless this buffs array isnt looping at all

the ark show is an anime guys

4:36 AM

the skin proves it

Do you have any buffs on the character?

yeah

You might not get any until the next game tick when you've equipped something

ive got the arkshop ui one

4:37 AM

though the spyglass doesnt seem to put an actual buff icon in bottom right

4:37 AM

so is it gonna show up

You can disable that icon from showing up

ah

In the blueprint

TArray<APrimalBuff*> buffs;
            _this->GetAllBuffs(&buffs);
            for(const auto& buff : buffs) {
                auto buffName = buff->NameField().ToString();
                LOG->info("Buff: " + buffName.ToString());
                if (buffName.Contains("Awesome_SpyGlass")) {
                    return TRUE;
                }
            }

didnt print anything so i dont think its finding the buffs correctly, but didnt crash at least.

@Frigoff HDR moment

4:39 AM

AH HELL NAH

im dropping 2 spyglasses, first turns it on, then 2nd is turning it off

4:39 AM

oh im on 4k hdr too

Maybe try printing buffs size?

I'm thinking the iterator might be the issue

4:41 AM

the game uses indexes

4:41 AM

not iterators

I can't remember the apis implementation of iterators

is it ->Num for size?

Yes

4:44 AM

Though since your TArray isnt a pointer it should be (edited)

4:44 AM

.Num

Num is showing 0 for me

yeah

4:47 AM

i expect it to least be showing the ark shop ui, but expectation is after first id see the spyglass buff and can return early

There's a different way, gonna test rq

there is GetBuffs too

and GetAllBuffs

4:48 AM

which is probably more useful since it ensures no filters

i was using GetAllBuffs

I was using ->Buffs() (edited)

then ->GetBuffs is the next try lol

4:48 AM

all these sim named things is pretty confusin

4:49 AM

that ones 0 too

@Frigoff

5:02 AM

I think I know the problem

5:02 AM

NotifyItemAdded is probably for sending a notification to the player

5:02 AM

so some things may not have their server sided data attached to them

pretty sure it is yeah

5:02 AM

1 tick delay should solve?

UPrimalCharacterStatusComponent::CharacterUpdatedInventory

5:03 AM

that's probably better

hmm would that handle login too

and with this you can iterate the inventory and toggle the buff (and break your iterator)

feels slower to do that than on notify of a new item though where can do simple check and ignore rest

5:04 AM

and only scan inv for the login scenario

5:04 AM

cant i just timer 0 delay to run next tick

You won't ever have the server sided data

5:04 AM

if it isn't attached to the reference you got

Can you explain to me what you’re trying to do

5:04 AM

Maybe I know a good starting point

does it not just keep a single char object

He wants to toggle an item when it is in his inventory

Aikar

does it not just keep a single char object

as we can see in this case, no

5:05 AM

since we don't have any of our buffs

5:05 AM

and that code should work given that other people have used buffs before without issue

I’ve personally used GetAllBuffs (edited)

and it also crashes when trying to get the owning controller

yeah and im now trying to use the buffs to find out when the item is ALREADY on and ignore it to avoid toggling off

5:07 AM

you could also try these

5:08 AM

@Frigoff IDA moment

5:08 AM

I mean

5:08 AM

At least it

5:08 AM

Saved you

5:08 AM

When I dump the game

it didn't save shit

I always copy the db

5:08 AM

Because yeah

5:09 AM

Ida can be trash

https://medal.tv/games/ark/clips/ZNNf67VM9AgP_/d1337wz1JRuP?invite=cr-MSxtMmUsMTY2OTIzMDE4LA this will show it

5:10 AM

notice gps toggled off when picked up 2nd one

5:10 AM

trying to avoid that and my understanding is theres a buff active while its on so tryin to look for it and don't re-use if it is on.

5:11 AM

sure perfect world people only have 1 spyglass lol

There is also UPrimalItem::AddToInventory

5:12 AM

which absolutely should have everything

@substitute does the inventory have a begin play

5:12 AM

Or tick

Everything has a beginplay and tick

Well then that’s how I’d do it

would this method also be fired upon login as the char is being created lol

5:12 AM

but i can try it

5:12 AM

but does the uprimalitem have a char reference

5:14 AM

hey could i just always pass equipitem true for this?

5:14 AM

to that method

5:14 AM

(UPrimalInventoryComponent* toInventory, bool bEquipItem, bool AddToSlotItems, FItemNetID* InventoryInsertAfterItemID, bool ShowHUDNotification, bool bDontRecalcSpoilingTime, bool bIgnoreAbsoluteMaxInventory) { NativeCall<void, UPrimalInventoryComponent, bool, bool, FItemNetID, bool, bool, bool>(this, "UPrimalItem.AddToInventory", toInventory, bEquipItem, AddToSlotItems, InventoryInsertAfterItemID, ShowHUDNotification, bDontRecalcSpoilingTime, bIgnoreAbsoluteMaxInventory); }

I believe so.

Aikar

but does the uprimalitem have a char reference

it has a reference for the inventory

5:14 AM

which should have a character attached to it

I think that's how equipping an item from a vault works ^^

you'll have to verify that the inventory IS a player character though

that should be easy enough

        static void onNotifyItemAdded(UPrimalInventoryComponent* _this, UPrimalItem* anItem, bool bEquipItem)
        {
            NotifyItemAdded.original(_this, anItem, bEquipItem);
            if (!_this || !anItem)
                return;
            
            AActor* owner = _this->GetOwner();
            if (!owner || !owner->IsA(AShooterCharacter::StaticClass()))
                return;

            AShooterCharacter* playerCharacter = static_cast<AShooterCharacter*>(owner);

            Log::GetLog()->error("has buff count {}\n", playerCharacter->BuffsField().Num());
            anItem->Use(true);
        }

5:15 AM

I'll give this a shot

5:17 AM

this was not it chief

Yeah might be worth to try

5:19 AM

UPrimalInventoryComponent::TickComponent

lol

5:19 AM

I forgot to update teh reference

LOL

if that doesn't work I'll make it work with

5:21 AM

@Frigoff

5:22 AM

UE4 is such a piece of shit man

LOL

5:22 AM

Trust me

5:22 AM

the other engines I've studied

5:22 AM

This is top of the line

5:23 AM

hey

5:23 AM

@Aikar

5:23 AM

UPrimalInventoryComponent.NotifyItemAdded

5:23 AM

that's what you want

5:23 AM

that executes on the server w/ everything

5:23 AM

        static void onNotifyItemAdded(UPrimalInventoryComponent* _this, UPrimalItem* anItem, bool bEquipItem)
        {
            NotifyItemAdded.original(_this, anItem, bEquipItem);
            if (!_this || !anItem)
                return;
            
            AActor* owner = _this->GetOwner();
            if (!owner || !owner->IsA(AShooterCharacter::StaticClass()))
                return;

            AShooterCharacter* playerCharacter = static_cast<AShooterCharacter*>(owner);

            Log::GetLog()->error("has buff count {}\n", playerCharacter->BuffsField().Num());
            anItem->Use(true);
        }

k

5:25 AM

though, im curious to try the equipitem bool then i dont even need to check buffs

5:26 AM

void Hook_NotifyItemAdded(AShooterCharacter* _this, UPrimalItem* item, bool bEquipItem) {
        if (_this && item && item->ClassField() && !item->bIsEngram()()) {
            FString name = item->NameField().ToString();
            if (name.Contains("PrimalItem_AwesomeSpyGlass_C")) {
                NotifyItemAdded_original(_this, item, true);
                return;
            }
            //trySpyglass(_this, item);
        }
        NotifyItemAdded_original(_this, item, bEquipItem);
    }

gonna try this

yeah that didnt work at all

5:27 AM

has to be a use not equip, so going to yourhook

5:33 AM

woot thats working just gotta fix my has buff check:

5:33 AM

if (buffName.Contains("AwesomeSpyGlass")) { had a `\` in there mistakenly (edited)

you should check the full blueprint path of the buff

5:34 AM

imagine if there's a server with another spyglass named buff (edited)

5:34 AM

FString spyGlassBuffBlueprint = "Blueprint'/Game/Mods/AwesomeSpyglass/AwesomeSpyGlass_Buff.AwesomeSpyGlass_Buff'";

literally named AwesomeSpyGlass lol?

explicit safety over implied safety

but yeah im good with full bp

5:36 AM

whats method to compare BP for? i dont see anything super obvious in completion

You could either load the UClass at the BP and check if the buff/item are the same UClass

5:37 AM

or you could do a string comparison

lol yeah i rather keep it simple, the odds of someone trying to make a mod with exact same buff name and using my plugin

5:38 AM

these try catches are useless yeah?

5:40 AM

and ill use startswith for performance opt

5:41 AM

so current ver:

void trySpyglass(AShooterCharacter *_this, UPrimalItem *item) {
        static auto BuffName = "AwesomeSpyGlass_Buff";
        static auto ItemName = "PrimalItem_AwesomeSpyGlass_C";
        FString name = item->NameField().ToString();
        if (!name.StartsWith(ItemName)) {
            return;
        }

        TArray<APrimalBuff*> buffs;
        _this->GetBuffs(&buffs);
        for (int i = 0; i < buffs.Num(); i++) {
            APrimalBuff* buff = buffs[i];
            auto buffName = buff->NameField().ToString();
            if (buffName.StartsWith(BuffName)) {
                return;
            }
        }

        item->Use(false);
    }

    void Hook_NotifyItemAdded(UPrimalInventoryComponent* _this, UPrimalItem* anItem, bool bEquipItem) {
        NotifyItemAdded_original(_this, anItem, bEquipItem);
        if (!_this || !anItem || anItem->bIsEngram()())
            return;

        AActor* owner = _this->GetOwner();
        if (!owner || !owner->IsA(AShooterCharacter::StaticClass()))
            return;

        auto playerCharacter = static_cast<AShooterCharacter*>(owner);
        trySpyglass(playerCharacter, anItem);
    }

This should work as well

5:44 AM

        static void onNotifyItemAdded(UPrimalInventoryComponent* _this, UPrimalItem* anItem, bool bEquipItem)
        {
            static FString spyGlassBuffBlueprint = "Blueprint'/Game/Mods/AwesomeSpyglass/AwesomeSpyGlass_Buff.AwesomeSpyGlass_Buff'";
            static FString spyGlassBlueprint = "Blueprint'/Game/Mods/AwesomeSpyglass/PrimalItem_AwesomeSpyGlass.PrimalItem_AwesomeSpyGlass'";

            static UClass* spyGlassBuffClass = UVictoryCore::BPLoadClass(&spyGlassBuffBlueprint);
            static UClass* spyGlassClass = UVictoryCore::BPLoadClass(&spyGlassBlueprint);

            NotifyItemAdded.original(_this, anItem, bEquipItem);
            if (!_this || !anItem || !anItem->IsA(spyGlassClass))
                return;
            
            AActor* owner = _this->GetOwner();
            if (!owner || !owner->IsA(AShooterCharacter::StaticClass()))
                return;

            AShooterCharacter* playerCharacter = static_cast<AShooterCharacter*>(owner);
            if (playerCharacter->HasBuff(spyGlassBuffClass, true))
                return;
            anItem->Use(true);
        }

and what was the method for on login

(in C++, a static local variable is initialized once and never again, so there is no performance concern here)

yeah i know thats why i did it in my code here too for the initial strings to compare

5:45 AM

as wasnt sure if it would smart intern that or not

5:46 AM

cant remember shit for what cpp does for optimizations

5:46 AM

and plus so much has changed since i was messing with it too

5:46 AM

i didn't even know what interning was then!

They do a lot so much infact it's hard to know all of them

I just tested it

5:47 AM

the code I posted works

5:48 AM

and should be the most optimal solution

5:48 AM

HasBuff uses IsA for example

nice, i was breaking it out into a method to also use during login (though guess dropping that boolean was a bad idea there on return to know when to abort early)

the logic will be a little different on login

5:48 AM

you'll want to scan the user inventory for the item

5:48 AM

and then enable the buff

5:48 AM

I don't imagine the buff is persistent?

yeah i was gonna do foreach item, if (trySpyglass(this, item)) { return; }

5:49 AM

id imagine not since its not active during login

5:49 AM

gotta manual for login or death

you can use

5:49 AM

it's what I use for my boss unlocking thing

and thats not for new player creation lol?

it's for both

i guess this is wildcard, bad names expected

onStartNewShooterPlayer(AShooterGameMode* _this, APlayerController* newPlayer, bool forceCreateNewPlayerData, bool isFromLogin, const FPrimalPlayerCharacterConfigStruct& characterConfig, UPrimalPlayerData* playerData)

that sounds like create new player to me

you want isFromLogin = true

oh its a bool

What about transfering

5:50 AM

Or downloading

this fires on transfer too

5:50 AM

UPrimalPlayerData has the transferred data

Nice

and i do want to release this as a free plugin, as you see this is a super popular mod, im sure many would want this

if you don't I will

its drove me nuts it wasnt an option by default

since I wrote the same code too

lol hey if you wanna go ahead and make a proper build please do

5:51 AM

credit isnt important you def did the work here helping me learn

there's one warning I have for you when working with me

5:51 AM

and that's that I am a very hardline open source supporter

And he smells

5:52 AM

So stay far away

so anything I write I outside of work goes OSS

ive uh gone a bit inactive past few years, world state put me in a just relax mode

5:52 AM

but yeah i am super OSS

trying to get stuff at work OSS'd too

hey you wanna see something cool?

was a good year

5:53 AM

never got past proof of concept phase

5:53 AM

but integrating REST into the server

5:53 AM

the webpage sends a post command to the game server, which adds the selected item

6:00 AM

static auto onStartNewShooterPlayer(AShooterGameMode* _this, APlayerController* newPlayer, bool forceCreateNewPlayerData, bool isFromLogin, const FPrimalPlayerCharacterConfigStruct& characterConfig, UPrimalPlayerData* playerData)
        {
            AShooterPlayerController* playerController = static_cast<AShooterPlayerController*>(newPlayer);
            StartNewShooterPlayer.original(_this, newPlayer, forceCreateNewPlayerData, isFromLogin, characterConfig, playerData);

            if (!playerController)
                return;
            AShooterCharacter* playerPawn = playerController->LastControlledPlayerCharacterField().Get();
            if (!playerPawn)
                return;

            static FString spyGlassBlueprint = "Blueprint'/Game/Mods/AwesomeSpyglass/PrimalItem_AwesomeSpyGlass.PrimalItem_AwesomeSpyGlass'";

            static UClass* spyGlassClass = UVictoryCore::BPLoadClass(&spyGlassBlueprint);

            for (auto&& item : playerPawn->MyInventoryComponentField()->InventoryItemsField())
            {
                if (!item->IsA(spyGlassClass))
                    continue;
                item->Use(true);
                return;
            }
        }

6:00 AM

something like that is probably good enough tbh

6:01 AM

StartNewShooterPlayer.original is my own container over functions that can be hooked, if you end up using this you'll have to change it to the function the API macro generates instead

yeah i know, i modded yours from that earlier

static inline moar::function_ptr<void(AShooterGameMode*, APlayerController*, bool, bool, const FPrimalPlayerCharacterConfigStruct&, UPrimalPlayerData*)> StartNewShooterPlayer;

6:01 AM

yeah i got the gist of what its doing, just def trying to keep it simple for now lol.

6:07 AM

but yeah id say since you got it all working and its now all your code id say release it so its under your credit. ill just compile it for my own needs for now so i can get it on my server then remove code from my personal plugin once standalone is ready

6:08 AM

but def appreciate help its def helped me learn

6:08 AM

just all these damn data not avail states is gonna be a pain

6:08 AM

or is most hooks not that unlucky?

6:09 AM

also i got CLion working good with this CMakeLists https://gist.github.com/aikar/76439555cbc9e6448bc9e0ebd3c43ca8

CMakeLists.txt

GitHub Gist: instantly share code, notes, and snippets.

6:09 AM

so happy to be in jetbrains IDE

You'll probably have to add a delay on the onStartNewShooterPlayer

I pay for jetbrains all access toolbox so i get entire suite of tools

            for (auto&& item : playerPawn->MyInventoryComponentField()->InventoryItemsField())
            {
                Log::GetLog()->error("item {}\n", item->NameField().ToString().ToString());
                if (!item->IsA(spyGlassClass))
                    continue;

                API::Timer::Get().DelayExecute([item]()
                    {
                        item->Use(true);

                    }, 1);
                return;
            }

6:11 AM

I'll see how that goes

lol i had just compiled and was about to update test server

6:12 AM

stupid RDP Shared drive is so slow to copy

6:13 AM

i will bitch about windows every day of using windows again

6:13 AM

i miss my linux life

actually thinking about it, just adding the buff directly is probably best when the user logs in, assuming they have the spyglass

6:14 AM

assuming that just adding the buff works

id ask if the mod does anything BEFORe the buff is the question

6:15 AM

next task after this should hopefully be A LOT more simpler, simply setting damn exp caps on exp earned per kill, so people doing bosses cant go getting 100 mil exp in 10 mins on a 2x Server

6:16 AM

ooo since ark doesnt give us commands to take away exp, a plugin def should be able to do it

6:17 AM

other day had to roll my damn char back as when i tested your ark auto bosses first build it corrupted my char and lost all my XP, and when i tried to give EXACTLY what i had back, damn XP multiplier kicked in and gave me way too much lol

6:21 AM

speaking of that plugin didnt you say it requires an ArkAPI update? i havent moved to the new build as i interpreted it as cant until new api is pulled to add support you needed

you only need to pull the latest api source code to compile it

6:21 AM

running it doesn't require an update

ohh ok

6:22 AM

and did it include the island explorer notes 10 levels? i know you added fj/gen2 in that last one

6:23 AM

or well i guess thats not the island only, its all maps with notes

it includes everything

API::Timer:: << what is this, unresolved symbol

#include <Timer.h>

FYI IDE is grumbling (but not an error) about that

lmfao

6:26 AM

the buff

6:26 AM

when added works

6:26 AM

but

6:26 AM

there's no HUD elements

well that defeats goal

6:27 AM

free esp

It has a range!

i see it on the far back ones still

6:27 AM

that thickness is configurable btw

I think it's 50meters or so

i got mine thinner lol

6:29 AM

but yeah this mods nice, good for seeing boss outlines when theres 4 billion particles going on and you can target lock so you keep boss HP on screen even when mouse isnt over them

6:29 AM

def a PVE based idea though lol

6:29 AM

i love pvp but im happy w/o the stress now, i got my fill of vanilla pvp

I wish those outlines were easier to make

raided and owned snow north, i consider that a solid ending

6:31 AM

um did this just give me another spyglass lol

6:31 AM

haha, your codes missing the engram check @substitute and its crafting one every login

6:32 AM

but overall seems to work good

that might be why it wasn't working

6:34 AM

->use on an engram is to craft

6:34 AM

I didn't have the materials in my inventory

6:34 AM

so it didn't craft

ok login code isnt working, didnt activate once i excluded engram

6:35 AM

yeah i got my recipe just 1 metal though im gonna switch that to fiber

6:35 AM

its ARK Omega theres enough early game struggles beyond basic kit items lol

did you check the engram like this?

6:36 AM

item->bIsEngram()() || item->bIsBlueprint()()

ah no i just did engram only

6:36 AM

it stopped the crafting

did you use two sets of () (edited)

yeah

6:37 AM

if (!item->IsA(spyGlassClass) || item->bIsEngram()()) continue;

is the item on your hotbar?

no

6:37 AM

goal was to not need it in hotbar

6:37 AM

long as one is in the inventory

6:40 AM

i feel like whole task should prob be delayed, the item ref is likely no longer valid

I got it to work

6:42 AM

            API::Timer::Get().DelayExecute([playerPawn]()
                {
                    static FString spyGlassBuffBlueprint = "Blueprint'/Game/Mods/AwesomeSpyglass/AwesomeSpyGlass_Buff.AwesomeSpyGlass_Buff'";
                    static FString spyGlassBlueprint = "Blueprint'/Game/Mods/AwesomeSpyglass/PrimalItem_AwesomeSpyGlass.PrimalItem_AwesomeSpyGlass'";

                    static UClass* spyGlassBuffClass = UVictoryCore::BPLoadClass(&spyGlassBuffBlueprint);
                    static UClass* spyGlassClass = UVictoryCore::BPLoadClass(&spyGlassBlueprint);

                    for (auto&& item : playerPawn->MyInventoryComponentField()->InventoryItemsField())
                    {
                        Log::GetLog()->error("item {}\n", item->NameField().ToString().ToString());
                        if (item->bIsEngram()() || item->bIsBlueprint()() || !item->IsA(spyGlassClass))
                            continue;
                        item->Use(true);
                        return;
                    }
                }, 1);

6:42 AM

you can move the lambda into a function call though to clean it up

lol literally what i was just testing

6:42 AM

why not 0 though to just be start of next tick

could be too soon, but you can try it

6:43 AM

1 you don't even notice though

6:43 AM

this all fires while you're still on the loading screen

and timer is in seconds and not game ticks right

it is in seconds

does it suffer desync if the server tick rate is falling behind? thats common issues plugin devs run into on our minecraft scheduler, human time vs 'time in ticks IF server is running at the expected ticks per second'

the game tick rate is decoupled from updates

ie passing 20*30 and expecting 30s on the dot

6:44 AM

k

updates (such as a 1 second delay) happen anywhere from 1

6:44 AM

to many seconds

6:44 AM

depending on the tick rate

6:44 AM

(like 1 tick / 100 seconds means 1 sec delay = 100 seconds)

6:45 AM

basically, every tick uses delta time

ok lemme rephrase, if server is expecting 30 TPS right i think i saw ARK does, but consistently runs at 15 ticks per second, is a delay of 10 consistently 20 or is it 10-11s~

it would be near 10-11

6:46 AM

each tick computes the time since the last tick

6:46 AM

and everything happens on real time time deltas

ok cool,just def important to understand how scheduler behaves for delays

anyways, 0 works fine

our scheduler api was built years ago and didnt factor in that stuff :/

6:46 AM

then combine in 12 year olds writing code

6:47 AM

fun times

this should work

(edited)

6:48 AM

std::bind let's us pass playerPawn to enableSpyGlassOnLogin

6:48 AM

because DelayExecute expects a function with no args

6:49 AM

API::Timer::Get().DelayExecute(std::bind(enableSpyGlassOnLogin, playerPawn), 0); is the same as like

            API::Timer::Get().DelayExecute([playerPawn]()
            {
              enableSpyGlassOnLogin(playerPawn);
            }, 0);

6:54 AM

I'll publish it on GitHub later

6:54 AM

and on the api site

6:56 AM

thanks, this has pretty much been my #1 goal for plugin, its just so annoying turning that on with how frequently you die in these op mod packs lol

6:57 AM

hence why most people run keep inventory mods since you die so damn much

Aikar

@Natsu how did you load the mod into dev kit to see that? can it be done for AwesomeSpyglass, you did SuperSpyglass which isnt same thing. I tried loading uasset file in dev kit but it didnt like it. compiled a ue4 compress app to de compress the .z asset.

it's been released to open source inside the Ark Modding community

yeah i figured when i looked at it, that it must likely include the devkit files

8:08 AM

got the plugin working for the correct mod now though with subs help

Hook_APrimalStructure_IsAllowedToBuild(APrimalStructure* _this, APlayerController* PC, FVector AtLocation, FRotator AtRotation, FPlacementData* OutPlacementData, bool bDontAdjustForMaxRange, FRotator PlayerViewRotation, bool bFinalPlacement)!.. I need a GetItemName function or some way to get the item name. please help me

Aikar

got the plugin working for the correct mod now though with subs help

Good to hear

data tags are simply a string array right, not a map? and up to users of data to filter out to only ones they know how to deal with

5:24 PM

ie if i want to store things on items or entities

Aikar

data tags are simply a string array right, not a map? and up to users of data to filter out to only ones they know how to deal with

custom data tags?

@substitute are you confirming to me that is what im looking for lol? the question mark makes me question if you are asking me a question. but like the spyglass mod said that modders can add a :Spyglass: data tag to add their own text to the spyglass - accessing those custom tags is what i was asking about.

3:55 PM

but i assume there isnt some Map<string, any> type data structure, gotta do it as Array<string> ?

I imagine it’s something made by the mod author directly

3:58 PM

Probably parses it

3:59 PM

That or it uses the custom data tags with the tag being named :SpyGlass:

4:01 PM

Looks like it’s an actual “tags” field on a Dino

@substitute what are you using to inspect that?

4:04 PM

curious where the full text of that box is set though, if the stored tag is just that ID

4:05 PM

ultimately would like to see if theres ways i can add my own text alongside of the mods text as well as store my own identifiers in the actor too

4:05 PM

in mc i just had generic persistent entity metadata as a <String, SomethingSerializable> map.

Aikar

@substitute what are you using to inspect that?

I found these pics from the modding discord (edited)

Aikar

but i assume there isnt some Map<string, any> type data structure, gotta do it as Array<string> ?

I could take a look if you want once i am home in the dev kit

4:21 PM

Was there a updated version from CrossChat, like a official one ?

updated in what sense, the kals on hub website works fine

4:23 PM

though this is prob wrong channel

Aikar

updated in what sense, the kals on hub website works fine

i am talking about, https://github.com/ark-mod/ArkCrossServerChat Kals is a non official plugin made by himself same as wooly's. I just dont like kals way of the chat order

GitHub - ark-mod/ArkCrossServerChat: Cross Server Chat support for ...

Cross Server Chat support for ARK Survival Evolved servers. - GitHub - ark-mod/ArkCrossServerChat: Cross Server Chat support for ARK Survival Evolved servers.

chat order? O.o what order is there beyond chronical order the messages was sent lol

Aikar

chat order? O.o what order is there beyond chronical order the messages was sent lol

Normally the chat is like "PlayerName - [TribeName]: Message " inside the message your allowed to use ArkML (https://ark.fandom.com/wiki/ArkML) Kals skips the first one and uses the message part instead so you get the : before every message

ArkML

Ark Markup Language (or ArkML for short) is a markup language seen in several instances within ARK. It is a type of SGML, and currently has only one known element, the "RichColor" element, which is used to add color to text. There is no official documentation for this markup language, and it may change at any time. When parsing ArkML, be sure th...

ah yeah iw as gonna look into seeing if i could hook after kals to remove that as its annoying

Aikar

ah yeah iw as gonna look into seeing if i could hook after kals to remove that as its annoying

well now you know the reason

yeah well ill just fix the problem

kals is a really nice solution

Aikar

yeah well ill just fix the problem

kals is a really nice solution

well message me if you do and il buy the plugin as well haha the only reason i did not buy it was that annoying : , using rcon cross chat now from spikeydragon

yeah i wanted the bi directional chat, and the playerlist is awesome

Aikar

yeah well ill just fix the problem

kals is a really nice solution

Does Kal’s work cross machines?

yeah

5:49 PM

just hwid for 20+ users so gotta buy multiple licenses

5:49 PM

but its free for < 20 players online

5:49 PM

so i havent needed to upgrade yet lol

Does it use any dependencies or rcon?

i dont think it needs rcon for chat but it does for commands

I’ve had the idea of replacing the chat system (on the server) with an irc type system

it lets you program buttons to do rcon like kick self, reload plugins, etc

So everything is real time with minimal overhead

its honestly quite a lot of good stuff combined in one package

5:50 PM

role syncs too

5:50 PM

ingame to discord

It uses mysql

5:51 PM

For the chat

5:51 PM

No thanks

5:51 PM

That’s a lot of added overhead and latency

5:51 PM

vs packet forwarding

man its chat you dont need nanosecond latency lol

5:53 PM

biggest concern would be if the queries are running main thread and adding too much time anytime a chat msg is sent

Sure but having a whole sql server for it

5:53 PM

That’s a LOT

5:54 PM

Imagine if you don’t use anything else that needs sql

sure in that regard, but lot of good plugins benefit from it

That’s a lot of additional overhead and security risks

Aikar

biggest concern would be if the queries are running main thread and adding too much time anytime a chat msg is sent

Even if they aren’t

5:55 PM

If you’re doing it safely

5:55 PM

With transactions

yeah i was surprised at fucking ASM default exposing rcon ports, they add firewall rules to expose rcon, and if you do what they suggest to manually set external IP, RCON binds to public IP instead of local too

SQL also isn’t real time so it’s all polling based

5:55 PM

Which has its own problems

5:55 PM

It’s the best solution currently available

5:56 PM

But not the best possible solution

Aikar

yeah i was surprised at fucking ASM default exposing rcon ports, they add firewall rules to expose rcon, and if you do what they suggest to manually set external IP, RCON binds to public IP instead of local too

That’s terrible

yeah thankfully i caught it quick and just disabled automatic firewall in asm and did it myself

I don’t even have my web server exposed publicly, it only allows cloudflare proxy ips

and also ignored their suggestion and set it back to let ark choose which keeps rcon on localhost only

And every game server I run goes behind wireguard

5:57 PM

And everyone gets a vps IP

5:57 PM

(Which nats back to my home server over wireguard)

people been asking for ark to add rcon bind support to keep it on localhost for years but looks like no action

It’s probably not that hard to fix

im just gonna keep my scale at 1 cluster per box and not worry about cross machine stuff

You could as a worst case

5:58 PM

Hook the actual network stack

but i prob will only do this 1 cluster as i want to focus ark2 IF it comes out

5:58 PM

we will see in 11 days

And force 127.0.0.1 for the rcon port

Aikar

but i prob will only do this 1 cluster as i want to focus ark2 IF it comes out

Lol

5:58 PM

It’s not coming out in 11 days

5:58 PM

No shot

news i mean

5:58 PM

2023 roadmap is being posted on mar 31

5:59 PM

per jeremy twitter

Expect it mid April

5:59 PM

Wildcard has zero ability to be on time

well thatll be a lol be late on releasing the other dates youll be late on

6:00 PM

but i feel like a roadmap they gotta say something about ark2or else thats a confirmation its not coming in 2023 lol

6:01 PM

heres hoping they release linux pdb and we can all move to linux only plugins instead of windows only

Aikar

heres hoping they release linux pdb and we can all move to linux only plugins instead of windows only

They won’t

6:03 PM

Also linux does use a pdb per se

6:03 PM

But it does have debug symbols

Aikar

heres hoping they release linux pdb and we can all move to linux only plugins instead of windows only

I'm just hoping WC keeps publishing Windows pdb when they make the switch to UE5 for ARK1 lol

well, if they dont everyone gets to use the joys of signatures!

6:03 PM

dust off my 15 year old library: http://aikar.github.io/SigScan/

6:04 PM

oh right that one was external use, i had local use version somewhere on my drive

6:06 PM

yes people used VB.net back then :shivers:

substitute

Sure but having a whole sql server for it

Kals chat is pretty nice. It's the only closed source plugin from another developer that I use on my servers. I've thought about eventually trying to make my own cross-server chat plugin though. Haven't gotten around to it yet but I've thought about making a DB-free solution.

even if diff solution exists it would still be a bind for me as i use so many things from it lol. discord playerlist, join logs, role syncs, discord actions to rcon commands, linking ingame name to discord to auto sync peoples name / tribe name

6:12 PM

2 way chat too

Natsu

well message me if you do and il buy the plugin as well haha the only reason i did not buy it was that annoying : , using rcon cross chat now from spikeydragon

I don't think it's possible to get rid of the leading ":" completely. But you could modify the messages to put stuff like the players name before the : so it looks a little more natural. I don't think you can modify the color before the : though, you might be stuck with the yellow font color.

that's what im lookin to do, put all the identity stuff on left hand side and keep msg on right. i dont mind the : to separate identity from msg

6:15 PM

[RAG] Name [Tribe]: Hello - though maybe rewrite server to be ( ) so its a diff wrapper. and maybe tribe on left hand side of name so its tags then name then msg

6:15 PM

i figure simple hook there then regex then rewrite structure

Aikar

even if diff solution exists it would still be a bind for me as i use so many things from it lol. discord playerlist, join logs, role syncs, discord actions to rcon commands, linking ingame name to discord to auto sync peoples name / tribe name

Yeah the in-game /online player list and the Discord player list are both pretty slick.

though can prob just split on space since its simple format

6:16 PM

though tribe names can have spaces

6:18 PM

though could kal fix this with just changing what hook is used to control entire line?

Yeah you could probably figure out some regex

or do you lose color potential on left hand side is why he pushes everything to msg?

I think Kal does it the way he does because you can modify the color of text inside the message itself, but I think it's not possible in the "player name" portion of the chat line before the :

lol ok as i just asked

6:20 PM

i assume at some point its sent as a simple FString

6:20 PM

that could be modified?

There's some client-side formatting and sanitizing that takes place after the message is received.

6:21 PM

That's where the : is added, on the client.

k so worse case move server identifier only to left hand side

6:21 PM

ah shit

6:22 PM

ok so every chat msg is from <Server>

6:22 PM

RAG: Aikar[Admin]: Hi would be better

I don't think it's possible to get rid of the leading ":" completely. But you could modify the messages to put stuff like the players name before the : so it looks a little more natural. I don't think you can modify the color before the : though, you might be stuck with the yellow font color.

Yellow is fine :p

There's some other function you can use to send messages to the chat box. But the font size is larger. Like what spikey dragoons RCON chat bot uses. (edited)

so we really just need a matching client side mod to proper fix it

Yeah you could probably make a mod+plugin solution to format it more nicely.

name mod "Chat Stripper" and just give vague description of "Strips the :" and see how many people think its uh more adult oriented lol.

6:32 PM

well glad we had this convo now can avoid wasting time trying to solve it with plugin

Aikar

name mod "Chat Stripper" and just give vague description of "Strips the :" and see how many people think its uh more adult oriented lol.

you could use the base of this tutorial i guess, https://docs.google.com/document/d/1jBVcXX6qzjCY3lKyO5fguRYsMWwq_3rXP6-9BS2mQ2U/edit

any know how i can change the CuddleType in a baby dino? im hooking Hook_APrimalDinoCharacter_UpdateBabyCuddling_Implementation and change the char NewBabyCuddleType to EBabyCuddleType::PET, it works, but the text in the dino no changes.

c++
void  Hook_APrimalDinoCharacter_UpdateBabyCuddling_Implementation(APrimalDinoCharacter* _this, long double NewBabyNextCuddleTime, char NewBabyCuddleType, TSubclassOf<UPrimalItem> NewBabyCuddleFood)
{
    NewBabyCuddleType = EBabyCuddleType::PET;
    APrimalDinoCharacter_UpdateBabyCuddling_Implementation_original(_this, NewBabyNextCuddleTime, NewBabyCuddleType, NewBabyCuddleFood);

}

If i click "E" for pet the dino, it works, but the text still saying "wants to be hand-fed comfort food: food type" any know how i can fix it?

Loki

}

If i click "E" for pet the dino, it works, but the text still saying "wants to be hand-fed comfort food: food type" any know how i can fix it?

You only want Pet ?

Natsu

You only want Pet ?

yes

8:11 PM

if i press "E" looking at the dino, it pets anyways, but text says wants to be hand-fed comfort food: food type (or the text when dino need to walk with you, it's still random), I need it would always say pet message. (edited)

did you log the output of the hook ?

Natsu

did you log the output of the hook ?

yes, it works, but the text not changes.

8:15 PM

as you can see, it is changed to "PET", but the text is still random.

Loki

yes, it works, but the text not changes.

there are 2 hooks i see one with _Implementation and one without , did you try both ?

Natsu

there are 2 hooks i see one with _Implementation and one without , did you try both ?

i will try one without (edited)

8:22 PM

oh it works, I didn't think there would be a difference between these 2, but it's worked. Thanks, sorry for the waste of time.

oh no worries

The one without is likely a multicast function so it will pass the args to both Server and Client, the _Implementation one would only be called on the server, so you would need to replicate the CurrentPetTypeField yourself with MulticastPropertyfunction

It's kind of cool how it works. When you have a net-replicated native UFunction, there's a Foo() function and a Foo_Implementation(). Foo_Implementation() is where the function is actually implemented. Foo() is a UE-generated function that basically just calls UObject::ProcessEvent(). ProcessEvent() figures out where the function is supposed to run (on the server, the owner client, or on all clients) and invokes it there. APrimalDinoCharacter::UpdateBabyCuddling() is a multicast UFunction, so it gets invoked on the server and all clients. Another case where you see _Implementation() is when there's a base class with a UFunction implemented in C++ that can be overridden with a Blueprint graph in a child class. In that case, the generated Foo() function calls UObject::FindFunction(), which returns the BP-override UFunction if it exists or the native Foo_Implementation() UFunction. Then Foo() calls ProcessEvent() with whatever UFunction it found. (Like the DoMate() function we talked about in DM @Loki).

thanks for the explication GOGHEART1

this CreateCloneFertilizedEgg on APrimalDinoCharacter the method used for all egg making and not something special to clones right?

6:10 AM

suspecting the clone word just means its cloning parents

6:10 AM

finally able to see the voodoo of the mutation code lol

Aikar

this CreateCloneFertilizedEgg on APrimalDinoCharacter the method used for all egg making and not something special to clones right?

I think that function just creates a clone as it says, but that egg is clean from mutations, so it just spawns the same dino, just baby

9:03 PM

By the looks of the decompiled code

this is the code that seems to trigger the mutations, i see the mutation logic in it

9:04 PM

i wanted to make sure didnt need to hook multiple places to control mutations

You just need to hook DoMate, and change values on the dino before calling original

planning to take a diff route, of modifying that FItemNetInfo it uses for the < 20 checks

9:06 PM

bool isCreateEgg = false;
    FItemNetInfo* Hook_UPrimalItem_GetItemNetInfo(UPrimalItem* _this, FItemNetInfo* result, bool bIsForSendingToClient) {
        return UPrimalItem_GetItemNetInfo_original(_this, result, bIsForSendingToClient);
    }

    ADroppedItem* Hook_APrimalDinoCharacter_CreateCloneFertilizedEgg(APrimalDinoCharacter* dino, FVector AtLoc, FRotator AtRot, TSubclassOf<ADroppedItem> DroppedItemTemplateOverride) {
        isCreateEgg = true;
        auto result = APrimalDinoCharacter_CreateCloneFertilizedEgg_original(dino, AtLoc, AtRot, DroppedItemTemplateOverride);
        isCreateEgg = false;
        return result;
    }

9:07 PM

i want to make it consider the female > 20 too if the male is, to cut off mutations completely once it hits 20

Aikar

this is the code that seems to trigger the mutations, i see the mutation logic in it

I'm pretty sure the mutations are added in the DoMate_Implementation function, the create clone fert egg just copies the dino values into the egg, without actually incrementing any mutation counter

theres code here doing the if < 20 add +1 though

9:07 PM

DoMate ^^

ok so guess there is diff place

Nevermind it does the same lol sorry

          iVar3 = rand();
          bVar2 = 0.5 < (float)iVar3 / 32767.0;
          local_34c = (uint)bVar2;
          if ((((bVar2) && (local_1c8.EggRandomMutationsFemale < *(int *)(this + 0x2018))) ||
              ((!bVar2 && (local_1c8.EggRandomMutationsMale < *(int *)(this + 0x2018))))) &&
             ((float)(uint)local_1c8.EggNumberOfLevelUpPointsApplied[local_35c] +
              *(float *)(this + 0x2024) <= 255.0)) {
            local_1c8.EggNumberOfLevelUpPointsApplied[local_35c] =
                 (uchar)(longlong)
                        ((float)(uint)local_1c8.EggNumberOfLevelUpPointsApplied[local_35c] +
                        *(float *)(this + 0x2024));
            if (bVar2) {
              local_1c8.EggRandomMutationsFemale = local_1c8.EggRandomMutationsFemale + 1;
            }
            else {
              local_1c8.EggRandomMutationsMale = local_1c8.EggRandomMutationsMale + 1;
            }

theres def mutation logic going on here

9:09 PM

in the create clone one

yeah missed that bit when reading

so that was ultimately the question what scenarios makes it use this one, is the doMAte maybe for gestation?

DoMate does egg and gest (edited)

9:10 PM

Both functions are almost identical when creating the egg data, but one does not call the other and viceversa

so i guess question is wtf scenario does the create clone method get used, by name feels like doMate would be primary

Yeah DoMate is what handles mating at full, I feel like the clone function is mainly for modders or other type of scenarios like missions or who knows

im showing doMAte as a small FindFunction method?

9:15 PM

or is it on a diff object than dino

9:15 PM

i dont seee this same logic in _impl

It's in APrimalDinoCharacter, there's 2 of them. APrimalDinoCharacter::DoMate is an engine implementation, and APrimalDinoCharacter::DoMate_Implementation has the actual logic

i think ghidra did a worse job on this method or something

I used ghidra a while ago and I didn't like how it handled the ark decompile

I use IDA Freeware which is free and has a cloud based decompiler (edited)

oh ill need to try that out, can IDA just dump it all so can open it in damn IDE (Even if not compilable)?

I know you can export a header with all types, but I am not sure if you need the IDA pro version to dump .c files

9:18 PM

I once dumped a .c file and was like 2gb file lol

its interesting ghidra got the more human readable names for the clone method but not this one

By the way, did a full ida search and the clone egg function is not called at all on the C++ code of the game

oof

9:20 PM

well my goal was to simply say if (creatingEgg) { if either male or female >= 20, consider both sides 20. so people can get 20 per line then its cut off.

9:20 PM

so figure manipulate the FITemNetinfo

Yeah the code of the clone egg func is copy pasted into DoMate lol, maybe inlined at compile time

9:21 PM

You could hook DoMate, call original first, do an sphere overlap at the dino location, find the egg and modify the item info

9:22 PM

Or as you did with isCreateEgg bool in function, hook DoMate and StaticDropitem from UPrimaInventoryComponent, and check wether that bool is true do modify the item to drop (edited)

hmm i dont see DoMate_Implementation in the Actor.h file, will DoMate call it still? ultimately my approach should still work fine in DoMate i think

Yeah possibly, I think I hook DoMate for modifiying breeding stuff

what is the Rolls field?

The amount of mutation points it gives when the chance is successful (edited)

10:05 PM

Although I am not 100% sure

I've never looked at mutation code, but APrimalDinoCharacter has MaxAllowedRandomMutations, RandomMutationRolls, RandomMutationChance, and RandomMutationGivePoints fields. Normally offspring have 3 chances at mutations (can be on different stats).

10:13 PM

Also heads up with APrimalDinoCharacter::DoMate(), that's a function that can be overridden by child classes of APrimalDinoCharacter with Blueprint functions.

10:13 PM

Although I think Ferox is the only dino that actually has its own implementation.

Aikar

so i guess question is wtf scenario does the create clone method get used, by name feels like doMate would be primary

You can also search for where functions are called in the dev kit. Open a Blueprint that has graphs, go to the "Graph" tab, right click on a function name in the left hand pane and select "Find References", then in the "Find References" pane replace the function name with the function you want to search for and de-select the "Find in current Blueprint only box". (Anyone know if there's a better way?)

11:15 PM

oh so thats used for nests too? weird it has mutation code, does that mean eggs in nest technically could mutate lol?

Idk, if wild nest eggs can have mutations it's news to me lol

well theres the code for processing mutations in that method, unless the wild dinos have the 20 counter set to 0

Well theres a "Num Mutations to Add" argument it looks like

11:17 PM

set to 0

ah yeah

Hi, any know how i can hook BPStaticCreateBabyDino? if i use Hooker Creator i get this code

c++
DECLARE_HOOK(APrimalDinoCharacter_APrimalDinoCharacter*, APrimalDinoCharacter*, APrimalDinoCharacter*, UWorld*, TSubclassOf<APrimalDinoCharacter>, FVector*, float, char*, char*, float, int, TArray<FDinoAncestorsEntry>*, TArray<FDinoAncestorsEntry>*, int, int);

APrimalDinoCharacter*  Hook_APrimalDinoCharacter_APrimalDinoCharacter*(APrimalDinoCharacter* _this, UWorld* theWorld, TSubclassOf<APrimalDinoCharacter> EggDinoClassToSpawn, FVector* theGroundLoc, float actorRotationYaw, char* EggColorSetIndices, char* EggNumberOfLevelUpPointsApplied, float EggTamedIneffectivenessModifier, int NotifyTeamOverride, TArray<FDinoAncestorsEntry>* EggDinoAncestors, TArray<FDinoAncestorsEntry>* EggDinoAncestorsMale, int EggRandomMutationsFemale, int EggRandomMutationsMale)
{
   return APrimalDinoCharacter_APrimalDinoCharacter*_original(_this, theWorld, EggDinoClassToSpawn, theGroundLoc, actorRotationYaw, EggColorSetIndices, EggNumberOfLevelUpPointsApplied, EggTamedIneffectivenessModifier, NotifyTeamOverride, EggDinoAncestors, EggDinoAncestorsMale, EggRandomMutationsFemale, EggRandomMutationsMale);
}

ArkApi::GetHooks().SetHook("APrimalDinoCharacter.APrimalDinoCharacter*", &Hook_APrimalDinoCharacter_APrimalDinoCharacter*, &APrimalDinoCharacter_APrimalDinoCharacter*_original);

ArkApi::GetHooks().DisableHook("APrimalDinoCharacter.APrimalDinoCharacter*", &Hook_APrimalDinoCharacter_APrimalDinoCharacter*);

but dont compiles.

11:11 PM

i changed it to:

c++
DECLARE_HOOK(APrimalDinoCharacter_StaticCreateBabyDino, APrimalDinoCharacter*, APrimalDinoCharacter*, UWorld*, TSubclassOf<APrimalDinoCharacter>, FVector*, float, char*, char*, float, int, TArray<FDinoAncestorsEntry>*, TArray<FDinoAncestorsEntry>*, int, int);

APrimalDinoCharacter* Hook_APrimalDinoCharacter_StaticCreateBabyDino(APrimalDinoCharacter* _this, UWorld* theWorld, TSubclassOf<APrimalDinoCharacter> EggDinoClassToSpawn, FVector* theGroundLoc, float actorRotationYaw, char* EggColorSetIndices, char* EggNumberOfLevelUpPointsApplied, float EggTamedIneffectivenessModifier, int NotifyTeamOverride, TArray<FDinoAncestorsEntry>* EggDinoAncestors, TArray<FDinoAncestorsEntry>* EggDinoAncestorsMale, int EggRandomMutationsFemale, int EggRandomMutationsMale)
{
   Log::GetLog()->info("CreateBabyDino");
   return APrimalDinoCharacter_StaticCreateBabyDino_original(_this, theWorld, EggDinoClassToSpawn, theGroundLoc, actorRotationYaw, EggColorSetIndices, EggNumberOfLevelUpPointsApplied, EggTamedIneffectivenessModifier, NotifyTeamOverride, EggDinoAncestors, EggDinoAncestorsMale, EggRandomMutationsFemale, EggRandomMutationsMale);
}

ArkApi::GetHooks().SetHook("APrimalDinoCharacter.StaticCreateBabyDino", &Hook_APrimalDinoCharacter_StaticCreateBabyDino, &APrimalDinoCharacter_StaticCreateBabyDino_original);

ArkApi::GetHooks().DisableHook("APrimalDinoCharacter.StaticCreateBabyDino", &Hook_APrimalDinoCharacter_StaticCreateBabyDino);

And "CreateBabyDino" shows sucess, but i cant find the way to get the dino after it creates.

11:11 PM

Because if i do

c++
APrimalDinoCharacter* Dino = APrimalDinoCharacter_StaticCreateBabyDino_original(_this, theWorld, EggDinoClassToSpawn, theGroundLoc, actorRotationYaw, EggColorSetIndices, EggNumberOfLevelUpPointsApplied, EggTamedIneffectivenessModifier, NotifyTeamOverride, EggDinoAncestors, EggDinoAncestorsMale, EggRandomMutationsFemale, EggRandomMutationsMale);

server crash. And if i try to modify the "_this" variable, it crash in the return line.

c++
_this->TamedNameField() = FString("Test");
return APrimalDinoCharacter_StaticCreateBabyDino_original(_this, theWorld, EggDinoClassToSpawn, theGroundLoc, actorRotationYaw, EggColorSetIndices, EggNumberOfLevelUpPointsApplied, EggTamedIneffectivenessModifier, NotifyTeamOverride, EggDinoAncestors, EggDinoAncestorsMale, EggRandomMutationsFemale, EggRandomMutationsMale);

With this code, it crash in the return line.

Q: Is it possible to store a unordered_map inside another unordered_map? This code will not compile for me

c++
struct AwardData
{
    float Amount{};
    bool bUseTokens{};
    std::string sTokenName{};
    int min_level{};
    int max_level{};
    int KillsNeeded{};
};

typedef std::unordered_map<FString, std::vector<AwardData>> FStringAwardDataMap;
typedef std::unordered_map<uint64, FStringAwardDataMap> SteamIdBPAwardDataMap;

SteamIdBPAwardDataMap PlayerDinoRewardsMap3{};

const FString bp = "Some random dino blueprint";
const uint64 steam_id = 13213682736873613;

if (PlayerDinoRewardsMap3.size() > 0)
{
    auto& result = PlayerDinoRewardsMap3.find(steam_id);
    if (result != PlayerDinoRewardsMap3.end())
    {                                                            
        FStringAwardDataMap& awardMap = result->second;
        auto& result2 = awardMap.find(bp);   // this line won't compile, when i try to search for FString in FStringAwardDataMap
        
    }
}

Thank you in advance pepeold

Think you'll have to implement your own hash function for that.

1

7:01 AM

https://github.com/SubstituteR/MoarPtr/blob/main/function_ptr.h#L113

MoarPtr/function_ptr.h at main · SubstituteR/MoarPtr

A header library in C++ that adds a smart container for different types of pointers. - MoarPtr/function_ptr.h at main · SubstituteR/MoarPtr

yeah, changing it to std::map instead does compile

Weird.

I thinks it's because the FString has no hash function, but it does have a < (for a std::map)

TheMollusk

I thinks it's because the FString has no hash function, but it does have a < (for a std::map)

Hence the need for a custom std hash function

10:38 AM

Which we should probably add

10:38 AM

A shortcut could be to map FString hash to std::string hash

There's also UE's TMap, which is another hash table. TMap already supports FString keys. I haven't used ArkServerApi's TMap much, but the headers are there so I assume it all works? Types implement GetTypeHash() for UE hash containers. FString's GetTypeHash() just returns a 32-bit CRC.

I think someone fixed it a while ago.

6:18 PM

The time I tried to use them, before it was fixed it would create multiple pairs of the same key-value lol (edited)

For several months last year I ran my own plugins (not ArkServerApi-based) on a Linux server cluster. But I switched back to Windows. Too many things that are much easier to do with the pdb and some (non plugin-related) bugs on the Linux server that you don't get on the Windows server (although there's some things I like better about the Linux server too) (edited)

a newbie question, why couldn't the api run on linux? is it because the code would have to be written differently? it's something I've always wondered xD

Stevie senpai

a newbie question, why couldn't the api run on linux? is it because the code would have to be written differently? it's something I've always wondered xD

Well the big reason is that ArkServerApi plugins use debug symbols and only the Windows version of the ARK server ships with those. Plus existing plugins are often written specifically for Windows.

1

3:08 AM

The plugins I wrote for Linux were based mostly off the Unreal Engine reflection system, but that doesn't give you access to as many fields and functions as you get with debug symbols.

1

so ark has a different version of files to host a linux server?

Yes. There's a version of the server executable file for Windows and one for Linux. WildCard ships the Windows version with debug symbols (the .pdb file), which is what ArkServerApi uses to get variable offsets and function addresses. The Linux build doesn't come with debug symbols.

If the ARK UE5 remaster doesn't ship with debug symbols and ArkServerApi gets ported to support it, maybe that's an opportunity to re-architect it in a way that provides support for both platforms.

the executable I imagined that if it was different because normally if I'm not wrong linux does not run .exe, I was going to ask that because it was not carried or injected that pdb (from ignorance) in linux but I just saw that it is owned by windows so little compatibility I think .... F

that would be great, that would be the end of the "no, you can't put plugins because it's a linux host" thing

3:28 AM

thank you very much for answering my stupid questions mollusk

Maybe there won't even be a Linux server for the remaster

‍♂️ Like Owl said in announcements the other day, lots of unknowns

Turns out when the studio doesn't know what they're doing, everyone relying on them can't know either thonkRolly

TheMollusk

The average skill level of this community would make porting the api without a PDB arduous to say the least.

10:09 AM

We really need better tutorials and documentation

10:09 AM

And maybe some links to learning modern C++

10:11 AM

I don’t mean it in any rude way, there’s just a lot of newer programmers that join here and using UE reflection takes a pretty high level of knowledge of the architecture and language.

After doing the low level part, a more user friendly interface could be implemented perhaps?

Yeah that's the point of ArkServerApi right? Personally, I haven't had to learn how to process a pdb file from C++ because ArkServerApi does it for me. Should be the same situation for most plugin developers whether the API is based on pdb or UE reflection or signature detection or whatever.

Yeah, then the fields we can access by reflection system could be used somewhat similar to the fields now, wrappers functions that gets us what we really need and abstract the low level stuff

substitute

The average skill level of this community would make porting the api without a PDB arduous to say the least.

it would just require all the getters be exposed as signature scans instead of offset pdb lookups, so the core team would just have to put in a lot more work to expose things. the FFXIV community did pretty well there. I have a 15 yr old sig scan library for it too lol. basic principles of the signature scan would still be the same today. Just the PDB def makes it easier for people to define their own structs w/o having to get it officially added. Expose the structs/sigs as a separate repo that people can contribute to easy.

6:51 PM

finding sigs though thats one hell of a job

My friend has a signature scanner that uses AVX to increase performance

I'd imagine the reflection system can be leveraged with a minimal amount of signature scanning (that's the case in the current engine at least). Then it's easy to generate a useful set of partial definitions for native class variables and functions and for basically everything in BP-generated classes. Discovering signatures for unreflected stuff would be painful, but maybe in some cases at least there will be some additional clues available if WC copies a lot of their current code. (edited)

Is there a way to find out what Folder a UPrimalItem is currently sitting in, whether it be a custom folder of one of the predefined folders (when in folder view)? I did some initial searching but haven't come up with much.

6:40 PM

I did some snooping around in IDA and found this function, looks promising, but when I checked the API it doesn't exist.

item->ItemFolderPathField() (edited)

it's not coming up for me

You need to add it then

that method can be used to move to a folder by name yeah? i was wanting to make some sorting command to let users sort regex patterns to folders

7:23 PM

and is there a way to change an items name? i was thinking if we can let users rename their personal armor sets, then it wont get caught in regex to move other stuff, as i want to make it so it can drop newly aquired armor thats not your primary set but be able to exclude your personal armor sets

Pelayori

You need to add it then

Okay I added the struct and made UPrimalItem inherit from IDataListEntryInterface

c++
struct IDataListEntryInterface
{        
    TArray<FString>& CustomFoldersNamesField() { return *GetNativePointerField<TArray<FString>*>(this, "UPrimalItem.CustomFoldersNames"); }
    TArray<FString>& ItemFolderPathField() { return *GetNativePointerField<TArray<FString>*>(this, "UPrimalItem.ItemFolderPath"); }
};

it crashes on this line: auto ItemFolderPaths = currentItem->ItemFolderPathField();

tyvm!

Hi, I'm currently struggling to read the Transform from an Actor inside a submap, ANPCZoneManager in this case. Neither one of ANPCZoneManager -> AInfo -> AActor does seem to have a transform property/field, then I tried NPCzoneManager->GetTransform(&transform); but after looking into it this just seems to use NPCzoneManager->ActorToWorld(&transform); which takes the value from USceneComponent if it exists, but checking USceneComponent* component = NPCzoneManager->RootComponentField(); gives a nullptr for me so it kinda makes sense that ActorToWorld does not work properly. It just gives all zeros for x,y,z which could also be related to my followup question. So the first question would be where did I overlook to look? And a followup how do I use the m128 datatype inside FTransform correctly? Searching the Internet a bit this seems to be pretty low level and dependent on CPU and compiler etc (or I read that wrong) and on top of that in this case a single \m128 should actually represent 3 values (x,y,z) and not a single value.

Is it possible for two timers to interfere with each other from two separate plugins if they have the same name? For example if I unload a timer called "run_events" on one plugin and the other has the same timer name, will it disable both of them by chance? I keep loosing a timer on 1 of my plugins.

Ya, i'm pretty sure they are all stored in a generic list.

Lethal

Ya, i'm pretty sure they are all stored in a generic list.

Yeah they’re keyed by name I’m pretty sure

okay, makes sense lol. once I really thought about it I figured it would all be ran by the API as a list, seems to be working now, I will make sure to make them very unique names from now on.

How to access class FName?

What do you mean by access?

I'm pretty new to learning this. But when I understand how to add .h and libraries of other plugins But still do not understand how to create

11:18 PM

https://github.com/K07H/AutoFillCrops/blob/main/AutoFillCrops/AutoFillCropPlots.cpp#L7 @OSubMarin this code is O(n) complexity for performance, may I recommend this approach instead: https://gist.github.com/aikar/9c179f0979b4237a341dd0cade8671fe Then you can static BlueprintCache bp("blah"); then bp.Get();

11:21 PM

as it seems your uses are static BP's, i could see using a map if it was open ended on what BP's was referenced

11:22 PM

though that current code is using a map but seems to iterate entire collection instead, should at least be using map based operations instead of iteration

thank you but that's not needed for what it does

1:14 AM

the goal is to have a map of cached loaded blueprints

1:14 AM

that's a utility function that I use in various project

1:15 AM

it has negligible impact on performance (edited)

1:16 AM

better to recode this function: UVictoryCore::ServerOctreeOverlapActorsClass

1:22 AM

also I'm not even playing Ark since more than a year, and I heard they plan to shutdown servers and stop releasing updates and content for it so I don't have interests in coming back

1:24 AM

it will just die slowly now :3

You should not use pch, disable precompiled headers in the project settings and delete those pch files

Should this be changed? I've seen other projects use it. stdafx.h but never saw the file stdafx.h

It's not mandatory to use an SQL server tho, I don't use SQL server. You can simply store in a file asynchronously. It depends of what you want to achieve. (edited)

@OSubMarin SQL is def much desirable, im far from beginner in this stuff, just put here since beginning on using mysql in c++. If you only see the crazy amount of code I have built in minecraft with DB and Metadata powers

framework is key, and also building things as a linked cluster, file based is horrible, as you also have the windows kernel being super slow there. With MySQL you get to buffer things in memory and improve latency.

6:28 PM

i just did some file based status reporting as a quic hack until i get mysql working in my plugin lol

6:29 PM

but that modern mysql lib people use is not pooled, and you absolutely need to use pools when dealing with multiple threads as you should never share a mysql connection over multiple threads. i see people naively doing that in minecraft all the time

6:32 PM

trying to get this superior lib to work, does anyone know if those .lib files in arkshops lb folder is just an older mysql connector C? i was using those, but getting this which i also was getting on the modern sql too until i updated it to the newer one:

nah just use async file operations, works great. It only depends on what you want to achieve

(and also what you feel more comfortable with) (edited)

8:34 PM

If you think SQL only stores data in memory, well... surprise! it stores its data to files asynchronously ^^

yeah ive been doing this for 20 years, im aware

but it does it much more efficiently (edited)

8:48 PM

just been 15 years since i did C++ before this so still got a bit to learn on this language

it depends on what you want to achieve (I suppose you're not processing millions of requests) (edited)

9:03 PM

calling a function (which will then do async processing) is faster than calling an SQL server

of course, talking about data storage though, of shared state data you want to be able to persist and let other things read.

9:08 PM

but not really relevant here, i absolutely will be using mysql

if you think it fits better for your usage alright then

9:09 PM

you didn't say what you want to do so I was just giving an idea since I saw "found a better mysql client than what everyone seems to be using"

OSubMarin

If you think SQL only stores data in memory, well... surprise! it stores its data to files asynchronously ^^

Oh boy do I have a surprise for you

9:09 PM

https://dev.mysql.com/doc/refman/8.0/en/memory-storage-engine.html

what is the surprise?

If you use that, MySQL stores everything in memory only

9:11 PM

No disk operations

I see, then it could be smart to enable this if you don't have too much data to store

9:13 PM

depends on what you're trying to do because if you start storing images and videos with this your memory will be full very quick

even with standard dbs, RDBMS has super optimized crud operations to optimize disk access, reads hit memory cache and dont touch disk. writes can be bundled by pages. right now because i didnt have db setup yet im writing tiny text files 1 per metric to export, which then suffers with windows file locking too, and writing tiny small files is pure evil in terms of performance. I will be moving this over to db once I get this all polished, which then would let me run my monitoring code on a different machine too. as long game ima prob end up building a linux box to move db/management code over to.

9:20 PM

as ive spent past 3 days cursing windows, life was so nice when i was windows free for 10 years

1

9:23 PM

wrote code to detect crashed servers, and last night it was looking good when ran it myself, used taskslist and dumped processes, and used the window title to find desired process to folder. well, when i turned it on to a windows task scheduler, the task scheduler now cant see the window titles, and broke it, and ended up spawning duplicate server processes. thankfully found a powershell alternative to dump actual full process binary path and that solved the issue.

I think the game will die quickly tho, because if they don't provide bugfixes and cheat-fixes it will become unplayable game considering the amount of cheaters :/

Unless you're managing small community servers or pve servers maybe.

someone suggested maybe buffs can be a vector to store data

9:58 PM

i want the data stored in the actor data so that it is self maintaining for cleanup when dino dies etc

9:58 PM

and not external data sotre

9:59 PM

also persisting between podding (edited)

OSubMarin

Maybe they will continue to update it, I just doubt about it :p

They have said they will do that

9:59 PM

Bug fixes and critical issues

9:59 PM

Just not content

9:59 PM

Content updates will be shifted to ASA

This also assumes ASA won’t be a steaming pile of shit at release

1

its WC, of course it will be

Release 1 piece of content on time without bugs challenge (impossible)

"UE5 is much harder to adapt to than we expected" didnt they say something along that lol

Pelayori

They have said they will do that

Thanks, I didn't know.

so they of course will bungle it

They’re gonna customize the engine again and then have to release Ark 1.5.5 in 6 years

yeah im shocked they did it, conan devs were like yeah we hacked this shit too much it aint happening

I’m willing to actually bet on it

10:01 PM

Wildcard simply can not follow good coding practices

i wouldnt say its about coding practices, though they may have flaws there too, its about when you depend on an upstream framework/library, and you need to modify it, ensuring your modifications are done in a maintainable way, keeping your diffs isolated from baseline so they are re-applyable, and when you rebase upstream, knowing how to re-apply your desired changes on top of the new base, then keep your implementation separate from maintainenance of the fork. have to say we did a lot of things well in the minecraft dev scene, we literally have over 1000~ patch files on top of the minecraft base game and maintained it for a decade. (well, it wasnt 1k back then, I blew things to larger scale starting in 2016 lol)

10:06 PM

and its a fork of a fork of a fork of a fork of a fork

10:07 PM

Minecraft -> Craftbukkit -> Spigot -> Paper -> My personal fork - plugin is completely separate repo.

10:07 PM

if they kept their changes isolated updating to new engines is much more viable

Aikar

if they kept their changes isolated updating to new engines is much more viable

Yes, this is part of proper coding practices

10:08 PM

Maintaining a downstream fork isn’t something new, a lot of projects do it and they do it much better than WC.

id consider it more project/change management best practices, cause the code can still be the same both ways, its just organization of managing those changes with updating maintenance in mind

10:10 PM

maybe if wanna umbrella term it, engineering best practices

10:13 PM

i feel like it maybe an industry weakness though, they look at it as start with a copy of ue as your starting repo files, rather than a blank repo with ue as a submodule

If you leave the base classes alone

10:14 PM

It’s usually a non-issue

10:15 PM

Anyways a lot of core ark design

10:15 PM

Screams prototype that never was fixed

10:15 PM

Stuff like multi-use entries

you mean like keeping the game named the hello world app name lol...

10:20 PM

Is that all the error output you got? What does your DllMain() look like? Your SET_HOOK and DISABLE_HOOK macros? "Failed to find hook" is printed when DisableHook() is called and your detour isn't found in the installed hooks.

DllMain

#include "includes.h"
#include "init.h"

BOOL APIENTRY DllMain(HMODULE hModule, DWORD ul_reason_for_call, LPVOID lpReserved)
{
    switch (ul_reason_for_call)
    {
    case DLL_PROCESS_ATTACH:
        Load();
    case DLL_PROCESS_DETACH:
        Unload();
    }

    return FALSE; //Nothing happened!
}

Hatya

DllMain

#include "includes.h"
#include "init.h"

BOOL APIENTRY DllMain(HMODULE hModule, DWORD ul_reason_for_call, LPVOID lpReserved)
{
    switch (ul_reason_for_call)
    {
    case DLL_PROCESS_ATTACH:
        Load();
    case DLL_PROCESS_DETACH:
        Unload();
    }

    return FALSE; //Nothing happened!
}

you never return true

11:15 PM

the switch runs the code for Load and Unload, and then returns false

11:16 PM

https://learn.microsoft.com/en-us/windows/win32/dlls/dllmain

DllMain entry point (Process.h) - Win32 apps

An optional entry point into a dynamic-link library (DLL). When the system starts or terminates a process or thread, it calls the entry-point function for each loaded DLL using the first thread of the process.

11:16 PM

// Return FALSE to fail DLL load.

11:17 PM

You can probably safely change return FALSE; //Nothing happened! to return TRUE; //Nothing happened! as you don't have any logic to abort loading when something fails

Hum i see,

BOOL APIENTRY DllMain(HMODULE hModule, DWORD ul_reason_for_call, LPVOID lpReserved)
{
    switch (ul_reason_for_call)
    {
    case DLL_PROCESS_ATTACH:
        return Load();
    case DLL_PROCESS_DETACH:
        return Unload();
    }

    return FALSE; //Nothing happened!
}

Better ?

no, Load() probably isn't returning anything

11:18 PM

you would have to explicitly return from Load() (edited)

Yes i've change my load and unload

Change return FALSE to TRUE

11:18 PM

there's literally no reason as-is to abort loading your DLL

11:18 PM

you have zero initialization dependencies as far as I can tell

DECLARE_HOOK(validateName, void, AShooterPlayerState*, FPrimalPlayerCharacterConfigStructReplicated*);

void Hook_validateName(AShooterPlayerState* _this, FPrimalPlayerCharacterConfigStructReplicated* playerCharacterConfig)
{
    Log::GetLog()->info("Plugin On Hook.");
    return validateName_original(_this, playerCharacterConfig);
}

BOOL Load()
{
    Log::Get().Init("Init Plugin.");
    Log::GetLog()->info("Plugin INIT.");
    SET_HOOK("AShooterPlayerState.ServerRequestCreateNewPlayer_Implementation", validateName);
    return true;

}

BOOL Unload()
{
    DISABLE_HOOK("AShooterPlayerState.ServerRequestCreateNewPlayer_Implementation", validateName);
    return false;
}

Hatya

DECLARE_HOOK(validateName, void, AShooterPlayerState*, FPrimalPlayerCharacterConfigStructReplicated*);

void Hook_validateName(AShooterPlayerState* _this, FPrimalPlayerCharacterConfigStructReplicated* playerCharacterConfig)
{
    Log::GetLog()->info("Plugin On Hook.");
    return validateName_original(_this, playerCharacterConfig);

BOOL Load()
{
    Log::Get().Init("Init Plugin.");
    Log::GetLog()->info("Plugin INIT.");
    SET_HOOK("AShooterPlayerState.ServerRequestCreateNewPlayer_Implementation", validateName);
    return true;

}

BOOL Unload()
{
    DISABLE_HOOK("AShooterPlayerState.ServerRequestCreateNewPlayer_Implementation", validateName);
    return false;
}

This is wrong

11:19 PM

Unload should return true for DllDetach to ensure the dll is properly unloaded

11:19 PM

since you are returning true literally from Load and (will be) from Unload

11:19 PM

there's no reason to return anything from those functions at all

11:19 PM

as they're effectively the same as just returning true in dllmain instead of false

Part of the issue was you're falling through switch cases. When the DLL is loaded, you call Load(), then fall through to Unload(), then return false, then DllMain was called again because you returned false, then Unload() is called but there's nothing to unload.

this too, though it wouldn't be an issue with a return statement

11:20 PM

as a return statement breaks all execution

Double dinos on their kill to learn hooks and some spawning stuff.

hum they is anyway to get actor unique id ? for dino for example

Yes. They have a field that contains that info. I think it’s called DinoID but I can’t remember exactly off the top of my head.

For APrimalDinoCharacter (I've used this one so I know it works): https://github.com/ServersHub/Framework-ArkServerApi/blob/master/version/Core/Public/API/ARK/Actor.h#L6907 For AActor you can try this (I've not tested this one so I'm not sure what you will get): https://github.com/ServersHub/Framework-ArkServerApi/blob/master/version/Core/Public/API/ARK/Actor.h#L832 ---- (edited)

2:58 PM

Given a AActor* theActor; you can do:

if (theActor != nullptr && theActor->IsA(APrimalDinoCharacter::GetPrivateStaticClass())) // Check if given actor is a valid dino.
{
    APrimalDinoCharacter* theDino = static_cast<APrimalDinoCharacter*>(theActor);
    int theDinoID1;
    int theDinoID2;
    theDino->GetDinoIDs(&theDinoID1, &theDinoID2);
    // Do something with the dino IDs here...

isnt it better to use the exports instead of dllmain methods? imo should just recommend people to switch instead of working around issues with dll main entry points

Aikar

isnt it better to use the exports instead of dllmain methods? imo should just recommend people to switch instead of working around issues with dll main entry points

Interresting, can you explain me the difference ?

waiting for threads to join isnt allowed in dllmain ive read

3:59 AM

theres more restrictions in there

4:00 AM

and to my understanding theres no benefit to using the dllmain either

hum i see, and it's require lot of change to move to export from dllmain ? (edited)

nope

4:01 AM

extern "C"  __declspec(dllexport) void __fastcall Plugin_Init() {
    SA::Load();
}
extern "C"  __declspec(dllexport) void __fastcall Plugin_Unload() {
    SA::Unload();
}

4:01 AM

just define those 2 exports

4:06 AM

also @Hatya this Log::Get().Init("Init Plugin."); is suppose to be your plugin name, it names the logger

Where can I find more information or codes?

@Aikar thx !

I've change for init function
if i change for export, i've to only keep myplugin.cpp & myplugin.h and in bottom (or top ?) of add the export ?

Hum, which hook you use to start "recurring" task after server launch ? Some of hook can have performance issue ?

Yes a poorly coded hook can cause performance issues. Depends on how often you would like it to reoccur.

yeah you have to consider how often is said hook called. then if its super 'hot', be careful what you do in it.

4:09 PM

add a log line, if your console is absolutely bombed, be cautious

4:09 PM

- if i change for export, i've to only keep myplugin.cpp & myplugin.h and in bottom (or top ?) of add the export ? I think you can just put this at bottom of your plugin.cpp file and all is fine

4:10 PM

the exports

any know how i can change the dino gender? if i do:

c++
if (dino->bIsFemale()()){
  dino->bIsFemale().Set(false);
} else {
  dino->bIsFemale().Set(true);
}

works fine, and i can breed it, but in the dino information dont change, like if i change male to female, the name color is still blue, and in the inventory still says "Male"

Aikar

yeah you have to consider how often is said hook called. then if its super 'hot', be careful what you do in it.

Yes, i do the change, very simple and clear

Loki

You have to multicast the property like this: dino->MulticastProperty(FName("bIsFemale", EFindName::FNAME_Find));

7:24 PM

That way players will get the updated info

7:25 PM

This only works for replicated variables, not all variables will get updated on the client with multicast

thanks

It's possible to add external lib ? (OpenSSL, CURL, etc)

Hatya

It's possible to add external lib ? (OpenSSL, CURL, etc)

why shouldn't it be

Idk, some limitation link to UE or something, but if i correctly understand, i can use all C++ code i want inside plugin ?

you can use any library you want

8:33 PM

API itself uses POCO for requests for example

8:33 PM

it used to use curl

there is a one header library for c++ requests btw

A C++ header-only HTTP/HTTPS server and client library - GitHub - yhirose/cpp-httplib: A C++ header-only HTTP/HTTPS server and client library

@WETBATMAN thx ! I come from .Net dev, some c++ concept are new for me

if I just copy .h file in my project I can use it ?

sure, but if you need to make requests to an https endpoint you need to link with openssl libraries

8:41 PM

you should just use the API requests though

8:42 PM

you can include <Requests.h> after including the API

8:42 PM

API can handle both https and http

I see, i've found request.h in Api Source, but idk how to use it in plugin

are you sending a get request?

Both post and get, and i also want to send file as attachement

8:51 PM

ChatGPT give me this sample : API::Requests::Get()

API::Requests::Get().CreateGetRequest

8:51 PM

first param is the request url

8:52 PM

then you pass it a function which will be called when the request is complete

8:52 PM

and lastly it takes a vector of headers (if any)

8:55 PM

post request is similar but attaching a file won't be very straightforward

im kind of scared that chatgpt got it right to give that API::Requests::Get()

it can get hooks right too

how the hell does it have enough context about this project

open source plugins i guess

Probably, but some response about it's "approximate" and some time it's old (2021 Training data)

I ask it the code for upload file, it's approximative, and not working

one alternative is to write code in another language then invoke a web request or child process to do the stuff like file uploading

9:32 PM

but whys it got to be a file upload, what are you uploading from within ark?

All dino in map, i've get some data (no all) and all dino generate a file of 6MB json payload of 6MB is big it's why i do a file transfer

Hatya

I ask it the code for upload file, it's approximative, and not working

you can't really do that with the built in requests

API::Requests::Get().CreatePostRequest(hookUrl, [](bool success, std::string response) {
                Log::GetLog()->info(response);
                if (success) {
                    Log::GetLog()->info("File upload.");
                }
                else {
                    Log::GetLog()->info("File not upload.");
                }
            }, file_content, "application/octet-stream", { });

9:36 PM

It's the code from ChatGPT

file_content param will expect an std::string not a file

Yes

yeah if you read the file yourself and write the data into a string then it will work

I've try, i receive a Bad Request from Requestbin

"application/octet-stream"

9:39 PM

are you using this type?

9:40 PM

it should be application/json

Yes for pure json, but for trying upload i've change to octet-stream, but not working

Probably i try with local ASPNET Core without upload limit to test

9:57 PM

And when i've launch it i relaunch server to test large request

9:58 PM

pipedream.net has probably 1-2mb limit size

or a firewall is blocking it either one, software caused connection abort im thinking means your local machine though

9:58 PM

but yeah it is typical for default limits to be around 2m

9:58 PM

or 8m for php

I try, i restart server and the url it's localhost

so the api requests is by default threaded yeah?

In my code ? xD

no im asking the arkapi devs

10:06 PM

i wasnt aware that api existed

10:06 PM

but i did wanna look at doing my own discord hooks and yeah dont wanna do that on main thread

Oh, idk, in my code i've just hook on "OnSaveWorld" get all informations and send to API, with ASP API it's work, base limit it's 28Mb in ASP

so that fixed it going to local?

10:07 PM

if so you will have to get config changed on that other host

Yes, local work, but if config it on remote it's work too

10:07 PM

pipedream it's a bin request tester

ah

API Request libs process the request on a worker thread and then calls the callback on the main game thread

Make sens

Hello, I'm trying to give a dino a saddle using the API and it works, but I need to leave the area and come back in order for the saddle to render (or log out and back into the game). I've tried a few things, but nothing seems to work.. Anyone got any ideas? I noticed the ArkShop only gives saddle to dinos that are going into cryopods and not normal ones.. is this a known issue? Thanks in advance!

c++
FString fsaddleBlueprint("Blueprint'/Game/PrimalEarth/CoreBlueprints/Items/Armor/Saddles/PrimalItemArmor_DiplodocusSaddle.PrimalItemArmor_DiplodocusSaddle'");
UClass* saddleClass = UVictoryCore::BPLoadClass(&fsaddleBlueprint); 
UPrimalItem* itemSaddle = dino->GiveSaddle(TSubclassOf<UPrimalItem>(saddleClass), 1, 0, true);
if (itemSaddle)
{
    // none of these worked, i still have to leave the rendered area and come back            
    //itemSaddle->InventoryRefreshCheckItem();
    //itemSaddle->UpdatedItem(false);                
    //dino->MyInventoryComponentField()->InventoryRefresh();                    
    //dino->ForceReplicateNow(false, false);
}

Give the saddle to the dinos inventory then equip it.

I will try that, thank you!

// Now Equip?  but how?

// similiar to AddNewItem when i set to autoequip, this works but i still had to leave and come back for it to render
//_this->MyInventoryComponentField()->ServerEquipItem(&itemSaddle->ItemIDField());

yes i've tried that, it was one of the first things i tried, but i need to log out/ or leave the area to render the saddle

hm been using this for a while in a hook and never had any similar issues

3rd parameter as true doesn't equip it?

Also are you doing this after BeginPlay of the dino?

it does, but only when I log out/in or when i leave the render area

1:29 AM

it magically appears

Lethal

Also are you doing this after BeginPlay of the dino?

yes, I'm doing it on the TameDino hook.. because I wanted to automatically put a generic saddle on a dino after it is tamed (edited)

the code i sent was inside of TameDino and i never had such issues

Post or Pre hook?

post

try TameDino

1:32 AM

or try running force net update on the dino

well son of a

1:38 AM

GiveSaddleFromString and ForceNetUpdate on the dino did the trick.. man I swear i tried that!!!

1:38 AM

Thank you all

1:42 AM

hmm i did get it to work.. I just ran the DoTame command on a dino I already tamed.. but on a fresh dino..it doesnt work(i'm back in the render snafu)... maybe i need a bit of a delay after it is tamed, i'll try that (edited)

yup, after a 1 second delay, it works fine.. ughhh.. it was probably working many times before for me, but I just needed a delay

is it possible to figure out what a dino's level was prior to it being tamed? Minus the taming effectiveness boost? Or how many levels were awarded for taming effectiveness? I searched some of the obvious fields and all come back the current level.

I'm not sure if this is true for all dinos but the after tame level seems to be 150% of the wild level

4:52 PM

So a 100 wild turns to 150 tamed

unless it was attacked while taming right?.. is there a way to get the final taming effectiveness value?

5:17 PM

i couldnt find anything

You could do a sum of all wild points + 1

5:21 PM

I do t know of a field that already has it

hey, any know whats the hook of rex tek saddle fire? I would like search it in the devkit but its 400+gb and I had to uninstall it

@jraServerAPI It's called AbsoluteBaseLevel

7:48 PM

For the level of a dino before tamed

thanks!

I'd like to take the value from RootComponentField()->RelativeRotationField() and rotate it 180 degrees.. Does anyone know how this can be done? Much appreciated!

Get the roll, add 180 and do the modulo with 360

8:09 PM

rotation.Roll = (rotation.Roll + rotateDegrees) % 360 (edited)

Pelayori

Hey now hold on we don’t know what axis they want

Well you got me there

8:32 PM

I sent that as I did that but didn't think about the other axis

Hopefully they don’t just want “180” and have an actual axis in mind

not working

Since stuff like roll, pitch, and yaw change things

jraServerAPI

not working

What axis of rotation do you want

1st.. when i try your code it wont compile

8:33 PM

cast it to int then, it says float is not allowed there

i think roll

Pelayori

cast it to int then, it says float is not allowed there

Well is the .Roll a float?

I want to turn a dino around

substitute

Well is the .Roll a float?

Correct

jraServerAPI

I want to turn a dino around

So what you want is to make the forward direction face the other way?

8:35 PM

Because if so you can’t just use one axis

wait// maybe its the Yaw?

If the Dino is on a sloped surface then their forward direction will have pitch

8:36 PM

As well as yaw

oh man

lol

8:37 PM

You’ll have to get a little involved

8:37 PM

Let me see if I can help

it may not be worth it lol

8:37 PM

haha

FRotator in unreal engine has a series of functions to rotate a vector by x degrees, but when I wanted to use it the api lacks a dozen of functions and data structures to make it work

so i basically have a safezone bubble and i'm preventing pawns from entering.. but if it's a wild dino i was hoping to turn it around first..otherwise it just keeps bopping the bubble over and over and over lol

Maybe this will help

8:40 PM

https://docs.unrealengine.com/4.27/en-US/API/Runtime/Core/Math/FRotator/GetInverse/

FRotator::GetInverse

Returns the inverse of the rotator.

ooh

jraServerAPI

Well you can probably use the yaw for this (edited)

8:40 PM

And just not care about an angle

8:41 PM

I mean just rotate the yaw

8:41 PM

That is

okay

8:43 PM

sooo.. just subtract 180? lol

If you did want to handle pitch roll and yaw you’d have to find the angular distance of each axis between the forwards vector and the backwards vector (negated forward) (edited)

8:44 PM

But you probably don’t need that level of care

8:44 PM

So just 180 on the yaw

ok i will give that a try

substitute

If you did want to handle pitch roll and yaw you’d have to find the angular distance of each axis between the forwards vector and the backwards vector (negated forward) (edited)

But in this case since the diff is 180 if would probably work to negate the rotator

8:46 PM

If you wanted to drop roll (which probably should if you did do all axis as it is not important here) then the manual calculation would be needed

8:47 PM

thank you

Anyways the reason I mention this

8:47 PM

Is pitch yaw and roll are rotations around a fixed axis

8:48 PM

While if you were wanting to rotate around the character’s axis (forward, left, up)

8:48 PM

Things get a little more complicated

substitute

Is pitch yaw and roll are rotations around a fixed axis

(The global forward (+x), left (+z), and up (+y))

the ez method worked

Oh (edited)

8:49 PM

There’s also this

8:49 PM

https://docs.unrealengine.com/5.0/en-US/BlueprintAPI/Math/Vector/RotateVectorAroundAxis/

Rotate Vector Around Axis

just adding 180 to yaw

You can probably use this, use the character up direction and do +180 to yaw (edited)

substitute

https://docs.unrealengine.com/5.0/en-US/BlueprintAPI/Math/Vector/RotateVectorAroundAxis/

Yeah but we are lacking half of the data structures needed internally, and from FRotator / FVector as well

And have everything sorted

I already did extensive testing of those

8:50 PM

We need to include UE4 structures properly

Yes

8:51 PM

@jraServerAPI

8:51 PM

In vect = character rotation to vec3

8:51 PM

Axis = character up vector

8:51 PM

That could work if you take that output back to rotator

8:51 PM

As well

8:55 PM

@jraServerAPI if you are also ever confused on which axis to use for what rotation

8:55 PM

Hold your left arm out

8:55 PM

Either forward, to the left, or up (edited)

8:55 PM

And then rotate it

8:56 PM

How your hand rotates shows which direction (yaw, pitch, or roll) that the rotation applies for the axis (your arm, pointing +x, +y, or +z)

8:56 PM

And then you just match to this if you can’t remember which is which by name (edited)

8:57 PM

You can also see how rotating around an unaligned axis works by doing the same but bending at an angle

How do I modify the Andrewsarchus Saddle to be only crafted in the fabricator?

6:38 PM

Im quite new at this

6:38 PM

I did try to search for anything like modifying items but I dont seem to find much

Items have a RequiresInventoryComponentToCraft array, you add an entry to the fabricator inventory

Mmmmm

6:41 PM

Is there any plugins to look that off?

6:42 PM

I dunno the structure of a plugin so far

Nope, but it should be quite simple if I'm not mistaken

https://github.com/SubstituteR/ArkServerAPI-Template There's a template you can use

You might be able to do that with hooking UWorld::InitializeActorsForPlay, and modify the Class Default Object to reflect that change. Be aware, however that the clients won't see the requirement added but the server will acknowledge that

DECLARE_HOOK(UWorld_InitializeActorsForPlay, void, UWorld*, FString*, bool);
void  Hook_UWorld_InitializeActorsForPlay(UWorld* _this, FString* InURL, bool bResetTime)
{
    static FString AndrewPath("put andrew path here");
    UClass* AndrewClass = UVictoryCore::BPLoadClass(&AndrewPath);

    static FString FabPath("put fabricator inventory path here");
    UClass* FabClass = UVictoryCore::BPLoadClass(&FabPath);

    ((UPrimalItem*)AndrewClass->GetDefaultObject(true))->CraftingRequiresInventoryComponentField().Add(FabClass);
    UWorld_InitializeActorsForPlay_original(_this, InURL, bResetTime);
}

void Load()
{
  ArkApi::GetHooks().SetHook("UWorld.InitializeActorsForPlay", &Hook_UWorld_InitializeActorsForPlay, &UWorld_InitializeActorsForPlay_original);
}

void Unload()
{
  ArkApi::GetHooks().DisableHook("UWorld.InitializeActorsForPlay", &Hook_UWorld_InitializeActorsForPlay);
}

That might be useful, if UWorld::InitializeActorsForPlay is early enough (edited)

Hmmmm

6:55 PM

How would you make the client see the requirements then?

You don't

6:55 PM

Ark api is server side only

6:55 PM

Not everything can be sent back to clients

What would the result of the code?

6:56 PM

Would players would be able to see the andrew's engram in the fabri's inventory?

If it doesn't belong to the fabricator usually, you would need to add is an an engram by yourself

Is there any example out there?

I'm not sure

6:59 PM

You can hook APrimalStructureItemContainer::BeginPlay, and add the item yourself post original call

@Pelayori Im not quite sure where to start to learn about plugins

8:14 PM

Should I look at ark's code?

8:14 PM

Other plugins? (I mean, yeah)

Levviata

Other plugins? (I mean, yeah)

#【💌】ʜᴇʟᴘꜰᴜʟ-ʟɪɴᴋꜱ Has the github with the open source plugins

Ok thanks neat

8:23 PM

My bad for not saying thanks before, I was trying my best to not over-use it and I ended up under-using it

I'm curious, is it possible to control what map is loaded via the API? or is that only from the command line when the server is launched?

might be wrong but i think it's called FString& PGMapNameField() { return GetNativePointerField<FString>(this, "AShooterGameMode.PGMapName"); } that's filled in

Natsu

Thanks.. I wonder at what point or hook, this needs to be implemented.. I'm going to check the GameMode hooks

Jra do you know what hook i need to get to edit dino drop's? was thinking something like ConfigOverrideSupplyCrateItems but i only found LinkedSupplyCrateDestroyed

Dino item drops are generated from template UPrimalInventoryComponent objects. One option is to modify the TArray<FSupplyCrateItemSet> ItemSets field in those UPrimalInventoryComponents. More info here: https://discord.com/channels/513432877904691202/745040653582336120/1092560503882121288 Another option could be to hook when a dino dies and add/remove items from its inventory yourself.

Cannot see that section that you linked

It's in the intermediate discussion channel. Idk how you get access to that

I need some help with TimedRewards, i copied it from ArkShop but for some reason it will crash at the for (auto& reward_data : data->reward_callbacks) When people logout i will remove them from the online_players list. Could someone point me to the right direction ?

Can you post a crashstack

Know what to do
