IL2CPP::Callback::Initialize crashes on UnityEngine.GameObject::GetComponentsInternal call (Unity 6000.0.41f1)

[tikkamasala]

What is the game you are using with IL2CPP Resolver?

Dofus 3 https://www.dofus.com/en/mmorpg/discover

Details:

I am making a bot for this game and I managed to call the functions by putting all my bot logic into the Update hook because calling game functions after IL2CPP::Thread::Attach() made the game crash.

Now that the game has updated from Unity 2022.3.29f1 to Unity 6000.0.41f1, IL2CPP::Callback::Initialize fails. A lot of unity function names have changed and I managed to find the name changes by logging calls to il2cpp_resolve_icall on the game/my own Unity project with the same version. This is what I get :

GameAssembly address: 00007FF937190000

This is the value that got passed to il2cpp_resolve_icall : UnityEngine.GameObject::GetComponentsInternal_Injected(System.IntPtr,System.Type,System.Boolean,System.Boolean,System.Boolean,System.Boolean,System.Object)

The arguments don't seem to have changed

/* 
0 - Object
1 - Type
2 - Use search type as array return type
3 - Recursive
4 - Include inactive
5 - Reverse
6 - Result list
*/
return reinterpret_cast<Unity::il2cppArray<CComponent*>*(UNITY_CALLING_CONVENTION)(void*, void*, bool, bool, bool, bool, void*)>(m_GameObjectFunctions.m_GetComponents)(this, m_pSystemType, false, false, true, false, nullptr);

In Visual Studio Debugger this is the call stack :

 	UnityPlayer.dll!00007ff9513e8c28()	Unknown
 	my.dll!Unity::CGameObject::GetComponents(Unity::il2cppObject * m_pSystemType) Line 61	C++
 	my.dll!Unity::CGameObject::GetComponentByIndex(Unity::il2cppObject * m_pSystemType, unsigned int m_uIndex) Line 73	C++
 	my.dll!Unity::CGameObject::GetComponentByIndex(const char * m_pSystemTypeName, unsigned int m_uIndex) Line 85	C++
 	my.dll!IL2CPP::Helper::GetMonoBehaviour() Line 15	C++
 	my.dll!DebugUnity6000() Line 335	C++

I get an exception for an access violation at 0x000001C6C0000000 on the m_GetComponents call.
m_pSystemType is a class object of System.RuntimeType but I doubt it matters that much.

I am trying to figure out how to fix this but I am looking forward to any idea.

And since the update to Unity6000 cheats are very unstable and always prone to crashes

I just hooked the Update function of a game component that I know is active when the game is running to avoid this problem

[tangosara]

same issue here

[tikkamasala]

I just call IL2CPP::Initialize() and use the lib to retrieve classes/methods/objects at runtime but I mostly use the offsets generated by Il2CppInspector.

As I said I hook the Update function of a GameObject that will virtually always be active using MinHook and I do all my bot's logic from there, I call every game functions from there.

I don't need IL2CPP::Callback::Initialize, which if I'm not mistaken is going to hook a GameObject's function but fails to retrieve a Component with the new Unity API or something.
