Discussion error in the code

[Ccb0y]

I'm trying to get instances of a class and it keeps crashing.

#define IL2CPP_MODULE OBFUSCATE("libil2cpp.so")

typedef int64_t (__fastcall* UnityFindObjectOfTypeFunc)(int64_t type);
typedef int64_t (__fastcall* System_Type_GetTypeFunc)(int64_t a1);

UnityFindObjectOfTypeFunc FindObjectOfType =
        reinterpret_cast<UnityFindObjectOfTypeFunc>(reinterpret_cast<char*>(findLibrary("libil2cpp.so")) + 0x15EA128);
System_Type_GetTypeFunc GetTypeFunc =
        reinterpret_cast<System_Type_GetTypeFunc>(reinterpret_cast<char*>(findLibrary("libil2cpp.so")) + 0xDE0D7C);
