Help! Game crashes when hooking Update() method

[Denka]

Hi. When i hook update method the game crashes. Here is my update and old update method:

void (*GoldHack_old)(void *instance);
void GoldHack(void *instance){
    if(instance != NULL && NM.isMajor){
        *(float *) ((uint64_t) instance + 0x300) = 999.5f;
    }
    return GoldHack_old(instance);
}

And here is my hook call: A64HookFunction((void *)getAbsoluteAddress("libil2cpp.so", 0x655D98), (void *)GoldHack, (void **)&GoldHack_old);
Help me pls

void (*old_GoldHack)(void *instance);
void GoldHack(void *instance){
if(instance != NULL && NM.isMajor){
*(float *) ((uint64_t) instance + 0x300) = 999.5f;
}
return old_GoldHack(instance);
}

A64HookFunction((void *)getAbsoluteAddress("libil2cpp.so", 0x655D98), (void *)GoldHack, (void **)&old_GoldHack);

@Poison Modz rename the update old_ / _old doesnt change anything, u can use any random name still works lol

@Denka everything looks fine to me, maybe use other update method from another class that used on that instance

Why are you returning value in à void type ? Void does not return value
Replace this
return GoldHack_old(instance);

By juste
GoldHack_old(instance);

Yes it does h1ve since if you cant understand that void function does not return value you need to start learning programing

You might wanna check that the field offset ( Basically the + 0x300 ) is correct as it could be a null pointer dereference.
