Help! how to hook field offset has no update in lgl mod menu

Sort by date Sort by votes
Correct me if I'm wrong, but you can try this method

Imagine if we have data like this

C#: 
// This class have Update method and CharacterData field
public class CharacterManager
{
    private CharacterData characterData; // 0x68

    // update method
    // RVA: 0x273C3CC Offset: 0x273B3CC VA: 0x273C3CC
    private void Update() { }
}

// This class doesn't have Update method, but this class used in CharacterManager
public class CharacterData
{
    private int characterHealth; // 0x60
}


Now we create Update hook function in our LGL mod menu
C++: 
void (*orig_CharacterUpdate)(void *_this);
void CharacterUpdate(void *_this) {
    if (_this != NULL) {
        // so we can get the CharacterData class from CharacterManager
        // 0x273B3CC is the offset of Update method from CharacterManager
        // 0x68 is the offset of CharacterData class from CharacterManager
        // 0x60 is the offset of Health from CharacterData class
        // so 0x273B3CC + 0x68 + 0x60 = characterHealth
        *(int *) ((uint64_t) _this + 0x68 + 0x60) = 9999999; // you can set the health value here
        
    }
}

After that, we can use that hook with dobby or another hooking library
C++: 
DobbyHook((void *) getAbsoluteAddress("libil2cpp.so",0x273B3CC), (void *) &CharacterUpdate, (void **) &orig_CharacterUpdate);

Start by finding references to the class that has no update. Find a class that has a pointer leading to that class. Once you find it, make some hooks for it.

or

You can use FindObjectOfType, it is a method in Unity Engine class within the dumps. Search for it, once searched, you need to create a hook for it. Find the object of the class that doesn't have update. Call those methods and hooks within a random class that has update. (Wouldn't recommend, but go ahead).
