Help! Help with adding coins

[A.Flores]

Hi everyone. In dump.cs, I found this method:

// RVA: 0x16657f8 VA: 0x77a6ad07f8
 public Void AddCoins(Int32 amount, CoinsEarnedMethod earnedMthod, Boolean storeBackup) { }

I tried to hook it using different methods to call it, and it works; coins are added under certain conditions.

But I'm interested in whether it's possible to call such methods in the LGL menu when a switch is pressed in the running game. That is, I want the balance to be increased by, for example, 5000 coins when the button is pressed

How did you hook?

How did you hook?

Something like this:

void (*AddCoins)(void *instance, int amount, int earnedMthod, bool storeBackup);
bool (*_SpendCoins)(void *instance, int amount);
bool SpendCoins(void *instance, int amount) {
    if(instance != NULL) {
    
    AddCoins(instance, 5000, 1, true);
    
    }
    return _SpendCoins(instance, amount);
}

DobbyHook((void *)getAbsoluteAddress("libil2cpp.so", 0x1668ec4), (void *) SpendCoins, (void **) &_SpendCoins);
AddCoins = (void(*)(void *, int, int, bool))getAbsoluteAddress(targetLibName, 0x16657f8);

/*dump.cs:
 // RVA: 0x16657f8 VA: 0x77a6ad07f8
 public Void AddCoins(Int32 amount, CoinsEarnedMethod earnedMthod, Boolean storeBackup) { }
 // RVA: 0x1668ec4 VA: 0x77a6ad3ec4
 public Boolean SpendCoins(Int32 amount) { }
*/

Did you try this?

Compiler Explorer

Compiler Explorer is an interactive online compiler which shows the assembly output of compiled C++, Rust, Go (and many more) code.

godbolt.org

It gives arm instruction, you can probably hex patch hook the parameter
