How I turn this main.cpp into 'Damage and Defence multiplier'?

Hello, dear friends! It's a pleasure to meet you all! I'm new here and I need some help for my learning. My question is about a main.cpp, how to basically run with 'Damage' and 'Defence' multiplier function (with the floating mod). It's possible to use hooking and hex in the same, one enable and the other disabled (to alternate)? Please, if possible can you help me with the code below? Note: The target offsets be like this: The first below is the Damage. // Token: 0x17000D53 RID: 3411 // (get) Token: 0x06003223 RID: 12835 RVA: 0x00010770 File Offset: 0x0000E970 [Token(Token = "0x17000D53")] public int AttackPower { [Token(Token = "0x6003223")] [Address(RVA = "0xDF6200", Offset = "0xDF6200", VA = "0xCCDF6200")] get { return 0; } The second below is Defence: // Token: 0x17000D54 RID: 3412 // (get) Token: 0x06003224 RID: 12836 RVA: 0x00010788 File Offset: 0x0000E988 [Token(Token = "0x17000D54")] public int DefencePower { [Token(Token = "0x6003224")] [Address(RVA = "0xDF6410", Offset = "0xDF6410", VA = "0xCCDF6410")] get { return 0; } } You have all my thanks!!!
