Help/Support Please help me , How to hook this or patch this game?

[Technology Group007 12 iPhone X 12.4]

I tried patch this game binary file with IDA and HexEditor, but it's looks like a property, I found this class have getter/setter methods. I'm a noob, i don't know how to Hex-Patch a 'double' type or make a THEOS hack.

also I tried use class-dump the game, but how can I hook this method/property with THEOS? thanks😁

I installed my hack on my iPhone but it's not work😑

%hook HeroConfig
- (double)get_attack{

}

OK, I'm done and hack the game attack function. Unity il2cpp parsed game script to C/C++, I need use MSHookFunction to do this.

You could Just use Live offset patcher Which will Make changes why you are using the game      My best way is to llc2ppdump the Unity app and Download dnspy and and drag all the dummydll files into ut and serch for what you want and grab the offset and Use the hex codes
