well I dont help with giving hacks 4 free but if someone ask how it work ofc I'll answer how much I can but only if I see that you're know what I'm talking about..
Everything made in AutoIt can be made in C++ too but it'll work faster with C++..
+ Multithreading is not supported in AutoIt
AutoIt is good for easy scripts or simple Algorythm but you can always do it with C++ to..So I'd prefer to learn C++ instead of AutoIt if you want to "hack" some games
