Can Some One Teach How Make Some AA3 Hack

There's no simple hack. It's only simple because someone else made it simple for you. You might want to try hooking D3D however before you go making a wallhack. Before that however you might want to learn what DirectX is, how hooking/detouring works. Before that get familiar with the Windows API, and before you get into windows you might want to learn C++.

I enjoyed Why's post the most

The fact they came running here for a handout rather than learning the obvious prerequisite of knowing C/C++ shows they more than likely wont be taking any of our advice and will simply just go somewhere else looking for a handout.
He'll keep looking in search for a quick hack and probably Googles things like
"Hack maker", "Hack source editor", "Hack source maker". In the end he'll inevitably get fustrated and end with learning nothing at all.
Choobs like these are good for nothings that essentially aren't even hackers or even coders, at heart.

I'm not sure, but I think I've done something like this in the past.
