Where do i start

Where do i start to learn, On howto make hacks for this game? E.G. Aimbots,ESP,Unlim.Ammo
I know you can use Cheat Engine for this stuff but eh. too much addresses i just wanna learn the actual programming language used
to make this game and used to make hacks for it.

link to the engin used (i could never find the download): Ken Silverman's Voxlap Page

also, any programing language can be used as long as it can be compiled into a .dll, then a dll injector can be used to put the hack in the game.

I get stuck at the languages in a .dll part, how do you make those hacks? Its not like we have the source code to read and change whatever, how would I change those, and actually make those hacks?
