Learning how to hack

Hi I wanted to learn how to create my own hacks or compile my own hacks from available source code.

I just wanted to know what I should learn to be able to understand the code properly.

From my understanding I need to learn

Action Script 3.0
How to dissasemble and re assemble
What to do when dissasembled (We get .asasm files dont we? ActionScript Assembly?)
anything else?

Also can someone send me a sample script e.g. autoaim so i can work out how people make their scripts
