If you can edit java code

I need your help.

Basically what I want to know is how to edit this script so that I would never loose. I want the script to everything exactally the same except I want the ball to think that it landed on the oppenents side of the net when it lands on mine.
It is a volleyball game

nevermind. I found another way to beat this game. It took me 6 hours of trial and error editing of the script and countless compiles but I finnaly got it.

Yeah Bro that's a lot of code to go through. :p. But if you say out got it, that's cool. :)
