updated version of pong

well...... i fixed some confused things:
1.I don't get update() so I rewrite it.
2.updategameball() have some mistake:
a.mistake with checking if the ball is touching the paddle
b.miatake with checking if the ball hit the wall (should add gameBall.setY(something);) but i didn't fix it. because i have a bloody pre calc test tomorrow.
Also, i changed the action after the ball hit the paddle. Which I add different speed for this...rectangle.

By the way, I'm still using the rectangle as the ball...

I was about to add the other two moving direction for the padle. But i didn't...... because the PRECALCTESTTTTTTTTTTTTTTTT

ahh... I feels like I could fly.......

Anyway. I think if I keep adding more comment then I won't finish my homework

Damn... just realized I still got chem homework to do...

Have a good day
