ball dodger: first game

[EatMyBlitch]

Yeah i though so...
Anyways i changed a bit of the idea of the game so now the speed of the killer ball slowly increases as you gather points.
I think i know how to do that so bye im gonna try it now!

[EatMyBlitch]

im trying to make the speed and size of the killer ball change depending on how many points you have. But the code does not work and every time i get 10, 30, 50, 70, 90 the ball flies across the screen and then dissapears. I know whats wrong but i dont know how to fix it. I think that at the scores mentioned above i change the speed and then the ball comes back in the screen but the vx and vy things of the ball cant be changed so it just flies through the wall because it cant stop and change its path because the vx an vy things are fixed and wont change. Somebody please help
