im no expert on this as i havent even attempted to do it yet but there are things called "reflection vectors" or something. they workout how the "ball" hit the "paddle" and calculate the reflection angle. it might be worth hunting down sparky's collision mod for dark gdk as im pretty sure this stuff is handled very well in that. Hope this helps.

void Void(void){(for i = 0; i < i+1; i++){cout<<"bubzy rules "};}

If your paddle isn't going to be rotating, you can simulate the physics very easily by having a MoveX and a MoveY attribute of your ball, which describe how much it's moving in the x and y direction.

Then when the ball hits a paddle, just multiple MoveY by -1. Or you could multiply it by -1.1 to make the ball speed up each time it hits a paddle ^^.
