I am thinking about doing my ball physics and collision detection for pong as follows. I would have a xvec and yvec (direction) vector which would work like this. The starting velocity of a ball would be x=-1, and y=1 (after making the prototype work, I would probably make the start of the game set these values with a random seed/number). So, using the cartestian coordinate system, I would loop it like this and expect to move the ball like this: Would the basic collision stuff check and work out correctly? (pseudocode)

if(y-3>screenHeightMin && y+3paddleFront && x+3

Uhh, yeah, that''d work pretty well I think...I don''t see why you couldn''t just try something this simple and see for yourself.

Your pseudo-code did not come through correctly.

Anonymous Poster, How so?
