Ball deflecting walls like arkanoid or brick game

id like to make a ball deflect and move around a 800,600 screen.

im using sprite candy how can i do a 2d version but for blitz3d +sprite candy , or just blitz3d if you dont have sprite candy

Ahm, I think this is in the wrong forum BMX <-> B3D!

For BMX:
There is a breakout sample that ships with the full version of it.

simply reverse the X, Y speeds when the ball hits something and use a sin/cos calculation when it hits the bat to work out the angle it should bounce off.

Or calculate the cross product between the velocity vector and the collision normal, and use it as the new velocity vector.

Dir=360-Dir works for me if your using direction

@mike, are you sure? A cross product between any two vectors in two dimensional space (which this is) will result in a vector comming out of the page.

oerp, good call, my bad :)
