Ok so been working on a pong clone while trying to relearn to code after a stroke.
so far i have collision, basic ai(jitters) ball movement BUT it is not smooth
and the ball goes crazy at times any idears on were its going pair shaped?
i created the project in blide so i think it will work standalone but not tested
