WebMar 4, 2015 · First, realize that if the ball is going too horizontal, the dx velocity has already changed - it's too low. In that case, give it a nudge in the x direction. The same is true if the dy velocity is too low - now it's bouncing from side to side and not getting anywhere so give it a nudge in the y direction. Finally, check the overall speed of ...
