I've got a bug with my brick breaker style game. The bricks move down one line at a time ever 1.5 seconds. What appears to be happening is occasionally the ball will be just about to hit the brick when the brick moves down a line, and now the ball is behind it. I'm not sure how to fix this. I have two ideas but I'm not sure of implementation. 1 solution would be to check where they were and where they are going to be before rendering the frame. Then if they crossed paths, then register the brick as hit. Solution 2 would be change how the bricks move. I could maybe slide them down line by line, instead of a jump down. I'm not sure of this will fix the issue or not. Any ideas?
