I am working on a project for a course in college and im having troubles with some coding.
nvm the background tho ...
What im working on is a simple Bricks game.
You have a platform to move about, a ball which bounces of the platform and an array of bricks that you need to destroy with the ball.
The problem is, when the ball hits a brick weird things happen. For example, the ball collides with a brick (the ball should bounce of and the brick should be destroyed), the ball does destroy the brick but also goes through the brick (and sometimes more than just one brick). Another weird thing that is happening upon collision ball-brick is that the brick that the ball collides with ... gets destroyed but so does some other random brick which does not get hit at all.
As well as those two problems ... I have an array set up to be 15x3 bricks/15 columns x 3 rows yet almost half or the array is not displayed.

So many games to code.....so little time.
