I want to create a simple BreakOut game, so I made a bat, some bricks and a ball. I made the bat and bricks solid, and set the behavior for the ball to 'Ball'. I want a brick to disappear when the ball hits it, but when I set up the event 'On collision between Ball and Brick -> Destroy Brick', it doesn't work properly. The chance a brick disappears is 1/10th or something, seems quite random. When I choose another action, like making the bat disappear, it also doesn't always happen, so the problem seems to be the condition.
So, what did I do wrong, and how to fix it?
