This file contains the CheckHitBrick subroutine which determines if the ball is currently hitting a brick, including bouncing the ball, killing the brick, and switching to the next level.

CheckHitBrick

• For all bricks, check if brick is being hit.
• If a brick was hit, call the KillBrick sub routine.
• For the brick being hit, calculate bounce direction and then bounce.

KillBrick

• Set brick presence to false and queue it for drawing.
• If no more present bricks left, load next level.
• Else, increase kill count and dispense a token according to token frequency.
