This could be the base for a 3-D labyrith game. Control the box with the mouse. Don't try to build on this is you don't know a lot about the pen, variables, velocities, or trigonometry - It uses a lot of complicated things. There are a few layering problems, but those can most likely be fixed. I've left the variables showing so you can see how complicated this is: X-1: Used in drawing the board. Y-1: Used in drawing the board. X-2: Used in drawing the board. Y-2: Used in drawing the board. x-vel: The x velocity of the ball. y-vel: The y velocity of the ball. max-y: The maximum y value the ball can be at. min-y: The minimum y value the ball can be at. max-x: The maximum x value the ball can be at. min-x: The minimum x value the ball can be at.
