Assignment Specifications

You will begin your work on Lab 8 where you left off on Lab 7.

Leave a Trail Behind the Light Cycle

Now, every time you select the key to move the light cycle, a "trail" should be left behind. The trail can be any visual image on the screen (most people will probably select a square).

The reset button should now remove the trails when clicked as well as moving the light cycles back to their original position.

Check for Edges

The game should end when the light cycle reaches the edges of the screen (either light cycle on any of the edges). Implement this functionality. When the game is over, something visible should happen to let the user know that the game is over and that they need to reset to start again.

Check for Other Light Cycles

The game should also end if one light cycle touches the other light cycle. When the game is over, something visible should hapen to let the user know that the game is over and that they need to reset to start again.

Timer Controls Animation

Change the movement of the system so that the movement of the light cycle is controlled by a timer as opposed to the user controlling movement with the keys. This means, every time the timer "goes off" it should tell each light cycle to move.

Before submitting

Make sure that in the comments to your App.java file, there is a comment (in the header comments) about which keys do what in your program. You can integrate this into your GUI if you'd like, but that is not required. What is required is that the information is present in the comments. If there are not comments about which keys control which aspects of game play, you will not receive credit for the parts of the assignments dependent on keys.
