@Velociraptor06, I was going to start one, but realized that the scenario was well documented with comments and all that it was not worth starting a new thread. If you have any specific questions about it that are not explained within the documentation, you can start the thread yourself and inform me that you have done so by leaving a comment here.

It appears that something has gone wrong with the program. My ID was -1 and should never change; yet, just today it appears to have changed to -92. Occasionally, also, it will assign the same ID to two persons (which I was sure I coded well enough to prevent from happening). I truly hope that I will not have to remove this scenario from the site (for several reasons). I will filter through the code and see what I can find in the meantime.

If you have an email address, please log on the site and go to http://www.greenfoot.org/scenarios/5719. Start the scenario and browse right to my link and supply me with it. I had made some major changes to the scenario (without changing the main idea). I will send it to you and you can review it to see how I managed to do things (such as adding objects from the world; creating a wall; and, making movement code with obstacles) .

The balls do not always interact with each other properly. They come off at odd angles and sometimes dance with each other before seperating.
