I tested it (I don't know why :) ), and if I said spin() and right(), the character will always be stuck at the right side of the world. I give you this tip: Instead of this code for right: [code]public void right() { setLocation(getX() + 5, getY()); }[/code] use this: [code]public void right() { move(5); }[/code] And do this for left(): [code] public void right() { move(-5); }[/code] I hope this helps. If you want, you can checkout my scenario Libary, which is basically a scenario with some great APIs. You can use that in this scenario if you want so.
