It only has one player, and no it isn't that technical on the rules of soccer. If the ball gets out of bounds there is no penalty shot, it just respawns randomly on the field. My problem is in my lookatball funtion I think, but I am not sure. Sorry for the long code I am about to post :S

}I already handed this in, I need to figure how to get this to work so that I can work on the last project he asked us to work on. Making this fully work will help me. I mean it feels right, I am telling it to turn untill it turns to face a certain direction by comparing the enum int to an int in while loops, and ask it turn while the enum does not equal that iny vslue. The enum orientationnow has 4 enum value: north, east, south, west. As you can see most of the project is done and it compiles, it just goes into an infinite loop.
