There really isn't much 3D in Greenfoot, and there is less documentation. Nccb has a good bit of documentation on 3d, but it might not be quite what you're thinking about.

Oh, all you have to do is right click the scoreboard to reset the highscore. You won't notice the change until you reset the scenario.

@SPower, Sorry, I am still working on that. I forgot that It was like that when I tried to change Erdelf's score. I'm changing that right now. @Erdelf, I am not getting that problem, and apparently SPower isn't either. Try doing it after this update.

@Spower The app does not include texture, but I will consider the idea. @Erdelf, I will add a function where anybody can erase their own highscore. Just wait ten minutes.
