It's the end of the semester, and my partner and I spent about 7 hours yesterday finishing up tankwars with about 30 svn commits total, mainly loading tanks and helicopters and allowing them to randomly move and shoot on the map, adding sound effects, and letting the player shoot at the tanks. We had some trouble trying to get the tank pointed at the player, even using the point.angle(point) function, which we never resolved.
If you want to check out the final (unfinished) product, svn co svn.dsource.org/projects/tankwars/trunk/game, and run game.exe. There is a level editor that allows you to place objects and there is a game that allows you to 'play.'
Anyways, unless I get some abundant future free time, this project will most likely be stalled from this point onward, as I'll probably be spending time on my arclib and getting that in better shape.
