I worked on this project doing most of the input coding (XBox 360 controller & keyboard), some of the game loop & networking, and some of the game play. If you have any questions, I'll try to answer as best as I can remember -- it's been a few weeks since I've worked on it.<p>Elliott's site seems to be down, but our code is open source:<p><a href="http://code.google.com/p/blackthorn-engine-3d/" rel="nofollow">http://code.google.com/p/blackthorn-engine-3d/</a><p>You'll find our project development notes for the class (status reports, some of the initial planning, final report, etc.), along with the code, screen shots from various points in the development, etc.<p>A lot of things are probably still a bit messy there; we only had 10 weeks during the course to hack the engine together. (Although I believe Elliott's been continuing work on generalizing it since the end of the school year.)
