As a part of <a href="http://pisa.ucsd.edu/cse125/">CSE 125 at UCSD</a> (a senior design project course in video game), I worked a team with 4 other people to create a 3D multiplayer video game in 10 weeks. The result is Blackthorn 3D, and an accompanying demo game named LKCAS.</div>
<div><br></div><div>The game engine uses cl-opengl (with lispbuilder-sdl) for graphics, and supports particle effects, portals, skinning and animation (with a loader for the <a href="http://www.collada.org/">Collada</a> format). The custom-built, pure-CL physics engine has support for swept sphere collisions against the static environment, allowing us to do things like have the players walk on all the walls in our levels. The network code was written with usocket and userial, and easily supports 4 players over a LAN, or even over the internet (albeit with the latency of your connection). See the following video for an example of what the engine can do:<br clear="all">

I am planning on being the primary maintainer for the engine, and am looking to see whether anyone in the community is interested in helping out. At this point, I am still working on extracting game-specific code from the engine, but I am hoping that the engine will be usable in 3rd-party games by the end of the summer.</div>
