It’s about time I release the engine I created last fall in XNA. This engine is purely academic, and should be treated as such (i.e. don’t go trying to make your own games with it unless you want to retouch most of the engine). However, it’s fully commented, and I believe the code is both an excellent example of something I’ve done in the past, and of how to tackle a ton of different common game programming tasks.

This engine accomplishes many things - input management, 3D-rendering of 2D sprites, animation, text rendering (it was made before the refresh release), Quadtree, Separating Axis Theorem (oh boy!), and of course, object management. It’s not perfect, since I had to code it in a couple weeks so my team could actually do their assignments (see the WSUXNA page for more). However, with as many problems as it tackles, I think the code could be useful to look through for an aspiring game programmer.

Along with the engine code I’ve provided the engine test project I used while developing as a small example of how the engine is used. It’s a bunch of different shapes bouncing around in a box. Each shape also has debug outlines showing the underlying polygon used for collision detection (separating axis theorem allows for any convex polygon to be used!). The bouncing is just based on object centers and current velocities - so it’ll look a little odd. You can switch between objects with up/down (on dpad or keyboard) and rotate them with left/right (dpad or keyboard, again).

Or just the engine demo

Enjoy!
