Man, I totally jinxed myself when I predicted that hooking up my RoundLine collision detection / sliding code to my XNA maze game wouldn't be painful. It was. But after a lot of hours of debugging, I've got it working well enough to call done and usable...

I think I've got it! After a couple hours of head-scratching and geometry, my XNA code to handle collision between a disc and a RoundLine is looking correct -- at least in my test app. Soon my maze game will be a bit more challenging, since the walls...

The next thing I want to add to my XNA maze game is collision detection, so my little orange disc can't go right through the maze walls. There seem to be two alternate general approaches that can be taken regarding collision detection: After reading...
