I''ve been following NeHe''s Lesson 10 - loading and moving through a 3D world (http://nehe.gamedev.net/data/lessons/lesson.asp?lesson=10), however, the program does nothing for colliding with walls. I''ve looked over some collision detection explanations, and none of it is really clicking with this particular program. Can anyone help get me started with this problem. Anything would help! Thanks.

There are some tutorials(actually is source code) on that here,
sadly for 3d collision you need some math so there is no easy way you have to figure out your own method to do the collisions.
Good Luck!

OMG! I have just been making a simple 3D maze opengl demo at the moment!


And have just started on collision detection. Because my maze is all on one level, I figure I can do 2D collision detection by looking at the maze from a top-down view.

Of course, this is only delaying the inevitable learning of 3D maths, but it''s a good way to start basic collision detection.
ICQ me if you want to discuss, or here I spose...
