For a start, it is a bad idea to use a negative number in gluPerspective() for zNear. I find gluPerspective annoying to use personally.

Well I got it too work but I had to use sfml's example, so should I use glFrustrum? BTW, can you help me out with mouse look, like when the mouse is centering it turns your guy.

Well, at the moment, moving the mouse moves the blocks. This is a bad idea. Why not just rotate everything based on the mouse movement? This is a lot faster, and easier to understand.

Well how would I go about this? Would it be like where ever the mouse's x position / y position is the angle of the rotation? I was just moving with the mouse for some tests and it looks like it screwed up my other tests, whoops! Btw I cant seem to figure out glFrustum, I only have gluPerspective working.
