nvm, it works fine sorry.
Johnny111111111 (160)
Oh, wait again, I was right it dose not work lol.

I don't really have an answer to your question... I just wanted to point out that you are using a very, very old version of OpenGL. Most of the functions you are using have been deprecated and no longer exist in recent versions.
Johnny111111111 (160)
Actualy they all work great, I have a older version of OpenGL I am guessing. The lighting will not work for some reason.. :/
Disch (13742)
I don't see where you're specifying the position/color/intensity of the lights.
Johnny111111111 (160)
Ah, thats something the tutorial actualy did not mention, ill look that up myself.
Disch (13742)
Whatever tutorial you're using is teaching you outdated techniques. I recommend you find a better one.
Johnny111111111 (160)
Do you know of any better ones?
