    some ones been using tutorials at nehe.gamedev.net


    Thats not the problem I have, it just looks like you copied and pasted all the code--i'd be fine it looked like you copied word for word TYPING the code -- or at least made the effort of deleting comments from every line.
    c++->visualc++->directx->opengl->c++;
    (it should be realized my posts are all in a light hearted manner. And should not be taken offense to.)

    Oops my bad, forgot to add the props to NeHe in my code...

    Anyways, Props to NeHe and Anton Snisarenko for giving me quite a bit of help on the collision detection

    Regardless, I made sure I commented on each new line I added to the code so i could look back at what I did

    Don't take that so hard! I think it's awesome what you did, I've never done anything cool with Opengl .

    If you're using DevC++ you should be abke to get it from the webupdate. If not then you should be able to find it on google.
