Need help starting an fps
The first thing you need to do is add [_source_] [/_source_] tags (without the underscores) to that code, people dont like code the way youve pasted it, plus it preserves tabs and is syntax highlighted, once you add the source tags people will be more likely to take a look at it
hope that helps

Well, first of all, I may have missed it, but where do you set your viewport? or your projection matrix? the identity matrix isnt going to cut it. First you need to call glViewport() somewhere it should look like glViewport(0, 0, Width, Height); replace Width and Height with whatever the window width and height are for your program, then you need to make sure you have actually set the projection matrix to something useful, the identity matrix isnt all you need, call gluPerspective() should look something like this: gluPerspective(45, Width / Height, 1.0f, 1000.0f) the last two parameters are the near and far plane distances, and the first parameter is half of the fov or field of view, the second parameter is the aspect ratio, simply the width divided by the height
(for the record this is a great reference http://rush3d.com/reference/opengl-bluebook-1.0/
but in all seriousness, it doesnt sount like your very familiar with openGL, get familiar with it before you try and do something like this, even if you had done a simple triangle program you wouldnt have this problem
hope that helps

Thanks i'll get on it. I may have overlooked glveiwport and gluperspective as this is the first program i have made from without copying and pasteing someone else's code and the last language i used set up the window and everything for you.Ill keep trying and maybe eventually ill get it. You lot have been great though.
see ya when i get it together.

Would it be ok if i used nehe's lesson 10 as a base and use different textures and change the map??

if (keys['A']);

this will not work as expected. throw away semicolons from every of your if (keys.. lines

As a basic start, yes! I even recomend that you do so. That's the advantage of having the map on a text file and loading it, instead of hardcoding everything in code! The format nehe uses is very simple, being good for experiment.
The main question that will pop into your mind after a while is how do you change the map without using notepad, i.e having some sort of level editor for it. That's because, for a while, it will be *mighty cool* to have a map loaded from file that you can just change over in notepad and see the changes in your graphic engine. But you'll get bored after a while and want to make more complex examples for your maps and using notepad for it is just out of the question. But i think i'm talking too much... when (and if) that times comes, you'll deal with it. Until you get there, go ahead.

Thanks alot for the encouragment i guess yesterday i wasn't really thinking straight for some reason.
