I am writing my first iphone app and I am trying to do zoom. Everything was going great and I was using glortho, but then I had a mindblowing issue come up.

The app I am writing has a status bar on the bottom, so when I move or zoom glortho around this status bar is going to move as well.

What is the best way to handle this? Should I have been using glscale?

I'd suggest using a different projection for drawing the status bar than for drawing your game view.

wow you just blew my mind. I never even thought of calling glortho twice. I was literally planning on going back and rewriting the whole program to use scale and call that twice.

You just saved my a lot of time!
