thank you so much for doing this learned a lot. Can you maybe do more on this like add moving tiles in the background or show how to update an image like if u move the rocket make it thrust or something.

I followed the tutorial and everything works fine on the simulator.
But when I try to run it on the iPad i get a black screen without textures.
Can you point me in the right direction why it runs on the simulator but not on the device.

alright ive got the image rendered and i figured out how to make it move continuously but i can't get the size right? how do i make it the whole iphone screen size? it stays 80 pixels because of the vertices but how do i change it. Do i make another array?

thanks again for all your help i know you must be busy so i appreciate your response!
