Hi there, I have two questions if I may: 1) I am making a 2d view from top racing game using OpenGL. And I want to put there really big background. Unfortunately it doesn't work on iPhone. So my question is how big texture I can use? 2) This one is related to the first one. Is there any way in Obj-C to determine the size of an object? And how much memory I have used? Thanks. If you need more info, bit of code perhaps, just ask I can provide that. Thank you again.
