Hey, Mike, thanks for the tutorials. I don’t understand some of the conventions used in this tutorial; they seem to go against the Cocoa conventions.

For example, the function: – (Image *) getSubImageAtPoint…

actually creates a retained image and doesn’t autorelease it on returning. Cocoa states that you’re only allowed to do this if your method name starts with init or new or contains the word copy.

secondly, your image class sometimes creates a retained texture2D instance and sometimes doesn’t. I don’t understand why we don’t just retain a passed in texture and have it work one way.

Thanks in advance for your time.

When people find a solution to a problem can they please post what it is instead of just saying they solved it?
