This is a small tip which I’ve encountered twice so far on my current project, and a few times before. The times were far apart enough, that by the time I encountered it again I forgot what the solution was. Just that it was fixible….er somehow.

Introdction Cocos2D is awesome, and it even comes with some amazing templates to create 3 different kinds of projects. Vanilla version, one that combines Box2d(physics engine), and one that combines it with Chipmunk (physics engine).

So as i’ve learned more about programming in Objective-C, things that scared me at first are less scary now. One thing I wondered and stayed away from at first were ‘Structs’ – because they sounded alien to me, I just didn’t get them. In Objective-C, everything inherits from NSObject.
