   I've been programming in cocoa touch for a little while. I've been using isTouchingRect: to detect collisions. I just discovered cocos2d yesterday and plan to use it for my new app. However, I'm not sure what to use for collision detection. I'm using sprites for each character.

   Should I use a for() loop and compare the coordinates of sprites to eachother?
   Should I use the chipmunk framework?
   Is there some command I'm overlooking?

   Thanks- neromid

   It all depends on your application.

   Using Chipmunk only for collision detection perhaps is too much.

   Oh crud. How does I moves it?? (Or delete it?)

   And to your first reply: It's very simple collision detection, just for when a projectile hits an enemy, so I guess Ill just use for loops. Is this method going to be performance taxing?

   Thanks riq!

   Great. Is there anyway to obtain a bounding box/frame of a layer/sprite? All I can see in the documentation is position and scale (not size). I suppose I could create a rectangle using the dimensions of the image I use for each sprite. Nevermind, Ill just do that. Thanks coolman!
