How to create a collidable circle in cocos2d?

Question

I have looked throughout the Internet and other questions on this site, but I can't seem to find the answer. What I want to ask is that is there some sort of simple way that I can create a circle, like a CGRect, and have a collision detection? Do I need something called Box2d to do it? Ive seen it everywhere but have no idea how to use it..

-Thanks

Answer 1

Here are 2 very good tutorials on collision detection. Box2D will simplify your task, because it's all implemented, but there are other ways to do it.
