How can I test sprite collision in cocos2d?

Question

How do I start to implement a class for sprite collision?

Answer 1

As Eric pointed out, CGRectIntersectsRect is the method to test two bounding rects for overlapping. Use the boundingBox method of the CCNode classes to get the correct bounding box for each sprite (or other node).

See my answer here: Collision Detection in Cocos2d game?

Answer 2

I would look into b2ContactListener

You can do some searches on that, and you'll easily get some results
