Is it possible to divide up boundingBox?

In cocos2d, i've got two objects that I want to detect collision with. Im using CGrectintersectsrect, which has been working fine thus far. But I want to divide up the bounding box of one of my objects into 4 quarters, so th开发者_如何学Goat if my object collides in any one of these quarters, appropriate physics can then be applied.

At the moment, there is only 1 large boundingBox which is insufficient. Ideally I would want 4+...

Is this possible, and if so how could i achieve this? If not, is there any other avenue that could work? Thanks everyone, once again :)

The boundingbox method returns a CGRect. You have to divide your rect manualy, there is no pre-made method for that. Otherwise if there is a lot of objects, the best way to detect the collisions is to use Box2d.
