I'm currently writing a small game with box2dweb and I need some direction for this: I'm throwing a Box and have to hit a specific place and trigger an event when the object that's been thrown isn't moving anymore, "fell asleep" so to say.

What's the proper way / best practice for this?

I'm currently thinking of asking the b2World whether an Object is within a specific AABB and then wait a few seconds, check if it's still there and then trigger the event. But this seems to me like the roundabout way and the object might still be moving inside of that AABB and eventually even drop out of the AABB.
