title: as3: Box2d how to find nearest bodies
body: <p>How do I find bodies which are located near given body. </p>
  
  <p>About the task. I am trying to detect bodies which are near current. To do it, I've created quite a big collision shape, around the current body, and made it sensor. Collision event was triggered, but it's not what I need. Main thing is that collision event is called only first time when another body entered the detection field... And I want to be able to detect changes in bodies location, after it. (I am considering the fact that other bodies are moving inside detection field)</p>
