title: Count Collisions in Unity3d
body: <p>So, I have a list of <code>GameObject</code> named boxes, and I need to count collisions of elements from that list in <code>Update()</code>, like:</p>
  
  <pre><code>void Update()
  {
      int collisionNumber = boxes[0].CountCollisions;
  }
  </code></pre>
  
  <p>How can I do that?</p>
