Time for action - create the HeartBounce Script

We need to attach a new script to the heart. The script will respond to two important situations: when the heart hits the tray, and when the heart misses the tray completely and dive-bombs the Great Beyond. Let's create the script and add some simple code to it.

1. Right-click/secondary-click the Project panel (or use the Create button) and choose Create | JavaScript.
2. Rename the new script HeartBounce.
3. Double-click to open the script in the script editor.
4. Add the following code to the top of the script above the Update function:

   function OnCollisionEnter(col : Collision) {
   if(col.gameObject.tag == "tray") {
   Debug.Log("yes! hit tray!");
   }
   }
