Time for action – keeping track of the bounces

Let's introduce a few more variables to record how many times the player has bounced the heart.

1. Change the code to add these three variables at the top:

   var hitCount:GUIText;
   var numHits:int = 0;
   var hasLost:boolean = false;
   var velocityWasStored = false;
   var storedVelocity : Vector3;

2. Save the script and return to Unity.

3. Select the Heart in the Hierarchy panel.

4. We've created a variable (bucket) to hold a GUIText object. Drag the Bounce Count GUIText GameObject from the Hierarchy panel into the GUIText slot of the heart in the Inspector panel (or choose it from the pop-up menu). Now, whenever we refer to hitCount in our script, we'll be talking about our GUIText GameObject.

5. Add the following code to the Update function:

   function Update() {
     var str:String = "";
   
     if(!hasLost){
       str = numHits.ToString();
     } else {
       str = "Hits:" + numHits.ToString() + "\nYour best:" +
          bestScore;
         
       if(bestScore > lastBest) str += "\nNEW...
