Time for action – creating the ScoreZoom class

1. Add a new class file called ScoreZoom.cs to the Game1 class.

2. Add the following using directive to the top of the file:

   using Microsoft.Xna.Framework.Graphics;

3. Add the following declarations to the ScoreZoom class:

   public string Text;
   public Color DrawColor;
   private int displayCounter;
   private int maxDisplayCount = 30;
   private float scale = 0.4f;
   private float lastScaleAmount = 0.0f;
   private float scaleAmount = 0.4f;

4. Add the Scale read-only property to the ScoreZoom class:

   public float Scale
   {
       get { return scaleAmount * displayCounter; }
   }

5. Add a Boolean property to indicate when the ScoreZoom has finished displaying:

   public bool IsCompleted
   {
       get { return (displayCounter > maxDisplayCount); }
   }

6. Create a constructor for the ScoreZoom class:

   public ScoreZoom(string displayText, Color fontColor)
   {
       Text = displayText;
       DrawColor = fontColor;
       displayCounter = 0;
   }

7. Add an Update() method to the ScoreZoom class:

   public void Update()
   {
      ...
