Time for action – creating the ScoreZoom class

1. Add a new class file called ScoreZoom.vb to the Flood Control project.

2. Add the following declarations to the ScoreZoom class:

   Public Text As string
   Public DrawColor As Color
   Private displayCounter As Integer
   Private maxDisplayCount As Integer = 30
   Private _scale As Single = 0.4
   Private lastScaleAmount As Single = 0.0
   Private scaleAmount As Single = 0.4

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

   Public ReadOnly Property Scale as Single
       Get
           Return (scaleAmount * displayCounter)
       End Get
   End Property

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

   Public ReadOnly Property IsCompleted as Boolean
       Get
           Return (displayCounter > maxDisplayCount)
       End Get
   End Property

5. Create a constructor for the ScoreZoom class:

   Public Sub New(displayText as String, fontColor as Color)
       Text = displayText
       DrawColor = fontColor
       displayCounter = 0
   End Sub

6. Add an Update() method to the ScoreZoom...
