Time for action – building a computer terminal

1. Add a new class called ComputerTerminal to the Robot Rampage project.

2. Add declarations to the ComputerTerminal class:

   #Region "Declarations"
   Private _activeSprite As Sprite
   Private _inactiveSprite As Sprite
   Public MapLocation As Vector2
   Public Active As Boolean = True
   Public LastSpawnCounter As Single = 0
   Public MinSpawnTime As Single = 6
   #End Region

3. Add a constructor to the ComputerTerminal class:

   #Region "Constructor"
   Public Sub New(
       activeSprite As Sprite,
       inactiveSprite As Sprite,
       mapLocation As Vector2)
   
       _activeSprite = activeSprite
       _inactiveSprite = inactiveSprite
       Me.MapLocation = mapLocation
   End Sub
   #End Region

4. Add public methods to the ComputerTerminal class:

   #region "Public Methods"
   Public Function IsCircleColliding(
       otherCenter As Vector2, 
       radius As Single) As Boolean
   
       If Not Active Then
           Return False
       End If
   
       Return _activeSprite.IsCircleColliding(otherCenter, radius)
   End Function
   
   Public...
