Time for action – building a computer terminal

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

2. Add the following using directives to the top of the class file:

   using Microsoft.Xna.Framework;
   using Microsoft.Xna.Framework.Graphics;

3. Add declarations to the ComputerTerminal class:

   #region Declarations
   private Sprite activeSprite;
   private Sprite inactiveSprite;
   public Vector2 MapLocation;
   public bool Active = true;
   public float LastSpawnCounter = 0;
   public float minSpawnTime = 6.0f;
   #endregion
   

4. Add a constructor to the ComputerTerminal class:

   #region Constructor
   public ComputerTerminal(
       Sprite activeSprite,
       Sprite inactiveSprite,
       Vector2 mapLocation)
   {
       MapLocation = mapLocation;
       this.activeSprite = activeSprite;
       this.inactiveSprite = inactiveSprite;
   }
   #endregion

5. Add public methods to the ComputerTerminal class:

   #region Public Methods
   public bool IsCircleColliding(Vector2 otherCenter, float radius)
   {
       if (!Active)
       {
           return false;
       }
   
     ...
