Time for action – creating the Enemy class

1. Add a new class called Enemy to the Asteroid Belt Assault project.

2. Add declarations to the Enemy class:

   Public EnemySprite As Sprite
   Public gunOffset As Vector2 = new Vector2(25, 25)
   Private waypoints As Queue(Of Vector2) = New Queue(Of Vector2)()
   Private currentWaypoint As Vector2 = Vector2.Zero
   Private speed As Single = 120
   Public Destroyed As Boolean = False
   Private enemyRadius As Integer = 15
   Private previousLocation As Vector2 = Vector2.Zero

3. Add a constructor to the Enemy class:

   Public Sub New(
       Texture As Texture2D,
       Location As Vector2,
       initialFrame As Rectangle,
       frameCount As Integer)
   
       EnemySprite = new Sprite(
           location, 
           texture, 
           initialFrame, 
           Vector2.Zero)
   
       For x As Integer = 1 to frameCount - 1
           EnemySprite.AddFrame(
               new Rectangle(
               initialFrame.X + (initialFrame.Width * x),
               initialFrame.Y,
               initialFrame.Width,
               initialFrame...
