Time for action – creating the PlayerManager class

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

2. Add declarations to the PlayerManager class:

   Public playerSprite As Sprite
   Private playerSpeed As Single = 160.0
   Private playerAreaLimit As Rectangle
   
   Public PlayerScore As Long = 0
   Public LivesRemaining As Integer = 3
   Public Destroyed As Boolean = false
   
   Private gunOffset As Vector2 = new Vector2(25, 10)
   Private shotTimer As Single = 0.0
   Private minShotTimer As Single = 0.2
   Private playerRadius As Integer = 15
   Public PlayerShotManager As ShotManager

3. Add a constructor to the PlayerManager class:

   Public Sub New (
       Texture As Texture2D,
       initialFrame As Rectangle,
       frameCount As Integer,
       screenBounds As Rectangle)
   
       playerSprite = new Sprite(
           new Vector2(500, 500),
           texture,
           initialFrame,
           Vector2.Zero)
   
       PlayerShotManager = new ShotManager(
           texture,
           new Rectangle(0, 300, 5, 5),
           4,
           2,
      ...
