Time for action – adding the ShotManager class

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

2. Add declarations to the ShotManager class:

   Public Shots As List(Of Sprite) = New List(Of Sprite)()
   
   Private Shared _screenBounds As Rectangle
   Private Shared _texture As Texture2D
   Private Shared _initialFrame As Rectangle
   Private Shared _frameCount As Integer
   Private Shared _collisionRadius As Integer
   
   Private _shotSpeed As Single

3. Add a constructor to the the ShotManager class:

   Public Sub New (
       texture As Texture2D,
       initialFrame As Rectangle,
       frameCount As Integer,
       collisionRadius As Integer,
       shotSpeed As Single,
       screenBounds As Rectangle)
   
       _Texture = texture
       _InitialFrame = initialFrame
       _FrameCount = frameCount
       _CollisionRadius = collisionRadius
       _shotSpeed = shotSpeed
       _screenBounds = screenBounds
   End Sub
