Time for action – adding the ShotManager class

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

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

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

3. Add declarations to the ShotManager class:

   public List<Sprite> Shots = new List<Sprite>();
   private Rectangle screenBounds; 
   
   private static Texture2D Texture;
   private static Rectangle InitialFrame;
   private static int FrameCount;
   private float shotSpeed;
   private static int CollisionRadius;

4. Add a constructor to the the ShotManager class:

   public ShotManager(
       Texture2D texture,
       Rectangle initialFrame,
       int frameCount,
       int collisionRadius,
       float shotSpeed,
       Rectangle screenBounds)
   {
       Texture = texture;
       InitialFrame = initialFrame;
       FrameCount = frameCount;
       CollisionRadius = collisionRadius;
       this.shotSpeed = shotSpeed;
       this.screenBounds = screenBounds;
   }
