Time for action – the ShotManager class

To manage how the shots will function in the world, perform the following steps:

1. 1. Add a new class file called ShotManager.cs to the Mars Runner project.

2. 2. Add the following using directives at the beginning of the ShotManager class file:

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

3. 3. Add fields to the ShotManager class as follows:

   #region Fields
   List<PlayerShot> playerShots = new List<PlayerShot>();
   List<EnemyShot> enemyShots = new List<EnemyShot>();
   Model shotModel;
   GraphicsDevice device;
   #endregion

4. 4. Add a constructor to the ShotManager class as follows:

   #region Constructor
   public ShotManager(GraphicsDevice device, Model model)
   {
       shotModel = model;
       this.device = device;         
   }
   #endregion

5. 5. Add the Helper Methods region to the ShotManager class, which contains methods to add shots to the shot lists as follows:

   #region Helper Methods
   public void AddPlayerShot(Vector3 position)
   {
       bool...
