Preface

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...
