Preface

Time for action – ShotManager-part 1


To manage the shots fired at each other by the tanks, we will add a ShotManager class by performing the following steps:

  1. 1. Add a new class file called ShotManager.cs to the Tank Battles project.

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

    using Microsoft.Xna.Framework;
    using Microsoft.Xna.Framework.Graphics;
  3. 3. Modify the declaration of the class to make it a static class. The class definition line should now read as follows:

    static class ShotManager
  4. 4. Add fields to the Sho tManager class as follows:

    #region Fields
    public static Model ShotModel;
    public static Vector3 Position;
    public static Vector3 Velocity;
    public static Vector3 Gravity = new Vector3(0, -20, 0);
    public static bool ShotActive = false;
    public static bool HitProcessed = true;
    public static Terrain Terrain;
    private static float modelScale = 0.2f;
    #endregion
  5. 5. Add a method to fire shots to the ShotManager class as follows:

    #region Shot Handling
    public static...
