Time for action – beginning the WeaponManager class

1. Add a new class called WeaponManager to the Robot Rampage project.

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

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

3. Modify the declaration of the WeaponManager class to make it a static class:

   static class WeaponManager

4. Add declarations to the WeaponManager class:

   #region declarations
   static public List<Particle> Shots = new List<Particle>();
   static public Texture2D Texture;
   static public Rectangle shotRectangle = 
       new Rectangle(0, 128, 32, 32);
   static public float WeaponSpeed = 600f;
   
   static private float shotTimer = 0f;
   static private float shotMinTimer = 0.15f;
   #endregion

5. Add properties to the WeaponManager class:

   #region Properties
   static public float WeaponFireDelay 
   {
       get 
       { 
           return shotMinTimer;
       }
   }
   
   static public bool CanFireWeapon
   {
       get
       {
           return (shotTimer >= WeaponFireDelay);
       ...
