Time for action – spark effects

1. Add the AddSparkEffect() method to the "Public Methods" region of the EffectsManager class:

   public static void AddSparksEffect(
       Vector2 location, 
       Vector2 impactVelocity)
   {
       int particleCount = rand.Next(10, 20);
       for (int x = 0; x < particleCount; x++)
       {
           Particle particle = new Particle(
               location - (impactVelocity / 60),
               Texture,
               ParticleFrame,
               randomDirection((float)rand.Next(10, 20)),
               Vector2.Zero,
               60,
               20,
               Color.Yellow,
               Color.Orange);
           Effects.Add(particle);
       }
   }

2. In the LoadContent() method of the Game1 class, initialize the EffectsManager after the Player class has been initialized:

   EffectsManager.Initialize(
       spriteSheet,
       new Rectangle(0, 288, 2, 2),
       new Rectangle(0, 256, 32, 32),
       3);

3. In the Update() method of the Game1 ...
