Time for action – building the GameObject class – part 2

1. Add the updateAnimation() helper method to the GameObject class:

   #region Helper Methods
   private void updateAnimation(GameTime gameTime)
   {
       if (animations.ContainsKey(currentAnimation))
       {
           if (animations[currentAnimation].FinishedPlaying)
           {
              PlayAnimation(animations[currentAnimation].NextAnimation);
           }
           else
           {
              animations[currentAnimation].Update(gameTime);
           }
       }
   }
   #endregion

2. Add a new region called "Public Methods" to the GameObject class:

   #region Public Methods
   #endregion

3. Inside the Public Methods region, add the PlayAnimation() method:

   public void PlayAnimation(string name)
   {
       if (!(name==null) && animations.ContainsKey(name))
       {
           currentAnimation = name;
           animations[name].Play();
       }
   }

4. Still in the Public Methods region, add the Update() method:

   public virtual void Update(GameTime gameTime)
   {
       if (!enabled)
           return;
   
       float...
