Time for action – implementing game states

1. Add declarations to the Game1 class for our GameState enum:

   enum GameState { TitleScreen, Playing, PlayerDead, GameOver };
   GameState gameState = GameState.TitleScreen;

2. Still in the declarations section of the Game1 class, add vectors for the display position of our text items, a texture to hold the title screen image, and the delay before respawn when the player dies:

   Vector2 gameOverPosition = new Vector2(350, 300);
   Vector2 livesPosition = new Vector2(600, 580);
   
   Texture2D titleScreen;
   
   float deathTimer = 0.0f;
   float deathDelay = 5.0f;

3. We currently have temporary code in the LoadContent() method that loads straight into the first level of the game. Replace the current LoadContent() method with the following:

   protected override void LoadContent()
   {
       spriteBatch = new SpriteBatch(GraphicsDevice);
   
       TileMap.Initialize(
           Content.Load<Texture2D>(@"Textures\PlatformTiles"));
       TileMap.spriteFont = 
           Content.Load<SpriteFont&gt...
