What is XNA?

Why do we need it?

Why not use c++?

What is DirectX?

show c++ examples

quick start guide - create
How much c# do you know?

in class

Simple 2D texture demo

Simple xna project that draws a pacman sprite

Hello World

make demo


  • Start a new XNA Project

Add two variable declarations at the top of the class

            Texture2D PacMan;
            Vector2 PacManLoc;

In the Load_Content Funtion add the following code to initialize the two variables declared above

        protected override void LoadContent()
            // Create a new SpriteBatch, which can be used to draw textures.
            spriteBatch = new SpriteBatch(GraphicsDevice);

            // TODO: use this.Content to load your game content here
            PacMan = Content.Load<texture2d>("pacmanSingle");
            PacManLoc = new Vector2(graphics.GraphicsDevice.Viewport.Width / 2, graphics.GraphicsDevice.Viewport.Height / 2);
  • Add the following code to the Draw Method to Draw the texture
	protected override void Draw(GameTime gameTime)

            // TODO: Add your drawing code here
            spriteBatch.Draw(PacMan, PacManLoc, Color.White);


pacman image is availble here PacmanSingle.png

the full game1.cs file should look like

[ IntroSimpleSpriteWindows/Game1.cs]

the build of the game will look like IntroSimpleSpriteWindows.png
