Hello World

Hello World in XNA 3.0 using spritefont. We'll revisit the spritefont when we build the console/debug class

Simple 2D texture demo

Simple xna project that draws a pacman sprite

  • Start a new XNA Project

Add two variable declarations at the top of the class

            Texture2D PacMan;
            Vector2 PacManLoc;

In the LoadContent Function 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

[http://brookfield.rice.iit.edu/jmeyers/gbrowser.php?file=/ITM496-595/ClassSource/Projects/IntroSimpleSpriteWindows/IntroSimpleSpriteWindows/Game1.cs IntroSimpleSpriteWindows/Game1.cs]

the build of the game will look like IntroSimpleSpriteWindows.png

Simple 2D texture example with update


Create an XNA Picture the picture needs to have at least

  • 1 SpriteFont
  • 3 Textures

Make a folder in your pub called XNA. Create an index for this folder and link the zipped VS2008 project here. Also please post a screen shot of your project running.

  • Read Chapter 1 of XNA 3.0
