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) { graphics.GraphicsDevice.Clear(Color.CornflowerBlue); // TODO: Add your drawing code here spriteBatch.Begin(); spriteBatch.Draw(PacMan, PacManLoc, Color.White); spriteBatch.End(); base.Draw(gameTime); }
pacman image is availble here:

the build of the game will look like
Simple 2D texture example with update
HomeWork
