Hello World
Hello World in XNA 4.0 using spritefont. We'll revisit the spriteFont when we build the console/debug class
Hello XNA with texture
Simple xna project that draws a pacman sprite
- Start a new XNA Project
Add two variable declarations at the top of the class <csharp>
Texture2D PacMan; Vector2 PacManLoc;
</csharp>
In the LoadContent
Function add the following code to initialize the two variables declared above
<csharp>
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 //load PacMan image PacMan = Content.Load<texture2d>("pacmanSingle"); //Center PacMan image PacManLoc = new Vector2(graphics.GraphicsDevice.Viewport.Width / 2, graphics.GraphicsDevice.Viewport.Height / 2); }
</csharp>
- Add the following code to the Draw Method to Draw the texture
<csharp> 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); }
</csharp> pacman image is availble here:
the full game1.cs file should look like

the build of the game will look like
Simple 2D texture example with update
HomeWork
Install VS2010 get XNA 4 http://www.microsoft.com/download/en/details.aspx?id=23714
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.
You can take a screen shot using the snip tool. Start run snip in vista or 7. Or you can just press the Print Screen key on the keyboard.
