XNA 4 3D Game Development by Example: Beginner's Guide

By: Kurt Jaegers

Overview of this book

Move beyond the world of flat 2D-based game development and discover how to create your own exciting 3D games with Microsoft XNA 4.0. Create a 3D maze, fire shells at enemy tanks, and drive a rover on the surface of Mars while being attacked by alien saucers."XNA 4 3D Game Development by Example: Beginner's Guide" takes you step-by-step through the creation of three different 3D video games with Microsoft XNA 4.0. Learn by doing as you explore the worlds of 3D graphics and game design.This book takes a step-by-step approach to building 3D games with Microsoft XNA, describing each section of code in depth and explaining the topics and concepts covered in detail. From the basics of a 3D camera system to an introduction to writing DirectX shader code, the games in this book cover a wide variety of both 3D graphics and game design topics. Generate random mazes, load and animate 3D models, create particle-based explosions, and combine 2D and 3D techniques to build a user interface."XNA 4 3D Game Development by Example: Beginner's Guide" will give you the knowledge to bring your own 3D game creations to life.

Preface

Time for action – creating a skybox


To create a skybox for Mars Runner, perform the following steps:

  1. 1. Add a new class file called Skybox.cs to the Mars Runner project.

  2. 2. Add the following using declaration at the beginning of the Skybox class file:

    using Microsoft.Xna.Framework;
    using Microsoft.Xna.Framework.Graphics;
  3. 3. Add fields to the Skybox class as follows:

    #region Fields
    private GraphicsDevice device;
    private Texture2D texture;
    private VertexBuffer cubeVertexBuffer;
    private List<VertexPositionTexture> vertices = new
        List<VertexPositionTexture>();
    private float rotation = 0f;
    #endregion
  4. 4. Create a constructor for the Skybox class as follows:

    #region Constructor
    public Skybox(
        GraphicsDevice graphicsDevice,
        Texture2D texture)
    {
        device = graphicsDevice;
        this.texture = texture;
    
        // Create the cube's vertical faces
        BuildFace(
            new Vector3(0, 0, 0), 
            new Vector3(0, 1, 1), 
            new Vector2(0, 0.25f)); // west face
        BuildFace(
    ...
