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 the Maze classes


  1. 1. Add a new class file called Maze.cs to the Cube Chaser project.

  2. 2. Add the following using directives to the top of the Maze.cs class file:

    using Microsoft.Xna.Framework;
    using Microsoft.Xna.Framework.Graphics;
  3. 3. Add the following fields to the Maze class:

    #region Fields
    public const int mazeWidth = 20;
    public const int mazeHeight = 20;
    
    GraphicsDevice device;
    
    VertexBuffer floorBuffer;
    
    Color[] floorColors = new Color[2] { Color.White, Color.Gray };
    #endregion
  4. 4. Add a constructor for the Maze class:

    #region Constructor
    public Maze(GraphicsDevice device)
    {
        this.device = device;
        
        BuildFloorBuffer();
    }#endregion
  5. 5. Add the following region and helper methods to the Maze class:

    #region The Floor
    private void BuildFloorBuffer()
    {
        List<VertexPositionColor> vertexList = 
            new List<VertexPositionColor>();
    
        int counter = 0;
    
        for (int x = 0; x < mazeWidth; x++)
        {
            counter++;
            for (int z = 0...
