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 – building walls


  1. 1. Add the following to the declarations area of the Maze class:

    VertexBuffer wallBuffer;
    Vector3[] wallPoints = new Vector3[8];
    Color[] wallColors = new Color[4] { 
        Color.Red, Color.Orange, Color.Red, Color.Orange };
  2. 2. Add the following code to the end of the constructor in the Maze class to initialize the w allPoints array and build the walls:

    wallPoints[0] = new Vector3(0, 1, 0);
    wallPoints[1] = new Vector3(0, 1, 1);
    wallPoints[2] = new Vector3(0, 0, 0);
    wallPoints[3] = new Vector3(0, 0, 1);
    wallPoints[4] = new Vector3(1, 1, 0);
    wallPoints[5] = new Vector3(1, 1, 1);
    wallPoints[6] = new Vector3(1, 0, 0);
    wallPoints[7] = new Vector3(1, 0, 1);
    
    BuildWallBuffer();
  3. 3. Add the BuildWallBuffe r() method to the Maze class as follows:

    #region Walls
    private void BuildWallBuffer()
    {
        List<VertexPositionColor> wallVertexList = new List<VertexPositionColor>();
    
        for (int x = 0; x < mazeWidth; x++)
        {
            for (int z = 0; z < mazeHeight...
