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 – positioning tanks


To position tanks within our game, perform the following steps:

  1. 1. Add the following fields to the declarations area of the TankBattlesGa me class:

    ContentManager p2Content;
    Random rand = new Random();
  2. 2. In the Initialze() method of the TankBattlesGame class, add the following lines right before the call to base.Init ialize():

    p2Content = new ContentManager(this.Services);
    p2Content.RootDirectory = "Content";
  3. 3. Add the StartNewRound() method to the TankBattlesGame class as follows:

    public void StartNewRound()
    {
        tanks.Clear();
    
        Vector3 p1Position = 
            new Vector3(rand.Next(8, 56), 0, rand.Next(8, 56));
        Vector3 p2Position = 
            new Vector3(rand.Next(8, 56), 0, rand.Next(8, 56));
    
        int p1Quadrant = rand.Next(0, 4);
    
        switch (p1Quadrant)
        {
            case 0: 
                p2Position += new Vector3(64, 0, 64);
                break;
    
            case 1: 
                p1Position += new Vector3(64, 0, 0);
                p2Position += new Vector3...
