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 the Tank class


We can build the Tank class using the following steps:

  1. 1. Add a new class file called Tank.cs to the Tank Battles project.

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

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

    #region Fields
    private Model model;
    private GraphicsDevice device;
            
    private Vector3 position;
    private float tankRotation;
    private float turretRotation;
    private float gunElevation;
    
    private Matrix baseTurretTransform;
    private Matrix baseGunTransform;
    private Matrix[] boneTransforms;
    #endregion
  4. 4. Add the following properties to the Tank class:

    #region Properties
    public Vector3 Position
    {
        get
        {
            return position;
        }
        set
        {    
            position = value;
        }
    }
    
    public float TankRotation
    {
        get
        {
            return tankRotation;
        }
        set
        {
            tankRotation = MathHelper.WrapAngle(value);
        }
    ...
