3D Game Development with Microsoft Silverlight 3: Beginner's Guide

By: Gaston C. Hillar

Overview of this book

Microsoft Silverlight is a programmable web browser plug-in that enables the animation, vector graphics, and audio-video playback features that characterize Rich Internet Applications. Silverlight is a great (and growing) RIA platform and games are the next level to exploit in it. But it doesn't offer 3D capabilities out of the box and integrating a 3D engine can involve lot of complex mathematics and matrix algebra. This book will help C# developers to get their fingers on the pulse of 3D in Silverlight. This book uses Balder, an open source 3D engine offering 3D capabilities for Silverlight 3. It leaves out boring matrix algebra and complex 3D mathematics. By the end of the book you will have explored the entire engine, and will be able to design and program your own 3D games with ease! The book begins by introducing you to the fundamental concepts of 2D games and then drives you into the 3D world, using easy-to-follow, step-by-step examples. The book employs amazing graphics and impressive performance, and increasingly adds more features to a 3D game giving you a rich interactive experience. By following the practical examples in this book, you will learn the important concepts, from the creation of the initial models, up to the addition of physics and artificial intelligence. The book helps you to provide realistic behaviors for 3D characters by enveloping models with different textures, using lights to create effects, animating multiple 3D characters using a physics engine (Farseer Physics Engine), and simulating real-life physics. Videos, music, and sounds associated with specific events offer the final touches to the 3D game development learning experience.

Time for action—specializing a game superclass


Now, we can specialize RealTimeGame instead of using subclasses of Game. This requires a small change to the code. We have to override the UpdateWithTime method instead of overriding the Update method. Besides, we have to remove the line base.Update(); used in the Update method. These changes will allow us to animate 3D characters taking into account the elapsed time.

  1. 1. Stay in the 3DInvadersSilverlight project.

  2. 2. Open InvadersGame.cs.

  3. 3. Replace the declaration for the InvadersGame class with this one. (Now, it will be a subclass of RealTimeGame.):

    public class InvadersGame : RealTimeGame
    
  4. 4. Replace the declaration of the Update method with the following. (Now, we override the UpdateWithTime method instead.):

    public override void UpdateWithTime()
    
  5. 5. Remove or comment the following line of code in this method:

    //base.Update();
    
  6. 6. Build and run the solution. The application will run as in the previous examples. You will not notice any changes...
