Overview of this book

Developing games for Windows Phone 7, a new mobile platform, is your big chance to impact the world of mobile games. The XNA 4.0 for Windows Phone 7 integrates a lot of capabilities from software and hardware for you to create incredible games. The next generation of mobile games will be built by you. Windows Phone 7 XNA Cookbook is the best choice for you to make a game on Windows Phone 7. The book helps you to master the indispensable techniques to create your games using XNA 4.0. From the basics such as animating a 2D sprite and interacting with the customized graphical user interface to the more challenging such as 3D graphic rendering and collision detection. This comprehensive cookbook covers all the essential areas of XNA game development for Windows Phone 7, such as approaches to control the sensors, gestures and typical kinds of cameras. We also have recipes for sprite animation, texture rendering, and graphical user interface development that will give you a powerful tool to work with 2D effects. After this we move onto the more juicy stuff with recipes covering 3D graphic rendering and collision detection, and major ways to improve your loading efficiency. You will also work with Xbox live so you can take your game global. Finally, no mobile game development book would be complete without a look at performance optimization to make your games run faster. Windows Phone 7 XNA Cookbook will equip you with the firepower to rock the game world.

Implementing BoundingSphere collision detection in a 3D game

Unlike the bounding box, bounding sphere based collision detection is faster. The technique just needs to compute the length between two points or vertices whether less, equal, or greater than the sum of radii. In modern games, bounding sphere based collision detection is preferred rather than the bounding box. In this recipe, you will learn how to use the technique in an XNA application.

How to do it...

Follow the steps below to master the technique of using BoundingSphere in your game:

1. Create a Windows Phone Game project named BoundingSphereCollision and change Game1.cs to BoundingSphereCollisionGame.cs. Then, create a Content Pipeline Extension Library named MeshVerticesProcessor and replace the ContentProcessor1.cs with MeshVerticesProcessor.cs. After that, add the model file BallLowPoly.FBX to the content project.
2. Define the MeshVerticesProcessor class in MeshVerticesProcessor.cs of the MeshVerticesProcessor project. The...
