Building your First Mobile Game using XNA 4.0

By: Brecht Kets, Thomas Goussaert

Overview of this book

With the dawn of the Windows Phone 7 platform, Microsoft has offered us an easy way to create 3D mobile games. In this book, we will build a 3D game for Windows Phone 7 together, taking full advantage of the graphics and touch capabilities, along with the sensors of the platform."Building your First Mobile Game using XNA 4.0" is the book for starting game development on the Windows Phone 7 platform. This book will go over the technical aspects of building games along with designing your own framework. Finally we'll build an actual game together from the ground up! This book will set future mobile game developers in the right direction.The XNA framework empowers us to build 2D and 3D games for PC, Xbox 360 and Windows Phone 7. We will use those capabilities to create stunning 3D games for the Windows Phone 7 platform. We will start by covering the basics like drawing graphics, followed by building a custom framework and end with building a game together!In this book, we will cover drawing 2D and 3D graphics, both static and animations. We will also cover the various ways of handling user input and help set the mood of our game playing both 2D and 3D sound, and accessing the user's media library. The only thing left before building a game is covering several techniques created for making our life easier while building the game, whilst building a framework to do just that. Finally, we'll build a 3D game together that will run on the Windows Phone 7 platform."Building your First Mobile Game using XNA 4.0" is the book you need to get started with mobile game development for Windows Phone 7. Its hands on approach will set you on your way in no time. Let's build some games!

Playing sound


Playing non-positional sounds, being regular sounds, is fairly straight forward. XNA contains a class called SoundEffect. This class can load sounds and play them. Let's jump into a sample.

SoundEffect

The code files contain all the audio samples we need. Add them to your content project. The importer and processor will be automatically detected by XNA Game Studio, depending on the file type. WAV files will use the SoundEffect processor by default, while MP3 files will use the Song processor by default.

Then in the MainGame, we need to create a field that will hold the sound. This field will be of type SoundEffect. Also add a counter of type int. We will play the sound if the counter reaches 100.

SoundEffect jumpSound;
int counter = 0;

In the LoadContent method, we have to load the sound. This is done in the same fashion as loading other content.

jumpSound = Content.Load<SoundEffect>("Jump");

Finally, in the update, we'll increment the counter. If the counter reaches 100, we...
