Setup Project in GSE

Open Visual Studio C# Game Studio Express

Select New Project

Select Windows Game and Create a new folder on a local dirve

Game Studio Express creates the default game files

It should also open the Main Game file game1.cs

<csharp>

1. region Using Statements

using System; using System.Collections.Generic; using Microsoft.Xna.Framework; using Microsoft.Xna.Framework.Audio; using Microsoft.Xna.Framework.Content; using Microsoft.Xna.Framework.Graphics; using Microsoft.Xna.Framework.Input; using Microsoft.Xna.Framework.Storage;

namespace TestGame1 {

   /// <summary>
   /// This is the main type for your game
   /// </summary>
   public class Game1 : Microsoft.Xna.Framework.Game
   {
       GraphicsDeviceManager graphics;
       ContentManager content;

       public Game1()
       {
           graphics = new GraphicsDeviceManager(this);
           content = new ContentManager(Services);
       }

       /// <summary>

       protected override void Initialize()
       {
           // TODO: Add your initialization logic here

           base.Initialize();
       }

       /// <summary>

           {
               // TODO: Load any ResourceManagementMode.Automatic content
           }

           // TODO: Load any ResourceManagementMode.Manual content
       }

       /// <summary>

       /// </summary>
       /// <param name="unloadAllContent">Which type of content to unload.</param>
       protected override void UnloadGraphicsContent(bool unloadAllContent)
       {
           if (unloadAllContent == true)
           {
               content.Unload();
           }
       }

       /// <summary>
       /// Allows the game to run logic such as updating the world,
       /// checking for collisions, gathering input and playing audio.
       /// </summary>
       /// <param name="gameTime">Provides a snapshot of timing values.</param>
       protected override void Update(GameTime gameTime)
       {
           // Allows the default game to exit on Xbox 360 and Windows
           if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed)
               this.Exit();

           // TODO: Add your update logic here

           base.Update(gameTime);
       }

       /// <summary>
       /// This is called when the game should draw itself.
       /// </summary>
       /// <param name="gameTime">Provides a snapshot of timing values.</param>
       protected override void Draw(GameTime gameTime)
       {
           graphics.GraphicsDevice.Clear(Color.CornflowerBlue);

           // TODO: Add your drawing code here

           base.Draw(gameTime);
       }
   }

} </csharp>

All we need to do is to create a folder for the audio. Right click on the project and select 'New Folder' name the folder 'Audio'.

Now copy at least one 44,100 Hz wav file to the folder to use in the test project. You can do this in windows.

Now we can use XACT http://msdn2.microsoft.com/en-us/library/bb174772.aspx

XACT Time

Open XACT

Add a new WaveBank. Wave Banks hold a collection of sound files.

Now create a new Sound Bank. A Sound Bank is a collection of Events, Tracks and Cues.

I like to tile the XACT windows horizontally

Now we can import sound files.

Select Wave Bank and Import Files or right click on the Wave Bank Window and select Import Wave.

Now we have a sound in the Wave Bank we need to add it to the Sound Bank. Drah the sound from the Wave Bank window to the Sound Bank window.

Now that the sound is in the Sound Bank we need to add it as a Cue. Drag the sound from the Sound Bank to the Cue section.

Now you should have the sound in all three sections.

Now we have a sound in the Wave Bank and Sound Bank and a Named Cue we are ready to save our XACT project. Save the project as 'sound1.xap' in the 'Audio' folder that you created in the Game Studio Express Project.

The last step is to build the XACT project to the GSE and integrate it into the game pipeline. Select build from the File menu in XACT.

Import into GSE

Time to Code

Now we need to add the code to the project to play the sound

<csharp> public class Game1 : Microsoft.Xna.Framework.Game

   {
       GraphicsDeviceManager graphics;
       ContentManager content;

       public Game1()
       {
           graphics = new GraphicsDeviceManager(this);
           content = new ContentManager(Services);
       }

</csharp>

add

 //Declare Audio Objects
       public AudioEngine engine;
       public WaveBank wavebank;
       public SoundBank soundbank;

<csharp> public class Game1 : Microsoft.Xna.Framework.Game

   {
       GraphicsDeviceManager graphics;
       ContentManager content;

       //Declare Audio Objects
       public AudioEngine engine;
       public WaveBank wavebank;
       public SoundBank soundbank;

       public Game1()
       {
           graphics = new GraphicsDeviceManager(this);
           content = new ContentManager(Services);

</csharp>

now add to the constructor

//initalize Audio Objects
           engine = new AudioEngine(@"Audio\sound1.xgs");
           wavebank = new WaveBank(engine, @"Audio\Wave Bank.xwb");
           soundbank = new SoundBank(engine, @"Audio\Sound Bank.xsb");

<csharp> public Game1()

       {
           graphics = new GraphicsDeviceManager(this);
           content = new ContentManager(Services);

           //initalize Audio Objects
           engine = new AudioEngine(@"Audio\sound1.xgs");
           wavebank = new WaveBank(engine, @"Audio\Wave Bank.xwb");
           soundbank = new SoundBank(engine, @"Audio\Sound Bank.xsb");
       }

</csharp>

and finally add to the update method

//Play Sound
soundbank.GetCue("FlameWhooshBy").Play();

<csharp> protected override void Update(GameTime gameTime)

       {
           // Allows the default game to exit on Xbox 360 and Windows
           if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed)
               this.Exit();

           // TODO: Add your update logic here

           base.Update(gameTime);

           //Play Sound
           soundbank.GetCue("FlameWhooshBy").Play();
       }

</csharp>

Now you can test you game by running the project (press F5) or
