Step 3: Load the X ACT Project through the Content Pipeline
You’ve just created and saved an XACT project that contains two wave files. The next step is to load this XACT
project into the Content Pipeline:> Return to Visual C# 2005 Express Edition, and make sure your game project is loaded. If it isn’t, click Open Project on the File menu, and browse to your project. 
> Right-click on the Content\Audio folder in the Solution Explorer, select Add, and then select Existing Item. Using the dialog box that...

Step 4: Play Sounds Using the Audio API
Access the sounds you wish to play in your game via a Cue object, which you can get by calling GetCue or play
directly by calling PlayCue.In this tutorial, we do both. For our looping engine sound, we call GetCue to get and hold the engine cue, and
pause and resume the cue as our engines turn on and off when the user pulls the trigger. When the player
presses  1to warp, we play the hyperspace sound by calling PlayCue.
Find the UpdateInput method. Modify it to look...

Many things are happening here. Here’s a breakdown of what we’re doing:
//Cue so we can hang on to the sound of the engine
Cue engineSound = null; The Cue represents an instance of a sound. In this case, this Cue represents the sound of our engines when
we pull the right trigger.

}
else if (engineSound.IsPaused)
{ engineSound.Resume();
}
}
else
{ if (engineSound != null && engineSound.IsPlaying)
{engineSound.Pause();
}
}
//in case you get lost, press  Ato warp back to the center...

This code manages the engine sound. Since we enter this code once every frame, we have to make sure we
don’t continually try to play the same sound—we only want to modify the state of the Cue if there’s a change,
such as the trigger being released. This code uses GetCue the first time through the loop to ready the Cue to
play and to play it if the trigger is down. From that point forward, each release of the trigger calls Pause and halts playback of the Cue. Subsequently
pulling the trigger again will...

Congratulations!
At this point, you have a spaceship that floats in 3-D space, that moves around when you use your Xbox 360
Controller, and that makes sounds and gives you feedback in your controller. You have created the very beginnings
of a 3-D game using XNA Game Studio Express, and you’re just getting started. There’s so much more to explore!
