Adding Sounds

We can add in some sounds to help the game out some. We already have our sound
manager class from Chapter 7, “Sounds and Music,” so we do not need to write any new
code for that. Instead of going through the hassle of creating another XACT project, we
will simply copy the XACT project and sound files from our Chapter 7 Sound Demo
project folder. We should create a Sounds subfolder in our Content folder in our project
to store the files. We only need to have the XACT project included in the project with the
wave files just in the same directory, but not in the solution itself.
We need to declare our sound manager variable and we need to initialize it in our
constructor like all of our other game components:
sound = new SoundManager(this, “Chapter7”);
Components.Add(sound);
Now, we can create our playlist just like we did in the SoundDemo project by adding the
following code to our Initialize method:
string[] playList = { “Song1”, “Song2”, “Song3” };
sound.StartPlayList(playList);
Finally, we should play the explosion sound we set up back in Chapter 7. We should do
this right after we start our explosion when our enemy dies, so we need to add the following
statement at the end of the player.Attacking condition inside of the
CheckForCollisions method:
sound.Play(“explosion”);
Now, we have our songs playing and when we kick a robot we not only see an explosion
but we hear one, too.
