Figure 7-7. Space Raiders playing sounds from two objects
In canvasApp() , we will create a couple constants that represent the filenames of the
sounds we want to play, but without the associated extension. We will still retrieve the
extension with a call to supportedAudioFormat() , just as we did in the first iteration,
and store that value in the audioType variable.
We will also create an array named sounds that we will use to hold all the HTMLAudio
Element objects we create. This array will tell us how many objects we have created so
we can visually see when all hell breaks loose:
const SOUND_EXPLODE = "explode1";
const SOUND_SHOOT = "shoot1";
var sounds = new Array();
