Tutorial: How to add and use audio

In order to add a file, use stage.iLoader.addAudio() in the register method:

register() {
    this.iLoader.addAudio("audio_key", "./audio.mp3");
    ...
}

Using AudioInterface:

AudioInterface is a control center for all audio tracks,
default AudioInterface is available via stage.audio,
you could add any other audio interfaces with

this.music = new AudioInterface(this.iLoader);

How to use tracks with AudioInterface

1. first, register the added and loaded audio file in the init, or start method:

stage.audio.registerAudio("audio_key");

2. then get the audio track:

const track = stage.audio.getAudio("audio_key");

3. to play, or pause use:

track.play();
track.pause();

4. In order to loop the audio track, set track.loop parameter to true:

const audioTrack = this.audio.getAudio("audio_key");
audioTrack.loop = true;
audioTrack.play();

5. If you want to take a copy of the track use getAudioCloned():

this.audio.getAudioCloned("audio_key").play();

6. In order to control the volume, set audio.volume from 0 to 1(this will affect only on registered tracks):

this.audio.volume = 0.5;
