//==============================================================================
// The following example demonstrates how to control audio playback by tapping
// on the screen.
//
// Project setup:
// - Import an audio file (M4A, Mono, 44.1kHz, 16 bit)
// - Create an audio playback controller and set the audio to the imported file
// - Insert a speaker and set the audio to the playback controller
// - Add the Tap Gesture capability to the project under Touch Gestures
//==============================================================================

// Load in the required modules
const Audio = require('Audio');
const TouchGestures = require('TouchGestures');

// Locate the playback controller in the Assets
const playbackController = Audio.getAudioPlaybackController('audioPlaybackController0')

// Play and loop the playback controller
playbackController.setPlaying(true);
playbackController.setLooping(true);

//==============================================================================
// Start and stop the audio by tapping on the screen
//==============================================================================

// Create a boolean to determine if the audio is playing
let isAudioPlaying = true;

// Subscribe to tap gestures on the screen
TouchGestures.onTap().subscribe(function() {
  // Switch the boolean controlling audio playback
  isAudioPlaying = !isAudioPlaying;

  // Start or stop the audio depending on the state of the boolean
  playbackController.setPlaying(isAudioPlaying);
});
