Audio.getLoop()

The getLoop() method is a part of the Audio class in the Three.js library that helps to manage audio in the 3D space. This method is used to get the current state of the audio file loop.

Syntax

audio.getLoop();

Return Value

This method returns a Boolean value that represents the current state of the audio file loop.

• true - If the audio file is set to loop.
• false - If the audio file is not set to loop.

Example

const audioLoader = new THREE.AudioLoader();
const listener = new THREE.AudioListener();
const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);

const scene = new THREE.Scene();

audioLoader.load('sound.mp3', function(buffer) {

  const sound = new THREE.Audio(listener);
  sound.setBuffer(buffer);
  sound.setLoop(true);
  sound.setVolume(0.5);
  sound.play();

});

function animate() {

  requestAnimationFrame(animate);

  const loopState = sound.getLoop();

  if(loopState) {
    console.log('Looping is enabled');
  } else {
    console.log('Looping is disabled');
  }

  renderer.render(scene, camera);
}

animate();

In the above example, first, we create an AudioLoader instance to load an audio file called 'sound.mp3'. Next, we create an AudioListener object, a PerspectiveCamera object, and a Scene object.

When the audio file is loaded, we create an Audio object and set its buffer to the audio file buffer using the setBuffer() method. Then, we set the loop property to true using the setLoop() method to enable audio looping. The volume of the audio is set to 0.5 using the setVolume() method. Finally, the audio is played using the play() method.

In the animate() function, we get the loop state of the audio using the getLoop() method of the Audio class. If the loop is enabled, it logs 'Looping is enabled' to the console; otherwise, it logs 'Looping is disabled'.

Conclusion

The Audio.getLoop() method in the Three.js library is used to get the current state of the audio file loop. It returns a Boolean value that represents the current state of the audio file loop. It is a simple yet powerful method that helps in effectively managing audio in your 3D scenes. So, it is a very useful method for the developers who work with the Three.js library.
