<h2>مثال التعليمة البرمجية</h2>
<code>
// create an AudioListener and add it to the camera
const listener = new THREE.AudioListener();
camera.add( listener );
// create the PositionalAudio object (passing in the listener)
const sound = new THREE.PositionalAudio( listener );
// load a sound and set it as the PositionalAudio object's buffer
const audioLoader = new THREE.AudioLoader();
audioLoader.load( 'sounds/song.ogg', function( buffer ) {
sound.setBuffer( buffer );
sound.setRefDistance( 20 );
sound.play();
});
// create an object for the sound to play from
const sphere = new THREE.SphereGeometry( 20, 32, 16 );
const material = new THREE.MeshPhongMaterial( { color: 0xff2200 } );
const mesh = new THREE.Mesh( sphere, material );
scene.add( mesh );
// finally add the sound to the mesh
mesh.add( sound );
