title: How to move spotlight(s) relative to camera position in Three.js?
body: <p>I wish to have a spotlight that will move together with the camera. the following code works if I only want to keep the spotlight at the same position as the camera at all times:</p>
  
  <pre><code>var pointLight = new THREE.PointLight( 0xffffff, 1, 200 );
  pointLight.position = camera.position;
  scene.add(pointLight);
  </code></pre>
  
  <p>However, how can I make it work so that the spotlight is always <strong>in front of</strong> the camera by a certain distance? Or generally, always in the same position relative to the position of the camera?</p>
