A-Frame only show vive controls if they exist

Question

Is there a way to only show Vive controllers from A-Frame if they are actually connected. But if not do not show the controllers?

Answer 1

You could write a component to hide the controllers if they aren't found:

AFRAME.registerComponent('hide-if-no-controllers', {
  init: function () {
    if (this.sceneEl.systems['tracked-controls'].controllers.length) { return; }  // Alternatively, use navigator.getGamepads().
    this.setAttribute('visible', false);
  }
});
