The tracked-controls component interfaces with tracked controllers. tracked-controls uses the Gamepad API to handle tracked controllers, and is abstracted by the hand-controls componentas well as the vive-controlsand oculus-touch-controlscomponents. This component elects the appropriate controller, applies pose to the entity, observes buttons state and emits appropriate events.

Example

Note that due to recent browser-specific changes, Vive controllers may be returned by the Gamepad API with id values of either “OpenVR Gamepad” or “OpenVR Controller”, so using idPrefix for Vive / OpenVR controllers is recommended.

            
              <
                a-entity
                tracked-controls=
                "controller: 0; idPrefix: OpenVR">
              </
                a-entity>
