var pose: StringNameThe name of the pose we’re bound to. Which poses a tracker supports is not known during design time.
var showWhenTracked: BoolEnables showing the node when tracking starts, and hiding the node when tracking is lost.
var tracker: StringNameThe name of the tracker we’re bound to. Which trackers are available is not known during design time.
var trackingChanged: Signal1Emitted when the
trackerstarts or stops receiving updated tracking data for theposebeing tracked. Thetrackingargument indicates whether the tracker is getting updated tracking data.func getHasTrackingData() -> Bool Returns
trueif thetrackerhas current tracking data for theposebeing tracked.func getIsActive() -> Bool Returns
trueif thetrackerhas been registered and theposeis being tracked.func getPose() -> XRPose? Returns the
XRPosecontaining the current state of the pose being tracked. This gives access to additional properties of this pose.func triggerHapticPulse(actionName: String, frequency: Double, amplitude: Double, durationSec: Double, delaySec: Double) Triggers a haptic pulse on a device associated with this interface.
