A tracked object.

An instance of this object represents a device that is tracked, such as a controller or anchor point. HMDs aren't represented here as they are handled internally.

As controllers are turned on and the XRInterface detects them, instances of this object are automatically added to this list of active tracking objects accessible through the XRServer.

The XRController3D and XRAnchor3D both consume objects of this type and should be used in your project. The positional trackers are just under-the-hood objects that make this all work. These are mostly exposed so that GDExtension-based interfaces can interact with them.

 button_pressed button_pressed<>( String name=, name:String=, ):button_pressed

Emitted when a button on this tracker is pressed. Note that many XR runtimes allow other inputs to be mapped to buttons.

 button_released button_released<>( String name=, name:String=, ):button_released

Emitted when a button on this tracker is released.

 input_float_changed input_float_changed<>( String name=, name:String=, float value=, value:float=, ):input_float_changed

Emitted when a trigger or similar input on this tracker changes value.

 input_vector2_changed input_vector2_changed<>( String name=, name:String=, Vector2 vector=, vector:Vector2=, ):input_vector2_changed

Emitted when a thumbstick or thumbpad on this tracker moves.

 pose_changed pose_changed<>( XRPose pose=, pose:XRPose=, ):pose_changed

Emitted when the state of a pose tracked by this tracker changes.

 pose_lost_tracking pose_lost_tracking<>( XRPose pose=, pose:XRPose=, ):pose_lost_tracking

Emitted when a pose tracked by this tracker stops getting updated tracking data.

 profile_changed profile_changed<>( String role=, role:String=, ):profile_changed

Emitted when the profile of our tracker changes.

 Enum TrackerHand<>():Enum

TRACKER_HAND_UNKNOWN = 0

The hand this tracker is held in is unknown or not applicable.


TRACKER_HAND_LEFT = 1

This tracker is the left hand controller.


TRACKER_HAND_RIGHT = 2

This tracker is the right hand controller.

 String description<>():String

The description of this tracker.

 TrackerHand hand<>():TrackerHand

Defines which hand this tracker relates to.

 StringName name<>():StringName

The unique name of this tracker. The trackers that are available differ between various XR runtimes and can often be configured by the user. Godot maintains a number of reserved names that it expects the XRInterface to implement if applicable:

  • left_hand identifies the controller held in the players left hand

  • right_hand identifies the controller held in the players right hand

 String profile<>():String

The profile associated with this tracker, interface dependent but will indicate the type of controller being tracked.

 TrackerType type<>():TrackerType

The type of tracker.

 Variant get_input<>( StringName name=, name:StringName=, ):Variant

Returns an input for this tracker. It can return a boolean, float or Vector2 value depending on whether the input is a button, trigger or thumbstick/thumbpad.

 XRPose get_pose<>( StringName name=, name:StringName=, ):XRPose

Returns the current XRPose state object for the bound name pose.

 bool has_pose<>( StringName name=, name:StringName=, ):bool

Returns true if the tracker is available and is currently tracking the bound name pose.

 void invalidate_pose<>( StringName name=, name:StringName=, ):void

Marks this pose as invalid, we don't clear the last reported state but it allows users to decide if trackers need to be hidden if we lose tracking or just remain at their last known position.

 void set_input<>( StringName name=, name:StringName=, Variant value=, value:Variant=, ):void

Changes the value for the given input. This method is called by a XRInterface implementation and should not be used directly.

 void set_pose<>( StringName name=, name:StringName=, Transform3D transform=, transform:Transform3D=, Vector3 linear_velocity=, linear_velocity:Vector3=, Vector3 angular_velocity=, angular_velocity:Vector3=, TrackingConfidence tracking_confidence=, tracking_confidence:TrackingConfidence=, ):void

Sets the transform, linear velocity, angular velocity and tracking confidence for the given pose. This method is called by a XRInterface implementation and should not be used directly.
