XRPose
======

**Inherits:** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`

This object contains all data related to a pose on a tracked object.

Description
-----------

XR runtimes often identify multiple locations on devices such as controllers that are spatially tracked.

Orientation, location, linear velocity and angular velocity are all provided for each pose by the XR runtime. This object contains this state of a pose.

Enumerations
------------

.. _enum_XRPose_TrackingConfidence:

.. _class_XRPose_constant_XR_TRACKING_CONFIDENCE_NONE:

.. _class_XRPose_constant_XR_TRACKING_CONFIDENCE_LOW:

.. _class_XRPose_constant_XR_TRACKING_CONFIDENCE_HIGH:

enum **TrackingConfidence**:

- **XR_TRACKING_CONFIDENCE_NONE** = **0** --- No tracking information is available for this pose.

- **XR_TRACKING_CONFIDENCE_LOW** = **1** --- Tracking information may be inaccurate or estimated. For instance with inside out tracking this would indicate a controller may be (partially) obscured.

- **XR_TRACKING_CONFIDENCE_HIGH** = **2** --- Tracking information is deemed accurate and up to date.

Property Descriptions
---------------------

.. _class_XRPose_property_angular_velocity:

- :ref:`Vector3<class_Vector3>` **angular_velocity**

+-----------+-----------------------------+
| *Default* | ``Vector3(0, 0, 0)``        |
+-----------+-----------------------------+
| *Setter*  | set_angular_velocity(value) |
+-----------+-----------------------------+
| *Getter*  | get_angular_velocity()      |
+-----------+-----------------------------+

The angular velocity for this pose.

----

.. _class_XRPose_property_has_tracking_data:

- :ref:`bool<class_bool>` **has_tracking_data**

+-----------+------------------------------+
| *Default* | ``false``                    |
+-----------+------------------------------+
| *Setter*  | set_has_tracking_data(value) |
+-----------+------------------------------+
| *Getter*  | get_has_tracking_data()      |
+-----------+------------------------------+

If ``true`` our tracking data is up to date. If ``false`` we're no longer receiving new tracking data and our state is whatever that last valid state was.

----

.. _class_XRPose_property_linear_velocity:

- :ref:`Vector3<class_Vector3>` **linear_velocity**

+-----------+----------------------------+
| *Default* | ``Vector3(0, 0, 0)``       |
+-----------+----------------------------+
| *Setter*  | set_linear_velocity(value) |
+-----------+----------------------------+
| *Getter*  | get_linear_velocity()      |
+-----------+----------------------------+

The linear velocity of this pose.

----

.. _class_XRPose_property_name:

- :ref:`StringName<class_StringName>` **name**

+-----------+-----------------+
| *Default* | ``&""``         |
+-----------+-----------------+
| *Setter*  | set_name(value) |
+-----------+-----------------+
| *Getter*  | get_name()      |
+-----------+-----------------+

The name of this pose. Pose names are often driven by an action map setup by the user. Godot does suggest a number of pose names that it expects :ref:`XRInterface<class_XRInterface>`\ s to implement:

- ``root`` defines a root location, often used for tracked objects that do not have further nodes.

- ``aim`` defines the tip of a controller with the orientation pointing outwards, for instance: add your raycasts to this.

- ``grip`` defines the location where the user grips the controller

- ``skeleton`` defines the root location a hand mesh should be placed when using hand tracking and the animated skeleton supplied by the XR runtime.

----

.. _class_XRPose_property_tracking_confidence:

- :ref:`TrackingConfidence<enum_XRPose_TrackingConfidence>` **tracking_confidence**

+-----------+--------------------------------+
| *Default* | ``0``                          |
+-----------+--------------------------------+
| *Setter*  | set_tracking_confidence(value) |
+-----------+--------------------------------+
| *Getter*  | get_tracking_confidence()      |
+-----------+--------------------------------+

The tracking confidence for this pose, provides insight on how accurate the spatial positioning of this record is.

----

.. _class_XRPose_property_transform:

- :ref:`Transform3D<class_Transform3D>` **transform**

+-----------+-----------------------------------------------------+
| *Default* | ``Transform3D(1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0)`` |
+-----------+-----------------------------------------------------+
| *Setter*  | set_transform(value)                                |
+-----------+-----------------------------------------------------+
| *Getter*  | get_transform()                                     |
+-----------+-----------------------------------------------------+

The transform containing the original and transform as reported by the XR runtime.

Method Descriptions
-------------------

.. _class_XRPose_method_get_adjusted_transform:

- :ref:`Transform3D<class_Transform3D>` **get_adjusted_transform** **(** **)** |const|

Returns the :ref:`transform<class_XRPose_property_transform>` with world scale and our reference frame applied. This is the transform used to position :ref:`XRNode3D<class_XRNode3D>` objects.

.. |virtual| replace:: :abbr:`virtual (This method should typically be overridden by the user to have any effect.)`
.. |const| replace:: :abbr:`const (This method has no side effects. It doesn't modify any of the instance's member variables.)`
.. |vararg| replace:: :abbr:`vararg (This method accepts any number of arguments after the ones described here.)`
.. |constructor| replace:: :abbr:`constructor (This method is used to construct a type.)`
.. |static| replace:: :abbr:`static (This method doesn't need an instance to be called, so it can be called directly using the class name.)`
.. |operator| replace:: :abbr:`operator (This method describes a valid operator to use with this type as left-hand operand.)`
