OpenXRAPIExtension
==================

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

Makes the OpenXR API available for GDExtension.

.. rst-class:: classref-introduction-group

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

**OpenXRAPIExtension** makes OpenXR available for GDExtension. It provides the OpenXR API to GDExtension through the :ref:`get_instance_proc_addr<class_OpenXRAPIExtension_method_get_instance_proc_addr>` method, and the OpenXR instance through :ref:`get_instance<class_OpenXRAPIExtension_method_get_instance>`.

It also provides methods for querying the status of OpenXR initialization, and helper methods for ease of use of the API with GDExtension.
