GLTFState
=========

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

Represents all data of a GLTF file.

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

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

Contains all nodes and resources of a GLTF file. This is used by :ref:`GLTFDocument<class_GLTFDocument>` as data storage, which allows :ref:`GLTFDocument<class_GLTFDocument>` and all :ref:`GLTFDocumentExtension<class_GLTFDocumentExtension>` classes to remain stateless.

GLTFState can be populated by :ref:`GLTFDocument<class_GLTFDocument>` reading a file or by converting a Godot scene. Then the data can either be used to create a Godot scene or save to a GLTF file. The code that converts to/from a Godot scene can be intercepted at arbitrary points by :ref:`GLTFDocumentExtension<class_GLTFDocumentExtension>` classes. This allows for custom data to be stored in the GLTF file or for custom data to be converted to/from Godot nodes.

Method Descriptions

.. rst-class:: classref-method

void **add_used_extension** **(** :ref:`String<class_String>` extension_name, :ref:`bool<class_bool>` required **)**

Appends an extension to the list of extensions used by this GLTF file during serialization. If ``required`` is true, the extension will also be added to the list of required extensions. Do not run this in :ref:`GLTFDocumentExtension._export_post<class_GLTFDocumentExtension_private_method__export_post>`, as that stage is too late to add extensions. The final list is sorted alphabetically.
