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

.. _class_GLTFDocument_method_append_from_buffer:

.. rst-class:: classref-method

:ref:`Error<enum_@GlobalScope_Error>` **append_from_buffer** **(** :ref:`PackedByteArray<class_PackedByteArray>` bytes, :ref:`String<class_String>` base_path, :ref:`GLTFState<class_GLTFState>` state, :ref:`int<class_int>` flags=0 **)**

Takes a :ref:`PackedByteArray<class_PackedByteArray>` defining a GLTF and imports the data to the given :ref:`GLTFState<class_GLTFState>` object through the ``state`` parameter.

\ **Note:** The ``base_path`` tells :ref:`append_from_buffer<class_GLTFDocument_method_append_from_buffer>` where to find dependencies and can be empty.

.. rst-class:: classref-item-separator

----

.. _class_GLTFDocument_method_append_from_file:

.. rst-class:: classref-method

:ref:`Error<enum_@GlobalScope_Error>` **append_from_file** **(** :ref:`String<class_String>` path, :ref:`GLTFState<class_GLTFState>` state, :ref:`int<class_int>` flags=0, :ref:`String<class_String>` base_path="" **)**

Takes a path to a GLTF file and imports the data at that file path to the given :ref:`GLTFState<class_GLTFState>` object through the ``state`` parameter.

\ **Note:** The ``base_path`` tells :ref:`append_from_file<class_GLTFDocument_method_append_from_file>` where to find dependencies and can be empty.

.. rst-class:: classref-item-separator

----

.. _class_GLTFDocument_method_append_from_scene:

.. rst-class:: classref-method

:ref:`Error<enum_@GlobalScope_Error>` **append_from_scene** **(** :ref:`Node<class_Node>` node, :ref:`GLTFState<class_GLTFState>` state, :ref:`int<class_int>` flags=0 **)**

Takes a Godot Engine scene node and exports it and its descendants to the given :ref:`GLTFState<class_GLTFState>` object through the ``state`` parameter.

.. rst-class:: classref-item-separator

----

.. _class_GLTFDocument_method_generate_buffer:

.. rst-class:: classref-method

:ref:`PackedByteArray<class_PackedByteArray>` **generate_buffer** **(** :ref:`GLTFState<class_GLTFState>` state **)**

Takes a :ref:`GLTFState<class_GLTFState>` object through the ``state`` parameter and returns a GLTF :ref:`PackedByteArray<class_PackedByteArray>`.

.. rst-class:: classref-item-separator

----

.. _class_GLTFDocument_method_generate_scene:

.. rst-class:: classref-method

:ref:`Node<class_Node>` **generate_scene** **(** :ref:`GLTFState<class_GLTFState>` state, :ref:`float<class_float>` bake_fps=30, :ref:`bool<class_bool>` trimming=false, :ref:`bool<class_bool>` remove_immutable_tracks=true **)**

Takes a :ref:`GLTFState<class_GLTFState>` object through the ``state`` parameter and returns a Godot Engine scene node.

.. rst-class:: classref-item-separator

----

.. _class_GLTFDocument_method_register_gltf_document_extension:

.. rst-class:: classref-method

void **register_gltf_document_extension** **(** :ref:`GLTFDocumentExtension<class_GLTFDocumentExtension>` extension, :ref:`bool<class_bool>` first_priority=false **)** |static|

Registers the given :ref:`GLTFDocumentExtension<class_GLTFDocumentExtension>` instance with GLTFDocument. If ``first_priority`` is true, this extension will be run first. Otherwise, it will be run last.

\ **Note:** Like GLTFDocument itself, all GLTFDocumentExtension classes must be stateless in order to function properly. If you need to store data, use the ``set_additional_data`` and ``get_additional_data`` methods in :ref:`GLTFState<class_GLTFState>` or :ref:`GLTFNode<class_GLTFNode>`.

.. rst-class:: classref-item-separator

----

.. _class_GLTFDocument_method_unregister_gltf_document_extension:

.. rst-class:: classref-method

void **unregister_gltf_document_extension** **(** :ref:`GLTFDocumentExtension<class_GLTFDocumentExtension>` extension **)** |static|

Unregisters the given :ref:`GLTFDocumentExtension<class_GLTFDocumentExtension>` instance.

.. rst-class:: classref-item-separator

----

.. _class_GLTFDocument_method_write_to_filesystem:

.. rst-class:: classref-method

:ref:`Error<enum_@GlobalScope_Error>` **write_to_filesystem** **(** :ref:`GLTFState<class_GLTFState>` state, :ref:`String<class_String>` path **)**

Takes a :ref:`GLTFState<class_GLTFState>` object through the ``state`` parameter and writes a glTF file to the filesystem.

\ **Note:** The extension of the glTF file determines if it is a .glb binary file or a .gltf file.
