.. _class_GLTFMesh_method_get_additional_data:

|
|
|
:ref:`Variant<class_Variant>` **get_additional_data**\ (\ extension_name\: :ref:`StringName<class_StringName>`\ ) :ref:`🔗<class_GLTFMesh_method_get_additional_data>`
|
|
|
|
Gets additional arbitrary data in this **GLTFMesh** instance. This can be used to keep per-node state data in :ref:`GLTFDocumentExtension<class_GLTFDocumentExtension>` classes, which is important because they are stateless.
|
|
|
|
The argument should be the :ref:`GLTFDocumentExtension<class_GLTFDocumentExtension>` name (does not have to match the extension name in the glTF file), and the return value can be anything you set. If nothing was set, the return value is ``null``.

|void| **set_additional_data**\ (\ extension_name\: :ref:`StringName<class_StringName>`, additional_data\: :ref:`Variant<class_Variant>`\ ) :ref:`🔗<class_GLTFMesh_method_set_additional_data>`
|
|
|
|
Sets additional arbitrary data in this **GLTFMesh** instance. This can be used to keep per-node state data in :ref:`GLTFDocumentExtension<class_GLTFDocumentExtension>` classes, which is important because they are stateless.
|
|
|
|
The first argument should be the :ref:`GLTFDocumentExtension<class_GLTFDocumentExtension>` name (does not have to match the extension name in the glTF file), and the second argument can be anything you want.
