Max Hilbrunner 2ba6d25aa9 Revert "Rename zh_CN/zh_TW to zh_Hans/zh_Hant" 
This reverts commit 57781dc0bc.
The rename, although in line with what we did in the engine, caused problems with RTD we need to fix (or push for a fix) first.

glTF 节点类。
.. rst-class:: classref-introduction-group
描述
----
代表 glTF 节点。glTF 节点中可以包含名称、变换、子节点（glTF 节点）以及其他专门的属性（由各自不同的类表示）。
glTF 节点通常存在于表示 glTF 文件中的所有数据的 :ref:`GLTFState<class_GLTFState>` 内部。大多数 GLTFNode 的属性都是 glTF 文件中其他数据的索引。你可以使用 :ref:`get_additional_data()<class_GLTFNode_method_get_additional_data>` 和 :ref:`set_additional_data()<class_GLTFNode_method_set_additional_data>` 来添加额外的属性，扩展 glTF 节点。

.. rst-class:: classref-property-setget
- |void| **set_visible**\ (\ value\: :ref:`bool<class_bool>`\ )
- :ref:`bool<class_bool>` **get_visible**\ (\ )
如果为 ``true``\ ，则 GLTF 节点可见。如果 ``false``\ ，则 GLTF 节点不可见。这会被转换为 Godot 场景中的 :ref:`Node3D.visible<class_Node3D_property_visible>` 属性，为 ``false`` 时会导出到 ``KHR_node_visibility``\ 。

.. _class_GLTFNode_property_xform:

- :ref:`Transform3D<class_Transform3D>` **get_xform**\ (\ )
glTF 节点相对于其父节点的变换。由于通常首选位置、旋转和缩放属性，因此不使用该属性。

方法说明
--------
.. _class_GLTFNode_method_append_child_index:
.. rst-class:: classref-method
|void| **append_child_index**\ (\ child_index\: :ref:`int<class_int>`\ ) :ref:`🔗<class_GLTFNode_method_append_child_index>`
将给定的子节点索引附加到 :ref:`children<class_GLTFNode_property_children>` 数组。
.. rst-class:: classref-item-separator
----
.. _class_GLTFNode_method_get_additional_data:
.. rst-class:: classref-method
:ref:`Variant<class_Variant>` **get_additional_data**\ (\ extension_name\: :ref:`StringName<class_StringName>`\ ) :ref:`🔗<class_GLTFNode_method_get_additional_data>`
在这个 **GLTFNode** 实例中获取额外的任意数据。这可以用来保持 :ref:`GLTFDocumentExtension<class_GLTFDocumentExtension>` 类中每个节点的状态数据，这很重要，因为它们是无状态的。
参数应该是 :ref:`GLTFDocumentExtension<class_GLTFDocumentExtension>` 的名字（不必与 glTF 文件中的扩展名相匹配），而该返回值可以是你设置的任何值。如果没有设置任何值，则返回值为 ``null``\ 。
.. rst-class:: classref-item-separator
----
.. _class_GLTFNode_method_get_scene_node_path:
.. rst-class:: classref-method
:ref:`NodePath<class_NodePath>` **get_scene_node_path**\ (\ gltf_state\: :ref:`GLTFState<class_GLTFState>`, handle_skeletons\: :ref:`bool<class_bool>` = true\ ) :ref:`🔗<class_GLTFNode_method_get_scene_node_path>`
返回该 GLTF 节点导入后在 Godot 场景树中的 :ref:`NodePath<class_NodePath>`\ 。这在使用 :ref:`GLTFObjectModelProperty<class_GLTFObjectModelProperty>` 导入 glTF 对象模型指针时非常有用，可以处理 ``KHR_animation_pointer``\ 、\ ``KHR_interactivity`` 等扩展。
如果 ``handle_skeletons`` 为 ``true``\ ，则会正确解析骨骼 glTF 节点的路径。例如为 ``false`` 时为 ``^"A/B/C/Bone1/Bone2/Bone3"`` 的路径在为 ``true`` 时会变成 ``^"A/B/C/Skeleton3D:Bone3"``\ 。
.. rst-class:: classref-item-separator

.. _class_GLTFNode_method_set_additional_data:
.. rst-class:: classref-method
|void| **set_additional_data**\ (\ extension_name\: :ref:`StringName<class_StringName>`, additional_data\: :ref:`Variant<class_Variant>`\ ) :ref:`🔗<class_GLTFNode_method_set_additional_data>`
在这个 **GLTFNode** 实例中设置额外的任意数据。这可以用来保持 :ref:`GLTFDocumentExtension<class_GLTFDocumentExtension>` 类中每个节点的状态数据，这很重要，因为它们是无状态的。
第一个参数应该是 :ref:`GLTFDocumentExtension<class_GLTFDocumentExtension>` 的名字（不必与 glTF 文件中的扩展名相匹配），第二个参数可以是任何你想要的东西。
