BoneAttachment3D
================

**Inherits:** :ref:`Node3D<class_Node3D>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`

А node that dynamically copies or overrides the 3D transform of a bone in its parent :ref:`Skeleton3D<class_Skeleton3D>`.

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

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

This node selects a bone in a :ref:`Skeleton3D<class_Skeleton3D>` and attaches to it. This means that the **BoneAttachment3D** node will either dynamically copy or override the 3D transform of the selected bone.

Property Descriptions
---------------------

.. _class_BoneAttachment3D_property_bone_idx:

.. rst-class:: classref-property

:ref:`int<class_int>` **bone_idx** = ``-1``

.. rst-class:: classref-property-setget

- void **set_bone_idx** **(** :ref:`int<class_int>` value **)**
- :ref:`int<class_int>` **get_bone_idx** **(** **)**

The index of the attached bone.

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

----

.. _class_BoneAttachment3D_property_bone_name:

.. rst-class:: classref-property

:ref:`String<class_String>` **bone_name** = ``""``

.. rst-class:: classref-property-setget

- void **set_bone_name** **(** :ref:`String<class_String>` value **)**
- :ref:`String<class_String>` **get_bone_name** **(** **)**

The name of the attached bone.

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

----

.. _class_BoneAttachment3D_property_override_pose:

.. rst-class:: classref-property

:ref:`bool<class_bool>` **override_pose** = ``false``

.. rst-class:: classref-property-setget

- void **set_override_pose** **(** :ref:`bool<class_bool>` value **)**
- :ref:`bool<class_bool>` **get_override_pose** **(** **)**

Whether the BoneAttachment3D node will override the bone pose of the bone it is attached to. When set to ``true``, the BoneAttachment3D node can change the pose of the bone. When set to ``false``, the BoneAttachment3D will always be set to the bone's transform.

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

.. _class_BoneAttachment3D_method_get_external_skeleton:

.. rst-class:: classref-method

:ref:`NodePath<class_NodePath>` **get_external_skeleton** **(** **)** |const|

Returns the :ref:`NodePath<class_NodePath>` to the external :ref:`Skeleton3D<class_Skeleton3D>` node, if one has been set.

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

----

.. _class_BoneAttachment3D_method_get_use_external_skeleton:

.. rst-class:: classref-method

:ref:`bool<class_bool>` **get_use_external_skeleton** **(** **)** |const|

Returns whether the BoneAttachment3D node is using an external :ref:`Skeleton3D<class_Skeleton3D>` rather than attempting to use its parent node as the :ref:`Skeleton3D<class_Skeleton3D>`.

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

----

.. _class_BoneAttachment3D_method_on_bone_pose_update:

.. rst-class:: classref-method

void **on_bone_pose_update** **(** :ref:`int<class_int>` bone_index **)**

A function that is called automatically when the :ref:`Skeleton3D<class_Skeleton3D>` the BoneAttachment3D node is using has a bone that has changed its pose. This function is where the BoneAttachment3D node updates its position so it is correctly bound when it is *not* set to override the bone pose.

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

----

.. _class_BoneAttachment3D_method_set_external_skeleton:

.. rst-class:: classref-method

void **set_external_skeleton** **(** :ref:`NodePath<class_NodePath>` external_skeleton **)**

Sets the :ref:`NodePath<class_NodePath>` to the external skeleton that the BoneAttachment3D node should use. See :ref:`set_use_external_skeleton<class_BoneAttachment3D_method_set_use_external_skeleton>` to enable the external :ref:`Skeleton3D<class_Skeleton3D>` node.

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

----

.. _class_BoneAttachment3D_method_set_use_external_skeleton:

.. rst-class:: classref-method

void **set_use_external_skeleton** **(** :ref:`bool<class_bool>` use_external_skeleton **)**

Sets whether the BoneAttachment3D node will use an extenral :ref:`Skeleton3D<class_Skeleton3D>` node rather than attenpting to use its parent node as the :ref:`Skeleton3D<class_Skeleton3D>`. When set to ``true``, the BoneAttachment3D node will use the external :ref:`Skeleton3D<class_Skeleton3D>` node set in :ref:`set_external_skeleton<class_BoneAttachment3D_method_set_external_skeleton>`.
