BoneMap
=======

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

Describes a mapping of bone names for retargeting :ref:`Skeleton3D<class_Skeleton3D>` into common names defined by a :ref:`SkeletonProfile<class_SkeletonProfile>`.

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

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

This class contains a dictionary that uses a list of bone names in :ref:`SkeletonProfile<class_SkeletonProfile>` as key names.

By assigning the actual :ref:`Skeleton3D<class_Skeleton3D>` bone name as the key value, it maps the :ref:`Skeleton3D<class_Skeleton3D>` to the :ref:`SkeletonProfile<class_SkeletonProfile>`.

Signals
-------

.. _class_BoneMap_signal_bone_map_updated:

.. rst-class:: classref-signal

**bone_map_updated** **(** **)**

This signal is emitted when change the key value in the **BoneMap**. This is used to validate mapping and to update **BoneMap** editor.

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

----

.. _class_BoneMap_signal_profile_updated:

.. rst-class:: classref-signal

**profile_updated** **(** **)**

This signal is emitted when change the value in profile or change the reference of profile. This is used to update key names in the **BoneMap** and to redraw the **BoneMap** editor.

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

.. _class_BoneMap_property_profile:

.. rst-class:: classref-property

:ref:`SkeletonProfile<class_SkeletonProfile>` **profile**

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

- void **set_profile** **(** :ref:`SkeletonProfile<class_SkeletonProfile>` value **)**
- :ref:`SkeletonProfile<class_SkeletonProfile>` **get_profile** **(** **)**

A :ref:`SkeletonProfile<class_SkeletonProfile>` of the mapping target. Key names in the **BoneMap** are synchronized with it.

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

.. _class_BoneMap_method_find_profile_bone_name:

.. rst-class:: classref-method

:ref:`StringName<class_StringName>` **find_profile_bone_name** **(** :ref:`StringName<class_StringName>` skeleton_bone_name **)** |const|

Returns a profile bone name having ``skeleton_bone_name``. If not found, an empty :ref:`StringName<class_StringName>` will be returned.

In the retargeting process, the returned bone name is the bone name of the target skeleton.

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

----

.. _class_BoneMap_method_get_skeleton_bone_name:

.. rst-class:: classref-method

:ref:`StringName<class_StringName>` **get_skeleton_bone_name** **(** :ref:`StringName<class_StringName>` profile_bone_name **)** |const|

Returns a skeleton bone name is mapped to ``profile_bone_name``.

In the retargeting process, the returned bone name is the bone name of the source skeleton.

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

----

.. _class_BoneMap_method_set_skeleton_bone_name:

.. rst-class:: classref-method

void **set_skeleton_bone_name** **(** :ref:`StringName<class_StringName>` profile_bone_name, :ref:`StringName<class_StringName>` skeleton_bone_name **)**

Maps a skeleton bone name to ``profile_bone_name``.

In the retargeting process, the setting bone name is the bone name of the source skeleton.
