The parent of a hierarchy of :ref:`Bone2D<class_Bone2D>`\ s, used to create a 2D skeletal animation.

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

**Skeleton2D** parents a hierarchy of :ref:`Bone2D<class_Bone2D>` nodes. It holds a reference to each :ref:`Bone2D<class_Bone2D>`'s rest pose and acts as a single point of access to its bones.

To set up different types of inverse kinematics for the given Skeleton2D, a :ref:`SkeletonModificationStack2D<class_SkeletonModificationStack2D>` should be created. The inverse kinematics be applied by increasing :ref:`SkeletonModificationStack2D.modification_count<class_SkeletonModificationStack2D_property_modification_count>` and creating the desired number of modifications.

Signals
-------

.. _class_Skeleton2D_signal_bone_setup_changed:

.. rst-class:: classref-signal

**bone_setup_changed**\ (\ ) :ref:`🔗<class_Skeleton2D_signal_bone_setup_changed>`

Emitted when the :ref:`Bone2D<class_Bone2D>` setup attached to this skeletons changes. This is primarily used internally within the skeleton.

.. rst-class:: classref-section-separator

----

.. rst-class:: classref-descriptions-group

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

.. _class_Skeleton2D_method_execute_modifications:

.. rst-class:: classref-method

|void| **execute_modifications**\ (\ delta\: :ref:`float<class_float>`, execution_mode\: :ref:`int<class_int>`\ ) :ref:`🔗<class_Skeleton2D_method_execute_modifications>`

Executes all the modifications on the :ref:`SkeletonModificationStack2D<class_SkeletonModificationStack2D>`, if the Skeleton2D has one assigned.

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

----

.. _class_Skeleton2D_method_get_bone:

.. rst-class:: classref-method

:ref:`Bone2D<class_Bone2D>` **get_bone**\ (\ idx\: :ref:`int<class_int>`\ ) :ref:`🔗<class_Skeleton2D_method_get_bone>`

Returns a :ref:`Bone2D<class_Bone2D>` from the node hierarchy parented by Skeleton2D. The object to return is identified by the parameter ``idx``. Bones are indexed by descending the node hierarchy from top to bottom, adding the children of each branch before moving to the next sibling.

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

----

.. _class_Skeleton2D_method_get_bone_count:

.. rst-class:: classref-method

:ref:`int<class_int>` **get_bone_count**\ (\ ) |const| :ref:`🔗<class_Skeleton2D_method_get_bone_count>`

Returns the number of :ref:`Bone2D<class_Bone2D>` nodes in the node hierarchy parented by Skeleton2D.

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

----

.. _class_Skeleton2D_method_get_bone_local_pose_override:

.. rst-class:: classref-method

:ref:`Transform2D<class_Transform2D>` **get_bone_local_pose_override**\ (\ bone_idx\: :ref:`int<class_int>`\ ) :ref:`🔗<class_Skeleton2D_method_get_bone_local_pose_override>`

Returns the local pose override transform for ``bone_idx``.

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

----

.. _class_Skeleton2D_method_get_modification_stack:

.. rst-class:: classref-method

:ref:`SkeletonModificationStack2D<class_SkeletonModificationStack2D>` **get_modification_stack**\ (\ ) |const| :ref:`🔗<class_Skeleton2D_method_get_modification_stack>`

Returns the :ref:`SkeletonModificationStack2D<class_SkeletonModificationStack2D>` attached to this skeleton, if one exists.

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

----

.. _class_Skeleton2D_method_get_skeleton:

.. rst-class:: classref-method

:ref:`RID<class_RID>` **get_skeleton**\ (\ ) |const| :ref:`🔗<class_Skeleton2D_method_get_skeleton>`

Returns the :ref:`RID<class_RID>` of a Skeleton2D instance.

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

----

.. _class_Skeleton2D_method_set_bone_local_pose_override:

.. rst-class:: classref-method

|void| **set_bone_local_pose_override**\ (\ bone_idx\: :ref:`int<class_int>`, override_pose\: :ref:`Transform2D<class_Transform2D>`, strength\: :ref:`float<class_float>`, persistent\: :ref:`bool<class_bool>`\ ) :ref:`🔗<class_Skeleton2D_method_set_bone_local_pose_override>`

Sets the local pose transform, ``override_pose``, for the bone at ``bone_idx``.

\ ``strength`` is the interpolation strength that will be used when applying the pose, and ``persistent`` determines if the applied pose will remain.

\ **Note:** The pose transform needs to be a local transform relative to the :ref:`Bone2D<class_Bone2D>` node at ``bone_idx``!

.. _class_Skeleton2D_method_set_modification_stack:

.. rst-class:: classref-method

|void| **set_modification_stack**\ (\ modification_stack\: :ref:`SkeletonModificationStack2D<class_SkeletonModificationStack2D>`\ ) :ref:`🔗<class_Skeleton2D_method_set_modification_stack>`

Sets the :ref:`SkeletonModificationStack2D<class_SkeletonModificationStack2D>` attached to this skeleton.
