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.

.. _class_Skeleton2D_method_execute_modifications:

.. rst-class:: classref-method
|
|
|
|
void **execute_modifications** **(** :ref:`float<class_float>` delta, :ref:`int<class_int>` execution_mode **)**
|
|
|
|
Executes all the modifications on the :ref:`SkeletonModificationStack2D<class_SkeletonModificationStack2D>`, if the Skeleton2D has one assigned.

|
|
|
|
:ref:`Bone2D<class_Bone2D>` **get_bone** **(** :ref:`int<class_int>` idx **)**
|
|
|
|
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.

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

|
:ref:`Transform2D<class_Transform2D>` **get_bone_local_pose_override** **(** :ref:`int<class_int>` bone_idx **)**
|
|
|

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

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