能够修改 Skeleton3D 中骨骼的节点。
.. rst-class:: classref-introduction-group
描述
----
**SkeletonModifier3D** 会将父级 :ref:`Skeleton3D<class_Skeleton3D>` 节点作为目标 :ref:`Skeleton3D<class_Skeleton3D>`\ 。
如果存在 :ref:`AnimationMixer<class_AnimationMixer>`\ ，则修改会在 :ref:`AnimationMixer<class_AnimationMixer>` 的播放处理后执行。
该节点应该用于实现自定义 IK 解算器、约束、骨架物理。

覆盖该虚方法可以实现自定义骨架修改器。你应该在这里执行获取 :ref:`Skeleton3D<class_Skeleton3D>` 的当前姿势、应用姿势之类的操作。
\ :ref:`_process_modification()<class_SkeletonModifier3D_private_method__process_modification>` 不得将 :ref:`influence<class_SkeletonModifier3D_property_influence>` 应用于骨骼姿势，因为 :ref:`Skeleton3D<class_Skeleton3D>` 会自动将影响应用于修改器设置的所有骨骼姿势。
