SkeletonModification2DPhysicalBones
===================================

**實驗性：** Physical bones may be changed in the future to perform the position update of :ref:`Bone2D<class_Bone2D>` on their own, without needing this resource.

**繼承：** :ref:`SkeletonModification2D<class_SkeletonModification2D>` **<** :ref:`Resource<class_Resource>` **<** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`

將 :ref:`PhysicalBone2D<class_PhysicalBone2D>` 節點的變換套用到 :ref:`Bone2D<class_Bone2D>` 節點的修改器。

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

說明
----

This modification takes the transforms of :ref:`PhysicalBone2D<class_PhysicalBone2D>` nodes and applies them to :ref:`Bone2D<class_Bone2D>` nodes. This allows the :ref:`Bone2D<class_Bone2D>` nodes to react to physics thanks to the linked :ref:`PhysicalBone2D<class_PhysicalBone2D>` nodes.

- |void| **set_physical_bone_chain_length**\ (\ value\: :ref:`int<class_int>`\ )
- :ref:`int<class_int>` **get_physical_bone_chain_length**\ (\ )

在這個修改器中連結的 :ref:`PhysicalBone2D<class_PhysicalBone2D>` 節點的數量。

.. rst-class:: classref-method

|void| **fetch_physical_bones**\ (\ ) :ref:`🔗<class_SkeletonModification2DPhysicalBones_method_fetch_physical_bones>`

清空 :ref:`PhysicalBone2D<class_PhysicalBone2D>` 節點列表，並使用該 :ref:`Skeleton2D<class_Skeleton2D>` 節點的所有 :ref:`PhysicalBone2D<class_PhysicalBone2D>` 子節點填充該列表。

返回位於 ``joint_idx`` 的 :ref:`PhysicalBone2D<class_PhysicalBone2D>` 節點。

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

----

.. _class_SkeletonModification2DPhysicalBones_method_set_physical_bone_node:

.. rst-class:: classref-method

設定位於 ``joint_idx`` 的 :ref:`PhysicalBone2D<class_PhysicalBone2D>` 節點。

\ **注意：**\ 這個索引只適用於這個修改器，不是 :ref:`Skeleton2D<class_Skeleton2D>` 使用的骨骼索引。

.. _class_SkeletonModification2DPhysicalBones_method_start_simulation:

|void| **start_simulation**\ (\ bones\: :ref:`Array<class_Array>`\[:ref:`StringName<class_StringName>`\] = []\ ) :ref:`🔗<class_SkeletonModification2DPhysicalBones_method_start_simulation>`

讓 :ref:`PhysicalBone2D<class_PhysicalBone2D>` 節點開始類比，開始與物理世界進行互動。

還可以把骨骼名稱陣列傳給這個函式，會導致只有這些名稱的 :ref:`PhysicalBone2D<class_PhysicalBone2D>` 節點開始模擬。

----

.. _class_SkeletonModification2DPhysicalBones_method_stop_simulation:

.. rst-class:: classref-method

|void| **stop_simulation**\ (\ bones\: :ref:`Array<class_Array>`\[:ref:`StringName<class_StringName>`\] = []\ ) :ref:`🔗<class_SkeletonModification2DPhysicalBones_method_stop_simulation>`

讓 :ref:`PhysicalBone2D<class_PhysicalBone2D>` 節點停止類比，不再與物理世界進行互動。

還可以把骨骼名稱陣列傳給這個函式，會導致只有這些名稱的 :ref:`PhysicalBone2D<class_PhysicalBone2D>` 節點停止模擬。
