==============

**繼承：** :ref:`RigidBody2D<class_RigidBody2D>` **<** :ref:`PhysicsBody2D<class_PhysicsBody2D>` **<** :ref:`CollisionObject2D<class_CollisionObject2D>` **<** :ref:`Node2D<class_Node2D>` **<** :ref:`CanvasItem<class_CanvasItem>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`
|
||
|
||
衍生自 :ref:`RigidBody2D<class_RigidBody2D>` 的節點，用於讓 :ref:`Skeleton2D<class_Skeleton2D>` 中的 :ref:`Bone2D<class_Bone2D>` 對物理作出反應。

說明
|
||
----
|
||
|
||
**PhysicalBone2D** 節點基於 :ref:`RigidBody2D<class_RigidBody2D>`\ ，可以用來使 :ref:`Skeleton2D<class_Skeleton2D>` 中的 :ref:`Bone2D<class_Bone2D>` 節點對物理作出反應。
|
||
|
||
\ **注意：**\ 為了讓 :ref:`Bone2D<class_Bone2D>` 節點在視覺上跟隨 **PhysicalBone2D** 節點，請在父級 :ref:`Skeleton2D<class_Skeleton2D>` 節點上使用 :ref:`SkeletonModification2DPhysicalBones<class_SkeletonModification2DPhysicalBones>` 修改。
|
||
|
||
\ **注意：**\ **PhysicalBone2D** 節點不會自動建立 :ref:`Joint2D<class_Joint2D>` 節點來讓 **PhysicalBone2D** 節點保持在一起。你需要手動建立這些節點。大多數情況下，你想要使用的都是 :ref:`PinJoint2D<class_PinJoint2D>` 節點。建立 **PhysicalBone2D** 子節點後會自動配置 :ref:`Joint2D<class_Joint2D>` 節點。
