PhysicalBone2D
|
||
==============
|
||
|
||
**继承：** :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>`
|
||
|
||
派生自 :ref:`RigidBody2D<class_RigidBody2D>` 的节点，用于让 :ref:`Skeleton2D<class_Skeleton2D>` 中的 :ref:`Bone2D<class_Bone2D>` 对物理作出反应。

描述
|
||
----
|
||
|
||
**PhysicalBone2D** 节点基于 :ref:`RigidBody2D<class_RigidBody2D>`\ ，可以用来使 :ref:`Skeleton2D<class_Skeleton2D>` 中的 :ref:`Bone2D<class_Bone2D>` 节点对物理作出反应。
|
||
|
||
\ **注意：**\ 为了让 :ref:`Bone2D<class_Bone2D>` 节点在视觉上跟随 **PhysicalBone2D** 节点，请在父级 :ref:`Skeleton2D<class_Skeleton2D>` 节点上使用 :ref:`SkeletonModification2DPhysicalBones<class_SkeletonModification2DPhysicalBones>` 修改。
|
||
|
||
\ **注意：**\ **PhysicalBone2D** 节点不会自动创建 :ref:`Joint2D<class_Joint2D>` 节点来让 **PhysicalBone2D** 节点保持在一起。你需要手动创建这些节点。大多数情况下，你想要使用的都是 :ref:`PinJoint2D<class_PinJoint2D>` 节点。创建 **PhysicalBone2D** 子节点后会自动配置 :ref:`Joint2D<class_Joint2D>` 节点。
