說明
----

Abstract base class for all joints in 3D physics. 3D joints bind together two physics bodies (:ref:`node_a<class_Joint3D_property_node_a>` and :ref:`node_b<class_Joint3D_property_node_b>`) and apply a constraint. If only one body is defined, it is attached to a fixed :ref:`StaticBody3D<class_StaticBody3D>` without collision shapes.

.. _class_Joint3D_property_exclude_nodes_from_collision:

.. rst-class:: classref-property

:ref:`bool<class_bool>` **exclude_nodes_from_collision** = ``true`` :ref:`🔗<class_Joint3D_property_exclude_nodes_from_collision>`

.. rst-class:: classref-property-setget

- |void| **set_exclude_nodes_from_collision**\ (\ value\: :ref:`bool<class_bool>`\ )
- :ref:`bool<class_bool>` **get_exclude_nodes_from_collision**\ (\ )

If ``true``, the two bodies bound together do not collide with each other.

- |void| **set_node_a**\ (\ value\: :ref:`NodePath<class_NodePath>`\ )
- :ref:`NodePath<class_NodePath>` **get_node_a**\ (\ )

Path to the first node (A) attached to the joint. The node must inherit :ref:`PhysicsBody3D<class_PhysicsBody3D>`.

If left empty and :ref:`node_b<class_Joint3D_property_node_b>` is set, the body is attached to a fixed :ref:`StaticBody3D<class_StaticBody3D>` without collision shapes.

- :ref:`NodePath<class_NodePath>` **get_node_b**\ (\ )

Path to the second node (B) attached to the joint. The node must inherit :ref:`PhysicsBody3D<class_PhysicsBody3D>`.

If left empty and :ref:`node_a<class_Joint3D_property_node_a>` is set, the body is attached to a fixed :ref:`StaticBody3D<class_StaticBody3D>` without collision shapes.

- |void| **set_solver_priority**\ (\ value\: :ref:`int<class_int>`\ )
- :ref:`int<class_int>` **get_solver_priority**\ (\ )

用於定義哪個解算器在多個關節中被首先執行的優先順序。數值越低，優先順序越高。
