HingeJoint
==========

**Inherits:** :ref:`Joint<class_Joint>` **<** :ref:`Spatial<class_Spatial>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`

A hinge between two 3D PhysicsBodies.

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

Description
-----------

A HingeJoint normally uses the Z axis of body A as the hinge axis, another axis can be specified when adding it manually though. See also :ref:`Generic6DOFJoint<class_Generic6DOFJoint>`.
