Brief Description
-----------------

Base node for all joint constraints in 2D physics.

Member Variables
----------------

  .. _class_Joint2D_bias:

- :ref:`float<class_float>` **bias** - When :ref:`node_a<class_Joint2D_node_a>` and :ref:`node_b<class_Joint2D_node_b>` move in different directions the ``bias`` controls how fast the joint pulls them back to their original position. The lower the ``bias`` the more the two bodies can pull on the joint. Default value: ``0``

  .. _class_Joint2D_disable_collision:

- :ref:`bool<class_bool>` **disable_collision** - If ``true`` :ref:`node_a<class_Joint2D_node_a>` and :ref:`node_b<class_Joint2D_node_b>` can collide. Default value: ``false``.

  .. _class_Joint2D_node_a:

- :ref:`NodePath<class_nodepath>` **node_a** - The first body attached to the joint. Must derive from :ref:`PhysicsBody2D<class_physicsbody2d>`.

  .. _class_Joint2D_node_b:

- :ref:`NodePath<class_nodepath>` **node_b** - The second body attached to the joint. Must derive from :ref:`PhysicsBody2D<class_physicsbody2d>`.


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

Base node for all joint constraints in 2D physics. Joints take 2 bodies and apply a custom constraint.
