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

Groove constraint for 2D physics. This is useful for making a body "slide" through a segment placed in another.

Property Descriptions
---------------------

.. _class_GrooveJoint2D_property_initial_offset:

- :ref:`float<class_float>` **initial_offset**

+-----------+---------------------------+
| *Default* | 25.0                      |
+-----------+---------------------------+
| *Setter*  | set_initial_offset(value) |
+-----------+---------------------------+
| *Getter*  | get_initial_offset()      |
+-----------+---------------------------+

The body B's initial anchor position defined by the joint's origin and a local offset :ref:`initial_offset<class_GrooveJoint2D_property_initial_offset>` along the joint's Y axis (along the groove).

.. _class_GrooveJoint2D_property_length:

- :ref:`float<class_float>` **length**

+-----------+-------------------+
| *Default* | 50.0              |
+-----------+-------------------+
| *Setter*  | set_length(value) |
+-----------+-------------------+
| *Getter*  | get_length()      |
+-----------+-------------------+

The groove's length. The groove is from the joint's origin towards :ref:`length<class_GrooveJoint2D_property_length>` along the joint's local Y axis.
