Description
|
|
-----------
|
|
|
|
Abstract base class for all joints in 2D physics. 2D joints bind together two physics bodies (:ref:`node_a<class_Joint2D_property_node_a>` and :ref:`node_b<class_Joint2D_property_node_b>`) and apply a constraint.

- |void| **set_bias**\ (\ value\: :ref:`float<class_float>`\ )
|
|
- :ref:`float<class_float>` **get_bias**\ (\ )
|
|
|
|
When :ref:`node_a<class_Joint2D_property_node_a>` and :ref:`node_b<class_Joint2D_property_node_b>` move in different directions the :ref:`bias<class_Joint2D_property_bias>` controls how fast the joint pulls them back to their original position. The lower the :ref:`bias<class_Joint2D_property_bias>` the more the two bodies can pull on the joint.
|
|
|
|
When set to ``0``, the default value from :ref:`ProjectSettings.physics/2d/solver/default_constraint_bias<class_ProjectSettings_property_physics/2d/solver/default_constraint_bias>` is used.
