# type b2RevoluteJoint

source code

A revolute joint constrains to bodies to share a common point while they are free to rotate about the point. The relative rotation about the shared point is the joint angle. You can limit the relative rotation with a joint limit that specifies a lower and upper angle. You can use a motor to drive the relative rotation about the shared point. A maximum motor torque is provided so that infinite forces are not generated.

### __init__(self, *args) (Constructor) | source code
__init__(self, b2RevoluteJointDef _def) -> b2RevoluteJoint A revolute joint constrains to bodies to share a common point while they are free to rotate about the point. The relative rotation about the shared point is the joint angle. You can limit the relative rotation with a joint limit that specifies a lower and upper angle. You can use a motor to drive the relative rotation about the shared point. A maximum motor torque is provided so that infinite forces are not generated. Overrides: b2Joint.__init__

### __repr__(self) (Representation operator) | source code
Overrides: b2Joint.__repr__

### __getstate__(self, world=None) | source code
