b2RevoluteJoint^(native)

A revolute joint constrains two bodies to share a common point while they are free to rotate about the point.

Properties

• enableLimit : Boolean
  Enable / disable joint limits.
• enableMotor : Boolean
  Enable / disable the joint motor.
• lowerLimit : Float
  The lower angle for the joint limit (radians).
• motorSpeed : Float
  The desired motor speed (usually in radians per second)
• motorTorque : Float
  The maximum motor torque, usually in N-m.
• upperLimit : Float
  The upper angle for the joint limit (radians).

Methods

• getLimits() : Multivalue
  Another way to get lower and upper limit.
• setLimits(lower, upper) : b2RevoluteJoint
  Another way to set lower and upper limit

Remarks

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.
