Urho.Urho2D.ConstraintRevolute2D Class

2D revolute constraint component.

See Also: ConstraintRevolute2D


public class ConstraintRevolute2D : Constraint2D


This constraint forces two bodies to share a common hinge anchor point ConstraintRevolute2D.Anchor

You can control the relative rotation of the two bodies (the constraint angle) using a limit and/or a motor. A limit ConstraintRevolute2D.EnableLimit forces the joint angle to remain between a lower ConstraintRevolute2D.LowerAngle and upper ConstraintRevolute2D.UpperAngle bound. 

The limit will apply as much torque as needed to make this happen. The limit range should include zero, otherwise the constraint will lurch when the simulation begins. A motor (ConstraintRevolute2D.EnableMotor) allows you to specify the constraint speed (the time derivative of the angle). The speed (ConstraintRevolute2D.MotorSpeed) can be negative or positive. 

When the maximum torque (ConstraintRevolute2D.MaxMotorTorque) is exceeded, the joint will slow down and can even reverse. You can use a motor to simulate friction. Just set the joint speed to zero, and set the maximum torque to some small, but significant value. The motor will try to prevent the constraint from rotating, but will yield to a significant load.
