Detailed Description

Constrains the angle between two bodies.

This joint is often used in conjuction with a separate ChipmunkPivotJoint in order to limit the rotation around the pivot.

Method Documentation

Create an autoreleased rotary limit joint between the two bodies and angular range in radians.

Make sure you have the bodies in the right place as the joint will snap into shape as soon as you start simulating the space.
