Detailed Description

Create an autoreleased groove joint between the two bodies.

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.

Parameters

grooveA	The start of the line segment on the first body.
grooveB	The end of the line segment on the first body.
anchorB	The anchor point on the second body that is held to the line segment on the first.

Initialize a groove joint between the two bodies.

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.

Parameters

grooveA	The start of the line segment on the first body.
grooveB	The end of the line segment on the first body.
anchorB	The anchor point on the second body that is held to the line segment on the first.
