Detailed Description

Pin joints hold a set distance between points on two bodies.

Think of them as connecting a solid pin or rod between the two anchor points.

Method Documentation

Initialize a pin joint between the two bodies with the given anchor points.

The distance is calculated when the joint is initialized. It can be set explicitly using the property.

+ (ChipmunkPinJoint *) pinJointWithBodyA:	(ChipmunkBody *)	a
bodyB:	(ChipmunkBody *)	b
anchorA:	(cpVect)	anchorA
anchorB:	(cpVect)	anchorB

Create an autoreleased pin joint between the two bodies with the given anchor points.

The distance is calculated when the joint is initialized. It can be set explicitly using the property.
