Detailed Description

Pivot joints hold two points on two bodies together allowing them to rotate freely around the pivot.

Method Documentation

- (id) initWithBodyA: (ChipmunkBody *)  a
bodyB: (ChipmunkBody *)  b
anchorA: (cpVect anchorA
anchorB: (cpVect anchorB 

Initialize a pivot joint between the two bodies with the two anchor points.

Make sure you have the bodies in the right place as the joint will fix itself as soon as you start simulating the space.

+ (ChipmunkPivotJoint *) pivotJointWithBodyA: (ChipmunkBody *)  a
bodyB: (ChipmunkBody *)  b
anchorA: (cpVect anchorA
anchorB: (cpVect anchorB 

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

Make sure you have the bodies in the right place as the joint will fix itself as soon as you start simulating the space.
