Properties
cpFloat	angle
	The current ratchet position in radians.

cpFloat	phase
	The angular offset of the ratchet positions in radians.

cpFloat	ratchet
	The angle in radians of each ratchet position. Negative values cause the ratchet to operate in the opposite direction.

Detailed Description

Ratchet joints create rotary ratches similar to a socket wrench.

Method Documentation

Initialize a ratchet joint between the given bodies.

Parameters

phase	The angular offset of the ratchet positions in radians.
ratchet	The angle in radians of each ratchet position. Negative values cause the ratchet to operate in the opposite direction.

+ (ChipmunkRatchetJoint *) ratchetJointWithBodyA:	(ChipmunkBody *)	a
bodyB:	(ChipmunkBody *)	b
phase:	(cpFloat)	phase
ratchet:	(cpFloat)	ratchet

Create an autoreleased ratchet joint between the given bodies.

Parameters

phase	The angular offset of the ratchet positions in radians.
ratchet	The angle in radians of each ratchet position. Negative values cause the ratchet to operate in the opposite direction.
