#import <ChipmunkConstraint.h>
Inherits ChipmunkConstraint.
Instance Methods | |
| (id) | - initWithBodyA:bodyB:phase:ratchet: |
| Initialize a ratchet joint between the given bodies. More... | |
Instance Methods inherited from ChipmunkConstraint | |
| (void) | - preSolve: |
| Override this method to update a constraints parameters just before running the physics each step. | |
| (void) | - postSolve: |
| Override this method to poll values from a constraint each frame after the physics runs. More... | |
Class Methods | |
| (ChipmunkRatchetJoint *) | + ratchetJointWithBodyA:bodyB:phase:ratchet: |
| Create an autoreleased ratchet joint between the given bodies. More... | |
Class Methods inherited from ChipmunkConstraint | |
| (ChipmunkConstraint *) | + constraintFromCPConstraint: |
| Get the ChipmunkConstraint object associciated with a cpConstraint pointer. More... | |
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. | |
Properties inherited from ChipmunkConstraint | |
| cpConstraint * | constraint |
| Returns a pointer to the underlying cpConstraint C struct. | |
| ChipmunkBody * | bodyA |
| The first ChipmunkBody the constraint controls. | |
| ChipmunkBody * | bodyB |
| The second ChipmunkBody the constraint controls. | |
| cpFloat | maxForce |
| Maximum force this constraint is allowed to use (defalts to infinity). More... | |
| cpFloat | errorBias |
| The rate at which joint error is corrected. More... | |
| cpFloat | maxBias |
| Maximum rate (speed) that a joint can be corrected at (defaults to infinity). More... | |
| BOOL | collideBodies |
| Whether or not the connected bodies should checked for collisions. More... | |
| cpFloat | impulse |
| Get the most recent impulse applied by this constraint. | |
| ChipmunkSpace * | space |
| Get the space the body is added to. | |
| id | userData |
| An object that this constraint is associated with. More... | |
