#import <ChipmunkConstraint.h>
Inherits ChipmunkConstraint.
Instance Methods | |
| (id) | - initWithBodyA:bodyB:rate: |
| Initialize a simple motor between the given bodies and relative rotation rate in radians per second. | |
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 | |
| (ChipmunkSimpleMotor *) | + simpleMotorWithBodyA:bodyB:rate: |
| Create an autoreleased simple motor between the given bodies and relative rotation rate in radians per second. | |
Class Methods inherited from ChipmunkConstraint | |
| (ChipmunkConstraint *) | + constraintFromCPConstraint: |
| Get the ChipmunkConstraint object associciated with a cpConstraint pointer. More... | |
Properties | |
| cpFloat | rate |
| The relative rotation speed of the two bodies in radians per second. | |
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... | |
Simple motors make two objects spin relative to each other.
They are most often used with the ChipmunkConstraint.maxForce property set to a finite value.
