Inherits ChipmunkSpace.

Properties
NSUInteger	threads
	Number of threads to use for the solver. More...
Properties inherited from ChipmunkSpace
int	iterations
	The iteration count is how many solver passes the space should use when solving collisions and joints (default is 10). More...
cpVect	gravity
	Global gravity value to use for all rigid bodies in this space (default value is cpvzero).
cpFloat	damping
	Global viscous damping value to use for all rigid bodies in this space (default value is 1.0 which disables damping). More...
cpFloat	idleSpeedThreshold
	If a body is moving slower than this speed, it is considered idle. The default value is 0, which signals that the space should guess a good value based on the current gravity.
cpFloat	sleepTimeThreshold
	Elapsed time before a group of idle bodies is put to sleep (defaults to infinity which disables sleeping). More...
cpFloat	collisionSlop
	Amount of encouraged penetration between colliding shapes. More...
cpFloat	collisionBias
	Determines how fast overlapping shapes are pushed apart. More...
cpTimestamp	collisionPersistence
	Number of frames that contact information should persist. More...
cpSpace *	space
	Returns a pointer to the underlying cpSpace C struct.
ChipmunkBody *	staticBody
	The space's designated static body. More...
cpFloat	currentTimeStep
	Retrieves the current (if you are in a callback from [ChipmunkSpace step:]) or most recent (outside of a [ChipmunkSpace step:] call) timestep.
BOOL	locked
	Returns true if the space is currently executing a timestep.
id	userData
	An object that this space is associated with. More...

Additional Inherited Members
Public Types inherited from ChipmunkSpace
typedef void(^	ChipmunkPostStepBlock )(void)
	Block type used with [ChipmunkSpace addPostStepBlock:].
Instance Methods inherited from ChipmunkSpace
(void)	- setDefaultCollisionHandler:begin:preSolve:postSolve:separate:
	Set the default collision handler. More...
(void)	- addCollisionHandler:typeA:typeB:begin:preSolve:postSolve:separate:
	Set a collision handler to handle specific collision types. More...
(id)	- add:
	Add an object to the space. More...
(id)	- remove:
	Remove an object from the space. More...
(BOOL)	- contains:
	Check if a space already contains a particular object:
(id)	- smartAdd:
	If the space is locked and it's unsafe to call add: it will call addPostStepAddition: instead.
(id)	- smartRemove:
	If the space is locked and it's unsafe to call remove: it will call addPostStepRemoval: instead.
(NSArray *)	- addBounds:thickness:elasticity:friction:filter:collisionType:
	Handy utility method to add a border of collision segments around a box. More...
(BOOL)	- addPostStepCallback:selector:key:
	Define a callback to be run just before [ChipmunkSpace step:] finishes. More...
(BOOL)	- addPostStepBlock:key:
	Same as [ChipmunkSpace addPostStepCallback:] but with a block. The block is copied.
(void)	- addPostStepAddition:
	Add the Chipmunk Object to the space at the end of the step.
(void)	- addPostStepRemoval:
	Remove the Chipmunk Object from the space at the end of the step.
(NSArray *)	- pointQueryAll:maxDistance:filter:
	Return an array of ChipmunkNearestPointQueryInfo objects for shapes within maxDistance of point. More...
(ChipmunkPointQueryInfo *)	- pointQueryNearest:maxDistance:filter:
	Find the closest shape to a point that is within maxDistance of point. More...
(NSArray *)	- segmentQueryAllFrom:to:radius:filter:
	Return a NSArray of ChipmunkSegmentQueryInfo objects for all the shapes that overlap the segment. The objects are unsorted.
(ChipmunkSegmentQueryInfo *)	- segmentQueryFirstFrom:to:radius:filter:
	Returns the first shape that overlaps the given segment. The segment is treated as having the given group and layers.
(NSArray *)	- bbQueryAll:filter:
	Returns a NSArray of all shapes whose bounding boxes overlap the given bounding box. The box is treated as having the given group and layers.
(NSArray *)	- shapeQueryAll:
	Returns a NSArray of ChipmunkShapeQueryInfo objects for all the shapes that overlap shape.
(BOOL)	- shapeTest:
	Returns true if the shape overlaps anything in the space.
(NSArray *)	- bodies
	Get a copy of the list of all the bodies in the space.
(NSArray *)	- shapes
	Get a copy of the list of all the shapes in the space.
(NSArray *)	- constraints
	Get a copy of the list of all the constraints in the space.
(void)	- reindexStatic
	Update all the static shapes.
(void)	- reindexShape:
	Update the collision info for a single shape. More...
(void)	- reindexShapesForBody:
	Update the collision info for all shapes attached to a body.
(void)	- step:
	Step time forward. While variable timesteps may be used, a constant timestep will allow you to reduce CPU usage by using fewer iterations.
Class Methods inherited from ChipmunkSpace
(ChipmunkSpace *)	+ spaceFromCPSpace:
	Get the ChipmunkSpace object associciated with a cpSpace pointer. More...

Detailed Description

ChipmunkHastySpace is an Objective-Chipmunk wrapper for cpHastySpace.

Subclass this class instead of ChipmunkSpace if you want to enable the cpHastySpace optimizations. If ChipmunkHastySpace is linked correctly, calling [[ChipmunkSpace alloc] init] will actually return a ChipmunkHastySpace.

Property Documentation

- (NSUInteger) threads

readwritenonatomicassign

Number of threads to use for the solver.

Setting 0 will choose the thread count automatically (recommended). There is currently little benefit in using more than 2 threads. Defaults to 1.
