Detailed Description

Abstract base class for collsion shape types.

Method Documentation

- (bool) pointQuery:

Check if a point in absolute coordinates lies within the shape.

+ (ChipmunkShape *) shapeFromCPShape: (cpShape *) shape

Get the ChipmunkShape object associciated with a cpShape pointer.

Undefined if the cpShape wasn't created using Objective-Chipmunk.

- (cpCollisionType) collisionType

readwritenonatomicassign

An object reference used as a collision type identifier.

This is used when defining collision handlers.

Attention: Like most delegate properties this is a weak reference and does not call retain.

- (id) data

readwritenonatomicassign

An object that this shape is associated with.

You can use this get a reference to your game object or controller object from within callbacks.

Attention: Like most delegate properties this is a weak reference and does not call retain. This prevents reference cycles from occuring.

- (cpGroup) group

readwritenonatomicassign

An object reference used as a collision group identifier.

Shapes with the same group do not collide.

Attention: Like most delegate properties this is a weak reference and does not call retain.

- (cpVect) surfaceVel

readwritenonatomicassign

The velocity of the shape's surface.

This velocity is used in the collision response when calculating the friction only.
