Macros

#define cpTrue   1
 true value.
 
#define cpFalse   0
 false value.
 
#define CP_NO_GROUP   ((cpGroup)0)
 Value for cpShape.group signifying that a shape is in no group.
 
#define CP_ALL_CATEGORIES   (~(cpBitmask)0)
 Value for cpShape.layers signifying that a shape is in every layer.
 
#define CP_WILDCARD_COLLISION_TYPE   (~(cpCollisionType)0)
 cpCollisionType value internally reserved for hashing wildcard handlers.

Typedef Documentation

typedef uint32_t cpCollisionID

Type used internally to cache colliding object info for cpCollideShapes().

Should be at least 32 bits.

typedef double cpFloat

Chipmunk's floating point type.

Can be reconfigured at compile time.
