Basic Types

Most of these types can be configured at compile time. More...

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_LAYERS   (~(cpLayers)0)
	Value for cpShape.layers signifying that a shape is in every layer.

Typedefs
typedef double	cpFloat
	Chipmunk's floating point type. More...
typedef uintptr_t	cpHashValue
	Hash value type.
typedef int	cpBool
	Chipmunk's boolean type.
typedef void *	cpDataPointer
	Type used for user data pointers.
typedef uintptr_t	cpCollisionType
	Type used for cpSpace.collision_type.
typedef uintptr_t	cpGroup
	Type used for cpShape.group.
typedef unsigned int	cpLayers
	Type used for cpShape.layers.
typedef unsigned int	cpTimestamp
	Type used for various timestamps in Chipmunk.

Functions
static cpFloat	cpfmax (cpFloat a, cpFloat b)
	Return the max of two cpFloats.
static cpFloat	cpfmin (cpFloat a, cpFloat b)
	Return the min of two cpFloats.
static cpFloat	cpfabs (cpFloat f)
	Return the absolute value of a cpFloat.
static cpFloat	cpfclamp (cpFloat f, cpFloat min, cpFloat max)
	Clamp f to be between min and max.
static cpFloat	cpfclamp01 (cpFloat f)
	Clamp f to be between 0 and 1.
static cpFloat	cpflerp (cpFloat f1, cpFloat f2, cpFloat t)
	Linearly interpolate (or extrapolate) between f1 and f2 by t percent.
static cpFloat	cpflerpconst (cpFloat f1, cpFloat f2, cpFloat d)
	Linearly interpolate from f1 to f2 by no more than d.
