Chipmunk Unsafe Shape Operations

Functions
void	cpCircleShapeSetRadius (cpShape *shape, cpFloat radius)
	Set the radius of a circle shape.
void	cpCircleShapeSetOffset (cpShape *shape, cpVect offset)
	Set the offset of a circle shape.
void	cpSegmentShapeSetEndpoints (cpShape *shape, cpVect a, cpVect b)
	Set the endpoints of a segment shape.
void	cpSegmentShapeSetRadius (cpShape *shape, cpFloat radius)
	Set the radius of a segment shape.
void	cpPolyShapeSetVerts (cpShape *shape, int numVerts, cpVect *verts, cpVect offset)
	Set the vertexes of a poly shape.

Detailed Description

These functions are used for mutating collision shapes. Chipmunk does not have any way to get velocity information on changing shapes, so the results will be unrealistic. You must explicity include the chipmunk_unsafe.h header to use them.
