Detailed Description

An action that moves the target with a CatmullRom curve by a certain distance.

A Catmull Rom is a Cardinal Spline with a tension of 0.5. http://en.wikipedia.org/wiki/Cubic_Hermite_spline#Catmull.E2.80.93Rom_spline

Member Function Documentation

virtual CatmullRomBy* clone ( ) const

overridevirtual

returns a clone of action

Reimplemented from CardinalSplineBy.

static CatmullRomBy* create	(	float	dt,
		PointArray *	points
	)

static

creates an action with a Cardinal Spline array of points and tension

when this function bound to js or lua,the input params are changed
in js: var create(var dt,var table)
in lua: lcaol create(local dt, local table)

bool initWithDuration	(	float	dt,
		PointArray *	points
	)

initializes the action with a duration and an array of points

virtual CatmullRomBy* reverse ( ) const

overridevirtual

returns a new action that performs the exactly the reverse action

Reimplemented from CardinalSplineBy.
