Detailed Description

An action that moves the target with a CatmullRom curve to a destination point.

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

create()

CatmullRomTo * create ( float dt, PointArray * points )

static

Creates an action with a Cardinal Spline array of points and tension.

Parameters

dt	In seconds.
points	An PointArray. When this function bound to js or lua,the input params are changed. In js: var create(var dt,var table). In lua: local create(local dt, local table).

initWithDuration()

bool initWithDuration	(	float	dt,
		PointArray *	points )

Initializes the action with a duration and an array of points.

Parameters

dt	In seconds.
points	An PointArray.
