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

virtual CatmullRomTo* clone ( ) const
overridevirtual

returns a clone of action

Reimplemented from CardinalSplineTo.

static CatmullRomTo* 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 CatmullRomTo* reverse ( void  ) const
overridevirtual

returns a new action that performs the exactly the reverse action

Reimplemented from CardinalSplineTo.
