Member Function Documentation

virtual CardinalSplineTo* clone ( ) const
overridevirtual

returns a clone of action

Implements ActionInterval.

Reimplemented in CatmullRomBy, CatmullRomTo, and CardinalSplineBy.

static CardinalSplineTo* create ( float  duration,
PointArray points,
float  tension 
)
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 t,var table)
in lua: lcaol create(local t, local table)
PointArray* getPoints ( )
inline
bool initWithDuration ( float  duration,
PointArray points,
float  tension 
)

initializes the action with a duration and an array of points

virtual CardinalSplineTo* reverse ( ) const
overridevirtual

returns a new action that performs the exactly the reverse action

Implements ActionInterval.

Reimplemented in CatmullRomBy, CatmullRomTo, and CardinalSplineBy.

void setPoints ( PointArray points)
inline
virtual void startWithTarget ( Node target)
overridevirtual

called before the action start. It will also set the target.

Reimplemented from ActionInterval.

Reimplemented in CardinalSplineBy.

virtual void update ( float  time)
overridevirtual

called once per frame.

time a value between 0 and 1

For example:

  • 0 means that the action just started
  • 0.5 means that the action is in the middle
  • 1 means that the action is over

Reimplemented from Action.

virtual void updatePosition ( Point newPos)
virtual

Reimplemented in CardinalSplineBy.
