Member Function Documentation

create()

static CardinalSplineTo * create ( float duration, PointArray * points, float tension )

static

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

Parameters

duration	In seconds.
points	An PointArray.
tension	Goodness of fit. When this function bound to js or lua,the input params are changed. In js: var create(var t,var table) In lua: local create(local t, local table)

initWithDuration()

bool initWithDuration	(	float	duration,
		PointArray *	points,
		float	tension )

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

Parameters

duration	In seconds.
points	An PointArray.
tension	Goodness of fit.

updatePosition()

virtual void updatePosition ( const Vec2 & newPos )

virtual

It will update the target position and change the _previousPosition to newPos.

Parameters

newPos

The new position.

Reimplemented in CardinalSplineBy.

getPoints()

PointArray * getPoints ( )

inline

Return a PointArray.

Returns

A PointArray.

update()

virtual void update ( float time )

overridevirtual

Parameters

time	In seconds.
