Member Function Documentation

create()

CardinalSplineBy * 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: local create(local t, local table).
@param duration In seconds.
@param point An PointArray.
@param tension Goodness of fit.

updatePosition()

void updatePosition ( const Vec2 & newPos )

overridevirtual

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

Parameters

newPos

The new position.

Reimplemented from CardinalSplineTo.
