Classpublic class Bezier2D

Allows for Objects to follow a 2D bezier path. This path is made from a list of points these points are either control points or through points for the bezier.

Method detail
addAt()method
public function addAt(index:int, pt:Point):void

Adds a Point into the Bezier path at the specified index.

Parameters
index:int — The index for which to insert the Point.
 
pt:Point — The Point to insert at the index.
index()method 
public function index(index:int):Point

Parameters
index:int — The position to return a Point from.

Returns
Point — Returns a Point at the specified index.
push()method 
public function push(pt:Point):void

Pushes a Point into the Bezier path.

Parameters
pt:Point — The Point which will be added to the end of the bezier path.
remove()method 
public function remove(pt:Point):void

Removes a Point from the Bezier path.

Parameters
pt:Point — The Point you would like to remove from the bezier path.
removeAt()method 
public function removeAt(index:int, count:int = 1):void

Removes one or more Point(s) at the specified index and count from the Bezier path.

Parameters
index:int — The index to start removing nodes from the Bezier path.
 
count:int (default = 1) — the Number of nodes to remove from the Bezier path. If this is 0 no nodes are removed.
