[Bezier tween draw curve [SOLVED]]

I found the solution.

 

create a new Fla,and paste following code in Actions Frame.And you can see the result.

 

import flash.display.Sprite;

import com.greensock.TweenMax;

import com.greensock.plugins.BezierPlugin;

import com.greensock.plugins.BezierThroughPlugin;

 

var sp:Sprite=new Sprite();

addChild(sp);

 

sp.graphics.beginFill(0xff0000);

sp.graphics.drawRect(0,0,100,200);

sp.graphics.endFill();

 

TweenMax.to(sp,5,{bezierThrough:[{x:250,y:100},{x:50,y:200},{x:500,y:200}]});

 

this.graphics.lineStyle(1);

 

var xA:Array=[0,250,50,500];

var yA:Array=[0,100,200,200];

 

var bezierObj:Object=BezierPlugin.parseBeziers({"x":xA,"y":yA},true);

 

var pointCount:int=0;

while(pointCount

{

this.graphics.curveTo(bezierObj.x[pointCount][1],bezierObj.y[pointCount][1],bezierObj.x[pointCount][2],bezierObj.y[pointCount][2]);

pointCount++;

}
