本文介绍如何利用Rectangle类实现Flash舞台上的对象拖拽功能，通过设置鼠标事件监听和对象属性，实现对象的精准定位和缩放。
import flash.geom.Rectangle;
var left:Number=mc.back.x;
var right:Number=mc.back.width-mc.drug.width;
stage.addEventListener(MouseEvent.MOUSE_UP,stopdrag);
mc.drug.addEventListener(MouseEvent.MOUSE_DOWN,startdrag);
function startdrag(event:MouseEvent):void {
var rect:Rectangle=new Rectangle(left,0,right,0);
mc.drug.startDrag(false,rect);
}
function stopdrag(event:MouseEvent):void {
//trace(event.currentTarget.x/292);
mc.drug.stopDrag();
ball.scaleY=ball.scaleX=mc.drug.x/292;
}
var left:Number=mc.back.x;
var right:Number=mc.back.width-mc.drug.width;
stage.addEventListener(MouseEvent.MOUSE_UP,stopdrag);
mc.drug.addEventListener(MouseEvent.MOUSE_DOWN,startdrag);
function startdrag(event:MouseEvent):void {
var rect:Rectangle=new Rectangle(left,0,right,0);
mc.drug.startDrag(false,rect);
}
function stopdrag(event:MouseEvent):void {
//trace(event.currentTarget.x/292);
mc.drug.stopDrag();
ball.scaleY=ball.scaleX=mc.drug.x/292;
}
