flash as3.0里怎么设置属性

package {import flash.display.Sprite;import flash.events.MouseEvent;public class MyClass extends Sprite{public var r:Number=50;private var s:Number=0x123456;public var cir:Sprite;public function MyClass(){trace("this is my first class.")cir=myDrawCircle(r,s);trace("s="+s);}private function myDrawCircle(rr:Number,ss:uint){var circle=new Sprite();circle.graphics.lineStyle(1,0,1);circle.graphics.beginFill(ss);circle.graphics.drawCircle(100,100,rr);circle.graphics.endFill();return circle;}public function set sValue(value:Number){s=value;addChild(cir);}public function get sValue(){addChild(cir);return s;}}}package {import flash.display.Sprite;import flash.events.MouseEvent; import MyClass;public class MyClass111 extends MyClass{var circle:MyClass=new MyClass();public function MyClass111(){circle.addEventListener(MouseEvent.MOUSE_CLICK,onClick)addChild(circle);}private function onClick(event:MouseEvent):void{circle.r=circle.r+100;circle.x+=100;circle.sValue=circle.sValue;circle.sValue=circle.sValue+1000;addChild(circle);}}}想在点击圆之后，圆的尺寸和颜色都要变化，可惜只移动了位置。点击圆之前语句trace("this is my first class.")执行了两次，为什么。

Answer 1

改变mc的颜色用transform属性，给transform对象的colorTransform指定个新对象

Answer 2

执行了两次说明你调用了两次函数。
