Question

我在下面有这个类结构

 public class Main extends Sprite
 {
       private var myObject:MyObject;
       private var mySecondObject:MySecondObject;
       private var myThirdObject:MyThirdObject;

       public function Main()
       {
            myObject = new MyObject();// also extends sprite
            addChild(myObject );

            mySecondsObject = new MySecondObject(this);
            addChild(mySecondsObject);

            myThirdObject = new MyThirdObject(this);
            addChild(myThirdObject);
       }

       public function getMyObject():MyObject
       {
           return myObject;
       }
 }

 public class MySecondObject extends Sprite
 {
       private var _main:Main;
       private var _myObject:MyObject;

       public function MySecondObject(main:Main)
       {
           _main = main;
           _myObject = _main.getMyObject();              
           // do some stuff with _myObject, add on enter frame listener etc...

       }
       public function start(): { /* do some stuff */}
       public function stop(): { /* do some stuff */}
 }

 public class MyThirdObject extends Sprite
 {
       private var _main:Main;
       private var _myObject:MyObject;

       public function MyThirdObject(main:Main)
       {
           _main = main;
           _myObject = _main.getMyObject();              
           // do some stuff with _myObject, add on enter frame listener etc...

       }
        public function start(): { /* do some stuff */}
       public function stop(): { /* do some stuff */}
 }

当我使用MySecondObject和MyThirdObject

执行此操作时出现的问题是MyObject的sprite消失了

 MySecondObject.stop();
 MyThirdObject.start();

MyObject仍然存在于内存中，但我无法在舞台上看到它。 WTF ??? ：）

为了说清楚我不会使用removeChild（）从舞台上删除任何内容。

我试图解决的问题是我想拥有从MySecondObject和MyThirdObject更新MyObject状态的访问器

Answer 1

问题解决了。我改为在舞台上添加所有的孩子，比如this.stage.addChild（child）而不是this.addChild（child），所以现在它可以正常工作并在开始/停止后显示舞台上的所有对象

精灵在AS3中消失了
