Actionscript 3 从外部类更改主类上的变量

我想通过外部类video01中的函数terug将Main.as中的var filmAan更改为false

这是我的主要任务

package 
{
import flash.display.MovieClip;
import flash.events.MouseEvent;
import fl.video.*;

public class Main extends MovieClip 
{
    public function Main() 
    {
        trace( "hij werkt" ); 

        btn_1.addEventListener(MouseEvent.CLICK,speel1);
        btn_2.addEventListener(MouseEvent.CLICK,speel2);
        btn_3.addEventListener(MouseEvent.CLICK,speel3);
        btn_4.addEventListener(MouseEvent.CLICK,speel4);
        btn_5.addEventListener(MouseEvent.CLICK,speel5);
        btn_6.addEventListener(MouseEvent.CLICK,speel6);
        btn_7.addEventListener(MouseEvent.CLICK,speel7);
        btn_8.addEventListener(MouseEvent.CLICK,speel8);
        btn_9.addEventListener(MouseEvent.CLICK,speel9);

                trace("knop 9 uitgeschakeld");
            }
        }
    }
}   
}

这是我的视频01.as

package
{
import flash.display.MovieClip;
import flash.events.MouseEvent;

public class video01 extends MovieClip
{
    public function video01()
    {
        trace("movieclip 1 geladen");
        btn_terug.addEventListener(MouseEvent.CLICK, terug);
    }

    public function terug(evt:MouseEvent):void 
    {
        trace("knop ingedrukt");
        this.parent.removeChild(this);  

    }
}
}

如何从video01类更改Main.as中的变量

---

提前谢谢

看起来你的

video01

类是主类的子类。因此，您可以使用

parent

关键字访问

Main

类。为了不引发编译器错误，您需要强制转换父级：

从您的video01课程：

 Main(parent).filmAan = false;

---

thx，但是当我这样做时，我得到了这个错误：Main.as，第33行1114：public属性只能在包中使用。你得到这个错误是因为你在函数中定义了这个变量，move

public var filmAan=false在它所在的函数之外，使其成为类范围变量
