Question

我想通过外部类video01中的函数terug在我的Main.as中将var filmAan更改为false。

这是我的Main.as

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);

        var mc_video01:MovieClip = new video01();
        var mc_video02:MovieClip = new video02();
        var mc_video03:MovieClip = new video03();

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

这是我的video01.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);  

    }
}
}

我究竟如何从video01类更改Main.as中的var ??

提前谢谢！

Answer 1

看起来您的video01班级是Main班级的孩子。因此，您可以使用parent关键字来访问Main类。您需要强制转换父级以便不抛出编译器错误：

来自你的video01课程：

 Main(parent).filmAan = false;

从外部类更改主类的变量
