Question

我现在几个小时都无法解决这个问题;（。我想在容器中添加一个孩子。这是我到目前为止所做的。所有问题都在类Creator中。这行par2.addChild（船）; //有效，但是这行par2.containerSDv.addChild（ship）; //错误：1119。

由于

    public class Main extends MovieClip
{
    private var containerSD:Container = new Container;
    private var ship:Ship2;

    public function Main()
    {
        // constructor code
        stage.addChild(containerSD);
        //ship = new Ship2;
        //containerSD.addChild(ship);

    }
}

    public class AddChild2 extends SimpleButton
{
    private var creatorche:Creator = new Creator;
    private var s:Ship2;

    public function AddChild2()
    {
        // constructor code
        addEventListener(MouseEvent.CLICK, onCLICK)
    }

    private function onCLICK(e:MouseEvent)
    {
        s = new Ship2;
        creatorche.onCreator(s, stage);
    }
}

    public class Creator extends MovieClip
{
    private var ship:MovieClip;
    private var containerSDv:Container = new Container;

    public function Creator()
    {
        // constructor code
    }

    public function onCreator(par1:MovieClip, par2:Stage)
    {
        ship = par1;
        //par2.addChild(ship); //works
        par2.containerSDv.addChild(ship); //error:1119
        ship.x = Math.random() * 200;
        ship.y = Math.random() * 200;
    }

}

我认为您可能需要退后一步，重新评估您的整体设计和目标。

考虑这种方法：

public class Main extends MovieClip
{
    private var container:Sprite = new Sprite;
    private var newShipButton:NewShipButton = new NewShipButton;
    private var creator:Creator;

    public function Main()
    {
        creator = new Creator;
        addChild(container);
        addChild(newShipButton);

        newShipButton.addEventListener(MouseEvent.CLICK, newShipButtonHandler);

    }

    private function newShipButtonHandler(e:MouseEvent):void
    {
        // shipStyle would be a MovieClip of the artwork for a given ship.
        var ship:Ship = creator.makeShip(shipStyle, speed, power, container);
        ship.x = Math.random() * 200;
        ship.y = Math.random() * 200;
    }

}

以下是Creator类

的示例

public class Creator
{

    public function Creator()
    {
        // constructor code
    }

    public function makeShip(style:MovieClip, speed:Number, power:Number, container:MovieClip):Ship
    {
        var ship:Ship = new Ship(style);
        ship.speed = speed;
        ship.power = power;
        container.addChild(ship);
        return ship;
    }

}

我做了一些假设，比如你有一个Ship类会扩展一个MovieClip / Sprite并且有艺术作品，而你的NewShipButton类将扩展SimpleButton并有艺术作品。

如果这不符合您的需求，请解释您尝试做的不适合这种非常简单的设计。

我看过很多帖子似乎让事情变得比他们需要的要困难得多。也许有充分的理由，但如果是这样，请解释为什么上述方法不适用于您的目的。

如果我给Container命名并取消选中设置中的严格模式，我的代码就可以了。我发现了有关DisplayObjectContainer http://joshblog.net/2007/07/12/disabling-actionscript-3-strict-mode-in-flash-cs3/

的非常有用的文章

    public class Creator extends MovieClip
{
    private var ship:MovieClip;
    private var containerSDv:Container = new Container;

    public function Creator()
    {
        // constructor code
    }

    public function onCreator(par1:MovieClip, par2:Stage)
    {
        ship = par1;
        //par2.addChild(ship); //works
        par2.getChildByName("contain").addChild(ship); //error:1119
        ship.x = Math.random() * 200;
        ship.y = Math.random() * 200;
    }

}

    public class Main extends MovieClip
{
    private var containerSD:Container = new Container;
    private var ship:Ship2;

    public function Main()
    {
        // constructor code
        stage.addChild(containerSD).name = "contain";
        containerSD.x = 0;
        containerSD.y = 0;


    }
}
