Question

我遇到了这个问题，闪光灯会给我一个回复 1046：未找到类型或不是编译时常量：mouseY

我试图在一个单独的类中滚动一个movieclip，我将它放入一个容器中到目前为止还没有工作！

帮助将不胜感激！

P.S我遵循了本教程http://forums.adobe.com/thread/892372

我的卷轴类：

package  {
import flash.events.MouseEvent;
import flash.display.MovieClip;
import flash.events.Event;
import flash.geom.Point;
import flash.ui.Mouse;

public class Scrolling {

    private var Touchscroll:Point = new Point;
    private var completeTween:Boolean;
    private var finalMouseY:int;
    private var mc:MovieClip = IconSpawn.container;
    private var currentY:mouseY = new mouseY;

    public function Scrolling() {
        // constructor code
        mc.addEventListener(MouseEvent.MOUSE_DOWN,onDown1)

    }

    public function onDown1(evt:MouseEvent):void
    {
        completeTween = false;
        //stage.addEventListener(MouseEvent.MOUSE_UP,onUp1);

        MovieClip(evt.currentTarget).addEventListener(Event.ENTER_FRAME,tweenF);
    }

    public function tweenF(e:Event):void
    {
        //var mc:MovieClip = MovieClip(evt.currentTarget);

        if(completeTween)
        {
            mc.y = .5*(mc.y + Math.min(800,finalMouseY));

            if(Math.abs(mc.y - Math.min(800, finalMouseY)) <1)
            {
                e.currentTarget.removeEventListener(Event.ENTER_FRAME,tweenF);
            }

        }
        else
        {
            mc.y = .5*(mc.y + Math.min(800, mouseY));
        }

    }
    public function onUp1(evt:MouseEvent):void
    {
        completeTween = true;
        finalMouseY = currentY;
        stage.removeEventListener(MouseEvent.MOUSE_UP,onUP1);
    }

}

}

编辑代码：

package  {
import flash.events.MouseEvent;
import flash.display.MovieClip;
import flash.events.Event;
import flash.geom.Point;
import flash.ui.Mouse;

public class Scrolling {

private var Touchscroll:Point = new Point;
private var completeTween:Boolean;
private var startMouseY:int;
private var finalMouseY:int;
private var mc:MovieClip = IconSpawn.container;
//private var CurrentY = mouseY

public function Scrolling() {
    // constructor code
    mc.addEventListener(MouseEvent.MOUSE_DOWN,onDown1)

}

public function onDown1(evt:MouseEvent):void
{
    startMouseY = mouseY;
    completeTween = false;
    stage.addEventListener(MouseEvent.MOUSE_UP,onUp1);

    MovieClip(evt.currentTarget).addEventListener(Event.ENTER_FRAME,tweenF);
}

public function tweenF(e:Event):void
{
    //var mc:MovieClip = MovieClip(evt.currentTarget);

    if(completeTween)
    {
        mc.y = .5*(mc.y + Math.min(800,finalMouseY));

        if(Math.abs(mc.y - Math.min(800, finalMouseY)) <1)
        {
            e.currentTarget.removeEventListener(Event.ENTER_FRAME,tweenF);
        }

    }
    else
    {
        mc.y = .5*(mc.y + Math.min(800, mouseY - startMouseY));
    }

}
public function onUp1(evt:MouseEvent):void
{
    completeTween = true;
    finalMouseY = mouseY - startMouseY;
    stage.removeEventListener(MouseEvent.MOUSE_UP,onUP1);
}

}
}

在第15行：private var currentY:mouseY = new mouseY;中，您已获取显示对象的公共属性，并尝试将其转换为类。不要那样做!!

只需将CurrentY声明为实例变量即可。在构造函数或更高版本中，设置CurrentY = mouseY。
