我不断收到此错误：ArgumentError：错误＃1063：代码上的参数计数不匹配：：SimonPad（）。预期为 2，得到 0。我不知道发生了什么，尤其是 uint。任何帮助将不胜感激。我在下面显示了两个代码块。它们基于 Actionscript 3.0 当我试图运行这些代码时，我没有在舞台上得到任何东西。该代码应该显示四个不同颜色的框，但它根本不起作用。请帮忙。

package code

{

import flash.display.MovieClip;
import flash.events.Event;


public class Main extends MovieClip
{


    private var pads:Array = new Array();

    public function Main()
    {
        var pad:SimonPad;

        pad = new SimonPad(0xAA0000, 0xFF0000);
        pad.x = 5;
        pad.y = 5;
        addChild(pad)
        pads.push(pad)

        pad = new SimonPad(0x0000AA, 0x6666FF);
        pad.x = 205;
        pad.y = 205;
        addChild(pad)
        pads.push(pad)

        pad = new SimonPad(0xAAAA00, 0xFFFF00);
        pad.x = 5;
        pad.y = 205;
        addChild(pad)
        pads.push(pad)

        pad = new SimonPad(0x00AA00, 0x00FF00);
        pad.x = 205;
        pad.y = 205;
        addChild(pad)
        pads.push(pad)

        addEventListener(Event.ENTER_FRAME, theFrame);
    }

    private function theFrame(e:Event):void
    {
        for (var i:int = 0; i < pads.length; i++) 
        {
            (pads[i] as SimonPad).update();
        }
    }
}

}

package code

{

import flash.display.Sprite;
import flash.display.Shape;
import flash.events.MouseEvent;


public class SimonPad extends Sprite
{


    private var dark:Shape;
    private var light:Shape;

    public function SimonPad(darkColor:uint, lightColor:uint)
    {
        dark = new Shape();
        dark.graphics.beginFill(darkColor, 1);
        dark.graphics.drawRect(0,0,190,190);
        dark.graphics.endFill();
        addChild(dark);

        light = new Shape();
        light.graphics.beginFill(lightColor, 1);
        light.graphics.drawRect(0,0,190,190);
        light.graphics.endFill();
        addChild(light);

        light.alpha = 0;

        mouseChildren = false;

        addEventListener(MouseEvent.CLICK, downClicked);
    }

    private function downClicked (e:MouseEvent):void
    {
        flash();
    }

    public function flash():void
    {
        light.alpha = 2;
    }

    public function update():void
    {
        if (light.alpha > 0)
        {
            light.alpha *= 0.85;

            if (light.alpha < 0.0125)
            {
                light.alpha = 0;
            }
        }
    }
}

}

看起来SimonPad您在设计时确实在您的舞台上手动放置了一个实例。请跟踪您的 Flash 项目中手动放置的SimonPad实例。此外，为了获得框架，您可以尝试这个技巧：在SimonPad()函数中，除了为构造函数参数提供默认值之外，您还可以添加以下行：

var e:Error=new Error();
trace(e.getStackTrace());

这将为您提供一个跟踪，at MainTimeline.frameXXX其中包含具有帧号的某些内容，或者at Sprite.constructChildren() at Sprite() at SomeClass()为您提供有关哪个类的库原型具有SimonPad引用的提示。
