AS3 不接受构造函数

好吧，我已经提出这个问题一千次了，到目前为止没有人能够帮助我。我再次加注是因为我发现了一些新东西。过去我无法为类对象创建参数，每次这样做时都会出现以下错误

1136: Incorrect number of arguments.  Expected 0.

我注意到，作为 Movie Clip 或 Sprite 的子类的类能够具有构造函数参数，但作为子类的子类的类则不能。这背后有什么原因吗？

var cloud = new Cloud(5, 4);

package com.objects{
    import flash.events.Event;
    import flash.utils.*;

    public class Cloud extends gameObject {

        public var maxSpeed = 30;
        public var minSpeed = 5;
        public var cspeed:Number = 0;

        public function Cloud(min:Number = 0, max:Number = 0):void
        {
            var rand = Math.ceil(Math.random() * totalFrames);
            gotoAndStop(rand);
        }

        public function rand(min:Number, max:Number):void
        {
            maxSpeed = max;
            minSpeed = min;
            cspeed = (Math.ceil(Math.random() * maxSpeed)+ minSpeed);
        }

        override public function updateObject():void
        {
            eApi.setChildIndex(this, (eApi.numChildren - 1));
            y += cspeed;

            if(y > 800)
                garbage = true;
        }


    }
}

这是父类

package com.objects {

    import flash.display.MovieClip;
    import flash.display.Stage;
    import flash.events.*;
    import flash.utils.getTimer;

    public class gameObject extends MovieClip implements IgameObject
    {
        public static var EG:Engine;
        public var wPosX:Number = 0;
        public var wPosY:Number = 0;

        public var vPosX:Number = 0;
        public var vPosY:Number = 0;

        public var px:Number = 0;
        public var py:Number = 0;

        public var right:Number = 0;
        public var bottom:Number = 0;
        public var left:Number = 0;
        public var top:Number = 0;
        public var centerx:Number = 0;
        public var centery:Number = 0;
        static public var eApi:EngineApi;
        public var health:Number = 1;
        public var maxHealth:Number = 1;
        protected var lastTime:Number;
        public var ts:TargetSystem;

        public var col:Number;
        public var row:Number;
        public var map:Number;
        public var dead:Boolean = false;

        public var garbage:Boolean = false;

        public function gameObject():void {

        }//End Constructor

        static public function addEngine(e:EngineApi):void
        {
            eApi = e;
        }

        public function updateObject():void
        {

        }
        public function Attack(dir:Number = -40):void
        {

        }

        public function GarbageCollect():gameObject
        {
            return this;
        }

        public function getTime():int
        {
            var time:int = getTimer();
            return time;
        }
    }
}

如果您要附加一个symbol via 闪存集成开发环境 to a 定制类（MovieClip、Sprite、..）谁正在获取参数 flash不知道如何实例化这样的类，它怎么能猜到你期望的参数呢？

它只能实例化没有参数的类，您必须依靠另一种方式稍后初始化您的类或提供默认参数。
