1120:访问未定义的属性shuffledArray

请你帮助我,我是as3的新手,我正在尝试使用Fisher-Yates算法创建一个洗牌的牌组。当我使用ctrl-enter运行代码时,它编译时没有错误,但是当我尝试使用trace()输出它时;它回来了:

场景1,图层'动作',第1帧,第6行1120:访问未定义属性shuffledArray。

就像我说的我是新来的,这将是我做一些非常愚蠢的事情,但同样我被卡住了。

这是代码

package src.CardDeck
{
    public class CardDeck
    {
        public var allCards:Array = [];
        public var cardNames:Array;
        public var cardValues:Array;
        public var gameType:String;
        public var drawnCards:uint = 0;

        public function CardDeck(game:String)
        {
            gameType = game;
            cardNames = ["Ace","Two","Three",
                         "Four","Five","Six",
                         "Seven","Eight","Nine",
                         "Ten","Jack","Queen","King"];
            if(gameType == "texasholdem")
            {
                cardValues = [1,2,3,4,5,6,7,8,9,10,10,10,10];
            }
            makeSuit("Spade");
            makeSuit("Heart");
            makeSuit("Diamond");
            makeSuit("Club");
        }
        function makeSuit(suitString:String):void
        {
            var card:Object;

            for(var i:uint = 0; i < cardNames.length; i++)
            {
                card = {};
                card.cardType = suitString;
                card.cardName = cardNames[i];
                card.cardValue = cardValues[i];
                card.isDrawn = false;
                allCards.push(card);
            }
        }

        public function shuffleFisherYates():Array 
        {
            var shuffledArray:Array = [];
            var randomCardIndex: int;
            do 
            {
                randomCardIndex = Math.floor(Math.random()* allCards.length);
                shuffledArray.push(allCards[randomCardIndex]); // add to mix
                allCards.splice(randomCardIndex,1); // remove from deck
            }while(allCards.length); // Meaning while allCards.length != 0
            return shuffledArray;


        }
    }
}

这里是.fla动作层

import src.CardDeck.CardDeck;

var deck:CardDeck = new CardDeck("texasholdem");
trace(shuffledArray);

我知道这可能是愚蠢的事情,但我正在努力。

提前致谢!

var deck:CardDeck = new CardDeck("texasholdem");
trace(shuffledArray);

这不起作用,因为那里没有定义shuffledArray

尝试:

var deck:CardDeck = new CardDeck("texasholdem");
var array:Array = deck.shuffleFisherYates();

for(var i:int=0; i<array.length; i++)
{    
    trace(array[i].cardName);
    trace(array[i].cardType);
    trace(array[i].cardValue);
    trace(array[i].isDrawn);
}

“shuffledArray”是CardDeck对象内的属性。要访问其中的公共方法和属性,您需要使用点语法:

trace(deck.shuffleFisherYates());

但是,根据你正在做的事情,如果你的CardDeck对象是为了控制整个套牌,你可能不需要真正直接访问数组。
