Actionscript 3：試圖創建一個隨機數組

Question

即時通訊嘗試創建一個隨機數組，每次啓動應用程序時將改變我的圖片（在tilelist中）的位置。希望你能理解尋找什麼即時通訊的，我真的不知道如何正確地鏈接在這裏代碼：/

我認爲它更容易簡單地複製到閃存和視圖從那裏

謝謝:)

這裏是我的代碼：

flash.events.MouseEvent; 

btn_back.addEventListener(MouseEvent.CLICK, ftilbake); 


function ftilbake(evt:MouseEvent) 
{ 
    gotoAndStop(1); 
} 


var heroArray:Array = new Array(); 
var randomizeArray:Array = new Array(); 

createArrays() 

function createArrays() 
{ 
heroArray[0] = new Array("Rumble","Garen","Lulu","Corki","Warwick"); 

heroArray[1] = new Array("Bilder/Champions/Rumble.jpg","Bilder/Champions/Garen.jpg","Bilder/Champions/Lulu.jpg","Bilder/Champions/Corki.jpg","Bilder/Champions/Warwick.jpg"); 

heroArray[2] = new Array("Bilder/Champions/Rumble1.jpg","Bilder/Champions/Garen1.jpg","Bilder/Champions/Lulu1.jpg","Bilder/Champions/Corki1.jpg","Bilder/Champions/Warwick1.jpg"); 

heroArray[3] = new Array("the Mechanized Menace","the Might of Demacia","the Fae Sorceress","the Daring Bombardier","the Blood Hunter"); 
heroArray[4] = new Array(0,0,0,0,0); 
heroArray[5] = new Array("Rumble.wav","Garen.wav","Lulu.wav","Corki.wav","Warwick.wav"); 
randomizeArray[0] = new Array(); 
randomizeArray[1] = new Array(); 
randomizeArray[2] = new Array(); 
randomizeArray[3] = new Array(); 
randomizeArray[4] = new Array(); 

//randomizing the positions in the array(?) 
var randomPos:int = 0; 
for (var i:int = 0; i < heroArray.length; i++) 
{ 
    randomPos = int(Math.random() * heroArray[0].length); 
    while (randomizeArray[randomPos][0] != null) 
    { 
     randomPos = int(Math.random() * heroArray.length); 
    } 
} 
} 


var totalKlikk:int = 0;

Answer 1

陣列隨機化的東西，所以我結束了創建爲它我的陣列工具類的靜態方法，該方法非常頻繁出現在我的所有項目。

它使用Fisher–Yates shuffle，它應該是用於混洗數組內容的最無偏（高效？）算法。有可能是這樣做的更快的方式（如使用array.sortOn（）方法，但我不知道他們得到的結果如何公正相比，這一個。）

洗牌方法：

/** 
    * shuffle the given array 
    * @param array 
    * @return 
    */ 
    public static function shuffle(array:Array):Array 
    { 

     var index :int; 
     var item :*; 
     var limit :int = array.length as int; 

     for (var i:int = limit-1; i >= 0 ; --i) 
     { 
      index   = Math.floor(Math.random() * (i + 1)); 
      item   = array[index]; 
      array[index] = array[i]; 
      array[i]  = item; 
     } 

     return array; 

    } 

示例：

var myArray:Array = new Array("Red","Orange","Yellow","Green","Blue"); 

myArray   = ArrayUtils.shuffle(myArray); 

其中ArrayUtils是我使用的Array Utility類的名稱。當然如果你不想使用工具類，你可以直接使用這個函數。

Answer 2

試試這個

while (heroArray.length > 0) { 
    randomizeArray.push(heroArray.splice(Math.round(Math.random() * (heroArray.length - 1)), 1)[0]); 
} 

只是斯塔雖然tiate randomizeArray，並且不要用像你的源代碼那樣的空數組填充它！

Answer 3

我建議創建一個單獨的對象來保存相關數據，並使用該對象類型的單個Array/Vector。

要回答你的問題，隨機化一個數組對於array.sort（）和一個隨機選擇函數來說相當容易。這個方法也可以用來隨機化任何數組。你不需要拼接數組或迭代。

function sortOnRandom(a:Object, b:Object):Number{ 
    if(Math.random() > 0.5){ 
    return 1; 
    }else{ 
    return -1; 
    } 
} 

myArray.sort(sortOnRandom);
