Question

早上好，我有一个由bankgrid生成的网格（var bankArray:Array），它将数组的值显示为gotoAndStop（该数字（f））一个彩色网格。所有正方形都是来自同一MovieClip（TBank）的子节点，一个接一个地生成数组中的水平（i）和垂直（j）位置。我试图让那些正方形可以拖延......徒劳无功：

var bankgrille:MovieClip = new MovieClip();
var bankList:Vector.<TBank> = new Vector.<TBank>();

var bankArray:Array = [
                     [0,0,0,0,0,0,0,0],
                     [0,0,0,0,0,0,0,0],
                     [0,0,0,0,0,0,0,0],
                     [0,0,1,0,0,0,0,0],
                     [0,0,2,0,1,0,0,0],
                     [0,2,2,2,2,0,0,0],
                     [0,1,2,2,1,0,0,0],
                     [0,2,1,1,2,1,1,0]
                     ];
var bankstock:Array = [
                     [0,0,0,0,0,0,0,0],
                     [0,0,0,0,0,0,0,0],
                     [0,0,0,0,0,0,0,0],
                     [0,0,0,0,0,0,0,0],
                     [0,0,0,0,0,0,0,0],
                     [0,0,0,0,0,0,0,0],
                     [0,0,0,0,0,0,0,0],
                     [0,0,0,0,0,0,0,0]
                     ];

function colorBank():void {
    for (var i:int=0; i<8; i++){                                    // boucle sur les 20 colonnes
        for (var j:int=0; j<8; j++){                                // boucle sur les 15 lignes de chaque colonne
            var f:int = bankArray[j][i]                             // valeur de la case

            if(f > 0)
            {                                                       // si la valeur de la case est supérieure à 0
                var tBank:TBank = new TBank()
                bankList.push(tBank);
                // création du modèle
                tBank.x = 320+i*20;                                     // position sur X
                tBank.y = 100+j*20;                                     // position sur Y
                tBank.gotoAndStop(f);
                bankgrille.addChild(tBank); 

            }

            else 
            {
                bankstock[j][i] = []                                
            }

        }
    }
}
colorBank();
addChild(bankgrille);

我未来的项目（也许让我的问题更有意义）： '之后，我想允许拖动方块并将它们放在另一个阵列上以改变第二种颜色'

Answer 1

在拖动影片剪辑时，

startDrag()是一个很好的起点。

您可以为整个网格分配MouseEvent侦听器，并使用event.currentTarget拖动特定元素：

bankgrille.addEventListener(MouseEvent.MOUSE_DOWN, onMouseDown);
bankgrille.addEventListener(MouseEvent.MOUSE_UP, onMouseUp);

function onMouseDown(e:MouseEvent):void
{
  e.currentTarget.startDrag();
}

function onMouseUp(e:MouseEvent):void
{
  e.currentTarget.stopDrag();
}
