Question

我正在使用HTML 5和JS进行骰子游戏。现在我需要预加载骰子图像。我正在使用preloadJS库。所以我的问题是如何在不为每个骰子编写相同代码的情况下预加载两个或更多清单？请看我的例子。

我的清单文件是：dice_twos，dice_threes，dice_fours，dice_fives，dice_sixes。 * 我有一个骰子的50张图片 *

var n=0;
var diceRegX = 45;//X registration point for dice 
var diceRegY = 45;//Y registration point for dice 

for(var i=0; i<50;i++){
    dice_twos.push({ src: "Assets/DiceImages/ONE_Main." + i + ".png", id: "dice" + i, reelImg: false });
    dice_threes.push({ src: "Assets/DiceImages/ONE_Main." + i + ".png", id: "dice" + i, reelImg: false });
    dice_fours.push({ src: "Assets/DiceImages/ONE_Main." + i + ".png", id: "dice" + i, reelImg: false });
    dice_fives.push({ src: "Assets/DiceImages/ONE_Main." + i + ".png", id: "dice" + i, reelImg: false });
    dice_sixes.push({ src: "Assets/DiceImages/ONE_Main." + i + ".png", id: "dice" + i, reelImg: false });
}
preload = new createjs.PreloadJS();
preload.onFileLoad = handleFileLoad;
preload.onProgress = handleOverallProgress;
preload.onFileProgress = handleFileProgress;
preload.onError = handleFileError;

function stop() {
    if (preload != null) {
        preload.close();
    }
}

function loadAll() {
    while (dice_twos.length > 0) {
        loadAnother();
    }
}

function loadAnother() {
    var item1 = dice_twos.shift();
    handleFileLoad(item1);
}

// File complete handler 
function handleFileLoad(event1) {
    dice_1[n] = new createjs.Bitmap(event1.src);
    dice_1[n].name = ('dice' + (n + 1));
    dice_1[n].regX = (diceRegX - 5);
    dice_1[n].regY = (diceRegY - 5);
    dice_1[n].x = (canvas.width + 80);
    dice_1[n].y = (canvas.height / 2);
    n++;
}

我试图将另一个参数传递给handleFileLoad函数，但似乎不起作用。任何帮助将不胜感激。感谢
