我正在尝试创建一个正方形数组，然后将它们添加到 6x12 网格中的舞台上，然后可以更改它们的颜色。我已经设法创建了一个数组数组并存储了正方形，但是我不知道现在如何将它们添加到网格中的舞台上。我是一名新程序员，所以如果我没有正确格式化我的代码，我提前道歉。感谢您的宝贵时间。

【解决方案1】：

您将一个相同的pixel 放入每一行。要制作更多像素，您需要为每行每列创建一个像素。为避免复制粘贴，您可以创建一个返回现成的Shape 对象的函数，然后在所有rowX.push() 语句中调用它。像这样：

function makePixel(fillColor:int=0xff0000):Shape {
    var pixel:Shape=new Shape();
    pixel.graphics.lineStyle(1, 0x000000, 1);
    pixel.graphics.beginFill(fillColor); // fill colour
    pixel.graphics.drawRect(0, 0, 30, 30); // (x spacing, y spacing, width, height)
    pixel.graphics.endFill(); // end of fill
    return pixel;
}
row1.push(makePixel());
row2.push(makePixel());
// etc
