package外のクラス

package外に別のクラスを書くとメインのクラスが長くなりすぎなくて、
全体が見やすくなるみたいです。

packageの外にクラスを書く練習2 – wonderfl build flash online

時計を表示する仕組みとしては、
まず、TextFieldをBitmapDataにdrawします。
[sourcecode language=”as3″]
var _bitmapData:BitmapData = new BitmapData(30, 30, false, 0xcFFFFF);
_bitmapData.draw(_tf);
var _bitmap:Bitmap = new Bitmap(_bitmapData);
[/sourcecode]

そして、getPixelによってピクセル毎の色を調べ、
黒が返ってくる座標を配列に記憶しています。
色は使い慣れている16進数にしてあります。
[sourcecode language=”as3″]
pixelValue = _bitmapData.getPixel(i, j);
pixelValue16 = pixelValue.toString(16);
if (pixelValue16 == "0") {
_pixelsX.push(i * 7);
_pixelsY.push(j * 7);
}
[/sourcecode]
全体のコード↓
もう少しすっきりさせれるように頑張ります。
