使用Flash Drawing API 动态画棋盘

AS3 精进中，发现graphics.drawPath()这个方法相当好用，于是写了一个小例子。

package {

importflash.display.Sprite;
importflash.display.Graphics;
importflash.display.StageAlign;

[SWF(backgroundColor=0xfffff0,width=500,height=500)]
publicclassChessBoard extends Sprite {

privatevarcellSize:Number= 50;
privatevarcount:int= 5;

privatevarg:Graphics;

privatevardatas:Vector.<Number>;
privatevarcommands:Vector.<int>;

publicfunction ChessBoard() {
   stage.align= StageAlign.TOP;

   g = graphics;
   g.clear();

   datas=newVector.<Number>();
   commands= new Vector.<int>();

   for(vari:int= 0;i<count;i++){
    commands.push(1,2,2,2,2);
    varinitY:Number= cellSize*i*2;
    datas.push(0,initY,
         count*cellSize*2,initY,
         count*cellSize*2,initY+cellSize,
         0,initY+cellSize,
         0,initY);

    commands.push(1,2,2,2,2);
    varinitX:Number= cellSize*i*2;
    datas.push(initX,0,
         initX,count*cellSize*2,
         initX+cellSize,count*cellSize*2,
         initX+cellSize,0,
         initX,0);
   }

   g.beginFill(0x000000);
   g.drawPath(commands,datas);
}
}
}
