Flash AS 实现好看的清晰的飘动云和风吹草动画

false, "normal", "none", "none", 1);
//Adjust the sway according to the grass's current sway and the windxpos
  grasscoords[coord][2]=Math.max(-maxsway,Math.min(maxsway,grasscoords[coord][2]+Math.max(-maxsway,Math.min(maxsway,(windxpos-grasscoords[coord][0])/100))))+(Math.random()*3-1.5);
//Move to the base of the blade of grass
  this.moveTo(grasscoords[coord][0],grasscoords[coord][1]);
//Draw a curved line to the new top of the blade of grass
  this.curveTo(grasscoords[coord][0],grasscoords[coord][1]-grasscontrol,grasscoords[coord][0]+grasscoords[coord][2],grasscoords[coord][1]-grassheight+Math.abs(grasscoords[coord][2]/2));
 }
}

然后回到主场景中，建立两个图层，下面的为云的图层，上面的为草的图层，这里我绘制了一个放草的框框。

按Ctrl+L打开库分别把草元件和云元件放到相应的图层。给草命名实例grass。

最后可以测试影片了！但是好象机器运行速度在减慢啊！祝你好运！
