先看效果：
Snow.as：
package{
import flash.display.*;
import flash.events.*;
public class Snow extends Sprite{
public var radius:Number;
public var angle:Number;
public var speed:Number;
public function Snow(){
init();
addEventListener(Event.ENTER_FRAME,enterFrameHandler);
}
public function init():void{
radius=Math.random()*2;

speed=Math.random()+1;
x=Math.random()*550;
y=0;
alpha=Math.random();
graphics.clear();
graphics.beginFill(0xffffff);
graphics.drawCircle(0,0,radius);
graphics.lineTo(100,100);
}
public function enterFrameHandler(e:Event):void{
x+=speed*Math.cos(angle);
y+=speed*Math.sin(angle);
if(y>400||x550){
init();
}
}
}
}
Snow.fla：
var num:int=0;
var lable:TextField=new TextField();
lable.textColor=0xffffff;
lable.htmlText = "sliz";
lable.addEventListener(MouseEvent.MOUSE_DOWN,mouseDownHandler);
lable.x=520;
lable.y=380;
addChild(lable);
stage.addEventListener(Event.ENTER_FRAME,enterFrameHandler);
function enterFrameHandler(e:Event):void {
if (num addChild(new Snow());
num++;
} else {
stage.removeEventListener(Event.ENTER_FRAME,enterFrameHandler);
}
}
function mouseDownHandler(e:MouseEvent):void {
navigateToURL( new URLRequest ("http://space.flash8.net/space/?534614" ) );
}
