有2个类
个是自己个是敌人
自己类取名Ball1.as:package{//ball1类是玩家操作

}
}然后用
个fla文件把2个类化:importflash.text.*;
importflash.net.*;
varball:Ball1=Ball1(stage);//定义ball1
varballList:Array=Array;//定义balllist
for(vari:=0;i<20;i){//例子化balllist
ballList.push(Ball2(ball));
addChild(ballList);
ball.ballList=ballList;
}
addChild(ball);
varlable:TextField=TextField;
lable.text="sliz";
lable.x=530;
lable.y=380;
addChild(lable);
lable.addEventListener(MouseEvent.CLICK,clickHandler);
functionclickHandler(event:MouseEvent):void{
navigateToURL(URLRequest("http://space.flash8.net/space/?534614"));
