题 目:Flash中背景跟随时间变化
假如flash中，我们想实现一张图片随着电脑时间的变换，图片也发生变化，形成早晨，晚上等效果。（假如多个图片，也能用这个方法实现，下面，我们看一下案例）：
_clip_image001.jpg)
相对应的脚本：
functiontimes()
{
hh=newDate();
xiaoshi=hh.getHours();
mm=newDate();
fengzhong=mm.getMinutes();
nowtime=xiaoshi*60 fengzhong;
if(nowtime>=0&&nowtime<=300||nowtime>1200&&nowtime<1440)

特别说明：这个代码最下面不是用来控制背景变化的，而是用来控制到了晚上月亮出现的位置，星星的位置。白天这些画面消失的控制。
