我做了一个动画
就差一个loading动画了，我做了一个！可是并没有效果！那位大虾帮帮忙诊断一下！
loop关键帧
byteloaded = _root.getBytesLoaded();
bytetotal = _root.getBytesTotal();
loaded = int(byteloaded /bytetotal * 100);
t = getTimer ();
// K
percent = loaded + "% ( " + int(byteloaded/1000) + " K / " + int(bytetotal/1000) + " K )";
percent = percent + "\r下载速度：" + int(byteloaded/t * 100)/100 + " K/s";
load_bar.gotoAndStop( loaded );
// Time
timeloaded = int(t/1000);
timeremain = int(timeloaded * (bytetotal- byteloaded) / byteloaded);
timeremain = int(timeremain / 60) + "\'" + int(timeremain % 60) + "\"";
timeloaded = int(timeloaded / 60) + "\'" + int(timeloaded % 60) + "\"";
downloadtime = "已用时间：" + timeloaded + "\r" + "剩余时间：" + timeremain;
-----------------------------------------------------------------------------------------------------------------------------------
if (byteloaded == bytetotal) {
gotoAndPlay ("Scene 4", "end");
} else {
gotoAndPlay ("loop");
}

我做的是scene4为开始动画！多个场景。Text

具体怎么做啊？帮忙！
