求助，这段代码什么意思？
getURL("FSCommand:trapallkeys", 1);
getURL("FSCommand:allowscale", 0);
stage.showMenu = false;
duplicateMovieClip("fr", "frame", 100010);
_global.r = this;
stop ();
onEnterFrame = function ()
{
persen = Math.floor(this.getBytesLoaded() / this.getBytesTotal() * 100);
if (persen == 100)
{
r.udamusik = 0;
r.music = 1;
delete onEnterFrame;
gotoAndStop("menu");
} // end if
};
stop ();

[解决办法]
