Question

这段代码是什么意思？能具体翻译一下吗

Stage.scaleMode = "noScale";
this.createEmptyMovieClip("mc", this.getNextHighestDepth());
import flash.external.*;
ExternalInterface.addCallback("setNum", null, setNum);
ExternalInterface.addCallback("end", null, end);
function setNum(num) {
speed = num;
startFun();
changeNum(num);
}
function changeNum(num) {
if (tm_mc._currentframe<2) {
tm_mc.gotoAndPlay(2);
}
ro = jiao(num);
myTween = new mx.transitions.Tween(mc, "_x", mx.transitions.easing.None.easeNone, mc._x, num, 20);
myTween.onMotionChanged = function() {
step1.num.text = Math.round(this.position);
};
new mx.transitions.Tween(circleBg, "_rotation", mx.transitions.easing.None.easeNone, circleBg._rotation, ro, 20);
}
circleBg._rotation = -90;
setNum(0);
function jiao(i) {
if (i<0) {
i = 0;
}
if (i>1024*10) {
num = 45+45/(1024*20)*i;
} else if (i>1024) {
num = 45/(1024*10)*i;
} else {
num = -90+90/1024*i;
}
return (num);
}

function startFun() {
step1.num.text = 0;
step1._visible = true;
step2._visible = false;
}
startFun();
function end() {
changeNum(speed*10);
step1._visible = false;
step2._visible = true;
step2.num.htmlText = "下载速度：<font size='14' color='#58a6dd'>"+speed+"</font>KB/s 相当于："+"<font size='14' color='#58a6dd'>"+zhuanhuan(speed)+"</font>";
}
function zhuanhuan(num) {
if (num<100) {
return (num*10+"KB");
} else {
return (Math.round(num/10)/10+"M");
}
}

在Stage.scaleMode=“noScale”的情况;
this.createEmptyMovieClip（“MC”，this.getNextHighestDepth（））;
进口flash.external*。
ExternalInterface.addCallback（“setNum”，空，setNum）;
ExternalInterface.addCallback（“结束”，空，结束）;
功能setNum（NUM）{
速度= NUM;
startFun（）;
changeNum（NUM）;
}
功能changeNum（NUM）{
如果（tm_mc._currentframe<2）{
tm_mc.gotoAndPlay（2）;
}
RO=娇（NUM）;
myTween=新mx.transitions.Tween（MC，“_x”，mx.transitions.easing.None.easeNone，mc._x，NUM，20）;
myTween.onMotionChanged=功能（）{
step1.num.text= Math.round（this.position）;
};
新mx.transitions.Tween（circleBg，“_rotation”，mx.transitions.easing.None.easeNone，circleBg._rotation，RO，20）;
}
circleBg._rotation=-90;
setNum（0）;
功能娇（我）{
如果（I <0）{
I =0;
}
如果（I>1024*10）{
NUM=45+45/（1024*20）*我;
}否则，如果（我>1024）{
NUM=45/（1024*10）*我;
}其他{
NUM=-90+一千〇二十四分之九十○*我;
}
返回（NUM）;
}

功能startFun（）{
step1.num.text= 0;
step1._visible= TRUE;
step2._visible= FALSE;
}
startFun（）;
函数结束（）{
changeNum（速度*10）;
step1._visible= FALSE;
step2._visible= TRUE;
step2.num.htmlText=“下载速度：<字体大小='14'颜色='＃58a6dd'>”+速度+“</ FONT> KB/秒相当于：”+“<字体大小='14'颜色= “＃58a6dd'>”+ zhuanhuan（速度）+“</ FONT>”;
}
功能zhuanhuan（NUM）{
如果（NUM<100）{
回报（NUM*10+“KB”）;
}其他{
回报（Math.round（NUM/10）/10+“M”）;
}
