一个简单易用的进度条

把下面的代码加到-root第一桢就OK了。varmyLoading:MovieClip;

varloadInfo:MovieClip;

var_lineBgcolor="0x666666";

var_lineColor="0x0000FF";

var_lineLen:Number=200;

var_lineH:Number=3;

var_txtColor;

var_txtAlign:String="center";

vartb:Number;

vartxtFormat:TextFormat=newTextFormat("Arial",null,0x000000,true);myLoading=_root.createEmptyMovieClip("myLoading",10);//进度条

loadInfo=myLoading.createEmptyMovieClip("line",10);

loadInfo.lineStyle(1,_lineColor,20);

loadInfo.moveTo(0,0);

loadInfo.lineTo(_lineLen,0);

loadInfo.lineTo(_lineLen,_lineH);

loadInfo.lineTo(0,_lineH);

loadInfo.lineTo(0,0);//进度显示文本

loadInfo.createTextField("txt",30,0,0,_lineLen,22);

loadInfo.txt.autoSize=_txtAlign;//设置进度条的位置（居中于主场景）

loadInfo._x=(Stage.width-_lineLen)/2;

loadInfo._y=Stage.height/2;//获得影片大小并stop，再onEnterFrame

tb=_root.getBytesTotal();

_root.stop();

myLoading.onEnterFrame=function(){

varlb:Number=_root.getBytesLoaded();

varpercent:Number=Math.round(lb/tb*100);

loadInfo.txt.text=percent+"%";

loadInfo.txt.setTextFormat(txtFormat);

loadInfo.lineStyle(_lineH,_lineBgcolor,10);

loadInfo.moveTo(0,_lineH/2);

loadInfo.lineTo(percent*_lineLen/100,_lineH/2);

if(percent==100){

_root.play();

deletethis.onEnterFrame;

loadInfo.clear();

loadInfo.txt.text="";

}

}
