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。var myLoading:MovieClip;

var loadInfo:MovieClip;

var _lineBgcolor = "0x666666";

var _lineColor = "0x0000FF";

var _lineLen:Number = 200;

var _lineH:Number = 3;

var _txtColor;

var _txtAlign:String = "center";

var tb:Number;

var txtFormat:TextFormat = new TextFormat("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(){

var lb:Number = _root.getBytesLoaded();

var percent: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();

delete this.onEnterFrame;

loadInfo.clear();

loadInfo.txt.text = "";

}

}
