as2.0的loading练习
本人不会as2.0只能多动手练习了。
多动手是最好的学习方法。
--------loading.as----------
class loading {
private var mc:movieclip;
private var loadmc:movieclip;
public function loading(mymc:movieclip, myloadmc:movieclip) {
mc = mymc;
loadmc = myloadmc;
//定义一个mc来放进度条和文本,定义一个空的loadmc放外部的swf
}
public function attchbarandtext(loadbar:string, mytext:string, x:number, y:number, depth:number):void {
//定义一个方法来摆放位置
mc.attachmovie(loadbar, "loadbar", depth);
mc.attachmovie(mytext, "mytext", depth+10);
mc.loadbar._x = x;
mc.loadbar._y = y;
mc.mytext._x = mc.loadbar._x+mc.loadbar._width-mc.mytext._width;
//将百份比放到最右边
mc.mytext._y = mc.loadbar._y+mc.loadbar._height;
//mc.mytext.pectext.text是里面的文本
mc.loadbar._xscale = 0;
//不能放到前面。不能不能放到文本不能放到右边
return;
}
private function loadoutswf(swfname:string):void {
mc._visible = true;
loadmc.loadmovie(swfname);
loadmc._alpha = 0;
//加载外部的文本
return;
}
public function getpec(num:number, swfname:string):void {
loadoutswf(swfname);
//调用内部函数
mc.onenterframe = function() {
var myloadingmc:movieclip = this._parent.loadmc;
//定义和取得数据
var total:number = myloadingmc.getbytestotal();
var loaded:number = myloadingmc.getbytesloaded();
var pec:number = math.floor((loaded*100)/total);
//trace("loaded="+loaded);
//trace("pec="+pec);
//trace("total="+total);
//百份比
if (total>5 && loaded>5) {
this.mytext.pectext.text = pec+"%";
this.loadbar._xscale = pec;
}
if (total>5) {
if (pec>=100) {
this._visible = false;
if (myloadingmc._alpha<100) {
myloadingmc._alpha += num;
} else {
//trace("done");
delete this.onenterframe;
}
}
}
};
}
}
-------------loading.fla---------
var myloading:loading = new loading(emptymc, loadmc);
myloading.attchbarandtext("loadbar", "mytext", 0, 0, 10);
myloading.getpec(5, "img.jpg");
///////////////
我应该写个画loadbar的类和一个建立文本的类，那么以后调用就方便多了。
