loading 与 bar 节点为 建立的 progreebar 组件 barnumber 为加载进度的百分比显示 为label组件节点
注意：total length 的数字 为 bar 节点背景图片的 宽度
代码部分：
loadres:function(){
var self = this;
var loadbar = this.loadbar;
var loadtext = this.loadtext;
var login_button = this.login_button;
var jindu = 0;
self.is_loading = true;
cc.loader.onProgress = function ( completedCount, totalCount, item ){
if(totalCount !== 0 && self.is_loading === true){
jindu = completedCount/totalCount;
}
loadbar.progress = jindu;
var number_jindu = parseInt(jindu*100);
loadtext.string = number_jindu+'%';
};
cc.loader.loadResAll("ziyuan", function (err, assets) {
self.onLoadComplete();
});
},
onLoadComplete:function(){
this.is_loading = false;
this.login_button.node.active=true;
this.loadbar.node.active=false;
this.loadtext.node.active=false;
cc.loader.onComplete = null;
//cc.vv.AudioAction.PlayBGM('bg_one.mp3');
