js 创建进度条

  //添加进度条背景    var slide_bg=new cc.Sprite(res.slide1);    this.addChild(slide_bg,30);    slide_bg.setPosition(cc.winSize.width/2,cc.winSize.height*0.03);    //添加进度条    slide=new ccui.LoadingBar(res.slide2);    slide.setPercent(50);    this.addChild(slide,30);    slide.setPosition(slide_bg.getPosition());    this.schedule(this.onReducingBonus,0.1);},onReducingBonus:function(){    slide.setPercent(slide.getPercent()+0.2);    if(slide.getPercent()==100){        this.unschedule(this.onReducingBonus);            }

记得要用ccui.，，我刚开始用的cc.，，报错
