飞机大战第九节报错
我是按照视频打的但是不知道为什么貌似每个控件(按钮 label)都是"空的" 一访问就报出异常

我查了layaUI.max.all.js文件里面的组件名正确

 layaUI.max.all.js:
         this.pauseBtn=null;
         this.hpLabel=null;
         this.levelLabel=null;
         this.scoreLabel=null;
         this.infoLabel=null;


GameInfo.js:
var GameInfo = (function (_super) {
    function GameInfo() {
        GameInfo.super(this);
        // this.infoLabel.text = "abc"; 这个也报异常应该是找不到infoLabel
        // 注册按钮点击事件 点击后暂停游戏
        this.pauseBtn.on(Laya.Event.CLICK, this, this.onPauseBtnClick);
        // 初始化UI 显示
        this.reset();
    }

...
