cocos creator

1. Uncaught ReferenceError: Global is not defined
   解决：从定义 Global 的场景运行。

2. web-view（内嵌小游戏）跳转小程序时提示 "wx.miniprogram undefined"
   解决：不要用 js 动态引入（document.createElement('script’)），应该直接把
   <script type="text/javascript" src="https://res.wx.qq.com/open/js/jweixin-1.3.2.js"></script>放到 html 文件中。

3. 九宫格是用来拉伸的

4. 用户脚本组件在非激活状态下也会执行

5. spine 动画左右翻转

node.scaleX = -1

5. 把 node1移动到 node2的位置

    public static moveN1toN2(node1: cc.Node, node2: cc.Node) {
        node1.position = node1.parent.convertToNodeSpaceAR(node2.parent.convertToWorldSpaceAR(node2.position))
    }

6. 取消带参数的计时器：
   （1）返回带名字的 function

   this.schedule(this.reading(p1, p2), 0.2);
    reading(arg1, arg2) {
        return function f(){
		…
                this.unschedule(f);
                …
        }
    }

（2）重新声明一个函数

    this.f = this.reading.bind(this, p1, p2);
    this.schedule(this.f, 0.2);
    reading(arg1, arg2) {
            …
            this.unschedule(this.f);
            …
    }

7. 自动播放声音资源
   解决：如果构建时勾选 MD5 Cache，需要转换资源路径：

	const that = this;
        const wxsdk= document.createElement('script');
        wxsdk.src ='//res.wx.qq.com/open/js/jweixin-1.2.0.js';
        document.body.appendChild(wxsdk);
        wxsdk.onload=function(){
            wx.config({
                debug: false,
                appId: '',
                timestamp: 1,
                nonceStr: '',
                signature: '',
                jsApiList: []
            })
            wx.ready(function () {
                const audio = document.createElement('audio');
                window.audio = audio;
                let audioSrc = that.AudioClip;
                if (cc.loader.md5Pipe) {
                    audioSrc = cc.loader.md5Pipe.transformURL(audioSrc);
                }
                if (audio.readyState === 0) {
                    audio.src = audioSrc;
                    audio.load();
                }
                const audioPlayStart = window.setInterval(() => {
                    if(audio.readyState === 4){
                        audio.play();
                        window.clearInterval(audioPlayStart);
                    }
                },200);
            })
        }
		
    //对于 resources 文件夹中的音频资源：
    playAudio: function (currentId) {
        const lesson = Global.lesson;
        const category = Global.category;
        const sort = Global.sort;
        const audioUrl = sort + '/' + category + '/' + lesson + '/audio/audio' + currentId;
        cc.loader.loadResDir(audioUrl, function (err, assets, urls) {
            console.log('assets[0]',assets[0])
            console.log('urls[0]',urls[0])
            let audioSrc = assets[0].nativeUrl;
            if (cc.loader.md5Pipe) {
                audioSrc = cc.loader.md5Pipe.transformURL(audioSrc);
            }
            audio.src = audioSrc;
            console.log('audio.src-gameWord',audio.src)
            audio.load();
            const audioPlayStart = window.setInterval(() => {
                console.log('readyState',audio.readyState)
                if(audio.readyState === 4){
                    audio.play();
                    window.clearInterval(audioPlayStart);
                }
            },200);
            // util.playAudio(assets[0]);
        });
    }
