cocos 播放配音

首先一个配音id集合的json文件，AudioConfig.json：

[
    {"id":1,"path":"bgm/menuBgm"},
    {"id":2,"path":"bgm/BGM_001"},
    {"id":3,"path":"bgm/BGM_002"},
    {"id":4,"path":"bgm/BGM_003"},
    {"id":5,"path":"bgm/BGM_004"},
    {"id":6,"path":"bgm/BGM_005"},
    {"id":7,"path":"bgm/BGM_006"},
    {"id":8,"path":"bgm/BGM_007"},
    {"id":9,"path":"bgm/Annie_hello"},
    {"id":10,"path":"bgm/Timmy_Hi_Annie_How_are_you_today"}
]

json文件加载处理，配音调用类PlaySound类：

cc.Class({
    extends: cc.Component,

    properties: {
        _musicVolume: 1.0,
        _playEffect: [],
        _switchEffect: true
    },

    onLoad () {
        cc.loader.load(cc.url.raw('resources/AudioConfig.json'), (err,object) => {

            if (err) {
                cc.log(err);
            }
            else{
                cc.log("我有数据啦");
                var list = object;

                var nlength = list.length;
                // cc.log("nlength = " + nlength);
                this.Arr = new Array(nlength);
                for (let i=0;i<nlength;i++)
                {
                    var arrvalue = list[i];
                    // 把数组当字典使用
                    this.Arr[arrvalue.id] = arrvalue.path;
                }


            }
        });
    },


    start () {

    },

    PlaySoundId: function(id) {
        var _url = "audio/" + this.Arr[id];
        // cc.log("PlaySoundId将要获取的id对应路径：" + str);
        // loadRes 不要.mp3后缀名，如果有后缀名则警告
        cc.loader.loadRes(_url, (err, asset)=> {
            this.playEffect(_url);
        });
    },

    playEffect: function(url){
        if(this._switchEffect){
            var rawUrl = cc.url.raw("resources/" + url);
            cc.log("resources/"+url);
           
            // getRes 要.mp3后缀名，否则要报警告
            if(cc.loader.getRes(rawUrl+".mp3")){
                var effectId = cc.audioEngine.playEffect(rawUrl+".mp3", false, this._musicVolume);
                this._playEffect[url] = effectId;
                cc.log("声音播放");
            }
            else{
                cc.log("【音频】音效" + url + "文件不存在");
            }
        }


    },
    // update (dt) {},
});

配音文件在初始化时，既已调用，要把脚本添加到要添加的节点上，推荐添加到根节点，通过这个节点，进行一次加载即可在其他需要播放声音的时候，直接调用即可。
