cocos 播放配音

首先一个配音id集合的json文件，AudioConfig.json：

 1 [
 2     {"id":1,"path":"bgm/menuBgm"},
 3     {"id":2,"path":"bgm/BGM_001"},
 4     {"id":3,"path":"bgm/BGM_002"},
 5     {"id":4,"path":"bgm/BGM_003"},
 6     {"id":5,"path":"bgm/BGM_004"},
 7     {"id":6,"path":"bgm/BGM_005"},
 8     {"id":7,"path":"bgm/BGM_006"},
 9     {"id":8,"path":"bgm/BGM_007"},
10     {"id":9,"path":"bgm/Annie_hello"},
11     {"id":10,"path":"bgm/Timmy_Hi_Annie_How_are_you_today"}
12 ]

json文件加载处理，配音调用类PlaySound类：

 1 cc.Class({
 2     extends: cc.Component,
 3 
 4     properties: {
 5         _musicVolume: 1.0,
 6         _playEffect: [],
 7         _switchEffect: true
 8     },
 9 
10     onLoad () {
11         cc.loader.load(cc.url.raw(‘resources/AudioConfig.json‘), (err,object) => {
12 
13             if (err) {
14                 cc.log(err);
15             }
16             else{
17                 cc.log("我有数据啦");
18                 var list = object;
19 
20                 var nlength = list.length;
21                 // cc.log("nlength = " + nlength);
22                 this.Arr = new Array(nlength);
23                 for (let i=0;i<nlength;i++)
24                 {
25                     var arrvalue = list[i];
26                     // 把数组当字典使用
27                     this.Arr[arrvalue.id] = arrvalue.path;
28                 }
29 
30 
31             }
32         });
33     },
34 
35 
36     start () {
37 
38     },
39 
40     PlaySoundId: function(id) {
41         var _url = "audio/" + this.Arr[id];
42         // cc.log("PlaySoundId将要获取的id对应路径：" + str);
43         // loadRes 不要.mp3后缀名，如果有后缀名则警告
44         cc.loader.loadRes(_url, (err, asset)=> {
45             this.playEffect(_url);
46         });
47     },
48 
49     playEffect: function(url){
50         if(this._switchEffect){
51             var rawUrl = cc.url.raw("resources/" + url);
52             cc.log("resources/"+url);
53            
54             // getRes 要.mp3后缀名，否则要报警告
55             if(cc.loader.getRes(rawUrl+".mp3")){
56                 var effectId = cc.audioEngine.playEffect(rawUrl+".mp3", false, this._musicVolume);
57                 this._playEffect[url] = effectId;
58                 cc.log("声音播放");
59             }
60             else{
61                 cc.log("【音频】音效" + url + "文件不存在");
62             }
63         }
64 
65 
66     },
67     // update (dt) {},
68 });

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。
