cocos2d-html5 各平台声音播放总结

2016-03-12 16:58 351 查看
cocos2d-js 采用官方的CocosDesion播放声音

声音资源一部分是mp3,一部分ogg

PC端,谷歌浏览器,播放声音一切正常,但到手机浏览器上声音就不能正常播放了

根据官方文档的音乐支持格式

平台支持的常见文件格式备注
Androidmp3, mid, oggg, wav可以播放android.media.MediaPlayer所支持的所有格式
iOSaac, caf, mp3, m4a, wav可以播放AVAudioPlayer所支持的所有格式
Windowsmid, mp3, wav
CocosDesion支持的音效格式如下:
平台支持的常见文件格式备注
Androidoggg, wav对wav的支持不完美
iOScaf, m4a可以播放Cocos2d-iPhone CocosDesion所支持的所有格式
Windowsmid, wav
主要原因是各平台格式不一样导致了不能播放
对比了一下音乐格式,主要采用ogg作为主要格式,其他格式作为扩展

 mp3 :体积小,音质好

 ogg :体积小,免费,音质好

 wav:无压缩、体积大

写了个测试程序

var HelloWorldLayer = cc.Layer.extend({
sprite:null,
_userCursor:null,
ctor:function () {
this._super();
var size = cc.winSize;

this.musicDirectory = new Array();
for(var i in music_res)
{
this.musicDirectory.push(music_res[i])
}
this.curMusicIndex = 0;
this.soundDirectory = new Array();
for(var i in sound_res)
{
this.soundDirectory.push(sound_res[i]);
}
this.curSoundIndex = 0;

var curMusic = new cc.LabelTTF("当前播放音乐:"+this.musicDirectory[this.curMusicIndex].substr(16), "微软雅黑", 20);
curMusic.x = cc.winSize.width / 2;
curMusic.y = cc.winSize.height / 2 + 150;
this.addChild(curMusic);
this.m_curMusicLabel = curMusic;

var playMusic = new cc.LabelTTF("播放", "微软雅黑", 18);
var playMusicItem = new cc.MenuItemLabel(playMusic, this.playMusicCallback, this);

return true;

this.m_curSoundLabel.setString("播放音效停止");
}
});结果是,除了ios端有一个ogg播放不了,这个音乐播放小程序在各个平台ogg都能正常播放。
但放到我的游戏项目中结果又不一样了

----PC浏览器,音乐音效采用ogg可以正常播放

----安卓端浏览器,音乐音效采用ogg可以正常播放

----IOS端浏览器,音乐无法播放ogg,可以播放mp3, 音效无法播放ogg和mp3,可以播放wav

不过cocosdension如果一种格式不能播放会自动搜寻其他格式,所以背景音乐同目录下放了ogg和mp3两种格式,音效则放了ogg和wav格式,

不能播放问题就解决了,

播放延迟卡顿问题:

    如果你的音乐音效没有预加载,第一次播放音乐音效会有延迟,如果文件较大延迟会比较厉害,可以将资源路径添加到预加载目录,预加载避免延迟

    不过预加载会明显影响游戏加载速度,可能会导致画面卡住,如何取舍看个人了。

ios端浏览器第一次进场景加载音乐不能播放问题:

    原因是因为苹果的移动端浏览器不能自动播放音频,只能由用户的触摸(点击)事件触发加载,进游戏时音乐没有播放,苹果定的规则只能遵守了

    我的办法是在第一个场景做下判断,如果是手机端的ios浏览器,创建一个顶层的Layer,并添加事件,在触发onTouchBegan时playMusic就行了。

if(cc.sys.isMobile && cc.sys.os === cc.sys.OS_IOS)
{
var musicStartLayer = new cc.Layer();
musicStartLayer.x = 0;
musicStartLayer.y = 0;
this.addChild(musicStartLayer);

var listener = cc.EventListener.create({
event: cc.EventListener.TOUCH_ONE_BY_ONE,
swallowTouches: false,
onTouchBegan: function(touch, event){
if(!self.isFirstTouch)
{
self.isFirstTouch = true;
cc.audioEngine.playMusic("res/music.ogg");
}
return true;
}
});
cc.eventManager.addListener(listener, musicStartLayer);
}
