由于simpleAu@R_404_410@Engine在播放音效时无法获取状态也无法在播放完成后回调，造成音效在按键频繁时发声重叠。改mac版本的库对目前的我来说挑战难度太大。
于是百度了半天，发现3.6版本的cocos2dx有了新的声音播放库Au@R_404_410@Engine。于是体验下，感觉还不错：
直接贴代码：
头文件：
#ifndef __macstudycocos2dx__newAu@R_404_410@EngineTest__
#define __macstudycocos2dx__newAu@R_404_410@EngineTest__
#include <st@R_404_410@.h>
#include "cocos2d.h"

public:
staticcocos2d::Scene* createScene();
virtualbool init();
// a selector callback
void playCallback(cocos2d::Ref* pSender);//点击按钮后开始播放的回调函数
CREATE_FUNC(newAu@R_404_410@EngineTest);
bool isplaying=false;//标记播放状态
void changer_playingstatus();//播放完成后的回调函数，用来更改播放状态
};
newAu@R_404_410@EngineTest.cpp如下：
#endif /* defined(__macstudycocos2dx__newAu@R_404_410@EngineTest__) */

auto scene =Scene::create();
// 'layer' is an autorelease object
auto layer =newAu@R_404_410@EngineTest::create();
// add layer as a child to scene

// return the scene
return scene;
}

{

return false;
}
Size visibleSize =Director::getInstance()->getVisibleSize();
Vec2 origin =Director::getInstance()->getVisibleOrigin();
auto menuitem=MenuItemFont::create("play wav",CC_CALLBACK_1(newAu@R_404_410@EngineTest::playCallback,this));
menuitem->setPosition(Vec2(0,0));
// create menu,it's an autorelease object
auto menu =Menu::create(menuitem,NULL);
menu->setPosition(Vec2(visibleSize.width/2,visibleSize.height/2));
this->addChild(menu,1);
return true;
}
voidnewAu@R_404_410@EngineTest::playCallback(Ref* pSender)
{
if (!isplaying) {
log("wav is not playing!");
isplaying=true;
int au@R_404_410@ID=play2d("man1.wav");//播放音效文件
log("au@R_404_410@ID =%d",au@R_404_410@ID);
setFinishCallback(au@R_404_410@ID,CC_CALLBACK_0(newAu@R_404_410@EngineTest::changer_playingstatus,0); font-size:11px"> //音效播放完成后修改播放状态，此时会用到au@R_404_410@ID
}
else{
log("wav is playing,this click is not response!");
}
}
voidnewAu@R_404_410@EngineTest::changer_playingstatus(){
isplaying=false;
log("finished,status has been change");
}
以下是log输出：（可以看出au@R_404_410@ID是改变的，即使播放同一个音效）

起初觉得如果音效可以使用Au@R_404_410@Engine来做，记住要用caf和wav格式。背景音乐可以使用simpleAu@R_404_410@Engine来播放，毕竟simpleAu@R_404_410@Engine有缓存机制。
更正下，之所以标红，是今天发现如果同时使用Au@R_404_410@Engine和simpleAu@R_404_410@Engine时会导致音效无法播放，具体原因不清楚。看来只能使用Au@R_404_410@Engine了。
Au@R_404_410@Engine中没有了playbackgoudmuisc的方法，背景音乐通过play2d来播放，通过Au@R_404_410@ID可以对背景音乐的播放进行控制，用起来也很方便。
而且，今天发现Au@R_404_410@Engine能播放mp3格式的音乐文件，对于被wav撑得硕大的app来说使用mp3格式无疑是个完美的解决方案，真机的调试效果也是相当满意。
（未完待续）
如果不继承类时可以使用以下方式来播放哦：
int au@R_404_410@ID=experimental::Au@R_404_410@Engine::play2d(wavfilestring->getCString());
