Cocos2d-X 声音菜单的打开和关闭

（1）头文件中

USING_NS_CC;

USING_NS_CC_EXT;

#include "SimpleAudioEngine.h"

using namespace CocosDenshion;

class LoginLayer:publicCCLayer

{

public:

    virtual bool init();

    SCENE_FUNC(LoginLayer);

    CREATE_FUNC(LoginLayer);

    //开关声音

    void SoundOnOffClick(CCObject *sender);

    bool isSoundOpen；

};

（2）实现文件中

bool LoginLayer::init()

{

    if(!CCLayer::init())

    {

        return false;

    }

    isSoundOpen=false;

   //添加声音按钮

    CCMenuItemImage *soundbtnOn=CCMenuItemImage::create("soundon.png","soundon.png");

    CCMenuItemImage *soundbtnOff=CCMenuItemImage::create("soundoff.png","soundoff.png");

    CCMenuItemToggle *toggle=CCMenuItemToggle::createWithTarget(this,menu_selector(LoginLayer::SoundOnOffClick),soundbtnOn,soundbtnOff,NULL);

    toggle->setPosition(CCPointMake(0,0));

    CCMenu *menu1=CCMenu::create(toggle,NULL);

    menu1->setPosition(ccp(50,50));

    this->addChild(menu1);

    SimpleAudioEngine::sharedEngine()->playBackgroundMusic("yinyue.mp3",true);

    return true;

}

//声音的开与关的实现

void LoginLayer::SoundOnOffClick(CCObject *sender)

{

    if(isSoundOpen)

    {

        SimpleAudioEngine::sharedEngine()->resumeBackgroundMusic();

        isSoundOpen=false;

    }

    else

    {

        SimpleAudioEngine::sharedEngine()->pauseBackgroundMusic();

        isSoundOpen=true;

    }

}
