Cocos2d-x又一種背景音樂設定方法

設定按鈕

點一下ON切換到OFF，點一下OFF切換到ON，實現：

建立功能表按鈕

setimage = CCMenuItemImage::create("sound-on-A.png", "sound-off-A.png", this, menu_selector(Game::SetMusic));setimage->setScale(0.5f);setimage->setPosition(ccp(size.width-20,  size.height-20));MUISC = false;CCMenu *menu2 = CCMenu::create(setimage, NULL);menu2->setPosition(CCPointZero);this->addChild(menu2);

按鈕回呼函數：

void Game::SetMusic(CCObject* Object){if (!MUISC)//禁音 ,off表徵圖顯示{setimage->setNormalImage(CCSprite::create("sound-off-A.png"));//off可用setimage->setDisabledImage(CCSprite::create("sound-on-A.png"));//on不可用CocosDenshion::SimpleAudioEngine::sharedEngine()->stopBackgroundMusic();MUISC = true;CCLOG("stop...");}else//開啟, on表徵圖顯示{setimage->setNormalImage(CCSprite::create("sound-on-A.png"));//on可用setimage->setDisabledImage(CCSprite::create("sound-off-A.png"));//off不可用CocosDenshion::SimpleAudioEngine::sharedEngine()->playBackgroundMusic("MainMenu.mp3", true);MUISC = false;CCLOG("start...");}}
