接着看教程:播放音乐与音效,然后想实现一个播放,暂停,停止的小功能,就附加看了一下Menu的一些知识,又回顾了一下坐标系
音乐和音效的播放主要使用的SimpleAudioEngine,目前看3.x里面SimpleAudioEngine的注释没有说depart,所以应该和2.x是一直的。
1、先导入头文件和命名空间
#include <SimpleAudioEngine.h> using namespace CocosDenshion;
2、SimpleAudioEngine::getInstance()初始化AudioEngine,在Scene的init中调用
SimpleAudioEngine::getInstance()->preloadBackgroundMusic(BG_MUSIC); SimpleAudioEngine::getInstance()->preloadEffect(DOG_WANGWANG);
预加载音频文件
SimpleAudioEngine::getInstance()->playBackgroundMusic(BG_MUSIC,true); dog_wangwang = SimpleAudioEngine::getInstance()->playEffect(DOG_WANGWANG); SimpleAudioEngine::getInstance()->resumeBackgroundMusic(); SimpleAudioEngine::getInstance()->resumeEffect(dog_wangwang); if (SimpleAudioEngine::getInstance()->isBackgroundMusicPlaying()){ SimpleAudioEngine::getInstance()->pauseBackgroundMusic(); } if (dog_wangwang > 0){ SimpleAudioEngine::getInstance()->pauseEffect(dog_wangwang); } SimpleAudioEngine::getInstance()->stopBackgroundMusic(true); SimpleAudioEngine::getInstance()->stopAllEffects();还有一些方法,可以查看定义。
Menu继承关系如图:
简单使用
auto playBgMusic = MenuItemFont::create("Paly BgMusic",CC_CALLBACK_1(HelloWorld::menuPlayBgMusicCallback,this)); playBgMusic->setPosition(Vec2(visibleSize.width / 5,visibleSize.height / 6)); // create menu,it's an autorelease object auto menu = Menu::create(closeItem,playBgMusic,playEffect,pause,resume,stop,NULL); menu->setPosition(Vec2::ZERO); this->addChild(menu,1); void HelloWorld::menuPlayBgMusicCallback(Ref* pSender){ SimpleAudioEngine::getInstance()->playBackgroundMusic(BG_MUSIC,true); }
