跨平台类的写法

跨平台类的写法

有如下代码

void AudioEngine::playMusic(const std::string& fileName,bool bLoop /* = false */){stopMusic();if (m_bgmEnabled){#if (TARGET_PLATFORM == PLATFORM_WIN32)AudioEngineWin::playBackgroundMusic(fileName.c_str(),bLoop);#elif (TARGET_PLATFORM == PLATFORM_ANDROID)AudioEngineAndroid::playBackgroundMusic(fileName.c_str(),bLoop);#elif (TARGET_PLATFORM == PLATFORM_IOS)AudioEngineIos::playBackgroundMusic(fileName.c_str(),bLoop);#endif}}

实际上的写法应是

void AudioEngine::playMusic(const std::string& fileName,bool bLoop /* = false */){stopMusic();if (m_bgmEnabled){AudioEngineCore::playBackgroundMusic(fileName.c_str(),bLoop);}}

在编译过程中根据不同平台，指定相应的cpp
