cocos2d-x 播放音乐和音效

首先在头文件里添加：

#include "SimpleAudioEngine.h"

然后就可以调用如下函数来初始化和播放音乐：

//预加载背景音乐

CocosDenshion::SimpleAudioEngine::sharedEngine()->preloadBackgroundMusic( "Sound/SpaceGame.wav" );

//播放背景音乐

CocosDenshion::SimpleAudioEngine::sharedEngine()->playBackgroundMusic("Sound/SpaceGame.wav");

//预加载音效

CocosDenshion::SimpleAudioEngine::sharedEngine()->preloadEffect("Sound/explosion_large.mp3");

//播放音效

CocosDenshion::SimpleAudioEngine::sharedEngine()->playEffect("Sound/explosion_large.mp3");
