cocos2dx 菜鸟进阶篇（一） 在游戏中添加music

本来是打算继续写《学习篇》的，可一想，都快过年了，新年新气象嘛，要不换个章篇继续high？说干就干！

从学习篇到进阶篇，虽然还是菜鸟，但是菜鸟确实也在进步着！

这篇就讲在游戏中添加背景音乐跟音效。其实这个在-x 的testcpp 的cocosDenshionTest 里都写的很详细。

一：在.cpp中添加头文件

//cpp with cocos2d-x

#include"SimpleAudioEngine.h" 

二：在init()里添加背景音乐

//cpp with cocos2d-x

CocosDenshion::SimpleAudioEngine::sharedEngine()->playBackgroundMusic(

"background-music-aac.wav",true); 

三：添加特效：

//cpp with cocos2d-x

CocosDenshion::SimpleAudioEngine::sharedEngine()->playEffect(

"pew-pew-lei.wav"); 

四：还有一些其他操作，包括pause，stop等：

backGround：

 // stop background music
    case 1:
        SimpleAudioEngine::sharedEngine()->stopBackgroundMusic();
        break;
    // pause background music
    case 2:
        SimpleAudioEngine::sharedEngine()->pauseBackgroundMusic();
        break;
    // resume background music
    case 3:
        SimpleAudioEngine::sharedEngine()->resumeBackgroundMusic();
        break;
    // rewind background music
    case 4:
        SimpleAudioEngine::sharedEngine()->rewindBackgroundMusic();
        break;

Effect：
   

 // stop effect
    case 8:
        SimpleAudioEngine::sharedEngine()->stopEffect(m_nSoundId);
        break;
    // unload effect
    case 9:
        SimpleAudioEngine::sharedEngine()->unloadEffect(std::string(CCFileUtils::sharedFileUtils()->fullPathFromRelativePath(EFFECT_FILE)).c_str());
        break;
        // add bakcground music volume
    case 10:
        SimpleAudioEngine::sharedEngine()->setBackgroundMusicVolume(SimpleAudioEngine::sharedEngine()->getBackgroundMusicVolume() + 0.1f);
        break;
        // sub backgroud music volume
    case 11:
        SimpleAudioEngine::sharedEngine()->setBackgroundMusicVolume(SimpleAudioEngine::sharedEngine()->getBackgroundMusicVolume() - 0.1f);
        break;
        // add effects volume
    case 12:
        SimpleAudioEngine::sharedEngine()->setEffectsVolume(SimpleAudioEngine::sharedEngine()->getEffectsVolume() + 0.1f);
        break;
        // sub effects volume
    case 13:
        SimpleAudioEngine::sharedEngine()->setEffectsVolume(SimpleAudioEngine::sharedEngine()->getEffectsVolume() - 0.1f);
        break;
    case 14:
        SimpleAudioEngine::sharedEngine()->pauseEffect(m_nSoundId);
        break;
    case 15:
        SimpleAudioEngine::sharedEngine()->resumeEffect(m_nSoundId);
        break;
    case 16:
        SimpleAudioEngine::sharedEngine()->pauseAllEffects();
        break;
    case 17:
        SimpleAudioEngine::sharedEngine()->resumeAllEffects();
        break;
    case 18:
        SimpleAudioEngine::sharedEngine()->stopAllEffects();

五：注意！

1、音乐格式要注意，像在pc机上wav，mp3是可以用的，ogg那是肯定不可以的。

2、开始播放音乐后，即使你切换场景，音乐还是在播放。所以需要在切换场景的同时把音乐关上。
