利用cocos2dx 3.2開發消滅星星（十）爲遊戲添加音效（項目源碼分享）

一個遊戲，聲音也是非常的重要，其實cocos2dx裏面的簡單音效引擎的使用是非常簡單的。我這裏只不過是用一個類對所有的音效進行管理罷了。

Audio.h

#ifndef _AUDIO_H_
#define _AUDIO_H_
class Audio{
public:
	static Audio* getInstance();
	void playBGM();
	void playReadyGo();
	void playPop();
	void prepare();
	void playCombo(int size);
private:
	static Audio* m_instance;
};
#endif

Audio.cpp

#include "Audio.h"
#include "SimpleAudioEngine.h"
Audio* Audio::m_instance = nullptr;
Audio* Audio::getInstance(){
	if(m_instance == nullptr){
		m_instance = new Audio();
	}
	return m_instance;
}

void Audio::playBGM(){
	CocosDenshion::SimpleAudioEngine::getInstance()->playBackgroundMusic("Music/music.ogg",true);
}

void Audio::playReadyGo(){
	CocosDenshion::SimpleAudioEngine::getInstance()->playEffect("Music/readygo.ogg",false);
}

void Audio::playPop(){
	CocosDenshion::SimpleAudioEngine::getInstance()->playEffect("Music/pop.ogg",false);
}

void Audio::playCombo(int size){
	if(size < 5)
		return;
	if(size >= 10){
		CocosDenshion::SimpleAudioEngine::getInstance()->playEffect("Music/combo_3.ogg",false);
	}else if(size >= 7){
		CocosDenshion::SimpleAudioEngine::getInstance()->playEffect("Music/combo_2.ogg",false);
	}else {
		CocosDenshion::SimpleAudioEngine::getInstance()->playEffect("Music/combo_1.ogg",false);
	}
}
void Audio::prepare(){
	CocosDenshion::SimpleAudioEngine::getInstance()->preloadBackgroundMusic("Music/music.ogg");
	CocosDenshion::SimpleAudioEngine::getInstance()->preloadEffect("Music/readygo.ogg");
	CocosDenshion::SimpleAudioEngine::getInstance()->preloadEffect("Music/pop.ogg");
	CocosDenshion::SimpleAudioEngine::getInstance()->preloadEffect("Music/combo_1.ogg");
	CocosDenshion::SimpleAudioEngine::getInstance()->preloadEffect("Music/combo_2.ogg");
	CocosDenshion::SimpleAudioEngine::getInstance()->preloadEffect("Music/combo_3.ogg");
}

好了，本系列教程到此結束，第一次寫教程如有不對請見諒或指教，謝謝大家。
