cocos2dx 音效 粒子 数据存储

1.音效

引入头文件

#include "simpleAudioEngine.h"

命名空间

using namespace CocosDenshion;

//创建一个背景
    Size winSize = Director::getInstance()->getWinSize();
    spriteTest = Sprite::create("bg.png");
    spriteTest->setPosition(Vec2(winSize.width/2,winSize.height/2));
    this->addChild(spriteTest);
   
    //
    MenuItemSprite *itemSprite = MenuItemSprite::create(Sprite::create("1.png"), Sprite::create("8.png"), [&](Ref *spander){
        CCLOG("点击了按钮");
        //播放音效
        SimpleAudioEngine::getInstance()->playEffect("bg.mp3");
    });
    itemSprite->setPosition(Vec2(winSize.width/2,100));
    
    Menu *menu = Menu::create(itemSprite, NULL);
    menu->setPosition(Vec2());
    this->addChild(menu);
    
    //播放背景音乐
    SimpleAudioEngine::getInstance()->playBackgroundMusic("bg.mp3",true);
    return true;
    
    //提前加载音效(只加载不播放)
    SimpleAudioEngine::getInstance()->preloadEffect("bg.mp3");

2.粒子系统

有个particle design 工具自定义粒子效果

ParticleFire *ex = ParticleFire::create();
ex->setPosition(Vec2(320, 240));
 this->addChild(ex);

3.数据存储

   //存储
    UserDefault::getInstance()->setIntegerForKey("hp", 123);
    UserDefault::getInstance()->flush();
    
    //获取
    int HP = UserDefault::getInstance()->getIntegerForKey("hp");
    CCLOG("HP=%d",HP);
