代码实例：

bool HelloWorld::init(){    //////////////////////////////    // 1. super init first    if ( !Layer::init() )    {        return false;    }        Size visibleSize = Director::getInstance()->getVisibleSize();    Vec2 origin = Director::getInstance()->getVisibleOrigin();// 创建精灵类auto sprite = Sprite::create("taotaoahui.jpg");//sprite->setPosition(ccp(visibleSize.width / 2, visibleSize.height / 2));sprite->setAnchorPoint(ccp(0,0));addChild(sprite,1);   // ParticleBatchNode 使用方法， auto _emitter = ParticleSystemQuad::create("Particles/taotao.xml.particle.plist");// 首先创建ParticleSystemQuad或者ParticleSystem _emitter->retain(); auto batch = ParticleBatchNode::createWithTexture(_emitter->getTexture()); batch->addChild(_emitter); batch->setPosition(ccp(visibleSize.width /2 , visibleSize.height /2 ));// sjt this->addChild(batch, 10);        return true;}
