Hi there.

I want to create an effect like halo. My problem is that I will create a halo sprite everytime I click. I think it is not good.

Do I have better way to implement it?

Thanks.

	...

	EventListenerTouchOneByOne* listener = EventListenerTouchOneByOne::create();
	listener->onTouchBegan = CC_CALLBACK_2(HelloWorld::onTouchBegan, this);
	Director::getInstance()->getEventDispatcher()->addEventListenerWithSceneGraphPriority(listener, this);

	return true;
}

bool HelloWorld::onTouchBegan(Touch* touch, Event* event)
{
	Size visibleSize = Director::getInstance()->getVisibleSize();
	//halo->setOpacity(128);
	halo = Sprite::create("halo.png");
	Point p = touch->getLocationInView();
	p = Director::getInstance()->convertToGL(p);
	halo->setPosition(p.x, p.y);
	this->addChild(halo, 2);

	auto enlarger = ScaleBy::create(1.0f, 5.0f, 5.0f);
	//halo->runAction(enlarger);
	auto fadeout = FadeOut::create(1.0f);
	//halo->runAction(fadeout);

	halo->runAction(Spawn::create(enlarger, fadeout,NULL));
	

	return true;
}
