Why don’t you just create a simple function to do the stuff? Instead of this:

CallFunc* removeSprite = CallFunc::create(CC_CALLBACK_0(HelloWorld::removeFunc,this));

use:

removeFunc(int value);

Right on @barabasandras1

The reason why I did not just simply create a function for use is because I have no choice.

For example, I need to play several particle effects and then delete the particles.

The original function will automatically delete it, but it did not work. I suppose it is because I always display particle effect more than twice within single click, and as long as I create a new particle, the old pointer will redirect to the new particle and make memory leak. So I have to do a sequence action. Create it and delete it. However, both creating and deleting are not an action. I cannot use sequence to control their running timeline.(If they run together the particle effect will disappear immediately after creating.)

Thus, I use CallFunc to implement creating and deleting so that I can use a simple sequence to do such things without memory leaking.

For another example:

void GameLayer::showLinkNum(int size)
{
	Size visibleSize = Director::getInstance()->getVisibleSize();
	string s;
	if (Global::isDoubled) s = "+" + String::createWithFormat("%d", size * size * 10)->_string;//String->_string: convert cocos2d::String to std::string
	else s= "+" + String::createWithFormat("%d", size * size * 5)->_string;
	linkNum->setString(s);
	linkNum->setVisible(true);
	linkNum->setScale(1.0f);
	
	linkNum->setPosition(touchPos);
	auto flyup = MoveTo::create(1.8f, Point(visibleSize.width / 2 + origin.x, visibleSize.height * 0.9 + origin.y));
	auto shrink = ScaleTo::create(1.8f, 0.8f);
	CallFunc* invisible = CallFunc::create(CC_CALLBACK_0(GameLayer::hideLinkNum,this));

	Sequence* seq = Sequence::create(Spawn::create(flyup, shrink, NULL), invisible/*,refreshScoreF*/, NULL);
	linkNum->runAction(seq);
}

This is an effect that displays words and flies up.

I cannot let the word be invisible as long as it is still flying.

I need to wait until the animation is done.

In such case, I cannot just use simple function to do what I need to.

Got just the thing for you

use the Callfunc action, you can check it out on our Cocos API Guide http://cocos.sonarlearning.co.uk/v1.0/docs/actions

You can use it like any other action, even in a sequence :D

Thank you for the reply. But sadly this is not what I need exactly.

I think I need the example of CallFuncN and CC_CALLBACK_1、CC_CALLBACK_2, etc.

Still appreciate your effort!

Whats wrong with the CallFuncN method

I don’t think I really understand CallFuncN because I never succeed using it.

Would you mind illustrating it with a simple example, please?

Thank you.

From the link I gave you, put that CallFuncN action inside a sequence, repeat, anywhere you would put another action such as the MoveTo

For example,

//ShopMenu.cpp
auto closebtn = MenuItemImage::create("close.png", "close.png", CC_CALLBACK_1(ShopMenu::closeLayer, node));

ps. node is this pointer in GameLayer.

void ShopMenu::closeLayer(Layer* shopLayer)
{
	shopLayer->removeFromParentAndCleanup(true);
}

How do I send shoplayer into closeLayer() and let the layer be deleted?

I don’t understand?

I apologize for my pathetic English.

What I mean is that I need to design a menu button, but somehow I do not know how to pass parameters in CC_CALLBACK_N. I succeed creating a menu button only if the function is really simple and does not  have parameters.

I need a simple tutorial. Thanks.

Thank you! It really helps.

Great to hear :D
