Sel_CallFuncN cannot cast void to Sel_CallFuncN - cocos2d-x

Question

I'm trying to get an intro screen in my game. After a few seconds it should change to the game itself.
In the Init of my introscreen class, I try to make a sequence, but I'm getting the following error:
cannot cast from type void to member pointer type
'cocos2d::SEL_CallFuncN' (aka
'void(cocos2d::CCObject::*)(cocos2d::CCNode *)'
here's my code:
bool IntroScreen::init() {
if (!CCLayer::init()) {
return false;
}
cocos2d::CCSize screenSize = cocos2d::CCDirector::sharedDirector()->getWinSize();
cocos2d::CCSprite* logomarca = cocos2d::CCSprite::create("rayman_intro.png");
logomarca->setPosition(ccp(screenSize.width / 2, screenSize.height / 2));
this->addChild(logomarca, 1);
cocos2d::CCFiniteTimeAction *seq1 = cocos2d::CCSequence::create(cocos2d::CCDelayTime::create(3.0),
cocos2d::CCCallFuncN::create(this,
cocos2d::SEL_CallFuncN(cocos2d::CCDirector::sharedDirector()->replaceScene(Controller::scene())), NULL);
this->runAction(seq1);
return true;
}
What am I doing wrong?

Answer 1

You can use scheduler here instead of CCFiniteTimeAction like this..
this->scheduleOnce(schedule_selector(IntroScreen::replace), 3);
void IntroScreen::replace(CCObject* sender){
cocos2d::CCDirector::sharedDirector()->replaceScene(Controller::scene();
}
Also insert a statement "using namespace cocos2d;" at the top to avoid writing cocos2d:: everywhere.

Answer 2

in SEL_CallFuncN you should put pointer to function not the function
For example
cocos2d::SEL_CallFuncN(IntroScreen::replace)
In replace put the code you want to invoke, if you use CallFuncN your method should have in first parametr place for object, which run the function
void IntroScreen::replace(CCObject* sender){
cocos2d::CCDirector::sharedDirector()->replaceScene(Controller::scene();
}
