6

This is what i use:

SplashScene.h

#pragma once

#include "cocos2d.h"

class SplashScene : public cocos2d::LayerColor
{
public:
    static cocos2d::Scene* createScene();

    virtual bool init();

    CREATE_FUNC(SplashScene);
private:
    void LoginRegisterScene(float dt);
};

SplashScene.cpp

#include "SplashScene.h"
#include "LoginRegisterScene.h"

USING_NS_CC;

Scene* SplashScene::createScene()
{
    auto scene = Scene::create();

    auto layer = SplashScene::create();

    scene->addChild(layer);

    return scene;
}

bool SplashScene::init()
{
    if ( !LayerColor::initWithColor(Color4B(255, 255, 255, 255)) )
    {
        return false;
    }

    ........
    this->scheduleOnce(schedule_selector(SplashScene::LoginRegisterScene), 3); // after 3 seconds, go to LoginRegisterScene

    return true;
}

void SplashScene::LoginRegisterScene(float dt){
        auto scene = LoginRegisterScene::createScene();
        Director::getInstance()->replaceScene(TransitionSlideInR::create(0.25f, scene)); // transition time of the scene
}
