Question

This is my code I don\'t know how to create splash screen and how it will direct in my menu screen. All .h must be connected to BaseScreen and the BaseScreen will be the one

Here are three steps to add a splash screen scene on android. Using cocos2d-x 3.4. Hope this helps!

1 Create a SplashScene.cpp

    #include "SplashScene.h"
    #include "HomeScene.h"

    using namespace cocos2d;

    cocos2d::Scene* SplashScene::createScene()
    {
        // 'scene' is an autorelease object
        auto scene = Scene::create();

        // 'layer' is an autorelease object
        auto layer = SplashScene::create();

        // add layer as a child to scene
        scene->addChild(layer);

        // return the scene
        return scene;
    }



// on "init" you need to initialize your instance
bool SplashScene::init()
{
    if ( !Layer::init() )
    {
        return false;
    }

    auto visibleSize = Director::getInstance()->getVisibleSize();

    auto sprite = Sprite::create("splash.png");

    // position the sprite on the center of the screen
    sprite->setPosition(Vec2(visibleSize.width/2 , visibleSize.height/2 ));

    // add the sprite as a child to this layer
    this->addChild(sprite, 0);

    return true;
}

void SplashScene::onEnter() {
    Layer::onEnter();

    // Wait for 0.5 seconds to load main scene
    this->scheduleOnce(schedule_selector(SplashScene::finishSplash), 0.5f);
}

void SplashScene::finishSplash(float dt) {
    // ... do whatever other initializations here
    // Show the actual main scene
    Director::getInstance()->replaceScene(HomeScene::createScene());
}

2 Create SplashScene.h

#ifndef __SplashScene__
#define __SplashScene__

#include 
#include "cocos2d.h"

USING_NS_CC;

class SplashScene : public cocos2d::Layer
{
public:
    // there's no 'id' in cpp, so we recommend returning the class instance pointer
    static Scene* createScene();

    // Here's a difference. Method 'init' in cocos2d-x returns bool, instead of returning 'id' in cocos2d-iphone
    virtual bool init();

    void onEnter();

    void finishSplash(float dt);

    // implement the "static create()" method manually
    CREATE_FUNC(SplashScene);
};

#endif /* defined(__stickerPuzzle__SplashScene__) */

3 Modify AppDelegate.cpp

bool AppDelegate::applicationDidFinishLaunching() {
    // initialize director
    auto director = Director::getInstance();
    auto glview = director->getOpenGLView();
    if(!glview) {
        glview = GLViewImpl::create("My Game");
        director->setOpenGLView(glview);
    }

    // set FPS. the default value is 1.0/60 if you don't call this
    director->setAnimationInterval(1.0 / 60);

    // ... other stuff ... 

#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)
    // On Android - start the splash scene first
    auto scene = SplashScene::createScene(); 
    director->runWithScene(scene);
#endif

#if (CC_TARGET_PLATFORM == CC_PLATFORM_IOS)
    // On iOS, no need to add splash scene, start main scene directly
    auto scene = HomeScene::createScene(); 
    director->runWithScene(scene);
#endif

    return true;
}
