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

Answer 1

try this link out maybe you can find something useful here http://www.androidhive.info/2013/07/how-to-implement-android-splash-screen-2/

#include "HelloWorldScene.h" 
#include "OptionsScene.h" 
#include "SplashScene.h" 
#include "SimpleAudioEngine.h" 
#include "RedirectMethods.h" 

using namespace cocos2d;
using namespace CocosDenshion;

CCScene* SplashScene::scene() {
    CCScene *scene = CCScene::create();
    SplashScene *layer = SplashScene::create();
    scene->addChild(layer);
    return scene;
}

bool SplashScene::init() {
    if (!CCLayer::init()) {
        return false;
    }

    CCSize screenSize = CCDirector::sharedDirector()->getWinSize();

    CCSprite* logomarca = CCSprite::create("cocos2dx_logo.png");
    logomarca->setPosition(ccp(screenSize.width / 2, screenSize.height / 2));
    this->addChild(logomarca, 1);

    CCFiniteTimeAction *seq1 = CCSequence::create(CCDelayTime::create(3.0),
            CCCallFuncN::create(this,
                    callfuncN_selector(RedirectMethods::MenuScene)), NULL);

    this->runAction(seq1);

    return true;
}

or try this one i hope it will solve it

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 <stdio.h>
#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;
}

Answer 3

I am using the scheduleOnce function.

void Splash::onEnter(){
    CCLayer::onEnter();
    CCLog("onEnter");
    this->scheduleOnce(schedule_selector(Splash::finishSplash),2.0f);
}

void Splash::finishSplash(float dt){
    CCDirector::sharedDirector()->replaceScene(GameWall::scene());
}

after 2 seconds, finish the splash screen and start GameWall Screen. That's all I have done.

You can make class inherit from CCLayer which start your applications and display your sprite. Then you can override onEnterTransitionDidFinish method:

 void SplashScreen::onEnterTransitionDidFinish(){
  CCScene * sceneAfterSplashScreen = StartLayer::scene();
  CCDirector::sharedDirector()->replaceScene(sceneAfterSplashScreen);
}

When the splash screen arrived to the screen, then it's start to load new scene and replace it.
