Create Splash screen in cocos 2d-x - cocos2d-x

Question

Hello I am creating an game in cocos2d-x and when I am scheduling an event on splash screen for run game .It shows compilation error (in expansion of macro 'schedule_selector')
Following is my code for this
Splash.h
#ifndef SPLASH_H_
#define SPLASH_H_
#include "cocos2d.h"
class CCSplashLayer : public cocos2d::CCLayer {
private :
void runGame();
public:
static cocos2d::CCScene* createScene();
virtual bool init();
CREATE_FUNC(CCSplashLayer);
};
#endif /* SPLASH_H_ */
And SplashScene.cpp
#include "splash.h"
#include "cocos2d.h"
#include "HelloWorldScene.h"
USING_NS_CC;
bool CCSplashLayer::init() {
if (!Layer::init()) {
return false;
}
Size visibleSize = Director::getInstance()->getVisibleSize();
auto sprite = Sprite::create("splash.png");
sprite->setScale(Director::getInstance()->getContentScaleFactor());
sprite->setPosition(Vec2(visibleSize.width / 2,visibleSize.height/2));
this->addChild(sprite, 0);
//This line cause problem show i symbol on this line in eclipse
this->scheduleOnce(schedule_selector(CCSplashLayer::runGame),4.0f);
return true;
}
Scene* CCSplashLayer::createScene() {
auto scene = CCScene::create();
auto layer = CCSplashLayer::create();
scene->addChild(layer);
return scene;
}
void CCSplashLayer::runGame(){
auto scene = HelloWorld::createScene();
Director::getInstance()->setDepthTest(true);
TransitionScene *transition = TransitionScene::create(0.5f, scene);
Director::getInstance()->pushScene(transition);
}

Answer 1

schedule_selector takes function pointer which needs a float argument for time.
Change method CCSplashLayer::runGame() to CCSplashLayer::runGame(float dt) in defination and declaration.
Also you are pushing a scene over splash scene, which is not recommended way for splash scene. You must replace splash scene with new scene because we never need to display splash again in game unless there is specific design requirement of game.

Answer 2

Try this macro:
#define CCDL_PERFORM_SELECTOR( __OWNER__, __DELAY__, __CALLFUNC_SELECTOR__ ) \
__OWNER__->runAction( cocos2d::Sequence::create( \
cocos2d::DelayTime::create( __DELAY__ ), \
cocos2d::CallFunc::create( CC_CALLBACK_0( __CALLFUNC_SELECTOR__,__OWNER__) ), \
nullptr )); \
(source: https://github.com/duksel/Cocos2dx-DukselLib/blob/master/Cocos2dx-DukselLib/DukselMacros.h#L70-L74)
Allow to use for any CCNode (+subclass) instance.
In your case will be:
bool CCSplashLayer::init()
{
CCDL_PERFORM_SELECTOR( this, 4.f, CCSplashLayer::runGame );
}

Answer 3

try like this...
in init method,
this->runAction(CCSequence::create(CCDelayTime::create(4.0f),
CCCallFuncN::create(this,callfuncN_selector(CCSplashLayer::runGame)),
NULL));
and add this method.
void CCSplashLayer::runGame(){
auto scene = HelloWorld::createScene();
Director::getInstance()->setDepthTest(true);
TransitionScene *transition = TransitionScene::create(0.5f, scene);
Director::getInstance()->pushScene(transition);
}
