Run scheduleUpdate while the resources are being loading

cocos2d-x C++
#1

Hi,

I have a “LoadingScene” where I preload resources (images, sounds…). I want to put a LoadingBar animation but it only runs where all resources have been loaded. I want to make it runs WHILE the resources are being loading.

This is the code:

#include "LoadingScene.h"
#include "MainMenuScene.h"
#include "AppManager.h"

USING_NS_CC;

Scene* LoadingScene::createScene()
{
    auto scene = Scene::create();
    auto layer = LoadingScene::create();
    scene->addChild(layer);
    return scene;
}


bool LoadingScene::init()
{
    
    if ( !LayerColor::initWithColor(Color4B(255, 255, 255, 255)) )
    {
        return false;
    }
    
    Size visibleSize = Director::getInstance()->getVisibleSize();
    Vec2 origin = Director::getInstance()->getVisibleOrigin();
    
    CocosDenshion::SimpleAudioEngine::getInstance()->playBackgroundMusic(BACKGROUNDMUSIC, true);
    
    manager = AppManager::sharedManager();
    _count = 0;
    
    loadingBar = cocos2d::ui::LoadingBar::create("sliderProgress.png", _count);
    loadingBar->setPosition(Vec2(visibleSize.width/2 + origin.x, visibleSize.height/2 + origin.y));
    loadingBar->setDirection(LoadingBar::Direction::LEFT);
    this->addChild(loadingBar, 1);

    this->scheduleUpdate();
    
    Sequence *sequence = Sequence::create(CallFunc::create(CC_CALLBACK_0(LoadingScene::preload, this)), CallFunc::create(CC_CALLBACK_0(LoadingScene::loadScene, this)), NULL);
    
    this->runAction(sequence);
    
    return true;
}

void LoadingScene::preload(){
    manager->copyDatabase();
    manager->preloadSlider();
    manager->preloadSprites();
    manager->preloadSounds();
}

void LoadingScene::update(float dt)
{
    _count++;
    if (_count > 100)
    {
        _count = 0;
    }
    loadingBar->setPercent(_count);
}

void LoadingScene::loadScene(){
    auto homeScene = MainMenu::createScene();
    Director::getInstance()->replaceScene(CCTransitionFade::create(0.7, homeScene, Color3B::WHITE));
}

Thank you!

Finally, I have used something like this: How to multi-thread?
