Hi there. It is me again.

After I watched the episode “Saving The Score”of Creating Flappy Bird Cocos2d-x Course, I tried to implement this pretty cool function in my code.

Unforetunately, I failed and did not know why, so I tried to copy and paste the partial lesson source code which was modified in the lesson.

Surprisingly, it still did not work. My highscore never got updated. It just followed what I have scored in current game.

Would you mind checking my code and see what is going on? Thanks.

Here is my code below.

#include "GameOverScene.h"
#include "GameScene.h"
#include "MainMenuScene.h" 
#include "Definitions.h"

USING_NS_CC;

unsigned int score;

Scene* GameOverScene::createScene(unsigned int tempscore)
{	
	score = tempscore;
    // 'scene' is an autorelease object
    auto scene = Scene::create();
    
    // 'layer' is an autorelease object
    auto layer = GameOverScene::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 GameOverScene::init()
{
    //////////////////////////////
    // 1. super init first
    if ( !Layer::init() )
    {
        return false;
    }
    
    Size visibleSize = Director::getInstance()->getVisibleSize();
    Vec2 origin = Director::getInstance()->getVisibleOrigin();

	auto backgroundSprite = Sprite::create("background.jpg");
	backgroundSprite->setPosition(Point(visibleSize.width / 2 + origin.x, visibleSize.height / 2 + origin.y));

	this->addChild(backgroundSprite);

	auto retryItem = MenuItemImage::create("RetryButton.png", "RetryButtonClicked.png", CC_CALLBACK_1( GameOverScene::GoToGameScene,this));
	retryItem->setPosition(Point((visibleSize.width + origin.x) / 3 * 1, visibleSize.height / 2 + origin.y));
	auto mainMenuItem = MenuItemImage::create("MenuButton.png", "MenuButtonClicked.png", CC_CALLBACK_1(GameOverScene::GoToMainMenuScene, this));
	mainMenuItem->setPosition(Point((visibleSize.width + origin.x) / 3 * 2, visibleSize.height / 2 + origin.y));

	auto menu = Menu::create(retryItem, mainMenuItem, NULL);
	menu->setPosition(Point::ZERO);
	this->addChild(menu);	

	UserDefault *def = UserDefault::getInstance();
	auto highScore = def->getIntegerForKey("HIGHSCORE FLAPPY", 0);
	if (score>highScore)
	{
		highScore = score;
		def->setIntegerForKey("HIGHSCORE FLAPPY", highScore);
	}
	def->flush();
	
	__String *tempScore = __String::createWithFormat("Your Score: %i", score);
	auto currentScore = Label::createWithTTF (tempScore->getCString(), "fonts/Marker Felt.ttf", visibleSize.height * SCORE_FONT_SIZE);
	currentScore->setPosition(Point(visibleSize.width / 2 + origin.x, visibleSize.height * 0.7 + origin.y));
	this->addChild(currentScore);

	__String *tempHighScore = __String::createWithFormat("HighScore: %i", highScore);

	auto highScoreLabel = Label::createWithTTF(tempHighScore->getCString(), "fonts/Marker Felt.ttf", visibleSize.height * SCORE_FONT_SIZE);
	highScoreLabel->setPosition(Point((visibleSize.width + origin.x) / 2 , visibleSize.height + origin.y - highScoreLabel->getContentSize().height));
	highScoreLabel->setColor(Color3B::RED);
	highScoreLabel->enableShadow();
	this->addChild(highScoreLabel);

    return true;
}

void GameOverScene::GoToMainMenuScene(cocos2d::Ref *sender)
{
	auto scene = MainMenuScene::createScene();
	Director::getInstance()->replaceScene(TransitionFade::create(TRANSITION_TIME, scene));
}

void GameOverScene::GoToGameScene(cocos2d::Ref *sender)
{
	auto scene = GameScene::createScene();
	Director::getInstance()->replaceScene(TransitionFade::create(TRANSITION_TIME, scene));
}

ps. this is my original code, so the position of labels and buttons will be a little bit different from the source code. Thanks.
