Cocos2d 之FlyBird开发---GameScore类

　　这个类主要实现的是，显示历次成绩中的最好成绩。当然我写的这个很简洁，还可以写的更加的丰富。下面贴上代码：

GameScore.h

#ifndef _GAME_SCORE_H_
#define _GAME_SCORE_H_

#include "cocos2d.h"
USING_NS_CC;

class GameScore : public cocos2d::Layer
{
private:
     cocos2d::Sprite* background;
     cocos2d::MenuItemImage* awayItem;

public:
     static cocos2d::Scene* createScene();
     virtual bool init();
     void scoreInterface();
     void goMainInterface(cocos2d::Ref*);
     CREATE_FUNC(GameScore);
};

#endif // _GAME_SCORE_H_

GameScore.cpp

#include "GameScore.h"
#include "GameUnit.h"
#include "MainMenu.h"
#include "GameData.h"

unit u2;

cocos2d::Scene* GameScore::createScene()
{
     Scene* scene = Scene::create();
     GameScore* layer = GameScore::create();
     scene->addChild(layer);
     return scene;
}

bool GameScore::init()
{
     if (!Layer::init())
     {
              return false;
     }

     this->scoreInterface();

     return true;
}

void GameScore::scoreInterface()
{
     background = Sprite::create("background/score.png");
     background->setPosition(Vec2(u2.winOrigin().x + u2.winSize().width / 2,
              u2.winOrigin().y + u2.winSize().height / 2));
     background->setScale(u2.scaleX(background, u2.winSize()),
              u2.scaleY(background, u2.winSize()));
     this->addChild(background, 0);

     awayItem = MenuItemImage::create(
              "button/away.png",
              "button/buttom.png",
              CC_CALLBACK_1(GameScore::goMainInterface, this));
     awayItem->setPosition(Vec2(u2.winOrigin().x + awayItem->getContentSize().width / 2,
              u2.winOrigin().y + awayItem->getContentSize().height / 2));
     auto m = Menu::create(awayItem, NULL);
     m->setPosition(Vec2::ZERO);
     this->addChild(m, 2);

     int bestScore = GameData::getGameData();
     cocos2d::LabelTTF* score = LabelTTF::create("0", "Arial", 26);
     score->setPosition(Vec2(u2.winSize().width / 2,
              u2.winSize().height / 2));
     this->addChild(score, 4);
     score->setColor(Color3B(0, 0, 0));
     score->setString(__String::createWithFormat("%d : Pipe", bestScore - 1)->getCString());
}

void GameScore::goMainInterface(cocos2d::Ref* pSender)
{
     Director::getInstance()->replaceScene(TransitionFadeBL::create(1,
              MainMenu::createScene()));
}
