Cocos2d-x 捕鱼达人游戏学习教程（8）--添加PanelLayer数据面板层

代码下载 http://vdisk.weibo.com/s/BDn59yfnBV9dj

我们要在GameScene.h中添加如下代码：

 //数据面板层
    CC_SYNTHESIZE_RETAIN(PanelLayer*, _panelLayer, PaneLayer);

    //菜单页面相关的函数
    //暂定
    void pause();

之后我们要完成PanelLayer.h

#include "cocos2d.h"
USING_NS_CC;

class PanelLayer:public CCLayer
{

public:
    CREATE_FUNC(PanelLayer);
    bool init();
    void pause();
};

PanelLayer.cpp

#include "GameScene.h"
#include "StaticData.h"

bool PanelLayer::init()
{
    bool pRet = false;
    do {
        CC_BREAK_IF(!CCLayer::init());
        CCSize winSize = CCDirector::sharedDirector()->getWinSize();

        CCMenuItemSprite* pause = CCMenuItemSprite::create(CCSprite::createWithSpriteFrameName(STATIC_DATA_STRING("pause_normal")), CCSprite::createWithSpriteFrameName(STATIC_DATA_STRING("pause_selected")), this, menu_selector(PanelLayer::pause));

        CCMenu* menu = CCMenu::create(pause,NULL);
        this->addChild(menu);

        CCSize pauseSize = pause->getContentSize();
        menu->setPosition(ccp(winSize.width - pauseSize.width * 0.5, pauseSize.height * 0.5));

        pRet = true;
    } while (0);
    return pRet;
}

void PanelLayer::pause()
{
    //getParent()方法找到当前层的父类，当前层是加在GameScene中的因此
    GameScene* gameScene = (GameScene*)this->getParent();
    gameScene->pause();

}

GameScene.cpp的  bool GameScene ::init()方法中添加如下代码

 //创建显示数据层并加到场景中
        _panelLayer = PanelLayer::create();
        this->addChild(_panelLayer);

实现一个空的pause函数

void GameScene::pause()
{

}
