Cocos-x-----第一节----HelloWorld

1：通过模版建立cocos2d-Win32-Application项目

2：建立后，并根据此文cocos2D-x的安装及配置设置并添加完杂乱的东西

上面的结构好熟悉，跟XCode建立的工程目录简直一样

一个委托文件，一个场景，和IOS开发中的场景差不多，在最新的IOS5.0以后，苹果所鼓励的使用的storyboard中，控制器也叫“场景”。

#ifndef __APP_DELEGATE_H__
#define __APP_DELEGATE_H__

#include "CCApplication.h"

/**
@brief	The cocos2d Application.

The reason for implement as private inheritance is to hide some interface call by CCDirector.
*/
class  AppDelegate : private cocos2d::CCApplication
{
public:
    AppDelegate();
    virtual ~AppDelegate();

    /**
    @brief	Implement for initialize OpenGL instance, set source path, etc...
    */
    virtual bool initInstance();

    /**
    @brief	Implement CCDirector and CCScene init code here.
    @return true    Initialize success, app continue.
    @return false   Initialize failed, app terminate.
    */
    virtual bool applicationDidFinishLaunching();

    /**
    @brief  The function be called when the application enter background
    @param  the pointer of the application
    */
    virtual void applicationDidEnterBackground();

    /**
    @brief  The function be called when the application enter foreground
    @param  the pointer of the application
    */
    virtual void applicationWillEnterForeground();
};

#endif  // __APP_DELEGATE_H__

下面是两个最主要的函数，是不是很熟悉，是的跟IOS上的一样

bool AppDelegate::applicationDidFinishLaunching()
{
    // initialize director
    CCDirector *pDirector = CCDirector::sharedDirector();
    pDirector->setOpenGLView(&CCEGLView::sharedOpenGLView());

	// enable High Resource Mode(2x, such as iphone4) and maintains low resource on other devices.
//     pDirector->enableRetinaDisplay(true);

    // turn on display FPS
    pDirector->setDisplayFPS(true);

    // set FPS. the default value is 1.0/60 if you don't call this
    pDirector->setAnimationInterval(1.0 / 60);

    // create a scene. it's an autorelease object
    CCScene *pScene = HelloWorld::scene();

    // run
    pDirector->runWithScene(pScene);
    return true;
}

// HelloWorldScene.cpp文件中的init，主要完成此场景中元素的初始化

// on "init" you need to initialize your instance

bool HelloWorld::init()
{
    bool bRet = false;
    do 
    {
        //////////////////////////////////////////////////////////////////////////
        // super init first
        //////////////////////////////////////////////////////////////////////////

        CC_BREAK_IF(! CCLayer::init());

        //////////////////////////////////////////////////////////////////////////
        // add your codes below...（在此处添加自己的代码）
		//添加我的第一个cocos2D-x  Label
		//游戏开发从这里起步...加油
		CCLabelTTF* pMyLabel = CCLabelTTF::labelWithString("Cocos2D-x  begining...\n Come  on !", "Thonburi", 24);
        CC_BREAK_IF(! pMyLabel);

        // 获得窗体的Size，设置Label的位置. 
        CCSize size = CCDirector::sharedDirector()->getWinSize();
        pMyLabel->setPosition(ccp(size.width/5+150, size.height/7-10));

        // 添加为子视图.
        this->addChild(pMyLabel, 1);
        //////////////////////////////////////////////////////////////////////////

        // 1. Add a menu item with "X" image, which is clicked to quit the program.

        // Create a "close" menu item with close icon, it's an auto release object.
        CCMenuItemImage *pCloseItem = CCMenuItemImage::itemFromNormalImage(
            "CloseNormal.png",
            "CloseSelected.png",
            this,
            menu_selector(HelloWorld::menuCloseCallback));
        CC_BREAK_IF(! pCloseItem);

        // Place the menu item bottom-right conner.
        pCloseItem->setPosition(ccp(CCDirector::sharedDirector()->getWinSize().width - 20, 20));

        // Create a menu with the "close" menu item, it's an auto release object.
        CCMenu* pMenu = CCMenu::menuWithItems(pCloseItem, NULL);
        pMenu->setPosition(CCPointZero);
        CC_BREAK_IF(! pMenu);

        // Add the menu to HelloWorld layer as a child layer.
        this->addChild(pMenu, 1);

        // 2. Add a label shows "Hello World".

        // Create a label and initialize with string "Hello World".
        CCLabelTTF* pLabel = CCLabelTTF::labelWithString("Hello World", "Thonburi", 64);
        CC_BREAK_IF(! pLabel);

        // Get window size and place the label upper. 
        //CCSize size = CCDirector::sharedDirector()->getWinSize();
        pLabel->setPosition(ccp(size.width / 2, size.height - 20));

        // Add the label to HelloWorld layer as a child layer.
        this->addChild(pLabel, 1);

        // 3. Add add a splash screen, show the cocos2d splash image.
        CCSprite* pSprite = CCSprite::spriteWithFile("HelloWorld.png");
        CC_BREAK_IF(! pSprite);

        // Place the sprite on the center of the screen
        pSprite->setPosition(ccp(size.width/2, size.height/2));

        // Add the sprite to HelloWorld layer as a child layer.
        this->addChild(pSprite, 0);

        bRet = true;
    } while (0);

    return bRet;
}

// OK 效果如下
