cocos2d-x学习记录1——图片显示

这篇算是cocos2d-x入门篇，显示一张图片即可。

观察工程中HelloWorld的结构，包含AppDelegate和HelloWorldScene两个类文件，AppDelegate中包含基本的处理，并且创建最初要显示的Scene并运行之。

而HelloWorldScene中则做了相关的初始化工作，在这里，自己仿照HelloWorldScene写个更简单的Scene用于显示。

AppDelegate.cpp内容

 #include "AppDelegate.h"
 //#include "HelloWorldScene.h"
 #include "MyScene.h"

 USING_NS_CC;

 AppDelegate::AppDelegate() {

 }

 AppDelegate::~AppDelegate()
 {
 }

 bool AppDelegate::applicationDidFinishLaunching() {
     // initialize director
     CCDirector* pDirector = CCDirector::sharedDirector();
     CCEGLView* pEGLView = CCEGLView::sharedOpenGLView();

     pDirector->setOpenGLView(pEGLView);

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

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

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

     // run
     pDirector->runWithScene(pScene);

     return true;
 }

 // This function will be called when the app is inactive. When comes a phone call,it's be invoked too
 void AppDelegate::applicationDidEnterBackground() {
     CCDirector::sharedDirector()->stopAnimation();

     // if you use SimpleAudioEngine, it must be pause
     // SimpleAudioEngine::sharedEngine()->pauseBackgroundMusic();
 }

 // this function will be called when the app is active again
 void AppDelegate::applicationWillEnterForeground() {
     CCDirector::sharedDirector()->startAnimation();

     // if you use SimpleAudioEngine, it must resume here
     // SimpleAudioEngine::sharedEngine()->resumeBackgroundMusic();
 }

MyScene.h内容

 #ifndef MyScene_H_H
 #define MyScene_H_H

 #include "cocos2d.h"
 using namespace cocos2d;

 class MyScene : public CCLayer
 {
 public:
     static CCScene* createScene();
     virtual bool init();
     CREATE_FUNC( MyScene );

 private:
 };

 #endif

MyScene.cpp内容

 #include "MyScene.h"

 CCScene* MyScene::createScene()
 {
     CCScene *scene = CCScene::create();
     MyScene *layer = MyScene::create();
     scene->addChild(layer);
     return scene;
 };

 bool MyScene::init()
 {
     if( !CCLayer::init() ){
         return false;
     }
     CCSize size = CCDirector::sharedDirector()->getWinSize();
     CCSprite *sprite = CCSprite::create("pal4.png");
     sprite->setAnchorPoint( ccp(0.5f, 0.5f) );
     sprite->setPosition( ccp(size.width/, size.height/) );
     sprite->setScale(0.5f);
     addChild(sprite);

     return true;
 }

运行结果：
