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

 1 #include "AppDelegate.h"
 2 //#include "HelloWorldScene.h"
 3 #include "MyScene.h"
 4 
 5 USING_NS_CC;
 6 
 7 AppDelegate::AppDelegate() {
 8 
 9 }
10 
11 AppDelegate::~AppDelegate() 
12 {
13 }
14 
15 bool AppDelegate::applicationDidFinishLaunching() {
16     // initialize director
17     CCDirector* pDirector = CCDirector::sharedDirector();
18     CCEGLView* pEGLView = CCEGLView::sharedOpenGLView();
19 
20     pDirector->setOpenGLView(pEGLView);
21     
22     // turn on display FPS
23     pDirector->setDisplayStats(true);
24 
25     // set FPS. the default value is 1.0/60 if you don't call this
26     pDirector->setAnimationInterval(1.0 / 60);
27 
28     // create a scene. it's an autorelease object
29     //CCScene *pScene = HelloWorld::scene();
30     CCScene *pScene = MyScene::createScene();
31 
32     // run
33     pDirector->runWithScene(pScene);
34 
35     return true;
36 }
37 
38 // This function will be called when the app is inactive. When comes a phone call,it's be invoked too
39 void AppDelegate::applicationDidEnterBackground() {
40     CCDirector::sharedDirector()->stopAnimation();
41 
42     // if you use SimpleAudioEngine, it must be pause
43     // SimpleAudioEngine::sharedEngine()->pauseBackgroundMusic();
44 }
45 
46 // this function will be called when the app is active again
47 void AppDelegate::applicationWillEnterForeground() {
48     CCDirector::sharedDirector()->startAnimation();
49 
50     // if you use SimpleAudioEngine, it must resume here
51     // SimpleAudioEngine::sharedEngine()->resumeBackgroundMusic();
52 }

MyScene.h内容

MyScene.cpp内容

 8     return scene;
 9 };

12 bool MyScene::init()
13 {
14     if( !CCLayer::init() ){
15         return false;
16     }
17     CCSize size = CCDirector::sharedDirector()->getWinSize();
18     CCSprite *sprite = CCSprite::create("pal4.png");
19     sprite->setAnchorPoint( ccp(0.5f, 0.5f) );
20     sprite->setPosition( ccp(size.width/2, size.height/2) );
21     sprite->setScale(0.5f);
22     addChild(sprite);
23 
24     return true;
25 }
