---------------------------------快过节了,弄个案例,大家不妨假期做做,
运行效果展示:
全部代码和资源:

1.准备资源
背景图片menuback.png:
节点图片
greenstar.png
redstar.png
yellowstar.png
2.创建一个新项目(如何配置环境和创建新项目,参考前面教程):
cocos new -p com.xdl.game -l cpp -d ~/Desktop/test0515 snamegame
首先将HelloWoldScene.h HelloWorld.cpp移走,然后添加GameScene.h GameScene.cpp HelpScene.h HelpScene.cpp MainMenu.h MainMenu.cpp
加上原来自动生成的AppDelegate.h 和AppDelegate.cpp共8个文件
4.编码
AppDelegate.h (这个文件基本没改动)
#ifndef _APP_DELEGATE_H_
#define _APP_DELEGATE_H_
#include"cocos2d.h"
class AppDelegate :privatecocos2d::Application
{
public:
AppDelegate();
virtual~AppDelegate();
virtualboolapplicationDidFinishLaunching();
virtualvoidapplicationDidEnterBackground();
virtualvoidapplicationWillEnterForeground();
};
#endif// _APP_DELEGATE_H_
AppDelegate.cpp
#include"AppDelegate.h"
#include"MainMenu.h"
#include"SimpleAudioEngine.h"
USING_NS_CC;
usingnamespaceCocosDenshion;
AppDelegate::AppDelegate() {
}
AppDelegate::~AppDelegate()
{
boolAppDelegate::applicationDidFinishLaunching() {
// initialize director
autodirector =Director::getInstance();
autoglview = director->getOpenGLView();
if(!glview) {
glview =GLView::create("My Game");
director->setOpenGLView(glview);
}
// turn on display FPS
director->setDisplayStats(false);
// set FPS. the default value is 1.0/60 if you don't call this
director->setAnimationInterval(1.0/60);
// create a scene. it's an autorelease object
autoscene =MainMenu::createScene();
// run
director->runWithScene(scene);
//开始播放背景音乐
SimpleAudioEngine::getInstance()->playBackgroundMusic("background.mp3");
returntrue;
}
// This function will be called when the app is inactive. When comes a phone call,it's be invoked too
voidAppDelegate::applicationDidEnterBackground() {
Director::getInstance()->stopAnimation();
// if you use SimpleAudioEngine,it must be pause
SimpleAudioEngine::getInstance()->pauseBackgroundMusic();
// this function will be called when the app is active again
voidAppDelegate::applicationWillEnterForeground() {
Director::getInstance()->startAnimation();
SimpleAudioEngine::getInstance()->resumeBackgroundMusic();
}
说明: 在入口类中加入了背景音乐的播放,并且入口场景设计为MainMenu,往下看MainMenu.h
