从零开始搭建TestCpp工程

目标： 创建一个测试工程，测试工程以列表的方式展示，没一个列表项对应一个场景

1. 创建cocos2d-x工程

      现在采用脚本的方式来创建，好处是一次可以创建N个项目的工程。

     首先要安装Python , 官网既可 下载，我下载的是 V2.7.5 X64，下载完成后安装到本地。

     配置环境变量：

    打开 计算机-> 属性-> 高级系统设置 -> 环境变量 ，在系统变量里找到 Path 这一项，在后面添加 一句：

    D:\DevTools\Python;

   其中后面那个是你安装的Python的目录，然后打开 命令行，按照下图，

   首先定位到 cocos2d-x目录下的 tools\project-creator,  然后输入 对应的脚本

  

   python create_project.py -project MyGame -package com.MyCompany.AwesomeGame -language cpp

    MyGame 是你的游戏的名称  com.MyCompany.Awesome 是安卓,ios里用到的包名，按需修改，其它的照填就可以了。

    完成之后打开 cocos2d-x 目录下的 project 文件夹，看到如下所示，进入 project.win32 就是我们的开发环境了，

     打开 *.sln ，熟悉的界面来了，小伙伴们赶紧动手把。

     最近刚才发现一个问题，因为这个项目都是拷贝的模板来的，所以应用的唯一标识都是一个。这对于发布应用没有什么影响，因为微软会对应用进行重新签名打包。

      但是在调试的时候，后一个应用会自动覆盖前一个应用，如果要破，请自行创建一个新应用，然后替换唯一标识！

    

2. 实现原理：

     AppDelegate.cpp ---> 添加列子控制层TestController.cpp ----> 没添加一个场景测试项目，则添加一个对应的菜单  ---> 点击菜单启动场景TestScene。

     每一个场景测试项目都继承TestScene，然后实现方法：runThisTest

3. AppDelegate.cpp 说明

#include "AppDelegate.h"
#include "controller.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 / 60);

    CCScene * pScene = CCScene::create();

    CCLayer * pLayer = new TestController();
    pLayer->autorelease();  //这里为什么play要放到自动释放，而pScene 不需要，因为pScene用的静态工厂方法创建的

    pScene->addChild(pLayer);
    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();
}
