//1、
//cocos 程序开始运行时执行的函数
bool AppDelegate::applicationDidFinishLaunching()
{
    // initialize director
    auto director = Director::getInstance();
    director->setProjection(Director::Projection::_2D);
    
    // turn on display FPS
    director->setDisplayStats(true);
    
    // set FPS. the default value is 1.0/60 if you don‘t call this
    director->setAnimationInterval(1.0 / 60);
    director->startAnimation();

    // register lua engine
    auto engine = LuaEngine::getInstance();
    ScriptEngineManager::getInstance()->setScriptEngine(engine);
    lua_State* L = engine->getLuaStack()->getLuaState();
    lua_module_register(L);

    // If you want to use Quick-Cocos2dx-Community, please uncomment below code
    quick_module_register(L);

    LuaStack* stack = engine->getLuaStack();
//    stack->setXXTEAKeyAndSign("2dxLua", "XXTEA");
    
   //主要来看下这部分:
    StartupCall *call = StartupCall::create(this);
    call->startup();
    
    return true;
}

//2、
void StartupCall::startup()
{
    auto engine = LuaEngine::getInstance();
    auto stack = engine->getLuaStack();
    
    const ProjectConfig &project = _app->_project;
    
    // set search path
    // 设置工程搜索路径
    string path = FileUtils::getInstance()->fullPathForFilename(project.getScriptFileRealPath().c_str());
    size_t pos;
    while ((pos = path.find_first_of("\\")) != std::string::npos)
    {
        path.replace(pos, 1, "/");
    }
    size_t p = path.find_last_of("/");
    string workdir;
    if (p != path.npos)
    {
        workdir = path.substr(0, p);
        // Lua 代码文件的搜索需要包含src
        stack->addSearchPath(workdir.c_str());
        // cc.FileUtils的文件搜索去掉src目录
        size_t p = workdir.find_last_of("/");
        workdir = path.substr(0, p);
        FileUtils::getInstance()->addSearchPath(workdir);
    }
    
    // load framework
    if (project.isLoadPrecompiledFramework())
    {
        const string precompiledFrameworkPath = project.getPrecompiledFrameworkPath();
        stack->loadChunksFromZIP(precompiledFrameworkPath.c_str());
    }
    
    // load script
    string env = "__LUA_STARTUP_FILE__=\"";
    env.append(path);
    env.append("\"");
    engine->executeString(env.c_str());
    
    CCLOG("------------------------------------------------");
    CCLOG("LOAD LUA FILE: %s", path.c_str());
    CCLOG("------------------------------------------------");
    engine->executeScriptFile(path.c_str());
    
    // track start event
    trackLaunchEvent();
}

//跟踪启动事件
void StartupCall::trackEvent(const char *eventName)
{
#if (CC_TARGET_PLATFORM == CC_PLATFORM_WIN32)
    const char *platform = "win";
#elif (CC_TARGET_PLATFORM == CC_PLATFORM_MAC)
    const char *platform = "mac";
#else
    const char *platform = "UNKNOWN";
#endif
    
    HTTPRequest *request = HTTPRequest::createWithUrl(NULL,
                                                      "http://www.google-analytics.com/collect",
                                                      kCCHTTPRequestMethodPOST);
    request->addPOSTValue("v", "1");
    request->addPOSTValue("tid", "UA-84326395-1");
    request->addPOSTValue("cid", Native::getOpenUDID().c_str());
    request->addPOSTValue("t", "event");
    
    request->addPOSTValue("an", "player");
    request->addPOSTValue("av", cocos2dVersion());
    
    request->addPOSTValue("ec", platform);
    request->addPOSTValue("ea", eventName);
    
    request->start();
}
