本文深入探讨了网络游戏开发的基本思路和技术细节，重点介绍了客户端与服务器之间的交互机制，包括客户端如何发送命令给服务器，服务器如何处理这些命令并反馈结果。
学习手机网游的开发，说实话，网游开发这个话题太大，我也没啥经验，毕业这么多年参与的20多款游戏中，一共只做了3个网游项目，前两个是kjava的手机网游（这个实在是，当时所在单位想法是好的，但现实很残酷，j2me性能不足以满足需要），第三个是as3的webgame（因为种种原因难产），但很遗憾，没一个成功的，因为本人能力的先天不足（我大学主修的不是计算机），不过就通过对九秒开源例子打小三，谈谈网游基本的开发思路吧，打小三是9秒出的一款基于firefly服务器引擎的开源例子（最近9秒很不务正业，说实话，作为一个有自己很好产品线的技术企业，现在不把精力用在推广自己的几个开源的产品上，而是去搞其他产品的推广和培训，我觉得有些不理解），回到我们的话题上来，我们看下打小三是个什么东东，我们先把它运行起来
首先启动服务器：如下面

我们看下工程
刚刚我们打开的是GameUseTool，现在我们打开beatgirl
的确，那网络版本的实现是不是也跟单机版差不多呢，答案是差不多，不过裁决方式不同，单机版使用的裁决方式是客户端裁决，而网络版使用的服务器端裁决机制，而这个机制是怎么实现的呢？
我们看下网络版的代码

init（）我们看下createTheInterface()这个方法
这个方法中画出了我们这个屏幕中显视的所有东西，包括，背景，按钮，输入框等等，我们不赘述其他的，只关心里面的一个callback，我们看看callback里面实现了什么东西
void MZStartAnimation::callBack(CCObject* pSender){
std::string str = CCUserDefault::sharedUserDefault()->getStringForKey("NAME");
str = "111";
if (!str.empty() && str.compare("") != 0) {
MZDataManager* dataManager = MZDataManager::sharedDataManager();
/* CSCSJson::FastWriter writer;
CSCSJson::Value data;*/
CSJson::FastWriter writer;
CSJson::Value data;
data["name"] = str.c_str();
std::string CSJson_data = writer.write(data);
dataManager->sendMessage(CSJson_data.c_str(), 1000);
this->schedule(schedule_selector(MZStartAnimation::receive_1000));
_loading = Loading::create();
this->addChild(_loading, 5);
}
}我们可以看到这里面通过json把str字符串做了格式化，然后用sendMessage方法把格式化好的字符串发出，而消息号是1000
在发出消息之后用一个计划来监听receive_1000
当接收到服务器端的指令之后
void MZStartAnimation::receive_1000(float dt)
{
MZDataManager* dataManager = MZDataManager::sharedDataManager();
Message* msg = (Message *)dataManager->m_dictionary->objectForKey(1000);
dataManager->m_dictionary->removeObjectForKey(1000);
if (msg) {
_loading->removeFromParent();
this->unschedule(schedule_selector(MZStartAnimation::receive_1000));
char* receive_data = msg->data;
/* CSCSJson::Reader reader;
CSCSJson::Value root;*/
CSJson::Reader reader;
CSJson::Value root;
if (!reader.parse(receive_data, root)) {
return;
}
//CSCSJson::Value data;
CSJson::Value data;
data = root["rev_data"];
dataManager->setUserID(data["user_id"].asInt());
dataManager->setUserInfo(receive_data);
CCScene* scene = CCScene::create();
MZStartGame* layer = MZStartGame::create();
scene->addChild(layer);
CCTransitionFade* transitionScene = CCTransitionFade::create(0.1f, scene);
CCDirector::sharedDirector()->pushScene(transitionScene);
}我们看下这个时候服务器做了什么，我们点账号登录

我们看下，单机c++的通用网络模块都包含哪些东西
这是客户端，我们看下服务器端是怎么实现的，关掉vs，和服务器，看看代码，
对了，忘了说了，我在9秒群里发win32版本的时候，有些小伙伴加载了我的测试好的代码，却出了很奇怪的一个错误，这个是因为使用上面的c++通过模块需要使用win自带的api，只要在链接器里面添加ws2_32.lib就可以了
好了看服务器。我们为方便打开eclipse
我们关闭其他的，只看mzdemo
打开config.json

Firefly框架参考
在游戏服务器端，往往需要处理大量的各种各样的任务，每一项任务所需的系统资源也可能不同。而这些复杂的任务只用一个单独的服务器进程是很难支撑和管理起来的。所以，游戏服务器端的开发者往往需要花费大量的时间精力在诸如服务器类型的划分，进程数量的分配，以及这些进程的维护，进程间的通讯，请求的路由等等这些底层的问题上。而Firefly完全可以完成这些重复而繁琐的工作，从而将上层的游戏开发者解放出来，把精力更多的放在游戏逻辑的实现上面。
一、Firefly特性
1、采用单线程多进程架构，支持自定义的分布式架构。
2、方便的服务器扩展机制，可快速扩展服务器类型和数量
3、与客户端采用TCP长连接，无需考虑粘包等问题。
二、Firefly思路
一个最基本的服务器就是一个在不停运行着的应用程序。在分布式游戏服务器中，我们需要的服务器具有的功能有，监听客户端的连接，监听其他服务进程的消息，连接其他的服务进程，有些需要有数据库连接和缓存服务。如图
net connect 做客户端连接，root监听其他服务进程消息，node连接其他服务进程，db数据库，cache缓存。是否需要监听客户端连接，是否监听其他服务进程消息等这是都是可以在config.json中进行配置。包括各个服务器的名称以及各个服务器之间的连接关系。这样就可以自定义出自己的分布式架构。
三、Firefly结构
从功能职责上来看，Firefly框架结构如下图所示：
1、management, firefly 是个多进程、分布式的游戏服务器。因此各游戏server(进程)的管理和扩展是firefly很重要的部分，框架通过抽象使服务器的扩展非常容易。
2、Network，客户端连接通信、server进程间的通信等构成了整个游戏框架的脉络，所有游戏流程都构建在这个脉络上。与客户端的通信采用的是请求/回应式的，所有收到的客户端的请求，服务端都会给出相应的回应，服务端也能主动的推送，广播给客户端消息。这些请求是基于指令号的请求。（例如定义101为登陆指令）server进程之间的通信时采用的异步回调的方式，这样就减少了的进程间通过网络通信中的时间消耗。
3、Data, 数据处理是网游的重要部分。在网游有大量的数据需要存储，需要更新，这使得数据库的读写效率成为服务器的最大的性能瓶颈。firefly的db处理能够将数据库表中的数据缓存到memcache中并能以对象的形式进行调用相应的对象方法对数据进行操作。可以在不同的进程中通过实例化相同的名称的缓存实例，得到同步的数据。并能将缓存对象中的数据写回数据库中。
1.从config.json中读取配置数据
2.根据配置中定义的服务端的架构，启动相应的服务进程。并建立节点之间的连接。有配置数据库的，实例化数据库连接池。有配置memcached的，建立memcached的连接。
3.根据配置相应的的进程启动的入口模块。

看到了吧，我们服务器处理客户端的几个消息的方法都在这了，其实网络游戏我们就可以把它看成一个我们本应该在本地做的工作，通过命令发到服务器去做，这个跟我们现在说的云有点相似，上面这些方法处理上面都有一个@gate_localservice_handle修饰，我们可以把它看成是一个方法的参数，最后这个参数被gate_localservice_handle调用，就是target这个东西，由 gateLocalService.mapTarget(target)来处理。
好了，这篇就到这，下篇我们看下我们一直以来做的仙剑demo剧情效果和制作方法，最后放出源码
