c++游戏服务器开发（C++游戏服务器开发入门到掌握）

KBEngine 是一款开源的游戏服务端引擎，使用简单的约定协议就能够使客户端与服务端进行交互，
使用KBEngine插件能够快速与(Unity3D, OGRE, Cocos2d, HTML5, 等等)技术结合形成一个完整的客户端。

服务端底层框架使用c++编写，游戏逻辑层使用Python(支持热更新)，开发者无需重复的实现一些游戏服务端通用的底层技术，
将精力真正集中到游戏开发层面上来，快速的打造各种网络游戏。

(经常被问到承载上限，kbengine底层架构被设计为多进程分布式动态负载均衡方案，
理论上只需要不断扩展硬件就能够不断增加承载上限，单台机器的承载上限取决于游戏逻辑本身的复杂度。)
