分布式游戏服务端引擎KBEngine C++实现的分布式游戏服务端引擎KBEngine详解
人气:0想了解C++实现的分布式游戏服务端引擎KBEngine详解的相关内容吗，在本文为您仔细讲解分布式游戏服务端引擎KBEngine的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：分布式,游戏服务端引擎,KBEngine，下面大家一起来学习吧。
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。)
