MMORGP大型游戏设计与开发(客户端架构 part16 of vegine)

由于近来比较忙碌和有些困倦的原因,所以关于这部分的文章没有及时更新,一句话:让朋友们久等了!今天所讲的是客户端vengine(微引擎)中最后一个部分,就像上节所说,这一部分的内容比较多。可能有些朋友看了代码以及注释后,仍有不少疑惑的地方,欢迎评论留言相互讨论,如果有不好的地方,也希望大家勇于批评与指正。游戏模块,是提供给客户端最核心的部分,它将直接影响到游戏内容,如数据、渲染等。

解释

  在这里游戏中的一些常用模块,如对象、场景、UI、数据,这些我就不在这里解释过多了,因为它们都依赖于引擎提供的接口,以后会有机会再详细同大家一起探讨和研究。

  游戏中的事件系统,在这里我要特别说说,因为在天龙/武侠在这个模块上设计是比较聪明的。那么什么是事件呢,什么情况下会产生事件?事件其实就是游戏中某次操作或系统定点执行的某种动作,所谓事件就是一件事情。事件系统就是在事件产生的时候,管理该事件所需执行的动作而出现的。如界面的数据改变了,我们就需要更新界面,其中界面的数据改变了就是一个事件,而更新界面就是事件下产生的动作。

  程序中常常有回调的说法,其实事件管理系统就是一种回调分发器,与回调不同的是事件管理器是集中管理,定时执行的。在这里,事件管理系统将事件的动作分为慢和快,快的在一次循环帧内一次执行完成,而慢的就有所谓的时间间隔,这样设计的好处就是使时间有了先后之分。

总结

  vengine(微引擎)的讲解结束了,游戏中的所有接口大家有些印象了吗?如果没有,则你可以从头再读一次这些文章,希望对大家有所帮助。接下来会开始讲解vgui(微GUI),结合CEGUI的界面管理的封装。
