大概三个月前，我在试着用几款2D游戏引擎。
&&& 第一款是SDL，这是同事推荐给我的一款跨平台的2D游戏引擎。这款引擎评价很高，总的来说是因为它够底层，实现的功能非常基本，又提供了一套平台无关的接口。所以开发人员在此之上可以天马行空的开发。不过我不是那么热衷底层&&于是我在写了几个实验性的程序之后放弃了他。呵呵，当时研究它主要是因为自己也在做嵌入式，对跨平台很感兴趣。但是当时看一个老外，好像叫lazyfoo，写的开发教程让我学到了很多游戏开发方面基本的知识。
&&& 然后第二款是HGE，它是基于driectX的一款开源2D游戏引擎，也是提供较底层的功能。最核心的大概是它提供基于帧的逻辑和渲染回调，开发人员来实现每帧进行的操作。HGE还提供了一套我觉得非常不好的教程，对于新手是绝对的误导&&它的教程里的代码都乱七八糟，感觉就像个C++新手写的代码一样，各种全局变量，各种魔数，各种乱命名，可读性和框架性都较差。（可能也是HGE的开发者为了求简，不过我觉得这个教程可以做的更好。）
&&& 这时，我自己做的一套简单的游戏，已经简单的设计好UI接口。于是我用HGE来实现这套接口。
&&& 我觉得HGE很恶心的地方就是它基于每帧的回调（当然你可以修改HGE内核来去除这一点，不过将带来更多麻烦，因为HGE很多函数就是基于帧回调机制的。）所以你不能像使用一个Canvas一样来进行实时绘制。于是我在游戏里自己实现了一套消息机制，把整个HGE框架跑在另一个线程中，游戏数据核心线程通过发消息的方式去通知界面更新，或者获取玩家操作。
这是当时自己弄的设计，DirectX or Ddraw改成HGE，后来自己也实现了。
刚开始的时候感觉还好，后来代码稍微上规模的话，就觉得很吃力了。因为我是基于具体游戏功能来封装HGE的接口。在之后又重构了几次，整体架构还算清晰，但是界面和代码之间的耦合度实在太大。最后可以实现一定的界面功能，但是还是太不爽了，所以决定放弃使用HGE。在此总结一下自己的想法，如果要用HGE真正开发一款稍微上规模的游戏，应该怎么做，可能也有很多不正确的地方，欢迎指正。
1. 实现页面栈、控件树
我也不知道该怎么定义这个名称，姑且叫它页面栈和控件树吧，其实就类似于WINDOWS的窗口系统，建立起树状结构的控件系统。对于每一个页面记录各种状态如焦点控件等。并通过栈维护各页面的层次关系。可以从配置文件或者页面脚本载入页面。比如游戏中的主角属性页面、装备页面等，框架都是一定的，使用的一些图片资源什么的也是一定的，应该写成配置文件，直接从文件读入。
2. 在页面树的基础上实现消息路由
消息的路由机制必须实现。
3. 建立资源管理器及配置管理器
专门的资源管理器用来加载和卸载各种图片、特效、音乐资源。同理配置管理器，管理整个HGE的配置。
4. 定义界面文件格式并使用界面文件生成具体画面，同时配套开发界面编辑器
如使用XML来定义具体界面，界面编辑器生成XML。
在1，2，3，4条满足的情况下，再进行具体游戏功能性的接口开发。甚至应该把1，2，3，4这部分抽成 引擎无关、平台无关的中间层，向下提供移植接口，用HGE来port。&& 那么整个游戏界面部分以上应该是高度可移植的。
HGE 的 gui 工具是个好东西，特别是里面的 hgeGUIObject，要多用。说个要注意的点，官网上面貌似都没给详细说明&&
hgeGUIObject 的 rect 成员是该控件的操作响应作用域&&不是显示的。让一个控件disable只要rect.Set(0,0,0,0)就行了。注意有时控件莫名其妙的不响应鼠标操作了，也可能是这个冲突导致的。这问题曾经让我崩溃的调了半天。。。
总结一下。
HGE完全开源、基于directX，功能较为基础。我觉得很适合个人学习和开发小型游戏，但是如果要做稍微大型的游戏的话，必须将整个UI的调度机制设计、封装好（我觉得这个工作量挺大），然后整以相关的开发工具。
OK,HGE就告一段落。
