定义
MMORPG任务编辑器用于配置人物与地图NPC、怪物、玩家、场景等相关的任务交互操作，处理诸如与NPC对话、杀死BOSS、收集物品等事件，并设置这些事件的响应过程及触发/完成条件等等。例如：接受设置玩家可以通过与地图上某NPC对话接受一个任务，杀死10个指定的怪物，那么任务编辑器就需要对任务的接受条件、完成条件、任务相关变量、自动寻路、杀死怪物后的提示信息等功能进行配置。
设计理念
首先，任务编辑器是提供给策划人员使用的，而策划人员一般都不懂得编程，所以其设计应遵循WYSIWYG（What You See Is What You Get ，所见即所得）的原则，做到傻瓜化；其次，编辑器应该具有按地图过滤任务、搜索指定任务、任务描述彩色显示、任务变量超链接样式显示（点击超链接时弹出编辑对话框）、插入自动寻路超链接（可以弹出的对话框中手动填写或按地图选择指定NPC）等功能；再次，任务编辑器的布局应该按照功能来分配，尽量做到符合用户的思维习惯，做到“最小惊奇”原则；最后，任务编辑器应该预留足够的扩展性，以满足游戏玩法的扩展。
带来的优势
通过WYSIWYG的设计理念，可以最大程度的减少策划的心智负担，从而减少其出错的可能性，减少与程序员沟通、调试的成本，显著的提升了团队写作效率；通过提供任务搜索的功能，可以加速策划定位到相应的任务，完成修改、删除等操作，提升策划工作效率；编辑器可以实现源码级别上的复用，公司新开发一个MMORPG，那么只需要在原有的任务编辑器基础上增加、删除功能即可，降低总体拥有成本。
任务响应机制设计
MMORPG具有强交互的特性，玩家的每一个操作都可以看作是一种特定类型的事件，因此基于消息的事件响应模型非常适合完成此任务。例如：玩家进入场景，可以抽象为on_enter事件，并且客户端向服务器发送on_enter事件，服务器端将其压入消息队列，并进行处理，而后返回处理结果。
任务脚本结构设计
任务编辑器是对任务脚本的抽象，将其细节隐藏，而脚本最终还是需要由程序处理，因此必须仔细进行设计。这里给出的是国内某著名网络游戏的脚本设计，其任务脚本都包含在quest文件夹中，所有通过玩家任务列表查看的任务都保存在quests.xml中，而相应的事件，则保存在on_drop、on_enter、on_get这些事件文件夹中，事件文件夹中的文件是以NPC_ID进行命名，以此来配置不同NPC对不同事件的响应操作，如下图所示：
首先，我们来看quests.xml文件中的数据结构：
关键技术点--RichTextBox字体着色
字体着色非常简单，这里用到了一个RichTextBoxLinks的第三方控件，对于<description>标签中的XML文档，可以直接使用以下代码进行染色：
对于上图的情况，使用贪心算法将“分组1”和“分组3”的字体颜色进行提取，并构造XML数据，这里“分组1”和“分组3”字体颜色一样，贪心算法计算的结果是将整个分组封装成一个标签。
之所以说这个算法复杂是因为实际的情况远比上面的例子要复杂，需要处理各种边界问题，下面将关键代码贴出，其复杂性大家一看便知：

} } #endregion }}总结 衡量任务编辑器的好坏没有一个固定的标准，只要符合项目的实际需要即可，不过可以肯定的是，“所见即所得”的功能越强大、操作越简单，那么这个编辑器的价值就越大。欢迎大家探讨游戏编辑器的相关话题，包括但不局限于任务编辑器:-)
