浅谈MMORPG任务编辑器的设计与实现
By 马冬亮(凝霜 Loki)
一个人的战争(http://blog.csdn.net/MDL13412)
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:
<?xml version="1.0" encoding="gb2312"?> <quests> <quest id="1" name="编程语言选择" map="NsLib"> <description> <body> <p> <n color="255,239,196,0">任务:编程语言选择</n> </p> <p> <n> 如果想加入NsLib,可以找</n> <a href="goto 134,12">凝霜(134,12)</a> <n>咨询编程语言的相关信息。</n> </p> <p> <n color="255,239,196,0">任务描述:</n> </p> <p> <n> 听说凝霜成立了NsLib,还没有确定自己的第一门编程语言?快去去看看吧。</n> </p> <p> <n color="255,0,196,0">任务奖励:</n> </p> <p> <n color="255,239,196,0">经验奖励:</n> <n> 5</n> </p> <diffcult level="1" /> </body> </description> <events> <event type="on_visit" source="1.xml" /> <event type="on_visit" source="2.xml" /> <event type="on_enter" source="13412.xml" /> </events> </quest> <quest id="2" name="码农成长史"> <description> <body> <p> <n color="255,239,196,0">任务:码农成长史</n> </p> <p> <n> 去写10种语言的Hello World,然后向</n> <a href="goto 134,12">凝霜(134,12)</a> <n>汇报。</n> </p> <p> <n color="255,239,196,0"> Hello World:</n> <n var="kill_hello_world" task="2"/> <n>/10</n> </p> <p> <n color="255,239,196,0">任务描述:</n> </p> <p> <n> 你的第一个程序是用10种语言写Hello World。</n> </p> <p> <n color="255,0,0,240">任务奖励:</n> </p> <p> <object id="4020"> Python电子书</object> </p> <p> <object id="4050"> Lua电子书</object> </p> <diffcult level="2"/> <message color="255,255,255,20"> <n>Hello World:</n> <n var="kill_hello_world" task="2"/> <n>/10</n> </message> </body> </description> <events> <event type="on_visit" source="56001.xml"/> <event type="on_kill" source="13412.xml"/> </events> </quest> </quests>
需要特别说明的是,<quest>标签中的id必须唯一,用于表示具体任务,name可以重复,对应任务名称,而map则描述在哪个地图接受此任务。
<description>标签中的内容对应用户在任务列表中显示的描述,<a>是自动寻路的超链接,<n var=xxx>是任务变量,用于记录任务状态,<p><n>标签是文本描述,<p>在这里被转意为换行符。
<difficult level=XXX>标签表示接受此任务的等级要求;<message>是完成指定事件时,通知用户的消息;<events>对应的是事件处理脚本。
下面我们再来查看一下事件相应脚本:
<?xml version="1.0" encoding="GB2312"?> <event id="100" name="任务10"> <quest id="100" new="1"> <embranchment id="1"> <conditions> <var type="Equal" name="state" value="1"/> <var type="Less" name="kill_XXXX" value="800"/> </conditions> <actions> <var type="Add" name="kill_XXXX" value="1"/> <refresh name="kill_XXXX"/> </actions> </embranchment> <embranchment id="2"> <conditions> <var type="Equal" name="state" value="1"/> <var type="Great" name="kill_XXXX" value="799"/> </conditions> <actions> <var type="Set" name="state" value="-3"/> <refresh name="state"/> <refresh name="kill_XXXX"/> <notify content="恭喜你,你已经杀了800个40级的XXXX,去找NsLib的凝霜(134,12)领取奖赏吧!"/> <notify1 content="去找NsLib的凝霜(134,12)吧!"/> </actions> </embranchment> </quest> </event>此脚本描述任务的分支及触发/完成条件,供服务器端的事件处理器使用。
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:
/// <summary> /// 供MainForm中的任务描述RichTextBoxEx使用 /// 将任务描述字体染色并设置变量超链接 /// </summary> /// <param name="missionId">要处理的任务Id</param> /// <param name="editor">MainForm中的任务描述编辑框</param> public static void ShowRtfDescription(String missionId, RichTextBoxEx editor) { QuestXmlHandler.QuestInfo qi = (QuestXmlHandler.QuestInfo)QuestXmlHandler.QuestInfos[missionId]; StringBuilder description = new StringBuilder(); // 以行为解析单元 String line = ""; editor.SelectAll(); editor.Text = ""; try { int curPos = qi.UserDescription.Description.IndexOf("\n"); int lastPos = 0; while (-1 != curPos) { line = qi.UserDescription.Description.Substring(lastPos, curPos - lastPos); ShowRtfDescriptionImpl(line, editor); lastPos = curPos + 1; curPos = qi.UserDescription.Description.IndexOf("\n", lastPos); editor.SelectedText = "\n"; } } catch (System.Exception ex) { Logger.LogFunctionError("RichEditBoxExRtfBinder.ShowRtfDescription()", ex.Message); } }其中,QuestXmlHandler.QuestInfo qi = (QuestXmlHandler.QuestInfo)QuestXmlHandler.QuestInfos[missionId];是对任务的抽象,其关键定义如下:
/// <summary> /// 任务文件在程序中的抽象 /// </summary> public sealed class QuestXmlHandler { #region // 内嵌类 public sealed class QuestInfo { /// <summary> /// 新添加任务时自动生成的任务描述模版 /// </summary> public static String QuestDescriptionTemplate = @"<n color=""255,239,196,0"">任务:【TODO:任务名称】</n> <n> 【TODO:简短描述】</n> <n color=""255,239,196,0"">任务描述:</n> <n> 【TODO:任务描述内容】</n> <n color=""255,239,196,0"">经验奖励:</n><n>【TODO:经验】</n> "; /// <summary> /// 任务事件表,一种事件可能对应多个文件 /// </summary> public sealed class EventList { public List<String> Events_ = new List<String>(); public List<String> Events { get { return Events_; } } } public sealed class QuestDescriptionCollection { // 任务描述 private String Description_ = ""; public String Description { get { return Description_; } set { Description_ = value; } } // 任务消息 private List<String> Messages_ = new List<String>(); public List<String> Messages { get { return Messages_; } } public Boolean HasMessages() { return 0 != Messages.Count; } // 附加,任务等级要求 private int DiffcultLevel_ = -1; public int DiffcultLevel { get { return DiffcultLevel_; } set { DiffcultLevel_ = value; } } } // 任务Id,不可重复 int Id_ = -1; public int Id { get { return Id_; } set { Id_ = value; } } // 任务名称,可以重复 String Name_; public String Name { get { return Name_; } set { Name_ = value; } } // 任务所属地图 String Map_ = ""; public String Map { get { return Map_; } set { Map_ = value; } } // 事件表,每个键对应的值是一个QuestInfo结构,对应此键的所有事件相应文件。 private Hashtable EventsTable_ = new Hashtable(); public Hashtable EventsTable { get { return EventsTable_; } } // 标记此任务是否具有某项事件 private Hashtable HasEvents_ = new Hashtable(); public Boolean HasEvent(String eventName) { try { return (Boolean)HasEvents_[eventName]; } catch (System.Exception) { Logger.Error("QuestXmlReader.QuestInfo.HasEvent()键错误:key=" + eventName + " Id=" + Id.ToString() + " Name=" + Name); return false; } } public void SetEvent(String eventName) { try { HasEvents_[eventName] = true; } catch (System.Exception) { Logger.Error("QuestXmlReader.QuestInfo.SetEvent()键错误:key=" + eventName + " Id=" + Id.ToString() + " Name=" + Name); } } public void ClearEvent(String eventName) { try { HasEvents_[eventName] = false; } catch (System.Exception) { Logger.Error("QuestXmlReader.QuestInfo.ClearEvent()键错误:key=" + eventName + " Id=" + Id.ToString() + " Name=" + Name); } } public void UpdateEvents() { foreach (AppConfig.EventInfo eventInfo in AppConfig.EventInfos) { if (0 != ((EventList)EventsTable[eventInfo.EventType]).Events.Count) HasEvent(eventInfo.EventType); else ClearEvent(eventInfo.EventType); } } private QuestDescriptionCollection QuestDescription_ = new QuestDescriptionCollection(); public QuestDescriptionCollection UserDescription { get { return QuestDescription_; } } public QuestInfo() { foreach (AppConfig.EventInfo ei in AppConfig.EventInfos) { EventsTable.Add(ei.EventType, new EventList()); HasEvents_.Add(ei.EventType, false); } } } #endregion /// ... } }
对于选中的某个字符或者段落进行染色,只需使用下面代码:
private void BtnFontColor_Click(object sender, EventArgs e) { ColorDialog dlg = new ColorDialog(); dlg.AllowFullOpen = false; // 不允许使用自定义颜色 dlg.SolidColorOnly = true; // 只允许使用纯色 if (DialogResult.OK == dlg.ShowDialog()) UserMissionListDescription.SelectionColor = dlg.Color; CurrentMissionEditState.UserMissionListDescriptionChanged = true; }其中,UserMissionListDescription为RichTextBoxLinks控件的标识符,CurrentMissionEditState是标识当前任务被更改的部分。
这里的关键点是我们先前提到的RichTextBoxLinks第三方控件,我们用到了其中的InsertLink(前端显示的字符串,后台超链接);方法,下面是新插入自动寻路超链接的关键代码:
/// <summary> /// 插入自动寻路超链接 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void BtnInsertGotoHref_Click(object sender, EventArgs e) { GotoHrefForm dlg = new GotoHrefForm(GotoHrefForm.DialogType.InsertNew); dlg.ShowDialog(); if (GotoHrefForm.InsertSucceed) { CurrentMissionEditState.UserMissionListDescriptionChanged = true; // 字符串格式 NPC名字(x,y)#<a href="goto x,y">NPC名字(x,y)</a> StringBuilder href = new StringBuilder(); href.AppendFormat("<a href=\"goto {0},{1}\">{2}({3},{4})</a>", GotoHrefForm.x, GotoHrefForm.y, GotoHrefForm.NpcName, GotoHrefForm.x, GotoHrefForm.y); StringBuilder NpcNameHref = new StringBuilder(); NpcNameHref.AppendFormat("{0}({1},{2})", GotoHrefForm.NpcName, GotoHrefForm.x, GotoHrefForm.y); UserMissionListDescription.InsertLink(NpcNameHref.ToString(), href.ToString()); } }这里用到了一个HACK,即使用格式 NPC名字(x,y)#<a href="goto x,y">NPC名字(x,y)</a> 这个固定形式的字符串来标识文本框中显示的超链接内容,其符合RTF标准,此HACK为超链接编辑功能的前置条件。
任务变量的插入和自动寻路超链接类似,不过不会显示任务变量的具体名称,而统一显示为“任务变量”超链接的形式,代码如下:
/// <summary> /// 插入任务变量超链接 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void BtnInsertVar_Click(object sender, EventArgs e) { MissionVarForm dlg = new MissionVarForm(CurrentEditMission, MissionVarForm.DialogType.InsertNew); dlg.ShowDialog(); if (MissionVarForm.InsertSucceed) { CurrentMissionEditState.UserMissionListDescriptionChanged = true; // <n var="变量名" task="任务"></n> StringBuilder href = new StringBuilder(); href.AppendFormat("<n var=\"{0}\" task=\"{1}\"></n>", MissionVarForm.MissionVar, MissionVarForm.Task); UserMissionListDescription.InsertLink("任务变量", href.ToString()); } }为了支持点击超链接弹出修改对话框的功能,我们需要相应RichTextBox控件的LinkClicked事件,代码如下:
/// <summary> /// 编辑自动寻路和任务变量 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void UserMissionListDescription_LinkClicked(object sender, LinkClickedEventArgs e) { try { CurrentMissionEditState.UserMissionListDescriptionChanged = true; // text字符串的格式为 NPC名字(x,y)#<a href="goto x,y">NPC名字(x,y)</a> // 或者 任务变量#<n var="变量名" task="任务"><n> String text = e.LinkText; // 通过查找"#<"来定位我们硬编码的超链接数据 int pos = text.LastIndexOf("#<"); if (-1 == pos) return; if ('a' == text[pos + "#<".Length]) // 编辑自动寻路功能 MainFormImpl.EditNpcAutomaticPathfinding(text, pos, UserMissionListDescription); else if ('n' == text[pos + "#<".Length]) // 编辑任务变量 MainFormImpl.EditMissionVar(text, pos, CurrentEditMission, UserMissionListDescription); } catch (System.Exception ex) { Logger.LogFunctionError("MainForm.UserMissionListDescription_LinkClicked()", ex.Message); } }在LinkClicked中判断所点击的超链接是自动寻路还是任务变量,并将其传递给相应的对话框,并完成相应的逻辑工作,前面的HACK是为了全局替换所有相同的超链接,做到修改一处,自动更新其他超链接的效果。
这个是本任务编辑器中最复杂的部分,由于RichTextBox的内部数据结构是RTF格式,因此我们需要自己手动解析RTF文档,并将其转换成XML格式。
这里我采用的办法是以一行为一个解析单元,将行中的超链接先提取出来,并依次将字符串分割,分割效果如下图所示:
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:
