mudlet机器人开发除了基本的触发外，还可以使用lua脚本,客户端提供了大量的功能函数，这里列出常用和实用的部分，通过这些函数足以完善多数机器人脚本需求。
提示：函数除了写在lua脚本中，也都可以在命令行使用
lua func()测试，如：lua send("hp")。这里
lua是mudlet客户端内置扩展包提供的一个别名：
指令相关
send
send(command, showOnScreen)发送指令到游戏窗口，注意这个函数是直接发送command到游戏服务端，不会匹配客户端设置的别名，第二个参数showOnScreen 值为true/false，设置是否回显指令在屏幕上。
示例：
send("hp") --回显指令在屏幕上
send("score", false) --不显示指令在屏幕上
send("hi "..target) --使用变量sendAll
sendAll(list of things to send, [echo back or not])发送一系列指令到游戏，如果你是要快速行走，请用speedwalk()
示例：
sendAll("hi", "get all", "sleep") -- 发送3条指令到游戏中
speedwalk("w;s;n;e") --快速移动denyCurrentSend
denyCurrentSend()禁止send指令到游戏，可配合sysDataSendRequest事件使用，如下示例：
-- cancels all "eat hambuger" commands
function cancelEatHamburger(event, command)
if command == "eat hamburger" then
denyCurrentSend()
cecho("<red>Denied! Didn't let the command through.\n")
end
end
registerAnonymousEventHandler("sysDataSendRequest", "cancelEatHamburger")getCommandSeparator
getCommandSeparator()返回玩家配置文件正在使用的命令分隔符。
sendGMCP
sendGMCP(command)发送GMCP数据到服务器，对支持GMCP的服务端来说，可以有更多的操作
printCmdLine
printCmdLine([name], text)把text内容填在输入框中
内容显示相关
echo
echo([miniconsoleName or labelName], text)此函数在当前行的末尾追加文本。相似函数还有cecho(), decho(), hecho(), insertText(), cinsertText(), 当然lua自带的print也可以使用。
display
display(content)和echo类似的函数，在屏幕上显示文本，但和echo相比，还可以直接显示table，更适合做脚本调试。
debugc
debugc(content)这个是调试用的指令，内容不显示在屏幕上，而是显示在错误调试终端界面。
计时器
tempTimer
tempTimer(time, code to do[, repeating])enableTimer
enableTimer(name)disableTimer
disableTimer(name)killTimer
killTimer(id)-- or disable & enable a tempTimer you've made
timerID = tempTimer(10, [[echo("hi!")]])
-- it won't go off now
disableTimer(timerID)
-- it will continue going off again
enableTimer(timerID)remainingTime
remainingTime(timer id number or name)permTimer
permTimer(name, parent, seconds, lua code)用来创建永久性的计时器，注意计时器创建后默认未激活，需要使用enableTimer(name)激活。另外注意，mudlet中条目允许重名，所以多次运行permTimer会重复创建计时器，你可以使用exists()函数判断条目是否存在。
别名
tempAlias
aliasID = tempAlias(regex, code to do)创建一个临时别名，此别名在重新启动mudlet后丢失。
permAlias
permAlias(name, parent, regex, lua code)创建一个持久别名，该别名在重新启动Mudlet后保留，并显示在脚本编辑器中。
enableAlias
enableAlias(name)disableAlias
disableAlias(name)killAlias
killAlias(aliasID)触发
feedTriggers
feedTriggers(text[, dataIsUtf8Encoded = true])这个函数主要是用来测试触发，因为它发送的内容就像是游戏服务端发过来的内容一样，可以被客户端触发解析。
和Mudlet内置的这个别名效果一样。
模块与扩展包
getModules
getModules()获取客户端安装的模块，可以用来自动安装或卸载模块。getPackages()是功能类似的函数。
--Check if the module myTabChat is installed and if it isn't install it and enable sync on it
if not table.contains(getModules(),"myTabChat") then
installModule(getMudletHomeDir().."/modules/myTabChat.xml")
enableModuleSync("myTabChat")
endinstallModule
installModule(location)安装模块，只能是本地文件（远程文件可以先下载再安装），可以是XML, zip, mpackage文件。
uninstallModule
uninstallModule(name)reloadModule
reloadModule("generic-mapper")getPackages
getPackages()--Check if the generic_mapper package is installed and if so uninstall it
if table.contains(getPackages(),"generic_mapper") then
uninstallPackage("generic_mapper")
endinstallPackage
installPackage(location or url)安装扩展包，参数可以是本地文件，也可是网址（自动下载安装）
installPackage([[https://mud.ren/storage/mudren.mpackage.zip]])因为可以在线安装，使用这个函数可以很容易实现一个类似
apt、brew等包管理器的一键安装机器人的平台。玩家可以用mudlet连接炎黄MUD后输入mudren install guofu就会自动安装基础的郭府打工机器人。
uninstallPackage
uninstallPackage(name)getMudletHomeDir
getMudletHomeDir()返回当前配置目录
相关指令：getModuleInfo, getPackageInfo, setModuleInfo, setPackageInfo
事件处理相关
关于事件，可直接看这里：mudlet机器人脚本开发基础：事件系统
registerAnonymousEventHandler
registerAnonymousEventHandler(event name, functionReference, [one shot])注册匿名事件处理程序
killAnonymousEventHandler
killAnonymousEventHandler(handler id)注销注册的匿名事件处理程序
raiseEvent
raiseEvent(event_name, arg-1, … arg-n)raiseGlobalEvent
raiseGlobalEvent(event_name, arg-1, … arg-n)内容处理相关
selectString
selectString([windowName], text, number_of_match)replace
replace([windowName], with, [keepcolor])setLink
setLink([windowName], command, tooltip)如下示例，给移动方向增加可点击链接，玩家可直接点方向移动：
f
testResult = "successful"
-- old way:
echo("The test was "..testResult.."\n")
-- with f:
echo(f("The test was {testResult}\n"))
-- echoes "The test was successful\n"TTS(Text-to-Speech)
ttsSpeak
ttsSpeak("天啦,mudlet中可以发语音")把文字转为语音消息。
ttsQueue
ttsQueue("We begin with some text")
ttsQueue("And we continue it without interruption")相关指令：ttsSkip, ttsPause
其它杂项
alert
alert([seconds])让Mudlet图标在任务栏上闪烁提醒你
openWebPage
openWebPage(URL)打开一个网页
openWebPage("https://bbs.mud.ren")openUrl
openUrl (url)打开一个网页
openUrl("www.mudlet.org")connectToServer
connectToServer(host, port, [save])连接到指定的游戏服务器。
disconnect
disconnect()断开游戏连接
reconnect
reconnect()重连游戏
closeMudlet
closeMudlet()关闭游戏客户端
downloadFile
downloadFile(saveto, url)下载文件
showColors
showColors([columns], [filterColor], [sort])显示当前Mudlet中支持的颜色列表，颜色值存在color_table中，格式为： color_table.colorName = {r, g, b}
receiveMSP
receiveMSP(command)--Play a cow.wav media file stored in the media folder of the current profile. The sound would play twice at a normal volume.
receiveMSP("!!SOUND(cow.wav L=2 V=50)")
--Stop any SOUND media files playing stored in the media folder of the current profile.
receiveMSP("!!SOUND(Off)")
--Play a city.mp3 media file stored in the media folder of the current profile. The music would play once at a low volume.
--The music would continue playing if it was triggered earlier by another room, perhaps in the same area.
receiveMSP([[!!MUSIC(city.mp3 L=1 V=25 C=1)]])
--Stop any MUSIC media files playing stored in the media folder of the current profile.
receiveMSP("!!MUSIC(Off)")isActive
isActive(name, type)检测类型为type（触发、别名、定时器、按钮或脚本）的名称name是否是激活状态，如果是返回名称，否则返回0（注意Lua中0不是逻辑假，所有数字都是逻辑真，只有false和nil是逻辑假）
isPrompt
-- make a trigger pattern with 'Lua function', and this will trigger on every prompt!
return isPrompt()监测是否收到提示行，可以用来做一些自动的触发。注意：不推荐使用此函数，而是推荐直接使用匹配方式为提示的触发。
exists
exists(name, type)Tells you how many things of the given type exist.The type can be 'alias', 'trigger', 'timer', 'keybind' (Mudlet 3.2+), or 'script' (Mudlet 3.17+).
Note Note: This function is only for objects created in the script editor or via perm functions. You don't need it for temp functions and will not work for them.
