Hey,

I want to use advanced lua scripts in my NPCs, but I don't know anything about LUA,
any idea how can I use this to make the NPC answer to Keys and reply with reply?

Code: 
local Messages = {
     {Key = "name", Reply = "I'm Joe."},
     {Key = "job", Reply = "I'm a merchant."}
}

You can do this in the XML, it will give the same effect.

LUA: 
<parameter value="1" key="module_keywords"/> 
<parameter value="name;job;help;something;" key="keywords"/>
<parameter key="keyword_reply1" value="I am Joe." />
<parameter key="keyword_reply2" value="I am a merchant." />
<parameter key="keyword_reply3" value="I can help you. " />
<parameter key="keyword_reply4" value="Right." />

I know, but parameters in XML is pretty deprecated, it's missing talking delays too.

There are two ways of doing that, here's the full script of an example NPC using both modes:

-- First Mode --

Code: 
-- MODE 1 --

local focuses, controlId = {}, 3586

local talkState = {}

function onCreatureDisappear(cid)
    if isFocused(cid, focuses) then
     removeFocus(cid, focuses)
        if isPlayer(cid) then
         closeShopWindow(cid)
        end
    end
end

local Messages = {
     {Key = "name", Reply = "I'm Joe."},
     {Key = "job", Reply = "I'm a merchant."}
}


function onCreatureSay(cid, type, msg)
 local travelWindow = {}
    if msgcontains(msg, "hi", "hello") and not isFocused(cid, focuses) and getDistanceToCreature(cid) < 4 then
       addFocus(cid, focuses)
       selfSay("Hiho " .. getCreatureName(cid) .. ", i'm the test npc.", cid)
     
    elseif msgcontains(msg, "bye") then
          talkState[cid] = nil
          selfSay("Goodbye!", cid)
          closeShopWindow(cid)
          removeFocus(cid, focuses)
          lookAtFocus(focuses)
       
    else
         for _,v in pairs(Messages) do
            if v.Key == string.lower(msg) then
               selfSay(v.Reply, cid)
            end
         end
    end
end

function onThink()
    for _, focus in pairs(focuses) do
        if not isCreature(focus) then
         removeFocus(focus, focuses)
        else
         local distance = getDistanceTo(focus) or 5
            if distance > 4 then
                selfSay("HOW DARE YOU LEAVE WITHOUT SAYING GOOD BYE!? THUNDERST... kidding haha, good luck traveller!", focus)
                closeShopWindow(focus)
                removeFocus(focus, focuses)
            end
        end
    end
    lookAtFocus(focuses)
end

            if distance > 4 then
                selfSay("HOW DARE YOU LEAVE WITHOUT SAYING GOOD BYE!? THUNDERST... kidding haha, good luck traveller!", focus)
