[Lua] How do I get the answer that I gave to the NPC?

[Jack Parsons]

I'm having difficulties finding how to access the answer that I gave to the NPC. Let us use this script as an example:

local keywordHandler = KeywordHandler:new()
local npcHandler = NpcHandler:new(keywordHandler)
NpcSystem.parseParameters(npcHandler)

function onCreatureAppear(cid)
    npcHandler:onCreatureAppear(cid)
end
function onCreatureDisappear(cid)
    npcHandler:onCreatureDisappear(cid)
end
function onCreatureSay(cid, type, msg)
    npcHandler:onCreatureSay(cid, type, msg)
end
function onThink()
    npcHandler:onThink()
end

function tell(cid, message, keywords, parameters, node)
    local npcHandler = parameters.npcHandler
    if npcHandler == nil then
        error("tell called without any npcHandler instance.")
    end
    if not npcHandler:isFocused(cid) then
        return false
    end
    npcHandler:say(parameters.text, cid)
    npcHandler:resetNpc(cid)
    return true
end

local node = keywordHandler:addKeyword({'creature'}, tell, {npcHandler = npcHandler, onlyFocus = true, text = 'Tell me the name of a {creature}, and I'll repeat it to you...'})
node:addChildKeyword({ANSWER_THAT_I_GAVE}, someFunc, {})
npcHandler:addModule(FocusModule:new())

Pretty straightfoward. As you can see, I say "creature" to the NPC and that triggers the function tell, and then he just asks me to say the name of some creature. The problem is, I want to use the name that I gave him as an answer to be the trigger-word for the next function. How can I access the answer that I gave to the NPC through the node that is returned by the addKeyword()?

I've had people help me with this in the past, and I've used it a couple of times the same way.
I'm not certain if there is a better way or not. There probably is, but I've found it works for me.

Use a table to hold the value 'msg', and have the table updated somewhere in the script.

You might be able to trick the keywordhandler with this:

node:addChildKeyword({"."}, someFunc, {})

why dont you just make a script for this npc and thread like that

if msg == "creature_name" then

here is a example of a bless npc I made a couple weeks ago

I eventually solved it doing exactly that (Parsing / filtering the message). I've posted the NPC I was creating already: https://otland.net/threads/tfs-1-0-summon-any-creature-in-the-game-for-a-bloody-price.241608/

I've used a little split function:

function split(inputstr, sep)
    if sep == nil then
        sep = "%s"
    end
    local t={} ; i=1
    for str in string.gmatch(inputstr, "([^"..sep.."]+)") do
        t[i] = str
        i = i + 1
    end
    return t
end

In that way, I've just passed the message as an argument and got a table (And then, it was easy to get what I've said accessing the indexes).

function Answer(cid, message, keywords, parameters, node)
    local npcHandler = parameters.npcHandler
    if npcHandler == nil then
        error("Answer called without any npcHandler instance.")
    end

    if not npcHandler:isFocused(cid) then
        return false
    end

    npcHandler:say("You said " .. message, cid)
    return true
end

local node = keywordHandler:addKeyword({'keyword'}, tell, {npcHandler = npcHandler, onlyFocus = true, text = 'Say something..'})
    node:addChildKeyword({''}, Answer, {npcHandler = npcHandler})
