Lua What does this mean?

[Sherice]

Hi guys, as the title said, what does this error mean?:

Description:
data/npc/lib/npc.lua:73: attempt to index local 'message' <a nil value>
[Warning - NpcEvents::NpcEvents] Cannot load script,

blablabla

Anyone that can tell me what the problem is?


Thx, Sherice.

Well there is a problem in line 73 and that the local 'message' has a nil value (learning lua atm so can't tell u that much xd)

 

[Sherice]

Ok, thanks =)


[EDIT]: It says:

	local a, b = message:lower(), keyword:lower()

in npc.lua, so what's this?

 

[Reasembled]

[Sherice]

[Bintzer]

Ok:

local keywordHandler = KeywordHandler:new()
local npcHandler = NpcHandler:new(keywordHandler)
NpcSystem.parseParameters(npcHandler)
local talkState = {}
 
local Topic = {}

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 creatureSayCallback(cid, type, msg)
	local talkUser = NPCHANDLER_CONVBEHAVIOR == CONVERSATION_DEFAULT and 0 or cid
	if msgcontains(msg, "hi") or msgcontains(msg, "hello") then
		if getPlayerStorageValue(cid, storage) == 1 then
			npcHandler:say("Have you brought the loot?", cid)
			Topic[talkUser] = 1
		end
		npcHandler:addFocus(cid)
		return true
	end
	if(not npcHandler:isFocused(cid)) then
		return false
	end
end
	if msgcontains(msg, "mission") or msgcontains(msg, "guard") and getPlayerStorageValue(cid, storage) > 0 then
		if getPlayerStorageValue(cid, storage) < 1 then
			npcHandler:say("You wish to become a guard? Are you sure you want to become a guard?", cid)
			Topic[talkUser] = 1
			doSetPlayerStorageValue(cid, storage, 3)
		elseif getPlayerStorageValue(cid, storage) == 1 then

		elseif getPlayerStorageValue(cid, storage) == 2 then

			Topic[talkUser] = 0
		end
			end
			if msgcontains(msg, "yes") then
				if getPlayerStorageValue(cid, storage) == 3 then
			npcHandler:say("Alright, first, to become a guard, you have to prove your strength. Listen, lately, there have been some bandits lurking around the city, stealing stuff. I want you to take back the loot from them. Do you understand?", cid)
			Topic[talkUser] = 1
			doSetPlayerStorageValue(cid, storage, 4)
			end
			if msgcontains(msg, "yes") then

			else
				npcHandler:say("You dont have the items? Well, go and get them!", cid)
		end
		else

		end
		Topic[talkUser] = 0
	end
	return TRUE
end
 
npcHandler:setMessage(MESSAGE_WALKAWAY, "Good bye.")
npcHandler:setCallback(CALLBACK_MESSAGE_DEFAULT, creatureSayCallback)

It's an NPC quest script, yea I know, it's fucked up, I just modified it, didn't make it all by myself. Couldn't change it back to original so, I suck at lua scripting

 

[Sherice]

Bring U.M.P.

 

[Cronox]

change your folder lib
located in data/npc/lib
download and change..

lib npcs.rar - Speedy Share - upload your files here

 

[Sherice]

Well, now I get alot of "attempt to index global 'Keywordhandler' <a nil value>" bugs on all npc lua scripts.

 

[Cronox]

ohh its lib.. other version
your otserver what version is

 

[Sherice]

I dunno what version, I'll ask, and edit this post later.

[EDIT]: Im using a server based on DEV 0.4.

 

[Sherice]

B-u-m-p

 

[Cronox]

try this
lib.rar - Speedy Share - upload your files here

 

[Sherice]
