[Encerrado] [SCRIPT] keywordHandler

[PobrePreto 5]

Boa Noite, Tenho um OTServer 8.60, Recentemente Compilei ele em uma VPS Ubuntu 14.04 Com uma Source OTXServer... Só que Depois que compilei venho me deparando com muitos e muitos Erros...

Um Deles é... 

[Error - NpcScript Interface]
data/npc/scripts/Markwin.lua
Description:
data/npc/scripts/Markwin.lua:1: attempt to index global 'KeywordHandler' (a nil value)
[Warning - NpcEvents::NpcEvents] Cannot load script: data/npc/scripts/Markwin.lua

Script do NPC:

 

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

npcHandler:addModule(FocusModule:new())

Meu keywordhandler:

-- Advanced NPC System (Created by Jiddo),
-- Modified by TheForgottenServer Team.

if(KeywordHandler == nil) then
	BEHAVIOR_SIMPLE = 1 -- Does not support nested keywords. If you choose this setting you must use a variable such as 'talkState' to keep track of how to handle keywords.
	BEHAVIOR_NORMAL = 2 -- Default behvaior. If a sub-keyword is not found, then the root is searched, not the parent hierarchy,
	BEHAVIOR_NORMAL_EXTENDED = 3 -- Same as BEHAVIOR_NORMAL but it also searches through the last node's parent.
	BEHAVIOR_COMPLEX = 4 -- Extended behavior. It a sub-keyword is not found, then the entire keyword hierarchy is searched upwards until root is reached.

	-- BEHAVIOR_NORMAL_EXTENDED is recommended as it (probably) mimics the behavior of real Tibia's NPCs the most.
	--		However, you are strongly recommended to test some (or all) other settings as well as it might suit you better.
	--		Also note that not much difference can be seen with the different settings unless you have a npc with a quite heavy
	--		nestled keyword hierarchy.
	-- Note: BEHAVIOR_SIMPLE should not be used unless you have any special reason to do so as it forces you to keep track of talkStates etc.
	--		This was pretty much the method used in the 2.0x versions of this system. It is here mainly for compability issues.
