[Dubler]

Please edit my script:

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

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)
     if msgcontains(msg, 'mission') then
              if getCreatureStorage(cid, 17001) == 1 then
                    selfSay('Hmm... grenhorn... I know! Find and bring me a firebug. Look for hole in ground on souther island.')
                    doCreatureSetStorage(cid, 17001, 2)
              else
                    selfSay('Lol?! WTF?' .. getCreatureStorage(cid, 17001))
                    talk_state = 0
              end
     elseif msgcontains(msg, 'noob') then
              selfSay("Fuck YOU!!!!!!!!")
              talk_state = 0
     end
return true
end
npcHandler:setCallback(CALLBACK_MESSAGE_DEFAULT, creatureSayCallback)
npcHandler:addModule(FocusModule:new())
