[DanneZ]

I used this npc script made by Cykotitan, but i want it like if u answer all questions correctly you get an storage.

Script by Cykotitan.

local keywordHandler = KeywordHandler:new()
local npcHandler = NpcHandler:new(keywordHandler)
NpcSystem.parseParameters(npcHandler)
 
local Topic = {}
local conv = {
	{
		[1] = "What genre are tibia?"

	},
	{
		[1] = "mmorpg"

	}
}
 
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 greetCallback(cid)
	local talkUser = NPCHANDLER_CONVBEHAVIOR == CONVERSATION_DEFAULT and 0 or cid
	Topic[talkUser] = 0
	return true
end
 
function creatureSayCallback(cid, type, msg)
 
	if(not npcHandler:isFocused(cid)) then
		return false
	end
	local talkUser = NPCHANDLER_CONVBEHAVIOR == CONVERSATION_DEFAULT and 0 or cid
 
	if Topic[talkUser] > 0 then
		if msgcontains(msg, conv[2][Topic[talkUser]]) then
		          local storage = 133341
			npcHandler:say("Congratulations, you have answered correctly!", cid)
			npcHandler:say("Now go to the leader and get your reward!", cid)
			setPlayerStorageValue(cid, storage, 1)
		else
			npcHandler:say("Sorry, but that wasn't the correct answer.", cid)
		end
		Topic[talkUser] = 0
	elseif msgcontains(msg, "question") then
		local random = math.random(#conv[1])
		npcHandler:say(conv[1][random], cid)
		Topic[talkUser] = random
	end
	return true
end
 
npcHandler:setCallback(CALLBACK_GREET, greetCallback)
npcHandler:setCallback(CALLBACK_MESSAGE_DEFAULT, creatureSayCallback)
npcHandler:addModule(FocusModule:new())
