Need Help with npc [You need made a quest before be able deal with him]

[askarda]

Hi there, I need npc script that is like this..

To be able deal with an npc, you need have done an quest (Playerstorage)

This is one of my travel scripts atm

local keywordHandler = KeywordHandler:new()
        local npcHandler = NpcHandler:new(keywordHandler)
        NpcSystem.parseParameters(npcHandler)
        
        
        
        -- OTServ event handling functions start
        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
        -- OTServ event handling functions end
        
        
        -- Don't forget npcHandler = npcHandler in the parameters. It is required for all StdModule functions!
        local travelNode = keywordHandler:addKeyword({'venore'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'Do you want to sail to Venore for 60 gold coins?'})
        	travelNode:addChildKeyword({'yes'}, StdModule.travel, {npcHandler = npcHandler, premium = true, level = 0, cost = 60, destination = {x=32952, y=32022, z=6} })
        	travelNode:addChildKeyword({'no'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, reset = true, text = 'Then stay here!'})
        
	local travelNode = keywordHandler:addKeyword({'port hope'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'Do you want to sail to Port Hope for 180 gold coins?'})
        	travelNode:addChildKeyword({'yes'}, StdModule.travel, {npcHandler = npcHandler, premium = true, level = 0, cost = 180, destination = {x=32527, y=32784, z=6} })
        	travelNode:addChildKeyword({'no'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, reset = true, text = 'Then stay here!'})
    
        keywordHandler:addKeyword({'sail'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'I can take you to Venore, Port Hope and Ankrahmun.'})
        keywordHandler:addKeyword({'job'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'I am the captain of this ship.'})
        keywordHandler:addKeyword({'travel'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'I can only take you to Venore, Port Hope and Ankrahmun.'})
        -- Makes sure the npc reacts when you say hi, bye etc.
        npcHandler:addModule(FocusModule:new())

and this is a seller script:

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



-- OTServ event handling functions start
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
-- OTServ event handling functions end

local shopModule = ShopModule:new()
npcHandler:addModule(shopModule)

shopModule:addBuyableItem({'light wand', 'lightwand'}, 					2163, 500, 		'magic light wand')
shopModule:addBuyableItem({'mana fluid', 'manafluid'}, 					2006, 50, 	7, 	'mana fluid')
shopModule:addBuyableItem({'life fluid', 'lifefluid'}, 					2006, 80, 	10,	'life fluid')

shopModule:addBuyableItem({'great fireball rune', 'great fireball rune'}, 						2304, 130, 2, 	'great fireball rune')
shopModule:addBuyableItem({'explosion rune', 'explosion rune'}, 							2313, 300, 3, 	'explosion rune')
shopModule:addBuyableItem({'ultimate healing rune', 'ultimate healing rune'}, 					2273, 175, 1, 	'ultimate healing rune')
shopModule:addBuyableItem({'sudden death rune', 'sudden death rune'}, 						2268, 325, 1,	'sudden death rune')
