Is There a way to make a npc that you need 100 metal spikes(id 11208) and can trade them in for a health stone{id 11220} or mana skull(id 2229)
Thanks,
Tjay

~bump~
If someone has some similar to it ill can probably tweak it.
Thanks Tjay

Do you want to use the actual "trade" window of the npc? Or can it be like saying: "buy healthstone"?

Tjay · Jul 14, 2011

It Really wouldnt matter. Preferrably the trade window.

ond · Jul 14, 2011

Lua:

if getPlayerItemCount(cid, 11208) >= 100 then
	doPlayerRemoveItem(cid, 11208, 100)
	doPlayerAddItem(cid, 11220, 1) -- Or doPlayerAddItem(cid, 2229, 1)
end

Something like that (the function)

Basicly but i ended up changing it to just a npc that will add health or mana for 100 metal spikes but for some reason its not adding mana or health..

Code:

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
 
function buyMana(cid, message, keywords, parameters, node)
		if doPlayerRemoveItem(cid, 11208, 100) then
		setCreatureMaxMana(cid, getCreatureMaxMana(cid)+1000)
		npcHandler:say("Thank you.", cid)
		npcHandler:releaseFocus(cid)
	else
		npcHandler:say("You don't have items required yet...", cid)
		npcHandler:releaseFocus(cid)
	end
	return true
end
 
function buyHealth(cid, message, keywords, parameters, node)
		if doPlayerRemoveItem(cid, 11208, 100) then
		setCreatureMaxHealth(cid, getCreatureMaxHealth(cid)+1000)
		npcHandler:say("Thank you.", cid)
		npcHandler:releaseFocus(cid)
	else
		npcHandler:say("You don't have items required yet..", cid)
		npcHandler:releaseFocus(cid)
	end
	return true
end
 
local node1 = keywordHandler:addKeyword({'mana'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = "Do you want to buy 1000 mana for 100 metal spikes?"})
	node1:addChildKeyword({'yes'}, buyMana, {npcHandler = npcHandler, onlyFocus = true, reset = true})
	node1:addChildKeyword({'no'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'Ok then.', reset = true})
 
local node2 = keywordHandler:addKeyword({'health'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = "Do you want to buy 1000 health for 100 metal spikes?"})
	node2:addChildKeyword({'yes'}, buyMana, {npcHandler = npcHandler, onlyFocus = true, reset = true})
	node2:addChildKeyword({'no'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'Ok then.', reset = true})
 
npcHandler:addModule(FocusModule:new())

I have this im not getting any errors in console. But its not working it will take the spikes away but it does add to ur mana or ur hp

Try this:

Lua:

local keywordHandler = KeywordHandler:new()
local npcHandler = NpcHandler:new(keywordHandler)
NpcSystem.parseParameters(npcHandler)
 
local Topic = 0 
 
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)
	Topic = 0
	return true
end 

npcHandler:setMessage(MESSAGE_GREET, "Greetings, |PLAYERNAME|.")
npcHandler:setMessage(MESSAGE_WALKAWAY, "How rude!")
npcHandler:setMessage(MESSAGE_FAREWELL, "Bye.")
 
npcHandler:setCallback(CALLBACK_GREET, greetCallback) 
 
if msgcontains(msg, "mana") then
	npcHandler:say("Do you want to buy 1000 mana for 100 metal spikes?.", cid)
		Topic = 1
	
elseif msgcontains(msg, "health") then
	npcHandler:say("Do you want to buy 1000 health for 100 metal spikes?.", cid)
		Topic = 2


	elseif Topic == 1 then
		if msgcontains(msg, 'yes') then
			if getPlayerItemCount(cid, 11208) >= 100 then
				doPlayerRemoveItem(cid, 11208, 100)
				setCreatureMaxMana(cid, getCreatureMaxMana(cid)+1000)
				npcHandler:say("Thank you.", cid)
				npcHandler:releaseFocus(cid)
				Topic = 0
			else
				npcHandler:say("You don't have items required yet...", cid)
				npcHandler:releaseFocus(cid)
                                Topic = 0
			end
		end	

	elseif Topic == 2 then
		if msgcontains(msg, 'yes') then
			if getPlayerItemCount(cid, 11208) >= 100 then
				doPlayerRemoveItem(cid, 11208, 100)
				setCreatureMaxMana(cid, getCreatureMaxHealth(cid)+1000)
				npcHandler:say("Thank you.", cid)
				npcHandler:releaseFocus(cid)
				Topic = 0
			else
				npcHandler:say("You don't have items required yet...", cid)
				npcHandler:releaseFocus(cid)
                                Topic = 0
			end
		end			
			
			

		end
	return TRUE
end

npcHandler:setCallback(CALLBACK_MESSAGE_DEFAULT, creatureSayCallback)
npcHandler:addModule(FocusModule:new())
