With the new NPC system of TFS Im not able to make a NPC that changes a certain amount of items for a new item:

Code: 
        elseif msgcontains(msg, 'yes') and talk_state == 1 then
            if getPlayerItemCount(cid,2487) >= 1 then
                if doPlayerTakeItem(cid,2487,1) == 0 then
                    selfSay('Here you are.')
                    doPlayerAddItem(cid,5887,1)
                end
            else
                selfSay(hasNoMsg)
            end
            talk_state = 0[/php]

Someone could make one with the new system with this one:

[php]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())

Thanks :)

try this

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 creatureSayCallback(cid, type, msg)
	if(not npcHandler:isFocused(cid)) then
		return FALSE
	end
	
	
	
	if msgcontains(msg, 'SECRET KEYWORD!!! (what to write to execute it)') then
		npcHandler:say("Are you sure :o?", cid)
		talkState = 1
	elseif talkState == 1 then
		if doPlayerTakeItem(cid,2487,1) == 0 and msgcontains(msg, 'yes') then
            npcHandler:say('Here you are.', cid)
            doPlayerAddItem(cid,5887,1)
		else
			npcHandler:say('Come back with a bloody crown armor or I will kill you!', cid)
        end
		talkState = 0
	end
	
	return TRUE
end

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

Here it goes:
Code: 
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(not npcHandler:isFocused(cid)) then
		return false
	end

	local talkUser = NPCHANDLER_CONVBEHAVIOR == CONVERSATION_DEFAULT and 0 or cid

	if(msgcontains(msg, 'royal steel')) then
		if(getPlayerItemCount(cid, 2487) >= 1) then
			selfSay('Do you want to trade a crown armor for a royal steel?', cid)
			talkState[talkUser] = 1
		else
			selfSay('I need a crown armor to trade with you for a royal steel.', cid)
		end
	elseif(msgcontains(msg, 'yes') and talkState[talkUser] == 1) then
		if(getPlayerItemCount(cid, 2487) >= 1) then
			if(doPlayerTakeItem(cid, 2487, 1) == TRUE) then
				doPlayerGiveItem(cid, 5887, 1)
				selfSay('Here you are.', cid)
			end
		else
			selfSay('Sorry, you don\'t have requested item.', cid)
		end
		talkState[talkUser] = 0
	elseif(msgcontains(msg, 'no') and isInArray({1}, talkState[talkUser]) == TRUE) then
		talkState[talkUser] = 0
		selfSay('Ok then.', cid)
	end

	return TRUE
end

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

Thanks man, the correct one and easyest is:

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 creatureSayCallback(cid, type, msg)
    if(not npcHandler:isFocused(cid)) then
        return FALSE
    end
    
    
    
    if msgcontains(msg, 'SECRET KEYWORD!!! (what to write to execute it)') then
        npcHandler:say("Are you sure :o?", cid)
        talkState = 1
    elseif talkState == 1 then
        if doPlayerTakeItem(cid,2487,1) == 0 and msgcontains(msg, 'yes') then
            npcHandler:say('Here you are.', cid)
            doPlayerAddItem(cid,5887,1)
        else
            npcHandler:say('Come back with a bloody crown armor or I will kill you!', cid)
        end
        talkState = 0
    end
    
    return TRUE
end

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

Click to expand...

This won't work with npc chat due to queue, talkState has to be a table.

This should make it work try it out.

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 creatureSayCallback(cid, type, msg)

    if(npcHandler.focus ~= cid) then
        return false
    end

local no_item = You dont have the correct items ----If player has wrong item
local giveid = 1890  ---id of the item that needs to be added
local item1 = 1890 -----id of the item that needs to get removed
local item2 = 1890 -----id of the item that needs to get removed local item3 = 1890 -----id of the item that needs to get removed
local item4 = 1890 -----id of the item that needs to get removed
local item5 = 1890 -----id of the item that needs to get removed if msgcontains(msg,'trade') then
selfSay('Would u like to trade items with me?')
if msgcontains(msg, 'yes') then	
         if doPlayerRemoveItem(cid,item1,1) and doPlayerRemoveItem(cid,item2,1) and doPlayerRemoveItem(cid,item3,1) and doPlayerRemoveItem(cid,item4,1) and doPlayerRemoveItem(cid,item5,1) == TRUE then
            doPlayerAddItem(cid,giveid,1)
                end
            else
                selfSay(no_item)
            end

        elseif msgcontains(msg, 'no') and (talk_state >= 1 then
            selfSay('Get out of mine sight!')
            talk_state = 0
            end
 
        return true
           end
 
npcHandler:setCallback(CALLBACK_MESSAGE_DEFAULT, creatureSayCallback)
npcHandler:addModule(FocusModule:new())
