Gostaria de um script de npc que só mude a vocação se o player tiver tal storage e o item necessário.

 

Storage: qualquer uma depois mudo

 

Item: qualquer um depois mudo.

exchanger.lua (data/npc/scripts):
 

local tab = {
[1] = {voc = 5, item = {1234, 5}, sto = {12345, 1}, -- [paraqualvocID] = {voc = novavocID, item {itemID, count}, sto = {storage, valordastorage}},
[2] = {voc = 6, item = {1234, 5}, sto = {12345, 1},
[3] = {voc = 7, item = {1234, 5}, sto = {12345, 1},
[4] = {voc = 8, item = {1234, 5}, sto = {12345, 1}
}

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, 'favor')) then
        talkState[talkUser] = 1
        selfSay('You need to bring me '..tab[getPlayerVocation].item[2]..' '..getItemNameById(tab[getPlayerVocation].item[1])..' and then I can {change} your vocation.', cid)
    elseif(msgcontains(msg, 'change') and talkState[talkUser] == 1) then
        talkState[talkUser] = 2
        selfSay('Are you sure you want to do this change?', cid)
    elseif(msgcontains(msg, 'yes') and talkState[talkUser] == 2) then
        if(getPlayerVocation(cid) ~= tab[getPlayerVocation(cid)].voc) then
            if(tab[getPlayerVocation(cid)] and getPlayerStorageValue(cid, tab[getPlayerVocation(cid)].sto[1]) > tab[getPlayerVocation(cid)].sto[2]) then
                if(doPlayerRemoveItem(cid, tab[getPlayerVocation(cid)].item[1], tab[getPlayerVocation(cid)].item[2]) == true) then
                    talkState[talkUser] = 0
                    doPlayerSetVocation(cid, tab[getPlayerVocation(cid)].voc)
                    doSendMagicEffect(getThingPos(cid), CONST_ME_GIFT_WRAPS)
                else
                    talkState[talkUser] = 0
                    selfSay('You do not have the required items.', cid)
                end
            else
                talkState[talkUser] = 0
                selfSay('You can not change your vocation.', cid)
            end
        else
            talkState[talkUser] = 0
            selfSay('You already have changed your vocation.', cid)
        end
    elseif(msgcontains(msg, 'no')) then
        talkState[talkUser] = 0
        selfSay('Sure. Goodbye!', cid)
    end
    return true
end

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

Exchanger.xml (data/npc):

Em 25/10/2014 em 03:35, Wise disse:

selfSay('You need to bring me '..tab[getPlayerVocation].item[2]..' '..getItemNameById(tab[getPlayerVocation].item[1])..' and then I can {change} your vocation.', cid)

 

creio que o unico erro desse script seja essa linha
troca os "getPlayerVocation" pra getPlayerVocation(cid) que ja vai funcionar @matheuspeixoto12
