Lua [fix] NPC "THE ORACLE"

[Lontra]

It's almost the same that the oracle... but i want an oracle diferente... he just "give" the vocation to the player...
and i cant finish with "yes" after say your vocation. Anyway... heres the script:

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 oracle(cid, message, keywords, parameters, node)
    if(not npcHandler:isFocused(cid)) then
        return false
    end

    local vocNode = node:getParent()

    local vocation = vocNode:getParameters().vocation

    if(destination ~= nil and vocation ~= nil and town ~= nil) then
        if(getPlayerLevel(cid) < parameters.level) then
            npcHandler:say('You must first reach level ' .. parameters.level .. '!', cid)
            npcHandler:resetNpc()
        else
            if(getPlayerVocation(cid) > 0) then
                npcHandler:say('Sorry, You already have a vocation!')
                npcHandler:resetNpc()
            else
                doPlayerSetVocation(cid, vocation)
                npcHandler:resetNpc()

                local tmp = getCreaturePosition(cid)
                doTeleportThing(cid, destination)
                doSendMagicEffect(tmp, CONST_ME_POFF)
                doSendMagicEffect(destination, CONST_ME_TELEPORT)
            end
        end
    end

    return true
end

function greetCallback(cid)
    if(getPlayerLevel(cid) < 8) then
        npcHandler:say('COME BACK WHEN YOU GROW UP, CHILD!')
        return false
    else
        return true
    end
end
npcHandler:setCallback(CALLBACK_GREET, greetCallback)
npcHandler:setMessage(MESSAGE_GREET, 'Hello |PLAYERNAME|. Are you prepared to face your destiny?')

local yesNode = KeywordNode:new({'yes'}, oracle, {level = 8})
local noNode = KeywordNode:new({'no'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, moveup = 1, text = 'Then what vocation do you want to become?'})

local node1 = keywordHandler:addKeyword({'yes'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'So what vocation do you wish to become? {Sorcerer}, {druid}, {paladin} or {knight}?'})

local node2 = node1:addChildKeyword({'sorcerer'}, StdModule.say, {npcHandler = npcHandler, vocation = 1, onlyFocus = true, text = 'So, you wish to be a powerful magician? Are you sure about that? This decision is irreversible!'})
           
            node2:addChildKeywordNode(yesNode)
            node2:addChildKeywordNode(noNode)
        node2 = node1:addChildKeyword({'druid'}, StdModule.say, {npcHandler = npcHandler, vocation = 2, onlyFocus = true, text = 'Are you sure that a druid is what you wish to become? This decision is irreversible!'})
            node2:addChildKeywordNode(yesNode)
            node2:addChildKeywordNode(noNode)
        node2 = node1:addChildKeyword({'paladin'}, StdModule.say, {npcHandler = npcHandler, vocation = 3, onlyFocus = true, text = 'A ranged marksman. Are you sure? This decision is irreversible!'})
            node2:addChildKeywordNode(yesNode)
            node2:addChildKeywordNode(noNode)
        node2 = node1:addChildKeyword({'knight'}, StdModule.say, {npcHandler = npcHandler, vocation = 4, onlyFocus = true, text = 'A mighty warrior. Is that your final decision? This decision is irreversible!'})
            node2:addChildKeywordNode(yesNode)
            node2:addChildKeywordNode(noNode)
keywordHandler:addKeyword({'no'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'Then come back when you are ready.'})

npcHandler:addModule(FocusModule:new())
