Eu estou usando tfs 0.4, 8.7, eu procurei mas não encontrei, como eu faço um npc abrir diferentes janelas de trade de acordo com a vocation do player, se knight, abre o trade com itens de knight, se rp, abre o trade com itens de rp, alguém tem algum npc assim?

é todos os npc's ou um npc especifico?

Um específico

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
