Qual o sistema de points que você está utilizando?

estou usando esse aqui

http://www.tibiaking.com/forum/topic/8183-system-pontos-p-points-system/

Testa:

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
local shopWindow = {}
local t = {
[2195] = {price = 15},
[2493] = {price = 25},
[8931] = {price = 100}
}
local onBuy = function(cid, item, subType, amount, ignoreCap, inBackpacks)
if t[item] and getPoints(cid) < t[item].price then
selfSay("você não tem "..t[item].price.." points", cid)
else
doPlayerAddItem(cid, item)
doPlayerRemovePoints(cid, t[item].price)
selfSay("aqui está seu item!", cid)
end
return true
end
if (msgcontains(msg, 'trade') or msgcontains(msg, 'TRADE'))then
for var, ret in pairs(t) do
table.insert(shopWindow, {id = var, subType = 0, buy = ret.price, sell = 0, name = getItemNameById(var)})
end
openShopWindow(cid, shopWindow, onBuy, onSell)
end
return true
end
npcHandler:setCallback(CALLBACK_MESSAGE_DEFAULT, creatureSayCallback)
npcHandler:addModule(FocusModule:new())

funcionou, está removendo os points agora

Reputado !

 

poderia me ajudar em outra coisa ??

queria que o npc comprasse os mesmos itens que ele vende por points, teria como fazer isso ?
