Olá, eu estou sofrendo com um bug envolvendo o shop do meu server. Consegui fazer o Shop funcionar, mas o player está recebendo infinitamente o item comprado. Já vi este bug sendo tratado em muitos lugares mas ninguém dá uma solução definitiva. Estou usando um server 8.60, com o Gesior versão 0.3.6 r.70, Xampp 1.7.3.

 

O erro que eu recebo (a cada vez que o char recebe o item) é o seguinte:

[14/02/2015 15:56:38] [Error - GlobalEvent Interface] 
[14/02/2015 15:56:38] data/globalevents/scripts/shop.lua:onThink

[14/02/2015 15:56:38] [Error - GlobalEvents::think] Couldn't execute event: shop

Aqui ta o meu script shop.lua:

 

-- ### CONFIG ###
-- message send to player by script "type" (types you can check in "global.lua")
SHOP_MSG_TYPE = 19
-- time (in seconds) between connections to SQL database by shop script
SQL_interval = 30
-- ### END OF CONFIG ###

action = tostring(result_plr:getDataString("action"))

cid = getCreatureByName(tostring(result_plr:getDataString("name")))
if isPlayer(cid) == TRUE then

else
items_weight = container_count * getItemWeightById(itemtogive_id, itemtogive_count)
end
full_weight = items_weight + container_weight

end
end
local free_cap = getPlayerFreeCap(cid)
if full_weight <= free_cap then
if add_item_type == 'container' then
local new_container = doCreateItemEx(container_id, 1)
local iter = 0
while iter ~= container_count do
local new_item = doCreateItemEx(itemtogive_id, itemtogive_count)
received_item = doPlayerAddItemEx(cid, new_item)
iter = iter + 1
end
received_item = doPlayerAddItemEx(cid, new_container)
else
local new_item = doCreateItemEx(itemtogive_id, itemtogive_count)
received_item = doPlayerAddItemEx(cid, new_item)
end
if received_item == RETURNVALUE_NOERROR then
doPlayerSendTextMessage(cid, SHOP_MSG_TYPE, 'You received >> '.. add_item_name ..' << from OTS shop.')
db.executeQuery("DELETE FROM `z_ots_comunication` WHERE `id` = " .. id .. ";")
db.executeQuery("UPDATE `z_shop_history_item` SET `trans_state`='realized', `trans_real`=" .. os.time() .. " WHERE id = " .. id .. ";")
else
doPlayerSendTextMessage(cid, SHOP_MSG_TYPE, '>> '.. add_item_name ..' << from OTS shop is waiting for you. Please make place for this item in your backpack/hands and wait about '.. SQL_interval ..' seconds to get it.')
end
else
doPlayerSendTextMessage(cid, SHOP_MSG_TYPE, '>> '.. add_item_name ..' << from OTS shop is waiting for you. It weight is '.. full_weight ..' oz., you have only '.. free_cap ..' oz. free capacity. Put some items in depot and wait about '.. SQL_interval ..' seconds to get it.')
end
end
if not(result_plr:next()) then
break
end
end
result_plr:free()
end
return TRUE
end 

 

Desconfio que esse comando nas linhas 57 e 58, db.executeQuery, esteja errado. Já tentei outros comandos (inclusive db.query) e nada funciona, tudo retorna o mesmo erro. Ele não está deletando a entrada no z_ots_comunication e nem mudando a coluna trans_state no z_shop_history_item para realized. Também tentei mudar a pasta lib do server pela de outro server, mas o erro se mantém.

 

Alguém tem uma solução?

Tenta assim:

local SHOP_MSG_TYPE = MESSAGE_EVENT_ORANGE
local SQL_interval = 30
 
function onThink(interval, lastExecution)
    local result_plr = db.getResult("SELECT * FROM z_ots_comunication WHERE `type` = 'login';")
    if(result_plr:getID() ~= -1) then
        while(true) do
            local id = tonumber(result_plr:getDataInt("id"))
            local action = tostring(result_plr:getDataString("action"))
            local delete = tonumber(result_plr:getDataInt("delete_it"))
            local cid = getCreatureByName(tostring(result_plr:getDataString("name")))
            if isPlayer(cid) then
                local itemtogive_id = tonumber(result_plr:getDataInt("param1"))
                local itemtogive_count = tonumber(result_plr:getDataInt("param2"))
                local container_id = tonumber(result_plr:getDataInt("param3"))
                local container_count = tonumber(result_plr:getDataInt("param4"))
                local add_item_type = tostring(result_plr:getDataString("param5"))

                    end
                    full_weight = items_weight + container_weight
                else
                    full_weight = getItemWeightById(itemtogive_id, itemtogive_count)
                    if isItemRune(itemtogive_id) == TRUE then
                        full_weight = getItemWeightById(itemtogive_id, 1)
                    else
                        full_weight = getItemWeightById(itemtogive_id, itemtogive_count)
                    end
                end
                local free_cap = getPlayerFreeCap(cid)
                if full_weight <= free_cap then
                    if add_item_type == 'container' then
                        local new_container = doCreateItemEx(container_id, 1)
                        local iter = 0
                        while iter ~= container_count do
                            doAddContainerItem(new_container, itemtogive_id, itemtogive_count)
                            iter = iter + 1
                        end
                        received_item = doPlayerAddItemEx(cid, new_container)
                    else
                        local new_item = doCreateItemEx(itemtogive_id, itemtogive_count)
                        doItemSetAttribute(new_item, "description", "Este item foi comprado pelo player: ".. getPlayerName(cid) ..".")
                        doItemSetAttribute(new_item, "aid", getPlayerGUID(cid)+10000)
                        received_item = doPlayerAddItemEx(cid, new_item)
                    end
                    if received_item == RETURNVALUE_NOERROR then
                        doPlayerSendTextMessage(cid, SHOP_MSG_TYPE, 'Voce recebeu >> '.. add_item_name ..' << do Underworld SHOP.')
                        db.query("DELETE FROM `z_ots_comunication` WHERE `id` = " .. id .. ";")
                        db.query("UPDATE `z_shop_history_item` SET `trans_state`='realized', `trans_real`=" .. os.time() .. " WHERE id = " .. id .. ";")
                    else
                        doPlayerSendTextMessage(cid, SHOP_MSG_TYPE, 'Voce nao tem cap ou espaço para receber o item >> '.. add_item_name ..' << , o SHOP esta esperando voce ter cap para entregar o item!')
                    end
                else
                    doPlayerSendTextMessage(cid, SHOP_MSG_TYPE, 'Voce nao tem cap ou espaço para receber o item >> '.. add_item_name ..' << , o SHOP esta esperando voce ter cap para entregar o item!')
                end
            end
            if not(result_plr:next()) then
                break
            end
        end
        result_plr:free()
    end
    return true
end

Deu um erro ligeiramente diferente, mas é praticamente o mesmo:

Tudo indica que seu servidor não possui a função db.query para executar consultas SQL no banco de dados, o que é por si só é muito estranho.

 

Qual a versão do Tibia do servidor? Usa The Forgotten Server, se sim qual revisão?

Garou tem razão, esse parece ser o único motivo para não estar funcionando.
