	ProtocolGame.registerExtendedOpcode(26,

  inventoryButton:destroy()
end

function refresh()
  local player = g_game.getLocalPlayer()
  for i=InventorySlotFirst,InventorySlotLast do
    if g_game.isOnline() then
      onInventoryChange(player, i, player:getInventoryItem(i))
    else
      onInventoryChange(player, i, nil)
    end
  end
end

function toggle()
refresh()
  if inventoryButton:isOn() then
    inventoryWindow:close()
    inventoryButton:setOn(false)
  else
    inventoryWindow:open()
    inventoryButton:setOn(true)
  end
end

function onMiniWindowClose()
  inventoryButton:setOn(false)
end

-- hooked events
function onInventoryChange(player, slot, item, oldItem)
      local player = g_game.getLocalPlayer()
      if(player) then 
      local vocation = player:getVocation()
      if(vocation ~= 0) then
      inventoryWindow:setImageSource(Backgrounds[vocation].path)
      end
      end
      
  if slot >= InventorySlotPurse then return end
  local itemWidget = inventoryPanel:getChildById('slot' .. slot)
  if item then
    itemWidget:setStyle('Item')
    itemWidget:setItem(item)
  else
    itemWidget:setStyle(InventorySlotStyles[slot])
    itemWidget:setItem(nil)
  end
end

tentei usar esse e ñ foi

function onExtendedOpcode(cid, opcode, buffer)
if opcode == 25 then
    doSendPlayerExtendedOpcode(cid, 26, getPlayerVocation(cid))
end
    return true
end

quero so a oque precisar no servidor, pois ja tentei varios cods e n vai ;x
