RevScripts unique usage

[Tibia Demon]

i try use this by @Dakos but i get error. i need make 1 forth function too for remove the custom attribute using other item gem or key and make it normal item for all player
and i try add item description for say item found by playername or belong playername.

TFS 1.X+ - Item what can be used only by player what get it.

Its possible? Im thinking about exp items, what can be got from x npc for something, but i want add "permission" to use it only for player what collected it (tfs 1.5 8.6)

thank you! all 4 function work
this is my onlook

local ec = EventCallback

ec.onLook = function(self, thing, position, distance, description)
    local description = "You see " .. thing:getDescription(distance)
    if self:getGroup():getAccess() then
        if thing:isItem() then
            description = string.format("%s\nItem ID: %d", description, thing:getId())

            local actionId = thing:getActionId()
            if actionId ~= 0 then
                description = string.format("%s, Action ID: %d", description, actionId)
            end

            local uniqueId = thing:getAttribute(ITEM_ATTRIBUTE_UNIQUEID)
            if uniqueId > 0 and uniqueId < 65536 then
                description = string.format("%s, Unique ID: %d", description, uniqueId)
            end

            local itemType = thing:getType()

            local transformEquipId = itemType:getTransformEquipId()
            local transformDeEquipId = itemType:getTransformDeEquipId()
            if transformEquipId ~= 0 then
                description = string.format("%s\nTransforms to: %d (onEquip)", description, transformEquipId)
            elseif transformDeEquipId ~= 0 then
                description = string.format("%s\nTransforms to: %d (onDeEquip)", description, transformDeEquipId)
            end

            local decayId = itemType:getDecayId()
            if decayId ~= -1 then
                description = string.format("%s\nDecays to: %d", description, decayId)
            end
        elseif thing:isCreature() then
            local str = "%s\nHealth: %d / %d"
            if thing:isPlayer() and thing:getMaxMana() > 0 then
                str = string.format("%s, Mana: %d / %d", str, thing:getMana(), thing:getMaxMana())
            end
            description = string.format(str, description, thing:getHealth(), thing:getMaxHealth()) .. "."
        end

        local position = thing:getPosition()
        description = string.format(
            "%s\nPosition: %d, %d, %d",
            description, position.x, position.y, position.z
        )

        if thing:isCreature() then
            if thing:isPlayer() then
                description = string.format("%s\nIP: %s.", description, Game.convertIpToString(thing:getIp()))
            end
        end
    end
    return description
end

ec:register()

fixed
