If the item is added in the map on certain places and shouldn't be removed, you can add an uniqueid to it, then set the storage to that uniqueid.

local storage = item.uid

If the item is something people get with a quest for example, you can set the same storage number but every item 1 extra value and remove the item after using.

Yes, i try do that but i found one problem..Each item i will need add different storage and i need only 1 storage to all item each item you use you gain +1 storage..

You can do both, storage with item.uid to check if someone already used the item, then add different storage with +1 value, so if you used all items, the value of that second storage will be 7 (or 8 if you set it to 0).

Like that?

local table = {
[] = {storage = 1}
}
for k,v in pairs do
if item.uid == k then
if getPlayerStorageValue(cid,77878) <= 8 then
setPlayerStorageValue(cid, v.storage, getPlayerStorageValue(cid,v.storage) + 1)
doSendMagicEffect(toPosition,31)
end
end
end

You don't need to use a table or anything, you can just check for the item.uid as storage to see if someone already used the item.

if(getPlayerStorageValue(cid, item.uid) > 0) then
	doPlayerSendTextMessage(cid, MESSAGE_INFO_DESCR, "You already used this item.")
	return true
end

Then under it add what it should do and set the storages.

setPlayerStorageValue(cid, item.uid, 1)
setPlayerStorageValue(cid, 9566, getPlayerStorageValue(cid, 9566) + 1)

Limos, other doubt to restore this storage to -1 , i can use isinarray? ou setPlayerStorageValue(cid,item.uid , -1) in the npc?

 

[Limos]

If you want an npc to check if someone used all items, you only have to use the second storage.

if(getPlayerStorageValue(cid, 9566) >= 7) then

 

[hasbro]

No, i need back all storage of item.uid to -1 ? How i can do that?

 

[Limos]

You can do it like this, use the uniqueids of the items in the storages table.

local storages = {10922, 10923, 10924}
for _, storage in pairs(storages) do
	setPlayerStorageValue(cid, storage, -1)
end
