A function to check storage if is string or not...

[kito2]

Hi there, well if someone can make this: I need a function that check player storage if it is a string or number...
The idea of the function is to be used and see if the storage value is a string, then it will be changed for a number.

local function checkStorage(pid, storage)
   return setPlayerStorageValue(pid, storage, tonumber(getPlayerStorageValue(pid, storage)))
end

That won't check since it's set~ and you can't use tonumber in a string, tonumber is to check if parameter is a number, not to convert it to one (unless it is a number).

I thought tonumber converted a numeric string into a number (although I guess with the way lua handles typing it doesn't matter).

K try this..

local function checkStorage(pid, storage)
   local storageInNumFormat = tonumber(getPlayerStorageValue(pid, storage))

   if (storageInNumFormat ~= nil) then
      setPlayerStorageValue(pid, storage, storageInNumFormat)
   else
      setPlayerStorageValue(pid, storage, -1) -- if it's a string it will be changed to -1
   end

   return true
end

if tonumber(a) ~= nil then
   --it's a number
end

?

? If you're asking if that's the correct use, then yes you could check that way.
This is an example, so you can notice:

a = {1, "1", "a"}
for i = 1, 3 do
    if tonumber(a[i]) then
       print(" " .. i .. " ")
    else
        print("fail")
    end
end

Will return

 1 
 2 
fail

Which means, 1 is number, "1" is number (you can only convert strings that contain numbers), "a" fails.

Kk, that's what I thought after reviewing what I posted, thanks a bunch for the wisdom!
