[Cosmotonio]

someone make a function that check the string?

Can you be more specific plz?

There is already this function in TFS global.lua.

function isNumber(p)
	local m = ""
	for i = 1, string.len(p) do
		m = string.sub(p, i, i)
		if m == "0" or m == "1" or m == "2" or m == "3" or m == "4" or m == "5" or m == "6" or m == "7" or m == "8" or m == "9" then
			-- continue
		else
			return FALSE
		end
	end
	return TRUE
end

how i can change a number to a int number?

ROFL @ TFS scripters!

function isNumber(str) 
    return tonumber(str) and TRUE or FALSE
end

Or:

function isNumber(str, bool)
	if bool == true then
		return type(str) == "number" and TRUE or FALSE
	end
	return tonumber(str) and TRUE or FALSE
end

If you use bool that's true value, then it must be the type number not string so it cannot be
str = "23423"
but:
str = 23423

Try that one


With your function these would give bugs:
isNumber(function() end)
isNumber(nil)
isNumber({})

It will give you an error message, but not on mine
