Hi guys! I managed to save a file like this:
settings.txt

0 0 1 45 11 16000 5

These are several settings that the script will use when server starts.
I need you to tell me how to use the split function to load all this stuff like:
if(file exists) then
     var1 = 1st part of splitted line -0-
     var2 = 2nd part of splitted line -0-
     var3 = 3rd part of splitted line -1-
     var4 = 4th part of splitted line -45-
end

and so on.

Read the whole line and pass it to string.gmatch()

1
2

local t = {}
for w in string.gmatch(yourline, "%w+") do
	table.insert(t,w)
end
--Then use sth like
parse("setmoney "..id.." "..t[6])

This doesn't work, there's an error that makes each variable in the file nil!

Any other suggestions using the split function?

You can use the toTable function, it's very easy.

function toTable(t,m)
	if not m then m = "%s"
	local tbl = {}
	m = "[^"..m.."]+"
	for w in string.gmatch(t,m) do
		table.insert(tbl,w)
	end
	return tbl
end

Now use it like this:

1

for lines in io.lines("settings.txt") do
	local line = toTable(lines)
	var1 = tonumber(line[1])
	var2 = tonumber(line[2])
	...
end

I am making a very good script and this is the only error I get in theese 2.000 lines of code!

That really worked, thanks!
