Question

I only found this related to what I am looking for: Split string by count of characters but it is not useful for what I mean.

I have a string variable, which is an ammount of 3 numbers (can be from 000 to 999). I need to separate each of the numbers (characters) and get them into a table.

I am programming for a game mod which uses lua, and it has some extra functions. If you could help me to make it using: http://wiki.multitheftauto.com/wiki/Split would be amazing, but any other way is ok too.

Thanks in advance

Answer 1

Corrected to what the OP wanted to ask:

To just split a 3-digit number in 3 numbers, that’s even easier:

s='429'
c1,c2,c3=s:match('(%d)(%d)(%d)')
t={tonumber(c1),tonumber(c2),tonumber(c3)}

The answer to “How do I split a long string composed of 3 digit numbers”:

This is trivial. You might take a look at the gmatch function in the reference manual:

s="123456789"
res={}
for num in s:gmatch('%d%d%d') do
    res[#res+1]=tonumber(num)
end

or if you don’t like looping:

res={}
s:gsub('%d%d%d',function(n)res[#res+1]=tonumber(n)end)
