So I’ve been working on a dialog system in which i’m trying to identify the newest character to be added via a typewriter effect. And I’ve been wondering how exactly can I find a character inside a string via a number? I’ve been googling a lot about this and I have tried to look for any other string functions that are what i’m looking for. So is this possible and if so how?
You can use string.sub(str, n, m) in a for loop to generate the typewriter effect. Only m is needed to be incremental while n is a constant of 1. Information about string.sub() is found here as well.

As said @Operatik,
You can use
if string.sub(msg,0,6) == "!test" then
-- Do something
end
I just did if 5 characters are equals to !test
