Help with string.sub

[SSJMateusz]

I am currently trying to make this NPC talk system, where the letters appear 1 by 1, for this I am using
string.sub.
But I have run into an issue with it, right now I am printing “Hello world” letter by letter in the output but when it comes to space, it cant print it because it is nil, how would I go around this?

Thanks in advance

Are you talking about a literal space character? A space is still a space, not nil. Could you show your code?

Oops, i’ve looked back at my code and i made a mistake with my loops, its working now so ill just mark your comment as solution

the problem was i did 2 for i loops and used the wrong i variable if that makes sense

string.sub()

it is a function that can create a smaller string of the inputted string that starts at I and ends at J.

for a typewriter effect, this is an example:

for i = 1, string.len(text here), 1 do
      textObject.Text = string.sub(text, 1, i)
      task.wait()
end

this is not an efficient approach, as it does not support RichText or auto translations.
