This is not what i meant, what i meant is:

how do i make the typewriter automatically take out strings from the table and do a typewriter effect on those strings. i am asking to do something like this

local table = {"blah ok", "yeaheayh" , "third word"}
  [insert typewriter here that automatically takes out strings from the table and does the effect here]

the tutorial video you’ve shown me doesnt use tables.

Are you trying to perform a typewriter effect on each string as an individual, or the entire table?

i am trying to perform a typewriter effect on each string from the table (so it changes automatically to the next string once it finished using a typewriter effect on the first string of the table)

In the past I’ve used an iterator for this:

local typewrite do
	
	local function iter(s, i)
		if i < s:len() then
			i = i + 1
			return i, s:sub(1, i)
		end
	end
	
	function typewrite(s)
		return iter, s, 0
	end

end

You would use it like so:

for _, text in typewrite("my string") do
	print(text)
end

For your specific use-case, here’s what I would do:

local messages = {"foo", "bar", "blah"}

for _, s in ipairs(messages) do
	for _, text in typewrite(s) do
		someLabel.Text = text
		-- wait for some amount of time
	end
end

You could iterate through the string instead and concatenate the text with the next character,

local goal = "string"
local obj = something.TextLabel

obj.Text = "" -- or just keep it empty initially
for char in goal:gmatch(".") do
    obj.Text = obj.Text .. char
    wait()
end
