Typing effect (ROBLOX)

write = function(str, delay, times, output)
    --print("Output's a "..tostring(type(output)))
    local s1 = string.rep(str,times) --makes the "times" work
    local s2 = "";
    for i=1,#s1 do --for every letter in s1
        s2 = s2..s1:sub(i,i);
        if not string.find(s2:sub(i,i),"%s") then
            wait(delay); --makes it so it doesn't delay on whitespace characters
        end
        if type(output) == "userdata" then --sadly, if it's directly a string it won't work
            local cn = output.ClassName; --saves a lot of typing
            if output:IsA"GuiObject" and cn~="Frame" and cn~="ScrollingFrame" then
                output["Text"] = s2;
            end
        elseif type(output) == "function" then
            output(s2);
        end
        i=i+1; --proceeds to the next letter
    end
end

--Example

write("Typing effect, woohoo!", 0.05, 1, print)
--The first arg. is the text, "0.05" is the delay between letters, "1" is how much times it's going to be written, "print" means it's going to be printed (You can set it so it sets a name of something, text from GuiObjects etc.)
