Textbox Ease-Of-Use Question

Help and Feedback Scripting Support
#1

Hello, I am making a Trivia Game, and I want the user to type the correct input inside the Textbox. I want user input to be correct so I have created a script to verify user input. I want the script to ignore if a user accidentally adds a spacebar in front of or behind the text.

Here’s my script for checking the user’s input-

local function Question_Answer(Answer)

	local Input = game.Players.LocalPlayer.PlayerGui.ScreenGui.ScrollingFrame.Screen.Input
	local Submit = game.Players.LocalPlayer.PlayerGui.ScreenGui.ScrollingFrame.Screen.Submit

	Submit.MouseButton1Click:Connect(function()
		local Input_Lower = string.lower(Input.Text)

		if Input_Lower == Answer then
			game.Players.LocalPlayer.PlayerGui.ScreenGui.ScrollingFrame.Screen.Correct.Visible = true

		else
			game.Players.LocalPlayer.PlayerGui.ScreenGui.ScrollingFrame.Screen.Wrong.Visible = true
		end
				
	end)
	
end

Question_Answer('yes')

How do I go about achieving this? :thinking:

#2 
local _string = " Hello world! "
_string = string.gsub(_string, "^%s+", "")
_string = string.gsub(_string, "%s+$", "")
print(_string) --"Hello world!", whitespaces removed.
#3 
local _string = " Hello world! "
_string = string.gsub(_string, "^%s+(.*)%s+$", "%1")
print(_string) --"Hello world!", whitespaces removed.

1 liner.

You could use gmatch to capture the non-whitespace text.

local Message = "\t\tHello\t\nWorld!\t\t" -- \t is tab, \n is newline lol
local Words = {} -- Contains the words
for Word in Message:gmatch("%S+") do -- The `%s` pattern is used to capture text that's whitespace, i.e. tabs, newlines and even spaces. `%S` tells the program to capture anything that is not whitespace and return it.
    Words[1+#Words] = Word -- Adds non-whitespace to the Words array
end
local Answer = table.concat(Words, " ") -- Pieces them together
print(Answer) -- Hello World!
