Printing how many letters are in a text box

Help and Feedback Scripting Support
#1

I am doing this as kind of a test for a matchmaking system. I have no clue why its not working all the way. I need it to update every time something new is added to the textbox. it only prints right as i join the game. Any idea?

local TextBox = script.Parent.Type
local Text = TextBox.Text
local Letters = string.len(Text)
print(Letters)

You need to have an event trigger in your code for when the Text property is changed.

local TextBox = script.Parent.Type

TextBox:GetPropertyChangedSignal("Text"):Connect(function() --This looks for when the text property has changed
     local Text = TextBox.Text
     local Letters = string.len(Text)
     print(Letters)
end)

Alright, is this code running in a Local Script? The icon in the explorer window would look this:

This makes sure the code runs on the client, which is needed to get their typing input.

so sorry for wasting your time, when you gave me the example code, I just typed it up (because i like my scripts a certain way) and made it GetPropertyChangedSignal("text") instead of GetPropertyChangedSignal("Text"). so yes, i was actually getting an error

No worries, I’m just browsing DevForum right now. Glad the issue was an easy fix.

so its just multiplying the number I had when I joined, every time i hit a new letter it just multiplies it by 1 (which of course doesnt change the actual number) it even does it when i hit back space

I want it to print another print every time i add a letter/number

The first issue with the multiplication I’m not sure what would be causing that. I’ll work on a solution for the second issue.

EDIT: Below script will only print when a non-space character is added and will only print out the number of non-space characters. This is handled by using string.gsub to replace spaces with empty strings.

local TextBox = script.Parent
local lastStringNoSpaces = ""

TextBox:GetPropertyChangedSignal("Text"):Connect(function() --This looks for when the text property has changed
	local Text = string.gsub(TextBox.Text," ","")
	local Letters = string.len(Text)
	if Text ~= lastStringNoSpaces then
		print(Letters)
		lastStringNoSpaces = Text
	end
end)
