Get rid of newline using scripts

#1

I am making a custom chat system. But people can click enter before posting in chat and it creates a new line for some reason. How can I fix this? (I want to get rid of a new line when people send a message in my game.)

I know there are other posts, but none of them work for me, or I just don’t understand them. Here is a picture:

Roblox has a disallowed whitespace thing in their regular chat system to prevent things like this, check it out?

#3

Simply make the chatting textbox’s MultiLine property unchecked.

#4

It is unchecked, even textwrapped is unchecked.

I FOUND THE ANSWER!
To anyone who had the problem like me:

Text = string.gsub(Text, "%s+", "")

That will remove all of the whitespaces (newlines and stuff) in the message.

Can’t you just use something like

if string ~= "" then

or

local args = string.split(msg, " ")
local isntspam = false

for i,v in pairs(args) do
    if v ~= "" then
        isntspam = true
    end
end

Text:match("%s+", "")

Remember that string values are objects so you can call the string library functions on them as instance methods with the colon operator (personal preference).

For a more exact match you should make use of anchors which anchor the search pattern to the start/end of a string, those are “^” and “$”. Finally, replace the + modifier (1 or more occurrences) with the * modifier (0 or more occurrences).

Text:match("^%s*$", "")

This way a match only occurs if the subject string matches a search pattern which starts at the beginning of a string and is then followed by 0 or more occurrences of any whitespace character (as indicated by the %s character class) and then ends at the end of a string.
