How could I create or get started with making the chatbox local?

[MoxnyStar (Mox)]

I am trying to make it so that the chatbox can only show messages from people in a specific radius, for example, 100 studs. For the player, they wont see the chat of someone who is over 100 studs away. I am not talking about bubble chat, though. Just the normal chatbox on the top left.

I have tried searching for nearly an hour now on how I can do this, but haven’t been able to find a single thing related except for bubble chat. I would appreciate it if someone can help, or point me to a post that has already done this that I just haven’t found.

To do this, you can take advantage of the fact that TextChatService will ignore TextChatMessages with empty Text properties:

local LocalPlayer = game:GetService("Players").LocalPlayer
local LocalCam = workspace.CurrentCamera

local MAX_HEARING_DISTANCE = 50

function shouldIgnoreMessage(textMsg)
	local messageSrc = textMsg.TextSource
	local sourcePlayer = messageSrc and game:GetService("Players"):GetPlayerByUserId(messageSrc.UserId)

	local sourcePlrChar = sourcePlayer and sourcePlayer.Character

	if not sourcePlrChar then
		return false
	end

	local localPosition = LocalPlayer.Character and LocalPlayer.Character:GetPivot().p or LocalCam.CFrame.p

	local distance = (sourcePlrChar:GetPivot().p - localPosition).Magnitude

	if distance > MAX_HEARING_DISTANCE then
		return true
	end
	
	return false
end

game:GetService("TextChatService").OnIncomingMessage = function(textMsg: TextChatMessage)
	if shouldIgnoreMessage(textMsg) then
		textMsg.Text = ""
		return
	end
	
	-- rest of your OnIncomingMessageLogic...
end

If the user who sent the message’s character is beyond MAX_HEARING_DISTANCE, the message will simply not be seen by them.

This also hides the bubble chat.
