Custom chat gui isnt filtering text

Help and Feedback Scripting Support

#1

im reworking an old 2010s cell phone model, ive been able to fix majority of it with ChatGPT. my problem is that the gui displays the players recent chat, but is not filtering it. leaving players to say whatever they want.
this is the code for just the gui, im wondering how i can implement the official chat filtering into this?

Tool = script.Parent
local number = ""
local gui,gmain,msgs
local lastphrase = ""

local messageChanged = false

function onEquippedLocal()
	number = ""
	local character = Tool.Parent
	local player = game.Players:GetPlayerFromCharacter(character)
	gui = script.Parent.Cell:clone()
	gui.Parent = player.PlayerGui
	gmain = gui.Main
	msgs = gmain.Messages
	for i,p in pairs(gmain.Buttons:children()) do
		if (p.Name ~= "Call") then
			p.MouseButton1Click:connect(function()
				number = number.. "" ..p.Text
				gmain.Buttons.Call.Text = number
			end)
		else
			p.MouseButton1Click:connect(function()
				for a,b in pairs(game.Players:children()) do
					if (b.UserId == tonumber(number)) then
						Tool.Words.Value = "Player busy"
						messageChanged = true
					end
					if (b.userId == tonumber(number)) and (b.Character:FindFirstChild("Humanoid") ~= nil) then
						Tool.Calling.Value = b.Backpack.CellPhone
						Tool.Words.Value = "Calling " ..b.Name.. "..."
						messageChanged = true
					elseif (b.userId == tonumber(number)) then
						Tool.Words.Value = "Cannot find the player you requested."
						messageChanged = true
					end
				end
				number = ""
				gmain.Buttons.Call.Text = number
			end)
		end
	end
	Tool.Words.Changed:connect(function()
		if (Tool.Words.Value ~= "") and (Tool.Words.Value ~= lastphrase) and messageChanged then
			lastphrase = Tool.Words.Value
			if (msgs:findFirstChild("MSG5") ~= nil) then
				for i = 5, 2, -1 do
					local num1 = i
					local num2 = i - 1
					msgs:findFirstChild("MSG" ..num1).Text = msgs:findFirstChild("MSG" ..num2).Text
				end
				msgs.MSG1.Text = Tool.Words.Value
			else
				msgs.MSG1.Text = Tool.Words.Value
			end
		end
		wait(0.1)
		Tool.Words.Value = ""
	end)
end

function onUnequippedLocal()
	gui.Enabled = false
	script.Disabled = true
end

Tool.Equipped:connect(onEquippedLocal)
Tool.Unequipped:connect(onUnequippedLocal)

You can do this by using the chat service. Below I will leave you a link to a guide made on filtering text which explains it quite well:

Text Filtering | Roblox Creator Documentation

Something just to note, text filtering only works inside of a main game server and does not work in studio.

thanks for the response, ive looked at the documentation for text filtering, but im wondering if i’ll still be able to use it from the way i’m getting the players most recent chat?

Tool.Words.Changed:connect(function()
   	if (Tool.Words.Value ~= "") and (Tool.Words.Value ~= lastphrase) and messageChanged then
   		lastphrase = Tool.Words.Value
   		if (msgs:findFirstChild("MSG5") ~= nil) then
   			for i = 5, 2, -1 do
   				local num1 = i
   				local num2 = i - 1
   				msgs:findFirstChild("MSG" ..num1).Text = msgs:findFirstChild("MSG" ..num2).Text
   			end
   			msgs.MSG1.Text = Tool.Words.Value
   		else
   			msgs.MSG1.Text = Tool.Words.Value
   		end
   	end
   	wait(0.1)
   	Tool.Words.Value = ""
   end)
end
