Custom Chat Gui not working?

Custom chat is with filtering is easy to do.

Have a remote event in workspace and name it PlayerChatted. Insert a script inside it and put this code into it:

script.Parent.OnServerEvent:connect(function(plr,msg)
script.Parent:FireAllClients(plr,msg)
end)

Now you need to make a local script inside your chat gui and do a code like this:

-- Client Sided
local mouse = player:GetMouse()

TextBox.FocusLost:connect(function(enterPressed)
if enterPressed == true then
game.Workspace.PlayerChatted:FireServer(TextBox.Text)
end
end)

mouse.KeyDown:connect(function(key)
if key == "/" then
TextBox:CaptureFocus()
end
end)

game.Workspace.PlayerChatted.OnClientEvent:connect(function(plr,msg)
--add your gui chat stuff in here
print(plr.." has said "..msg)
end)

Hopefully looking at this would let you see what you're doing wrong or how to make your system better. Obviously I didn't include all the gui stuff or fancy features, as you'll be able to do them on your own. If this still doesn't work, or you have future questions about filtering enabled, please ask me.

PS: I wrote this code on the website so I didn't test it, but those are the fundamentals needed to create the system. Hopefully you can work it out from there.

Hai.I am using a method someone thought me but i still hope it helps

i assume the guis is created.

Now heres the code

ServerScriptService

local event = game:GetService('ReplicatedStorage'):WaitForChild('Chatted')

event.OnServerEvent:connect(function(player, nameColor, message, messageColor)
    event:FireAllClients(player, nameColor, message, messageColor)
end)

ReplicatedStorage

Insert a RemoteEvent in RS

StarterGui

I assume the guis is created So now,Insert a local script into the guis

Put this code,Its long

game.StarterGui:SetCoreGuiEnabled(Enum.CoreGuiType.Chat, false)

local colors = {'Deep orange', 'Toothpaste', 'Lime green', 'Hot pink', 'Cyan'}--Change to your colors

math.randomseed(os.time())
math.random()
math.random()
math.random()
math.random()

local player = game.Players.LocalPlayer
local nameColor = BrickColor.new(colors[math.random(1, #colors)]).Color
local messageColor = BrickColor.new('Institutional white').Color
local messageBox = script.Parent:WaitForChild('name of frame'):FindFirstChild('Name of text box')
local UIS = game:GetService('UserInputService')
local event = game:GetService('ReplicatedStorage'):WaitForChild('Chatted')


if player.Name == 'Jeysea' then
    nameColor = BrickColor.new('Really red').Color
end

function onInput(Input, GPE)
    if GPE then return end
    if Input.KeyCode == Enum.KeyCode.Slash then
        messageBox:CaptureFocus()
    end
end

function onFocus()
    if messageBox.Text == 'Press \'/\' to type a message...' then
        messageBox.Text = ''
    end
end

function onFocusLost(EnterPressed)
    if EnterPressed then
        if messageBox.Text ~= '' then
            event:FireServer(nameColor, messageBox.Text, messageColor)
            messageBox.Text = 'Press \'/\' to type a message...'
        else
            messageBox.Text = 'Press \'/\' to type a message...'
        end
    else
        if messageBox.Text == '' then
            messageBox.Text = 'Press \'/\' to type a message...'
        end
    end
end


--player.Chatted:connect(function(message)

UIS.InputBegan:connect(onInput)
event.OnClientEvent:connect(onEvent)
messageBox.Focused:connect(onFocus)
messageBox.FocusLost:connect(onFocusLost)

I hope this helped,if anything happens or goes wrong,Comment down.
