Hi, what’s not working?

[steep grove]

oh my days i did not respond for so long

so sorry

but uhh basically, i wanna make it so that someones name changes into John Doe or Roblox depending on their Humanoid.DisplayName

but it only appears to one client but not all players

[broken radish]

Hmm... you're a scripter... can you smell it? let me give you a hint... localscript?

Anyways if it happens to one client not all, it seems like the script needs to be a serverscript not localscript. If you don't know what this means, this means you need to use remoteevents to pass along the name to change to the server script, where the server will interpret that and change the text on all clients.

uhh brother, it cant be serverscript

if it can be, i wouldnt be here whining about my issue

TextService.OnIncomingMessage only works on client

also secondly, this worked in a 2 player simulation, but not in a real game

Hmm I see mate, but TextChatService.OnServerReceivingMessage isn't client-only

Here is the code

local TextChatService = game:GetService("TextChatService")

TextChatService.OnServerReceivingMessage = function(textChatMessage)
    local speaker = textChatMessage.TextSource
    if not speaker then return end

    local player = game.Players:GetPlayerByUserId(speaker.UserId)
    if not player then return end

    if player.DisplayName == "John Doe" or player.DisplayName == "Roblox" then
        local prefix = player.DisplayName ... "" --I don't know the symbol so just put it in the string
        local newText = prefix .. textChatMessage.Text

        -- Return message as table
        return {
            Text = newText,
            Metadata = textChatMessage.Metadata,
            TextChannel = textChatMessage.TextChannel,
            PrefixText = textChatMessage.PrefixText,
            ShouldDeliver = true
        }
    end
end

what the heck?

[steep grove]

oh shoot thats a thing?

that is not a thing

[broken radish]

…? https://create.roblox.com/docs/reference/engine/enums/ChatCallbackType#OnServerReceivingMessage

Notice it is NOT an event so you don’t use :Connect(function())

[steep grove]

i did that exact thing

nothing

infact in sent an error that OnServerRecievingMessage doesnt exist
