I’m currently trying to make a message system in Roblox, so that the server can send a message like so:

local displayMessageEvent = Instance.new("RemoteEvent")
displayMessageEvent.Name = "DisplayMessageEvent"
displayMessageEvent.Parent = ReplicatedStorage

displayMessageEvent:FireAllClients("Hello, World!")

and the client can accept it like so:

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Players = game:GetService("Players")

local displayMessageEvent = ReplicatedStorage:WaitForChild("DisplayMessageEvent")

local function onDisplayMessage(message)
    local player = Players.LocalPlayer
    local playerGui = player:WaitForChild("PlayerGui")
    local screenGui = playerGui:WaitForChild("ScreenGui")
    local textLabel = screenGui:WaitForChild("TextLabel")

    textLabel.Text = message
end

displayMessageEvent.OnClientEvent:Connect(onDisplayMessage())

I would like to pass arguments into the onDisplayMessage() from the displayMessageEvent, yet I’m not sure how I would get it.

I tried doing something like:

displayMessageEvent.OnClientEvent:Connect(onDisplayMessage(displayMessageEvent.event))

but it just isn’t working.
