Chat messages: how do you add text to the chat with names and places in it?

I am creating a game where you stand on different bricks to teleport you to different worlds. when a player touches one of the bricks, i want the chat to say:

could somebody please help me?

Hopefully, you have scripting knowledge so this will be easily understandable:

Creating messages in the Chat requires the script to be in a LocalScript in StarterGui, so I do recommend using a Remote/BindableEvent to do this.

Firstly, When a Player touches the brick, make it fire an event. I will call my event 'Event'. If you are using a localscript when the player touches the brick, change the scripting accordingly.

Touching Brick Script (ServerScript):

local event = game.ReplicatedStorage.Event -- Change this to where your BindableEvent is.

script.Parent.OnTouched:connect(function(plr)
event:Fire(plr, gametheywentto) -- Change 'gametheywentto' to the name of the Game you are teleporting them to
-- Rest of teleporting script
end)

(Sorry for any scripting errors, I'll try to correct them if I find any, doing this off the top of my head)

Then, In a 'PlayerLeavingScript' (LocalScript placed in StarterGui), we need to call a function when the Event is Fired.

In my example I will call it PlayerLeft

For this function, you need two arguments: The Player Who Left and The Game they went to

so it will end up as:

function PlayerLeft(plr, game)
	-- Rest of the code
end

Now for the most important part: To Create text in the chat, use this function:

game.StarterGui:SetCore("ChatMakeSystemMessage", {}) --Information goes into {}

So then, we create it accordingly:

game.StarterGui:SetCore("ChatMakeSystemMessage", {
	Text = ""; -- Change the Text Here
	Color = Color3.new(0, 1, 1); -- Cyan is (0, 255 / 255, 255 / 255). Optional, defaults to white: Color3.new(255 / 255, 255 / 255, 243 / 255)
	Font = Enum.Font.SourceSans; -- Optional, defaults to Enum.Font.SourceSansBold
	FontSize = Enum.FontSize.Size24; -- Optional, defaults to Enum.FontSize.Size18
})

And the function will finish off with:

function PlayerLeft(plr, game)
	game.StarterGui:SetCore("ChatMakeSystemMessage", {
	Text = plr.Name .. " has left the game to play " .. game; 
	-- Add Extras if you wish
})
end

then finally, we connect it with the Event being fired:

local event = game.ReplicatedStorage.Event -- again, change

event.Event:connect(function(...)
	PlayerLeft(...)
end)

And there we go, hopefully I wrote this correctly.

If you want me to rewrite it, just ask.
