How and When to Use the Chatted Event in Admin Scripts?

Using the chatted event:

The Chatted event is an event of PlayerObjects. When they fire, it simply returns two parameters; Message (string) and Recipient (player/userdata).

Message is what the player said, and Recipient is who they sent it to (if they whispered the message), otherwise it's nil.

local p = game.Players.LocalPlayer -- needs to be a localscript for this line to not be nil

p.Chatted:connect(function(message,rec)
    print("Player sent " ..message.. "to" ..tostring(rec))
end)

-- you can also do:

function chat(message,rec)
    print("Player sent " ..message.. "to" ..tostring(rec)) -- using tostring() stops the code from breaking if the player doesn't whisper their message, it would simply print "Player sent Hello! to", with no player.
end

p.Chatted:connect(chat)

This code would print, for example: "Player sent Hello! to Firplius".

Hope I helped!
