The chat recorder acts as a proxy between you and your server's chat, listening in to what people say and sending messages on your behalf.
Once you have equipped a chat recorder, you should notice
chat_message events beginning to appear. These will include
the player name, their message and the entity UUID:
while true do local _, player, message, uuid = os.pullEvent("chat_message") if message:find("[Hh]ello") then print(player .. "said hello!") end end
Of course, it’s no good printing to the screen. Let’s say hello back to them! For this, we’ll use the
local chat = peripheral.wrap(--[[ whatever ]]) while true do local _, player, message, uuid = os.pullEvent("chat_message") -- We exclude messages starting with "Hello to you too" so we don't -- reply to ourselves if message:find("[Hh]ello") and not message:find("^Hello to you too") then chat.say("Hello to you too " .. player) end end
One thing to note here is that the chat recorder speaks as the player rather than a separate object. Whilst this does introduce some restrictions, it does grant some interesting abilities.
One of these comes in the form of “captures”. We can specify a Lua pattern which will filter chat. If a message matches the provided pattern, it will not be displayed to other players, instead queuing an event on a computer.
local chat = peripheral.wrap(-- [[whatever ]]) chat.capture("^!") -- Capture any messages starting with "!" while true do local _, message, pattern, player, uuid = os.pullEvent("chat_capture") if pattern == "^!" then -- Run the provided command in the shell. So "!ls" will execute "ls". shell.run(command:sub(2)) end end
In order to use player-specific features inside a manipulator, you will need to bind the chat recorder to yourself. This is done by shift + right-clicking it.
Creative chat recorder
The creative chat recorder functions almost identically to a conventional chat recorder. However it is not tied to any players, operating on the entire server. Consequently:
.saywill not be bound to any player, printing a raw string instead.
.capturewill capture the messages of all players.
It is recommended that you blacklist the
plethora:chat_creative module if you operate a creative server.
The chat recorder can be configured using the
chat category of the
maxLength=100: The maximum length a chat message can be. Set to 0 to allow any length.
allowFormatting=false: Whether Minecraft formatting codes and other special characters can be used.
allowMobs=true: Whether non-player entities can post chat messages.
