Requires the library mod Collective.
This is the server variant of the Beautified Chat mod. It is highly configurable and allows users to change the chat input server-wide. The mod variant you're currently looking at just needs the mod in the server mod list. It will make changes to the chat for all connected players without the need to have it on their clients. There is also a timestamp feature to know when messages were sent.
The client version is also available and is called Beautified Chat [Client].
Both the client and server mod are compatible with each other, server-side takes priority.
In default Minecraft, all chat is in the format:
<Username> Message
The mod by default changes this to:
Timestamp | Username: Message
The default colours can be seen below in the example image. Both the format and the colour codes can be changed with ease via the config. If you don't want the timestamp, just remove it in the chatMessageFormat config option.
The default timestamp format is 24-hours. If you want AM/PM, just input in the timestampFormat config option "hh:mm a" instead of the default "HH:mm".
Configurable: ( how do I configure? )
chatMessageFormat (default = "%timestamp% | %username%: %chatmessage%"): Variables: %timestamp% = timestamp set in timestampFormat. %username% = the username of the player who sent the message.
timestampFormat (default = "HH:mm"): Example time in formats: 5 seconds past 9 o' clock in the evening. *=Default. *(HH:mm) = 21:00, (HH:mm:ss) = 21:00:05, (hh:mm a) = 9:00 PM
The possible colour code values for the next 4 configs are:
0: black, 1: dark_blue, 2: dark_green, 3: dark_aqua, 4: dark_red, 5: dark_purple, 6: gold, 7: gray, 8: dark_gray, 9: blue, 10: green, 11: aqua, 12: red, 13: light_purple, 14: yellow, 15: white.
chatTimestampColour (default = 8, min 0, max 15): The colour of the timestamp in the chat message.Â
chatUsernameColour (default = 2, min 0, max 15): The colour of the username in the chat messsage.
chatMessageColour (default = 15, min 0, max 15): The colour of the chat message.
chatOtherSymbolsColour (default = 7, min 0, max 15): The colour of the other symbols from chatMessageFormat. So everything except the variables.
The default format ("%timestamp% | %username%: %chatmessage%"):
