Minetest 0.4.16+ mod: chat2
|
||
|
|
chat2 is mod for Minetest, created by Andrey. It's purpose is to improve or replace game built-in chat:
|
||
|
|
|
||
|
|
+ Higlight some messages in different colors - nearby talk, PM messages, messages with your name in it, shouts(!)
|
||
|
|
+ Also can show all regular chat messages (use "/chat2 *" command)
|
||
|
|
+ Switch on/off (use "/chat2" command)
|
||
|
|
+ Old messages dissapear after some time
|
||
|
|
- Problems with unicode symbols on some clients
|
||
|
|
|
||
|
|
This mod is Free and Open Source Software, released under the GNU LGPLv2.1 or later.
|
||
|
|
I used this mod:https://github.com/vegasd/minetest-mods/blob/master/kmchat/init.lua as example for how to use hud api.
