Tested Minecraft Versions:
1.161.17
If a player is in a world named "world" (so in the overworld) and writes something in the chat, the message looks like this:
[OVERWORLD]<PlayerName> <Message>
If the world he is in is called "world_nether", i.e. he is in the Nether, the message looks like this:
[NETHER]<PlayerName> <Message>
And if the world is called "world_the_end" (it is in the end), the message looks like this:
[END]<PlayerName> <Message>
I hope you can do something with the plugin, if you have any problems write me on Discord: Champion#0230
