1.16 is no longer supported in these forums.

 

In supported versions of minecraft you would do something like:

server.getPlayerList().getPlayerByName(name)

Where the server object can be accessed from Level.getServer() if you don't already have a reference.

The above only works if the player is logged into the game and the world is loaded locally. You cannot for example do that client side in multiplayer.

 

In general, it is a bad idea to use player names in code.

Internally minecraft identifies players using a UUID for each player.

The name is only used for display purposes or commands. It is not any form of unique identifier.

The UUID can also be used when a player is offline.

You can see these UUIDs in the save's  playerdata sub folder.

Thank you so much, I'll try it!But does this method look like it can only be called by the server?

Огромное спасибо, я попробую! Но похоже ли, что этот метод может вызываться только сервером?

So it is, having received information about the player, you can send a packet with the necessary data to the client

https://github.com/andreybadrey/keymodoverlay

something similar is here, this mod was written to test just the possibility of data exchange: Client1 -> server -> client2 -> server -> client1

look it up

for 1.16 you need modify this
