Set Username

[MTRNord]

Hi is there an way to change the Username of the person who ran an command? Like an auto nick? (I only search the function to set the Username. The Rest am I working on)

You may be able to change the username property on the player by running player.username = "name";

[MTRNord]

ok I will try that :)

"Username of the person who ran an command" I'm not sure what you mean by that. When should the username be changed ?

[MTRNord]

Imagine someone types "/nick" in the Chat. My plugin should be triggerd and the name/nick of this Person should change for others. So I need a was to change the property username of the person who ran the command "/nick"

Ok here is how you can add such a command #126 (comment)
It is not possible (because of the minecraft protocol) to change the username.
However you can change the displayName. To do that you need to send the player_info packet http://prismarinejs.github.io/minecraft-data/?d=protocol#toClient_player_info to everybody with action set to 3 and with the display name you want.

 serv._writeAll('player_info',{
      action: 3,
      data: [{
        UUID: player._client.uuid,
        displayName: "new_display_name"
      }]
    });

Yeah I think that is what I searched for :) thanks

Also: wouldn't it be better if the chat lib uses instead of the Username the displayName or do I mix something up there?

here is an example to create a command https://github.com/PrismarineJS/flying-squid/blob/master/doc/API.md#playercommands

What do you mean by chat lib ?

I'm not sure where the display name should be used, but yeah maybe we should use it at some places. Do tell if you find places where the display name make more sense than the username ;)

[MTRNord]

I mean the Name that is showed before an chat message :) There could maybe the DisplayName make sense.

[rom1504]

Does the vanilla server do it ?
How is the display name set in the vanilla client (/with a vanilla server) ?

[MTRNord]

From Bukkit (Spigot Code GIT): https://hub.spigotmc.org/stash/projects/SPIGOT/repos/bukkit/browse/src/main/java/org/bukkit/entity/Player.java#44 (I reference Bukkit because Bukkit also does have Nick plugins and the vanilla one doesn't)

There says the inline Documentation (at least i understand it in that way), that the Display Name is used in the Chat.

Ah. I see. So the actual username of the player is retained, but the display name is changed. 👍 this should be fixed as to not cause future player data saving errors based off of username when people change the username instead of display name.
