Name Changer

A mod for changing the player’s name. Designed to replace the player’s name consistently across the game.

Useful for roleplay servers, content creation, screenshots, or simply using a different display name without changing your account username.

Needs to be installed both on the client and the server to work fully.

Features

The primary feature of this mod is obviously changing the player's name. Here’s every place this affects:

UI & Display

• Chat name labels
• Nameplates above players
• Player list (under Tab)
• Social interactions screen
• Scoreboard sidebar display
• MOTD for LAN worlds

Commands & System Integration

• Entity selection in commands
  • Works with both suggestions and execution
  • Original names still work
• Various system messages
  • Death
  • Advancements
  • Join/Leave

On top of that there's the /name command for changing the name, which requires operator permissions. It has two subcommands:

• /name set <target> <name> sets the name of the target player
• /name reset [<target>] resets the name of the target player (or self if target is omitted) to what it was originally

Custom names are stored per-world and persist between reloads.

Names

The custom name inputted in the /name set command is a text component. You can read more about them on the Text Component page on the Minecraft Wiki.

Here's examples of using the /name set command:

Plain text:

/name set @s mineTomek

Plain text with spaces or other special characters:

/name set @s "mineTomek :3"

Formatted text:

/name set @s {text: "mineTomek", color: "#6dc53b", bold: true}

Formatting only affects chat messages and the player list.
In most other places, Minecraft strips formatting and displays plain text instead.
