SilentJoin - Minecraft Paper Plugin

A Minecraft Paper plugin for Paper 1.21.11 that hides join and quit messages for operators and configured players.

Features

• Hide messages for operators: Join/quit messages are automatically hidden for server operators
• Configurable silent join: Operators can toggle silent join for any player using /silentjoin <player>
• Persistent configuration: Silent join settings are saved to a JSON file and persist across server restarts
• UUID-based storage: Uses UUIDs instead of player names for reliable player identification
• Offline player support: Works with both online and offline players

Commands

/silentjoin <player>

Toggle silent join for a player. When enabled, the player's join and quit messages are hidden.

Permission: silentjoin.command (default: op)

Usage Examples:

• /silentjoin PlayerName - Toggles silent join for PlayerName
• /silentjoin 12345678-1234-1234-1234-123456789012 - Works with both player names and UUIDs

Messages:

• If enabled: "Silent join enabled for <player>."
• If disabled: "Silent join disabled for <player>."
• If no player provided: "Usage: /silentjoin <player>"

Configuration

The plugin stores silent join settings in plugins/SilentJoin/silentjoin.json. The file contains a list of UUIDs for players with silent join enabled.

Example silentjoin.json:

[
  "12345678-1234-1234-1234-123456789012",
  "87654321-4321-4321-4321-210987654321"
]

Behavior

Join/Quit Message Hiding

Messages are hidden when:

1. The player has operator status (isOp())
2. OR the player's UUID is in the silent join configuration list

Command Behavior

The /silentjoin command allows operators to:

• Enable/disable silent join for any player (online or offline)
• Changes are saved immediately to the configuration file
• Reloading the server maintains these settings

Permissions

• silentjoin.command - Allows usage of the /silentjoin command (default: op)
