BetterLANBroadcaster

A Spigot plugin that broadcasts Minecraft servers over LAN using UDP multicast, allowing clients to discover servers without manually entering addresses.

Features

• Follows the Minecraft LAN discovery protocol, sending server information to 224.0.2.60:4445
• MOTD supports {online} (current online players) and {max} (max players) variables, automatically replaced in real-time
• Dynamic start/stop broadcasting via commands
• Online modification of broadcast MOTD and broadcast delay
• View current broadcast status
• Custom broadcast port (manual or auto-detect)
• Debug mode for real-time broadcast packet logs
• Multi-language support (English, Chinese)
• Hot-reload all configurations

Commands

Tip: /betterlanbroadcaster is the full command, /blb is its alias; both are equivalent.

All commands require the betterlanbroadcaster.admin permission, available to OPs by default.

Configuration

plugins/BetterLANBroadcaster/config.yml

# Language setting: en or zh
language: en

# Server MOTD displayed on LAN
# Available variables:
#   {online} - Current online player count
#   {max}    - Maximum player count
motd: "A Minecraft Server"

# Broadcast delay (milliseconds)
# Default: 1500 ms = 1.5 seconds
broadcast-delay-ms: 1500

# Debug mode: when true, each broadcast packet is logged to console
debug: false

# Broadcast port: set to 0 to auto-detect server port, or specify a port number
broadcast-port: 0

Multi-language

Language files are located in the plugins/BetterLANBroadcaster/lang/ directory:

• messages_en.yml - English language file
• messages_zh.yml - Chinese language file

Set language to en or zh in config.yml to switch languages.

Color Codes

MOTD supports Minecraft color codes using the & symbol followed by a color character to color the server name.

Common color codes:

Format codes:

For example, setting a colored MOTD in the config:

motd: "&6&l✦ &eBetterLAN &7- &aSurvival Server &6&l✦"

In-game, it will display as gold ✦ BetterLAN - Survival Server ✦.
