LAN World Plug-n-Play

This mod significantly expands the capabilities of the standard "Open to LAN" function in Minecraft, providing complete control over server settings through a convenient graphical interface.

Main Features

Flexible Authorization System

You now have three options for player authentication:

• Enable - standard verification through Mojang servers, allows only players with official Microsoft accounts to join
• Disable - disables verification, allowing any players to join, including those using offline mode
• Disable + UUID Fixer - intelligent system that matches player names with official UUIDs from the Mojang database, preserving inventories and preventing item loss when switching between modes

Advanced UUID Management

The /uuidfixer command provides complete control over username and UUID mapping:

• /uuidfixer enabled - activates or deactivates the UUID fixer function
• /uuidfixer list - displays all current mapping rules
• /uuidfixer force - adds new rules or updates existing ones
• /uuidfixer remove - removes the specified rule from the list
• /uuidfixer test - checks which rule applies to a specific username

Network Settings

Complete control over network parameters:

• Changing server port
• Automatic port forwarding via UPnP (if supported by the router)
• UPnP management through the graphical interface or /upnp command
• IP address detection (local and public) with copy to clipboard capability
• /ip command for detailed address information

Server Administration

Comprehensive game world management tools:

• Enable/disable PvP
• MOTD configuration (message displayed in server list)
• Operator rights management via /op and /deop commands
• Creating player whitelist with /whitelist command
• Ban system: /ban, /ban-ip, /banlist
• Removing restrictions: /pardon, /pardon-ip

Additional Features

• Automatic saving of settings to configuration file
• Most parameters can be changed after server startup
• Ability to return to the standard open to LAN screen
• Replacing the "Report Player" button in the game menu

Dedicated Server Operation

When installed on a dedicated server, only the UUID fixer function is available, which is activated when the uuid_fixer.json file is present in the server's root folder. The /uuidfixer command is also available on the server side.
