MCMultiplayer
by Denis72623
MCMultiplayer lets players open a world to other players from the pause menu by creating a WAN server with one click.
What it does
Creating a WAN server takes one click in the ESC pause menu, using UPnP port mapping to open the port on the router. The mod also detects the local and global IP addresses of the host and lets them be copied to the clipboard with a hotkey, so the address can be shared with friends straight away. Local LAN and global IPv4 and IPv6 addresses are all shown, and the mod can stream screenshots of them.
The host also gets built-in server controls for banning and pardoning players by username or IP address. The mod is for players who want to play with friends in a world they already have, and for hosts who want to manage who joins without leaving the game. It is built for Forge only, with files for 1.20.1, and it can be installed on a client or a server, while neither needs it. The code is open source under the MIT License, and the source is public.
