Hot-Join
by Jab125
With Hot-Join, a second or third player can join a running Minecraft splitscreen session from a fresh instance without restarting the game.
What it does
Hot-Join is a Fabric mod for splitscreen play. It launches new game instances on request and resizes the windows so every active player keeps a usable view. Players who join late do not need to close and reopen the session to start playing alongside the others.
The mod needs Concentration and Fabric API to run. Players add it to their own game, and a server needs no copy. The latest Fabric file is 0.4.0 for 1.21.1, published on 2024-10-22, and the first release came out on 2024-10-06. The code is open source under the GNU Lesser General Public License v2.1 only, and the source code and issue tracker are public.
Splitscreen setups that use a controller are covered as well, since the mod pairs with an input controller mod for assigning devices to each window.
Key features
Automatic instance launch
A new game instance opens when a player asks to join, so no separate launcher step is needed for each window.
Window resizing
The windows are resized automatically as players join or leave, so the layout stays even across the screen.
Following player
One player can follow another during the session, which keeps the group together in one area of the world.
Controller support
Each new window can be assigned its own controller through a companion input mod.

Use cases
Couch co-op on one machine
Friends sharing a single computer can add players in the middle of a session instead of planning every seat before launch.
Late arrivals
A player who sits down after the world is already running can join without restarting the game for everyone else.
Who it’s for: Players who run Minecraft splitscreen on one computer and want to add players during a session. Server owners do not need to install anything for it.

What the author says
Hot-Join is a splitscreen mod that works by launching new instances and automatically resizing windows. Click the Pause button on a connected controller that is not the current active controller. This will setup the controller automatically when the second instance launches.
