Relay Speedrun
by OH__minus
Relay Speedrun lets a group of players trade control of one shared speedrunner on a Fabric server, with each turn handing over the character's state.
What it does
Relay Speedrun is a server-side minigame for multiplayer relay runs. A group of players hands a single virtual character back and forth: whoever holds the current slot drives it for a set period, then the next player picks it up with the health, hunger and inventory already in place. Turns follow the order in which people joined the server and loop back to the first player once everyone has gone.
Players waiting for their slot watch from spectator mode, where they can follow the run's progress but cannot move, look around the world or follow the active player. On-screen messages keep everyone informed: the action bar shows the time left in the current turn, the title and subtitle show whose turn it is and how long remains, and the sidebar gives spectators the real-time attack and in-game time of the run. A set of commands starts, pauses, resumes and stops a relay, and sets or queries the turn time limit and countdown.
Key features
Shared speedrunner
One virtual player entity is controlled by a different player in turn, so the whole group works on a single run.
Turn handover
At the end of a turn, the next player takes over with the speedrunner's health, hunger and inventory intact.
Turn order
Turns follow the order in which players joined the server and repeat in a cycle.
Spectator information
Waiting players see the time until their turn and the progress of the run, but cannot move or inspect the world.
Relay commands
Commands start, pause, resume and stop a relay, and set or query the turn time limit and countdown.

How it compares
Random Item Speedrun is a Fabric mod for 1.21.8 that works on either side, and neither needs it, under the MIT License, and it is not open source. Linked Deaths is a Fabric mod for 1.21.1 that needs both client and server, also under the MIT License. Relay Speedrun runs on the server alone, so players join without installing anything, and it targets 1.21.11 only.
