RoundHaven

Create a temporary event world, run a last-player-standing round, then send every participant back to their normal server state.

RoundHaven is a Paper plugin for SMPs, communities, and creator events. It creates its own event world, backs up participating players before the round, and restores them when the event ends.

Features

• Creates dedicated temporary event worlds without modifying your normal worlds
• Includes three arena templates: flat, box, and islands
• Saves inventory, armour, offhand, location, game mode, XP, health, hunger, effects, and flight state
• Restores saved player data after an interrupted event when the player rejoins
• Supports 2–16 players, countdowns, eliminations, winner announcements, boss bars, and action bars
• Can reset an arena automatically after each round
• No dependencies

Quick start

/roundhaven create saturday-box box
/roundhaven join saturday-box
/roundhaven start saturday-box

The last player standing wins.
