DungeonRefresher

Automatically regenerates loot in chests, barrels, and trial vaults after a configurable cooldown.

Perfect for custom dungeons, adventure maps, and multiplayer servers where loot needs to be renewable.

⚙️ Core Mechanics

• First open – a random cooldown (between min and max minutes) is stored.
• Cooldown expired – the container's loot is completely regenerated on the next open.
• Custom loot tables – assign any vanilla loot table (e.g. minecraft:chests/simple_dungeon) using /dr setloot.
• Persistent data – cooldowns and custom loot assignments survive server restarts using PersistentDataContainer.

✨ Features

• Configure min/max cooldown in minutes (default 24–96 hours).
• Choose which container types are affected (chests, barrels, trial vaults).
• Clear inventory before refilling (configurable).
• Storage options: PDC (persistent) or in-memory Caffeine cache.
• Protection system – prevent breaking containers while on cooldown (with bypass permission).
• Tab completion for subcommands and all vanilla chest/dispenser loot tables.
