ChunkCarts

Minecarts load the chunks they travel through, so you can send items across long distances on a server where nobody is standing at the far end. Closed and looping tracks stop loading automatically.

The guarantee

On the default settings, a minecart cannot be used as a chunk loader. A journey is only allowed to continue while the cart is making progress away from where it set off, so a loop, a shuttle, or an unwatched furnace cart runs out of slack and gets released.

There is one way to turn this off: enforcement: PERMISSIVE, a single setting with a warning printed at every startup. Set it only if you trust everyone who plays on your server.

Full write-up and a five-minute test you can run yourself: see the wiki.

Commands

One permission, chunkcarts.admin, held by operators by default. /ccarts is an alias.

• /chunkcarts list: active journeys, and which chunks are held and why
• /chunkcarts reload: re-read config.yml without interrupting running journeys
• /chunkcarts debug: toggle per-poll logging

FAQ

• Needs installing on clients? No. Server side only.
• Works with TrainCarts / Create / other rail mods? Untested. It watches minecart entities and doesn't touch rail behaviour, so it should coexist.
• Works on Folia? No, deliberately.
• Works on Spigot? No. Paper or a Paper fork only.
• Needs Fabric API? Yes on Fabric, hard dependency. No dependencies on NeoForge, Forge, or Paper.
• Adds items, blocks, or recipes? No.
• Alters cart speed or behaviour? No.
• Player facing? Only through admin commands. No player UI.
• Anything lost if a journey ends early? No. The cart stays exactly where it stopped, contents intact.
• Survives a server restart? Yes, journeys persist and resume.

Configuration

config.yml documents every setting inline. Defaults are the recommended settings; the file can be left alone.

• enforcement: STRICT (default) or PERMISSIVE
• departure-requirement: PLAYER_SEEN (default), PLAYER_ONLINE, or NONE
• progress-slack-chunks: loop detector tolerance, default 16
• journey-cooldown: default 10m, waived if a player has touched the cart since

In STRICT mode, the abusable settings are clamped to sane ceilings rather than trusted.

Full default values and explanations on the wiki.

Platform support

Paper and Paper forks, Fabric, NeoForge, and Forge. Fifteen game versions, 1.21 through 26.2 (1.21.2 excluded).

• Fabric requires Fabric API.
• Paper support is Paper only, not Spigot. It relies on Paper's asynchronous chunk loading, so it refuses to run on Spigot rather than degrade silently.
• NeoForge and Forge have no dependencies.

Licence

LGPL-3.0-or-later. Free to include in any modpack, public or private, free or paid, without asking. Modified public forks must use a different name and mod id. Full terms on the wiki.

Metrics

Reports anonymous stats to bStats: server software, game version, player count, and your enforcement/departure-requirement settings. No player data, world data, IPs, or coordinates. Set metrics: false to opt out.
