FAQ

Does it need to be installed on clients?

No. Server side only. Clients can join without it.

I installed it and nothing happens. Why?

If simulation-distance is high and your rail lines are short, players already load the whole route and ChunkCarts has nothing to add. It still tracks journeys, but every chunk it would hold is one a player is holding anyway, and those are free, so they do not count against the travel budget either.

ChunkCarts is for long routes on servers with a modest simulation distance. This is also why Verify It Yourself starts by setting simulation-distance=2.

Does it work with TrainCarts, Create, or other rail mods?

Untested. It watches minecart entities and does not modify rail behaviour, so it should coexist, but no claim is being made.

Does it work on Folia?

No, and this is deliberate. See What ChunkCarts Will Not Do.

Does it work on Spigot?

No. Paper or a Paper fork. The mod refuses rather than running badly. The reason is on Platform Support.

Does it need Fabric API?

On Fabric, yes, and it is a hard dependency. On NeoForge, Forge and Paper, no dependencies at all.

Does it add items, blocks, or recipes?

No. Nothing is added to the game. It changes only which chunks stay loaded while a cart is moving.

Does it alter cart speed or behaviour?

No.

Can players see it?

Only through the admin commands. There is no player facing UI, and the one optional player facing feature, messaging the last person who touched a stranded cart, is off by default.

What is the performance cost?

Journeys are polled every 10 ticks by default, and there is a min-tps floor of 18.0 below which the mod stands down. max-concurrent-journeys defaults to 16. All three are on Configuration.

Is anything lost if a journey ends early?

No. The cart stays exactly where it stopped with its contents intact. Every reason a journey can end is listed on Journey Outcomes.

Does it survive a server restart?

Yes. In flight journeys are persisted and resume.

Can I use it in a modpack?

Yes, public or private, free or paid, without asking. See Licensing and Redistribution.

How do I turn off the loop detection?

enforcement: PERMISSIVE. Understand what it costs first: minecarts on your server can then be used as chunk loaders by anyone able to build a loop of powered rail. See Configuration.
