Tube Logistics

The most basic Item Tube transports items along its length, and where a tube splits, the direction for each item is chosen at random. A routing network forms once a Routing Controller is set beside a Routed Item Tube, and the tubes linked into that network then carry extra abilities that ordinary tubes lack. Storage inventories placed next to provider tubes can be drawn on by the rest of the network, which lets a set of chests act as one shared store.

Item Requester Tubes keep a specified item at a chosen amount in the inventories next to them. Manual Requester Tubes let players look at the items the network can supply and make individual requests. Storage Route Item Tubes act as a destination for items that have no route, and unrouted items entering the network are placed into adjacent inventories.

Tube Logistics requires Fabric Language Kotlin. It is client and server, so the server and every player need the mod. Files are published for Fabric, for 1.16.4 and 1.16.5, and the mod is released under the MIT License, so the source code is public and open source.
