Tubes Reloaded

Items are inserted into a tube block from a hopper, osmosis filter or similar source and carried to the nearest valid destination on the network. Insertion is refused unless the tube block is joined to a valid endpoint, so items never enter a network that cannot deliver them. A Tubing Pliers tool links two tube blocks remotely by right-clicking one and then the other, and tubes joined this way count as one block for routing. Tubing Pliers can also turn shunts, loaders, filters, osmosis filters and distributors to a new facing.

Several specialised blocks shape the flow. A shunt takes items from five sides and sends them out the sixth into the world or an inventory block, and it cannot receive items through its output side, which makes directing flow simple. A filter has one input side and one internal slot that holds a single item type; items must enter from the side opposite its output. A distributor lets each face act as either input or output, and items leave through an adjacent item-handling block that can accept them. Color tubes connect only to tubes of the matching color, and a loader opens a GUI so players can move items between their inventory and the network with shift-click.
