Basic Adjacency Connections

Basic connections use the โ€œBasic Adjacency Connectorโ€ script and are ultimately the simplest connection type.

These basic shapes are defined below:

O - A variant with no connections.

U - A variant with 1 connection, to the north.

I - A variant with 2 connections opposite of each other, 1 to the north and 1 to the south.

L - A variant with 2 connections adjacent to each other, 1 to the north, and 1 to the east.

T - A variant shaped like a โ€œTโ€, with 3 connections, 1 to the south, east, and west.

X - A variant shaped like a โ€œ+โ€, with 4 connections, 1 to the north, east, south, & west.

These pieces can be rotated to create many various shapes. This works fine for objects that do not have corner connections (pipes, cables, etc.), but this wonโ€™t suffice for objects that do (tables, walls, etc.) because it will leave gaps where the corners meet.

Examples of Basic Connections


These heavy-duty high-voltage cables are only used between station engines and related machinery.

Two โ€œIโ€ shapes can cross each other while maintaining separate circuits; they do not have a junction box like the similar โ€œXโ€ shape.

Though similar to wires, wires are more complex (see the โ€œWire Adjacency Connectionโ€ section for more details).

Conveyor Belts

Currently, these do not use a โ€œTโ€ or โ€œXโ€ shape so we can either add those or resolve how a straight piece may connect in such a situation as seen in the image (these may need to get their own unique adjacency connector in the future).

HE Pipes

Heat Exchange Pipes donโ€™t require an โ€œOโ€ shape.

They do however have an special โ€œIโ€ shaped called a โ€œJunctionโ€ which connects between the HE pipes and regular pipes on the 4th layer (see the pipe adjacency connections section for more info).
