airlock_pump

The pump looks up for the airlocks automatically based on airlock_pump_distance_limit and airlock_group_distance_limit values. When placed, the dir value (direction where the pipes are coming from) is considered as a direction towards the station (internal). The opposite direction is external. The airlock then tries to find airlocks or walls towards these directions until airlock_pump_distance_limit number of tiles reached. When it finds a valid object, then it tries to find airlocks, in directions perpendicular to the found tiles. And then adds them to the corresponding group (external/internal) until airlock_group_distance_limit number of tiles reached

Example scheme of a valid configuration: A-----W A-----A W--P--A W-----W A-----W

Where: A - airlocks W - walls P - pump A vent, scrubber and a sensor in a single device meant specifically for cycling airlocks. Ideal for airlocks of up to 3x3 tiles in size to avoid wind and timing out.
