Liquid Tank

Passive buffer that holds any one liquid: water, oil, or a biome essence. It commits to the first liquid piped in.

Stats: Type Fluids · Storage: any liquid, 100 t

How to obtain: Requires the Liquid Tank research (Oxygen 400). Buy from the Shop for 900 cr.

Access: get_component(id) · Like every component, exposes .id and .name.

Methods

.outpost

The outpost where this building is deployed, as an OutpostRef.

.fluid()

The latched liquid id, or "" while empty/unlatched. Possible values: "", "water", "oil", "frozen_essence", "coastal_essence", "geothermal_essence", "volcanic_essence", "deep_essence", "brine", "raw_cryofluid", "cryofluid", "raw_quicksilver", "quicksilver". The tank commits to the first liquid it receives and holds only that until it drains to 0, then re-latches.

Returns: String

.level()

Current liquid stored in tons (0 to capacity()). At 0 the tank unlatches and can accept a different liquid next.

Returns: Number (tons)

.capacity()

Maximum tons this tank holds. Queryable rather than hardcoded.

Returns: Number (tons)

.fill_pct()

Fill fraction (0-1), shortcut for level() / capacity(). Common threshold in supply-control scripts.

Returns: Number (0-1)

.inflow_rate() / .outflow_rate()

Liquid arriving / leaving in t/h. 0 inflow = no upstream flow; 0 outflow = no downstream consumer drawing.

Returns: Number (t/h)

.is_full() / .is_empty()

Full: level() == capacity(), upstream source backpressured. Empty: level() == 0, unlatched, downstream starved.

Returns: Boolean

.liquid_in / .liquid_out

Generic FluidPort input and output. Neutral while empty: connect(...) with the provider’s stable machine id or display name, and the first exact liquid delivered latches the tank. The output provides the latched liquid to connected consumers.

.water_in / .water_out

Exact-fluid FluidPort properties that exist only while fluid() is "water" (the pattern generalizes to the latched fluid).
