Fluid trait reference

Fluid phases, flags, traits and container descriptors.

Edit an existing fluid at data/<fluid-namespace>/fluid_property/<fluid-path>.json. The required outer fields are listed below. See Datapack Settings for loading and replacement behavior.

Outer fields

FieldMeaning and defaultRange
typeFluid phase: liquid, gaseous, or plasma.
colorFluid display tint as an integer or #RRGGBB.−2³¹ to 2³¹−1 or #RRGGBB
symbolFluid hazard symbol shown in the UI.
temperatureFluid temperature used by thermal behavior.−2³¹ to 2³¹−1
nfpaHealth, flame, and reactivity ratings.
flagsOptionalStateless trait names from the table below.
traitsOptionalMap of parameterized traits.
containersOptionalMap of container descriptors.
sharesOptionalFluid-tag references accepted as equivalents by loose tanks.

Stateless flags

FlagEffect
gaseous_artEnables gas handling by flare and tank systems.
viscousUses viscous fluid handling and flow behavior.

Foreign-fluid equivalence

shares is one hashed fluid-tag reference such as "#c:diesel" or a list of references. Loose/code-typed tanks accept tag members and lock to the first arriving fluid. Explicitly selected tank types and ducts use the exact fluid; outputs stay NTM fluids.
