Module fluid 

Fluid behavior system.

This module handles fluid mechanics: spreading, flowing, waterlogging. Based on vanilla Minecraft’s FlowingFluid system.

TODOs

• TODO: Remaining entity fluid side effects: drowning, splash particles/sounds.
• TODO: Block item drops when water destroys blocks (cactus infrastructure merged, needs implementation).
• TODO: Lava random tick fire spread.

Modules

collision

Fluid collision and passability logic.

conversion

Fluid state computation and source conversion logic.

flowing_fluid

Shared logic for flowing fluids (Water, Lava).

fluid_behavior

Fluid behavior trait and related types. Fluids like WaterFluid and LavaFluid implement this trait to inherit behavior.

fluids

Concrete fluid implementations: EmptyFluid, WaterFluid, and LavaFluid.

spread_context 🔒

Spread calculation context for fluid flow optimization.

state

Fluid state <-> block state conversions.

Structs

Fluid

A fluid type definition (e.g., water, lava, empty).

FluidState

A fluid state instance with amount and falling properties.

Traits

FluidStateExt

Extension trait for FluidState type-checking methods.

Functions

is_lava_fluid

Returns true if the given FluidRef is lava (including flowing lava).

is_water_fluid

Returns true if the given FluidRef is water (including flowing water).
