Struct FluidPool 

pub struct FluidPool {
    pub position: Vec3,
    pub radius: f32,
    pub fluid_type: FluidType,
    pub depth: f32,
    pub age: f32,
    pub max_lifetime: f32,
    pub absorbed_count: u32,
}

A settled pool of fluid on the floor, providing area gameplay effects.

Fields

position: Vec3

Centre position (Y is FLOOR_Y).

radius: f32

Radius of the pool on the XZ plane.

fluid_type: FluidType

Type of fluid in this pool.

depth: f32

Depth of the pool (increases as more particles settle).

age: f32

Age in seconds since creation.

max_lifetime: f32

Maximum lifetime — pool evaporates after this (0 = infinite).

absorbed_count: u32

Number of particles that have been absorbed into this pool.

Implementations

impl FluidPool

pub fn new(position: Vec3, radius: f32, fluid_type: FluidType) -> Self

Create a new pool at position with initial radius.

pub fn absorb_particle(&mut self)

Absorb a particle into this pool, growing it slightly.

pub fn area(&self) -> f32

Area of the pool (circle approximation).

pub fn contains_xz(&self, point: Vec3) -> bool

Whether a world-space point (XZ only) falls inside this pool.

pub fn alive(&self) -> bool

Whether this pool is still alive.

pub fn life_fraction(&self) -> f32

Fraction of lifetime remaining.

pub fn color(&self) -> [f32; 4]

Base RGBA colour modulated by pool age.

pub fn update(&mut self, dt: f32)

Update pool age.

pub fn merge_from(&mut self, other: &FluidPool)

Merge another pool into this one (absorb its area/depth).

pub fn distance_to(&self, other: &FluidPool) -> f32

Distance between pool centres (XZ plane).
