Enum FalloffMode 

pub enum FalloffMode {
    Constant,
    Linear,
    InverseSquare {
        min_dist: f32,
    },
    SmoothStep,
    Annular {
        inner_radius: f32,
    },
}

How a force field’s strength falls off over distance.

Variants

Constant

Constant — no falloff, field applies uniformly within radius.

Linear

Linear falloff from max at centre to zero at radius.

InverseSquare

Quadratic falloff (1 / r²-like).

Fields

min_dist: f32

SmoothStep

Smooth cubic: 1 - 3t² + 2t³.

Annular

Field only applies outside a minimum distance and inside max_radius.

Fields

inner_radius: f32

Implementations

impl FalloffMode

pub fn factor(&self, t: f32, dist: f32, _radius: f32) -> f32

Returns a 0..1 multiplier given normalised t = dist / radius (0 = centre).
