Enum ForceField 

Source 
pub enum ForceField {
    Gravity([f32; 3]),
    Drag(f32),
    PointAttractor {
        position: [f32; 3],
        strength: f32,
        falloff: f32,
    },
}
Expand description

Force applied to every live particle each simulation step.

Variants§

§

Gravity([f32; 3])

Constant acceleration. World units per second squared.

§

Drag(f32)

Velocity-proportional drag. Coefficient is the fraction of velocity lost per second.

§

PointAttractor

Pull toward a world-space point. Acceleration scales as strength / (distance + falloff)^2.

Fields

§position: [f32; 3]

World-space position of the attractor.

§strength: f32

Acceleration coefficient. Negative values repel.

§falloff: f32

Distance offset that softens the singularity at the center.
