Struct ParticleConfig 

pub struct ParticleConfig {
    pub emission_rate: f64,
    pub max_particles: usize,
    pub lifetime_min: f64,
    pub lifetime_max: f64,
    pub speed_min: f64,
    pub speed_max: f64,
    pub gravity: Vector2D,
    pub size_start: f64,
    pub size_end: f64,
    /* private fields */
}

The static configuration of a particle emitter, describing how new particles are spawned and how they evolve over their lifetime.

Every field is publicly settable, so a caller composes a config by starting from ParticleConfig::default and overriding the tunables it cares about before handing it to ParticleEmitter::create.

Fields

emission_rate: f64

The number of particles spawned per second while the emitter is active.

max_particles: usize

The maximum number of simultaneously live particles.

lifetime_min: f64

The minimum particle lifetime in seconds.

lifetime_max: f64

The maximum particle lifetime in seconds.

speed_min: f64

The minimum initial particle speed in world units per second.

speed_max: f64

The maximum initial particle speed in world units per second.

gravity: Vector2D

The constant acceleration applied to every live particle.

size_start: f64

The particle radius at birth in world units.

size_end: f64

The particle radius at death in world units.
