Struct Particle 

pub struct Particle {
    pub source: Entity,
    pub age: f32,
    pub lifetime: f32,
    pub velocity: [f32; 3],
    pub size: f32,
    pub color: [f32; 3],
}

Particle component spawned by an Emitter.

Spawned particles are tagged with Billboard by the spawn system. The rendering system (T2 of #217) consumes those tags plus the size/color fields here.

Fields

source: Entity

Back-reference to the emitter entity that produced this particle.

age: f32

Time elapsed since spawn (seconds). Aged each tick by the system.

lifetime: f32

Total lifetime (seconds). When age >= lifetime, the particle is despawned.

velocity: [f32; 3]

Initial linear velocity (units/second). Consumed by the renderer or downstream movement systems.

size: f32

Particle size (renderer-specific units).

color: [f32; 3]

Particle color (linear RGB [0, 1]).
