}

72-byte particle record; colors are finite linear-premultiplied RGBA.

Fields

position: [f32; 2]

Local center in design coordinates.

velocity: [f32; 2]

Units per second.

color: [f32; 4]

Linear-premultiplied RGBA, not encoded bytes.

size: f32

Nonnegative style size multiplier.

rotation: f32

Clockwise radians.

age: f32

Canonical seconds since birth, owned by the simulation.

lifetime: f32

Positive lifetime seconds, half-open at death.

index: u64

Stable nonrecycled emission index.

custom: [f32; 4]

User-owned values retained by snapshots.
