Type Alias ParticleSpawnValue<V>

ParticleSpawnValue:
    | V
    | readonly [V, V]
    | ((rng: () => number, index: number) => V)

A spawn() override: one value for the whole batch, a pair each particle draws between, or a function called per particle

The function gets the system's random source and the particle's place in the batch, 0 to count - 1. A pair of points draws each component on its own, so two corners make a box.

Type Parameters

Example

sparks.spawn(10, {
  life: 2,
  size: [0.1, 0.4],
  startRotation: (rng: () => number) => rng() * Math.PI * 2,
});
sparks.spawn(8, { position: (_rng: () => number, i: number) => ringPoints[i] });
