@roost2d/effects

Renderer-neutral timed effects, easing, shake, particles, trails, and pooling.

npm install @roost2d/effects

import { scalePop } from '@roost2d/effects';
const effect = scalePop(target, 0.2, 180);
effect.update(deltaMs);

sampleProceduralEffect deterministically samples generic beam, slash, projectile, burst, and trail descriptors. Descriptors can name a socket or attachment origin, choose following or detached space, describe linear or arcing two-dimensional trajectories, and request either a procedural visual or an exact attachment clone. Renderer adapters can therefore show the same effect from a live clock or an export timestamp.

Effects mutate small structural targets rather than importing a renderer. Recycle them with EffectPool, which is distinct from the general-purpose ObjectPool in @roost2d/core. Effects guide.
