# Canvas Procedural Animation

Use this skill when p5.js or Canvas is used for character-supporting motion: rain, snow, leaves, feathers, ambient particles, squash/stretch, or procedural walk cycles.

## Proven Pattern

p5.js runs setup once and redraws continuously through `draw()`. Keep animation state deterministic from time/frame values when rendering previews.

```js function setup() { createCanvas(1920, 1080); }

function draw() { const t = millis() / 1000; clear(); drawCharacter(width / 2, height / 2 + sin(t * 8) * 8); } ```

## Use For

- Particle/weather overlays. - Environmental motion. - Simple procedural bodies. - Effects that do not need individually authored SVG parts.

## Avoid For

- Complex facial acting where SVG/layered rig parts are easier to inspect. - Final renders that need exact frame determinism unless the runtime exposes frame-index control.
