gabrielmoreira 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.
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.
