Particle burst粒子迸发
- from a single point
- radial
- brief
A ring of dots flies outward from a single point, slowing and fading until it is gone in under a second. This is the base of the family: confetti, fireworks and sparks are all this same burst with a different launch arc and a different force acting on it.
When to use it
Use it for the one-off moment something succeeds: a payment, a finished task, an unlock. One per screen at a time, and never on a loop — the moment particles become a backdrop, celebration becomes noise.
Parameters
on success · 22 particles · radius 34→96px · opacity 1→0 · 780ms ease-out
Recipe
Particle burst → on success · 22 particles · radius 34→96px · opacity 1→0 · 780ms ease-out
One sentence for your AI
Build a particle burst: spawn 22 dots from a centre point, each flying out at a 360/22 slice of the circle, radius going 34px to 96px while opacity falls 1 to 0, over 780ms ease-out. Animate transform and opacity, never left/top.
