Burst

Full motion specification

How the movement works

Use it to mark the instant something is triggered or achieved, such as a like, a success or a correct answer.

1. 01One burst per 2.35 s. A heart (size 46, 7 px outline) sits in the centre.
2. 02Anticipation: 0.3–0.5 s, scale 1→0.7 (quadratic ease-in-out).
3. 03Trigger at 0.5 s: the heart fills with coral and scale returns 0.7→1 with spring 1 − e^(−6.5t)·cos(16t).
4. 04Ring: yellow, radius 44→90 while line width goes 16→0, over 0.6 s with quintic ease-out.
5. 0510 radial lines (yellow/mint alternating, width 9): outer end radius 64→130 (y scaled 0.82); length 36 shrinks to 0 between 0.22 and 0.7 s after the trigger.
6. 0610 dots (coral/blue alternating, radius 8→4.8): radius 58→150 on an ellipse (x ×1.45, y ×0.78), fading out 0.3–0.72 s after the trigger. The heart fill fades at 1.92–2.2 s.
