Opencompositions/components/char-slam-explode.html and copy what is inside into your own composition.
A component has no size or duration of its own. It takes both from the composition
you paste it into.
Variables
Every one of these has a default, so the piece works untouched. Set the ones you want to change on the element:| Variable | Default | Accepts | What it does |
|---|---|---|---|
text | Impact | string | Text split into glyphs for the scatter and slam. |
accent | green | green, blue, violet | Headline and glow color. |
spread | tight | tight, wild | Distance and rotation of the scattered glyphs. |
data-variable-values on the element that mounts it. These are the
defaults, so this behaves exactly like the preview above until you change one:
<div
data-composition-id="char-slam-explode"
data-composition-src="compositions/components/char-slam-explode.html"
data-variable-values='{"text":"Impact","accent":"green","spread":"tight"}'

<!--
char-slam-explode: HyperFrames video primitive
A headline begins as individually scattered glyphs, holds the explosion,
then reassembles with an overshooting slam and a deterministic three-frame
stage shake.
Variables:
text: headline copy
accent: green, blue, or violet headline color
spread: tight or wild scatter distance
Envelope, fixed IN and OUT with elastic HOLD:
IN_BASE = 1.64s, scattered hold, staggered return, and landing shake
HOLD = max(0, D - IN - OUT), subtle drift followed by 0.30s stillness
OUT_BASE = 0.40s, composed headline fades and scales down
If D is shorter than IN_BASE + OUT_BASE, IN and OUT compress together.
The timeline is never time-scaled.
The scatter table was generated at build time from fixed LCG seed
0x0c5e2026. Runtime code only reads the authored table.
Mount contract: the runtime clones only this template. #root fills the host
box, establishes the container query basis, and has no data-width or
data-height. One paused timeline registers under the literal
char-slam-explode key.
