This reverts commit 153fc21. With no fallback in code, the deploy
crash-looped: Coolify keeps an entry for every variable compose.yml has
referenced, and empty entries appear to reach the containers as empty
values instead of the compose defaults.
compose.yml now holds each default as ${VAR:-default}, and the code keeps
no fallback values. The bot stops at startup on a missing or invalid
PORT or LOG_LEVEL, /addsticker refuses without STICKER_PACK_NAME, and the
renderer refuses to start until every RENDERER_* setting is a valid
value, listing each problem. Settings whose empty value means none or
all (MODULES, OWNER_ID, ADMIN_IDS, the API tokens) use ${VAR:-}.
The renderer's npm start and dev load .env when present, so a local run
works from a copy of .env.example.
BREAKING CHANGE: running outside compose now requires LOG_LEVEL and PORT
for the bot, STICKER_PACK_NAME for /addsticker, and every RENDERER_*
variable for the renderer.
The renderer's settings now read RENDERER_HOST, RENDERER_PORT,
RENDERER_MAX_CONCURRENT_RENDERS, RENDERER_RENDER_TIMEOUT_MS,
RENDERER_MAX_OPTIONS, and RENDERER_MAX_OPTION_CHARS, so they read as
renderer settings and cannot clash with the bot's variables, which
Coolify injects into every service. NODE_ENV keeps its standard name.
BREAKING CHANGE: the unprefixed HOST, PORT, MAX_CONCURRENT_RENDERS,
RENDER_TIMEOUT_MS, MAX_OPTIONS, and MAX_OPTION_CHARS are no longer read
by the renderer.
The renderer now runs only on the compose network with no published port
or domain, so a shared bearer token adds nothing. The renderer no longer
checks Authorization or requires API_TOKEN in production, and the bot no
longer sends a token.
BREAKING CHANGE: WHEELOFNAMES_API_TOKEN and the renderer's API_TOKEN are
removed. Never publish the renderer's port: its API is unauthenticated.
Brings back the Genshin-style meteor wish that /api/gacha rendered before pack-cards, under genshin names. It takes the same request as /api/gacha and returns the 7-second landscape MP4.
The scripted drag across the seal, the torn pack falling away, and the
card rising out of it now ease exponentially in and out. The pack keeps
pack-cards' 1.35s drop and hold, and the card still clears the pack when
the spin starts.
/api/gacha now renders the 6-second portrait pack-cards opening that was
served on /api/gachabeta. The Remotion meteor wish, its timeline, and the
beta route are removed, and the pack-cards renderer and page take the plain
gacha names.
BREAKING CHANGE: /api/gachabeta is gone, and /api/gacha returns a 6-second
portrait video (360x640 for width 640, 480x854 for width 854) instead of the
7-second landscape one.
/api/gachabeta now returns a portrait video with the requested width as its long edge: 640 renders 360x640 and 854 renders 480x854. The request body is unchanged, and /api/gacha stays landscape. The pack sits higher so it stays in frame while the card rises.
/api/gachabeta now tears open a pack-cards collectible pack whose card
shows the request's label, the same B/A/S rank as /api/gacha, and one
star per rarity level; rarity also picks the card material and the pack
colour. pack-cards animates on the browser clock, so the route drives a
shared headless Chrome in deterministic mode over a debugging pipe,
steps virtual time frame by frame, tears the pack with a scripted drag,
and encodes the captured frames with Remotion's bundled ffmpeg. The
page and package are served from disk with all other requests blocked.
The browser stays alive per process and is warmed at start-up, because
the first render compiles the pack's WebGL shaders in software. The
Remotion beta composition and its scene code are removed. pack-cards is
installed from a GitHub tarball pinned to a commit, since it has no npm
release and a moving URL would break npm ci.
The beta splash card used a fixed SSS rank and six stars. It now uses the
same rarity info as /api/gacha: the rank letter (B, A, or S) on the emblem
and name plate, and one star per rarity level beside the caller's label.
The beta wish now cuts like an anime gacha game's six-star wish over 10.5
seconds: a dive through a painterly cloud vortex, a beam pass, a meteor
that stops inside a rainbow halo and bursts, a red flash, falling crystal
comets joined by a red meteor, a black emblem silhouette shedding shards
on a red disc, and a splash card with a name plate and six stars.
Cloud layers are painted once per roll onto a canvas with a seeded noise
displacement, so frames only move the baked image instead of running a
live SVG filter. The /api/gachabeta contract is unchanged.
The beta wish now renders an 8-second night sky over a snow-rimmed
mountain ridge, where coloured meteors glide down the diagonal. A hero
meteor in the rarity colour slows and burns out at the centre, where the
label appears under rank SSS. The toon cloud, comet, and perspective
camera are removed. The /api/gachabeta contract is unchanged.
The beta wish renders an 8-second astrology-themed night sky in toon
shading through a perspective action camera: it dollies toward a hero
cloud, a comet lights the cloud's rim from behind and bursts through it,
the camera chases the comet as its flare builds to a starburst, and the
label appears with an S, SS, or SSS rank. It shares the /api/gacha request
contract and render slots.
The meteor now flies in from the upper left and lands on the rank emblem,
so the impact burst becomes the badge reveal. The 5-star rainbow ring is
replaced by a rainbow sunburst of counter-rotating rays. Sky stars twinkle
with short bright flares and cross glints, and each roll draws a fresh
layout from a per-request seed that the route picks when the caller sends
none.
Measured from reference footage, the meteor sweeps in along a straight line
from the upper left at about 23 degrees and eases out exponentially to a
hover above the horizon, replacing the gravity arc. The trail is now a soft
beam that narrows into the head with ribbons fanning along it, every tier
gets the horizontal lens flare, and sparkles drift above the beam.
The meteor now follows a ballistic parabola: constant horizontal speed and
vertical speed growing under gravity solved from the launch and impact
points, so it climbs slightly, bends over, and dives while speeding up. The
trail samples past positions in time so it lengthens with speed, the head
stretches along its velocity, and sparks inherit the meteor's velocity and
fall under their own gravity.
Every beat now scales from a per-tier effects table: 4-star adds a bigger
meteor, lens flare, impact shake, and double shockwave; 5-star adds a
rainbow halo before landing, a gold sky flood, a starburst, counter-rotating
rays, falling sparkles, and an emblem sheen. The emblem shows the rank
letter instead of the label's first character.
A meteor coloured by rarity falls across a night sky, lands in a white
flash, and the label is revealed with its stars popping in. The caller
picks the result and rarity; the route only draws it. Renders as silent
H.264 so Telegram plays it as an animation without GIF banding, and
shares the render slots with /api/gif.
Draw the winner outline as an unfilled pie after every slice: slices paint
in index order, so the next one covered the shared radial edge and the
outline stopped short of wrapping the wedge.
Derive the announcement colors from the winning slice - its own color as
the chip, a deepened version as the frame and the wedge outline - instead
of a fixed dark chip that read as unrelated to the wheel.
Raise the confetti above the announcement so the burst is no longer hidden
behind it, and steepen the launch fan so the field arcs around the name
rather than settling on it: horizontal reach is vx / drag, which parked the
flat fan at mid-canvas. Measured over the hold, particle samples inside the
pill drop from 22.4% to 6.2% while disc coverage holds at 85.5%.
The animation's weakest moment was its final frame, which is also the frame
most chat clients show as the GIF's poster image.
Celebration:
- Confetti launches from two cannons framing the wheel instead of bursting
inside the hub, using closed-form drag ballistics so chips decelerate and
flutter rather than flying a clean parabola. The field previously drained
from 70 particles to 3 before the GIF ended; it now stays populated, and a
2500ms hold ends with 68 on screen instead of 0.
- The opening frame rendered at opacity 0, throwing away the one frame where
particles are still clustered. Removed the fade-in and made the tail
frame-relative and quantized to bound its palette cost.
- Chips streak along their direction of travel in proportion to speed, faking
the motion blur a GIF cannot carry. A second volley, sized to the
celebration window, keeps long holds from thinning out.
- Each theme carries its own confetti palette. Slice colors are tuned to hold
dark text over a large area, which left five of six mono colors under 2.4:1
against the background and invisible at particle size.
- The winner's name appears over the hub during the hold. At a 200px chat
display the pointer is ~17px and a slice label ~9px, so the poster frame did
not say who won.
- Winner emphasis is an opaque stroke, not a drop-shadow. A filter on a Pie
paints outside the shape, so later siblings overpainted it and only one
neighbour ever showed the halo.
Motion:
- Turn count scales with the frame budget and slice width. A fixed 5 turns put
peak speed at ~40deg per frame regardless of option count, so 65 of 98
frames advanced more than a full slice at 32 options and the wheel appeared
to run backwards. Turn counts floor rather than round, since rounding up
reintroduces the aliasing, and stay integral so the winner still lands on
the detent.
- The spin launch now blends into the deceleration at a matched slope. The
previous curve started at maximum speed, and a naive ease-in jumped from 18
to 41deg per frame in a single frame.
- A damped recoil rocks the wheel into its detent, resolving to exactly zero
so the landing and the flapper's rest position are unaffected.
- The pointer is drawn as SVG with a real outline and a tick as slices pass.
clip-path had been discarding its border and shadow entirely.
Legibility:
- Labels flip by their rest-frame angle so every name reads upright in the
final frame. This reverses an earlier decision to leave them slice-aligned;
three of eight names rendered mirrored on a default wheel.
- Label text renders inside a promoted compositing layer, which switches
Chromium from LCD sub-pixel to grayscale antialiasing. Sub-pixel fringes put
2178 colored pixels into an all-grayscale theme and consumed 255 of 256
palette entries. Promoting the one rotating container rather than each label
keeps render time flat on dense wheels.
- Line boxes leave room for stacked Vietnamese diacritics and shrink to fit
rather than clipping.
- Slice colors are ordered for colorblind separation, and the last slice
avoids reusing the first slice's color when the option count leaves a
remainder of one.
Deterministic frame-based confetti fired from the wheel center during the winner hold, seeded by winner index and colored from the theme palette. Uses Remotion's random() so each GIF frame renders identically.
