- VictoryCamDirector: cinematic post-race camera system with shuffled
shot types (chase, orbit, front, trackside) and hard-cut transitions;
player can press ENTER to skip.
- Engine audio: per-racer engine hum (heavy/fast/medium) with pitch
tracking based on kart speed; engine-start sound at green light.
- Star power loop sound that stops when star expires.
- Positional audio: AI kart sounds (spin, hit, flatten) scale volume
with distance from player.
- Enhanced event sounds: item-use, boost, EMP, squash, bump, coin,
star now play appropriate SFX.
- Player kart autopiloted after finishing for victory-lap vignette;
race phase waits for entire field (up to 90s safety cap).
- EMP now emits target list for per-target shrink sounds; squash
collision emits event.
- Animated race results screen with staggered row reveals.
- Animated cup standings with running point counter and position
arrows; tweens rows to new ranks.
- Podium reveal: 3rd → 2nd → 1st staggered with confetti, count-up,
and CRT pulse; winner speech plays.
- Mode7 camera now tracks height and focal length; setCamera accepts
arbitrary poses for cinematic shots.
- New audio assets: engine-start/heavy/fast/medium/rev, kart-coin,
kart-flatten, kart-thump, kart-shrink, kart-spin, kart-hit,
kart-shell, kart-star.
- Add beach theme artwork and register paths in artwork JSON
- Implement AI rubber-banding that scales AI top speed based on gap to player
- Configure engine classes with varying rubber-band strength (Cruiser most forgiving, Turbo least)
- Balance racer stats: boost Kona top speed, reduce heavy racer accel/handling
- Update verification script to validate new rubber-banding configuration
Complete kart racing game featuring 12 procedurally generated tracks
across 3 cups, 9 unique racers with distinct stats, headless physics
simulation, and a secret track editor (?superkart-editor=1).
Core features:
- Mode 7 ground renderer with parallax horizon backdrops
- 12 hand-tuned tracks (speedway, beach, swamp, scrapyard, volcano, nightcity)
- 9-racer roster with balanced archetypes (all-rounder, drift pirate, etc.)
- Headless race simulation for deterministic AI and headless verification
- Item system (bolt, seeker, oil, turbo, overdrive, emp, coins)
- Position-weighted item roulette and rubber-banding
- AI opponents with skill-based driving and stuck-recovery
- Full track editor with live preview, validation, and export
- 275 verification checks covering schema, physics, AI soak, and determinism
