Replace the flat level-grid level select screen with a campaign-based
map view. Levels are grouped into themed campaigns (e.g. "Sunny Suburbs",
"Dusk Junction") each with its own background art and node positions
rendered along a Catmull-Rom spline ribbon.
Key changes:
- Introduce CAMPAIGNS array in src/data/levels/index.js with helpers for
campaign/level lookup.
- Add src/data/levels/positioning.js for auto-layout S-curve generation
and Catmull-Rom spline sampling.
- Rewrite LevelSelectScene.js to render per-campaign maps with animated
node entrance, idle pulse on the current level, hover states,
tool-tips for locked levels, and ← → / P keyboard navigation.
- Remove the now-unused LevelCompleteScene; scores now record progress
and return directly to the map via LevelScoreScene.
- Add map assets (campaign backgrounds, node/flag/tag sprites) and
manifest entries with a documented 960x540 centered-canvas convention.
- Add src/util/mapArt.js for shared map geometry constants and scaling.
Introduce LevelScoreScene to display a choreographed score breakdown (base score, per-kid results, time bonus) using a frozen snapshot of the win condition.
Replace generic icon_kid in the HUD with individual kid portraits that update based on each kid's specific status (aboard vs. ejected).
Extract _formatTime to a shared utility used by both PlayScene and LevelScoreScene.
Add audio assets for the scoring sequence.
- New browser level editor (editor.html + src/editor/): assemble levels
from snap-together section generators (flat/inclines/hills/ditch/jump)
with a live canvas preview, metadata form, and export to ready-to-drop
levelNN.js source; example export registered as level04.js.
- Add parallax background sprites (bg_far/mid/near).
- Bus retune: softer, bouncier suspension (stiffness 0.45->0.35, damping
0.08->0.035, travel 12->30, restitution 0.3->0.45) with wheel rest
point raised 22->34 for a bouncier stance; drive force cut ~60%
(0.011->0.0045) for a much longer runway and lower top speed.
- Gravity 1 -> 0.675 for ~1.5x hang time off jumps; constraintIterations
2 -> 10 so the soft wishbone springs converge within one step.
- Bus: clamp each wheel to the underside of its wishbone anchor line on
every matter afterupdate, fixing wheels punching through to the
mirrored solution and sticking high on the chassis after hard impacts;
add no-op destroy() for the world listener.
- CameraRig: speed-driven horizontal lookahead (bus framed ~10% from the
left edge at rest, out to 1/3 of the screen at speed) via followOffset;
PlayScene scales the g-force grace period to 5.5s for the new gravity
and calls the new update()/destroy() hooks.
- Extend level01's terrain runway by 30x.
