- Expand smash-items spritesheet from 6 to 12 frames (8x2 grid) with new trash can, tent, and cat props plus their smash sound effects
- Expand bonus-items spritesheet from 12 to 18 frames (9x2 grid) with new spray paint and backpack collectibles plus their firework sounds
- Add level12 ("Curb Check") as a designed level and levels 13-20 as placeholder stubs to fill campaign 2's 10-level map
- Give campaign 2 a custom 3-row serpentine layout on the level select screen to differentiate it from campaign 1's two-lane design
- Update editor preview rendering to handle multi-row spritesheet grids and expose the new item types in the placeables panel
- Extend bonus items spritesheet from 9 to 12 frames (add flour + 2 firework objects)
- Add `flour` type to BONUS_ITEM config with warm off-white/tan color palette and firework variant (2-3x scale, half opacity for dust cloud effect)
- Implement per-type firework variants in BonusItemManager._explode() - particles can now have varied sizes and alpha while maintaining standard physics body size
- Add flour SFX asset (bonus-flour.mp3) and preload it
- Update editor to support placing flour bonus items with appropriate icon, color, and sprite frame
- Update all documentation (README, sprites.md) to reflect the new bonus item type
Additionally:
- Add campaign 2 bus physics customization: grippier tires (higher friction coefficients) and stiffer/less-damped suspension for bouncier ride
- Thread per-campaign wheel friction and suspension parameters through Bus entity from themes.js
- Redesign level11 with shorter course, fewer kids (4 vs 3), tighter time limit (42s vs 119s), and flour bonus items replacing most cash/CTC/guitar
Campaign 2's larger wheels now hang further under the chassis via a new `wheelRestOffsetY` theme knob (42 vs 34 design units), making the bus visibly sit taller. The wishbone anchor and initial wheel position derive from this per-campaign offset, so both size and mount point stay correctly centered on the axle line.
- Add `BUS.wheelRestOffsetY2` in config
- Expose `wheelRestOffsetY` in theme `bus` blocks (default = campaign 1)
- Use themed offset in Bus constructor for anchor and wheel placement
- Update docs/comments to explain the lift-kit behavior
- Introduce `bus_wheel_2` asset and register it in the asset manifest
- Add `BUS.wheelRadius2` config for the larger wheel radius
- Extend themes with a `bus` block to select wheel texture and radius per campaign; campaign02 uses the new bigger wheels while keeping the same axle center
- Make `Bus` accept a bus theme parameter and use provided wheel texture/radius when creating wheels
- Update `PlayScene` to pass the active theme's `bus` settings into the Bus constructor
- Document the new per-campaign bus art/sizing behavior in sprites.md
- Add per-item sound keys to `SmashItemManager` and `BonusItemManager`, playing a dedicated clip on smash/collection (load-tolerant via `cache.audio.exists`)
- Preload new FX clips: `smash-{tv,chair,cone}` and `bonus-{cash,ctc,guitar}`
- Rebuild level07 terrain/layout with updated items, bonus placements, goal, and camera bounds
- Move level01 item positions to match new layout
- Update smash-items sprite sheet (PNG/PSD)
Introduces a new "bonus item" system alongside the existing smashables:
- **Gameplay**: Floating collectible prizes (CTC box, guitar, cash) that the bus passes through with zero physical response. On first contact, the item pops (scale-up + fade) and spawns a radial burst of tinted firework particles that arc down under gravity, settle on terrain, and fade out. Each collected item scores 100 points on the end-of-level tally.
- **Config**: `BONUS_ITEM` in `config.js` holds all tuning knobs (particle count, speed range, spin, lifetime, per-type tint palette, pop scale/duration). `SCORE.perBonusItem` added.
- **Entity**: New `BonusItemManager` class owns static sensor bodies for each bonus item, detects bus collisions, and orchestrates the pop + firework burst animation. Particles are real Matter bodies exempted from bus/kid collision so they can land on terrain without affecting gameplay.
- **Editor**: "Smashables" section renamed to "Placeables" with a kind toggle (Smashables vs Bonus items). Bonus items are float-only with no gravity option. Preview map, click-to-place, item list, and export all support both kinds. `splitPlaceables()` in `levelBuilder.js` splits the unified editor list into the two level arrays (`items` / `bonusItems`).
- **Levels**: Levels 2–6 updated with bonus item placements (and some additional smashable items).
- **Assets**: New `bonus-items.png` spritesheet (9 frames: 3 bonus items × [item + 2 firework objects]) registered in the asset manifest.
- **Score screen**: `_revealBonus()` method in `LevelScoreScene` displays collected bonus count and points, skipped when zero.
The previous fix only exempted the bus's `busCategory` from smashed item collisions, leaving items still colliding with and ejecting kids riding at the open top of the compartment. This commit:
- Adds `~this.bus.kidCategory` to the initial collision filter in `_buildItem`, so new smash items are ghost-to-kids from creation
- Updates the post-smash mask update to also clear `kidCategory` (previously only `busCategory` was cleared), preventing a regression where item↔kid collisions would silently re-enable after the smash animation
Items remain solid against terrain and other props, preserving normal landing/physics behavior while ensuring their impact can no longer contribute to ejecting kids.
- New SmashItemManager entity that spawns items from level data, detects bus contact, swaps to smashed frame, and applies up-and-forward impulse with tumble
- Add `SMASH_ITEM` config block for launch speed/angle/spin, density, friction, restitution, and float height
- Extend asset manifest and spritesheet (6 frames: intact/smashed TV, chair, cone)
- Level editor gains "Smashables" section to place/delete items via click on preview map; exports `items` array in level data
- Level editor can now import bundled or file-based levels, preserving exact terrain while locking section editing; metadata and items remain editable for re-export
- Score scene reveals smashed item count as a bonus line (+50 each) between kids and time tally
- PlayScene wires SmashItemManager lifecycle and passes smashedCount to score scene
- README documents smashables feature, editor workflow, and import behavior
- Remove physical ceiling fixture; compartment top is now intentionally open
- Kids eject when passing above the top and re-board when falling back down
- Add KID.ceilingReboardDelayMs to prevent accidental catches from residual
downward drift immediately after ejection
- Introduce a one-shot `ejected` latch to prevent kids who landed outside
the bus from being pulled back in later
- Replace `isSettledRelativeToChassis` with `_isMovingDownwardIntoCompartment`
to verify downward chassis-relative velocity
- Add "kid_reload" sound effect on successful re-boarding
- Update comments across config, Bus, Kid, and KidManager to document the
new position/velocity-based architecture
Add four new section types to the level editor:
- dropOff: instant vertical drop with gentle downward tail
- gap: flat lead-in, x-gap, flat landing at same height
- lip: flat run into a steepening (t²) kicker ramp
- dropGap: like gap but landing is well below takeoff
Fix Terrain physics body generation to extrude straight down from
segment endpoints instead of using rotated rectangles. A previous
perpendicular-offset approach caused near-vertical segments (dropOff
cliffs) to balloon physics bodies sideways under adjacent terrain,
making the bus ride above the drawn ground.
Update level03 ("Mind the Gap") to use editor-generated terrain data.
Generalize levelBuilder smoothing to detect gap-shaped sections
(structurally via takeoffPoints/landingPoints) rather than by type
string, so future gap types work automatically.
Correct the rectangle center offset calculation in Terrain to account
for both X and Y components perpendicular to each segment. Previously,
only the Y offset was applied, causing physics bodies to shift sideways
on sloped terrain. This fix resolves the bus visibly riding above or
through the ground on non-flat segments.
Also adds background and logo assets.
- Add `isSettledRelativeToChassis()` to measure settling speed relative to the bus instead of absolute world velocity, allowing kids resting inside a moving bus to re-board properly
- Gate re-boarding on being within the compartment's horizontal width to prevent false positives from kids resting on the ground at the bus's height
- Use a separate settling timer (`_slowSinceRelative`) to prevent interference between absolute and relative settle checks
- Increase `compartmentWallThickness` to 16 for better physical collision response against fast-moving kids
- Add checkered finish line entity with rippling flag pole (purely visual)
- Add three kid fall voice clips with random playback on kid ejection
- Add load tolerance for optional voice assets matching voiceLine.js pattern
- Preload kid fall sounds in PreloadScene and wire into KidManager
Replace flat green ground fill with layered subsoil/road/foliage bands
that match the parallax background palette. Add pebble texture on the
road surface and sparse grass tufts along the edge for visual depth.
Use a hash-based PRNG instead of Math.random() so decorative elements
remain consistent across level rebuilds.
The level now only fails on "all kids lost" once every ejected kid has
settled outside the bus (restSpeed/settleDuration hysteresis) or fallen
past the camera bounds, giving a rescue window after a jump. Also fails
when the bus itself drops below the level, and guards the compartment
clamp with a distance radius so far-away kids aren't yanked toward the
bus.
Ejection used to be g-force-triggered, but the suspension isolates the
chassis from shocks so the old threshold was effectively unreachable -
kids were never actually being ejected. Instead the bus now carries an
invisible three-sided box (floor + left/right walls, deliberately no
ceiling) pinned to the chassis with rigid constraints. The fixtures are
standalone bodies in a dedicated kid collision category, not compounded
into the chassis, because Matter only consults the root body's filter
on compounds, so only standalone bodies can be made to collide with kids
while the chassis part stays exempt.
KidManager now checks each kid's rotation-corrected chassis-local
position every physics tick and flips state in both directions: crossing
above the open top marks the kid ejected (light custom gravity,
kid_ejected texture), and drifting back down through it re-marks the kid
aboard. A per-tick hard clamp keeps kids from tunneling through the
floor/walls on a fast hit. Seat constraints and the settle timer are
gone - containment is purely physical collision. GForceMonitor is
demoted to a debug-only readout for landing diagnosis.
Kid art is now 5-frame spritesheets (one distinct kid per seat), with
the frame picked by seat index in Kid.js, and render order is fixed with
explicit depths (kids 1, bus chassis/wheels 2).
- Ejection: drop GFORCE.ejectThresholdG from 6 to 0.5 - the bouncier
suspension isolates the chassis from shock, so the old threshold was
effectively unreachable and kids were never actually being ejected.
Ejected kids now pop straight up through the roof (ignoring chassis
velocity/tilt) and fly under a lighter gravity (KID.ejectedGravityScale
0.35, applied via KidManager's beforeupdate handler) for a floaty,
Snuggle-Truck-style arc.
- Cut maxLeanAngularVelocity and leanTorqueStep in half for a slower,
more gradual lean that's easier to fine-tune mid-air.
- Parallax: far layer is now screen-fixed, scaled uniformly (no stretch),
and pans exactly once from start to goal by level progress; mid/near
layers are bottom-anchored and tiled at their own uniform scales. Kids
render at depth -1 so the bus always draws over them.
- Level builder: size camera bounds to the level's actual terrain min/max
Y (with padding, 1000px floor) instead of a fixed 1000 height, so long
runs of declines no longer push the bus below the camera's reach.
- Add level 04 "Mega Drop" (5 kids, extended terrain ending in the mega
drop 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.
Throttle/brake now apply a direct, ground-only force to the chassis on
top of spinning the wheel, since friction-mediated propulsion alone
couldn't reach a satisfying top speed. isGrounded() checks the engine's
live collision pairs instead of tallying start/end events, which left a
counter permanently stuck above zero when crossing segment seams and
turned airborne throttle into a rocket thruster.
Kid.destroy() and GForceMonitor.destroy() no longer call
matter.world.removeConstraint()/off(): by the time a scene's 'shutdown'
handler runs, the Matter World plugin has already torn down and nulled
this.matter.world, throwing 'Cannot read properties of null'. Matter's
World#shutdown() clears all bodies/constraints/listeners itself anyway,
so both removals were redundant, not just unsafe.
