* Building editor
Add a Buildings tab to the Save Game Editor that lets users browse
all 16 buildings, preview them in 3D, and customize their properties
(sound, move, mood, variant) by clicking, matching the original game
behavior per character.
- Parse 16 buildings + nextVariant from save files instead of skipping
- Add serializer methods to patch building fields in-place
- Create BuildingRenderer (extends AnimatedRenderer) for 3D preview
with click animations from SNDANIM.SI
- Create BuildingEditor component with per-character click behavior
(Pepper: variants, Mama: sounds, Papa: moves, Laura: moods)
- Extract 18 building animations and 2 building sounds into asset bundle
- Fix centerAndScaleModel to account for scale in position offset
* Add Building Editor to February 2026 changelog
* DRY up renderer hierarchy: extract shared logic into base classes
Move duplicated animation tree utilities (findAnimatedNode,
evaluateNodeChain, findNodePath, evaluateLocalTransform),
click animation (queueClickAnimation, playQueuedAnimation,
buildRotationTracks), and raycast hit testing (getClickedMesh)
from PlantRenderer and BuildingRenderer into AnimatedRenderer.
Add loadTextures() and createMeshMaterial() helpers to BaseRenderer,
replacing identical texture-loading loops and material-creation code
across all four renderers.
PlantRenderer: 279 → 73 lines (-74%)
BuildingRenderer: 245 → 57 lines (-77%)
* Plant editor
Add Plants tab to the save editor for browsing and editing all 81 plants.
Click-to-customize based on selected character matches the original game
behavior (Pepper→variant, Mama→sound, Papa→move, Nick→color, Laura→mood).
Includes 3D preview with per-variant display tuning, click animations,
sound playback, and reset to defaults.
* Refactor shared animation code into AnimatedRenderer base class
Extract duplicated animation infrastructure (clock, mixer, animation
caching, raycaster, keyframe interpolation) from ActorRenderer and
PlantRenderer into a new AnimatedRenderer intermediate class. Extract
identical sound player code from both editors into createSoundPlayer()
utility. Fix PlantRenderer interpolateVertex bug where scale keys had
X incorrectly negated. Remove dead PLANT_ANIM_IDS export and redundant
textures.clear() calls.
* Extract shared editor CSS and fix vehicle nav spacing
Move duplicated preview, spinner, navigation, and side-button styles
from VehicleEditor, ActorEditor, and PlantEditor into a shared
editor-common.css. Standardize class names (nav-index, nav-name,
side-btn) and fix VehicleEditor part-info min-width (100px → 150px)
to match the other editors.
* Add carousel tabs and selection-based nav to save editor
Wrap save editor tab buttons in a Carousel to prevent overflow on
desktop. Carousel nav buttons now cycle through the selected item
(save slot or tab) instead of scrolling, with auto-scroll-into-view.
On mobile, tabs reflow with flex-wrap as before.
* Update February changelog with plant editor and carousel navigation
* Improve Lighthouse LCP and accessibility scores
Preload the LCP image (install.webp) from the HTML and add
fetchpriority="high" so the browser discovers it before JS executes.
Use a <main> landmark for the primary content container to satisfy
the "document has a main landmark" accessibility audit.
* Add actor editor with animated 3D character preview
Browse and customize all 66 game actors with a Three.js rendered preview
featuring skeletal walk cycle animations. Click interaction matches the
game's character-dependent behavior (Pepper=hat, Nick=color, etc.).
- Parse WDB global parts and global textures for character assembly
- Parse and serialize character data (66 entries x 16 bytes) in save files
- AnimationParser for .ani binary format with hierarchical keyframe evaluation
- Full g_cycles animation table (11 types x 17 animations) driven by move/sound
- Per-mesh texture support for hats, torso, and face textures
* Extract BaseRenderer to deduplicate actor and vehicle renderers
- Extract shared Three.js setup, lighting, texture, geometry, and
animation loop code into BaseRenderer base class (~170 lines)
- Deduplicate WdbParser.parseGlobalParts via parsePartData delegation
- Consolidate lego brown/lt grey into shared LegoColors constant
- Remove dead code: updatePartColor, SUFFIX_NAMES, CharacterType,
getCharacterType, partToLODIndex, unused imports and re-exports
- Simplify updateCharacter and resolve methods by removing unnecessary
defensive checks on frozen data and bounded UI inputs
- Extract actorKey helper in ActorEditor to deduplicate key computation
- Delete unused animations/manifest.json
* Add reset to default button for actor editor
Compare each actor's character state against ActorInfoInit defaults
and show a reset button when any field differs. Resets all 10 fields
(sound, move, mood, hat, colors) in a single save round-trip by
extending updateSaveSlot to accept batch character updates.
* Show full character names in actor editor
Add ActorDisplayNames lookup with names from savegame.ksy doc comments
(e.g. "Pepper Roni", "Mama Brickolini") instead of internal IDs.
Widen nav label min-width to 150px to prevent button shifting.
* Stabilize actor position when hat changes
Override centerAndScaleModel in ActorRenderer to exclude the hat
part from the bounding box calculation, so switching between hats
of different sizes no longer shifts the body/head position.
* Fetch assets from SI files via HTTP Range requests
Replace static animation, texture, and globe bitmap files with a
manifest-driven approach that extracts them directly from the game's
SI files at runtime using HTTP Range requests.
A new generate-manifest script scans SI files by MxCh objectId to
locate each asset's byte offset(s), verifies integrity via MD5, and
writes an asset-ranges.json manifest. The app consumes this manifest
to fetch assets on demand, including support for files split across
MxCh interleave boundaries.
Also removes unused constants (ActorLODIndex, animation keyframe
flag constants).
* Fetch character icons from SI files via HTTP Range requests
Replace static webp character icons with runtime extraction from
INFOMAIN.SI, extending the bitmap manifest to support multiple SI files.

* Fix actor editor animation and interaction bugs
Use mood (not sound+4*move) to select walking animation, matching
FUN_10063b90. Load secondary animation tier (speed 4.0 threshold)
which NPCs typically use in-game, producing the independent head/hat
movement. Fix switchSound wrap to 9 values, add switchColor click
remapping for claws/head/body, fix g_cycles case mismatches, add
morph key visibility support, and preserve root Y-translation for
vertical bounce while stripping horizontal movement.
* Add click animations to actor editor
Play a one-shot gesture animation when clicking an actor, matching the
in-game LegoEntity::ClickAnimation behavior (objectId = m_move + 10).
After the click animation finishes, the walking loop resumes. Adds the
4 click animations from SNDANIM.SI to the asset manifest and extends
ActorRenderer with queue-based click animation playback. Also fixes
treadmill XZ stripping for click animations where actor_01 is nested
under wrapper nodes.
* Add vehicle rendering to actor editor
Actors with personal vehicles (skateboard, motorcycles, bicycles) can
now be toggled between walking and vehicle mode via a button in the
actor navigation bar. Vehicle geometries are loaded from WDB world
models and rendered alongside the character with matching animations.
* Add click sound playback to actor editor
Plays the character's click sound (m_sound + 50) and, for Laura's
SwitchMood, an additional mood sound (m_mood + 66) from SNDANIM.SI,
matching the original game behavior. Sounds are fetched on demand,
decoded as WAV, and cached as AudioBuffers.
* Replace Range request asset loading with packed binary bundle
Extract save editor assets (animations, sounds, textures, bitmaps) into
a single save-editor.bin file at build time instead of fetching byte
ranges from ~550MB SI files at runtime. The bundle packs an embedded
JSON index and all fragment data into one file (~756KB), eliminating
Range request complexity and enabling proper Workbox precaching.
* Clean up actor editor branch: DRY, dead code, CSS
- Extract buildNodeToPartGroupMap() in ActorRenderer to deduplicate
map-building logic in loadAnimationForActor and playClickAnimation
- Refactor updateMissionScore() to use getMissionScoreOffset() instead
of duplicating offset calculation
- Remove unused ActorPartLabels export from actorConstants
- Make fetchBitmap module-private (only used by fetchBitmapAsURL)
- Merge duplicate .globe-btn CSS blocks in LightPositionEditor
* Add drag-to-orbit controls to vehicle and actor editors
Use Three.js OrbitControls in BaseRenderer for rotation-only orbiting
with damping. Vehicle editor auto-rotates and resets on part switch.
Actor editor uses orbit without auto-rotate (has skeletal animations).
Drag vs click detection uses pointermove threshold to avoid false
positives from autoRotate damping.
* Rebase WdbModelRenderer on BaseRenderer
Remove duplicated scene/camera/renderer/lighting setup, geometry
unpacking, animation loop, and dispose logic. Score cube gets orbit
controls and drag-vs-click detection for free.
* Add zoom, pan, and camera reset to 3D editors
Enable zoom (scroll/pinch) and pan (right-click/two-finger drag) on
all OrbitControls. Add resetView() to BaseRenderer that restores
initial camera state and auto-rotate via OrbitControls.saveState/reset.
Add reset camera button to EditorTooltip with mobile-friendly touch
targets and hover-only highlight to avoid sticky state on touch.
* Update changelog and fix sticky hover on touch devices
Add actor editor features, 3D orbit/zoom/pan controls, and camera
reset button to the February 2026 changelog. Wrap hover styles in
@media (hover: hover) for vehicle toggle and texture buttons.
* Update README with save editor setup, project structure, and Three.js
Add a Node.js script that sets up LEGO Island game assets via symlinks:
- Accepts source path interactively or via --path/-p flag
- Case-insensitive file matching for cross-platform compatibility
- Validates all required files before making changes
- Supports optional extra/ and textures/ folders
- Includes --force/-f flag to skip deletion confirmation
Updates README with new setup step and script documentation.
- Replace vanilla JS with Svelte 5 components
- Add Vite build system with Terser optimization
- Reorganize assets into src/ and public/ directories
- Update README with setup instructions
