Extends the snapshot pattern to the three audio volume levels (system /
furni / trax) so volume-slider widgets on the React client can subscribe
to a single source of truth via useSyncExternalStore.
API additions on ISoundManager:
- systemVolume / furniVolume getters (parity with the existing
traxVolume getter)
- getVolumesSnapshot(): Readonly<ISoundVolumesSnapshot> with the same
lazy-frozen + invalidation-on-change semantics as the user/session
snapshots
- new ISoundVolumesSnapshot { system, furni, trax } interface
New event: NitroEventType.SOUND_VOLUMES_UPDATED. Dispatched only when
the incoming NitroSettingsEvent.SETTINGS_UPDATED actually changes one
of the three volumes (a no-op refresh stays quiet).
While in there, fixed a real bug: the previous implementation cached
`volumeFurniUpdated` / `volumeTraxUpdated` BEFORE writing the new
values, but read `castedEvent.volumeFurni` / `castedEvent.volumeTrax`
in their pre-division form — comparing percent (e.g. 75) against the
already-divided stored value (e.g. 0.75) — so the change check almost
always reported "updated" for a real settings push and never reported
"updated" if the percent matched the stored fraction by coincidence
(only 0/100 are stable). Updated check is now consistent (compare
fraction vs fraction) and also tracks systemVolume changes for the
new snapshot invalidation.
Extends the snapshot pattern to the room's user list. The React client
currently has many widgets each calling `getUserDataByIndex(idx)` in a
loop (chat, doorbell, room player list, infostand …) — every render
walks the underlying Map and rebuilds an array. With
`getRoomUserListSnapshot(): ReadonlyArray<IRoomUserData>` consumers can
memoize on the array reference and only rebuild when something actually
changed.
Invalidation fires on every state-changing path:
- updateUserData (add/replace)
- removeUserData (leave)
- updateFigure / updateName / updateMotto / updateNickIcon /
updateCustomization / updateBackground / updateAchievementScore /
updatePetLevel / updatePetBreedingStatus
The inner IRoomUserData objects keep their existing in-place mutation
semantics (deep-clone would be too expensive for 30+ avatars on every
single status push). Consumers should treat each entry as a
snapshot-at-time-of-read and not retain references across an
invalidation.
New event: NitroEventType.ROOM_USER_LIST_UPDATED. Interface and event
additions are backwards-compatible; no existing accessors changed.
Also tidied: `updatePetLevel` now uses the explicit `if(!userData)
return;` guard pattern matching the rest of the methods (was a one-line
inline conditional).
Extends the v2.1.0 React-friendly snapshot pattern (originally on
SessionDataManager / RoomSessionManager) to two more session-state
holders the React client reads frequently:
- IgnoredUsersManager.getIgnoredUsersSnapshot(): ReadonlyArray<string>
- GroupInformationManager.getGroupBadgesSnapshot(): ReadonlyMap<number, string>
Both follow the same shape: lazy-frozen snapshot, cached until the
underlying state mutates, then invalidated and a dispatched event lets
the React client rebuild via useSyncExternalStore.
Two new NitroEventType members carry the invalidation signal:
- IGNORED_USERS_UPDATED — dispatched by IgnoredUsersManager whenever
the list changes (initial load, add, remove, queue-truncate case 2).
- GROUP_BADGES_UPDATED — dispatched by GroupInformationManager only
when the incoming HabboGroupBadges payload contains at least one
new or changed mapping (no-op refresh stays quiet).
This lets the user-info popup, profile page, friend/guild filtering,
and any other consumer share a single read through useSyncExternalStore
instead of each subscribing to the underlying message events
independently.
API additions are interface-respecting and backwards-compatible — the
existing `isIgnored(name)` / `getGroupBadge(groupId)` accessors stay
untouched.
Cover every public method on the binary pair, plus the typical packet
shape (header + mixed payload) the composer/parser pipeline emits:
- byte / short / int round-trips, including signed-edge values
(int8 -1 from 0xFF, int16 / int32 boundaries)
- big-endian wire-order assertions on writeShort / writeInt (matches
Arcturus's DataInputStream)
- string round-trip with length prefix + bare (includeLength=false)
+ UTF-8 multibyte byte count + empty-string edge
- writeBytes for both number[] and ArrayBuffer payloads
- readBytes slice returns an independent reader whose position is
decoupled from the outer reader
- remaining() decrements correctly across mixed-size reads
- readFloat / readDouble decode IEEE-754 big-endian values
(the writer has no float/double counterparts — buffer is built via
DataView for these cases)
- writer position getter + explicit setter (caller-managed reposition)
- two independent writers concatenate cleanly into a single reader
Suite: 127/127 (was 104/104). typecheck clean.
Adds a 'Recent renderer changes' section to CLAUDE.md covering all
the non-v2.1.0 work that landed during the React 19 modernization
round:
- RoomEnterComposer optional spawnX/spawnY (matches Arcturus'
RequestRoomLoadEvent optional tail).
- RoomSettingsData.allowUnderpass field + parser tail-int + composer
optional arg (Arcturus already emits the int).
- Dropped dead sendWhisperGroupMessage / ChatWhisperGroupComposer.
- TS 5.7+ ArrayBuffer drift handling and Pixi v8 narrows
(FurnitureBadgeDisplayVisualization signature realignment,
WebGLRenderer cast in ExtendedSprite, Filter[] union in AvatarImage,
ImageLike cast in TextureUtils, NitroConfig Window-decl unification,
empty-tuple composers).
- PetBreedingMessageParser bytesAvailable bool-vs-number bug fix.
Also adds two gotchas: 'bytesAvailable is a boolean' (was hit by
PetBreeding) and 'composer getMessageArray return type must match
the type argument' (was hit by both Wired*RequestComposer).
Arcturus' RoomSettingsComposer appends an extra int at the end of the
payload — room.isAllowUnderpass() ? 1 : 0 — and RoomSettingsSaveEvent
optionally reads back a boolean at the end (if bytesAvailable > 0).
The renderer side never modeled this trailing field, so the client
couldn't surface or persist it.
- RoomSettingsData: add _allowUnderpass field + getter/setter +
propagation through the .from() copy.
- RoomSettingsDataParser: read one trailing int after the moderation
settings, guarded by 'if(wrapper.bytesAvailable)' so older servers
that don't emit it keep parsing cleanly.
- SaveRoomSettingsComposer: optional trailing allowUnderpass arg. The
server's optional-read guard tolerates 24-arg or 25-arg payloads, so
callers that don't care about the field still send the legacy shape.
Cross-repo reference points:
- Arcturus emit side: Emulator/src/main/java/com/eu/habbo/messages/
outgoing/rooms/RoomSettingsComposer.java line 55.
- Arcturus read side: Emulator/src/main/java/com/eu/habbo/messages/
incoming/rooms/RoomSettingsSaveEvent.java lines 133-135.
Net client tsgo error count: 3 -> 0 on the NavigatorRoomSettings cluster.
Two tsgo nits that propagate to the client when the renderer is linked
in:
- packages/utils/src/NitroConfig.ts declared
'NitroConfig?: { [index: string]: any }' on Window, but Nitro-V3
declares 'NitroConfig?: Record<string, unknown>' in its
react-app-env.d.ts. The two declaration-merging fragments must
match — switching the renderer side to Record<string, unknown>
unifies them.
- packages/assets/src/AssetManager.ts: 'import.meta.glob(...)' is
augmented as Record<string, string> in the client's typedef, so
'mod.default ?? mod' (defensive handling of either string or
{ default: string }) failed because mod is typed string. Cast
inline: '((mod as { default?: string }).default ?? mod)'.
Renderer tsgo error count: 3 -> 0.
- SocketConnection.processMessage() did 'new events[0].parserClass()'
where parserClass is typed as 'Function' on IMessageEvent (no
construct signature). Cast to 'new () => IMessageParser' at the
call site so the spawned instance is type-correct downstream.
- RoomChatHandler dispatched RoomSessionChatEvent with the args in
the wrong order: '[]' (intended as the 'links' array) was landing
in the 'chatColours' string slot. Swap to '"", []' so links go
to position 8 and chatColours stays a string.
Four sites where Pixi v8's stricter typing tripped tsgo:
- AvatarImage: container.filters is typed as 'readonly Filter[] | null'
in v8 (no longer a single-Filter union). The old fallback branch
'else container.filters = [container.filters, …]' tried to treat a
readonly array as a single Filter; collapsed to the array-spread
path which now covers both undefined and non-empty cases. Added
Filter to the pixi.js import.
- FurnitureBadgeDisplayVisualization.updateSprite() had a 4-arg
override (sprite, asset, scale, layerId) of the parent's 2-arg
signature (scale, layerId). The sprite/asset were never used from
the parameters — the body only mutated 'sprite'. Refactored to
fetch the sprite via this.getSprite(layerId) inside the override
body so the signature matches the base.
- ExtendedSprite: 'renderer.gl' / 'glRenderTarget.resolveTargetFramebuffer'
exist only on WebGLRenderer / GlRenderTarget (not the WebGPU
variants). The runtime check 'renderer.type === RendererType.WEBGL'
guarantees this; cast at the boundary to satisfy the typechecker.
- TextureUtils.generateImage: Pixi v8's Extractor.image() returns the
union ImageLike (HTMLCanvasElement | HTMLImageElement); the public
signature promises HTMLImageElement. Cast at return — the Pixi
default backend returns HTMLImageElement here.
Arcturus' RequestRoomLoadEvent reads the two extra ints only when
the inbound packet has 8+ bytes remaining after roomId+password, so
the renderer can send 2-arg or 4-arg payloads against the same
header. The client already calls 'new RoomEnterComposer(roomId,
password, spawnX, spawnY)' in two places inside RoomSession /
RoomSessionManager (the reconnect/respawn flow) — the composer
signature is what was lagging behind.
Server-side reference:
Arcturus-Morningstar-Extended/Emulator/src/main/java/com/eu/habbo/
messages/incoming/rooms/RequestRoomLoadEvent.java
bytesAvailable is a boolean (IMessageDataWrapper.bytesAvailable: boolean,
returns 'there is at least one byte left'); the parser was doing
'wrapper.bytesAvailable < 12' as if it were a count, which both
mis-compares boolean to number and short-circuits incorrectly when
exactly 11 bytes remain.
Align with every other parser in the codebase: 'if(!wrapper ||
!wrapper.bytesAvailable) return false;'. The downstream readInt
calls already throw on truncated packets so the explicit length
check was load-bearing only against malformed inputs that wouldn't
parse anyway.
WiredRoomSettingsRequestComposer and WiredUserVariablesRequestComposer
declared 'implements IMessageComposer<ConstructorParameters<typeof Self>>'
but neither defines a constructor, so ConstructorParameters resolved
to 'any[]' and getMessageArray() returning [] (any[]) failed the
narrower base-type signature () => [].
Both composers send zero payload; type as IMessageComposer<[]>
directly + annotate the return type.
IRoomSession.sendWhisperGroupMessage(userId) was declared in the
interface and implemented in RoomSession by sending 'new
ChatWhisperGroupComposer(userId)' — but no such composer class
exists in the renderer (the file was never created). The only
whisper composer is RoomUnitChatWhisperComposer, which takes
(recipientName, message, styleId), not a userId.
No client call site references sendWhisperGroupMessage (grep across
Nitro-V3/src returned zero hits). Removing the dead interface method
+ broken impl is safer than inventing a ChatWhisperGroupComposer
class with no server-side handler.
TypeScript 5.7 split ArrayBuffer / SharedArrayBuffer at the type level
(ArrayBuffer now exposes resizable/transfer/detached etc; SharedArrayBuffer
doesn't), and parametrized the typed-array constructors so plain
Uint8Array became Uint8Array<ArrayBufferLike>.
The renderer never uses SharedArrayBuffer, so this is type-level only —
narrowing back to ArrayBuffer at the boundaries:
- BinaryReader.readBytes() / .toArrayBuffer() return the underlying
DataView buffer; cast to ArrayBuffer.
- BinaryWriter.getBuffer() same shape.
- WsSessionCrypto.randomNonce() now returns Uint8Array<ArrayBuffer>
(it's always backed by a plain ArrayBuffer); aesGcmEncrypt/Decrypt
nonce parameter retyped accordingly so SubtleCrypto.encrypt accepts
it as BufferSource.
- ArrayBufferToBase64 now accepts Uint8Array | ArrayBufferLike directly
(pako/inflate hands back Uint8Array<ArrayBuffer> which the old
ArrayBuffer-only signature rejected).
The IRoomSession interface was missing three things that have always
existed on the RoomSession implementation:
- `password: string` — the room session's join password (used by the
reconnect flow in RoomSessionManager).
- `sendBackgroundMessage(backgroundImage, backgroundStand, backgroundOverlay, backgroundCard?)`
— sends the profile-background composer (used by the React client's
BackgroundsView).
Plus a signature relaxation:
- `sendChatMessage` / `sendShoutMessage` `chatColour` is now optional.
The implementation already accepted `undefined` (the composer forwards
it through), and every historical call site in the React client passes
only 2 args — making the 3rd optional simply types reality.
Net renderer typecheck: 26 → 23.
The change also drops 7 errors on the consumer side
(see ../Nitro-V3 typecheck after the workspace link picks this up).
CLAUDE.md gotchas updated to reflect the new interface contract.
`AssetManager.loadRoomImages()` and friends use `import.meta.glob('./assets/...', { eager: true })`
to bundle PNG assets via Vite, but TypeScript doesn't see `glob` on
ImportMeta without pulling `vite/client` — which we avoid here so the
React client (which has its own asset declarations) keeps full control.
src/globals.d.ts adds just the `glob` signature, typed for the eager
image case (`Record<string, { default: string }>`). The call sites'
existing `mod.default ?? mod` narrowing still works.
Net renderer typecheck: 29 → 26 (-3 errors).
Each workspace package was still pinning `typescript: ~5.5.x` or
`~5.8.2` in its own devDependencies even though the root bumped to 6.0.3
in 60b1143. The pins were dead (yarn 1 hoists from root) but they're
misleading when reading a single package.json. Bring them all to
`^6.0.3` to match the root.
Other:
- @thumbmarkjs/thumbmarkjs 1.8.1 → 1.9.0 (root + communication package)
- yarn.lock regenerated from a clean install (vitest 4 hoisting was
flaking on the patch vite bump; reverted vite to ^8.0.10)
Adds CLAUDE.md at the repo root: short project context for future
sessions — stack, the 12-workspace layout, the React-friendly v2.1.0
additions (`subscribe()`, `subscribeMessage()`, snapshot getters), build
scripts, and known gotchas (`SessionDataManager.getUserData` does NOT
exist; sendChat* expects 3 args; dispatchEvent is sync).
- typescript: ~5.8.2 → ^6.0.3 (matches Nitro-V3 client)
- adds @typescript/native-preview (tsgo) as TypeScript 7 preview
- new `compile:fast` script using tsgo (~7× faster: 2.5s vs 17.6s)
- tsconfig cleanup ahead of TypeScript 7 deprecations:
- removed `baseUrl` (unused: no `paths` mappings on this project)
- removed `downlevelIteration` (target ES2022 makes it a no-op)
- `moduleResolution`: "Node" → "bundler" (vite consumes the renderer)
Compile errors: 28 → 29. Net +1 because TS 6's tightened lib types flag
two pre-existing crypto calls (WsSessionCrypto.ts:43,48) and resolves one
prior false positive. All errors are in pre-existing code, unrelated to
the new event/snapshot APIs from 791b8ad.
