Local Effects Bypass Sync

local-effects-bypass-sync

Local-only gameplay/visual effects (camera noise, world-space shake, recoil interpolation) run outside the network or physics event pipeline, so remote clients or edge-case physics states miss updates, producing desynced visuals and timing glitches.

MATCHESSolution

you can use Zustand getters and optimistic update — multiple or rapid clicks could actually cause the updates to be executed but out of order. Tension: no optimistic update so u see that delay (lag) you said about.

MATCHESSolution

Leverage React 18's `useSyncExternalStore` — ensure consistent state between SSR and CSR. Tension: client-side state doesn't sync properly with the server-rendered state. Outcome: to ensure consistent state between SSR and CSR.

MATCHESSolution

Handle server→client synchronization inside the socket event handler (or a centralized layer like middleware) to keep updates consistent and avoid lifecycle coupling. Use component-level listeners only for client→server events where it’s appropriate, ensuring callbacks are registered/unregistered correctly.

MATCHESSolution

handle a scenario when the code is fine but backend went offline — prefetching data with usePrefetchQuery. Tension: prefetch works.

MATCHESSolution

Use a global or local state to control the DnD UI, then sync that state with React Query data and update the server on drag end

MATCHESSolution

useEffect(). Tension: not if it gets re-fetched in the background while the user is editing the form. Outcome: without it?

MATCHESSolution

Configure `.syncpackrc` to handle only the special case (local monorepo packages/workspace protocol), e.g., add a version group that pins `$LOCAL` dependencies to `workspace:*` for `packages: ['**']`. Then rely on Syncpack’s default behavior to discover and sync the versions of shared dependencies like react/react-dom and related @types across apps.

MATCHESSolution

If true, staleness checks for cached data will be bypassed, but missing data will be requested from the server. Tension: Default: false. Outcome: To force full offline mode, use --offline.

MATCHESSolution

fail-LOUD when the local model can't load — the local model can't load. Tension: never silently fall back to a cheaper vectorizer like a hashing trick. Outcome: that swaps the geometry under the index.

MATCHESSolution

depending on your latency budget. Outcome: Same idea, but the state lives outside the process boundary.

MATCHESSolution

try looking at the DesktopLauncher.java and see if there's a config parameter that might affect the framerate - such as vsync. — DesktopLauncher.java. Tension: some subtle stuttering every now often. Outcome: try removing any fps cap to see how it performs unrestricted.

MATCHESSolution

Choose [Sync] flags based on who owns the value and how it changes — s&box multiplayer.

MATCHESSolution

Use BeamEffect for animated line visuals (lasers, tracers, lightning): — s&box.

MATCHESSolution

Apply synchronously (no download for missing items) — container.Apply(renderer);. Outcome: Apply synchronously (no download for missing items).

MATCHESSolution

Add TemporaryEffect to GameObjects that should auto-destroy after effects finish — In the scene editor: add TemporaryEffect component to your effect prefab. Outcome: BecomeOrphan = true: if parent is destroyed, detach and finish playing.

MATCHESSolution

after mutating the property. Tension: Per-component refresh is broken. Outcome: always refresh the whole GameObject.

MATCHESSolution

CollectSyncState() iterates all components, finds [Sync] properties without [Property], serializes them to JSON — in SaveSystem.cs. Tension: Use JSON serialization first, with a ByteStream/BytePack fallback for types that don't serialize cleanly to JSON. Outcome: RestoreSyncState() is called before RestoreNetworkOwnership() in the Load path.

MATCHESSolution

Bans are persisted via LocalData (host-side JSON) — LocalData (host-side JSON). Tension: bans in memory only (lost on restart). Outcome: Persist bans using `LocalData.Get/Set` keyed by SteamId.

MATCHESSolution

Implement `ICameraSetup.PostSetup` for world-space shake. — From EnvironmentShake.cs and Notices.cs. Tension: Compute distance falloff via `DistanceCurve.EvaluateDelta((distance/MaxDistance).Clamp(0,1))`. Outcome: Multiply by `GamePreferences.Screenshake` to respect user settings. Use `Noise.Perlin(Time.Now * Rate, offset)` with different offsets per axis (0, 830, 340) for natural-looking shake.

MATCHESSolution

Implement `Local.IPlayerEvents.OnLand(float distance, Vector3 velocity)`. — From PlayerFallDamage.cs. Tension: Call `[Rpc.Broadcast]` with host guard to apply damage on host. Outcome: Play fall sound via `[Rpc.Owner]` so only the owning client hears it.

MATCHESSolution

Two approaches for runtime particle effects in s&box: — runtime particle effects in s&box.

MATCHESSolution

Implement both `ITriggerListener` and `ICollisionListener` on pickup components — In `[Rpc.Broadcast]` sound effects. Tension: Without a `IsDestroyed` guard, both can fire simultaneously causing double-pickup. Outcome: set `snd.SpacialBlend = 0` when `player.IsLocalPlayer` for 2D sound, leave default (3D) for others.

MATCHESSolution

Camera noise uses the CameraNoise.Recoil class — local only. Tension: instantiated locally, not networked. Outcome: new CameraNoise.Recoil(strength, frequency).

MATCHESSolution

ShootEffects is [Rpc.Broadcast] — muzzle flash/impact effects. Tension: for muzzle flash/impact effects. Outcome: [Rpc.Broadcast].

MATCHESSolution

Cache in OnAwake — Key s&box performance patterns from the optimizer skill:. Tension: GetComponent every frame. Outcome: Physics work in OnFixedUpdate.

MATCHESSolution

the snapshot was set to a partial dataset (nodes but zero edges) — after the stream actually finished and the full state arrived. Tension: an early-return in the snapshot effect prevented the snapshot from updating. Outcome: the full state arrived.

MATCHESSolution

Build the graph from edge candidates first — the web proxy was forwarding the old backend stream. Tension: a retry needed to be robust even when the backend deployment lagged. Outcome: over-fetches graph candidates from the backend, drops disallowed instance/evidence nodes, maps canonical edge endpoints to concrete type:id renderer ids, assigns connected-component communities, prunes isolated nodes, and trims back to the requested render budget.

MATCHESSolution

Facepunch Sandbox demonstrates a clean dual-scope event architecture using `Local` and `Global` static classes. Tension: Difficulty implementing cancellable events.

MATCHESSolution

Facepunch Sandbox implements a GameObjectSystem-based ban system with INetworkListener. — Load from LocalData on startup. Tension: INetworkListener - blocks at connection time. Outcome: Reject con.

MATCHESSolution

needsUpdate was being set to true. Tension: Instance matrix updates and shader uniform pushes appear to have no effect. Outcome: The animation loop was confirmed running (frame counter incremented normally in Firefox).
