AntiPattern

Lifecycle Cutoff on Scope

premature-lifecycle-teardown

Effect playback and input routing fail because game objects or input scopes are torn down early, cutting off particles/sounds and breaking routed ClientInput delivery; missed cleanup ordering prevents PostSetup effects and event handlers from completing.

MATCHESSolution

Use a cleanup function to clear the timeout, or simulate latency with Chrome DevTools throttling or MSW delay instead

MATCHESSolution

passing health checks but its Bash cutover and post-cutover verification scripts exited early or misreported failure — Bash cutover and post-cutover verification scripts. Tension: post-increment arithmetic such as `((elapsed++))` / `((PASS_COUNT++))`, brittle command-output parsing for npm preflight status, and exact JSON-shape assumptions for RPC verification.

MATCHESSolution

Using a `session-scoped` pytest fixture, for managing the event loop — which ensures the same event loop will be used. Outcome: loop.close().

MATCHESSolution

Change the engine async fixture from session scope to function scope (remove scope="session") so all async fixtures/tests run on the same event loop, preventing the cross-loop Future/Task error.

MATCHESSolution

bound it with a "progress ceiling" — a process emitting bytes but making NO semantic progress. Tension: a process emitting bytes but making NO semantic progress (livelock) would be shielded forever. Outcome: re-arms recovery after a long no-progress window even while bytes flow.

MATCHESSolution

Thread a second, lower-level liveness signal into the classifier — the timestamp of the last raw stdout byte from the child. Tension: Dead socket = no bytes = livenessAge grows = still aborts (correct). Alive-but-quiet = bytes flowing = livenessAge fresh = NOT aborted.

MATCHESSolution

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

MATCHESSolution

Stage 2 (startup). Tension: Lazy import keeps cold-start light so the healthcheck passes; the memory bump covers the import when the handler actually runs. Outcome: functions-framework can bind the port.

MATCHESSolution

case "CallbackRouteError": return { error: "Invalid credentials!" } — in my `login.ts` server action in the switch case clause. Tension: to return the correct errors. Outcome: bypass this error.

MATCHESSolution

track errors across the Flux — stopSignal = Sinks.one();. Tension: signal termination when the threshold is reached. Outcome: takeUntilOther(stopSignal.asMono()).

MATCHESSolution

Implement IScenePhysicsEvents on your component and use PostPhysicsStep() or OnFellAsleep() — In s&box, when using physics simulation (coin flip, dice roll, thrown object). Outcome: Add a timeout fallback in OnUpdate in case the body never sett.

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

Keep menu screens and in-game overlays in separate input modes. — Startup/customization menus can force Mouse.Visibility = Visible and keep pointer events enabled. Tension: Startup/customization menus can force Mouse.Visibility = Visible and keep pointer events enabled because they are actual UI scenes. Outcome: Fix pattern:.

MATCHESSolution

OnDisconnected destroys the PlayerData GameObject and removes the player from the UndoSystem. — GameManager implements INetworkListener. Tension: Clean up undo stacks. Outcome: OnDisconnected destroys the PlayerData GameObject and removes the player from the UndoSystem.

MATCHESSolution

call `body.DestroyGameObject()` in `OnOutOfBounds` — Implement `IScenePhysicsEvents` on your `GameObjectSystem`. Tension: prevents unbounded accumulation of out-of-world objects. Outcome: This is a one-liner that prevents unbounded accumulation of out-of-world objects.

MATCHESSolution

Capture a baseline in `ISceneLoadingEvents.OnLoad` — after `await Task.Yield()` to ensure all objects are spawned. Outcome: Use static fields to persist the baseline across `Game.ChangeScene()` calls.

MATCHESSolution

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

MATCHESSolution

Count by iterating only the player's list. Tension: pruning destroyed objects lazily during the count. Outcome: no separate cleanup pass needed.

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

Universal hook set for MCP behavioral activation. Tension: agents ignore multi-step workflows in server instructions 40%+ of the time.

MATCHESSolution

record that the side effect fired, check before firing again — awarding XP, delivering a notification, processing a queue item. Outcome: All three are instances of the same principle.

MATCHESSolution

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

MATCHESSolution

Implement `Component.ICollisionListener` on projectiles — Projectile.cs and TimedExplosive.cs. Tension: host only. Outcome: Trigger explosion via `[Rpc.Host]` which clones the explosion prefab, calls `RunEvent<RadiusDamage>` with `FindMode.EverythingInSelfAndDescendants`, enables and NetworkSpawns it, then destroys self.

MATCHESSolution

Set the renderer warmup tick count to zero — so first paint uses the live simulation state. Outcome: first paint uses the live simulation state.

MATCHESSolution

Resolved activity IDs to visible renderer IDs before queueing pulses — pulse-only animation. Outcome: paused the renderer when idle.

MATCHESSolution

Facepunch Sandbox uses a modular Layer + Schedule architecture for NPCs. Outcome: Layer system in d:\GitHubStuff\sandbox\code\Npcs\Layers\*.cs.

MATCHESSolution

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

MATCHESSolution

Record original scene objects on startup — CleanupSystem Component. Tension: Efficient batch destruction.

MATCHESSolution

Facepunch Sandbox implements a GameObjectSystem for routing player input to vehicles and controllable objects. — Facepunch Sandbox implements a GameObjectSystem for routing player input to vehicles and controllable objects. Tension: Seat-Based IPlayerControllable Routing. Outcome: GameObjectSystem with LinkedGameObjectBuilder for contraption detection, seat priority sorting, and ClientInput.PushScope.

MATCHESSolution

Fixes: for the lattice, thread filters into [REDACTED] props and add a highlight uniform, OR (if unspecified) drop the chip; for locked items, either wire onRecordFocus from the host or remove cursor:pointer/tabIndex.
