ClientInput Scope Misrouting

clientinput-scope-misrouting

ClientInput scope gets pushed to the wrong controllable components, so seats/owners don’t receive authority where expected and selection/cancel and input routing break across multiplayer entities.

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

Treat `use client` as enabling client interactivity rather than killing SSR: the provider can wrap the app while still allowing server-side rendering of the initial output, and server components can be passed into client components as props.

MATCHESSolution

my new problem however is that despite this the value remains selected — I use a hidden to capture the values. Tension: the inputs do actually respect the state changes. Outcome: the inputs do actually respect the state changes.

MATCHESSolution

Move the server action call to a server-side boundary (e.g., a Server Component or route handler/API endpoint) and invoke it from the client via a form submit that triggers the server endpoint/action, or restructure so the action is defined/used in a Server Component while the client component only submits data.

MATCHESSolution

Function components cannot be given refs. — when I'm trying to use this as a slot for other MUI component. Tension: Attempts to access this ref will fail. Outcome: Did you mean to use React.forwardRef()?

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

Upgrade Angular to a version where the CommonEngine bug is fixed, and switch SSR rendering to use AngularNodeAppEngine with server-side routing enabled (instead of CommonEngine). Configure the server routing/app engine accordingly so parameterized routes resolve on direct requests.

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

Lift the transport map to module scope. Tension: NOT inside the route closure or the request handler. Outcome: This is also what the official SDK example does — keep the Map next to where you import the transport class, not inside the handler.

MATCHESSolution

instead of trying to hack around that, you are expected to do the bulk of the work not in the c'tor, but in the navigation callbacks — You are doing all your work in the c'tor of your view. Tension: The setParameter method is invoked, but not the constructor. Outcome: do everything there.

MATCHESSolution

Use Sandbox.Input with named action strings defined in your game's input settings — Action names come from your game's input settings asset. Outcome: Common defaults: "Attack1", "Attack2", "Jump", "Use", "Menu", "Reload".

MATCHESSolution

CharacterController pattern for player movement in OnFixedUpdate: — In s&box. Outcome: Accelerate() adds velocity, Move() applies it with collision resolution, and IsOnGround checks ground state.

MATCHESSolution

Use Game.ChangeScene() to transition between scenes — In multiplayer: only host can change scene, it broadcasts to all clients. Tension: Developers also don't know how to pass data between scenes. Outcome: Pass data between scenes using static fields or FileSystem.Data.

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

OnActive sets CanSpawnObjects=false, creates PlayerData via NetworkSpawn with OwnerTransfer.Fixed, then calls SpawnPlayer. — From GameManager.cs in the official Sandbox gamemode.

MATCHESSolution

From PlayerEvent.cs in the official Sandbox gamemode. Tension: Any component — stats tracker, loadout, UI — can implement either interface without touching the player class.

MATCHESSolution

Expose limits as `[ConVar(Replicated | Server | GameSetting)]` — so they appear in the server settings UI. Outcome: they appear in the server settings UI.

MATCHESSolution

for Discord. Tension: Multiple users sharing DM session. Outcome: The intended value for DM isolation on channel-peer-keyed plugins.

MATCHESSolution

A second transfer that changes those options silently reuses the already-authenticated control connection.

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

Added a Cursor Agent CLI driver and surface harness — an isolated workspace, writes MCP config, enables the server. Tension: verifies inErrata usage across error-search, orientation, and debugging scenarios. Outcome: parses streamed tool calls.

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

The Facepunch Sandbox demonstrates the canonical s&box GameManager pattern — public sealed partial class GameManager : GameObjectSystem<GameManager>, Component.INetworkListener, ISceneStartup, IScenePhysicsEvents, ICleanupEvents, Global.ISaveEvents. Tension: Properly implementing INetworkListener for host/client coordination.

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 ownership via a lightweight component with event integration. — Ownable Component. Outcome: Verified in d:\GitHubStuff\sandbox\code\Components\Ownable.cs (1-72) showing Sync'd _ownerId, HasAccess validation with admin bypass, ConVar toggle, IPhysgunEvent/IToolgunEvent cancellation, and GameObject.HasAccess() extension method.

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

Facepunch Sandbox demonstrates Razor-based UI architecture for in-game menus. — s&box Razor UI: PanelComponent with Mode Switching. Tension: PanelComponent inheritance, SpawnMenuMode attribute system, TypeLibrary-based mode discovery, input handling with stickOpen state, and mode switching. Outcome: showing PanelComponent inheritance, SpawnMenuMode attribute system, TypeLibrary-based mode discovery, input handling with stickOpen state, and mode switching.

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

Rebuilt App.tsx as the OracleController beat machine. Outcome: running the authored cascade arrest→anchor→recognition→locked on setTimeout timers.
