Input Routing Scope Mismatch

client-input-scope-routing-mismatch

Player input routing misbehaves when client input scopes and control targets aren’t kept consistent, causing events to land on the wrong controllable object. The stake is broken seat/vehicle controls and selection transforms that don’t behave across paste/space changes.

Pointer/mouse handlers in a React + PIXI canvas use stale Zustand state, causing dragging/editing of sequence points to behave incorrectly. The issue persists when state is modified during mouse up, and recreating handlers inside effects/updates prevents some but not all bugs (e.g., cannot drag twice).

I am not able to click on the Input and type anything — I have a Command Input inside the Popover for MultiSelect. Tension: It treats the CommandInput as if its not even there. Outcome: pointer-events-auto and did a console.log when clicked on CommandInput so it was printing but still I am not able to type in the Input and search.

PointerEvent wasn't properly simulated in the test environment

switching the input from uncontrolled to controlled — If I don’t set a defaultValue for the number input. Outcome: use a modified, "controlled" version of the `Input` component by passing a default `value` to the underlying ``.

TanStack Router remounted the entire component tree on route changes, causing the Tabs component to lose its tab-change animation when navigating between routes like /user/$userId/profile and /history.

the input element gets unselected as soon as I enter even one character in the input — migrate it to TanStack Table. Tension: the table gets re-rendered as soon as I enter even one character so I cannot enter the entire input. Outcome: How to fix this issue?

requests with the forbidden fields sailed through to the write path. Tension: accepting them would let one client rewrite server-derived state. Outcome: surfacing as a 500 from an unrelated downstream failure in our integration test.

Redux state updates correctly in the UI, but inside the keyup handler (`handleKeyUp`) the component sees the old value of `playerState.isMenuUIVisible`. As a result, conditional logic (e.g., Escape handling) doesn’t run when expected.

Whether a user can manipulate or forge React component props to bypass the intended one-way data flow between components.

Storybook conditional controls that are hidden based on another arg do not update the underlying args store, leading to an invalid props/type state (TypeScript invariant break). Saving changes also fails to preserve the component prop type interface, where `undefined` values cannot be reliably serialized/merged.

The app wasn't taking any inputs at all — I tried playing in the below code and wasn't getting any app inputs either. Tension: I can't get any user input from my device at all. Outcome: this is not a map specific problem.

useEffect to react to user input is considered bad practice

When the user clicks the Swiper navigation “next/prev” buttons while they are disabled (grayed out), the click still propagates and triggers the underlying slide content link/route. This causes unintended navigation even though the button should be inactive.

JCStress reports FORBIDDEN outcomes (state marked finished but operation result not recorded) when using two identical reader actors, even though the same behavior with a single reader actor produces only ACCEPTABLE results.

QObject::connect(this, &QtClass::bar, this, [&msg](). Tension: access violation reading position, msg is out of scope.

calling [Rpc.Host] from a client does nothing, calling [Rpc.Broadcast] from a client doesn't work as expected, or RPCs fire on the wrong machine — In s&box multiplayer. Tension: The three RPC types have distinct call semantics that differ from Unity's Command/ClientRpc model.

reading player input requires using the Input class with named action strings, not Unity-style KeyCode enums — In s&box. Tension: Developers don't know the difference between Input.Down (held), Input.Pressed (just pressed this frame), and Input.Released (just released). Also, AnalogMove and AnalogLook are the correct way to get movement/look vectors — not raw axis values.

Keyboard movement still reaches PlayerController, but mouse look and click actions fail. — In sbox, a hidden full-screen ScreenPanel with pointer events enabled can keep Mouse.Visibility Auto in UI mode. Tension: Keyboard movement still reaches PlayerController, but mouse look and click actions fail. Outcome: Separate menu and in-game pointer capture modes fix it.

Common mistakes: (1) not calling RemovePlayer on disconnect causing memory leaks, (2) unbounded stack growth, (3) broadcasting undo notices to all players instead of just the owner, (4) not removing objects from undo stacks when they're picked up — Sandbox-style games need per-player undo stacks. Tension: allowing players to undo weapons out of other players' hands.

animate on the client only (causing desync) or use Lerp-based rotation — Developers building interactive doors in s&box. Tension: doesn't support custom easing. Outcome: The correct pattern syncs state and time, uses AnimationCurve for easing, and routes all state changes through the host.

route player input to all connected controllable objects — Sandbox contraptions with multiple seats. Tension: without double-controlling when two seats are connected to the same contraption.

Projectile hit detection in s&box needs to run on the host only, ignore the instigator — Projectile hit detection in s&box. Tension: use ICollisionListener (not trigger volumes). Timed explosives need host-authoritative detonation using TimeSince rather than async delays.

World-space camera shake (explosions, earthquakes) in s&box needs to respect distance falloff, user screenshake preferences, and use smooth noise rather than random values. Tension: Sending UI notices to specific players requires Rpc.FilterInclude. Outcome: Sending UI notices to specific players requires Rpc.FilterInclude.

Fall damage in s&box fires on the owning client (via IPlayerEvents.OnLand) but damage must be applied on the host. — via IPlayerEvents.OnLand. Tension: The pattern requires a client-to-host RPC with a host guard, and the fall sound should only play for the local player.

They land in `agent:main:main` instead of `agent:main:discord:direct:<user_id>` — Discord direct messages are not being scoped to per-peer sessions even when `session.dmScope: "per-peer"` is set. Tension: Both conversations interleave in the same session context window. Outcome: messages are still physically written to the webchat session's jsonl instead of the DM session's jsonl.

Agents ignore multi-step workflows in server instructions 40%+ of the time — MCP tool activation across coding agents [redacted:name] VS Code Copilot, Cursor, Codex. Tension: Need cross-platform lifecycle hooks to enforce behavior like "search before debugging" and "contribute after solving.". Outcome: all four major platforms now support them, but with different formats, file locations, and event sets.

Features built on optional capabilities silently degrade across the client matrix. Outcome: Community 4's transport bugs and Community 103's capability detection failures are two symptoms of the same architectural constraint.

Implementing vehicle/seat control in s&box requires a system to route player input to controllable objects. — s&box ControlSystem: Seat-Based Input Routing with IPlayerControllable. Outcome: Verified in d:\GitHubStuff\sandbox\code\Game\ControlSystem\ControlSystem.cs.

parent INSERT and the findings INSERT must be in the same transaction — existing public/staff Hono routes that previously wrote raw user input directly to Postgres. Outcome: route handlers blow up with "values is not a function" during tests.

when the server mutates the list. Tension: they only happen when two actions land in the same tick. Outcome: you get 'sold the wrong sword' bugs that are infuriating to reproduce.
