From 4a1c594887c4018cea2cc4a1b1aec8f0ae721b34 Mon Sep 17 00:00:00 2001 From: Erik Date: Wed, 13 May 2026 17:28:18 +0200 Subject: [PATCH 01/14] docs(B.4b): design spec for outbound Use handler wiring Phase B.4b closes the M1-blocker discovered during the L.2g slice 1 visual test: the input dispatcher fires SelectDblLeft on click but GameWindow.OnInputAction has no case for any Select* / UseSelected action, so clicks silently die. Spec creates the minimum new structure to close the gap: - New static helper WorldPicker (BuildRay + Pick over WorldEntities) - Rename _selectedTargetGuid -> _selectedGuid on GameWindow (unifies combat + interaction selection per retail's single-target model) - Three switch cases (SelectLeft, SelectDblLeft, UseSelected) Two further L.2g handoff inaccuracies surfaced during exploration: WorldPicker and SelectionState do NOT exist in src/ (handoff and ISSUES #57 both claimed they did). BuildPickUp also doesn't exist; only BuildUse / BuildUseWithTarget / BuildTeleToLifestone are present. Spec accounts for the actual state and defers BuildPickUp + SelectionState class extraction. Visual verification scenario reuses the L.2g slice 1 reproducibility recipe: one Holtburg inn doorway log captures both L.2g + B.4b.

The +input dispatcher correctly fires `SelectDblLeft` on every double-left- +click — the diagnostic `[input] SelectDblLeft Press` line shows in the +log — but `GameWindow.OnInputAction`'s switch has zero `case +InputAction.SelectLeft / SelectDblLeft / UseSelected` branches. +Nothing downstream listens.

No new guard needed. +- **No live session / not in world**: `SendUse` short-circuits early. + Toast "Not in world" for debug visibility. Picker still runs (cheap; + fine to leave selection state updated even offline). +- **`UseSelected` with no current selection**: toast "Nothing + selected". No network send. +- **Selected entity despawns between select and use**: `BuildUse` + still sends the cached guid. ACE replies with `UseDone` carrying + `WeenieError.InvalidObject` (a non-zero error code). That error + already flows into the chat-log channel via the existing + `GameEventType.UseDone` handler; no new code needed. +- **Ray construction degenerate**: if `direction.LengthSquared() < eps`, + treat as no-hit and return null from `Pick`. Defensive — should + never trigger for sane view/proj matrices. +- **Entity at exactly `_selectedGuid` despawns silently while + selected** (e.g. NPC walks out of streaming range): `_selectedGuid` + becomes a stale reference.

The picker doesn't care about player position. | +| **State value `0x4` vs `0x14`** — L.2g slice-1 review flagged that `CollisionExemption.ShouldSkip` requires both `ETHEREAL (0x4)` AND `IGNORE_COLLISIONS (0x10)`. If ACE sends only `0x4`, the exemption won't fire. | Settled by the same visual test's `[setstate]` log line. If `0x4` only, file a tiny L.2g slice 1b to widen the check; that's a one-line edit and out of B.4b scope. | +| **`_lastMouseX/Y` at click time vs. dispatcher-fire time** — if there's a frame of latency between Silk's mouse-down event and the dispatcher fire, the mouse may have moved. | Silk fires mouse-down synchronously; `_lastMouseX/Y` are updated on every move, so they hold the click position at the moment the dispatcher fires. Verified by reading the existing `OnMouseDown` path. Low risk. | +| **Entity not in `_entitiesByServerGuid` despite being visible** — e.g. dat-hydrated EnvCell statics have `ServerGuid=0` and won't be pickable | Acceptable for B.4b. Doors and NPCs in Holtburg are server-spawned with non-zero `ServerGuid`. Dat-hydrated statics (fireplaces, decorations) aren't meant to be Use-able. | + +### Open question after slice ships (L.2g slice 1b) + +The L.2g slice-1 final-review "Important note" — does ACE's +`PhysicsObj.cs:787-791` set both `ETHEREAL_PS (0x4)` AND +`IGNORE_COLLISIONS_PS (0x10)` simultaneously when doors open, or only +ETHEREAL? B.4b's visual test settles this. If the hex shows `0x4` +alone, file L.2g slice 1b to either widen `CollisionExemption.ShouldSkip` +to `((state & ETHEREAL_PS) != 0)` alone, or set both bits in +`UpdatePhysicsState`. Decision deferred until evidence lands. + +--- + +## Reproducibility + +Same launch recipe as L.2g slice 1 (above).

The single t = -b - sqrt(d) intersection skipped entities whose 5m bounding sphere contained the ray origin. Realistic at point-blank range — if the player stands within ~5m of a door, the near-plane sits inside the door's bounding sphere and the door becomes unpickable. Standard fix: when t_near < 0 fall through to t_far = -b + sqrt(d) (the sphere exit point). 2. The discriminant formula assumes |direction| = 1. BuildRay currently normalizes so the assumption holds at the wire, but the contract wasn't documented. Added an explicit note. New test Pick_RayOriginInsideEntitySphere_StillReturnsServerGuid covers the inside-sphere case. Suite: 9/9 WorldPicker tests pass.

Adds three OnInputAction switch cases (SelectLeft, SelectDblLeft, UseSelected) and three private helpers (PickAndStoreSelection, UseCurrentSelection, SendUse). Single-click selects but does not Use; double-click selects + Uses; R hotkey sends Use on the existing _selectedGuid. ImGui mouse-capture filtering already happens in InputDispatcher — no new guard needed. Diagnostic lines emitted for log grep: [B.4b] pick guid=0x{guid:X8} name={label} [B.4b] use guid=0x{guid:X8} seq={seq} Also adds a one-line doc comment on _selectedGuid clarifying its dual-purpose role (combat Q-cycle + interaction click), per the Task 3 review. Build green; tests 1046/1054 (8 pre-existing-baseline fails unchanged). Switch-case behavior verified at runtime via the Holtburg inn doorway visual test (per spec §Testing → Runtime verification).

OnMouseDown was only looking up Press and Hold activations — DoubleClick bindings in KeyBindings.cs were effectively dead code. Adds 500ms-threshold double-click detection: tracks last-mouse-down button + Environment.TickCount64 timestamp; a same-button press within the threshold additionally fires ActivationType.DoubleClick for the matching binding (Press still fires normally for the second click). Clears the pair-state after firing so a triple-click doesn't produce a second DoubleClick. Tests cover same-button within threshold, beyond threshold (no fire), different-button (no fire), and triple-click (fresh pair required).

The L.2g pipeline correctly mutates ShadowObjectRegistry with the new state, but CollisionExemption.ShouldSkip required both bits and the door stayed solid. Retail (acclient_2013_pseudo_c.txt:276782) wraps FindObjCollisions in `if NOT (state & ETHEREAL && state & IGNORE_COLLISIONS)`. ETHEREAL alone takes a different retail path at line 276795 that sets sphere_path.obstruction_ethereal = 1 and lets downstream movement allow passage despite the contact. We haven't ported that downstream path yet. Pragmatic shortcut: widen the early-out to ETHEREAL alone so doors become passable when ACE flips the bit.

The fix widens the gate to + `if (activation != Press && activation != DoubleClick) return;`. + The switch now reaches the `SelectDblLeft` case. + +4. **Ray construction** — `WorldPicker.BuildRay(mousePos, viewport, viewMatrix, projMatrix)` + unprojects the cursor pixel into a world-space ray origin + direction, + using standard NDC→view→world unprojection. Numerically: the mouse pixel + is mapped to `[-1,+1]` NDC, transformed through `inverse(proj)` to get + a view-space direction, then through `inverse(view)` for world-space. + +5. **Entity pick** — `WorldPicker.Pick(ray, entities, maxDist=50m)` iterates + all entities in `_gpuWorldState.GetAllEntities()`, tests each against a + ray-sphere intersection with the entity's bounding radius, and returns + the closest hit. A special-case inside-sphere origin guard (commit `5821bdc`) + ensures the pick works even when the cursor origin is already inside an + entity's bounding sphere (common for large portals or doors at close range). + `[B.4b] pick guid=0x7A9B4015 name=Door` logged on hit. + +6. **Use message** — `GameWindow` stores `_selectedGuid = picked.Guid` and + calls `InteractRequests.BuildUse(seq, guid)`. The resulting `0xF7B1 / 0x0036` + game message is sent to ACE via `_liveSession.SendGameMessage(body)`. + `[B.4b] use guid=0x7A9B4015 seq=N` logged. + +7. **ACE processes the Use** — ACE's `Door.Open()` flips the door's physics + flags to `ETHEREAL | ...` and broadcasts `SetState (0xF74B)` with the + new state value. + +8. **SetState arrives** — `WorldSession.OnSetState` parses the 12-byte + payload (Guid + PhysicsState + InstanceSeq + StateSeq) and fires + `WorldSession.StateUpdated`. `GameWindow.OnLiveStateUpdated` handles it. + **New as of commit `08be296` (slice 1c):** the handler translates + `parsed.Guid` (server GUID `0x7A9B4015`) to `entity.Id` (local entity ID + `0x000F4245`) via `_entitiesByServerGuid` before calling + `ShadowObjectRegistry.UpdatePhysicsState`. Without this translation the + registry lookup always returned "not found" — a silent no-op. + Log: `[setstate] guid=0x7A9B4015 entityId=0x000F4245 state=0x0001000C`. + +9. **Collision exemption** — next physics tick, `FindObjCollisions` calls + `CollisionExemption.ShouldSkip(entry.State, entry.Flags, moverState)`. + **New as of commit `a6e4b57` (slice 1b):** the check fires on + `(state & ETHEREAL_PS) != 0` alone (widened from the original `ETHEREAL && + IGNORE_COLLISIONS` conjunction). Because ACE broadcasts only `ETHEREAL` + in the low bits (`state=0x0001000C`), the original conjunction never fired; + the door stayed solid. + +10. **Player walks through** — the resolver produces no wall-contact response + for the door's collision geometry. User confirms: "Now I can walk through." + +### Observed log evidence + +``` +[input] SelectDblLeft DoubleClick +[B.4b] pick guid=0x7A9B4015 name=Door +[B.4b] use guid=0x7A9B4015 seq=N +[setstate] guid=0x7A9B4015 entityId=0x000F4245 state=0x0001000C +``` + +Player walks through the closed door after the `setstate` line. + +--- + +## The four bonus discoveries + +### 1. InputDispatcher had no double-click detection (`242ce70`) + +**Root cause:** `InputDispatcher.OnMouseDown` only looked up `Press` and +`Hold` activations in the binding table. The `SelectDblLeft` binding was +wired to the chord `[MouseLeft, DoubleClick]` in `KeyBindings.cs:300-320` +(shipped in B.4, 2026-04-28), but the dispatcher's mouse-down handler +never set activation to `DoubleClick` — it always produced `Press`. +So `SelectDblLeft` was literally unreachable: the chord required +`DoubleClick` to match, but the dispatcher never generated it. + +**Fix:** Added a `_lastMouseDownTime` (and `_lastMouseDownButton`) tracker +to `InputDispatcher`. In `OnMouseDown`, if the same button fires within +500ms of its last press, activation is `DoubleClick`; otherwise `Press`. +500ms matches the standard Windows/macOS double-click threshold. + +**Rationale:** The fix is minimal and correct. A more faithful retail +implementation might read the OS's configured double-click interval, but +500ms is the retail default and was the right call for now. 4 new unit +tests cover the timing logic: first click = Press, second click within +500ms = DoubleClick, third click = Press again (resets the window), and +button mismatch = Press. + +### 2. OnInputAction gate discarded DoubleClick activations (`58b95bc`) + +**Root cause:** Even after discovery #1 was fixed and `SelectDblLeft DoubleClick` +fired from the dispatcher, the event handler had an early-return guard at +the top of `GameWindow.OnInputAction`: + +```csharp +if (activation != InputActivation.Press) return; +``` + +This guard was introduced to prevent `Hold` repetition from triggering +switch cases intended for one-shot actions. It correctly blocked `Hold` +but also blocked `DoubleClick` — so the `SelectDblLeft` case was still +unreachable even after the dispatcher started generating `DoubleClick`. + +**Fix:** Widened the guard to let both `Press` and `DoubleClick` through: + +```csharp +if (activation != InputActivation.Press && activation != InputActivation.DoubleClick) return; +``` + +**Rationale:** `DoubleClick` is semantically a one-shot activation (fires +once per double-click gesture), so it belongs in the same pass-through +group as `Press`. `Hold` repetition remains blocked. + +### 3. CollisionExemption required both ETHEREAL + IGNORE_COLLISIONS (`a6e4b57`) + +**Root cause:** The original `CollisionExemption.ShouldSkip` check was +ported faithfully from `acclient_2013_pseudo_c.txt:276782`, which requires +**both** `ETHEREAL_PS (0x4)` and `IGNORE_COLLISIONS_PS (0x10)` to be set +simultaneously before short-circuiting collision detection. Retail servers +send both bits when opening a door, so retail clients see `state ≥ 0x14`. + +However, ACE's `Door.Open()` broadcasts only the `ETHEREAL` bit in the +low portion of the state word. The observed wire value was +`state=0x0001000C`: bit `0x4` (ETHEREAL) is set, bit `0x10` +(IGNORE_COLLISIONS) is not. The `&&` conjunction in `ShouldSkip` evaluated +to false → door stayed solid even after the registry update. + +This was the exact scenario the L.2g slice 1 Important review note warned +about (see L.2g handoff §"One Important review note"): *"ACE's +`PhysicsObj.cs:787-791` may set both bits... but this is not verified by +the test suite. The B.4b visual test will settle this definitively."* +It settled as: ACE sends `0x4` alone, not `0x14`. + +**Fix:** Widened the short-circuit to fire on `ETHEREAL` alone: + +```csharp +// Widened from (ETHEREAL && IGNORE_COLLISIONS) — ACE Door.Open() sends +// ETHEREAL alone (state=0x0001000C); retail servers send both. +// Pragmatic choice: exempt on ETHEREAL-bit-alone until full retail +// obstruction_ethereal flag path is ported. +if ((state & ETHEREAL_PS) != 0) return true; +``` + +**Rationale:** The deeper retail path (pseudo-C line 276795 sets +`obstruction_ethereal=1` and routes through downstream movement handling) +was not ported — that's a more invasive change requiring more testing. The +pragmatic widening to ETHEREAL alone is correct for ACE's Door behavior and +matches the spirit of the retail check (ETHEREAL means "pass through me"). +If a future retail-server emulator sends both bits, the widened check still +fires (ETHEREAL is a subset of ETHEREAL+IGNORE_COLLISIONS). + +### 4. ServerGuid → entity.Id translation missing in OnLiveStateUpdated (`08be296`) — THE actual blocker + +**Root cause:** `ShadowObjectRegistry` is keyed by local `entity.Id` (the +per-session integer ID assigned by `GpuWorldState` at entity registration, +e.g. `0x000F4245`). The `GameWindow.OnLiveStateUpdated` handler was passing +`parsed.Guid` — the **server GUID** broadcasted in the `SetState` packet +(e.g. `0x7A9B4015`) — directly to `UpdatePhysicsState`. Because the registry +has no entry keyed by server GUID, the lookup always returned "not found" +and the state mutation was silently dropped. The registry stayed at +`state=0x00000000` (closed, solid) regardless of how many times the door +was clicked. + +This is why discoveries 1-3 alone were insufficient: even with double-click +detection working, the correct gate firing, and `CollisionExemption` +widened, the registry still held the stale closed state and the door +stayed solid. + +**Fix:** Added a `_entitiesByServerGuid` reverse-lookup dictionary to +`GameWindow` (populated at entity registration in `OnLiveCreateObject`). +`OnLiveStateUpdated` now does: + +```csharp +if (_entitiesByServerGuid.TryGetValue(parsed.Guid, out var entity)) + _physicsEngine.ShadowObjects.UpdatePhysicsState(entity.Id, parsed.PhysicsState); +``` + +The `entityId=` field was added to the `[setstate]` diagnostic log line +specifically to make this translation visible and greppable: +`[setstate] guid=0x7A9B4015 entityId=0x000F4245 state=0x0001000C`. + +**Why this was missed:** L.2g slice 1's unit tests operated at the +`ShadowObjectRegistry` level directly, calling `UpdatePhysicsState` with +an `entity.Id` (not a server GUID). The integration was never exercised +end-to-end before B.4b's visual test. The two tests `UpdatePhysicsState_FlipsEthereal_*` +were correct in isolation; the broken layer was one level above them +(the handler → registry call site). + +**Why the "multiple doors" misdiagnosis occurred:** Before slice 1c was +identified, the `[resolve]` probes showed wall hits attributed to +`obj=0x000F4245` while the clicked door's ServerGuid was `0x7A9B4015`. +Initial read: "these are two different entities blocking the threshold." +Slice 1c clarified: both IDs refer to the same door — `0x000F4245` is +the local entity ID, `0x7A9B4015` is the server GUID for the same entity. +The ID-space mismatch was the cause of both the collision-not-clearing +AND the "different object" misread. + +--- + +## Open notes / follow-ups + +### Door swing animation (#58) + +When ACE opens a door it broadcasts **two** packets, not one: + +1. `SetState (0xF74B)` — the collision-bit flip. **Handled by L.2g slice 1.** +2. `UpdateMotion (0xF74D)` with stance/command `(NonCombat, On)` — the + swing animation cycle. **NOT handled.** + +acdream's `UpdateMotion` pipeline is currently scoped to player + creature +animation (Phase L.3). Non-creature entities like doors do not receive +cycle commands. The door therefore opens (becomes passable) but has no +visible swing animation. + +Filed as **issue #58**. Scope is unknown — routing `UpdateMotion` to +non-creature `WorldEntity` instances could be quick (few lines), or the +`AnimationSequencer` may have creature-specific assumptions that require +audit first. Filed as M1-deferred polish; it does not block the demo +scenario. + +### Door toggle behavior + +ACE doors toggle on each Use: first double-click opens, subsequent +double-click closes (re-sends `SetState` with `state=0x00000000`, restoring +collision). This is correct ACE behavior and matches retail. No issue to file. + +Rapid double-clicks (faster than ACE's server-tick processing) will open +then close in quick succession — each Use lands as a distinct game action. +Expected behavior; no fix needed. + +### Multiple-door misdiagnosis (historical note) + +While slice 1c was still unidentified, the `[resolve]` diagnostic showed: + +``` +[resolve] ... obj=0x000F4245 wall hit +[B.4b] use guid=0x7A9B4015 ... +[setstate] guid=0x7A9B4015 state=0x0001000C +[resolve] ... obj=0x000F4245 wall hit (unchanged!) +``` + +Initial misdiagnosis: there must be a *different* door entity (`0x000F4245`) +blocking the threshold whose state was never updated. Slice 1c revealed: +both IDs refer to the same door — one is the server GUID (network space), +the other is the local entity ID (registry space). The registry update was +targeting the server GUID (which missed), so the local-ID-keyed entry +stayed solid. + +### Selection HUD / hover-highlight / brackets + +Out of B.4b scope per design spec §Non-goals. The `_selectedGuid` field on +`GameWindow` is populated (stores the last-picked entity's server GUID), but +nothing renders a selection bracket, hover highlight, or target nameplate. +That is M2/M3 HUD work (Phase D.6). + +### BuildPickUp (F key) + UseWithTarget UX + +`InteractRequests.BuildPickUp` exists (as an alias of `BuildUse`). The +`SelectionPickUp` input action and the F-key binding exist. But +`OnInputAction` has no case for `SelectionPickUp` — pick-up-by-F-key is +still unimplemented. Same for `UseWithTarget` (requires a secondary target +selection UX). Both deferred to a follow-up phase; not M1-blocking. + +--- + +## Next session + +**M1 demo progress as of this branch:** +- ✅ "walk through Holtburg without getting stuck" — Phase L.2 in progress (outdoor collision works; CBuildingObj interior still deferred to L.2d). +- ✅ "open the inn door" — **done** (B.4b, this branch). +- ⬜ "click an NPC" — pick + Use wiring exists now; depends on ACE NPC handler responding to Use. +- ⬜ "pick up an item" — `BuildPickUp` + F-key wiring not yet in `OnInputAction`. + +**Recommended next steps (in M1 critical-path order):** + +1. **Door swing animation (#58)** — cosmetic M1 polish.
