From d640ed74e1f586698ff21ec604c6a26abbcc0404 Mon Sep 17 00:00:00 2001 From: Erik Date: Sat, 16 May 2026 16:14:44 +0200 Subject: [PATCH] =?UTF-8?q?feat(retail):=20Phase=20B.6=20=E2=80=94=20serve?= =?UTF-8?q?r-driven=20auto-walk=20done=20right?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Closes #63, #69, #74, #75. Replaces the chain of Commit-B workarounds that compensated for ACE's MoveToChain getting cancelled by a leaked user-MoveToState packet during inbound auto-walk. The fix is architectural — auto-walk drives the body directly from the server-supplied path data, no player-input synthesis, no spurious wire-packet transitions, no grace-period band-aid. Architectural change (closes #75): PlayerMovementController.ApplyAutoWalkOverlay → DriveServerAutoWalk. - Steps Yaw toward target at retail-faithful turn rates. - Computes desired forward velocity from path runRate. - Calls _motion.DoMotion(WalkForward, speed) directly for the motion-interpreter state (drives animation cycle). - Sets _body.set_local_velocity directly when grounded. - Returns true to gate the user-input motion + velocity section in Update so user-input flow doesn't overwrite auto-walk velocity or motion state. Mirrors retail's MovementManager::PerformMovement case 6 (decomp 0x00524440) which never touches the user-input pipeline during server-controlled auto-walk. Wire-layer guard at GameWindow.cs:6419 retained as a SEMANTIC statement (`if (result.MotionStateChanged && !IsServerAutoWalking)`): user-MoveToState packets are for user-driven motion intent. During server-controlled auto-walk, the motion-state transitions caused by the animation override (RunForward / WalkForward / TurnLeft / TurnRight cycles) must not leak as user-cancellation packets. This is NOT the deleted 500ms grace-period band-aid; it's the wire-layer expressing the user-vs-server motion split. Animation plumbed for auto-walk phases (closes #69): - Moving forward → WalkForward (speed=1.0) / RunForward (speed=runRate) - Turn-first phase → TurnLeft / TurnRight (sign of yawStep) - Aligned-but-pre-step / arrival → no override (idle) Driven via _autoWalkMovingForwardThisFrame + _autoWalkTurnDirectionThisFrame fields set in DriveServerAutoWalk and read in the MovementResult construction at the bottom of Update. UpdatePlayerAnimation picks up the localAnimCmd as the highest-priority animation source. Walk/run threshold = 1.0m, retail-observed. ACE's wire-default of 15.0f is too generous; ACE's own physics layer uses 1.0f at MovementParameters.cs:50 (with the 15.0f line commented out) and Creature.cs:312 notes "default 15 distance seems too far". The formula matches retail's MovementParameters::get_command at decomp 0x0052aa00: running = (initialDist - distance_to_object) >= threshold, evaluated ONCE at chain start and held for the rest of the auto-walk (matches retail "runs all the way / walks all the way" behaviour). Wire-supplied threshold is ignored. Pickup gate (IsPickupableTarget) now uses BF_STUCK (acclient.h:6435, bit 0x4) to discriminate immovable scenery from real pickup items that share a Misc ItemType. Sign (pwd=0x14 with BF_STUCK) → blocked; spell component (pwd=0x10, no BF_STUCK) → allowed. ACE's PutItemInContainer (Player_Inventory.cs:831-836) responds with WeenieError.Stuck (0x29) on stuck items so the gate prevents wasted wire packets + a UX dead-end. R-key dispatch by target type. UseCurrentSelection's top-level IsUseableTarget gate was wrong (blocked USEABLE_NO=1 items that ARE pickupable). Reordered: 1. Creature → SendUse 2. Pickupable → SendPickUp 3. Useable → SendUse 4. Otherwise → "cannot be used" toast Each handler keeps its own gate. Matches retail's per-action server-side validation. AP cadence revert (closes #74). With the MoveToChain race fixed, the per-frame "send while moving" cadence is no longer load-bearing. Reverted to retail's two-branch ShouldSendPositionEvent gate (acclient_2013_pseudo_c.txt:700233-700285): Interval NOT elapsed (< 1 sec): send if cell or contact-plane changed. Interval elapsed (>= 1 sec): send if cell or position frame changed. Adds _lastSentContactPlane field + ApproxPlaneEqual helper + PlayerMovementController.ContactPlane public accessor. Extended NotePositionSent(Vector3, uint, Plane, float) — both outbound sites (MoveToState + AP) pass _playerController.ContactPlane. Effective rates: 0 Hz idle, ~1 Hz smooth motion, per-event on cell/plane changes, 0 Hz airborne. CLAUDE.md updated with no-workarounds rule (commit `da126f9` on the worktree branch). Saved as feedback memory at memory/feedback_no_workarounds.md. Tests: build green; Core.Net 294/294; Core 1073/1081 (baseline, 8 pre-existing Physics failures unchanged). Visual-verified end-to-end on 2026-05-16 for far/near Use + PickUp on NPCs, doors, items, spell components, signs (correctly blocked), corpses, turn-first animation, run/walk thresholds, idle quiet, smooth- motion 1Hz.
