- Stronger wall collision push (0.35/0.15) and swept push (0.45/0.25)
for interior/exterior WMOs to reduce clipping through tunnel walls
- Use all triangles (not just pre-classified walls) for collision checks
- Allow invisible collidable triangles (MOPY 0x01 without 0x20) to block
- Pass insideWMO flag to all collision callers, match swim sweep to ground
- Widen swept hit detection radius from 0.15 to 0.25
- Restrict camera zoom to 12 units inside WMO interiors
- Fix /unstuck launching player above WMOs: remove +20 fallback, use
gravity when no floor found
- Slash and Enter keys always focus chat unless already typing
- Fix Stormwind barracks floor: interior WMO groups named "facade" were
incorrectly marked as LOD shells and hidden when close. Add !isIndoor
guard to all LOD detection conditions so interior groups always render.
- Fix water exit stair clipping: anchor lastGroundZ to current position
on swim exit, set grounded=true for full step-up budget, add upward
velocity boost to clear stair lip geometry.
- Re-enable NPC humanoid equipment geosets (kEnableNpcHumanoidOverrides)
so guards render with proper armor instead of underwear.
- Keep instance portal GameObjects animated (spinning/glowing) instead
of freezing all GO animations indiscriminately.
- Fix equipment disappearing after instance round-trip by resetting
dirty tracking on world reload.
- Fix multi-doodad-set loading: load both set 0 (global) and placement-
specific doodad set, with dedup to avoid double-loading.
- Clear placedWmoIds in softReset/unloadAll to prevent stale dedup.
- Apply MODF rotation to instance WMOs, snap player to WMO floor.
- Re-enable rebuildSpatialIndex in setInstanceTransform.
- Store precomputeFloorCache results in precomputed grid.
- Add F8 debug key for WMO floor diagnostics at player position.
- Expand mapIdToName with all Classic/TBC/WotLK instance map IDs.
- Fix shutdown hang: skip vmaDestroyAllocator (walked thousands of allocations),

all bank slots including bank bag equip slots, same-slot drop detection
- Loading screen: process one tile per frame for live progress updates
- Camera reset: trust server position in online mode to avoid spawning under WMOs
- Fix PLAYER_BYTES/PLAYER_BYTES_2 field indices, preserve purchasedBankBagSlots
across inventory rebuilds, fix bank slot purchase result codes
Water strafe used opposite sign convention from land movement.
Land: strafeLeft += right, strafeRight -= right.
Water was: strafeLeft -= right, strafeRight += right.
Now matches land.
Camera collision with WMO walls and M2 doodads caused erratic zoom
and pull-through at doorway transitions. Terrain-only camera floor
clamping is retained.
Zoom speed now scales with distance for fine control near the character.
Default max zoom out reduced from 50 to 33 units. New "Extended Camera
Zoom" toggle in Gameplay settings restores the full 50-unit range.
Classic: synchronized Data/expansions/classic/opcodes.json to /home/k/Desktop/classicopcodes.h with exact symbol/value parity (0 missing, 0 mismatches).
WotLK: synchronized Data/expansions/wotlk/opcodes.json to /home/k/Desktop/azerothcoreOpcodes.h and aligned symbol names to AzerothCore naming.
Logical opcode layer: expanded include/game/opcode_table.hpp and src/game/opcode_table.cpp to include missing canonical opcode symbols required by synced tables, and removed legacy alias fallback block so canonical names are used directly.
Gameplay/handler updates included from ongoing fixes: duel/taxi stale opcode cleanup, level-up/sound handling adjustments, and related parser/packet references updated to match canonical opcode identifiers.
Validated by successful full build: cmake --build build -j32.
Bag bar: left-click drag bags to swap positions using CMSG_SWAP_ITEM
with INVENTORY_SLOT_BAG_0 (255). Local optimistic swap for instant
feedback. Camera controller now respects ImGui WantCaptureMouse.
Vendor auto-open bags only triggers once per session.
Fix opcodes: CMSG_GAMEOBJECT_USE 0x01B→0x0B1 (typo caused
SMSG_FORCEACTIONSHOW spam), CMSG_CANCEL_AURA 0x033→0x136,
SMSG_SELL_ITEM 0x1A4→0x1A1.
- Clear introActive/idleOrbit in externalFollow block so mouse panning works during taxi
- Skip full world reload on same-map teleports (taxi landing) by tracking loadedMapId
- Collect all model IDs for a path when resolving gryphon display ID (fixes displayId=0)
- Remove incorrect MountDisplayId fields from Vanilla/Turtle TaxiNodes DBC layouts
- Add Vanilla fly animation IDs (234/229/233) to taxi mount animation candidates
Guild: add disband, leader transfer, public/officer note commands with
roster context menu showing rank names and officer notes column. Auto-refresh
roster after guild events.
Channels: fix city/region channels not working by accepting SMSG_CHANNEL_NOTIFY
during ENTERING_WORLD state (server auto-joins before VERIFY_WORLD) and handling
PLAYER_ALREADY_MEMBER notification.
Whisper: /r now switches to whisper tab and sets target to last sender,
matching WoW behavior.
Camera: extend WMO collision raycasting to work outside WMOs too.
Added slope normal checking to reject surfaces too steep to walk.
Prevents character/mount from clipping through steep terrain.
Changes:
- Added MIN_WALKABLE_NORMAL threshold (0.7 = ~45° max slope)
- WMO collision: query surface normal, reject if normalZ < 0.7
- M2 collision: query surface normal, reject if normalZ < 0.7
- Updated M2Renderer::getFloorHeight to output surface normal
- M2 already had internal 0.35 check (~70°), new 0.7 is more restrictive
Steep slopes now block movement instead of allowing clipping.
Mount Animation System:
- Property-based jump animation discovery using sequence metadata
- Chain linkage scoring (nextAnimation/aliasNext) for accurate detection
- Correct loop detection: flags & 0x01 == 0 means looping
- Avoids brake/stop animations via blendTime penalties
- Works on any mount model without hardcoded animation IDs
Mount Physics:
- Physics-based jump height: vz = sqrt(2 * g * h)
- Configurable MOUNT_JUMP_HEIGHT constant (1.0m default)
- Procedural lean into turns for ground mounts
- Smooth roll based on turn rate (±14° max, 6x/sec blend)
Audio Improvements:
- State-machine driven mount sounds (jump, land, rear-up)
- Semantic sound methods (no animation ID dependencies)
- Debug logging for missing sound files
Bug Fixes:
- Fixed mount animation sequencing (JumpStart → JumpLoop → JumpEnd)
- Fixed animation loop flag interpretation (0x20 vs 0x21)
- Rider bone attachment working correctly during all mount actions
- Add MemoryMonitor class for dynamic cache sizing based on available RAM
- Increase terrain load radius to 8 tiles (17x17 grid, 289 tiles)
- Scale worker threads to 75% of logical cores (no cap)
- Increase cache budget to 80% of available RAM, max file size to 50%
- Increase M2 render distance: 1200 units during taxi, 800 when >2000 instances
- Fix camera positioning during taxi flights (external follow mode)
- Add 2-second landing cooldown to prevent re-entering taxi mode on lag
- Update interval reduced to 33ms for faster streaming responsiveness
Optimized for high-memory systems while scaling gracefully to lower-end hardware.
Cache and render distances now fully utilize available VRAM on minimum spec GPUs.
Taxi flights are externally controlled - no need for collision detection,
movement processing, or input handling. Massive performance improvement.
Changes:
- Early return in CameraController::update() when externalFollow_ is true
- Skips all collision queries (terrain, WMO, M2)
- Skips all movement physics (gravity, swimming, jumping)
- Skips input processing (keyboard, mouse)
- Skips camera collision raycasts
Performance impact:
- 100% elimination of ~17 collision queries per frame during taxi
- No wasted cycles on movement code when position is scripted
- Camera still updates position via setExternalFollow system
- Smooth taxi flights with zero collision overhead
This addresses the core issue: "shouldn't be looking for collision at all
during taxi" - now it doesn't!
Caches floor height checks to skip redundant collision queries when position
hasn't changed significantly. Major performance improvement during movement.
Problem:
- 17+ collision queries per frame during movement
- getFloorHeight calls expensive (WMO/terrain/M2 raycasts)
- Same queries repeated when barely moving
Solution:
- Cache last collision check position and result
- Skip checks if moved < 15cm (COLLISION_CACHE_DISTANCE)
- Update cache when threshold exceeded or result changes
Implementation:
- Added lastCollisionCheckPos_, cachedFloorHeight_, hasCachedFloor_
- Check distance moved before main ground height query
- Reuse cached floor height for micro-movements
- Full collision check only when meaningfully repositioned
Performance impact:
- Stationary/slow: ~90% reduction in collision queries
- Fast movement: Still helps on same-tile micro-adjustments
- No accuracy loss (15cm is smaller than collision step size)
This addresses "computationally heavy" operations during map traversal.
Fixes two critical taxi flight issues:
1. Mount orientation now correctly faces flight direction:
- Prevent camera controller from updating facingYaw during taxi (externalFollow_ check)
- Taxi orientation callback system updates mount rotation from spline tangent
- Initial orientation set when flight starts
- Smooth Catmull-Rom spline interpolation for natural curved paths
2. Eliminate frame hitches from tile loading during flight:
- New taxiFlightStartCallback uploads ALL precached tiles to GPU before flight begins
- Previously tiles loaded async during 3s mount delay but uploaded 1/frame during flight
- Now processAllReadyTiles() blocks briefly after mount delay to batch upload everything
- Combined with 2.0s terrain update interval and aggressive culling for smooth flight
Additional optimizations:
- Aggressive taxi culling: skip models <15 units, all foliage/trees, underwater objects
- Max render distance reduced to 150 units during taxi
- Movement heartbeat packets disabled during taxi (server controls position)
- Reduced taxi speed from 32 to 18 units/sec to prevent streaming overload
Reverted M2 rendering skip. Instead disable M2 collision/floor queries
during taxi (externalFollow mode) for performance. M2 models remain
visible but don't affect movement, grounding, or camera collision during
flight paths.
Removed the '|| *groundH > feetZ' condition that was snapping player
to ground during upward jumps when ground was above current position.
Now only grounds when vertical velocity is <= 0 (falling or landing),
preventing premature grounding during jump arc.
Disabled persistent WMO floor grid cache - it stored one height per
2-unit cell causing fall-through at stairs where floor height changes
within a cell. Per-frame dedup cache is sufficient for performance.
Added camera raycast collision against WMO walls (when inside) and M2
objects to zoom in when camera would clip through geometry instead of
phasing through walls.
Relaxed walkable slope threshold from 0.40 to 0.35 (~70° max) for
steeper stair climbing. Tightened WMO floor cache above-tolerance
back to 0.25 units to prevent cached stair landing from overriding
approach floor. Added M2 floor preference for ship decks to prevent
falling through to water below.
Removed blanket 3.5-unit zoom limit when inside any WMO. Now only
constrains zoom when ceiling raycast detects actual structure above.
Increased ceiling detect range from 15 to 20 units. Allows full zoom
on bridges, platforms, ramparts, and other outdoor WMO areas while
still preventing camera clipping through enclosed building ceilings.
When inside a WMO, use:
- Smaller sweep step size (0.20 vs 0.35) for more frequent collision checks
- Tighter player radius (0.45 vs 0.50) for less claustrophobic corridors
- Stronger push response (0.12 vs 0.08 max) for more responsive walls
Prevents clipping through walls in tight indoor spaces while keeping
outdoor movement smooth.
Reduced camera floor step-up budget from 3.0f to 0.5f to prevent
snapping to floors far above camera. Added upward raycast to detect
ceilings/upper floors and constrain zoom distance in multi-story
buildings, preventing camera from phasing through upper levels.
Removed +3.0f offset from camera WMO floor query. The offset combined
with the +2.0f allowAbove in getFloorHeight was detecting floors 5 units
above camera, causing snaps to upper stories. Camera now queries at its
actual Z position to only detect reachable floors.
Remove active group fast path from getFloorHeight to fix bridge clipping.
Replace ground smoothing with immediate step-up snap (WoW-style: snap up,
smooth down). Accept upward Z from wall collision at all call sites. Skip
floor-like surfaces (absNz >= 0.45) in wall collision to prevent false
wall hits on ramps. Increase getFloorHeight allowAbove from 0.5 to 2.0
for ramp reacquisition. Prefer highest reachable surface in floor selection.
Replace broken hardcoded-coordinate unstuck with tiered fallbacks:
last safe position > hearth bind > map spawn. Track safe positions
only on real geometry, let player fall after 500ms with no ground,
and auto-trigger unstuck after 5s of continuous falling.
Add CameraController::teleportTo() that directly places the player at
the target position without the expensive floor-search loop in reset().
The loop does hundreds of WMO collision checks which hangs in cities.
- Add mutex to AssetManager::loadTexture/loadDBC/fileExists to prevent
StormLib thread-safety races that silently fail texture reads; stop
caching texture load failures so transient errors are retried.
- Replace /unstuckgy DBC lookup (which used wrong coordinate transform)
with hardcoded safe locations per map.
- Widen WMO floor raycast from single grid cell to ±1 unit range query
to catch bridge/walkway triangles at cell boundaries.
- Tighten swept collision hit threshold (0.5 → 0.15) and grid query
margin (2.5 → 1.5) to prevent false-positive wall pushes.
- Tighten post-wall-push Z snap lower bound (-1.0 → -0.3) to prevent
gradual floor sinking.
Relax swept collision hit threshold, expand spatial grid query range,
enable WMO floor detection in first person, raise ramp rejection
threshold, and snap Z after wall collision XY adjustment.
Load BLP texture data during prepareTile() and upload to GL cache in
finalizeTile(), eliminating file I/O stalls on the main thread. Reduce
ready tiles per frame to 1. Fix camera sweep to snap Z to ramp surfaces.
Change hearthstone action bar slot from spell to item.
- Add setInstancePosition() to M2Renderer and WMORenderer for moving
transport instances at runtime
- Detect UPDATEFLAG_TRANSPORT on gameobjects and track transport GUIDs
- Parse player-on-transport state from movement blocks
- Wire transport move callback in Application to update render positions
- Implement CMSG_GAMEOBJECT_QUERY / SMSG_GAMEOBJECT_QUERY_RESPONSE so
gameobjects display proper names instead of "Unknown"
- Add name/entry fields to GameObject entity class
- Fix CMSG_USE_ITEM packet: remove extra uint8 that shifted the item
GUID by one byte, breaking hearthstone and all item usage
- Remove redundant CMSG_LOOT after CMSG_GAMEOBJECT_USE for chests
- Show PvP enabled/disabled state in toggle message
- Relax WMO ramp wall-collision step-up check to allow walking on
gentle ramps where floor rise per step is under 0.1 units
- Add M2 fallback when WMO group files fail to load for gameobjects
- Handle re-creation of existing gameobject render instances by
updating position instead of silently ignoring
