Parse bounding vertices, triangles, and normals from M2 files and use
them for proper triangle-level collision instead of AABB heuristics.
Spatial grid bucketing for efficient queries, closest-point wall push
with soft clamping, and ray-triangle floor detection alongside existing
AABB fallback.
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.
CMSG_TRAINER_BUY_SPELL was missing the trainerId field — server expects
guid(8) + trainerId(4) + spellId(4) = 16 bytes, not 12. Spells with
unmet prerequisites (chainNode1/2/3), insufficient level, or already
known are now greyed out with disabled Train buttons. Tooltips show
prerequisite status in green/red.
Fix SMSG_BINDPOINTUPDATE opcode from 0x1B3 to 0x155 — the old value
collided with SMSG_TRAINER_BUY_SUCCEEDED, causing buy responses to be
misinterpreted as bindpoint updates. Add specialization tabs using
SkillLineAbility.dbc to group spells by class spec (category 7).
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
Add 36 arena and battleground opcodes with handlers for queue status, team events, invites, and errors. Fix SMSG_FORCE_RUN_SPEED_CHANGE parsing (uint8 not uint32) and remove manual mount speed tracking. Buff bar now shows spell icons and is positioned below the minimap. Both mouse buttons cancel autorun.
TaxiNodes.dbc name was read from field 6 (Korean locale, empty) instead
of field 5 (enUS). Add BFS-based cost computation from TaxiPath.dbc
edges and display gold/silver/copper next to each destination.
- Rider character bobs with mount's run animation (sinusoidal, 0.12u amplitude)
- Mount hoofbeat footstep sounds triggered at 4 points per animation cycle
- M key opens map directly to player's current zone instead of continent
- Mouse wheel scroll zooms map in/out between world, continent, and zone views
- Fog of war darkens unexplored zones on continent view, clears on visit
- Fix SMSG_FORCE_RUN_SPEED_CHANGE parsing (missing uint32 field caused garbage speed)
- Always send speed ACK to prevent server stall, even on invalid values
- Defer mount model loading to next frame to avoid render-loop hang
- Compute mount height from tight vertex bounds instead of M2 header bounds
- Dismount when entering combat or casting spells while mounted
- Prevent auto-attacking yourself when self-targeted
- Leave combat when 40+ yards from target, close vendor at 15+ yards
- Pre-open X11 display for reliable mouse release in signal handlers
Render mount M2 model under player with seated animation, apply creature
skin textures, server-driven speed via SMSG_FORCE_RUN_SPEED_CHANGE, and
/dismount command. X11 XUngrabPointer on crash/hang to always release mouse.
- M2 interior darkening now uses global player-inside-WMO flag instead
of per-instance queries that were unreliable
- Fix carpet/rug sliding by skipping lateral collision push when player
is standing on top of any stepable low object, not just platforms
The previous approach used getFloorHeight which has tight spatial query
bounds and couldn't find WMO floors far above the player. Now uses
reset() which does multi-radius WMO/terrain scanning.

- Fix spawning under Stormwind with online-mode camera controller reset
Sweep step size reduced from 1.0f back to 0.65f with max 3 steps (was 2)
to prevent clipping through ramps in Stormwind. All paths updated: follow,
free-fly, and swimming.
Shadows disabled by default in renderer, settings UI, and settings defaults.
Spawn fix: floor probe used terrain height (underground) instead of server
position when searching for spawn floor. Now probes from max(terrain, serverZ)
so WMO city surfaces above terrain are found correctly. Also invalidates
floor cache on respawn.
Delete button: moved from details panel to bottom row (small, red, far right).
Two-stage confirmation with modal popups: first asks "are you sure", second
warns "THIS CANNOT BE UNDONE" with red DELETE PERMANENTLY button.
- Skip wall collision sweep entirely when player isn't moving (saves all
collision calls when standing still)
- Reduce max sweep steps from 4 to 2 with 1.0f step size (all paths:
follow, free-fly, swimming)
- Cache floor height between frames, reuse when position changes <0.5 units
- Fix floor height not updating after walking off tall objects (fountain etc)
by always smoothing toward detected ground instead of ignoring drops >2 units
- Reduce free-fly ground probes from 5 to 1
- Disable WMO camera collision (raycast + floor probes) for performance
- Add spatial grid to raycastBoundingBoxes for when camera collision is re-enabled
Build a 2D triangle grid per WMO group at load time so getFloorHeight and
checkWallCollision only test triangles in nearby cells instead of brute-forcing
all triangles. Also reduce sweep steps (12→4), ground probes (3→1), camera
floor probes (5→2), throttle isInsideWMO to every 10 frames, and early-out
wall collision on first hit.
- Fix CMSG_BUY_ITEM count field from uint8 to uint32 (server silently dropped undersized packets)
- Character select screen: remember last selected character, two-column layout with details panel, double-click to enter world, responsive window sizing
- Fix stale character data between logins by replacing static init flag with per-character GUID tracking
- Parallelize WMO visibility culling across worker threads (same pattern as M2 renderer)
- Optimize WMO collision queries with world-space group bounds early rejection in getFloorHeight, checkWallCollision, isInsideWMO, and raycastBoundingBoxes
- Reduce camera ground samples from 5 to 3 movement-aligned probes
- Add WMO interior lighting, unlit materials, vertex color multiply, and alpha blending support
Split the M2 animation update loop into three phases: sequential animation state update, parallel bone matrix computation via std::async (when 32+ animated instances), and sequential particle update. Each thread processes a disjoint slice of instances so no synchronization is needed.
Extract skill data from PLAYER_SKILL_INFO_1_1 update fields (636-1019), detect
