- 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
- Implement flight path system: SMSG_SHOWTAXINODES parser, CMSG_ACTIVATETAXIEXPRESS builder, BFS multi-hop pathfinding through TaxiNodes/TaxiPath DBC, taxi destination UI, movement blocking during flight
- Fix WMO interiors too dark by boosting vertex color lighting multiplier
- Dim M2 objects inside WMO interiors (rugs, furniture) via per-instance interior detection
- Fix ramp/stair clipping by lowering wall collision normal threshold from 0.85 to 0.55
- Restore 5-sample cardinal footprint for ground detection to fix rug slipping
- Fix /unstuck command to reset player Z to WMO/terrain floor height
- Handle MSG_MOVE_TELEPORT_ACK and SMSG_TRANSFER_PENDING for hearthstone teleports
- Fix spawning under Stormwind with online-mode camera controller reset
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.
Replace flat mesh rendering of additive/mod blend batches (blendMode >= 3)
with camera-facing point sprites using a soft radial gradient texture and
additive blending. Adds M2 particle emitter infrastructure (structs, shader,
parsing stubs) but disables emitter parsing — the assumed 476-byte struct
size is wrong for WotLK 3.3.5a, causing misaligned reads that explode RAM.
These batches are particle emitter placeholder geometry (glow halos,
light volumes) that render as visible transparent discs without a proper
particle system. Skip them entirely instead of attempting to render as
raw mesh geometry.
Disable depth testing for additive/mod blend mode batches so glow quads
render as proper light halos instead of visible transparent discs. Add
NPC swing callback to play attack animation (anim 16) when NPCs melee
in single-player combat.
Batches with the M2 unlit material flag (0x01) or additive blend modes
(3+) now skip lighting, shadows, and fog, emitting texture color directly.
Fixes lantern glow quads appearing as dull transparent circles.
Water/lava batches in fountain and Ironforge M2 models use non-opaque
blend modes (alpha, additive) defined in the M2 material table. Without
parsing these, they rendered as solid surfaces extending visibly beyond
their containers. Now each batch looks up its blend mode from the
material array and sets the appropriate GL blend function.
Parse M2TextureTransform entries and texture transform lookups from the
M2 binary, then apply per-batch UV offsets in the vertex shader using
the existing animation time base and global sequence durations.
Replace hardcoded specular multipliers with uLightColor * uSpecularIntensity
uniforms in all 4 world shaders (terrain, WMO, M2, character), set HDR sun
color (1.5, 1.4, 1.3) and specular intensity 0.5 so highlights can exceed
1.0, and switch the post-process pass from passthrough to exposure-compensated
Reinhard (exposure=1.8) for soft highlight roll-off without clipping.
Anisotropic filtering now queries GL_MAX_TEXTURE_MAX_ANISOTROPY_EXT once
and applies via a single applyAnisotropicFiltering() utility, replacing
hardcoded calls across all renderers. Fog (sky horizon color, 100-600
range) and Blinn-Phong specular highlights are added to WMO, M2, and
character shaders for visual parity with terrain. Shadow sampling
plumbing (sampler2DShadow with 3x3 PCF) is wired into all three shaders
gated by uShadowEnabled, ready for a future shadow map pass.
Replace UV scroll workaround for chimney smoke with proper GL_POINTS
particle system. Smoke particles rise, expand, drift, and fade over
4-7 seconds. One in eight particles spawns as a bright orange/red
ember spark. Enable 4x multisample antialiasing for smoother edges
on player models, fences, and foliage.
- Parse global sequence durations from M2 binary and use them in bone
interpolation so torches, candles, and other env doodads animate.
- Add UV scroll shader effect for smoke models (HouseSmoke, SmokeStack)
as a workaround for unimplemented M2 particle emitters.
- Tighten WMO floor probe heights to prevent multi-story buildings from
returning the wrong floor, fixing player clipping through inn floors
and camera locking onto the second floor.
- Use player ground level as reference for camera orbit floor collision
so the camera doesn't fight upper floors in buildings.
- Loading screen stays visible until all terrain tiles finish streaming;
character spawns only after terrain is loaded and Z-snapped to ground
- Reduce tree trunk collision bounds (5% of canopy, capped at 5.0) and
make all small/medium trees, bushes, lily pads, and foliage walkthrough
- Add jump input buffering (150ms) and coyote time (100ms) for responsive jumps
- Fix fence orientation by adding +180° heading rotation
- Increase terrain load radius from 1 to 2 (5x5 tile grid)
- Add hearthstone callback for single-player camera reset
- Add idle variation system: creatures randomly play Stand variations
(stretch, flap, look around) every 4-10s, then return to idle loop
- Deduplicate M2 instances at same position (was hidden before animation
made duplicates visible with different random start times)
- Adaptive M2 render distance: 350 units in open terrain, 180 in cities
- Restore terrain sampler-to-unit uniform bindings lost during texture
bind optimization (roads were invisible under grass)
- Safety: clamp bone count to 128, validate sequence indices, sanitize scale
- Implement GPU bone skinning for M2 doodads/creatures (gryphons, birds)
- Store bone hierarchy and animation keyframes per model
- Compute bone matrices per-instance with keyframe interpolation
- Upload bone weights/indices in vertex buffer, skinning in vertex shader
- Fix terrain texture rendering: restore sampler-to-unit uniform bindings
removed during texture bind optimization (roads were invisible)
- Add spellbook screen (P key) with Spell.dbc name lookup and action bar assignment
- Default Attack and Hearthstone spells available in single player
- Fix WMO floor clipping (gryphon roost) by tightening ceiling rejection threshold
- Darken ocean water, increase wave motion and opacity
- Add M2 model distance fade-in to prevent pop-in

- Remove debug key commands (keep only F1 perf HUD, N minimap)
- Performance: return chat history by const ref, use deque for O(1) pop_front
- Implement orbit camera with smooth zoom and collision detection
- Add 50° slope limiting with sliding (prevents mountain climbing)
- Add first-person mode that hides player model and weapons
- Add floor clearance check to prevent camera clipping through ground
- Improve WMO wall collision with proper height range checks
- Add two-sided floor collision detection for WMO geometry
- Increase M2 render distance slightly for better visibility
- Increase WMO render distance from 1500 to 3000 units for better city loading
- Increase M2 render distance from 500 to 1000 units
- Increase terrain load radius from 4 to 6 tiles (~3200 units)
- Add raycast-based camera collision that zooms in when obstructed by walls/objects
- Move spawn point outside chapel to road near Stormwind gate
- Add ground height smoothing to prevent stumbling on uneven terrain
Movement:
- Fix speed controls: Shift=sprint (28), normal run (14), Ctrl=walk (5)
- Reduce character height for doorway clearance (eye height 1.2)
- Add working crouch (C or X key) with smooth transition (eye height 0.6)
- Jump to stand up from crouch
M2 Animation:
- Add animation time tracking per M2 instance
- Add procedural swaying animation in vertex shader
- Update animation each frame for vegetation movement
