Replace 2D screen-space ding rings with real WoW LevelUp.m2 particle/geometry
effect. Fix FBlock particle color parsing (C3Vector floats, not CImVector bytes)
which was producing blue/red instead of golden yellow. Spell effect models bypass
particle dampeners, glow sprite conversion, Mod→Additive blend override, and all
collision (floor/wall/camera) to prevent camera zoom-in. Other players' level-ups
trigger the 3D effect at their position with group chat notification. F7 hotkey
for testing.
Mod blend (GL_DST_COLOR, GL_ZERO) multiplies the framebuffer by texture color,
so dark pixels create visible black rectangles. Use a variable colorKeyThreshold
uniform (0.7 for Mod/Mod2x, 0.08 default) to discard dark pixels from these
batches while preserving normal colorKeyBlack behavior elsewhere.
The pixel content glow detection (>60% dark = glow) was too aggressive,
flagging dark metal textures on sconces as glow textures and making
structural geometry transparent. The forced additive blending for
colorKeyBlack batches compounded the issue.
Reverted both. Added per-batch diagnostic logging for models containing
"light", "lamp", or "lantern" to identify the actual blend modes and
material flags on Stormwind bridge lamps.
force additive blending for colorKeyBlack batches
Two key changes:
1. Detect glow-like textures by analyzing pixel content during loading:
textures that are >60% near-black with some bright pixels are flagged
as colorKeyBlack regardless of filename. This catches glow textures
like Stormwind street lamps whose paths don't contain keywords like
"lamp" or "lantern".
2. Force additive blending (mode 3) for batches with colorKeyBlack
textures that have blendMode 1 or 2. These textures are designed for
additive blending where black = transparent, but some M2 files specify
Alpha or AlphaKey blend modes which cause black areas to render as
solid dark disks instead of being invisible.
Two fixes:
1. shouldUseGlowSprite now requires the UNLIT material flag (0x01) for
the colorKeyBlack+flameLikeModel path. Previously, structural geometry
(torch handles, sconce brackets) on flame-like models got replaced
with glow sprites because their texture paths contained keywords like
"torch" in the directory name, setting colorKeyBlack on non-glow
textures. Requiring UNLIT ensures only actual glow/emissive batches
become sprites while lit structural geometry renders normally.
2. Fragment shader now discards near-black (maxRGB < 0.1) for ALL unlit
non-opaque batches, not just additive blend modes. Glow effects on
lanterns/lamps that use blendMode 1 (AlphaKey) or 2 (Alpha) instead
of 3 (Additive) now properly discard their black backgrounds.
Three-part fix for glow textures showing opaque black rectangles instead
of being transparent:
1. Pass blend mode to fragment shader via uBlendMode uniform. For additive
blend modes (3=Add, 6=BlendAdd), discard near-black fragments (maxRGB
< 0.1) since they contribute nothing visually but render as dark
rectangles against sky/terrain.
2. Expand colorKeyBlack texture keyword detection to include "lamp",
"lantern", "glow", "flare", "brazier", "campfire", "bonfire" in
addition to the existing "candle", "flame", "fire", "torch".
3. Expand flameLikeModel detection for glow sprite conversion to include
"brazier", "campfire", "bonfire". Also compute glow centers for
colorKeyBlack batches (not just blendMode >= 3) so glow sprites
position correctly for all flame-like objects.
Two bugs caused the client to look like a bot to server GMs:
1. Strafe animation played during forward+strafe (W+A) instead of the
walk/run animation. Added pureStrafe guard so strafe animations only
play when exclusively strafing (no forward key or auto-run active).
2. CMSG_MOVE_SET_FACING was never sent on mouse-look turns. The server
predicts movement from the last known facing; without SET_FACING the
heartbeat position appeared to teleport each time the player changed
direction. Now sent at up to 10 Hz whenever facing changes >3°,
skipped while keyboard-turning (handled server-side by TURN flags).
Both passes were rendering the entire loaded scene (17×17 tile radius)
into a shadow map that only covers 360×360 world units — submitting
10-50× more geometry than the shadow frustum can actually use.
- TerrainRenderer::renderShadow: skip chunks whose bounding sphere
doesn't overlap the shadow frustum AABB in XY. Reduces terrain draw
calls from O(all loaded chunks) to O(chunks within ~180 units).
- M2Renderer::renderShadow: skip instances whose world AABB doesn't
overlap the shadow frustum in XY. Reduces M2 draw calls similarly.
- Both functions now take shadowCenter + halfExtent parameters.
- SHADOW_MAP_SIZE 2048→1024: 4x fewer pixels rasterized in depth pass
- Replace 9-tap manual PCF loop with single hardware PCF tap in all 4 receiver
shaders (terrain.frag, wmo_renderer, m2_renderer, character_renderer).
GL_LINEAR + GL_COMPARE_REF_TO_TEXTURE already gives 2×2 bilinear PCF per
tap for free, so quality is maintained while doing 9x fewer texture fetches.
- Throttle shadow depth pass to every 2 frames; OpenGL depth texture persists
between frames so receivers always have a valid shadow map. 1-frame lag at
60 fps is invisible.
- game_handler.cpp: use-after-move on node.id after std::move(node)
(save nodeId before the move)
- tcp_socket.cpp, world_socket.cpp: virtual call in destructor bypasses
dispatch; use qualified TCPSocket::disconnect() / WorldSocket::disconnect()
to make intent explicit
- wmo_renderer.cpp: float loop counters risk precision drift; replace with
integer step counts and reconstruct float from index
- game_screen.cpp: (float + 0.5) cast to int is incorrect rounding;
use std::lround instead
- choose run only when movement speed is above threshold
- prefer walk for duration-less synthesized movement deltas
- keep animation fallback behavior when specific sequence is unavailable
- use movement animation (prefer run, fallback walk) for server-driven creature moves
- synthesize short movement duration for duration-less movement deltas to avoid glide/attack-pose sliding
- return to idle after both walk/run movement states
- drive target circle from entity latest position and always interpolate selected/engaged targets
Batches whose named texture fails to load now render invisible instead of
white (the swampreeds01a.blp case causing a white shell around aquatic plants).
Also implements proper M2 opacity plumbing:
- Parse texture weight tracks (M2Track<fixed16>) and color animation alpha
tracks (M2Color.alpha) to resolve per-batch opacity at load time
- Skip batches with batchOpacity < 0.01 in the render loop
- Apply M2Texture.flags (bit0=WrapS, bit1=WrapT) to GL sampler wrap mode
- Upload both UV sets (texCoords[0] and texCoords[1]) and select via
textureUnit uniform, so batches referencing UV set 1 render correctly
Add AssetManager hookup to AudioEngine so the path-based playSound2D/3D
overloads can load files on demand rather than requiring preloading.
- Add setAssetManager() to AudioEngine (called during world load alongside
other audio manager initializations)
- playSound2D(mpqPath) now calls assetManager->readFile() then delegates
to the vector<uint8_t> overload (removes the "not yet implemented" warning)
- playSound3D(mpqPath, position) same — delegates to the fully spatialized
vector overload (was previously silently falling back to 2D)
- Add TurtlePacketParsers with dedicated movement block parser (Classic format + transport timestamp)
- Fix quest giver status: read uint32 and translate vanilla enum values for Classic/Turtle
- Fix quest accept packet: remove trailing uint32 that vanilla servers reject
- Fix quest details parser: auto-detect vanilla vs WotLK format (informUnit field)
- Fix spellbook and action bar icons: fallback to WotLK DBC field indices when expansion layout fails
- Fix spell cast failure messages: translate vanilla SpellCastResult codes (+1 offset)
- Fix realm list: correct type values (6=RP, 8=RP-PvP) and population thresholds
- Fix music: disable looping for zone music, auto-advance to next random track when finished
- Add music anti-repeat: avoid playing the same track back-to-back
- Make TBC update block parsing resilient (keep parsed blocks on failure instead of aborting)
- Add right-click attack on hostile mobs
- Add name query diagnostic logging
The binary DBC files for all expansions use the same field ordering
(VariationIndex=4, ColorIndex=5, Texture1=6), but classic/tbc/turtle
dbc_layouts.json had swapped texture and variation/color fields, causing
all skin/face/hair/underwear lookups to fail. Also adds generalized
NxN texture scaling and a second video to README.
- 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
Use FlyForward/FlyIdle animations (IDs 158/159) for taxi mounts instead
of ground movement animations (Stand/Run). Add detailed mount texture
debug logging and improve fallback texture resolution for gryphon/wyvern
models with multiple skin slots.
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.
M2 models like OrgrimmarFloatingEmbers and OrgrimmarSmokeEmitter have a
simple box mesh (24 verts, 36 indices) meant only to define particle
emitter bounds. Their blendMode was 0 (opaque), causing them to render
as large grey boxes. Detect these by checking for box geometry with
particle emitters and large bounds (>5 units), then mark as invisible.
Also add ANTIPORTAL and batch-disable flag checks to WMO group filtering.
- Fix FBlock color keys from 3-byte BGR to 4-byte RGBA (CImVector) to
prevent garbled purple/red colors from byte misalignment
- Add circular soft-edge falloff in particle fragment shader (GL_POINTS
rendered as squares by default)
- Apply default gravity (4.0 spray, 1.5 mist) when M2 gravity is 0 since
bone animation from .anim files isn't loaded yet
- Add drift velocity to speed=0 emitters so particles spread as mist
instead of clustering at static bone positions
- Run particle updates for all nearby instances, not just those in
boneWorkIndices_, to prevent particles freezing when bone culled
- Wrap animation time for particle models to keep emission tracks looping
- Cap particle scale to 1.5 and reduce point size multiplier (800→400)
- Desaturate FBlock colors 70% toward white for natural water appearance
- Reduce additive blend alpha to 5% and volume particles to 2%
clearCompositeCache() now only clears the lookup map without deleting
GPU textures, preventing NPC and other instance textures from being
accidentally destroyed during player equipment changes.
Corrected CharGeosets group assignments verified via vertex bounding boxes:
- Group 4 (401+) = gloves/forearms, Group 5 (501+) = boots/shins,
Group 8 (801+) = sleeves (chest-controlled), Group 9 = kneepads,
Group 13 (1301+) = pants/trousers, Group 20 (2002) = bare feet
- Changed bare shin default from 501 to 502 for better width match
with thigh mesh (0.39 vs 0.32, thighs are 0.42)
- Added clearCompositeCache() to prevent stale composite textures
from being reused across equipment changes
- Fixed character preview geoset defaults to match corrected mapping
Implement full mail send/receive: SMSG_SHOW_MAILBOX, CMSG_GET_MAIL_LIST,
SMSG_MAIL_LIST_RESULT, CMSG_SEND_MAIL, SMSG_SEND_MAIL_RESULT, mail take
money/item/delete/mark-as-read, and inbox/compose UI windows.
Fix periodic stuttering in Stormwind caused by synchronous per-line disk
flushes in the logger — remove fileStream.flush() and std::endl, downgrade
high-volume per-packet/per-model/per-texture LOG_INFO to LOG_DEBUG.
Use authoritative WoW Model Viewer atlas coordinates (256x256 reference)
for face, underwear, and body region placement. Previously all coordinates
were hardcoded at 512x512 scale causing overlays to be clipped on the
256x256 base skin. Also include face upper+lower textures from
CharSections.dbc in compositing for both player and other-player characters.
Fix 9 PopStyleVar(2) calls that should be PopStyleVar(1) across
player frame, target frame, cast bar, party frames, buff bar, escape
menu, death dialog, and resurrect dialog. Fix action bar from
PopStyleVar(2) to PopStyleVar(4) to match 4 pushes.
Fix character geoset defaults: 301→302 (bare hands), 701→702 (ears),
1501→1502 (back/cloak), add 802 (wristbands). No WoW character model
uses geoset 301/701/1501; all use 302/702/1502 as base. This fixes
missing hands/arms on undead and other races with separate hand meshes.
11 original tracks in assets/Original Music/ now play on the login
screen and in thematically matched zones across Eastern Kingdoms and
Kalimdor. Added crossfadeToFile to MusicManager for local file
playback during zone transitions. New zones: Tirisfal, Undercity,
Barrens, STV, Duskwood, Burning Steppes, Searing Gorge, Ironforge,
Loch Modan, Orgrimmar, Durotar, Mulgore, Thunder Bluff, Darkshore,
Teldrassil, Darnassus.
- Skip WMO batches with material flags F_SIDN (0x20) or F_WINDOW (0x40)
which are transparent sky/window panes that render as grey curtains
- Fix /unstuck: always nudge 5 units forward first, then sample floor at
destination instead of teleporting back to last safe position (which
could be the stuck location itself)
The previous fix only skipped groups where ALL batches were untextured.
Groups with a mix of textured and untextured batches still rendered the
untextured ones as solid grey geometry. Now skip each untextured batch
individually during rendering.
- Per-family mount sounds (kodo, tallstrider, mechanostrider, etc.) detected from M2 model path
- Skip WMO groups with SHOW_SKYBOX flag or all-untextured batches (grey mesh in Orgrimmar)
- Freeze physics during taxi landing until terrain loads to prevent falling through void
- Disable bone animations on tropical vegetation (palm, bamboo, banana, etc.) to fix wiggling
- Snap player to final taxi waypoint on flight completion
- Extract mount aura spell ID from classic UNIT_FIELD_AURAS for CMSG_CANCEL_AURA dismount
- Increase /unstuck forward nudge to 5 units
- Parse MCLQ sub-chunks in vanilla ADTs for water rendering (WotLK uses MH2O)
- Load TaxiPathNode.dbc for MO_TRANSPORT world-coordinate paths (vanilla boats)
- Parse data[] from SMSG_GAMEOBJECT_QUERY_RESPONSE (taxiPathId for transports)
- Support vanilla M2 particle emitters (504-byte struct, different from WotLK 476)
- Add character preview texture diagnostic logging
- Fix disconnect handling on character screen (show error only when no chars)
