Previously all player spell casts played ARCANE school sounds regardless
of the actual spell school. Now loadSpellNameCache() reads SchoolMask
(bitmask, TBC/WotLK) or SchoolEnum (Vanilla/Classic) from Spell.dbc and
stores it in SpellNameEntry. handleSpellStart/handleSpellGo look up the
spell's school and select the correct MagicSchool for cast sounds.
DBC field indices: WotLK SchoolMask=225 (verified), TBC=215, Classic/Turtle
SchoolEnum=1 (Vanilla enum 0-6 converted to bitmask).
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.
CharSections fields were mapped incorrectly (Variation/Color at 4-5,
textures at 6-8) — corrected to textures at 4-6, Flags at 7,
Variation at 8, Color at 9. Fixed in both dbc_layout.cpp and all
expansion JSON configs. Also fix Warden HASH_REQUEST to SHA1 over
seed+moduleImage instead of just seed.
Binary ItemDisplayInfo.dbc has 23 fields with texture components at
14-21, not 15-22. The previous "fix" shifted all fields by +1 which
read wrong columns and broke both player and NPC equipment rendering.
Also fix local player texture cycling: rebuildOnlineInventory() was
called on every item query response (including for other players),
unconditionally setting onlineEquipDirty_ which triggered redundant
texture recompositing. Now tracks previous equipment displayInfoIds
and only sets dirty when they actually change.
Unified all 3 equipment texture code paths (local player, other
players, NPCs) to use the DBC layout system with correct field 14
base index.
Texture regions are at DBC fields 15-22, not 14-21. Field 14 is
HelmetGeosetVis[1] (uint32), and getString() on it returned random
strings from the DBC string block, causing garbled textures on
players and missing leg textures on other characters.
Cache composite textures by input key so identical NPC equipment
combos share one GPU texture. Use DBC layout system for
ItemDisplayInfo texture component fields instead of hardcoded
indices (cross-expansion support). Selective player equipment
re-emission on item query response instead of broadcasting to
all players.
Two bugs fixed:
1. SMSG_INSPECT_RESULTS (0x115) was falling through to the inspect
handler, but this opcode is not the real inspect response. Removed
the case so only SMSG_INSPECT_TALENT (0x3F4) triggers the handler.
2. EmotesText DBC layout was missing "ID" field in all 4 expansion
JSON files, causing operator[] to return 0xFFFFFFFF instead of 0.
This broke the dbcId reverse lookup, so other players' emotes
always fell back to generic "performs an emote" text. Added ID
and OthersTargetTextID/OthersNoTargetTextID to all layouts.
Expansion overlays allow each expansion to supplement the base asset data
via an assetManifest field in expansion.json, loaded at priority 50 (below
HD packs). The asset extractor gains --reference-manifest for delta-only
extraction. Also fixes CharSections field indices (VariationIndex=4,
ColorIndex=5, Texture1=6) across all DBC layout references.
Replace hardcoded WotLK protocol constants with a data-driven architecture
supporting Classic 1.12.1, TBC 2.4.3, and WotLK 3.3.5a. Each expansion
has JSON profiles for opcodes, update fields, and DBC layouts, plus C++
polymorphic packet parsers for binary format differences (movement flags,
speed fields, transport data, spline format, char enum layout).
Key components:
- ExpansionRegistry: scans Data/expansions/*/expansion.json at startup
- OpcodeTable: logical enum <-> wire values loaded from JSON
- UpdateFieldTable: field indices loaded from JSON per expansion
- DBCLayout: schema-driven DBC field lookups replacing magic numbers
- PacketParsers: WotLK/TBC/Classic parsers with correct flag positions
- Multi-manifest AssetManager: layered manifests with priority ordering
- HDPackManager: overlay texture packs with expansion compatibility
- Auth screen expansion picker replacing hardcoded version dropdown
