TBC 2.4.3 SMSG_ITEM_QUERY_SINGLE_RESPONSE differs from WotLK: no Flags2,
no BuyCount, statsCount-many stat pairs (not always 10), and no
ScalingStatDistribution/ScalingStatValue. Without this override,
TbcPacketParsers fell back to the WotLK parser and misread stats/armor
with a cascading 16-byte offset. Classic (Vanilla) was already safe via
its own independent ClassicPacketParsers::parseItemQueryResponse().
- 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
Vanilla CMSG_ITEM_QUERY_SINGLE has no GUID field (just uint32 entry),
causing servers to reject the oversized WotLK-format packets. Also fix
response parser: remove nonexistent statsCount field and use 5 damage
types instead of 2 to match Vanilla protocol.
Rebuild creature display lookups after expansion-specific DBC layout loads
(was using WotLK defaults before turtle layout was available). Add full
drag-and-drop support for bag items with server-side CMSG_SWAP_ITEM packets.
Add Classic-specific SMSG_ITEM_QUERY_SINGLE_RESPONSE parser for Vanilla
format differences (fewer damage types, no scaling stats, no Flags2).
Fix mailbox right-click (transposed CMSG_GAMEOBJECT_USE opcode, missing
mail opcodes in Turtle WoW JSON, decorative GO type filtering). Add
expansion-aware mail packet handling via PacketParsers: Classic format
(single item, no msgSize prefix, Vanilla field order) vs WotLK format
(attachment arrays, enchant slots). Fix CMSG_MAIL_TAKE_ITEM and
CMSG_MAIL_DELETE for Vanilla (no trailing fields). Add pulsing "New
Mail" indicator below minimap, SMSG_RECEIVED_MAIL and
MSG_QUERY_NEXT_MAIL_TIME handlers, and async sender name backfill.
SpellCastTargets target mask is uint16 in vanilla 1.12.x, not uint32
like WotLK. The 2 extra bytes corrupted every spell packet. Also add
classic CMSG_USE_ITEM builder (bag+slot+spellIndex+targets only, no
spellId/itemGuid/glyphIndex/castFlags fields that WotLK added).
- 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)
Classic gossip packets lack the menuId field and quest items don't have
questFlags/isRepeatable, causing the WotLK parser to read garbage counts
(541M quests) and hang. Added ClassicPacketParsers::parseGossipMessage
override with the correct vanilla format.
Fix WotLK chat parser not stripping null terminators from messages,
fix channel message local echo missing channelName, expand default
channels to General/Trade/LocalDefense/LookingForGroup with
configurable auto-join, add Classic packet format for join/leave
channel, display channel index prefix in chat, and add Chat settings
tab with timestamps, font size, and auto-join toggles.
Three Classic packet format fixes:
1. CMSG_CAST_SPELL: target flags are uint32 (not uint16). The wrong
size caused the server to misparse the packet as an item enchant
operation, returning "item already enchanted".
2. SMSG_CAST_FAILED: Classic has no castCount byte prefix (added in
TBC). Added parseCastFailed override to ClassicPacketParsers.
Without this, the parser read the wrong bytes and produced
"Spell cast failed (error 0)" for every failure.
3. SMSG_MESSAGECHAT: Removed spurious receiverGuid read for SAY/YELL
types. Classic chat format has no second GUID before the message
body — the extra 8-byte read consumed messageLen + message data,
producing empty chat messages.
Vanilla CMSG_CAST_SPELL target mask is uint16 (not uint32 like WotLK),
the extra 2 bytes were corrupting packets. Also implement full bag
content tracking: extract container slot GUIDs from CONTAINER update
objects, set proper bag sizes, and populate bag items in inventory
rebuild.
- Parse vanilla M2 animation tracks (flat arrays with M2Range indices)
instead of skipping them, fixing T-pose on all vanilla models
- Use C4Quaternion (float[4]) for vanilla bone rotations instead of
CompressedQuat (int16[4]) which produced garbage transforms
- Fix vanilla M2 attachment struct size (48 bytes, not 40) so weapons
attach to correct bones instead of model origin
- Route movement packets through expansion-specific packet parsers
instead of hardcoded WotLK format, fixing server-side position sync
- Fix Spell.dbc field indices for classic/turtle (Name=120, Rank=129,
IconID=117) - were pointing to Portuguese locale column (+7 offset)
- Change guild roster keybind from J to O (WoW default)
- Add guild opcodes for all expansions
- Route SMSG_UPDATE_OBJECT through polymorphic parsers for correct
vanilla format (uint8 updateFlags, 6 speeds vs WotLK uint16/9)
- Fix SMSG_DESTROY_OBJECT for vanilla (8 bytes, no isDeath field)
- Add MSG_MOVE_* handlers for other player movement relay
- Add ClassicPacketParsers::parseMessageChat with targetGuid read
and monster-type name handling
- Resolve chat sender names from player name cache before display
- Fix CSV DBC field 0 always treated as numeric ID (fixes 16+ garbled
Turtle CSVs including Map, AreaTable, Spell, CreatureDisplayInfo)
- Add CSV DBC validation: reject garbled CSVs (>80% zero IDs) and
fall back to binary DBC files
- Fix ItemDisplayInfo texture component field index (14+ not 15+)
for binary DBC with gender-aware suffix resolution
- Spawn other players as visible M2 models via creature callback
- Map name cache dedup prevents overwrites from duplicate CSV records
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
