The character stats panel was showing Armor: 0 because summing armor
from item query responses is fragile (depends on correct BuyCount/damage
block parsing). Instead, read the server-authoritative total armor
directly from UNIT_FIELD_RESISTANCES (physical resistance, index 0)
in the player entity update fields.
Added UNIT_FIELD_RESISTANCES to the UF enum and all four expansion
JSON files with correct wire indices:
WotLK 3.3.5a: 99 (NPC_FLAGS=82 + emotestate + stat×5 + posstat×5 + negstat×5)
TBC 2.4.3: 185 (NPC_FLAGS=168 + same relative layout)
Classic 1.12: 154 (NPC_FLAGS=147 + emotestate + stat×5, no posstat/negstat)
Turtle WoW: 154 (same as Classic)
Stats panel uses server armor when > 0, falls back to summed item-query
armor otherwise. Armor rating resets to 0 on world entry and is updated
from both CREATE_OBJECT and VALUES update blocks.
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.
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
