Kelsi 644cfcc8c1 fix(update-fields): correct multiple wrong vanilla 1.12 indices on classic/turtle 
The classic and turtle update_fields.json files had several wrong
indices that aliased fields together and misread the unit record.
Cross-referenced vmangos UpdateFields_1_12_1.h
(github.com/vmangos/core, OBJECT_END=6) and corrected:

- UNIT_FIELD_BYTES_1:        133 -> 138 (was colliding with MOUNTDISPLAYID)
- UNIT_FIELD_STAT0..STAT4:   138..142 -> 150..154 (the old slot held
                              pet fields PETNUMBER/PET_NAME_TIMESTAMP/
                              PETEXPERIENCE/PETNEXTLEVELEXP, not stats)
- UNIT_FIELD_RESISTANCES:    154 -> 155 (off by one — STAT4 lives at 154)
- UNIT_FIELD_NATIVEDISPLAYID: added (was missing) -> 132

The verified other indices (DISPLAYID=131, MOUNTDISPLAYID=133,
DYNAMIC_FLAGS=143, NPC_FLAGS=147, BYTES_0=36) all matched vmangos
and were left alone.

Practical impact on Classic/Turtle prior to this fix:
- entity_controller.cpp:548-553 read MOUNTDISPLAYID and BYTES_1 from
  the same slot — mount/dismount detection and shapeshift form
  detection would race and clobber each other.
- All STAT* readers were reading pet-related fields instead of stats,
  so character-sheet stats and stat-derived UI on Classic/Turtle
  would be wrong/zero.
- UNIT_FIELD_RESISTANCES readers got STAT4 instead of armor resist.

Python collision check after patch: no UNIT_* collisions in either
file.

What This Repo Is

Wowee is a native C++ World of Warcraft client experiment focused on connecting to real emulator servers (online/multiplayer) with a custom renderer and asset pipeline.

Current Code State

Implemented (working in normal use):

  • Auth flow: SRP6a auth + realm list + world connect with header encryption
  • Rendering: terrain, WMO/M2, water/magma/slime (FBM noise shaders), sky system, particles, shadow mapping, minimap/world map, loading video playback
  • Instances: WDT parser, WMO-only dungeon maps, area trigger portals with glow/spin effects, zone transitions
  • Character system: creation (including nonbinary gender), selection, 3D preview with equipment, character screen, per-instance NPC hair/skin textures
  • Core gameplay: movement (with ACK responses), targeting (hostility-filtered tab-cycle), combat, action bar, inventory/equipment, chat (tabs/channels, emotes, item links)
  • Quests: quest markers (! and ?) on NPCs/minimap, quest log with detail queries/retry, objective tracking, accept/complete flow, turn-in, quest item progress
  • Trainers: spell trainer UI, buy spells, known/available/unavailable states
  • Vendors, loot (including chest/gameobject loot), gossip dialogs (including buyback for most recently sold item)
  • Bank: full bank support for all expansions, bag slots, drag-drop, right-click deposit
  • Auction house: search with filters, pagination, sell picker, bid/buyout, tooltips
  • Mail: item attachment support for sending
  • Spellbook with specialty/general/profession/mount/companion tabs, drag-drop to action bar, spell icons, item use
  • Talent tree UI with proper visuals and functionality
  • Pet tracking (SMSG_PET_SPELLS), dismiss pet button
  • Party: group invites, party list, out-of-range member health (SMSG_PARTY_MEMBER_STATS)
  • Nameplates: NPC subtitles, guild names, elite/boss/rare borders, quest/raid indicators, cast bars, debuff dots
  • Floating combat text: world-space damage/heal numbers above entities with 3D projection
  • Target/focus frames: guild name, creature type, rank badges, combo points, cast bars
  • Map exploration: subzone-level fog-of-war reveal
  • Warden anti-cheat: full module execution via Unicorn Engine x86 emulation; module caching
  • Audio: ambient, movement, combat, spell, and UI sound systems; NPC voice lines for all playable races (greeting/farewell/vendor/pissed/aggro/flee)
  • Bag UI: independent bag windows (any bag closable independently), open-bag indicator on bag bar, server-synced bag sort, off-screen position reset, optional collapse-empty mode in aggregate view
  • DBC auto-detection: CharSections.dbc field layout auto-detected at runtime (handles stock WotLK vs HD-textured clients)
  • Multi-expansion: Classic/Vanilla, TBC, WotLK, and Turtle WoW (1.18) protocol and asset variants
  • CI: GitHub Actions for Linux (x86-64, ARM64), Windows (MSYS2 x86-64 + ARM64), macOS (ARM64); container builds via Podman

Recent refactors (PRs #59-63, April 2026):

  • Chat system decomposed into 15+ modules under src/ui/chat/ with 11 command modules, GM command support, macro evaluator, and tab completion
  • World map decomposed into 16 modules under src/rendering/world_map/ with overlay layer system, view state machine, and ZMP-based hover detection
  • TransportManager decomposed: spline math extracted to src/math/, path data to TransportPathRepository, 7 duplicated spline parsers consolidated into spline_packet.cpp
  • Spell visual effects system with bone-tracked ribbons and particles
  • Entity movement improvements: multi-segment path interpolation, terrain height clamping, walk/run animation fix
  • 31 unit-test suites (up from 8), covering chat, world map, spline math, transport, and animation systems
  • Code quality fix pass: 7 issues resolved across hover detection, null safety, buffer bounds, and coordinate validation

In progress / known gaps:

  • World map: zone hover detection has edge cases with some zone boundaries; cosmic highlight sizing is approximate
  • Transports: M2 transports (trams) working with position-delta riding; WMO transports (ships, zeppelins) working with path following; some edge cases remain
  • Quest GO interaction: CMSG_GAMEOBJ_USE + CMSG_LOOT sent correctly, but some AzerothCore/ChromieCraft servers don't grant quest credit for chest-type GOs (server-side limitation)
  • Visual edge cases: some M2/WMO rendering gaps (some particle effects)
  • Water refraction: enabled by default; srcAccessMask barrier fix (2026-03-18) resolved prior VK_ERROR_DEVICE_LOST on AMD/Mali GPUs
  • Fixed 2026-05-15: classic/turtle update-field tables had multiple wrong indices (UNIT_FIELD_BYTES_1=133 colliding with UNIT_FIELD_MOUNTDISPLAYID=133; STAT0..4 at 138..142; RESISTANCES at 154; missing NATIVEDISPLAYID). Corrected against vmangos UpdateFields_1_12_1.h: BYTES_1=138, STAT0..4=150..154, RESISTANCES=155, added NATIVEDISPLAYID=132.

Where To Look

  • Entry point: src/main.cpp, src/core/application.cpp
  • Networking/auth: src/auth/, src/network/, src/game/game_handler.cpp
  • Rendering: src/rendering/
  • Assets/extraction: extract_assets.sh, tools/asset_extract/, src/pipeline/asset_manager.cpp
