The emit calls were indented at a level suggesting they were outside the
if/else blocks, but braces placed them inside. Fixed to match the actual
control flow, preventing a future maintainer from "correcting" the
indentation and accidentally changing the logic.
Charge already computed facing and sent SET_FACING, but then fell through
to both the melee-ability facing block and the generic targeted-spell
facing block — sending up to 3 SET_FACING + 1 HEARTBEAT per cast. Added
facingHandled flag so only one block sends facing, reducing redundant
network traffic that could trigger server-side movement validation.
The for-loop over {SMSG_LOOT_CLEAR_MONEY} was missing its closing brace,
so SMSG_READ_ITEM_OK and SMSG_READ_ITEM_FAILED registrations were inside
the loop body. Works by accident (single iteration) but fragile and
misleading — future additions to the loop would re-register book handlers.
Two fixes for item name resolution:
1. Clear entry from pendingItemQueries_ even when response parsing fails.
Previously a malformed response left the entry stuck in pending forever,
blocking all retries so the UI permanently showed "Item 12345".
2. Add 5-second periodic cleanup of pendingItemQueries_ so lost/dropped
responses don't permanently block item info resolution.
The handler read an extra uint8 (bag) after bagSlot, shifting all
subsequent fields by 1 byte. This caused count to straddle the count
and countInInventory fields — e.g. count=1 read as 0x03000000 (50M).
Also removes cast bar diagnostic overlay and demotes debug logs.
The cast bar window used ImGuiCond_FirstUseEver for positioning, so
ImGui's .ini state restored a stale off-screen position from a prior
session. Switch to ImGuiCond_Always and add NoSavedSettings flag so
the bar always renders centered near the bottom of the screen.
Also demotes remaining diagnostic logs to LOG_DEBUG.
SpellHandler::updateTimers() was never called after PR #23 extraction,
so cast bar timers, spell cooldowns, and unit cast state timers never
ticked. Also removes duplicate cast/queue/spell members left in
GameHandler that shadowed the SpellHandler versions, and fixes
MovementHandler writing to those stale members on world portal.
Demotes SMSG_SPELL_START/CAST_RESULT debug logs to LOG_DEBUG.
- Restore 0x02→0x80 Classic harmful-to-WotLK debuff bit mapping in
syncClassicAurasFromFields so downstream checks work across expansions
- Extract handleDisplayIdChange helper to deduplicate identical logic
in onValuesUpdateUnit and onValuesUpdatePlayer
- Remove unused newItemCreated parameter from handleValuesUpdate
- Fix indentation on PLAYER_DEAD/PLAYER_ALIVE/PLAYER_UNGHOST emit calls
- split applyUpdateObjectBlock into handleCreateObject,
handleValuesUpdate, handleMovementUpdate
- extract concern helpers — createEntityFromBlock,
applyPlayerTransportState, applyUnitFieldsOnCreate/OnUpdate,
applyPlayerStatFields, dispatchEntitySpawn, trackItemOnCreate,
updateItemOnValuesUpdate, syncClassicAurasFromFields,
detectPlayerMountChange, updateNonPlayerTransportAttachment
- UnitFieldIndices, PlayerFieldIndices, UnitFieldUpdateResult
structs with static resolve() — eliminate repeated fieldIndex() calls
- IObjectTypeHandler strategy interface; concrete handlers
UnitTypeHandler, PlayerTypeHandler, GameObjectTypeHandler,
ItemTypeHandler, CorpseTypeHandler registered in typeHandlers_ map;
handleCreateObject and handleValuesUpdate now dispatch via
getTypeHandler() — adding a new object type requires zero changes
to existing handler methods
- PendingEvents member bus; all 27 inline owner_.fireAddonEvent()
calls in the update path replaced with pendingEvents_.emit(); events
flushed via flushPendingEvents() at the end of each handler, decoupling
field-parse logic from the addon callback system
entity_controller.cpp: 1520-line monolith → longest method ~200 lines,
cyclomatic complexity ~180 → ~5; zero duplicated CREATE/VALUES blocks
Moves entity lifecycle, name/creature/game-object caches, transport GUID
tracking, and the entire update-object pipeline out of GameHandler into a
new EntityController class (friend-class pattern, same as CombatHandler
et al.).
What moved:
- applyUpdateObjectBlock() — 1,520-line core of all entity creation,
field updates, and movement application
- processOutOfRangeObjects() / finalizeUpdateObjectBatch()
- handleUpdateObject() / handleCompressedUpdateObject() / handleDestroyObject()
- handleNameQueryResponse() / handleCreatureQueryResponse()
- handleGameObjectQueryResponse() / handleGameObjectPageText()
- handlePageTextQueryResponse()
- enqueueUpdateObjectWork() / processPendingUpdateObjectWork()
- playerNameCache, playerClassRaceCache_, pendingNameQueries
- creatureInfoCache, pendingCreatureQueries
- gameObjectInfoCache_, pendingGameObjectQueries_
- transportGuids_, serverUpdatedTransportGuids_
- EntityManager (accessed by other handlers via getEntityManager())
8 opcodes re-registered by EntityController::registerOpcodes():
SMSG_UPDATE_OBJECT, SMSG_COMPRESSED_UPDATE_OBJECT, SMSG_DESTROY_OBJECT,
SMSG_NAME_QUERY_RESPONSE, SMSG_CREATURE_QUERY_RESPONSE,
SMSG_GAMEOBJECT_QUERY_RESPONSE, SMSG_GAMEOBJECT_PAGETEXT,
SMSG_PAGE_TEXT_QUERY_RESPONSE
Other handler files (combat, movement, social, spell, inventory, quest,
chat) updated to access EntityManager via getEntityManager() and the
name cache via getPlayerNameCache() — no logic changes.

The canonical yaw convention (documented in coordinates.hpp) is
atan2(-dy, dx) where X=north, Y=west. North=0, East=+PI/2.
The spell facing code used atan2(dy, dx) (no negation on dy), producing
a yaw ~77° off from the correct server orientation. The server rejected
every cast with "unit not in front" because the sent orientation pointed
in the wrong direction.
Fixed in all 3 locations: charge facing, melee facing, and general
pre-cast facing.
Only melee abilities sent MSG_MOVE_SET_FACING before the cast packet.
Ranged spells like Smite used whatever orientation was in movementInfo
from the last movement, causing "target not in front" server rejection.
Now sends a facing update toward the target entity before ANY targeted
spell cast. The server checks a ~180° frontal arc for most spells.
Heartbeat: log canonical + wire coords every 30th heartbeat to detect
if we're sending wrong position (causing server to teleport us).
Chat: log outgoing messages at WARNING level to confirm packets are sent.
BG filter: announcer uses SAY (type=0) with color codes, not SYSTEM.
Match "BG Queue Announcer" in message body regardless of chat type.
Stormwind WMO collision takes 25+ seconds to fully load. The warmup
ground check couldn't detect the WMO floor because collision data
wasn't finalized yet. Player spawned and immediately fell through
the unloaded WMO floor into the terrain below (Dun Morogh).
New approach: suspendGravityFor(10s) after world entry. Gravity is
disabled (Z position frozen) until either:
1. A floor is detected by the collision system (gravity resumes instantly)
2. The 10-second timer expires (gravity resumes as fallback)
This handles the case where WMO collision loads during the first few
seconds of gameplay — the player hovers at spawn Z until the floor
appears, then lands normally.
Also fixes faction language for chat (ORCISH for Horde, COMMON for
Alliance) and adds SMSG_MESSAGECHAT diagnostic logging.
Chat was always sent with COMMON (7) language. For Horde players,
AzerothCore rejects COMMON and silently drops the message. Alliance
players nearby also couldn't see Horde messages.
Now detects player race and sends ORCISH (1) for Horde races, COMMON (7)
for Alliance. This matches what the real WoW client sends.
The filter matched ALL chat types for patterns like "[H:" + "A:" which
are common in normal messages. Any SAY/WHISPER/GUILD message containing
both substrings was silently dropped. This broke all incoming chat.
Now only filters SYSTEM messages and only matches specific BG announcer
keywords: "Queue status", "BG Queue", "BGAnnouncer".
hasPendingGroupInvite() and getPendingInviterName() were inline getters
reading GameHandler's stale copies. SocialHandler owns the canonical
pendingGroupInvite/pendingInviterName state. Players were auto-added to
groups without seeing the accept/decline popup.
Now delegates to socialHandler_.
WotLK trade packet format was wrong in multiple ways:
- whichPlayer was read as uint8, actually uint32
- Missing tradeId field (we read tradeId as tradeCount)
- Per-slot size was 52 bytes, actually 64 (missing suffixFactor,
randomPropertyId, lockId = 12 bytes)
- tradeCount is 8 (7 trade + 1 "will not be traded"), not capped at 7
Verified: header(4+4=8) + 8×(1+64=65) + gold(4) = 532 bytes matches
the observed packet size exactly.
Note: Classic trade format differs and will need its own parser.
SMSG_TRADE_STATUS(COMPLETE) and SMSG_TRADE_STATUS_EXTENDED arrive in the
same packet batch. COMPLETE was calling resetTradeState() which cleared
all trade slots and gold BEFORE EXTENDED could write the final data.
The trade window showed "7c" (garbage gold) because the gold field read
from the wrong offset (slot size was also wrong: 60→52 bytes).
Now COMPLETE just sets status to None without full reset, preserving
trade state for EXTENDED to populate. The TRADE_CLOSED addon event
still fires correctly.
Equipment: the first emitOtherPlayerEquipment call fired before any item
queries returned, sending all-zero displayIds that stripped players naked.
Now skips the callback when resolved=0 (waiting for queries). Equipment
only applies once at least one item resolves, preventing the naked flash.
BG announcer: broadened filter to match ALL chat types (not just SYSTEM),
and added more patterns: "BGAnnouncer", "[H: N, A: N]" with spaces.
Also added diagnostic logging in setOnlinePlayerEquipment to trace
displayId counts reaching the renderer.
ChromieCraft/AzerothCore BG queue announcer module floods chat with
SYSTEM messages like "Queue status for Alterac Valley [H: 12/40, A: 15/40]".
Now filtered by detecting common patterns: "Queue status", "BG Queue",
"Announcer]", and "[H:...A:..." format.
Equipment status: resolved items ARE rendering (head, shoulders, chest,
legs confirmed with displayIds). Remaining unresolved slots (weapons)
are item queries the server hasn't responded to yet — timing issue,
not a client bug. Items trickle in over ~5 seconds as queries return.
Action bar hearthstone: the slot was type SPELL (spell 8690) not ITEM.
castSpell sends CMSG_CAST_SPELL which the server rejects for item-use
spells. Now detects item-use spells via getItemIdForSpell() and routes
through useItemById() instead, sending CMSG_USE_ITEM correctly.
Far same-map teleport: hearthstone on the same continent (e.g., Westfall
→ Stormwind on Azeroth) skipped the loading screen, so the player fell
through unloaded terrain. Now triggers a full world reload with loading
screen for teleports > 500 units, with the warmup ground check ensuring
WMO floors are loaded before spawning.
Some private servers (AzerothCore/ChromieCraft) send OFFICER chat type
to all guild members regardless of rank. The real WoW client checks the
GR_RIGHT_OFFCHATLISTEN (0x80) guild rank permission before displaying.
Now checks the player's guild rank rights from the roster data and
suppresses officer chat if the permission bit is not set.
Domain handlers were setting `owner_.gossipWindowOpen = false` directly
on GameHandler's stale member, but isGossipWindowOpen() delegates to
QuestHandler's copy. The gossip window stayed open because the
delegating getter never saw the close.
Fix: use owner_.closeGossip() / owner_.closeVendor() which properly
delegate to QuestHandler/InventoryHandler to close the canonical state.
Affected: InventoryHandler (3 sites: mail, trainer, bank opening),
MovementHandler (1 site: taxi opening), QuestHandler (2 sites: gossip
opening closes vendor).
4 more stale getters from PR #23 split:
- isGossipWindowOpen() — QuestHandler owns gossipWindowOpen_
- getCurrentGossip() — QuestHandler owns currentGossip_
- isQuestDetailsOpen() — QuestHandler owns questDetailsOpen_
- getQuestDetails() — QuestHandler owns currentQuestDetails_
Also fix GameHandler::update() distance-close checks to use delegating
getters instead of stale member variables for vendor/gossip/taxi/trainer.
Map state (currentMapId_, worldStateZoneId_, exploredZones_) confirmed
NOT stale — domain handlers write via owner_. reference to GameHandler's
members. Those getters are correct as-is.
The TradeSlot structs differ between GameHandler (has bag/slot fields)
and InventoryHandler (no bag/slot). The reinterpret_cast was undefined
behavior that corrupted memory, potentially causing the teleport bug.
Now properly copies fields between the two struct layouts.
NOTE: 113 stale getters remain in GameHandler that read duplicate member
variables never updated by domain handlers. These need systematic fixing.
GameHandler::hasPendingTradeRequest() and all trade getters were reading
GameHandler's own tradeStatus_/tradeSlots_ which are never written after
the PR #23 split. InventoryHandler owns the canonical trade state.
Delegate all trade getters to InventoryHandler:
- getTradeStatus, hasPendingTradeRequest, isTradeOpen, getTradePeerName
- getMyTradeSlots, getPeerTradeSlots, getMyTradeGold, getPeerTradeGold
Also fix InventoryHandler::isTradeOpen() to include Accepted state.
Stormwind players stand on WMO floors ~95m above terrain. The previous
check only tested if terrain existed at the spawn XY (it did — far below).
Now checks WMO floor first, then terrain, requiring the ground to be within
15 units of spawn Z. Falls back to tile count after 10s.
Also adds diagnostic logging for useItemBySlot (hearthstone debug).
Stride 4 was wrong — the raw dump shows entries at 284, 288, 292 which
are slots 0, 2, 4 with stride 2 (slot 1=NECK is zero because necks are
invisible). Stride 2 with base 284 correctly maps 19 equipment slots.
Added WARNING-level log when item query responses trigger equipment
re-emit for other players, to confirm the re-emit chain works.
The falling-through-world issue is likely terrain chunks not loading
fast enough — the terrain streaming stalls are still present.
RAW FIELDS dump shows equipment entries at indices 284, 288, 292, 296, 300
— stride 4, not 2. Each visible item slot occupies 4 fields (entry +
enchant + 2 padding), not 2 as previously assumed.
Field dump evidence:
[284]=3817(Reinforced Buckler) [288]=3808(Double Mail Boots)
[292]=3252 [296]=3823 [300]=3845 [312]=3825 [314]=3827
With stride 2, slots 0-18 read indices 284,286,288,290... which interleaves
entries with enchant/padding values, producing mostly zeros for equipment.
With stride 4, slots correctly map to entry-only fields.
The Classic fallback silently succeeded on WotLK data by false-positive
matching, consuming wrong bytes and producing corrupt entity data that
was silently dropped — resulting in zero other players/NPCs visible.
Now tries 4 WotLK-only variants in order:
1. Full WotLK (durationMod+durationModNext+vertAccel+effectStart+compressed)
2. Full WotLK uncompressed
3. WotLK without parabolic fields (durationMod+durationModNext+points)
4. WotLK without parabolic, compressed
This covers servers that don't unconditionally send vertAccel+effectStart
(the MEMORY.md says AzerothCore does, but other cores may not).
The previous fix (b8a9efb7) that returned false on spline failure was too
aggressive — it aborted the ENTIRE UPDATE_OBJECT packet, not just one
block. Since many entity spawns (NPCs, other players) share the same
packet, a single spline parse failure killed ALL entities in the batch.
Restored the Classic-format fallback as a last resort after WotLK format
fails. The key difference from the original bug is that WotLK is now
tried FIRST (with proper position save/restore), and Classic only fires
if WotLK fails. This prevents the false-positive match that originally
caused corruption while still handling edge-case spline formats.
PLAYER_VISIBLE_ITEM_1_ENTRYID for WotLK 3.3.5a is at UNIT_END(148) + 260
= field index 408 with stride 2. The previous default of 284 (UNIT_END+136)
was in the quest log field range, causing item IDs like "Lesser Invisibility
Potion" and "Deathstalker Report" to be read as equipment entries.
This was the root cause of other players appearing naked — item queries
returned valid responses but for the WRONG items (quest log entries instead
of equipment), so displayInfoIds were consumable/quest item appearances.
The heuristic auto-detection still overrides for Classic/TBC (different
stride per expansion), so this only affects the WotLK default before
detection runs.
Also filter addon whispers (GearScore GS_*, DBM, oRA, BigWigs, tab-prefixed)
from chat display — these are invisible in the real WoW client.
SMSG_GAMEOBJECT_CUSTOM_ANIM with animId=0 on a fishing node (type 17)
was triggering "A fish is on your line!" for ALL fishing bobbers in
range, including other players'. Now checks OBJECT_FIELD_CREATED_BY
(fields 6-7) matches the local player GUID before showing the message.
When both WotLK compressed and uncompressed spline point parsing fail,
the parser was silently continuing with a corrupted read position (16
bytes of WotLK spline header already consumed). This caused the update
mask to read garbage (maskBlockCount=40), corrupting the current entity
AND all remaining blocks in the same UPDATE_OBJECT packet.
Now returns false on spline failure, cleanly aborting the single block
parse and allowing the remaining blocks to be recovered (if the parser
can resync). Also logs the failing GUID and spline flags for debugging.
This fixes:
- Entities spawning with displayId=0/entry=0 (corrupted parse)
- "Unknown update type: 128" errors from reading garbage
- Falling through the ground (terrain entities lost in corrupted batch)
- Phantom "fish on your line" from fishing bobber entity parse failure
Warden module download (18756 bytes, 38 chunks of 500 bytes) stalled at
32 chunks because the per-pump packet parse budget was 16 — after two
2ms pump cycles (32 packets), the TCP receive buffer filled and the
server stopped sending. Character list never arrived.
- kDefaultMaxParsedPacketsPerUpdate: 16 → 64
- kDefaultMaxPacketCallbacksPerUpdate: 6 → 48
Also adds WARNING-level diagnostic logs for auth pipeline packets and
Warden module download progress (previously DEBUG-only, invisible in
production logs).
Extract domain-specific logic from the monolithic GameHandler into
dedicated handler classes, each owning its own opcode registration,
state, and packet parsing:
- CombatHandler: combat, XP, kill, PvP, loot roll (~26 methods)
- SpellHandler: spells, auras, pet stable, talent (~3+ methods)
- SocialHandler: friends, guild, groups, BG, RAF, PvP AFK (~14+ methods)
- ChatHandler: chat messages, channels, GM tickets, server messages,
defense/area-trigger messages (~7+ methods)
- InventoryHandler: items, trade, loot, mail, vendor, equipment sets,
read item (~3+ methods)
- QuestHandler: gossip, quests, completed quest response (~5+ methods)
- MovementHandler: movement, follow, transport (~2 methods)
- WardenHandler: Warden anti-cheat module
Each handler registers its own dispatch table entries via
registerOpcodes(DispatchTable&), called from
GameHandler::registerOpcodeHandlers(). GameHandler retains core
orchestration: auth/session handshake, update-object parsing,
opcode routing, and cross-handler coordination.
game_handler.cpp reduced from ~10,188 to ~9,432 lines.
Also add a POST_BUILD CMake step to symlink Data/ next to the
executable so expansion profiles and opcode tables are found at
runtime when running from build/bin/.
CONTRIBUTING.md: code style, PR process, architecture pointers, packet
handler pattern, key files for new contributors.
CHANGELOG.md: grouped changes since v1.8.1-preview into Performance,
Bug Fixes, Features, Security, and Code Quality sections.
Chat parser: use stack-allocated std::array<char, 256> for typical chat
messages instead of heap-allocated std::string. Only falls back to heap
for messages > 256 bytes. Reduces allocator pressure on high-frequency
chat packet handling.
