On disconnect/reconnect to the same map, entityManager was not cleared
and creatureInstances_ still held old entries from the previous session.
When the server re-sent CREATE_OBJECT for the same GUIDs, the spawn
callback's early-return guard (creatureInstances_.count(guid)) silently
dropped every NPC re-spawn, leaving the world empty.
Fixes:
- disconnect() now calls entityManager.clear() to purge stale entities
- WorldEntryCallback gains a bool isInitialEntry parameter (true on first
login or reconnect, false on in-world teleport/flight landing)
- Same-map optimization path skipped when isInitialEntry=true, so
loadOnlineWorldTerrain runs its full cleanup and properly despawns old
creature/player instances before the server refreshes them
- Load WorldMapArea.dbc lazily on first use to build areaId→name lookup
- /who results now show [Zone Name] alongside level: 'Name - Level 70 [Stormwind City]'
- SMSG_EXPLORATION_EXPERIENCE now shows 'Discovered Elwynn Forest! Gained X experience.'
instead of generic 'Discovered new area!' message when the zone name is available
- Cache is populated once per session and shared across both callsites
Quest kill count tracker in the HUD now resolves creature names from the
cached creature query results and displays them as "Name: x/y" instead
of bare "x/y". The system chat progress message on kill also includes
the creature name when available, matching retail client behavior.
Replace static-local firstSpecReceived with talentsInitialized_ member
variable, reset in handleLoginVerifyWorld alongside other per-session
state. Also clear learnedTalents_, unspentTalentPoints_, and
activeTalentSpec_ at world entry so reconnects and character switches
start from a clean talent state instead of carrying over stale data.
- Track PLAYER_REST_STATE_EXPERIENCE update field for all expansions
(WotLK=636, Classic=718, TBC=928, Turtle=718)
- Set isResting_ flag from SMSG_SET_REST_START packet
- XP bar shows rested bonus as a lighter purple overlay extending
beyond the current fill to (currentXp + restedXp) position
- Tooltip text changes to "%u / %u XP (+%u rested)" when bonus exists
- "zzz" indicator shown at bar right edge while resting
- game: clear pendingNameQueries on player out-of-range and DESTROY_OBJECT so
re-entering players get a fresh name query instead of being silently skipped
- game: add 5s periodic name resync scan that re-queries players with empty names
and no pending query, recovering from dropped CMSG_NAME_QUERY responses
- warden: fix UC_ERR_MAP by moving HEAP_BASE from 0x200000 to 0x20000000; the old
heap [0x200000, 0x1200000) overlapped the module at 0x400000, causing Unicorn to
reject the heap mapping and abort emulator initialisation
- warden: add early overlap check between module and heap regions to catch future
layout bugs at init time
- assets: add loadDBCOptional() which logs at DEBUG level when a DBC is absent,
for files that are not distributed on all expansions
- assets: use loadDBCOptional for Item.dbc (absent on Vanilla 1.12 clients) and
fall back to server-sent itemInfoCache displayInfoId for NPC weapon resolution
setTarget() was not clearing targetAuras, leaving stale buff/debuff
icons from the previous target visible on the buff bar until the server
sent SMSG_AURA_UPDATE_ALL for the new target. Reset all slots to empty
on target change so the display is immediately correct.
handleDestroyObject invoked creatureDespawnCallback_ and
gameObjectDespawnCallback_ but not playerDespawnCallback_ for PLAYER
entities. This caused the CharacterRenderer instance for nearby players
to remain alive after they received a DESTROY_OBJECT packet (e.g. when
they teleported or went out of range via server-forced despawn), leaving
phantom models in the world.
Mirror the same despawn logic used for out-of-range removal: call
playerDespawnCallback_ and clean up the per-player bookkeeping maps so
the renderer cleans up the character instance correctly.
SMSG_GROUP_LIST is a full replacement packet, not a delta. handleGroupList()
was not resetting partyData before parsing, so repeated GROUP_LIST packets
pushed duplicate members onto the existing vector — a 2-player party would
show the same name 5 times if the packet was sent 5 times.
Fix: reset partyData = GroupListData{} before calling GroupListParser::parse().
Also fix player names staying "Unknown" when an entity moves out of range and
comes back: queryPlayerName() now applies the cached name to the new entity
object immediately instead of skipping when the name is already in cache.
This was causing other players' names to appear as unknown after zoning or
crossing render distance boundaries.
Parse the full and single-update variants of MSG_RAID_TARGET_UPDATE to
track which guid carries each of the 8 raid icons (Star/Circle/Diamond/
Triangle/Moon/Square/Cross/Skull). Marks are cleared on world transfer.
The target frame now shows the Unicode symbol for the target's raid mark
in its faction color to the left of the name. Nameplates show the same
symbol to the left of the unit name for all nearby marked units.
Expand action bar from 12 to 24 slots (2 bars × 12). Bar 2 is rendered
above bar 1 and loaded from SMSG_ACTION_BUTTONS slots 12-23. Pressing
Shift+number activates the corresponding bar-2 slot. Drag-and-drop,
cooldown overlays, and tooltips work identically on both bars. Bar 2
fades slightly when all its slots are empty to minimize visual noise.
When a friend goes online, offline, or is added/removed, update the
contacts_ vector in addition to friendsCache. This ensures the Friends
tab in the Social window always reflects the current state without
needing a full SMSG_CONTACT_LIST/SMSG_FRIEND_LIST refresh.
Store structured friend data (online status, level, area, class) that
was previously discarded in handleFriendList/handleContactList. New
ContactEntry struct lives in game_handler.hpp; getContacts() exposes it.
UI: the O-key Social window (formerly guild-only) now has a Friends tab.
- Shows online/offline status dot, name, level, and AFK/DND label
- Pressing O when not in a guild opens Social directly on the Friends tab
- The window title changed from "Guild" to "Social" for accuracy
- Non-guild players no longer get a "not in a guild" rejection on O press
- world_packets.cpp::InitialSpellsParser::parse already logs spell count
at LOG_INFO; remove the duplicate count from handleInitialSpells()
- Downgrade verbose format-detection LOG_INFO to LOG_DEBUG (packet size,
format name, first-10 spell IDs) — these are diagnostic details that
clutter INFO output without adding operational value
queryItemInfo and handleItemQueryResponse fire for every item in
inventory, loot windows, vendor lists, and mail — potentially dozens
of times at login or when any container is opened. Downgrade to
LOG_DEBUG to reduce noise. Also downgrade useItemById search traces
to LOG_DEBUG; the final warning (item not found) stays at LOG_WARNING.
Debug-labeled LOG_INFO calls in handleTrainerList and handleInitialSpells
fire every time the trainer window opens or the player logs in, producing
noisy output that obscures meaningful events.
- handleTrainerList: known spells list dump, hardcoded prerequisite checks
(527/25312), and per-spell detail lines → LOG_DEBUG
Keep one LOG_INFO for the spell count summary (meaningful lifecycle event)
- handleInitialSpells: hardcoded spell presence checks (527/988/1180) →
LOG_DEBUG; replace with a single LOG_INFO for spell count summary
Five movement control response handlers (speed change, move-root, move-flag
change, knock-back, teleport) had guards of the form !isClassicLikeExpansion()
or isClassicLikeExpansion() that prevented ACKs from ever being sent on
Classic/Turtle. Each handler already contained correct legacyGuidAck logic
(full uint64 for Classic/TBC, packed GUID for WotLK) that was unreachable
due to the outer guard.
Classic servers (CMaNGOS/VMaNGOS/ChromieCraft) expect all of these ACKs.
Without them the server stalls the player's speed update, keeps root state
desynced, or generates movement hacks. Fix by removing the erroneous
expansion guard and relying on the existing legacyGuidAck path.
Affected: handleForceSpeedChange, handleForceMoveRootState,
handleForceMoveFlagChange, handleMoveKnockBack, handleTeleport.
dbc_to_csv: The string-column auto-detector would mark integer fields (e.g.
RaceID=1, SexID=0, BaseSection=0-4) as string columns whenever their small
values were valid string-block offsets that happened to land inside longer
strings. Fix by requiring that an offset point to a string *boundary* (offset
0 or immediately after a null byte) rather than any valid position — this
eliminates false positives from integer fields whose values accidentally alias
path substrings. Affected CSVs (CharSections, ItemDisplayInfo for Classic/TBC)
can now be regenerated correctly.
game_handler: clearDBCCache() is already called by application.cpp before
resetDbcCaches(), but also add it inside resetDbcCaches() as a defensive
measure so that future callers of resetDbcCaches() alone also flush stale
expansion-specific DBC data (CharSections, ItemDisplayInfo, etc.).
Classic 1.12 and TBC 2.4.3 don't include questFlags(u32) + isRepeatable(u8)
before each quest title in SMSG_QUESTGIVER_QUEST_LIST. WotLK 3.3.5a added
those 5 bytes. The previous code read them speculatively for all expansions
and only rewound on empty title, which failed for any non-empty title.
Also fix questCount always reading as uint8 (all WoW versions use u8 here).
The old u32/u8 heuristic could misread 4 bytes instead of 1, misaligning all
subsequent quest item reads.
Classic 1.12 auction entries contain only 1 enchant slot (3 uint32s),
while TBC and WotLK expanded this to 3 enchant slots (9 uint32s). Parsing
Classic auction results with the WotLK parser consumed 24 extra bytes per
entry (two extra enchant slots), corrupting randomPropertyId, stackCount,
ownerGuid, pricing and expiry data for every auction item.
- AuctionListResultParser::parse() gains a numEnchantSlots parameter (default 3)
- Classic path reads 1 enchant slot; TBC/WotLK read 3
- handleAuctionListResult/OwnerList/BidderList pass isClassicLikeExpansion()?1:3
Classic 1.12 trainer list entries lack the profDialog and profButton
uint32 fields (8 bytes) that TBC/WotLK added before reqLevel. Instead,
reqLevel immediately follows spellCost, and a trailing unk uint32 appears
at the end of each entry. Parsing the WotLK format for Classic caused
misalignment from the third field onward, corrupting state, cost, level,
skill, and chain data for all trainer spells.
- TrainerListParser::parse() gains a isClassic bool parameter (default false)
- Classic path: cost(4) → reqLevel(1) → reqSkill... → chainNode3 → unk(4)
- WotLK/TBC path: cost(4) → profDialog(4) → profButton(4) → reqLevel(1) → reqSkill...
- handleTrainerList() passes isClassicLikeExpansion() as the flag
Classic 1.12 and TBC use SMSG_FRIEND_LIST (not SMSG_CONTACT_LIST) to send
the initial friend list at login. Previously this packet was silently dropped,
leaving friendsCache empty and breaking /friend remove and note operations
for Classic players.
- Add handleFriendList(): parses Classic format (u8 count, then per-entry:
u64 guid + u8 status + optional area/level/class if online)
- Add handleContactList(): fully parses WotLK SMSG_CONTACT_LIST entries
(previously only read mask+count header and dropped all entries)
- Both handlers populate friendGuids_ and call queryPlayerName() for unknown
GUIDs; handleNameQueryResponse() now backfills friendsCache when a name
resolves for a known friend GUID
- Clear friendGuids_ on disconnect alongside playerNameCache
Vanilla 1.12 SMSG_WHO per-player format:
name(CString) + guild(CString) + level(u32) + class(u32) + race(u32) + zone(u32)
WotLK 3.3.5a added a gender(u8) byte between race and zone. The previous
handleWho always read the gender byte, causing a one-byte misalignment for
Classic/TBC: the first byte of zoneId was consumed as gender, then zoneId
read from the next 4 bytes (spanning into the next player entry).
Now only reads the gender byte for WotLK (isActiveExpansion("wotlk")), and
adds bounds checks to prevent out-of-bounds reads on truncated packets.
Classic 1.12 and TBC 2.4.3 send SMSG_TEXT_EMOTE with the field order:
textEmoteId(u32) + emoteNum(u32) + senderGuid(u64) + nameLen(u32) + name
WotLK 3.3.5a swapped senderGuid to the front:
senderGuid(u64) + textEmoteId(u32) + emoteNum(u32) + nameLen(u32) + name
The previous TextEmoteParser always used the WotLK order, causing senderGuid
to be read as a mashup of textEmoteId+emoteNum for Classic/TBC. Emote
animations and chat entries were associated with wrong GUIDs.
TextEmoteParser::parse now takes a legacyFormat parameter; handleTextEmote
passes it based on expansion detection.
WotLK 3.3.5a added a group-level and per-member roles byte (tank/healer/dps)
for the Dungeon Finder system. Classic 1.12 and TBC 2.4.3 do not send this byte.
The previous GroupListParser always read the roles byte, causing a one-byte
misalignment in Classic/TBC group lists that corrupted member GUID reads and
all subsequent fields (loot method, leader GUID, etc.).
GroupListParser::parse now takes a hasRoles parameter (default true for
backward compatibility). handleGroupList passes hasRoles=isActiveExpansion("wotlk").
Also adds range-checking throughout to prevent out-of-bounds reads on
malformed or unexpectedly short group list packets.
Classic/Vanilla uses ObjectGuid::WriteAsPacked() for party member stats
packets (same packed format as WotLK), not full uint64 as TBC does.
Reading 8 fixed bytes for the GUID over-read the packed GUID field,
misaligning updateFlags and all subsequent stat fields, breaking party
frame HP/mana display in Classic.
Classic 1.12 sends packed GUIDs (byte mask + non-zero bytes) for these
server packets, not full uint64 as TBC does. The previous fixes incorrectly
grouped Classic with TBC, causing the GUID readers to over-read 8 bytes
from what were 2-4 byte packed GUIDs, corrupting health values and spell
IDs parsed from subsequent bytes.
Verified from vmangos/cmangos-classic source code:
SMSG_HEALTH_UPDATE: data << GetPackGUID()
SMSG_POWER_UPDATE: data << GetPackGUID()
SMSG_UPDATE_COMBO_POINTS: data << combotarget->GetPackGUID()
SMSG_PERIODICAURALOG: data << victim->GetPackGUID() + caster->GetPackGUID()
SMSG_SPELLENERGIZELOG: data << victim->GetPackGUID() + caster->GetPackGUID()
TBC continues to use full uint64 for these packets. WotLK and Classic
both use packed GUIDs. The branching now correctly distinguishes TBC
from the rest.
Previously SMSG_SPELL_DELAYED only adjusted the local player's cast bar.
Now it also extends unitCastStates_ for any non-player caster (e.g.
boss cast bar extends correctly when hit by a tank during cast).
- Handle MSG_CHANNEL_START: populate unitCastStates_ for both the local
player and any non-player caster (boss/mob channeled spells); use
full uint64 GUIDs for TBC/Classic, packed GUIDs for WotLK
- Handle MSG_CHANNEL_UPDATE: sync remaining channel time; clear cast
state on channel completion (remainingMs == 0)
- Fix SMSG_RESUME_CAST_BAR: also resumes non-player units' cast bars
(previously only resumed the player's own bar after zone transitions)
- Add party member cast bars in renderPartyFrames: golden progress bar
appears beneath the power bar when a party member is casting,
leveraging the existing unitCastStates_ per-GUID map
WotLK uses packed GUIDs in SMSG_SPELL_FAILURE / SMSG_SPELL_FAILED_OTHER.
TBC 2.4.3 and Classic 1.12 use full uint64 GUIDs. The previous fix used
UpdateObjectParser::readPackedGuid for all expansions, which would
mis-parse the caster GUID on TBC/Classic servers, leaving stale cast
bars and potentially corrupting subsequent packet reads.
Now checks isClassicLikeExpansion() || isActiveExpansion("tbc") and
reads a raw uint64 for those expansions, matching the TBC/Classic wire
format used in parseSpellStart/parseSpellGo overrides.
When a spell fails or is interrupted, the server sends SMSG_SPELL_FAILURE
(for the caster's own POV) or SMSG_SPELL_FAILED_OTHER (for observers).
Previously these were consumed without updating cast state, leaving stale
cast bars for interrupted enemies. Now:
- SMSG_SPELL_FAILURE: erases unitCastStates_[failGuid] for non-player
casters (still clears player casting/currentCastSpellId for own casts)
- SMSG_SPELL_FAILED_OTHER: erases unitCastStates_[guid] for the caster
so boss/enemy cast bars immediately clear on interrupt/kick
Previously the target cast bar tracked a single target using 4 private
fields. This replaces that with unitCastStates_ (unordered_map<uint64_t,
UnitCastState>), tracking cast state for every non-player unit whose
SMSG_SPELL_START we receive.
Changes:
- GameHandler::UnitCastState struct: casting, spellId, timeRemaining,
timeTotal
- getUnitCastState(guid) → returns cast state for any tracked unit
- isTargetCasting(), getTargetCastSpellId(), getTargetCastProgress(),
getTargetCastTimeRemaining() now delegate to getUnitCastState(targetGuid)
- handleSpellStart: tracks all non-player casters (not just the target)
- handleSpellGo: erases caster from map when spell lands
- update loop: ticks down all unit cast states, erasing expired entries
- unitCastStates_ cleared on world reset
- renderBossFrames: shows red cast progress bar per boss slot with
spell name + remaining seconds — critical for instance interrupt play
SMSG_SPELL_START fires for all units, not just the player. Previously only
the player's own cast was tracked; now we also track when the current
target is casting, enabling interrupt decisions.
- GameHandler: track targetCasting_/targetCastSpellId_/targetCastTimeTotal_
/targetCastTimeRemaining_ — updated by SMSG_SPELL_START for the current
target and ticked down in the update loop each frame
- Target cast cleared when: target changes (setTarget), target's spell
lands (SMSG_SPELL_GO), or cast timer expires naturally
- game_screen: renderTargetFrame shows a red cast progress bar between
the power bar and distance line when the target is casting, with
spell name + remaining seconds
- Public accessors: isTargetCasting(), getTargetCastSpellId(),
getTargetCastProgress(), getTargetCastTimeRemaining()
Both SpellGoParser::parse (WotLK) and TbcPacketParsers::parseSpellGo
(TBC) read missCount but did not consume the per-miss (guid + missType)
entries that follow, leaving unread bytes in the packet and silently
corrupting any subsequent parsing of cast-flags–gated spell data.
- Add SpellGoMissEntry{targetGuid, missType} and missTargets vector
to SpellGoData
- WotLK parser now reads packed GUIDs + missType per miss entry
- TBC parser now reads full uint64 GUIDs + missType per miss entry
(9 bytes per entry, bounds-checked)
- handleSpellGo now shows MISS/DODGE/PARRY/BLOCK combat text
for each missed target when the local player cast the spell,
complementing the existing SMSG_SPELLLOGMISS path
- Remove unused foliageLikeModel variable in m2_renderer pass-2 loop
(fix unused-variable warning)
- Update smoke model comment in m2_renderer to reflect current state
SMSG_PET_SPELLS: Parse full packet — pet GUID, react/command state,
10 action bar slots, per-spell entries with autocast flags. Previously
only read the GUID.
SMSG_PET_MODE: Parse petGuid + mode uint32 (command low byte, react
high byte) to keep stance state in sync after server updates.
SMSG_PET_BROKEN: Clear pet state and show "Your pet has died." chat
message.
SMSG_PET_LEARNED_SPELL / SMSG_PET_UNLEARNED_SPELL: Maintain pet spell
list incrementally.
SMSG_PET_CAST_FAILED: Parse and log cast count + spell + reason.
New state accessors: getPetActionSlot(), getPetCommand(), getPetReact(),
getPetSpells(), isPetSpellAutocast().
CMSG_PET_ACTION: Add targetGuid (uint64) field — the wire format
requires petGuid(8)+action(4)+targetGuid(8). Was sending an 12-byte
packet instead of the required 20 bytes.
sendPetAction(): New method that builds and sends CMSG_PET_ACTION with
the correct target guid.
switchTalentSpec() was only updating local state without notifying the
server, leaving the server out of sync with the client's active talent
group. Now sends CMSG_SET_ACTIVE_TALENT_GROUP_OBSOLETE (WotLK wire
opcode 0x4C3) with the target group index (0=primary, 1=secondary),
prompting the server to apply the spec swap and respond with a fresh
SMSG_TALENTS_INFO for the newly active group.
Also adds ActivateTalentGroupPacket::build() to world_packets for the
packet construction.
The SMSG_LFG_PLAYER_REWARD handler was printing raw copper value with
a "g" suffix (e.g. "12345g") instead of converting to gold/silver/copper.
Now formats as "1g 23s 45c" matching the standard WoW convention.
TBC 2.4.3 and Classic 1.12 send resetTime as uint32 (seconds) with no
extended byte, while WotLK 3.3.5a sends uint64 timestamp + extended byte.
Parse the correct field widths based on expansion to prevent corrupted
instance lockout data on TBC/Classic realms.
When a player releases spirit, the server sends SMSG_DEATH_RELEASE_LOC
with the corpse map and position. Store this so the ghost can reclaim.
New flow:
- SMSG_DEATH_RELEASE_LOC now stores corpseMapId_/corpseX_/Y_/Z_ instead
of logging and discarding
- canReclaimCorpse(): true when ghost is on same map within 40 yards of
stored corpse position
- reclaimCorpse(): sends CMSG_RECLAIM_CORPSE (no payload)
- renderReclaimCorpseButton(): shows "Resurrect from Corpse" button at
bottom-center when canReclaimCorpse() is true
Two bugs fixed:
1. acceptResurrect() was always sending CMSG_SPIRIT_HEALER_ACTIVATE even
for player-cast resurrections (Priest/Paladin/Druid). That opcode is
only the correct response to SMSG_SPIRIT_HEALER_CONFIRM. For
SMSG_RESURRECT_REQUEST the server expects CMSG_RESURRECT_RESPONSE
with accept=1. Added resurrectIsSpiritHealer_ to track which path
triggered the dialog and send the right packet per type.
2. The resurrect dialog showed a generic "Return to life?" string
regardless of who cast the resurrection. Parse the optional CString
name from SMSG_RESURRECT_REQUEST (or fall back to playerNameCache)
and display "X wishes to resurrect you." when the caster is known.
TBC 2.4.3 does not have SMSG_AURA_UPDATE (added in WotLK). Instead it
uses SMSG_INIT_EXTRA_AURA_INFO_OBSOLETE (0x3A3) for full aura refresh
on login/zone and SMSG_SET_EXTRA_AURA_INFO_OBSOLETE (0x3A4) for single-
slot updates. Implement handlers for both packets so TBC buff/debuff bars
populate correctly.
Also implement SMSG_CLEAR_EXTRA_AURA_INFO (0x3A6) to remove individual
aura slots when buffs expire or are cancelled server-side.
Format parsed: uint64 targetGuid + uint8 count + per-slot {uint8 slot,
uint32 spellId, uint8 effectIndex, uint8 flags, uint32 durationMs,
uint32 maxDurationMs}. Infinite auras (0xFFFFFFFF) stored as durationMs=-1.
