In the CREATE update block, the ufNpcFlags check at the end of the
else-if chain was unreachable dead code — it was already handled
earlier in the same chain. Remove the duplicate.
In the VALUES update block, mount display changes via field updates
fired mountCallback_ but not the UNIT_MODEL_CHANGED addon event,
unlike the CREATE path which fired both. Add the missing event so
Lua addons are notified when the player mounts/dismounts via VALUES
updates (the common case for aura-based mounting).
Also fire UNIT_MODEL_CHANGED for target/focus/pet display ID changes
in the VALUES displayIdChanged path, matching the CREATE path behavior.
PLAYER_ENTERING_WORLD is the single most important WoW addon event —
virtually every addon registers for it to initialize UI, state, and
data structures. It was never fired, causing widespread addon init
failures on login and after teleports.
Now fired from:
- handleLoginVerifyWorld (initial login + same-map teleports)
- handleNewWorld (cross-map teleports, instance transitions)
Also fires:
- PLAYER_LOGIN on initial world entry only
- ZONE_CHANGED_NEW_AREA on all world entries
- UPDATE_WORLD_STATES on initial entry
- SPELLS_CHANGED + LEARNED_SPELL_IN_TAB after SMSG_INITIAL_SPELLS
(so spell book addons can initialize on login)
Implement GetNumSpellTabs, GetSpellTabInfo, GetSpellBookItemInfo, and
GetSpellBookItemName — the core functions SpellBookFrame.lua needs to
organize known spells into class skill line tabs.
Tabs are built lazily from knownSpells grouped by SkillLineAbility.dbc
mappings (category 7 = class). A "General" tab collects spells not in
any class skill line. Tabs auto-rebuild when the spell count changes.
Also adds SpellBookTab struct and getSpellBookTabs() to GameHandler.
Expose cast/channel state to Lua addons via UnitCastingInfo(unit) and
UnitChannelInfo(unit), matching the WoW API signature (name, text, texture,
startTime, endTime, isTradeSkill, castID, notInterruptible). Works for
player, target, focus, and pet units using existing UnitCastState tracking.
Also fix handleCastFailed (SMSG_CAST_FAILED, Classic/TBC path) to fire
UNIT_SPELLCAST_FAILED and UNIT_SPELLCAST_STOP events — previously only
the WotLK SMSG_CAST_RESULT path fired these, leaving Classic/TBC addons
unaware of cast failures.
Adds isChannel field to UnitCastState and getCastTimeTotal() accessor.
When logging in while already dead (reconnect/crash recovery), send
MSG_CORPSE_QUERY to get the server-authoritative corpse location.
Without this, the minimap corpse marker would be missing or point to
the wrong position after reconnecting as a ghost.
Parse MSG_CORPSE_QUERY server response to get the exact corpse location
and map ID. Also send the query after releasing spirit so the minimap
corpse marker points to the correct position even when the player died
in an instance and releases to an outdoor graveyard.
Previously the corpse position was only set from the entity death
location, which could be wrong for cross-map ghost runs.
Fire AUTOFOLLOW_BEGIN when the player starts following another unit
via /follow. Fire AUTOFOLLOW_END when following is cancelled. Used by
movement addons and AFK detection addons.
Fire PLAYER_LOGOUT from SMSG_LOGOUT_RESPONSE when the server confirms
logout. Addons use this to save state and perform cleanup before the
player leaves the world.
Fire QUEST_TURNED_IN with questId from SMSG_QUESTGIVER_QUEST_COMPLETE
when a quest is successfully completed and removed from the quest log.
Used by quest tracking addons (Questie, QuestHelper) and achievement
tracking addons.
Fire CHAT_MSG_COMBAT_XP_GAIN from SMSG_EXPLORATION_EXPERIENCE when the
player discovers a new area and gains exploration XP. Used by XP
tracking addons to count all XP sources including discovery.
Fire CHAT_MSG_COMBAT_FACTION_CHANGE with the reputation change message
alongside UPDATE_FACTION when faction standings change. Used by
reputation tracking addons (FactionFriend, RepHelper) that parse
reputation gain messages.
Fire TRAINER_UPDATE from SMSG_TRAINER_BUY_SUCCEEDED so trainer UI
addons refresh the spell list (marking learned spells as unavailable).
Also fire SPELLS_CHANGED so spellbook and action bar addons detect
the newly learned spell.
Fire UNIT_MODEL_CHANGED for the player when mount display ID changes
(mounting or dismounting). Mount addons and portrait addons now get
notified when the player's visual model switches between ground and
mounted form.
Fire UPDATE_WORLD_STATES from SMSG_UPDATE_WORLD_STATE when BG scores,
zone capture progress, or other world state variables change. Used by
BG score addons and world PvP objective tracking addons.
Fire UNIT_THREAT_LIST_UPDATE from SMSG_THREAT_UPDATE,
SMSG_HIGHEST_THREAT_UPDATE, and SMSG_THREAT_CLEAR. Threat data is
already parsed and stored in threatLists_ — this event notifies
addon systems when the data changes.
Used by Omen, ThreatPlates, and other threat meter addons to refresh
their displays when threat values update.
Fire UNIT_FLAGS for player/target/focus when UNIT_FIELD_FLAGS updates.
Covers PvP flag, combat state, silenced, disarmed, and other flag
changes. Used by nameplate addons for PvP indicators and by unit frame
addons tracking CC/silence state.
Fire UNIT_FACTION for player/target/focus when UNIT_FIELD_FACTIONTEMPLATE
updates. Covers PvP flag toggling, mind control faction swaps, and any
server-side faction changes. Used by nameplate addons to update hostility
coloring and by PvP addons tracking faction state.
Fire UNIT_MODEL_CHANGED for player/target/focus/pet when their
UNIT_FIELD_DISPLAYID update field changes. This covers polymorph,
mount display changes, shapeshifting, and model swaps.
Used by unit frame addons that display 3D portraits and by nameplate
addons that track model state changes.
Fire MIRROR_TIMER_PAUSE from SMSG_PAUSE_MIRROR_TIMER with paused state
(1=paused, 0=resumed). Completes the mirror timer event trio alongside
MIRROR_TIMER_START and MIRROR_TIMER_STOP.
Fire BARBER_SHOP_OPEN when the barber shop UI is enabled
(SMSG_ENABLE_BARBER_SHOP). Fire BARBER_SHOP_CLOSE when the barber
shop completes or is dismissed. Used by UI customization addons.
Fire MIRROR_TIMER_START with type, value, maxValue, scale, and paused
args when breath/fatigue/fire timers begin. Fire MIRROR_TIMER_STOP with
type when they end. Timer types: 0=fatigue, 1=breath, 2=fire.
Used by timer bar addons to display breath/fatigue countdown overlays.
Fire BAG_UPDATE and UNIT_INVENTORY_CHANGED from SMSG_ITEM_PUSH_RESULT
when any item is received (loot, quest reward, trade, mail). Bag addons
(Bagnon, AdiBags) immediately show new items, and equipment tracking
addons detect inventory changes.
Fire PET_BAR_UPDATE when:
- Pet is summoned (SMSG_PET_SPELLS with new spell list)
- Pet learns a new spell (SMSG_PET_LEARNED_SPELL)
Used by pet action bar addons to refresh their display when the pet's
available abilities change.
Fire GUILD_INVITE_REQUEST when another player invites the local player
to a guild. Includes inviterName and guildName as arguments. Used by
auto-accept guild addons and invitation notification addons.
Fire PARTY_INVITE_REQUEST when another player invites the local player
to a group. Used by auto-accept group addons and invite notification
addons. Includes the inviter's name as the first argument.
Fire CONFIRM_TALENT_WIPE with the gold cost when the trainer offers
to reset talents (MSG_TALENT_WIPE_CONFIRM). Used by talent management
addons to show the respec cost dialog.
SMSG_GROUP_DESTROYED clears all party state but wasn't firing addon
events. Raid frame addons (Grid, VuhDo, Healbot) now properly hide
when the group disbands. Also fires PARTY_MEMBERS_CHANGED for compat.
SMSG_SELL_ITEM success now fires BAG_UPDATE so bag addons refresh
their display, and PLAYER_MONEY so gold tracking addons see the
sell price income immediately.
Fire RESURRECT_REQUEST with the caster's name from SMSG_RESURRECT_REQUEST
when a player/NPC offers to resurrect the dead player. Used by auto-accept
resurrection addons and death tracking addons.
Fire CONFIRM_SUMMON from SMSG_SUMMON_REQUEST when another player
summons via warlock portal or meeting stone. Used by auto-accept
summon addons and summon notification addons.
Track horizontal movement flag transitions (forward/backward/strafe)
and fire events when the player starts or stops moving. Used by
Healbot, cast-while-moving addons, and nameplate addons that track
player movement state for positioning optimization.
The loot money handler directly updates playerMoneyCopper_ but wasn't
firing PLAYER_MONEY. The update object path fires it when the coinage
field changes, but there can be a delay. Now gold-tracking addons
(Accountant, GoldTracker) immediately see looted money.
Fire UNIT_PET with "player" as arg from SMSG_PET_SPELLS when:
- Pet is cleared (dismissed/dies) — both size-based and guid=0 paths
- Pet is summoned (new pet GUID received with spell list)
Used by pet frame addons and unit frame addons to show/hide pet
frames and update pet action bars when pet state changes.
SMSG_HEALTH_UPDATE and SMSG_POWER_UPDATE were not checking for the pet
GUID when dispatching addon events. Pet health/power bar addons now
properly receive UNIT_HEALTH and UNIT_POWER with unitId="pet".
The UPDATE_OBJECT and UNIT_AURA paths already had the pet check.
Add pet GUID check to all spellcast event dispatchers:
- UNIT_SPELLCAST_START
- UNIT_SPELLCAST_SUCCEEDED
- UNIT_SPELLCAST_CHANNEL_START
- UNIT_SPELLCAST_CHANNEL_STOP
- UNIT_SPELLCAST_INTERRUPTED + STOP
Previously these events only fired for player/target/focus, meaning
pet cast bars and pet spell tracking addons wouldn't work. Now pet
spellcasts properly fire with unitId="pet".
Fire UPDATE_BATTLEFIELD_STATUS with the status code when battlefield
status changes (queued, ready to join, in progress, waiting to leave).
Used by BG queue addons and PvP addons to track battleground state.
Fire CHAT_MSG_COMBAT_HONOR_GAIN from SMSG_PVP_CREDIT with the honor
message text. Used by PvP addons (HonorSpy, HonorTracker) to track
honor gains and kill counts.
Fire PLAYER_CONTROL_LOST when SMSG_CLIENT_CONTROL_UPDATE revokes player
movement (stun, fear, mind control, etc.) and PLAYER_CONTROL_GAINED when
movement is restored.
Used by loss-of-control addons and action bar addons to show stun/CC
indicators and disable ability buttons during crowd control.
Fire MAIL_INBOX_UPDATE when the mail list is received/refreshed
(SMSG_MAIL_LIST_RESULT), so mail addons can update their display.
Fire UPDATE_PENDING_MAIL when new mail arrives (SMSG_RECEIVED_MAIL),
enabling minimap mail icon addons and notification addons to react.
Fire QUEST_WATCH_UPDATE (with quest ID for kills) and QUEST_LOG_UPDATE
when quest objectives progress:
- Kill objectives: when SMSG_QUESTUPDATE_ADD_KILL updates a kill count
- Item objectives: when SMSG_QUESTUPDATE_ADD_ITEM updates an item count
Used by quest tracker addons (Questie, QuestHelper) and the built-in
quest tracker to refresh objective display when progress changes.
Fire MERCHANT_UPDATE after a successful SMSG_BUY_ITEM so vendor addons
refresh their stock display. Also fire BAG_UPDATE so bag addons show
the newly purchased item immediately.
SMSG_SPELL_FAILED_OTHER was clearing the unit cast state but not firing
addon events. Cast bar addons (Quartz, ClassicCastbars) showing target/
focus cast bars need UNIT_SPELLCAST_FAILED and UNIT_SPELLCAST_STOP to
clear the bar when another unit's cast fails.
Now fires both events for target and focus units, matching the behavior
already implemented for the player's own cast failures.
Fire PLAYER_GUILD_UPDATE when the player's guild membership changes:
- When guild name is first resolved (player joins guild/logs in)
- When guild is disbanded
Used by guild frame addons and guild info display to update when
guild status changes.
Fire PARTY_LEADER_CHANGED (with GROUP_ROSTER_UPDATE) from both:
- SMSG_GROUP_SET_LEADER: when a new leader is named by string
- SMSG_REAL_GROUP_UPDATE: when leader GUID changes via group update
Used by raid frame addons to update leader crown icons and by
group management addons to track leadership changes.
Fire INSPECT_READY with the inspected player's GUID when inspection
results are received. Fires from both:
- WotLK SMSG_TALENTS_INFO type=1 (talent + gear inspect)
- Classic SMSG_INSPECT (gear-only inspect)
Used by GearScore, TacoTip, and other inspection addons that need
to know when inspect data is available for a specific player.
Fire RAID_TARGET_UPDATE event when raid markers (skull, cross, etc.)
are set or cleared on targets. Add two Lua API functions:
- GetRaidTargetIndex(unit) returns marker index 1-8 (or nil)
- SetRaidTarget(unit, index) sets marker 1-8 (or 0 to clear)
Enables raid marking addons and nameplate addons that display raid
icons to react to marker changes in real-time.
Fire addon events for the raid ready check system:
- READY_CHECK fires when a ready check is initiated, with initiator name
- READY_CHECK_CONFIRM fires for each player's response, with GUID and
ready state (1=ready, 0=not ready)
- READY_CHECK_FINISHED fires when the ready check period ends
These events are used by raid frame addons (Grid, VuhDo, Healbot) to
show ready check status on unit frames, and by raid management addons
to track responsiveness.
Fire ACHIEVEMENT_EARNED event when a player earns an achievement,
enabling achievement tracking addons.
Add 15 previously unmapped chat type → addon event mappings:
- CHAT_MSG_ACHIEVEMENT, CHAT_MSG_GUILD_ACHIEVEMENT
- CHAT_MSG_WHISPER_INFORM (echo of sent whispers)
- CHAT_MSG_RAID_LEADER, CHAT_MSG_BATTLEGROUND_LEADER
- CHAT_MSG_MONSTER_SAY/YELL/EMOTE/WHISPER
- CHAT_MSG_RAID_BOSS_EMOTE/WHISPER
- CHAT_MSG_BG_SYSTEM_NEUTRAL/ALLIANCE/HORDE
These events are needed by boss mod addons (DBM, BigWigs) to detect
boss emotes, by achievement trackers, and by chat filter addons that
process all message types.
Add playerClassRaceCache_ that stores classId and raceId from
SMSG_NAME_QUERY_RESPONSE. This enables UnitClass and UnitRace to return
correct data for players who were previously seen but are now out of
UPDATE_OBJECT range.
Fallback chain for UnitClass/UnitRace is now:
1. Entity update fields (UNIT_FIELD_BYTES_0) — for nearby entities
2. Name query cache — for previously queried players
3. getPlayerClass/Race() — for the local player
This improves class-colored names in chat, unit frames, and nameplates
for players who move out of view range.
Fix bug where NPCs receiving moveType=4 (FacingAngle) or moveType=3
(FacingTarget) monster move packets with zero waypoints would not
rotate in place. The handler only processed orientation when hasDest
was true, but facing-only updates have no destination waypoints.
Now NPCs properly rotate when:
- moveType=4: server specifies an exact facing angle (e.g., NPC turns
to face the player during dialogue or scripted events)
- moveType=3: NPC should face a specific target entity
This fixes NPCs appearing frozen/unresponsive during scripted events,
quest interactions, and patrol waypoint facing changes.
