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.
Returns "TANK", "HEALER", "DAMAGER", or "NONE" based on the WotLK LFG
roles bitmask from SMSG_GROUP_LIST. Used by raid frame addons (Grid,
VuhDo, Healbot) to display role icons next to player names.
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.
UnitCanAttack(unit, otherUnit): returns true if otherUnit is hostile
(attackable). UnitCanCooperate(unit, otherUnit): returns true if
otherUnit is friendly (can receive beneficial spells).
Used by nameplate addons for coloring and by targeting addons for
filtering hostile/friendly units.
Returns the creature family name (Wolf, Cat, Bear, etc.) for NPC units.
Data from CreatureInfo cache (creature_template family field). Used by
hunter pet management addons and tooltips that show pet family info.
Enhance RAID_CLASS_COLORS entries with colorStr hex string field and
GenerateHexColor()/GenerateHexColorMarkup() methods. Many addons
(Prat, Details, oUF) use colorStr to build colored chat text and
GenerateHexColor for inline color markup.
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.
Returns a table of power cost entries: {{ type=powerType, cost=amount,
name=powerName }}. Data from SpellDataResolver (Spell.dbc ManaCost and
PowerType fields). Used by spell tooltip addons and action bar addons
that display mana/rage/energy costs.
Returns true when the player is on a taxi/flight path. Used by action
bar addons to disable abilities during flight and by map addons to
track taxi state.
Previously UnitIsDead returned false for out-of-range party members
(entity not in entity manager). Now checks curHealth==0 from
SMSG_PARTY_MEMBER_STATS data, so raid frame addons correctly show
dead members in other zones as dead.
Previously UnitPowerType returned 0 (MANA) for party members who are
out of entity range. Now falls back to SMSG_PARTY_MEMBER_STATS power
type data, so raid frame addons correctly color rage/energy/runic
power bars for distant party members.
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.
Implement UnitDetailedThreatSituation(unit, mobUnit) returning:
- isTanking (boolean)
- status (0-3, same as UnitThreatSituation)
- threatPct (100 if tanking, 0 otherwise)
- rawThreatPct (same)
- threatValue (0 — no server threat data available)
Used by Omen and other threat meter addons that query detailed threat
info per mob-target pair.
Implement UnitThreatSituation(unit, mobUnit) returning 0-3 threat level:
- 0: not on threat table
- 1: in combat but not tanking (mob targeting someone else)
- 3: securely tanking (mob is targeting this unit)
Approximated from mob's UNIT_FIELD_TARGET to determine who the mob is
attacking. Used by threat meter addons (Omen, ThreatPlates) and tank
UI addons to display threat state.
Add three tapped-state query functions for addons:
- UnitIsTapped(unit): true if any player has tagged the mob
- UnitIsTappedByPlayer(unit): true if local player can loot (tapped+lootable)
- UnitIsTappedByAllThreatList(unit): true if shared-tag mob
Used by nameplate addons (Plater, TidyPlates) and unit frame addons
to determine and display tap ownership state.
Extend tapped-by-other detection to the focus frame, matching the
target frame and nameplate treatment. All three UI elements (nameplate,
target frame, focus frame) now consistently show grey for tapped mobs.
Extend the tapped-by-other-player check to the target frame. Mobs
tagged by another player now show a grey name color on the target
frame, matching the grey nameplate treatment and WoW's behavior.
Players can now see at a glance on both nameplates AND target frame
whether a mob is tagged.
Check UNIT_DYNFLAG_TAPPED_BY_PLAYER (0x0004) on hostile NPC nameplates.
Mobs tagged by another player now show grey health bars instead of red,
matching WoW's visual indication that the mob won't yield loot/XP.
Mobs with TAPPED_BY_ALL_THREAT_LIST (0x0008) still show red since
those are shared-tag mobs that give loot to everyone.
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".
Extend the Lua error UI display to cover all error paths:
- OnUpdate frame callbacks (previously only logged)
- executeFile loading errors (now also shown as UI error)
- executeString /run errors (now also shown as UI error)
This ensures addon developers see ALL Lua errors in-game, not just
event handler errors from the previous commit.
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.
Previously Lua addon errors only logged to the log file. Now they
display as red UI error text to the player (same as spell errors and
game warnings), helping addon developers debug issues in real-time.
Add LuaErrorCallback to LuaEngine, fire it from event handler and
frame OnEvent pcall error paths. Wire the callback to GameHandler's
addUIError in application.cpp.
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.
