Chest-type game objects (quest pickups, treasure chests) now send
CMSG_LOOT directly with the GO GUID instead of CMSG_GAMEOBJ_USE +
delayed CMSG_LOOT. The server's loot handler activates the GO and
sends SMSG_LOOT_RESPONSE in one step. The old approach failed because
CMSG_GAMEOBJ_USE opened+despawned the GO before CMSG_LOOT arrived.
Double M2 bone and material descriptor pool sizes (8192 → 16384) to
handle the increased NPC count from the spline parsing fix — patrolling
NPCs that were previously invisible now spawn correctly, exhausting
the old pool limits.
AzerothCore handles loot automatically in the CMSG_GAMEOBJ_USE handler
(calls SendLoot internally). Sending a redundant CMSG_LOOT 200ms later
triggers DoLootRelease() on the server, which closes the loot the server
just opened — before SMSG_LOOT_RESPONSE ever reaches the client. This
broke quest GO interactions (Bundle of Wood, etc.) because the loot
window never appeared and quest items were never granted.
Also remove temporary diagnostic logging from GO interaction path.
Spell descriptions now substitute \$d with actual duration values:
Before: "X damage over X sec"
After: "30 damage over 18 sec"
Implementation:
- DurationIndex field (40) added to all expansion Spell.dbc layouts
- SpellDuration.dbc loaded during cache build: maps index → base ms
- cleanSpellDescription substitutes \$d with resolved seconds/minutes
- getSpellDuration() accessor on GameHandler
Combined with \$s1/\$s2/\$s3 from the previous commit, most common
spell description templates are now fully resolved with real values.
Spell descriptions now substitute \$s1/\$s2/\$s3 template variables
with actual effect base points from Spell.dbc (field 80/81/82).
For example: "causes \$s1 Fire Damage" → "causes 562 Fire Damage".
Implementation:
- Added EffectBasePoints0/1/2 to all 4 expansion DBC layouts
- SpellNameEntry now stores effectBasePoints[3]
- loadSpellNameCache reads base points during DBC iteration
- cleanSpellDescription substitutes \$s1→abs(base)+1 when available
- getSpellEffectBasePoints() accessor on GameHandler
Values are DBC base points (before spell power scaling). Still uses
"X" placeholder for unresolved variables (\$d, \$o1, etc.).
Fire WEATHER_CHANGED(weatherType, intensity) when the server sends
SMSG_WEATHER with a new weather state. Enables weather-aware addons
to react to rain/snow/storm transitions.
GetWeatherInfo() returns current weatherType (0=clear, 1=rain, 2=snow,
3=storm) and intensity (0.0-1.0). Weather data is already tracked by
game_handler and used by the renderer for particle effects and fog.
Add UNIT_FIELD_BYTES_1 to all expansion update field tables (Classic=133,
TBC/WotLK=137). Byte 3 of this field contains the shapeshift form ID
(Bear=1, Cat=3, Travel=4, Moonkin=31, Tree=36, Battle Stance=17, etc.).
Track form changes in the VALUES update handler and fire
UPDATE_SHAPESHIFT_FORM + UPDATE_SHAPESHIFT_FORMS events when the
form changes. This enables stance bar addons and druid form tracking.
New Lua functions:
- GetShapeshiftForm() — returns current form ID (0 = no form)
- GetNumShapeshiftForms() — returns form count by class (Warrior=3,
Druid=6, DK=3, Rogue=1, Priest=1, Paladin=3)
GetEnchantInfo(enchantId) looks up the enchantment name from
SpellItemEnchantment.dbc (field 14). Returns the display name
like "Crusader", "+22 Intellect", or "Mongoose" for a given
enchant ID.
Used by equipment comparison addons and tooltip addons to display
enchantment names on equipped gear. The enchant ID comes from the
item's ITEM_FIELD_ENCHANTMENT update field.
Also adds getEnchantName() to GameHandler for C++ access.
CURRENT_SPELL_CAST_CHANGED fires when the player starts a new cast
via handleSpellStart. Some addons register for this as a catch-all
signal that the current spell state changed, complementing the more
specific UNIT_SPELLCAST_START/STOP/FAILED events.
PLAYER_COMBO_POINTS now fires from the existing SMSG_UPDATE_COMBO_POINTS
handler — the handler already updated comboPoints_ but never notified
Lua addons. Rogue/druid combo point displays and DPS rotation addons
register for this event.
LOOT_READY fires alongside LOOT_OPENED when a loot window opens. Some
addons register for this WoW 5.x+ event name instead of LOOT_OPENED.
The tab-based addon message detection was too aggressive — any chat
message containing a tab character was treated as an addon message
and silently dropped from regular chat display. This could suppress
legitimate player messages containing tabs (from copy-paste).
Now only matches as addon message when:
- Chat type is PARTY/RAID/GUILD/WHISPER/etc. (not SAY/YELL/EMOTE)
- Prefix before tab is <=16 chars (WoW addon prefix limit)
- Prefix contains no spaces (addon prefixes are identifiers)
This prevents false positives while still correctly detecting addon
messages formatted as "DBM4\ttimer:start:10".
UNIT_QUEST_LOG_CHANGED("player") now fires at all 6 locations where
QUEST_LOG_UPDATE fires — quest accept, complete, objective update,
abandon, and server-driven quest log changes. Some addons register
for this event instead of QUEST_LOG_UPDATE (4 registrations in
FrameXML). Both events are semantically equivalent for the player.
Detect addon messages in the SMSG_MESSAGECHAT handler by looking for
the 'prefix\ttext' format (tab delimiter). When detected, fire
CHAT_MSG_ADDON with args (prefix, message, channel, sender) instead
of the regular CHAT_MSG_* event, and suppress the raw message from
appearing in chat.
This enables inter-addon communication used by:
- Boss mods (DBM, BigWigs) for timer/alert synchronization
- Raid tools (oRA3) for ready checks and cooldown tracking
- Group coordination addons for pull countdowns and assignments
Works with the existing SendAddonMessage/RegisterAddonMessagePrefix
functions that format outgoing messages as 'prefix\ttext'.
Some addons register for SPELL_UPDATE_USABLE instead of
ACTIONBAR_UPDATE_USABLE to detect when spell usability changes
due to power fluctuations. Fire both events together when the
player's mana/rage/energy changes.
When the player's mana/rage/energy changes, action bar addons need
ACTIONBAR_UPDATE_USABLE to update button dimming (grey out abilities
the player can't afford). Now fires from both the SMSG_POWER_UPDATE
handler and the SMSG_UPDATE_OBJECT VALUES power field change path.
Without this event, action bar buttons showed as usable even when the
player ran out of mana — the usability state only refreshed on spell
cast attempts, not on power changes.
When a unit's power type changes (e.g., druid shifting from mana to
rage in bear form, or warrior switching stances), fire UNIT_DISPLAYPOWER
so unit frame addons can switch the power bar display (mana blue bar →
rage red bar). Detected via UNIT_FIELD_BYTES_0 byte 3 changes in the
VALUES update path.
RAID_ROSTER_UPDATE now fires alongside GROUP_ROSTER_UPDATE when the
group type is raid, matching the event that raid frame addons register
for (6 registrations in FrameXML). Fires from group list updates and
group uninvite handlers.
UNIT_LEVEL fires when any tracked unit (player, target, focus, pet)
changes level via VALUES update fields. Used by unit frame addons to
update level display (5 registrations in FrameXML).
setActionBarSlot (called from PickupAction/PlaceAction drag-drop and
from server-driven action button updates) updated the slot data and
notified the server, but never fired the Lua addon event. Action bar
addons (Bartender4, Dominos) register for ACTIONBAR_SLOT_CHANGED to
refresh button textures, tooltips, and cooldown state when slots change.
Also fires ACTIONBAR_UPDATE_STATE for general action bar refresh.
PLAYER_DEAD only fired from SMSG_FORCED_DEATH_UPDATE (GM kill) — the
normal death path (health dropping to 0 via VALUES update) never fired
it. Death-related addons and the default release spirit dialog depend
on this event.
Also add PLAYER_ALIVE (fires when resurrected without having been a
ghost) and PLAYER_UNGHOST (fires when player rezzes from ghost form)
at the health-restored-from-zero VALUES path. These events control
the transition from ghost form back to alive, letting addons restore
normal UI state after death.
handleTextEmote pushed emote messages directly to chatHistory
instead of using addLocalChatMessage, so Lua chat addons never
received CHAT_MSG_TEXT_EMOTE events for /wave, /dance, /bow, etc.
from other players. Use addLocalChatMessage which fires the event
and also notifies the C++ display callback.
Implement keyboard modifier queries using ImGui IO:
- IsShiftKeyDown, IsControlKeyDown, IsAltKeyDown
- IsModifiedClick(action) — CHATLINK=Shift, DRESSUP=Ctrl, SELFCAST=Alt
- GetModifiedClick/SetModifiedClick for keybind configuration
Fire UPDATE_EXHAUSTION and PLAYER_UPDATE_RESTING events when rest state
changes (entering/leaving inns and cities) and when rested XP updates.
XP bar addons use UPDATE_EXHAUSTION to show the rested bonus indicator.
Fire UI_ERROR_MESSAGE from addUIError() so Lua addons can react to
error messages like "Not enough mana" or "Target is too far away".
Previously only the C++ overlay callback was notified. Also add
addUIInfoMessage() helper for informational system messages.
Fire QUEST_REMOVED and QUEST_LOG_UPDATE when quests are removed from
the quest log — both via server-driven removal (SMSG_QUEST_UPDATE_FAILED
etc.) and player-initiated abandon (CMSG_QUESTLOG_REMOVE_QUEST). Quest
tracking addons like Questie register for these events to update their
map markers and objective displays.
Classic and Turtle WoW don't use SMSG_AURA_UPDATE packets — they
pack aura data into UNIT_FIELD_AURAS update fields. The code correctly
rebuilds playerAuras from these fields in both CREATE_OBJECT and VALUES
update paths, but never fired the UNIT_AURA("player") addon event.
Buff frame addons (Buffalo, ElkBuffBars, etc.) register for UNIT_AURA
to refresh their display. Without this event, buff frames on Classic
and Turtle never update when buffs are gained or lost.
addLocalChatMessage only pushed to chatHistory and called the C++
display callback — it never fired Lua addon events. This meant the
player's own sent messages (local echoes from sendChatMessage) and
system messages (loot, XP gains, errors) were invisible to Lua chat
frame addons.
Now fires CHAT_MSG_{type} with the full 12-arg WoW signature from
addLocalChatMessage, matching the incoming message path. Uses the
active character name as sender for player-originated messages.
The SMSG_MESSAGECHAT handler stored messages in chatHistory and
triggered chat bubbles, but never fired Lua addon events. Chat frame
addons (Prat, Chatter, WIM) and the default ChatFrame all register for
CHAT_MSG_SAY, CHAT_MSG_WHISPER, CHAT_MSG_PARTY, CHAT_MSG_GUILD, etc.
to display incoming messages.
Now fires CHAT_MSG_{type} for every incoming message with the full WoW
event signature: message, senderName, language, channelName, displayName,
specialFlags, zoneChannelID, channelIndex, channelBaseName, unused,
lineID, and senderGUID. Covers all chat types: SAY, YELL, WHISPER,
PARTY, RAID, GUILD, OFFICER, CHANNEL, EMOTE, SYSTEM, MONSTER_SAY, etc.
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.
