Add the UIDropDownMenu compatibility framework used by virtually every
addon with settings or selection menus: UIDropDownMenu_Initialize,
CreateInfo, AddButton, SetWidth, SetText, GetText, SetSelectedID, etc.
Add global font object stubs (GameFontNormal, GameFontHighlight, etc.)
referenced by CreateFontString template arguments.
Add UISpecialFrames table, InterfaceOptionsFrame for addon panels,
InterfaceOptions_AddCategory, and common font color constants
(GRAY_FONT_COLOR, NORMAL_FONT_COLOR, etc.).
These globals prevent nil-reference errors in most popular addons.
Fire PLAYER_ENTER_COMBAT when the player's auto-attack starts
(SMSG_ATTACKSTART) and PLAYER_LEAVE_COMBAT when auto-attack stops.
These events are distinct from PLAYER_REGEN_DISABLED/ENABLED — they
specifically track physical melee combat state and are used by
combat-aware addons for weapon swing timers and attack state tracking.
Fix bug where learning a talent caused an early return before firing
LEARNED_SPELL_IN_TAB and SPELLS_CHANGED events, leaving talent addons
unaware of changes. Now talent learning fires CHARACTER_POINTS_CHANGED,
PLAYER_TALENT_UPDATE, LEARNED_SPELL_IN_TAB, and SPELLS_CHANGED.
Also fire CHARACTER_POINTS_CHANGED, ACTIVE_TALENT_GROUP_CHANGED, and
PLAYER_TALENT_UPDATE from handleTalentsInfo (SMSG_TALENTS_INFO), so
talent addons update when the full talent state is received from the
server (login, spec switch, respec).
Also fire UNIT_HEALTH/UNIT_POWER events from SMSG_HEALTH_UPDATE and
SMSG_POWER_UPDATE packets for real-time unit frame updates.
SMSG_HEALTH_UPDATE and SMSG_POWER_UPDATE are high-frequency WotLK
packets that update entity health/power values but weren't firing
addon events. Unit frame addons (Pitbull, oUF, SUF) depend on these
events to update health/mana bars in real-time.
Now fire UNIT_HEALTH for player/target/focus on SMSG_HEALTH_UPDATE
and UNIT_POWER on SMSG_POWER_UPDATE, matching the events already
fired from the UPDATE_OBJECT path.
Implement 5 talent-related WoW Lua API functions:
- GetNumTalentTabs() returns class-specific talent tree count (usually 3)
- GetTalentTabInfo(tab) returns name, icon, pointsSpent, background
- GetNumTalents(tab) returns talent count in a specific tree
- GetTalentInfo(tab, index) returns full 8-value tuple with name, tier,
column, current rank, max rank, and availability
- GetActiveTalentGroup() returns active spec (1 or 2)
Data sourced from Talent.dbc, TalentTab.dbc, and the server-sent talent
info packet. Enables talent addons and spec display addons.
Implement skill line API functions that profession and tradeskill addons
need to display player skills:
- GetNumSkillLines() returns count of player skills
- GetSkillLineInfo(index) returns full 12-value tuple: name, isHeader,
isExpanded, rank, tempPoints, modifier, maxRank, isAbandonable, etc.
Data comes from SMSG_SKILLS_INFO update fields and SkillLine.dbc names.
Implement LibStub — the universal library version management system that
virtually every WoW addon framework depends on (Ace3, LibDataBroker,
LibSharedMedia, etc.). Without LibStub, most popular addons fail to load.
Also implement CallbackHandler-1.0 — the standard event callback library
used by Ace3-based addons for inter-module communication. Supports
RegisterCallback, UnregisterCallback, UnregisterAllCallbacks, and Fire.
These two libraries unlock the entire Ace3 addon ecosystem.
Fire UNIT_SPELLCAST_SENT when the player initiates a spell cast (before
server confirms), enabling cast bar addons like Quartz to show latency.
Includes target name and spell ID as arguments.
Fire UNIT_SPELLCAST_STOP whenever a cast bar should disappear:
- On successful cast completion (SMSG_SPELL_GO)
- On cast failure (SMSG_CAST_RESULT with error)
- On spell interrupt (SMSG_SPELL_FAILURE/SMSG_SPELL_FAILED_OTHER)
- On manual cast cancel
These events are essential for cast bar replacement addons to properly
track when casts begin and end.
Implement 3 critical gameplay Lua API functions:
- UseAction(slot) activates an action bar slot (spell/item), enabling
action bar addons like Bartender/Dominos to fire abilities
- CancelUnitBuff("player", index) cancels a buff by index, enabling
auto-cancel and buff management addons
- CastSpellByID(id) casts a spell by numeric ID, enabling macro addons
and spell queuing systems
Fire UNIT_HEALTH, UNIT_POWER, and UNIT_AURA events from
SMSG_PARTY_MEMBER_STATS with proper unit IDs (party1..4, raid1..40).
Previously, health/power changes for party members via the stats packet
were silent — raid frame addons never got notified.
Also fix closeLoot() not firing LOOT_CLOSED event when the loot window
is closed by the player (only handleLootReleaseResponse fired it).
Fix GetScreenWidth/GetScreenHeight/GetNumLootItems/GetFramerate being
overridden by hardcoded Lua stubs that ran after the C functions were
registered. Now the real C implementations correctly take effect.
Add GameTooltip global frame with 20+ methods (SetOwner, ClearLines,
AddLine, AddDoubleLine, SetText, NumLines, GetText, SetHyperlink, etc.)
and ShoppingTooltip1/2 — critical for virtually all WoW addons.
Add frame:CreateTexture() and frame:CreateFontString() methods returning
stub objects with common API methods, enabling UI creation addons.
Add real GetFramerate() returning actual FPS from ImGui.
Support compound unit IDs that resolve an entity's current target via
UNIT_FIELD_TARGET_LO/HI update fields. This enables addons to query
target-of-target info (e.g., UnitName("targettarget"), UnitHealth("focustarget"))
which is essential for threat meters and unit frame addons.
Fire the following events for addon compatibility:
- LOOT_OPENED, LOOT_CLOSED on loot window open/close
- GOSSIP_SHOW, GOSSIP_CLOSED on gossip/quest-list window open/close
- QUEST_DETAIL when quest details are shown to the player
- QUEST_COMPLETE when quest offer reward dialog opens
- TRAINER_SHOW, TRAINER_CLOSED on trainer window open/close
Implement 10 new WoW Lua API functions for addon compatibility:
- GetComboPoints, UnitReaction, UnitIsConnected for unit frames/raid addons
- HasAction, GetActionTexture, IsCurrentAction, IsUsableAction, GetActionCooldown
for action bar addons (Bartender, Dominos, etc.)
- UnitMana/UnitManaMax as Classic-era aliases for UnitPower/UnitPowerMax
Add "mouseover" as a valid unit ID in resolveUnitGuid so Lua API functions
like UnitName("mouseover"), UnitHealth("mouseover") etc. work for addons.
Fire UPDATE_MOUSEOVER_UNIT event when the mouseover target changes, and
PLAYER_FOCUS_CHANGED event when focus is set or cleared.
Fire MAIL_SHOW when mailbox opens (SMSG_SHOW_MAILBOX) and MAIL_CLOSED
when it closes. Fire AUCTION_HOUSE_SHOW when AH opens and AUCTION_HOUSE_CLOSED
when it closes. Used by mail addons (Postal) and AH addons (Auctionator).
Fire BANKFRAME_OPENED when bank window opens and BANKFRAME_CLOSED when
it closes. Used by bank management addons (Bagnon, BankItems) to detect
when the player is interacting with their bank.
Fire MERCHANT_SHOW when vendor window opens (SMSG_LIST_INVENTORY) and
MERCHANT_CLOSED when vendor is closed. Used by vendor price addons and
auto-sell addons that need to detect vendor interaction state.
Fire when SMSG_ACTION_BUTTONS populates the action bar on login and when
SMSG_SUPERCEDED_SPELL upgrades spell ranks on the bar. Used by action bar
addons (Bartender, Dominos) to refresh their displays.
Detect changes in player skill values after extractSkillFields() and fire
SKILL_LINES_CHANGED when any skill value changes. Used by profession
tracking addons and skill bar displays.
Fire CHAT_MSG_MONEY when gold is looted (used by gold tracking addons
like MoneyFu, Titan Panel). Fire CHAT_MSG_COMBAT_XP_GAIN when XP is
earned (used by XP tracking addons and leveling speed calculators).
Fire CHAT_MSG_LOOT addon event from SMSG_ITEM_PUSH_RESULT with the loot
message text, item ID, and count. Used by loot tracking addons (AutoLootPlus,
Loot Appraiser) and damage meters that track loot distribution.
Fires when AFK/DND status, PvP flag, ghost state, or other player flags
change via PLAYER_FLAGS update field. Enables addons that track player
status changes (FlagRSP, TRP3, etc.).
Parse randomPropertyId from SMSG_AUCTION_OWNER_NOTIFICATION to display
full item names in sold/bid/expired messages like "Your auction of
Gloves of the Monkey has sold!" Completes suffix resolution across
all 9 item display contexts.
Apply getRandomPropertyName() to SMSG_AUCTION_BIDDER_NOTIFICATION and
SMSG_AUCTION_REMOVED_NOTIFICATION so outbid/expired messages show full
item names like "You have been outbid on Leggings of the Eagle" instead
of just "Leggings". Completes suffix name resolution across all AH contexts.
Formats copper amounts into "Xg Ys Zc" strings for addon display.
GetCoinText is aliased to GetCoinTextureString. Used by money display
addons (Titan Panel, MoneyFu) and auction/vendor price formatting.
Returns (class, englishClass, race, englishRace, sex, name, realm) for a
GUID string. Resolves player name from entity cache. Returns class/race
info for the local player. Used by Details!, Recount, and Skada to
identify players in COMBAT_LOG_EVENT_UNFILTERED data.
Returns WoW-format quality-colored item link for any item ID from the
item info cache. Used by loot addons, tooltip addons, and chat formatting
to create clickable item references.
Returns WoW-format spell link string "|cff71d5ff|Hspell:ID|h[Name]|h|r"
for a spell ID or name. Used by damage meters, chat addons, and WeakAuras
to create clickable spell references in chat messages.
Extend random property name resolution to the Bids tab and Your Auctions
(seller) tab. All three auction house tabs now display items with their
full suffix names (e.g., "Gloves of the Monkey" instead of "Gloves").
Append suffix name from getRandomPropertyName() to auction browse results
so items display as "Leggings of the Eagle" instead of just "Leggings"
in the auction house search table. Uses the randomPropertyId field from
the SMSG_AUCTION_LIST_RESULT packet data.
Apply getRandomPropertyName() to SMSG_LOOT_START_ROLL and SMSG_LOOT_ROLL_WON
handlers so items with random suffixes display correctly in group loot
contexts (e.g., "Leggings of the Eagle" in the Need/Greed popup and
"Player wins Leggings of the Eagle (Need 85)" in chat).
Load ItemRandomProperties.dbc and ItemRandomSuffix.dbc lazily to resolve
suffix names like "of the Eagle", "of the Monkey" etc. Add
getRandomPropertyName(id) callback on GameHandler wired through Application.
Append suffix to item names in SMSG_ITEM_PUSH_RESULT loot notifications
so items display as "Leggings of the Eagle" instead of just "Leggings".
Previously returned (0, remaining) which broke addons computing remaining
time as start + duration - GetTime(). Now returns (GetTime(), remaining, 1)
when on cooldown and (0, 0, 1) when off cooldown, plus the third 'enabled'
value that WoW always returns. Fixes cooldown display in OmniCC and similar.
GetXPExhaustion() returns rested XP pool remaining (nil if none).
GetRestState() returns 1 (normal) or 2 (rested) based on inn/city state.
Used by XP bar addons like Titan Panel and XP tracking WeakAuras.
Cap gossipPois_ at 200 entries (both gossip POI and quest POI paths) to
prevent unbounded memory growth from rapid gossip/quest queries. Add soft
240 FPS frame rate limiter when vsync is off to prevent 100% CPU usage —
sleeps for remaining frame budget when frame completes in under 4ms.
Returns (usable, noMana) tuple. Checks if the spell is known and not on
cooldown. Accepts spell ID or name. Used by action bar addons and
WeakAuras for conditional spell display (greyed out when unusable).
IsInInstance() returns whether player is in an instance and the type.
GetInstanceInfo() returns map name, instance type, difficulty index/name,
and max players. GetInstanceDifficulty() returns 1-based difficulty index.
Critical for raid/dungeon addons like DBM for instance detection.
Returns WoW-standard classification strings: "normal", "elite", "rareelite",
"worldboss", or "rare" based on creature rank from CreatureCache. Used by
nameplate addons (Plater, TidyPlates) and boss mods (DBM) to detect elite/
boss/rare mobs for special handling.
Add playMinimapPing() to UiSoundManager with MapPing.wav (falls back to
target select sound). Play the ping sound in MSG_MINIMAP_PING handler
when the sender is not the local player. Provides audio feedback for
party member map pings, matching WoW behavior.
GetGameTime() returns server game hours and minutes from the day/night
cycle. GetServerTime() returns Unix timestamp. UnitXP("player") and
UnitXPMax("player") return current and next-level XP values. Used by
XP tracking addons and time-based conditionals.
Add setZoneName() to LoadingScreen and display the map name from Map.dbc
as large gold text with drop shadow above the progress bar. Shown in both
render() and renderOverlay() paths. Zone name is resolved from gameHandler's
getMapName(mapId) during world load. Improves feedback during zone transitions.
Mirror the zone-transition cleanup in disconnect(): fire despawn callbacks
for all entities before clearing the entity manager. Prevents M2 instances
and character models from leaking when the player disconnects and reconnects
quickly (e.g., server kick, network recovery).
handleNewWorld() previously called entityManager.clear() directly without
notifying the renderer, leaving stale M2 instances and character models
allocated. Now iterates all entities and fires creatureDespawnCallback,
playerDespawnCallback, and gameObjectDespawnCallback before clearing.
Also clears player caches (visible items, cast states, aura cache,
combat text) to prevent state leaking between zones.
The expirationTime field (7th return value of UnitBuff/UnitDebuff/UnitAura)
was hardcoded to 0. Now returns GetTime() + remaining seconds, matching
WoW's convention where addons compute remaining = expirationTime - GetTime().
Enables buff/debuff timer addons like OmniCC and WeakAuras.
The caster field (8th return value) was always nil. Now returns the
caster's unit ID ("player", "target", "focus", "pet") or hex GUID
string for other units. Enables addons to identify who applied a
buff/debuff for filtering and tracking purposes.
