Replace PlaySound no-op stub with a real implementation that maps
WoW sound IDs and names to the UiSoundManager methods:
By ID: 856/1115→button click, 840→quest activate, 841→quest complete,
862→bag open, 863→bag close, 888→level up
By name: IGMAINMENUOPTION→click, IGQUESTLISTOPEN→quest activate,
IGQUESTLISTCOMPLETE→quest complete, IGBACKPACKOPEN/CLOSE→bags,
LEVELUPSOUND→level up, TALENTSCREEN→character sheet
This gives addons audio feedback when they call PlaySound() — button
clicks, quest sounds, and other UI sounds now actually play instead
of being silently swallowed.
Implement core vendor query functions from ListInventoryData:
- GetMerchantNumItems() — count of items for sale
- GetMerchantItemInfo(index) — name, texture, price, stackCount,
numAvailable, isUsable for each vendor item
- GetMerchantItemLink(index) — quality-colored item link
- CanMerchantRepair() — whether vendor offers repair service
Enables auto-sell addons (AutoVendor, Scrap) to read vendor inventory
and check repair capability. Data sourced from SMSG_LIST_INVENTORY
via currentVendorItems + itemInfoCache for names/icons.
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).
SetAction's item branch and SetHyperlink's item/spell branches
showed only the item name, ignoring the full tooltip system we built.
SetAction item path now uses _WoweePopulateItemTooltip (shows armor,
stats, damage, bind type, sell price etc.).
SetHyperlink item path now uses _WoweePopulateItemTooltip; spell
path now uses SetSpellByID (shows cost, range, cast time, cooldown).
This means shift-clicking an item link in chat, hovering an item on
the action bar, or viewing any hyperlink tooltip now shows the full
stat breakdown instead of just the name.
SetSpellByID now shows comprehensive spell information:
- Mana/Rage/Energy/Runic Power cost
- Range in yards (or omitted for self-cast)
- Cast time ("1.5 sec cast" or "Instant")
- Active cooldown remaining in red
Uses existing GetSpellInfo (castTime, range from DBC), GetSpellPowerCost
(mana cost from DBC), and GetSpellCooldown (remaining CD) to populate
the tooltip with real spell data.
Item tooltips now display the vendor sell price at the bottom, formatted
as "Sell Price: 12g 50s 30c". Uses the vendorPrice field from GetItemInfo
(field 11, sourced from SMSG_ITEM_QUERY_SINGLE_RESPONSE sellPrice).
Helps players quickly assess item value when looting or sorting bags.
Extend item tooltips with secondary stats and resistances:
- Extra stats from ItemQueryResponseData.extraStats: Hit Rating,
Crit Rating, Haste Rating, Resilience, Attack Power, Spell Power,
Defense Rating, Dodge/Parry/Block Rating, Expertise, Armor Pen,
Mana/Health per 5 sec, Spell Penetration — all in green text
- Elemental resistances: Fire/Nature/Frost/Shadow/Arcane Resistance
Also passes extraStats as an array of {type, value} pairs and
resistance fields through _GetItemTooltipData for Lua consumption.
Stat type IDs follow the WoW ItemMod enum (3=Agi, 7=Sta, 31=Hit,
32=Crit, 36=Haste, 45=SpellPower, etc.).
Enhance _WoweePopulateItemTooltip to show complete item information:
- Bind type (Binds when picked up / equipped / used)
- Armor value for armor items
- Weapon damage range, speed, and DPS for weapons
- Primary stats (+Stamina, +Strength, +Agility, +Intellect, +Spirit)
in green text
- Required level
- Flavor/lore description text in gold
Backed by new _GetItemTooltipData(itemId) C function that returns a
Lua table with armor, bindType, damageMin/Max, speed, primary stats,
requiredLevel, and description from ItemQueryResponseData.
Replace minimal name-only item tooltips with proper WoW-style display:
- Quality-colored item name header
- Item level line for equipment (gold text)
- Equip slot and weapon/armor type on a double line
(e.g., "Head" / "Plate" or "One-Hand" / "Sword")
- Item class for non-equipment items
Shared _WoweePopulateItemTooltip() helper used by both
SetInventoryItem and SetBagItem for consistent tooltip formatting.
Maps INVTYPE_* strings to display names (Head, Chest, Two-Hand, etc.).
GetItemInfo returned empty strings for item class (field 6), subclass
(field 7), and equip slot (field 9). Now returns:
- Class: mapped from itemClass enum (Consumable, Weapon, Armor, etc.)
- Subclass: from parsed subclassName (Sword, Mace, Shield, etc.)
- EquipSlot: mapped from inventoryType to INVTYPE_ strings
(INVTYPE_HEAD, INVTYPE_CHEST, INVTYPE_WEAPON, etc.)
These fields are used by equipment comparison addons, character sheet
displays, and bag sorting addons to categorize and filter items.
Four independent static local steady_clock start times were used as
time origins in GetTime(), GetSpellCooldown(), UnitBuff expiration,
and UnitCastingInfo — each initializing on first call at slightly
different times. This created systematic timestamp mismatches.
When addons compute (start + duration - GetTime()), the start value
from GetSpellCooldown and the GetTime() return used different epochs,
causing cooldown sweeps and buff timers to appear offset.
Replace all four independent statics with a single file-scope
kLuaTimeEpoch constant and luaGetTimeNow() helper, ensuring all
time-returning Lua functions share exactly the same origin.
Implement GetBindingKey(command) and GetBindingAction(key) with
default action button mappings (ACTIONBUTTON1-12 → "1"-"9","0","-","=").
Action bar addons display bound keys on button tooltips via
GetBindingKey("ACTIONBUTTON"..slot).
Also add stubs for GetNumBindings, GetBinding, SetBinding, SaveBindings,
SetOverrideBindingClick, and ClearOverrideBindings to prevent nil-call
errors in FrameXML keybinding UI code (37 call sites).
GetSpellCooldown only returned per-spell cooldowns from the
spellCooldowns map, ignoring the Global Cooldown. Addons like OmniCC
and action bar addons rely on GetSpellCooldown returning GCD timing
when no individual spell cooldown is active — this is what drives the
cooldown sweep animation on action bar buttons after casting.
Now falls back to GCD timing (from getGCDRemaining/getGCDTotal) when
the spell has no individual cooldown but the GCD is active. Returns
proper (start, duration) values so addons can compute elapsed/remaining.
Same fix applied to GetActionCooldown for spell-type action bar slots.
Implement keyboard modifier state queries using ImGui IO state:
- IsShiftKeyDown, IsControlKeyDown, IsAltKeyDown — direct key queries
- IsModifiedClick(action) — checks if the modifier matching a named
action is held (CHATLINK/SPLITSTACK=Shift, DRESSUP=Ctrl, SELFCAST=Alt)
- GetModifiedClick(action) — returns the assigned key name for an action
- SetModifiedClick — no-op stub for compatibility
These are fundamental input functions used by virtually all interactive
addons: shift-click to link items in chat, ctrl-click for dressup,
alt-click for self-cast, shift-click to split stacks, etc.
GetItemInfo returned item links with hardcoded white color (|cFFFFFFFF)
regardless of quality. Now uses quality-appropriate colors: gray for
Poor, white for Common, green for Uncommon, blue for Rare, purple for
Epic, orange for Legendary, gold for Artifact, cyan for Heirloom.
Also fix GameTooltip:GetItem() to use the quality-colored link from
GetItemInfo instead of hardcoded white.
GetRaidRosterInfo(index) returns name, rank, subgroup, level, class,
fileName, zone, online, isDead, role, isML — the core function raid
frame addons (Grid, Healbot, VuhDo) use to populate unit frame data.
Resolves class from UNIT_FIELD_BYTES_0 when entity is available.
GetThreatStatusColor(status) returns RGB for threat indicator coloring
(gray/yellow/orange/red). Used by unit frames and threat meters.
GetReadyCheckStatus(unit) stub returns nil (no check in progress).
RegisterUnitWatch/UnregisterUnitWatch stubs for secure frame compat.
GetItemQualityColor(quality) returns r, g, b, hexString for item
quality coloring (Poor=gray through Heirloom=cyan). Used by bag
addons, tooltips, and item frames to color item names/borders.
GetItemCount(itemId) counts total stacks across backpack + bags.
Used by addons to check material availability, quest item counts,
and consumable tracking.
UseContainerItem(bag, slot) uses/equips an item from a container
slot, delegating to useItemById for the actual equip/use action.
Add the complete cursor state machine needed for drag-and-drop:
- PickupAction(slot) — pick up or swap action bar slots
- PlaceAction(slot) — place cursor content into action bar
- PickupSpell / PickupSpellBookItem — drag spells from spellbook
- PickupContainerItem(bag, slot) — drag items from bags
- PickupInventoryItem(slot) — drag equipped items
- ClearCursor / DeleteCursorItem — clear cursor state
- GetCursorInfo — returns cursor content type/id
- CursorHasItem / CursorHasSpell — query cursor state
- AutoEquipCursorItem — equip item from cursor
Cursor state tracks type (SPELL/ITEM/ACTION), id, and source slot.
PickupAction on empty slots with a spell cursor auto-assigns spells
to the action bar. Enables spellbook-to-action-bar drag-drop and
inventory management through the WoW UI.
Implement the core map functions needed by WorldMapFrame.lua:
- SetMapToCurrentZone — sets map view from player's current mapId/zone
- GetCurrentMapContinent — returns continent (1=Kalimdor, 2=EK, etc.)
- GetCurrentMapZone — returns current zone ID
- SetMapZoom(continent, zone) — navigate map view
- GetMapContinents — returns continent name list
- GetMapZones(continent) — returns zone names per continent
- GetNumMapLandmarks — stub (returns 0)
Maps game mapId (0=EK, 1=Kalimdor, 530=Outland, 571=Northrend) to
WoW's continent numbering. Internal state tracks which continent/zone
the map UI is currently viewing.
Replace empty stub GameTooltip methods with working implementations:
- SetInventoryItem(unit, slot): populates tooltip with equipped item
name and quality-colored text via GetInventoryItemLink + GetItemInfo
- SetBagItem(bag, slot): populates from GetContainerItemInfo + GetItemInfo
- SetSpellByID(spellId): populates with spell name/rank from GetSpellInfo
- SetAction(slot): delegates to SetSpellByID or item lookup via GetActionInfo
- SetUnitBuff/SetUnitDebuff: populates from UnitBuff/UnitDebuff data
- SetHyperlink: parses item: and spell: links to populate name
- GetItem/GetSpell: now return real item/spell data when tooltip is populated
Also fix GetCVar/SetCVar conflict — remove Lua-side overrides that
were shadowing the C-side implementations (which return real screen
dimensions and sensible defaults for common CVars).
Implement GetNumQuestLeaderBoards and GetQuestLogLeaderBoard — the core
functions WatchFrame.lua and QuestLogFrame.lua use to display objective
progress like "Kobold Vermin slain: 3/8" or "Linen Cloth: 2/6".
GetNumQuestLeaderBoards counts kill + item objectives from the parsed
SMSG_QUEST_QUERY_RESPONSE data. GetQuestLogLeaderBoard returns the
formatted progress text, type ("monster"/"item"/"object"), and
completion status for each objective.
Also adds ExpandQuestHeader/CollapseQuestHeader (no-ops for flat quest
list) and GetQuestLogSpecialItemInfo stub.
GetPlayerFacing() returns player orientation in radians, needed by
minimap addons for arrow rotation and facing-dependent mechanics.
GetCVar(name) returns sensible defaults for commonly queried CVars
(uiScale, screen dimensions, nameplate visibility, sound toggles,
autoLoot). SetCVar is a no-op stub for addon compatibility.
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.
Implement the quest tracking functions needed by WatchFrame.lua:
- SelectQuestLogEntry/GetQuestLogSelection — quest log selection state
- GetNumQuestWatches — count of tracked quests
- GetQuestIndexForWatch(watchIdx) — map Nth watched quest to log index
- AddQuestWatch/RemoveQuestWatch — toggle quest tracking by log index
- IsQuestWatched — check if a quest log entry is tracked
- GetQuestLink — generate colored quest link string
Backed by existing trackedQuestIds_ set and questLog_ vector.
Adds selectedQuestLogIndex_ state to GameHandler for quest selection.
Maps WoW equipment slot names (e.g. "HeadSlot", "MainHandSlot") to
inventory slot IDs, empty-slot textures, and relic check flags.
Supports case-insensitive matching with optional "Slot" suffix stripping.
Unblocks PaperDollFrame.lua and BankFrame.lua which call this function
to resolve slot button IDs during UI initialization.
IsActionInRange(slot) checks if the spell on an action bar slot is within
range of the current target, using DBC spell range data and entity positions.
Returns 1/0/nil matching the WoW API contract.
GetActionInfo(slot) returns action type ("spell"/"item"/"macro"), id, and
subType for action bar interrogation by bar addons.
GetActionCount(slot) returns item stack count across backpack and bags for
consumable tracking on action bars.
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.
Returns squared distance between the player and a unit, plus a boolean
indicating whether the calculation was possible. Squared distance
avoids sqrt for efficient range comparisons.
Used by DBM, BigWigs, and proximity warning addons for raid encounter
range checks (e.g., "spread 10 yards" mechanics).
Returns true if the player is within interaction distance of a unit:
- Index 1: Inspect range (28 yards)
- Index 2: Trade range (11 yards)
- Index 3: Duel range (10 yards)
- Index 4: Follow range (28 yards)
Used by trade addons, inspect addons, and proximity detection addons.
Returns 1 if the spell can reach the target, 0 if out of range, nil
if range can't be determined. Compares player-to-target distance against
the spell's maxRange from Spell.dbc via SpellDataResolver.
Used by healing addons (Healbot, VuhDo, Clique) to check if heals can
reach party members, and by action bar addons for range coloring.
Returns true when the unit's entity exists in the entity manager
(within UPDATE_OBJECT range). Unlike UnitExists which falls back to
party member data, UnitIsVisible only returns true for entities that
can actually be rendered on screen.
Used by nameplate addons and proximity addons to check if a unit is
within visual range.
Session 14 commit #100: 95 new API functions, 113 new events.
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.
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.
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.
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 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.
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.
Implement GetAddOnMetadata(addonNameOrIndex, key) which reads arbitrary
TOC file directives. All directives are now stored in the addon info
registry table under a "metadata" sub-table.
This enables addons to read their own version, author, X-* custom
fields, and other TOC metadata at runtime. Used by addon managers,
version checkers, and self-updating addons.
