totem: add GetTotemDuration(slot)

Returns the slot's active totem total duration in seconds (0 when none) — the totem's full lifetime from cast, same value as GetTotemInfo's 4th return, companion to GetTotemTimeLeft. Reads the tracker's durationMs. Verified in-game (constant 45 while time-left counts down).

+
+| Return | Meaning |
+|--------|---------|
+| `haveTotem` | `true` if the player carries the slot's **totem tool** (Fire/Earth/Water/Air Totem item) — the documented meaning, **not** whether a totem is summoned. |
+| `totemName` | The active totem spell's localized name (`""` when no totem is out — this is how you test "is a totem active"). |

+| `duration` | Total duration in seconds (`0` when none). |
+| `icon` | The active totem spell's icon texture path, or `nil` when none. |
+| `modRate` | Always `1` — vanilla has no per-totem haste. |
+| `spellID` | The active summon spell's ID (`0` when none). |

+
+Vanilla 1.12 has no client-side totem tracking (the totem bar,
+`PLAYER_TOTEM_UPDATE`, and `GetTotemInfo` are all TBC additions), so this
+is self-tracked but **data-driven**: the slot is read from the summon
+spell's `Spell.dbc` effect (`SUMMON_TOTEM_SLOT1..4` = Fire/Earth/Water/Air),
+duration from `SpellDuration.dbc`, the totem's creature entry (for death
+detection) from the effect's `EffectMiscValue`, and the `haveTotem` tool
+item from the spell's `Totem` field (the totem the spell requires) —
+resolved from the player's spellbook, not a hardcoded table. Casts are observed
+via the `SMSG_SPELL_GO` hook; a slot clears when its duration elapses OR
+when the totem creature disappears early (killed, Totemic Recall, or
+destroyed) — detected by scanning the object manager for the player-owned
+totem creature. Because it's data-driven, Turtle-custom totems are tracked
+automatically. Slot changes fire
+[`PLAYER_TOTEM_UPDATE`](#player_totem_update-event).
+
+### `GetTotemTimeLeft(slot)`
+
+Returns the seconds remaining before the slot's totem is auto-destroyed,
+or `0` when no totem is active in that slot. Slots: `1` Fire, `2` Earth,
+`3` Water, `4` Air.
+
+```lua
+local remaining = GetTotemTimeLeft(1)   -- Fire slot, e.g. 12.4
+```
+
+Computed from the same tracker as [`GetTotemInfo`](#gettoteminfoslot)
+(`startTime + duration − now`), so it shares that data's caveats — most
+notably it reflects the totem's *full* duration from cast, unaffected by
+any server-side early expiry the client isn't told about (the WorldTick
+scan still clears the slot when the totem creature actually disappears).
+
+### `GetTotemDuration(slot)`
+
+Returns the slot's active totem's **total** duration in seconds (its full
+lifetime from cast), or `0` when no totem is active. The companion to
+[`GetTotemTimeLeft`](#gettotemtimeleftslot) (remaining time) — same value
+as `GetTotemInfo`'s 4th return.
+
+```lua
+local total = GetTotemDuration(1)                       -- e.g. 60
+local frac  = GetTotemTimeLeft(1) / GetTotemDuration(1) -- bar fill

+Water, `4` Air). No-op when the slot has no active totem or the totem
+creature isn't currently visible in the client.
+
+```lua
+TargetTotem(2)   -- target your Earth totem

+//     totems self-classify.
+//   * CREATURE ENTRY is the effect's `EffectMiscValue` (the summoned
+//     totem's creature-template ID) — used to detect the totem's death.
+//   * DURATION is the summon spell's `SpellDuration.dbc` value (via the
+//     engine's own duration helper, so player duration mods apply).
+//
+// Detection: the player's totem cast fires SMSG_SPELL_GO, which
+// `Aura::Source` already co-hooks; it calls `OnPlayerSpellGo` here (before
+// its aura gate, since a summon applies no aura). We stamp the slot with
+// start time + duration.
+//
+// Death / removal: on WorldTick we scan the object manager for a
+// player-owned creature of the slot's entry. A "seen once, then gone"
+// latch clears the slot early (totem killed, Totemic Recall, or manually
+// destroyed) — the owner check (CreatedBy == player) means another

Author	SHA1	Message	Date
Brues	98b4ae14e7	totem: add GetTotemDuration(slot) Returns the slot's active totem total duration in seconds (0 when none) — the totem's full lifetime from cast, same value as GetTotemInfo's 4th return, companion to GetTotemTimeLeft. Reads the tracker's durationMs. Verified in-game (constant 45 while time-left counts down).	2026-07-20 21:27:58 -05:00
Brues	8d957eb424	totem: add TargetTotem(slot) Target the player's totem in a slot (1-4). Looks up the totem creature's live GUID (object-manager scan for the player-owned creature of the slot's tracked entry) and sets the target via FUN_00489a40 — the set-target-by-GUID path Script_TargetUnit uses after its token→GUID resolve. No-op when the slot is empty or the totem isn't visible. Added Offsets::FUN_TARGET_BY_GUID.	2026-07-20 21:25:34 -05:00
Brues	78618ea2cc	totem: add GetTotemTimeLeft(slot) Returns seconds remaining before the slot's totem auto-destroys (0 when no totem is active), computed from the existing Totem::Tracker's startMs + durationMs. Slots 1-4 = Fire/Earth/Water/Air. Verified in-game counting down.	2026-07-20 21:11:01 -05:00
Brues	1a4583e16e	totem: fire PLAYER_TOTEM_UPDATE on slot changes Backport the TBC PLAYER_TOTEM_UPDATE(totemSlot) event (absent from vanilla's table, so reserved as a custom event) on top of the existing Totem::Tracker. Every slot state change marks a dirty bit — the cast path (SpellGo), duration expiry, and the WorldTick death-scan removal — and OnTick flushes the dirty slots with Fire(id, "%d", slot). Flushing from the tick keeps Lua handlers out of mid-packet context. Drops fire next frame; removals within the ~250ms scan interval. Verified in-game.	2026-07-20 21:04:15 -05:00
Brues	a20e1206fb	totem: add GetTotemInfo(slot) with a self-tracking totem subsystem Vanilla 1.12 tracks nothing about totems client-side (the totem bar, PLAYER_TOTEM_UPDATE, and GetTotemInfo are all TBC additions), so Totem::Tracker tracks the four element slots itself — data-driven: - Slot from the summon spell's Spell.dbc effect (87-90 = SUMMON_TOTEM_SLOT1..4 = Fire/Earth/Water/Air; slot = effect - 86). - Creature entry from the effect's EffectMiscValue (for death detection). - Duration from SpellDuration.dbc via the engine duration helper. - haveTotem tool item from the spell's Totem[0] field (0xA0) — the totem the spell requires (a tool, not a consumed reagent) — resolved from the player's spellbook on SPELLS_CHANGED, not hardcoded. Casts are observed through Aura::Source's existing SMSG_SPELL_GO hook (a one-line notify before its aura gate, since a summon applies no aura) — no new hook, respects one-hook-per-target. Tool items resolve on SPELLS_CHANGED (a no-arg event via the shared Event::SignalHook), when the spellbook is populated. A slot clears when its duration elapses OR when the totem creature disappears early (killed / Totemic Recall / destroyed), detected by a throttled WorldTick object-manager scan for the player-owned creature of that entry (seen-then-gone latch; CreatedBy == player so another shaman's same-entry totem can't mask yours). GetTotemInfo returns haveTotem, totemName, startTime, duration, icon, modRate=1, spellID. Turtle-custom totems are tracked automatically. Also exposes Item::Count::InInventory (equipped + bags) as a shared helper for the tool-presence check. Verified in-game: Earthbind lands in slot 2, haveTotem reflects the Earth Totem tool, and Totemic Recall clears the slot early.	2026-07-20 20:53:01 -05:00
Brues	9f67cade87	unit: add UnitOwnerGUID(unit) Returns the GUID string of a unit's owner — the summoner of a pet/guardian/totem or the charmer of a charmed unit — or nil for players, world creatures, and unresolved units. Reuses Unit::Pet's existing OwnerGuid helper (CharmedBy, else CreatedBy in m_objectFields), the same field the pet predicates share. Verified in-game: UnitOwnerGUID('target') == UnitGUID('targetowner').	2026-07-20 18:35:47 -05:00
Brues	8629e13e1f	gameobject: add ClosestGameObjectPosition(gameObjectID) Returns xPos, yPos, distance for the nearest visible game object of a given GO-template ID, or nothing when none is in range — the game-object counterpart of ClosestUnitPosition. Extract the shared visible-object-manager scan into Object::ClosestByEntry (object/ClosestByEntry.{h,cpp}): enumerate visible objects, match GUID type + template entry (bits 24-47), return the closest one's world position + center distance. Both ClosestUnitPosition (TYPEMASK_UNIT / Creature) and ClosestGameObjectPosition (TYPEMASK_GAMEOBJECT / GameObject) are now thin wrappers over it; ClosestUnitPosition behavior is unchanged. Same retail-vs-vanilla caveat as the unit version: returns the nearest CURRENTLY-VISIBLE object rather than reading retail's static starting- zone database (which vanilla lacks). Documented in docs/API.md.	2026-07-20 18:26:46 -05:00
Brues	ca9bfbab5e	unit: add ClosestUnitPosition(creatureID) Returns xPos, yPos, distance for the nearest creature of a given NPC entry ID, or nothing when none is in range. Walks the visible-object manager (Loot::Nearby pattern), matches creatures whose GUID encodes the entry (bits 24-47, per guid/CreatureInfo), and returns the closest one's world position + center distance in yards. Semantic note: retail's ClosestUnitPosition reads a static client spawn database (starting-zone mobs only); vanilla 1.12 has none, so this returns the nearest CURRENTLY-VISIBLE creature of that entry (anywhere) — more general than retail, but can't point at un-synced spawns. Documented in docs/API.md.	2026-07-20 18:18:52 -05:00
Brues	8fdc767cc7	item: add Enum.ItemQuality Poor=0 through Artifact=6, matching the numeric quality GetItemInfo / C_Item.GetItemQuality report. Heirloom (7) and WoWToken (8) are omitted — no such items exist on 1.12. Registered in src/item/TypeInfo.cpp alongside Enum.ItemClass / Enum.InventoryType. Docs + README updated.	2026-07-20 17:36:47 -05:00
Brues	aa31c25be5	item: add GetItemClassInfo, GetItemSubClassInfo global, Enum.ItemClass - GetItemClassInfo(classID) -> localized ItemClass.dbc name, registered as both a global and C_Item.GetItemClassInfo. Obsolete class slots return the client's literal "...(OBSOLETE)" string. - GetItemSubClassInfo(classID, subClassID) exposed as a global (the C_Item form already existed); returns name + the armor-material bool. - Enum.ItemClass: 0..15 with modern key names on the obsolete slots (Gem/ItemEnhancement/CurrencyTokenObsolete/PermanentObsolete), plus post-vanilla 16..19 for parity, matching the Enum.InventoryType precedent in the same module. All added to src/item/TypeInfo.cpp alongside the existing subclass / inventory-type surface. Docs + README updated.	2026-07-20 17:27:28 -05:00
Brues	29aafe88f8	turtle: move combo-finisher & armor-healing custom data out of stock Two pieces of hardcoded Turtle-specific data were embedded in stock modules; relocate them to src/turtle/ behind extension points so the stock code carries only generic mechanism. - aura/ComboDuration: add an AutoDanglingResolver extension point; the stock module keeps the dangling-row detection + scaling formula, and Turtle's reworked-Rip base/max values move to src/turtle/ComboDuration.cpp. Not gated on Turtle::Detected() — the dangling-row condition stays the gate (gate on the bug, not the realm), preserving prior behavior exactly. - spell/BonusDamage: add a Spell::HealingAura resolver extension point; the stock GetSpellBonusHealing decoder keeps auras 135 (flat) and 175 (xSpirit), and Turtle's Ironclad aura 199 (xArmor) moves to src/turtle/HealingAura.cpp, gated on Turtle::Detected() (an aura index is a generic slot that could collide on another server). Behavior is unchanged on Turtle; both extractions are pure relocation.	2026-07-20 16:49:45 -05:00
Brues	461f15a4a6	item: derive bag family from (class, subclass) for bags with empty field Turtle's item data leaves m_bagFamily at 0 on the bags/quivers themselves — the four profession bags (Soul/Herb/Enchanting/ Engineering, Container class) and quivers/ammo pouches (Quiver class) all read 0, so C_Item.GetItemFamily and C_Container.GetContainerNumFreeSlots reported 0 for them even though the tooltip clearly shows "Soul Bag" etc. Recover the family from the item's class + subclass instead (keyed on class because subclass numbers repeat: Container sub 2 = Herb Bag, Quiver sub 2 = Quiver). Loot items keep carrying the field directly. Factored the derivation into a shared Item::BagFamily helper (BitmaskForRecord) used by both GetItemFamily and the free-slot functions, so a bag and the items it holds always agree on the family bit. Side effect: CalculateTotalNumberOfFreeBagSlots now correctly excludes specialty bags from the general free-slot total. Non-stock data lives in its own module: src/turtle/ with a TURTLE_WOW_VERSION-based Turtle::Detected() gate (no realm sniffing) and the custom Meat/Fish/Leather/Mining families (ItemBagFamily.dbc rows 10-13) plugged into Item::BagFamily via an AutoResolver extension point, so the stock table stays pure vanilla.	2026-07-20 16:38:42 -05:00
