libhealth ships with pfUI and Nampower's GetUnitField (hard-dep) covers
the real-HP read; the MobHealth integration was a chained last-resort
fallback that could never actually win, and on the nameplate path it
also mixed percentage and real-value scales into the bar's SetMinMaxValues
since it overwrote hp/hpmax without hpmin.
GUID is the unique identity; the name check was leftover from the
name-only era and became dead weight once cachedGuid (NAME_PLATE_UNIT_
ADDED) was added alongside it.
The plate-reuse reset only cleared name/guid/player/cdCache, leaving
hp/hpmax/rgb/namecolor/levelcolor/target/mouseover/inCombat behind. The
PERF gates downstream ("only update X when X changed") then skipped bar
fill / color / text updates when the new occupant happened to share a
cached value with the previous one — most easily reproduced on
plate-pool reuse in starting zones (mobs churn fast, percentage values
collide). Nuke the whole cache via table.wipe.
Refs #8.
ClassicAPI's recent C_Spell additions cover remote-unit casts natively
(SMSG_SPELL_START co-hook caching per caster GUID), so the two parallel
cast trackers pfUI was running — libcast.lua and the libdebuff_casts
table inside libdebuff.lua — can both retire.
Migrations:
- modules/castbar.lua: focus/player cast-info gathering reads
C_Spell.UnitCastingInfo / UnitChannelInfo directly. Fallback ladder
(libdebuff_casts → pfGetCastInfo → pfGetChannelInfo) collapses into a
single call. Pushback handlers stop writing back into a non-existent
cache; the local this.endTime is the source of truth.
- modules/nameplates.lua: GetCastInfo(guid) now resolves to a unit token
via UnitTokenFromGUID and queries C_Spell, returning the same compact
struct shape downstream code expected. UpdateCastbar collapses from a
three-branch hierarchy (dead IterDebuffs / libdebuff_casts / libcast)
to one C_Spell read.
- modules/afkcam.lua: pfGetCastInfo+pfGetChannelInfo round-trip becomes
a single C_Spell.UnitCastingInfo("player") or UnitChannelInfo fallback.
- libs/libpredict.lua: HealComm timing uses C_Spell on the sender's unit
token after a small group-roster walk to resolve the sender's name.
Deletions:
- libs/libcast.lua entirely (-571 lines) plus its init/libs.xml entry.
- libdebuff_casts / libdebuff_item_icons tables and their write sites
in libs/libdebuff.lua (the SPELL_START_*, SPELL_GO_*, SPELL_FAILED_*
event handlers stop maintaining them but keep firing the
libdebuff_*_hooks broadcast surface for actionbar / swingtimer /
libtotem). SPELLCAST_CHANNEL_STOP now reads the active channel from
C_Spell.ChannelInfo.
- modules/superwow.lua's supercast block — UNIT_CASTEVENT writes into
libcast.db are redundant now that C_Spell co-hooks the same packet.
- The cast-bar item-icon override that swapped in a potion/trinket
icon for item-triggered casts. Spell icon stays; the item-icon
metadata path (libdebuff_item_icons) went with libdebuff_casts.
Steady Shot synthetic cast bar — Turtle WoW-specific:
- castbar.lua gains a pfUI.synthetic_casts[unit] fallback that fires
only when C_Spell returns nil, so abilities the engine treats as
instant but which have a meaningful wait window can still render a
cast bar.
- modules/turtle-wow.lua replaces the old libcast.customcast block with
a Nampower SPELL_QUEUE_EVENT subscriber. ON_SWING_QUEUED matching
the localized "Steady Shot" name writes a 1.4s synthetic entry;
ON_SWING_QUEUE_POPPED clears it; castbar's endMs guard self-expires
the entry as a safety net. Note: haste scaling (libcast.ApplyShotHaste)
is gone — bar may finish slightly early under +ranged haste buffs.
Net: 152 insertions, 972 deletions.
With every external caller of libdebuff:UnitDebuff / :UnitOwnDebuff
now on C_UnitAuras, the two public per-aura readers and the
nameplate-side cache they were feeding have no consumers.
- libs/libdebuff.lua: removes libdebuff:UnitDebuff (~120 lines),
libdebuff:UnitOwnDebuff (~75 lines), the _ownDebuffSortFunc helper,
and the local cache table. The slotOwnership / ownDebuffs /
allAuraCasts / pendingCasts bookkeeping stays — GetBestAuraCast
(libpredict) and GetEnhancedDebuffs (CleveRoids) still read it, and
the event handlers maintain it. GetSlotCaster / GetDebuffSlotMap
stay too; the DEBUFF_ADDED_OTHER handler and the debug printer use
them. File goes 2010 → 1870 lines.
- modules/nameplates.lua: deletes PlateCacheDebuffs (was already
rewritten on C_UnitAuras and unused once the display loop bypassed
the cache), PlateUnitDebuff, the cachedVerify scaffolding, and the
nameplate.UnitDebuff / nameplate.CacheDebuffs registrations.
- api/config.lua + modules/gui.lua: drops the now-defunct
"guessdebuffs" knob — its only effect was gating the dead cache.
The per-unit cache reset only fired when the plate's name changed, so
pool reuse between same-named units (player "Ironforge Guard" → NPC
"Ironforge Guard") carried the previous unit's cache.player into the
next OnDataChanged call. GetUnitInfo then returned the wrong table's
class, unittype flipped to FRIENDLY_PLAYER, and the bar drew in MAGE
class color. Gate the reset on cachedGuid changes too.
Stores cache.player as true/false/nil instead of "PLAYER"/"NPC" so it
flows straight into GetUnitInfo as the isPlayer hint — both in
OnDataChanged and the wait_for_scan retry, which previously dropped
the hint and ping-ponged the flag every frame.
Hoists the name-change reset above the GetUnitInfo lookup and folds the
two UnitIsPlayer call sites into one. The earlier shape resolved
cache.player upfront from cachedGuid, then redundantly re-resolved from
unitstr after the name-change reset — and the upfront block could read
stale cache.player on plate reassignment, passing a wrong isPlayer hint
to GetUnitInfo.
GetUnitInfo() probed the players table first, so an NPC sharing a name
with a known player (e.g. Chromie) inherited the player's class, level,
and guild. Adds an isPlayer hint to GetUnitInfo and resolves each
plate's actual unit type from its cached GUID via UnitIsPlayer before
the lookup. The plate's cache.player gates further work.
Routes player and nameplate castbar progress through
PixelUtil.SetStatusBarValue so a 1.4s cast on a narrow bar no longer
shimmers across fractional pixels as it ticks. Adds GetMinMaxValues /
GetValue handlers to pfUI's custom StatusBar so PixelUtil can read the
current range.
Six allocation sites firing per visible plate per central tick (or per
throttled OnDataChanged tick) were generating heavy GC pressure visible
in pfDebug's analyzer:
- IterDebuffs callback in PlateCacheDebuffs was a fresh closure per call.
Hoisted to a module-level function with state in _pcdSelf / _pcdNow /
_pcdId, matching the pattern the icon-grid IterDebuffs already used.
- string.format("%.2f", remaining) in UpdateCastbar fired every frame per
active castbar. Factored into SetCastbarText helper that compares a
rounded integer (centi- or deci-seconds) and only formats + SetTexts
when the displayed value would actually change. lastTextTick reset
alongside lastEndTime so back-to-back casts don't collide.
- guid.."target" concat in GetCombatStateColor hit Lua's string intern
pool every call. Cached in guidTargetTokenCache, evicted alongside
the other per-guid caches in NAME_PLATE_UNIT_REMOVED.
- plate.name:SetText was unconditional; moved inside the existing
plate.cache.name change gate so it only fires on real unit changes.
- plate.level:SetText (string.format) was unconditional; gated behind a
new (level, elite) cache so the format only runs on level-up or
elite-state flips.
- C_NamePlate.GetNamePlates() poll every 0.5s allocated a fresh Lua
table just to read its length. Replaced with a visiblePlateCount
counter maintained event-driven from NAME_PLATE_UNIT_ADDED/_REMOVED.
- Switch the four GUID reads in OnDataChanged from plate.parent:GetName(1)
(SuperWoW idiom) to plate.cachedGuid (set by NAME_PLATE_UNIT_ADDED via
UnitGUID(token)). Move the initial OnDataChanged call out of
OnConfigChange's CREATE path so it runs after UNIT_ADDED has populated
cachedGuid; re-add it explicitly in the user-config-change loop.
- Reject GetUnitField's health/maxHealth when maxHealth == 100 — the
engine writes (hp_percent, 100) into UnitFields for non-detailed units
(UPDATE_PARTIAL packets carry percent only). Without this guard,
Nampower's raw field read returns the percent and the nameplate displays
"5 / 100" as if it were real HP. Mirrors libhealth's heuristic so we
fall through to its estimator instead.
- New config: nametextpos (LEFT/CENTER/RIGHT, defaults to CENTER).
Decouple the bar's anchor from the name so the name's JustifyH can
shift left/right without dragging the bar with it.
* nameplates: drive discovery + GUID lookup via C_NamePlate
ClassicAPI now provides the modern C_NamePlate API and the matching
NAME_PLATE_CREATED / NAME_PLATE_UNIT_ADDED / NAME_PLATE_UNIT_REMOVED
events. Replace the WorldFrame:GetChildren polling + manual GUID
dictionary with event-driven plumbing.
- Drop the per-tick WorldFrame:GetNumChildren / GetChildren scan
- Delete IsNamePlate() border-texture filter (events only deliver
nameplate frames)
- Delete the guidRegistry table + its OnShow/OnUpdate maintenance;
every lookup now goes through C_NamePlate.GetNamePlateForGUID
- Move per-GUID cache cleanup (debuffCache / threatMemory /
combatColorCache / libdebuff_casts) from the OnUpdate visibility
scan to a NAME_PLATE_UNIT_REMOVED handler — fires exactly once
per unit going out of range
- NAME_PLATE_CREATED drives nameplates.OnCreate; NAME_PLATE_UNIT_ADDED
sets cachedGuid and drives nameplates.OnShow (so OnCreate no longer
calls OnShow directly and no longer HookScripts the parent)
- visiblePlateCount uses table.getn(C_NamePlate.GetNamePlates())
Net -64 lines, with a meaningful reduction in per-tick CPU (no more
WorldFrame child iteration + region/texture filter every 50ms).
* nameplates: switch UNIT_ADDED/REMOVED handlers to nameplateN tokens
ClassicAPI's NAME_PLATE_UNIT_ADDED / _REMOVED events now ship the
"nameplateN" unit token as arg1 (matching modern WoW) instead of the
GUID string.
- UNIT_ADDED: resolve plate via C_NamePlate.GetNamePlateForUnit(arg1);
derive the cache-key GUID via UnitGUID(arg1)
- UNIT_REMOVED: same lookup pattern; compute UnitGUID(arg1) inside the
handler before the slot recycles (per docs guarantee)
The other six GetNamePlateForGUID call sites (libdebuff aura callbacks,
UNIT_FLAGS_GUID, PLAYER_TARGET_CHANGED, combo-point handler, castbar
frame) stay on the GUID flavor — they receive real GUIDs from other
event paths.

Changing parent from nameplate.health to plate allows raid icons to be shown even when nameplate health bar isn't shown.
Particularly useful if you have friendly nameplate healthbars disabled and friendlies have raid marks (e.g. tanks, marked player to stack on, etc)
Problem:
Since a recent Turtle-WoW update, nameplates would show the same castbar on all mobs sharing a name (e.g. multiple "Defias Rogue Wizard"). Additionally, a targeted mob that was not casting would incorrectly display the castbar of a nearby mob with the same name.
Changes:
**`modules/nameplates.lua`**
- Removed `hasNampower` version-sniffing entirely. Nampower is a hard requirement for pfUI; all related guards have been removed and the code runs unconditionally.
- Castbar lookup now always uses `nameplate.cachedGuid` directly — never `GetUnitGUID("target")` or a unit name string.
- Removed dead fallback block using `UnitCastingInfo("target")`.
- Restored fallback via `pfGetCastInfo(cachedGuid)` / `pfGetChannelInfo(cachedGuid)` (see libcast changes below) for casts not tracked by libdebuff (e.g. already-in-progress casts on login).
**`libs/libcast.lua`**
- Renamed `UnitCastingInfo` → `pfGetCastInfo` and `UnitChannelInfo` → `pfGetChannelInfo` to avoid confusion with the Blizzard API of the same name, which does not exist in Vanilla.
- Name-based fallback lookup (`libcast.db[unitName]`) is now skipped when a GUID is available. This prevents cast bleed between mobs that share a name.
**`libs/libpredict.lua`, `modules/castbar.lua`, `modules/afkcam.lua`**
- Updated all call sites to use the renamed `pfGetCastInfo` / `pfGetChannelInfo`.
Removed SuperWoW dependency from castbar and nameplate cast detection. Cast interrupts (sidestep, spell failed) now correctly stop the castbar by setting event = "FAIL" / event = "CAST" on the libdebuff cache entry instead of nil-ing it — preventing stale local references from keeping the castbar alive. UnitCastingInfo fallback is retained for non-Nampower environments but no longer overrides Nampower cast state.
Performance optimizations ported from experimental:
- libdebuff: replace 5s startup timer with next-frame defer
- libdebuff: use arg6 auraSlot directly (Nampower 2.29+) instead of GetDebuffSlotMap lookup
- libdebuff: invalidate slotMapCache on PLAYER_TARGET_CHANGED
- nameplates: detect Nampower 2.27.2+ for GUID-based nameplate lookup
Raidmarkers module ported from experimental:
- added raidmarkers.lua
- added config defaults and GUI section
- registered in modules.xml
focus.lua rework:
- removed CastSpellByNameNoQueue (Nampower's CastSpellByName now supports unit tokens/GUIDs natively)
- /focus Name: TargetByName with correct previous target restore + ClearTarget() fallback
- /focus Name: prefix match via SlashCmdList.TARGET when exact match fails
- suppress UI_ERROR_MESSAGE during targeting attempts
swingtimer fixes:
- non-Hunter ranged bar now fills left->right like MH/OH
- fix 1px artifact on Hunter bar center by using Hide() instead of SetWidth(0.1)
