- SF first-responder lock: after sending SR/LSR, only accept SF
messages from the first player to respond, ignore duplicates
from other members to prevent entity flicker.
- Roster change debounce: retriggerable 5s timer with up to 5
one-second extensions (10s max). Only fires on group size
increase. Party events skipped when in raid.
- Area ID check in DLL respawn: markers only spawn when the
player is in the same zone (area_id match against 0xB4E314).
- New GetCurrentAreaId() Lua function for addon zone awareness.
- SR handler no longer requires sender permission (anyone can ask for
marks). Split into SR (only leader/assist responds) and LSR (anyone
with defs responds, for leader relog recovery).
- Login sync uses 5s delayed timer so group roster is populated first.
- Timer cancelled if leader places a mark before it fires.
- SF (sync response) accepted from anyone without permission check.
- Colon delimiter instead of pipe to avoid WoW color escape errors.
Markers now survive zone transitions via persistent MarkerDef structs
(position + area ID) that are NOT cleared during world teardown. The
per-frame tick detects zombie entities (refcount <= 1 from game culling)
and respawns markers when the player approaches within 200 yards.
New DLL Lua APIs: SetMarkerDef, ClearMarkerDef, GetMarkerDef for the
addon to store/query definitions without immediate entity creation.
Addon layer adds group sync via CHAT_MSG_ADDON messages using colon-
delimited protocol (P:idx:x:y:z:area, C:idx, CA, SR, SF:...). Wraps
WorldMarker/ClearWorldMarker to broadcast on placement. Permission
model: raid leader/assist or party leader only.
Fix lua_pushnumber calling convention: Ghidra confirms it is thiscall
(ECX=L, f64 on stack [EBP+8]/[EBP+0xc], ret 8), not fastcall. The
patched inreg fastcall was shoving the f64's low dword into EDX,
producing garbage values like 1.17e-250 from 1810.
- Hook OnWorldUpdate (0x482EA0) for per-frame tick while world is active
- Remove Lua OnUpdate animation driver (ProcessMarkerAnimations)
- Add DistanceToMark(index) Lua API returning player-to-marker distance
- Track marker positions DLL-side for distance queries
- Clean up positions on marker clear and world teardown
The marker cleanup hook on CleanupWorldAndEntities was never installed —
markers.installHooks() was missing from install() in main.zig. Entities
created via WorldMarker were never cleaned up before the game's atexit
handler iterated the hash table over freed heap memory.
Key changes:
- Add markers.installHooks() call (the actual crash fix)
- Replace manual install/uninstall/shutdown lists with a single modules
table that drives all three phases — prevents this class of bug
- Gate marker Lua functions, addon, and keybindings behind isActive()
so they're skipped when another DLL owns the hooks
- Add world_cleanup_hook.detach() to removeHooks() (was missing)
- Migrate from vendored libs/hook to external zhook dependency
- Unify installHooks return types to void across all modules
- Add diagnostic logging to marker cleanup (temporary, for testing)
5 marker slots (Yellow, Cyan, Green, Purple, Red) with placement
by coords, unit ID, or cursor position (stubbed pending terrain
offset research). Key bindings for all 5 markers + clear all.
Markers are now created via the game's high-level entity factory (0x6707c0)
which handles spatial registration, render setup, and lifecycle internally.
Removed ~300 lines of dead code: manual game object list insertion, A/B mode
switching, parity scanning, and model attachment wrappers.
Creation works (markers visible). Destruction still crashes — needs correct
destructor for entities created via CreateWorldUnit path (not DestroyWorldObjectAndRelease).
Markers: client-side world object system using CreateGameObject. Places
M2 models at arbitrary world positions via Lua commands (/mark test,
/mark pos). Includes embedded addon, xyz.m2/blp assets served from DLL
memory, position helpers from unit movement struct, and object lifecycle
management (create, cleanup, reposition, alpha, animation).
Framecrash: stub module with reference to crash at 0x007A2452.
Console: debug output via AllocConsole/WriteConsoleA, compiles out
entirely in non-Debug builds. Used by markers and file serve logging.
Build: markers added to feature flag matrix and all-variants step.
Main: conditional markers import, Lua function registration, embedded
addon + asset file serving, console init/deinit lifecycle.
Outline README: added misc planned features and debug mode notes.
