Extract duplicated WoW 1.12.1 addresses and game accessor functions
into shared modules (src/offsets.zig, src/wow.zig), replacing 5+
copies of getObjectByGUID, isInBattleground, isValidPtr, etc.
- src/offsets.zig: shared address constants (object manager, descriptor
fields, map/zone, core function addresses, D3D9/GX)
- src/wow.zig: shared accessor functions (pointer validation, object
manager traversal, field reads, unit helpers, battleground detection,
game function wrappers, raid target cache)
- Update 10 modules to import from shared instead of inline constants
- Remove outline/wow.zig (promoted to src/wow.zig)
- Trim outline/offsets.zig and markers/offsets.zig to module-specific only
Replace console.zig with logging.zig: per-module Logger with auto
[name] prefix, optional file output, and destination routing. Convert
all modules from manual [name] prefixes and global con.print to Logger
instances. Remove redundant "Module loaded" lines. Replace
OutputDebugStringA in outline/tracker with Logger. Add dpslog module
with structured combat log events (SPELL_DMG, PERIODIC, HEAL, MELEE).
Add clickthrough module and bigcursor D3D9 cursor scaling.
Replace all local calling convention declarations (const fc/tc/sc)
with hook.cc.fastcall/thiscall/stdcall from zhook. Migrate remaining
17 hook.fastcall() inline asm call sites to hook.call() with typed
function pointers.
Replace hand-written inline asm blocks with hook.call() typed function
pointer dispatch across 10 files. Also migrates 4 D3D9 COM vtable
NULL-dispatch blocks using ?*anyopaque optional pointers.
Net removal: ~350 lines of inline asm replaced by single-line calls.
Remove the embedded Screenshot addon (TOC + Lua) and WeirdUtilsScreenshot()
Lua function. Compression quality is now controlled entirely via a CVar
(saved to config.wtf), read fresh on each screenshot. CVar 0 disables PNG
and falls through to original TGA.
Prefix all addon folder names with WeirdUtils_ to avoid collisions
with real addons. Rename SavedVariables global from UI_MinimapIcons
to WeirdUtils_MinimapIconsSettings.
Hook ObjectEnumProc, RenderObjectBlips, and EnumVisibleObjects to classify
visible objects by NPC flags / GO type and render custom blip icons.
Includes Lua API (SetObjectTypeBlip), texture caching, WMO indoor/outdoor
filtering, and coordinate projection. Consolidate vendor subcategories
into single entry since vanilla only has one NPC_FLAG_VENDOR. Spell
tracking entries now toggle off when clicked while active.
Fix: queryMapObjIDs was __fastcall (not __thiscall) — pushing 3 stack
args but RET 0x8 only cleaned 2, corrupting ESP and crashing.
The WeirdUtils core addon only provided /wu slash commands, a version
global, and a test function. Remove it along with the WeirdUtils
dependency from all module addon TOC files -- the DLL controls addon
load order directly so the dependency was cosmetic.
- dataassets module renamed to customassets everywhere (build flag,
source, DLL variant name, docs)
- Markers addon renamed to WorldMarkers (addon path, .toc, .lua,
Bindings.xml header, Lua globals, debug log prefix, mutex name)
- All 9 module mutexes now use WeirdUtils_ prefix to avoid
collisions with other DLLs in the same process
Root cause: hook.fastcall used "r" constraints + explicit MOV to set
ECX/EDX. LLVM can allocate "r" inputs to clobbered registers, causing
cross-assignment (ecx_in→EDX, edx_in→ECX) or function address stomping
when func lands in ECX/EDX. Debug works by luck (trivial regalloc);
Release optimizes aggressively and hits the conflicts.
Fix: explicit "{ecx}", "{edx}", "{eax}" register constraints in zhook
fastcall — compiler places values directly, no MOV needed, no ambiguity.
Also fix 9 inline asm blocks across main.zig, interact.zig,
screenshot.zig, markers.zig missing ECX/EDX clobbers after CALL
instructions. Without clobbers the optimizer assumes registers retain
input values after the call — stale reuse in release builds.
Other changes in this commit:
- Rename markers→worldmarkers (build flag, DLL, Lua table)
- Rename assetfix→looseassets
- lua.zig: add .never_tail to pushcclosure, pcall, openlib, pushnumber
- Move internal marker functions into WorldMarkers Lua table via openlib
- Remove unused GetCurrentAreaId function
- Fix cleanup_file_handle_hook.original() → .callOriginal()
Marker definitions (position + area ID) now persist across zone
transitions. Entities are destroyed on map change but respawned
automatically when the player approaches within 200y. Definitions
are cleared on logout/exit via onShutdown hook.
Group sync via addon messages (WMark prefix, colon-delimited protocol)
with permission checks (raid leader/assist, party leader). Includes
sync request/response for late joiners and roster change broadcasting.
Fix lua_pushnumber calling convention: function is __thiscall (ECX=L,
f64 on stack, ret 8), not __fastcall. The patched inreg fastcall was
placing the f64's low dword in EDX, corrupting values.
Other fixes:
- Remove Bindings.xml from .toc files (explicit binding loader needed)
- Remove remove_on_shutdown for markers (was killing hooks on logout)
- Remove diagnostic entity check code (culling behavior understood)
- New Lua APIs: SetMarkerDef, ClearMarkerDef, GetMarkerDef
- Rename binding labels to marker colors
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)
Assetfix: hook CheckFileExistence to serve loose Data\ files. The original
flags|1 approach failed because game paths contain backslashes, causing
CheckFileExistence to skip BuildFilePath and check the raw path (no Data\
prefix). Fix: write the correct Data\-prefixed disk path to the output buffer
directly and return 1, bypassing the original function for hash map hits.
This preserves hook chaining (filename argument is never transformed).
Also adds transmogfix (transmog update coalescing), minimapicons (stub),
new build options for all three modules, mutex-based multi-DLL safety,
embed .skin data into .m2 models, and various module improvements.
Hook 5 intercepts loadModelFromFileAsync (0x71d4e0) to synchronously load M2
model data for fake in-memory file contexts. processLoadedModelData returns 1
and entities are created, but file context cleanup is currently skipped (leaks
0x60 bytes per load) due to a crash in the cleanup path, and there's a later
EIP=0 crash during the game main loop that needs investigation.
Also adds: combatlog module stub, framecrash anchor vtable hooks (GetRelativeTo
and GetWidth/GetHeight crash guards), embedded Raid_UI_FX model assets with
skins and textures, WU_XYZ debug model.
- Each module (outline, interact, screenshot) now has its own addon/
subdir with .toc, .lua, and Bindings.xml
- Core WeirdUtils addon lives in src/core/addon/
- build.zig supports compile-time feature gating via -D options
- main.zig uses build_options for conditional imports and addon embedding
- Module addons only load when their module is compiled in
- 'zig build all-variants' produces full.dll + 3 single-module DLLs
