To do

Fixed: aura visuals missing after loading (2026-10-15)

Saving marks effect objects (cObjectFX) dead; loading keeps the buff but drops the aura effect (type 842) that follows the hero. src/mods/aura_restore.cpp recreates it after a load for Heldenmut (0x3f7) and Klingenblick (0x3f8). Spell auras (Steinhaut, Lichtschild, ...) use other effects; the user confirmed on 2026-10-17 that their visuals are back after loading too.

Data-driven arts instead of hardcoded art ids

Asked 2026-10-15: naming single arts as constants (kArtHeldenmut, kArtFlammenwerfer, ... in src/game/engine/arts.h) does not scale. Mods should decide by an art's properties, read from the game's own data:

• the definition tables g_spellDefs (0x950a38, 71 x 0x94) and g_combatMoveDefs (0x94ddb0, 95 x 0x78): id, icon name, launch type, usable mounted, ... (tools/arttable.mjs dumps them; most fields unnamed);
• map the remaining fields (regeneration group, lasting effect / aura, duration, ...) and expose them as an ArtInfo lookup in src/game/;
• where the game itself hardcodes ids (e.g. the arts that always count as magic in cCreatureArts::AddGroupRegen, the "already active" switch in IsValidArtTarget), keep one table of those ids with the reason, instead of named constants spread over the mods;
• optionally an own data file (JSON next to the DLL) for mod-side settings per art, if we need values the game does not have.

Art ranges: scaling and indicators

Asked 2026-10-15 (after making periodic aura hits strike everything in range, docs/aura-hits.md):

• art ranges should scale with the art's level, and possibly with new attributes;
• possibly show a range indicator (e.g. a ring around the hero for auras, or at the cursor for aimed arts).

Known so far: the periodic-hit aura (effect kind 0x12) uses (cCreatureArts +0x56 + 20) * 10 world units, measured from the owner with cCreature::DistanceTo (0x536f20); what +0x56 is (level? a stat?) is not mapped yet. Other arts' ranges are not mapped. Fits the data-driven arts item above (range as a property of an art, one place to compute it).

Rename life leech to "omnivamp"

Asked 2026-10-15: life leech (property 0x349, "Lebensentzug") becomes "omnivamp". To do: the in-game texts (item property, tooltips, character window). The leech code is the game's (0x5707a4.., property 0x349, in the damage code 0x56aff0); it credits the hit's attacker (order +0x1c). Omnivamp usually means healing from all damage, not only weapon hits: aura hits (docs/aura-hits.md) now name their attacker so the game applies it; other damage sources (spells, combat arts' extra hits, damage over time) may follow.

Map and map zoom in widened views

Reported 2026-10-15: the map (and zooming it) does not support the widened render sizes yet. 2026-10-16: TAB map fixed (viewport shifted), M map spans the render width (docs/hud.md, "Large map"), zoomed view and its markers included. Confirmed in-game 2026-10-16.

Quest dialog glitches in widened views

Reported 2026-10-15: accepting a quest, the dialog window "kept glitching" and button clicks were not detected correctly. Probably the HUD layer (src/mods/hud.cpp: windows shifted while they render / handle events): the dialog may not be covered, or shifted twice. Details asked from the user.

WASD walks around walls (caves)

Reported 2026-10-15: in caves WASD movement behaves "as if the player tries to find another way to the target location if a wall comes up". WASD sends a walk order to a point 300 world units ahead (docs/wasd.md); when that point is behind a wall the pathfinder plans a detour. Idea: find the game's straight line / walkability check and shorten the target when the line is blocked (or stop / slide along the wall). Related to the pathfinder item above.

Esc closes an open dialog first

Asked 2026-10-15: with any dialog open (quest, trader, inventory, ...), Esc should close that dialog instead of opening the game menu (ESC menu, cUI_EscMenu). Esc is handled in the engine / UI manager hotkeys (docs/wasd.md: engine 0x618130, UI manager 0x757120).

In-DLL smoke tests (later)

A test mode inside the mod DLL, started by an ini setting or command-line flag, so builds can be checked without play-testing and without driving the real mouse/keyboard like tools/autotest-load.ps1:

1. load a fixed test save;
2. play scripted input through the existing hooks (keys, casting arts, weapon set switches, save + reload);
3. take back-buffer screenshots at checkpoints and log checks to sacred_re.log (aura effect present after reload, slot 6-7 inventories survive a save, ...);
4. exit the game.

Better pathfinder (mouse clicks and monsters)

Replace the game's pathfinding with a more reliable and efficient one, for click-to-move and for monster AI. What we know so far:

• Walk orders are cEvent_creature command 4 with a ground target (+0x18/+0x1c), sent through cEngine::SendCreatureOrder (0x6170d0), which snaps the target to a walkable point (0x616b70) and hands it to cCreature::ReceiveOrder (0x52e400, vf18, ~6400 decompiled lines).
• Far targets (~2000 world units) are rejected or followed badly.
• Still to map: the path search itself, the sector/tile collision data it reads, and how monster AI issues its moves.

Key bindings moved for WASD movement (temporary)

W, A and S were game hotkeys. With WASD movement (src/mods/wasd.cpp) their actions moved to other keys for now; choose final bindings (and update the in-game texts/tooltips that name the old keys):

Key	Action	Temporary key (sacred_re.ini)
W	potion kind 3 (cEngine::UseActionSlot, like Q/E/R/B/Space)	game potion keys switched off; [keys] Potion1-5 (docs/options.md)
A	pick up items nearby (creature event 0x113)	Q ([keys] PickUp, 2026-10-17; was V)
S	save game window (UI_WND_SAVEGAME)	K ([keys] SaveGame)
D	unbound	-

Globally bound letters (engine 0x618130, UI manager 0x757120): A B C E F H I L M N O P Q R S T W, Space, ^, digits. Individual windows may use more.

Potion stacks

Asked 2026-10-17 (after the potion counts on the bottom bar, src/mods/potioncounts.cpp): potions of the same type (e.g. minor healing) stack in one inventory cell, up to 20 per stack (a full stack starts a new one). Drag, sell and drop move the whole stack, as with any other item. The counts on the potion slots then add up the stacks. In progress, see docs/item-stacks.md (open: sale price per stack, splitting on the ground).

Walking animation after loading (2026-10-17)

The hero sometimes plays a walking animation after a save game load while standing still. Not reproduced yet: a load log (hero mode, action, animation fields, orders) showed nothing unusual; right after a load the game itself sends one walk order (0x4) while the hero is idle. Measure again when it shows.
