- Shared chest: tabs "Truhe"/"Gemeinsam" as a column left of the grid (game tab sheet), grids placed every tick, persistent across heroes - Inventory tab texts capitalized (RegisterText / CapitalizeText) - Combat-art runes stack like potions (itemstack, renamed from potionstack) - Rune master: any rune for any number of runes, price by rune count (4 runes = 1,000, x10 per missing rune), bought rune goes into the backpack, Buy disabled without runes, gold or room, last rune remembered per hero (saved), the chosen rune's name below its icon, dropping a stack gives up one rune - Keys: the old key handling no longer takes over after the save screen (text field focus only counts while its dialog is shown) - Esc crash: tooltips forgotten when the game destroys them - Pick up (Q) sends the pickup order directly; search reach doubled - Kettenblitz: tooltip shows hits per chain, chains, cast and jump range; cast range 900 (longer ray segments), jumps half of that Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

# Shared chest
|
|
|
|
## Request (2026-10-17)
|
|
|
|
The chest gets a second tab that belongs to no single hero: a chest shared by
|
|
all characters. Decided: stored in one file in the save folder
|
|
(`save\shared_chest.json`), two tabs ("Truhe" / "Gemeinsam"), same size as the
|
|
chest (20 x 10). Potions stack in it like in every player inventory
|
|
(docs/item-stacks.md). Follow-up (same day): text tabs were barely visible;
|
|
use the inventory's Rucksack / Kampfkünste / Combos header look with its
|
|
selected state, stacked as a column from the grid's top-left. The shared chest
|
|
was empty after loading another character (in-game saves don't call saveHero).
|
|
|
|
## Measured / read
|
|
|
|
- The chest window `cUI_Chest` (constructor ends `0x6ac899`): +0x158 =
|
|
inventory 0x11 (the hero's chest), grid 20 x 10 from (window x, 20). Render
|
|
`0x6ac8b0` (vf14) draws +0x158 with `DrawItems`; HandleEvent `0x6acc70`
|
|
(vf10) does hit test, fit, place, swap and take via +0x158. Only Shift+click
|
|
uses the index: `cInventoryManager::MoveItem` `0x5dec80` (from, to, id, ?,
|
|
ret 0x10) from 0x11 to the hero.
|
|
- Chest saving: inventory 0x11 is chunk 0xc6 of the hero file and part of
|
|
save games, both through the JSON inventories already (diagnostic log).
|
|
- Items in hero files (`ItemDataMgr::saveHero` `0x6046f0`, chunk 0xc2): the
|
|
ids of both inventories, equipment, weapon sets; per item its type (+0x10)
|
|
and the object's serializer `vf1c(stream, 1, 0)` (ret 0xc).
|
|
- Loading (`loadHero` `0x605900`, chunk 0xc2): `cObjectManager::Create(type,
|
|
0, 0, 0)` `0x5fb590`, `vf1c(stream, 0, version)` (version = header byte,
|
|
0x1b), then the saved id (read into +0xc) is replaced by the new one
|
|
(`ReplaceItemId`), flags +0x14: clear 0x200000, 0x30 if bit 2, 0x10; +0x39
|
|
= owner hero id.
|
|
- `cEngine::~cEngine` `0x60d5e0` (plain ret) runs before the object manager is
|
|
destroyed: `game::OnGameEnd`.
|
|
|
|
## Mod (`src/mods/sharedchest.cpp`)
|
|
|
|
- An inventory of our own (`cInventoryEntry::Construct` `0x5d7a10`, owner
|
|
0x11 so it counts as a player inventory).
|
|
- Tabs: a `cUI_TabSheet` (constructor `0x728ed0`, `AddTab` `0x7290d0`) built
|
|
right after the chest window (`cUI_Chest::cUI_Chest` `0x6ac7f0`), the same
|
|
control as the inventory's Rucksack / Kampfkünste / Combos headers, so the
|
|
selected / hover look is the game's. Its layout (`0x729210`, headers in a row
|
|
above the sheet) is followed by ours: a column left of the grid's top-left
|
|
corner. Labels "Truhe" / "Gemeinsam" through `game::RegisterText`
|
|
(`src/game/ui/texts.cpp`, an override of `GetText` `0x672f70`). Switching
|
|
(`cUI_TabControl::SetActive` `0x728af0`) sets window +0x158 to inventory
|
|
0x11 or the shared one (origin and size copied from the chest). Pages are
|
|
empty controls.
|
|
- The tab sheet is added to the window's control list (`cUI_Window2::AddControl`
|
|
`0x727120`); only those controls are drawn and get events (a parent alone
|
|
isn't enough).
|
|
- Grid place: the constructor sets inventory 0x11 to (window x, 20), 20 x 10
|
|
once, but loads overwrite it (the game's inventory read `0x5df09b` resets
|
|
some inventories to 0/0; the JSON inventories restore the saved place), so
|
|
the chest drew at the wrong spot after some loads. Both tabs' grids are put
|
|
back to the constructor's values every tick and on each tab switch.
|
|
- `MoveItem` from/to 0x11 while the shared tab is open moves from/to it.
|
|
- File: `{"format": "sacred_re.shared_chest", "version": 1, "items": [{cell,
|
|
w, h, type, data (hex of vf1c), count}]}`; written after each successful
|
|
`saveHero` and after each save-game write (in-game saves don't call saveHero;
|
|
via a temp file), read on the first engine tick with a hero after a session
|
|
start (`game::OnGameStart`, cEngine::cEngine `0x60ac70`) or a save-game read
|
|
with a hero; the grid is cleared when the session ends.
|
|
|
|
## Open / to check
|
|
|
|
- Whether save games (PAK) also store the shared chest's item objects (they
|
|
live in the object manager outside the 32 inventories).
|
|
- loadHero's extra fix-up for some item classes (`0x5beaa0` / `0x5d3a20`,
|
|
item classes 5, 6, 8, 0xd, 0x11..0x19, 0x1b, 0x1d) is not repeated.
|
|
- Multiplayer: not supported.
