Teleportationstrank

Request (2026-10-17): the yellow potion becomes "Teleportationstrank"; drinking it opens the window of known portals and the hero can teleport to one of them.

Measured

  • The yellow potions come in stages (small / medium / large; seen types 0x1434 and 0x141a), all potion kind 5 (logged in cCreature::UseItem 0x54a8f0).
  • Touching a teleporter logs cInterpretSQW::Teleporter(hex=N) (0x4ae330): it sets bit N in the hero's known portals (hero +0x578) and posts a UI event (constructor 0x553080) of type 0x39 to DEFAULT_BUSYDLG with +8 = 2, +0xc = 5 (mode: portals; 6 for underworld portals above 0xd) and +0x10 = the mask. cUI_BusyDlg::HandleEvent (0x720c10) calls SetMode (0x720180).
  • Choosing a portal: the engine's portal case (0x619671, log EE_USEPORTAL) teleports the hero with cCreature::Teleport (0x54d840), returning to 0x6197c8.

Mod (src/mods/teleportpotion.cpp)

  • Every item type of potion kind 5 counts. Their name, "Trank der Konzentration", is replaced in every game text from the DLL's start (game::ReplaceInTexts, applied where the game fetches a text): the item names (stage words in front stay) and the bottom bar's quick-select tooltip ("Trank der Konzentration [R]", its own text id). Before (until 2026-10-19) the names were collected from the item types at game start, so the main menu (options' key bindings) still had the old name.
  • cCreature::UseItem (hooked in itemstack.cpp) asks teleportpotion::UseItem first: for the hero's Teleportationstrank it posts the teleporter's event with the hero's mask instead of the drink.
  • The potion is used up (flag, RemoveItem, DestroyObject as UseItem does; a stack loses one) only when cCreature::Teleport is called from the portal case while it is pending; closing the window keeps it.

Campaign (2026-10-21)

The potion showed Ancaria's portals in the Underworld. cInterpretSQW::Teleporter (0x4ae330) chooses the busy dialog's mode by the portal touched: index > 0xd (Underworld) mode 6, else mode 5, both with the hero's known-portal mask (+0x578). The potion now chooses by the running campaign, g_campaign (0x182cdc8, u16: 0 Ancaria, 1 Underworld): mode 6 in the Underworld.
