callsign-polytech mod wiki

Game: S.T.A.L.K.E.R.: Call of Pripyat (Steam, patch 1.6.02) Engine: OpenXRay (built from source) Platform: Linux (Debian)

This wiki documents everything the team has verified in-game while building the mod. It is not a general CoP modding reference — every page covers only what we actually tested, with notes on what remains unverified. When something is marked [UNVERIFIED], do not rely on it without testing first.

Environment & Tools

Building OpenXRay, unpacking game archives, directory layout, and the gamedata/ override system. Start here if you're setting up a new machine.

NPC & Quests Cretion

Full pipeline for creating custom NPCs and quests: NPC registration, logic files, Lua spawning, dialog structure (start_dialog vs actor_dialog), task_manager quests (single- and two-stage), map markers, quest fail conditions, and all the pitfalls we hit along the way.

Communication Text (Dialogs & Strings)

How CoP's three-layer text system works: character_desc → dialogs → string_table. Phrase branching, conditions, dialog XML structure, and string table files.

Visual Files (Textures, UI, Inscriptions)

Working with DDS textures, UI atlases, and in-world inscriptions.
