Vampire Crawlers Deck Tracker

Read-only second-screen deck tracker for Vampire Crawlers.

Desktop App

Development launch:

npm install
npm run desktop

Build a Windows installer:

npm run build:win

The desktop app auto-detects the default Steam install and save file, starts the local tracker server internally, and opens the UI in an app window.

Generated art and card-cost data are stored in the user's app data folder:

%APPDATA%\VampireCrawlersDeckTracker\generated

The app should not ship extracted Vampire Crawlers PNGs. Each user rebuilds local art from their own installed copy. A small fallback card-cost map ships with the app and can be regenerated from the installed game.

Current art-cache rebuild requirement:

python -m pip install UnityPy pillow

For distributable builds, bundle the extraction helper first so non-technical users do not need Python installed:

python -m pip install pyinstaller UnityPy fmod_toolkit archspec pillow
npm run build-asset-builder
npm run build:win

Browser Prototype

The current prototype reads the active save file from:

%USERPROFILE%\AppData\LocalLow\Nosebleed Interactive\Vampire Crawlers\Save\SaveProfile0.save

It watches the serialized card piles already written by the game:

• HandPile
• DrawPile
• DiscardPile
• ComboPile
• any other cardPileId blocks found in the save

Run

npm start

Then open:

http://127.0.0.1:5177

Open the extracted art browser:

http://127.0.0.1:5177/art.html

Extract Art

python tools\extract_art.py --min-size 16
python tools\build_card_map.py
python tools\build_card_cost_map.py

The extractor writes PNG sprites to public/assets/art and metadata to public/assets/art-manifest.json. The mapper reads Unity CardConfig and CardGroup objects and writes public/assets/card-map.json. The cost mapper reads Unity CardConfig mana fields and writes public/assets/card-costs.json.

Manual overrides can still be added to public/assets/card-map.json:

{
  "Card_A_1_MagicWand": "assets/art/WandHoly_e2f29fa6df.png"
}

A first large-sprite contact sheet is available at:

Notes

This first pass does not edit saves, patch game files, inject code, or read process memory. It polls /api/deck every two seconds and refreshes the browser UI.

If the save only updates at room boundaries or after major events, the next step is a BepInEx IL2CPP plugin that hooks the game-side card pile model and exports a small local JSON file or localhost API for this same dashboard.
