ViZDoom Build Status

ViZDoom allows developing AI bots that play Doom using only the visual information (the screen buffer). It is primarily intended for research in machine visual learning, and deep reinforcement learning, in particular.

ViZDoom is based on ZDoom to provide the game mechanics.



  • Multi-platform,
  • API for Python, C++, Lua, Java and Julia (thanks to Jun Tian),
  • Easy-to-create custom scenarios (visual editors, scripting language and examples available),
  • Async and sync single-player and multi-player modes,
  • Fast (up to 7000 fps in sync mode, single threaded),
  • Lightweight (few MBs),
  • Customizable resolution and rendering parameters,
  • Access to the depth buffer (3D vision),
  • Automatic labeling game objects visible in the frame,
  • Off-screen rendering,
  • Episodes recording,
  • Time scaling in async mode.

ViZDoom API is reinforcement learning friendly (suitable also for learning from demonstration, apprenticeship learning or apprenticeship via inverse reinforcement learning, etc.).

Installation/Building instructions

Windows build

For Windows we are providing compiled runtime binaries and development libraries:

1.1.8pre (2019-08-28):

See Installation of Windows binaries


Before running the provided examples, make sure that freedoom2.wad is placed in the same directory as the ViZDoom executable (on Linux and macOS it should be done automatically by the building process):

  • Python (contain learning examples implemented in PyTorch, TensorFlow and Theano)
  • C++
  • Lua (contain learning example implemented in Torch)
  • Java
  • Julia

Python examples are currently the richest, so we recommend to look at them, even if you plan to use other language. API is almost identical for all languages.

See also the tutorial.

Also full documentation of engine and ACS scripting language can be found on ZDoom Wiki.

Useful parts:

Awesome Doom tools

  • SLADE3 - great Doom map (scenario) editor for Linux, MacOS and Windows.
  • Doom Builder 2 - another great Doom map editor for Windows.
  • OBLIGE - Doom random map generator and PyOblige is a simple Python wrapper for it.
  • Omgifol - nice Python library for manipulating Doom maps.
  • NavDoom - Maze navigation generator for ViZDoom (similar to DeepMind Lab).
  • MazeExplorer - More sophisticated maze navigation generator for ViZDoom.
  • ViZDoomGym OpenAI Gym Wrapper for ViZDoom.


This project is maintained and developed in our free time. All bug fixes, new examples, scenarios and other contributions are welcome! We are also open to features ideas and design suggestions.
