#ViZDoom http://vizdoom.cs.put.edu.pl

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.

• API for C++, Python and Java,
• Easy-to-create custom scenarios (examples available),
• Single-player (sync and async) and multi-player (async) modes,
• Fast (up to 7000 fps in sync mode, single threaded),
• Customizable resolution and rendering parameters,
• Access to the depth buffer (3D vision)
• Off-screen rendering,
• Lightweight (few MBs),
• Multi-platform

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

• Lua bindings,
• Multi-player working in sync mode,
• Labeling game objects visible in the frame,
• Time scaling in async mode.

###Linux

####Dependencies

• CMake 3.0+
• Make
• GCC 4.6+
• Boost libraries
• Python 2.7+ with Numpy and Boost.Python for Python binding (optional)
• JDK for Java binding (JAVA_HOME must be set) (optional)

Additionally, ZDoom dependencies are needed.

####Compiling In ViZDoom's root directory:

cmake -DCMAKE_BUILD_TYPE=Release -DBUILD_PYTHON=ON -DBUILD_JAVA=ON
make

-DBUILD_PYTHON=ON and -DBUILD_JAVA=ON CMake options for Python and Java bindings are optional (default OFF).

###Windows

We are providing compiled runtime binaries and development libraries for Windows here.

####Dependencies

• CMake 3.0+
• Visual Studio 2012+
• Boost libraries
• Python 2.7+ with Numpy and Boost.Python for Python binding (optional)
• JDK for Java binding (JAVA_HOME must be set) (optional)

Additionally, ZDoom dependencies are needed.

####Compiling Run CMake GUI, select ViZDoom's root directory and set paths to:

• BOOST_ROOT
• BOOST_INCLUDEDIR
• BOOST_LIBRARYDIR
• PYTHON_INCLUDE_DIR (optional)
• PYTHON_LIBRARY (optional)
• NUMPY_INCLUDES (optional)
• ZDoom dependencies paths

In configuration select BUILD_PYTHON and BUILD_JAVA options for Python and Java bindings (optional, default OFF).

Use generated Visual Studio solution to build all ViZDoom's parts.

###OSX Untested, code is compatible, CMake still may need minor adjustments. Let us know if You are using ViZDoom on OSX.

####Dependencies

• CMake 3.0+
• XCode 5+
• Boost libraries
• Python 2.7+ with Numpy and Boost.Python for Python binding (optional)
• JDK for Java binding (JAVA_HOME must be set) (optional)

Additionally, ZDoom dependencies are needed.

####Compiling Run CMake and use generated project.

Users with brew-installed Python may need to manually set: -DPYTHON_INCLUDE_DIR=/usr/local/Cellar/python/2.x.x/Frameworks/Python.framework/Versions/2.7/include/python2.7 and -DPYTHON_LIBRARY=/usr/local/Cellar/python/2.x.x/Frameworks/Python.framework/Versions/2.7/lib/libpython2.7.dylib

####Configuration Craeting symlink to the app executable may be need: rm bin/vizdoom && ln -s vizdoom.app/Contents/MacOS/vizdoom bin/vizdoom

###Compilation output Compilation output will be placed in vizdoom_root_dir/bin and it should contain following files (Windows names are in brackets):

• bin/vizdoom (vizdoom.exe) - ViZDoom executable
• bin/vizdoom.pk3 - resources file used by ViZDoom (needed by ViZDoom executable)
• bin/libvizdoom.a (vizdoom.lib) - C++ ViZDoom static library
• bin/libvizdoom.so (vizdoom.dll) - C++ ViZDoom dynamically linked library
• bin/python/vizdoom.so (vizdoom.pyd) - ViZDoom Python module
• bin/java/libvizdoom.so (vizdoom.dll) - ViZDoom library for Java
• bin/java/vizdoom.jar - Contains ViZDoom Java classes

• Dockerfile
• Docker image

Note: third-party maintained

##Examples

Before running the provided examples, make sure that freedoom2.wad is placed it in the scenarios subdirectory (on Linux it should be done automatically by the building process).

• Python
• C++
• Java
