ABOUT

pybot-dhewm3 is a fork of the dhewm3 project. It is experimental code to demonstrate and develop python bots within doom3. The python bots are forked (potentially running on a different processor) and they communicate via simple remote procedure calls. The project allows experimentation to occur with different API calls.

pybot-dhewm3 bots are expected to be existing in maps generated by chisel (https://github.com/gaiusm/chisel). These maps resemble those found in the Temple of Apshai and Morloc Tower from the 1980's.

The original README.md continues here:

dhewm 3 is a Doom 3 GPL source port, know to work on at least Windows, Linux, Mac OS X and FreeBSD.

The goal of dhewm 3 is bring DOOM 3 with the help of SDL to all suitable platforms.

Bugs present in the original DOOM 3 will be fixed (when identified) without altering the original gameplay.

CHANGES

Compared to the original DOOM 3, the changes of dhewm 3 worth mentioning are:

64bit port
SDL for low level OS support, OpenGL and input handling
OpenAL for audio output, all OS specific audio backends are gone
OpenAL EFX for EAX reverb effects (read: EAX-like sound effects on all platforms/hardware)
Better support for widescreen (and arbitrary display resolutions)
A portable build system based on CMake
(Cross-)compilation with mingw-w64

GENERAL NOTES

Game data and patching

This source release does not contain any game data, the game data is still covered by the original EULA and must be obeyed as usual.

You must patch the game to the latest version (1.3.1). See the FAQ for details, including how to get the game data from Steam on Linux or OSX.

Note that Doom 3 and Doom 3: Resurrection of Evil are available from the Steam store at

http://store.steampowered.com/app/9050/

http://store.steampowered.com/app/9070/

You can also buy Steam keys at the Humble Store; currently this seems the only way to buy a Doom3 Steam key in Germany (Note that Germans still can't buy the RoE Addon there):

Compiling

The build system is based on CMake: http://cmake.org/

Required libraries are not part of the tree. These are:

zlib
libjpeg (v8)
libogg
libvorbis
libvorbisfile (may be part of libvorbis)
OpenAL (OpenAL Soft required, Creative's and Apple's versions are made of fail)
SDL v1.2 or 2.0 (2.0 recommended)
libcurl (optional, required for server downloads)

For UNIX-like systems these libraries need to be installed (including the developer files). It is recommended to use the software management tools of your OS (apt-get, portage, rpm, BSD ports, Homebrew for OS X, ...).

For Windows there are two options:

Use the provided binaries (recommended, see below)
Compile these libraries yourself

Create a distinct build folder outside of this source repository and issue the cmake command there, pointing it at the neo/ folder from this repository:

cmake /path/to/repository/neo

OSX users need to point cmake at OpenAL Soft (better solutions welcome):

cmake -DOPENAL_LIBRARY=/usr/local/opt/openal-soft/lib/libopenal.dylib -DOPENAL_INCLUDE_DIR=/usr/local/opt/openal-soft/include /path/to/repository/neo

Using the provided Windows binaries

Get a clone of the latest binaries here: https://github.com/dhewm/dhewm3-libs

There are two subfolders:

32bit binaries are located in "i686-w64-mingw32"
64bit binaries are located in "x86_64-w64-mingw32"

Issue the appropriate command from the build folder, for example:

cmake -G "Visual Studio 10" -DDHEWM3LIBS=/path/to/dhewm3-libs/i686-w64-mingw32 /path/to/repository/neo

cmake -G "MinGW Makefiles" -DDHEWM3LIBS=/path/to/dhewm3-libs/x86_64-w64-mingw32 /path/to/repository/neo

The binaries are compatible with mingw-w64 and all MSVC versions.

Cross compiling

For cross compiling a CMake Toolchain file is required.

For the mingw-w64 toolchain "i686-w64-mingw32" on Ubuntu precise it looks like:

set(CMAKE_SYSTEM_NAME Windows)
set(CMAKE_SYSTEM_PROCESSOR i686)

set(CMAKE_C_COMPILER i686-w64-mingw32-gcc)
set(CMAKE_CXX_COMPILER i686-w64-mingw32-g++)
set(CMAKE_RC_COMPILER i686-w64-mingw32-windres)

set(CMAKE_FIND_ROOT_PATH /usr/i686-w64-mingw32)

set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)

Then point CMake at your Toolchain file: cmake -DCMAKE_TOOLCHAIN_FILE=/path/to/Toolchain.cmake -DDHEWM3LIBS=/path/to/dhewm3-libs/i686-w64-mingw32 /path/to/repository/neo

Back End Rendering of Stencil Shadows

The Doom 3 GPL source code release does not include functionality enabling rendering of stencil shadows via the "depth fail" method, a functionality commonly known as "Carmack's Reverse".

Note that this does not change the visual appereance of the game. The shadows look the same, they're just created in a slightly different way. In theory there might be a small performance impact, but on hardware less than ten years old it shouldn't make a difference.
