OpenSource-Reimplementation of the zEngine, used by the game "Gothic" and "Gothic II".

Attention!

The project has been restarted. Here is the new repository: https://github.com/REGoth-project/REGoth-bs

Don't forget to check out the REGoth-Wiki for more information about the project!

A list showing the current state of the engine, can be found here.

Source

Make sure to clone this repository with the --recursive flag:

ssh:
git clone --recursive git@github.com:degenerated1123/REGoth.git
https:
git clone --recursive https://github.com/degenerated1123/REGoth.git

To update the repo, you need to make sure to update the submodules as well. Instead of simply pulling the repository, you can do:

git pull --recurse-submodules

Building

Note: If you are missing packages or are having trouble building on your platform, you can check out this wiki-page, which may contain more detailed instructions. If you don't find your platform there, I'd kindly ask you to add some instructions for other people to that wiki-page!

You will need CMake (3.1 or newer) and a C++14-capable compiler. Currently supported/tested are:

You will also need a copy of libsndfile installed on your computer.

Obtaining libsndfile and libxinerama

*nix systems (Linux, BSD, macOS)

On most *nix systems, this can be obtained using a package manager, for example on Debian/Ubuntu:

$ sudo apt install libsndfile1-dev libasound2-dev
$ sudo apt install libxinerama-dev

Or on macOS

$ brew install libsndfile # Needs Homebrew

Windows

libsndfile will need to be compiled separately. Create a directory somewhere on your system to store the compiled files, then run

mkdir build-libsndfile
cd build-libsndfile
cmake -D CMAKE_INSTALL_PREFIX=compiled/files/folder path/to/REGoth/lib/libdmusic/utils/dls2sf/lib/libsndfile
cmake --build . --target install --config Release

Compiling REGoth

Then:

cd path/to/REGoth
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release .. # On *nix systems this is sufficient
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_PREFIX_PATH=compiled/files/folder .. # On Windows

If CMake complains about some folders missing a CMakeLists.txt, you most likely forgot to clone with the --recursive-flag! Simple do git submodule update --init --recursive and it should work.

Then, choose depending on your OS:

Linux, MacOS and other *nix

make -j4

Windows

Starting Visual Studio 2017 you can use the integrated cmake functionality to open the cloned folder.
Check out the how to build wiki page for details on this.

For previous versions of Visual Studio, open the generated REGoth.sln and build as usual.
Alternatively, you may run this command inside of the build folder:

cmake --build . --config release

Running

The compiled files are inside the build/bin directory.

Make sure to copy the content/shaders folder to the working directory of the compiled REGoth-Executable. Then, run the program with the following flags:

REGoth -g "path/to/gothic1or2" -w startworld.zen

Where path/to/gothic1or2 points to the root of a Gothic I or II installation and startworld.zen is one of the Zen-Files found in a .vdf-files in the games data/-directory. For example: newworld.zen or addonworld.zen for Gothic II.

It is recommended to run this from the commandline, to see the debug-output of the program.

Additionally, for a list of possible commands, run REGoth --help.

Development

If you want to help out and don't know where to start, I suggest reading the wiki-page, which contains information about the engine-layout and lists of which features are missing (Not yet, though!).
