## OpenGothic
Open source re-implementation of Gothic 2: Night of the Raven.
Motivation: The original Gothic 1 and Gothic 2 are still great games, but it's not easy to make them work on modern systems.
The goal of this project is to make a feature complete Gothic game client compatible with the original game data and mods.

#### Work in progress
[](https://ci.appveyor.com/project/Try/opengothic)
Development is focused on Gothic 2 and new features are not tested for Gothic 1 compatibility. While Gothic 1 is not officially supported pull requests that fix Gothic 1 — and general — bugs are welcome.
The original game has been replicated fully; you can complete both the main quest and the addon. Check out the [bugtracker](https://github.com/Try/OpenGothic/issues) for a list of known issues.
OpenGothic is designed to utilize features of modern graphic hardware and api's like mesh shaders or ray tracing. While mesh-shader not mandatory, yet don't expect OpenGothic to run well on low-end or outdated graphic cards.
#### Prerequisites
Gothic 2: Night of the Raven is required as OpenGothic does not provide any built-in game assets or scripts.
Supported systems are:
* Windows (DX12, Vulkan)
* Linux (Vulkan)
* MacOS (Metal)
## How to play
### Windows
1. If not already done install Gothic. OpenGothic comes with auto-path detection if your Gothic files are in a common path.
* "C:\Program Files (x86)\JoWooD\Gothic II"
* "C:\Gothic II"
* "C:\Program Files (x86)\Steam\steamapps\common\Gothic II"
2. Download OpenGothic and extract into a folder of your choice. Available options are:
* A [Pre-Release](https://github.com/Try/opengothic/releases/latest) (recommended)
* Alternatively a recent test build from [CI](https://ci.appveyor.com/project/Try/opengothic/history)
3. Run `Gothic2Notr.exe`.
If nothing happens check `log.txt` and look for the line `invalid gothic path`. In this case OpenGothic fails to find your Gothic installation and you have to explicitly specify its location via `-g` paramter. Either you create a shortcut to `Gothic2Notr.exe` and change the target line in Properties to e.g.
`Gothic2Notr.exe -g "C:\Program Files (x86)\Steam\steamapps\common\Gothic II"`
or you can edit `Gothic2Notr.bat` and run this file instead.
### Linux
1. If not already done install Gothic via Wine/Proton or copy the game files from a Windows installation.
2. You can download a build from [CI](https://ci.appveyor.com/project/Try/opengothic/history) and extract into a folder of your choice. Alternatively OpenGothic can be built manually. For Arch the [AUR](https://aur.archlinux.org/packages/opengothic) provides a 3rd party package.
3. Run `Gothic2Notr.sh -g "~/PlayOnLinux's virtual drives/Gothic2_gog/drive_c/Gothic II"` (example path, use path to your Gothic installation instead)
You can edit `Gothic2Notr.sh` and change the line `exec "$DIR/Gothic2Notr" "$@"` to
`exec "$DIR/Gothic2Notr" "$@" -g "~/PlayOnLinux's virtual drives/Gothic2_gog/drive_c/Gothic II"`
to not have to enter path manually every time. Then run `Gothic2Notr.sh` without arguments to start.
### MacOS
1. If not already done install Gothic. Instructions how to obtain the game files can be found [here](https://macsourceports.com/faq#getgamedata). OpenGothic comes with auto-path detection if your Gothic files are in `"~/Library/Application Support/OpenGothic"`.
2. Download a build from [Mac Source Ports](https://macsourceports.com/game/gothic2) and follow the installation instructions given there.
Alternatively recent test builds are available from [CI](https://ci.appveyor.com/project/Try/opengothic/history) that can be extracted into a folder of your choice. You can compile a fresh build as well.
3. Run `Gothic2Notr.sh`
If OpenGothic fails to find your Gothic files you have to explicitly specify its location via `-g` parameter.
Change the line `exec "$DIR/Gothic2Notr" "$@"` to reflect your Gothic path e.g.
`exec "$DIR/Gothic2Notr" "$@" -g "~/PlayOnLinux's virtual drives/Gothic2_gog/drive_c/Gothic II"`
---
### Modifications
Mods can be installed as usual. Provide the `modfile.ini` to OpenGothic via `-game:` parameter to play. Example:
`Gothic2Notr.exe -game:Karibik.ini`
#### What's working?
Content mods (retexture/reworld/animations) that only rely on regular scripting and do not use memory hacking.
#### What's not?
- Ikarus/LeGo
There are ongoing efforts to support parts of it to make at least some popular mods like `Chronicles of Myrtana` playable. Progress can be tracked in the corresponding [issue](https://github.com/Try/OpenGothic/issues/231). An explanantion how Ikarus works is given [here](https://github.com/Try/OpenGothic/discussions/396#discussioncomment-4823499).
- Union (32 bit and Windows only, [not possible](https://github.com/Try/OpenGothic/issues/195))
- DX11 Renderer - same as Union, but don't worry - OpenGothic has nice graphics out of the box
- AST sdk
- Ninja
## Build Instructions
### Linux
Install dependencies:
* Ubuntu 20.04/22.04 and their derived distros
```bash
source <(cat /etc/os-release | grep UBUNTU_CODENAME)
# latest Vulkan SDK provided externally as Ubuntu packages are usually older
wget -qO - http://packages.lunarg.com/lunarg-signing-key-pub.asc | sudo apt-key add -
sudo wget -qO /etc/apt/sources.list.d/lunarg-vulkan-${UBUNTU_CODENAME}.list http://packages.lunarg.com/vulkan/lunarg-vulkan-${UBUNTU_CODENAME}.list
sudo apt update
sudo apt install vulkan-sdk
# distro-provided packages
sudo apt install git cmake g++ glslang-tools libvulkan-dev libasound2-dev libx11-dev libxcursor-dev
```
* Arch
```bash
sudo pacman -S git cmake gcc glslang vulkan-devel alsa-lib libx11 libxcursor vulkan-icd-loader libglvnd
```
* Fedora
```bash
sudo dnf install git cmake gcc-c++ glslang vulkan-loader-devel alsa-lib-devel libX11-devel libXcursor-devel vulkan-validation-layers-devel libglvnd-devel
```
#### Compilation
```bash
# 1st time build:
git clone --recurse-submodules https://github.com/Try/OpenGothic.git
cd OpenGothic
cmake -B build -DBUILD_SHARED_LIBS=ON -DCMAKE_BUILD_TYPE:STRING=RelWithDebInfo
make -C build -j $(nproc)
# following builds:
git pull --recurse-submodules
make -C build -j $(nproc)
```
Executables can be located at `OpenGothic/build/opengothic`.
### MacOS
```bash
brew install glslang
git clone --recurse-submodules https://github.com/Try/OpenGothic.git
cd OpenGothic
cmake -H. -Bbuild -DCMAKE_BUILD_TYPE:STRING=RelWithDebInfo
cmake --build ./build --target Gothic2Notr
```
Executables can be located at `OpenGothic/build/opengothic`.
## Video

## Available Graphic options
Game menu in gothic is done by scripting. While orignal graphics settings do not apply to current-gen graphics, engine redefines meaning for some of tweakables:
* `Settings` -> `Extended configuration`
* `Cloud Shadows` mapped to SSAO.
* `Radial Fog` mapped to "Volumetric fog"
* `Reflections` reused, for screen space reflections
* `Settings` -> `Video settings`
* Internal rendering resolution, for 3D, can be altered here. UI and text is always rendered at full resolution.
* Application command line:
* Ray tracing: setting affects only capable hardware, off by default for igpu's, add `-rt 1` to enable
Rendering distance is not customizable.
