A CMake-based fork of the GPLv3-licensed CyanWorlds.com Engine (Headspin/Plasma), with a focus on bug-fixes, cross-platform compatibility, and enhanced features.

- dirtsand - An open-source Plasma-compatible server project.
- moul-assets - MOUL game assets repository.
Plasma currently requires the following third-party libraries:
- NVIDIA PhysX 4.1 - https://github.com/NVIDIAGameWorks/PhysX
- Python 3.8 (or higher) - https://www.python.org/downloads/
- libOgg and libVorbis - http://www.xiph.org/downloads/
- OpenSSL - http://www.slproweb.com/products/Win32OpenSSL.html
- OpenAL Soft - https://openal-soft.org/
- eXpat - http://expat.sourceforge.net/
- libJPEG - http://libjpeg-turbo.virtualgl.org/
- libPNG - http://www.libpng.org/
- zlib - http://zlib.net/
- libcurl - http://curl.haxx.se/
- string_theory - http://github.com/zrax/string_theory/
- Standalone ASIO - https://think-async.com/Asio/
The following libraries are optional:
- (for building resource.dat) CairoSVG - https://cairosvg.org/
- (for building resource.dat) Pillow - https://python-pillow.org/
- (for plFontConverter) Freetype - http://freetype.org/
- (for the GUI tools) Qt5 - http://www.qt.io/download-open-source/
- (for video) VPX - http://www.webmproject.org/
- (for video and voice chat) Opus - http://www.opus-codec.org/
- (for legacy voice chat) speex - http://www.speex.org/downloads/
All required libraries are available as vcpkg ports or can be built using their individual build instructions.
Currently, compilation only targets Windows systems and requires Visual Studio 2019 (including Visual Studio 2019 Community).
- Clone the repository, including all submodules, in a git client or by
executing the following at the command line:
git clone --recurse-submodules https://github.com/H-uru/Plasma.git - Open Microsoft Visual Studio 2019.
- Select Open a local folder and choose the folder where you cloned the repository.
- Open the CMake Settings by chosing Project > CMake Settings for Plasma from the Visual Studio menu bar.
- Add a new configuration in CMakeSettings.json by clicking the green + button.
- Select x86-Release in the window that pops up.
- Compile the client by using Build > Install Plasma from the Visual Studio menu bar.
- The client will be built and installed into the
out\install\x86-Releasesubfolder of where you cloned the repository. This will be referred to as the MOUL-OS folder.
To run the Internal Client for testing with MOULa content, you will need the a fully-patched installation of MOULa provided by Cyan Worlds.
- Copy the folders avi, dat, and sfx from your existing MOULa installation to the MOUL-OS folder.
- Copy the example_server.ini file from the root of the Plasma repository into your MOUL-OS folder, and rename it as server.ini. If you are running your own dirtsand server or are connecting to one run by someone else, use the server.ini generated from that.
- Create a shortcut in the MOUL-OS folder to the compiled plClient.exe.
- Edit the shortcut's properties, and after the final quotation mark in the
Target field, add
/LocalData. Also, change the Start in field to the path of your MOUL-OS folder. - Double-click the shortcut to connect to your server and test!
Alternatively, if you wish to be able to debug using a single content folder from inside Visual Studio:
- Open the Plasma folder in Visual Studio.
- Switch to CMake Targets View in the Solution Explorer.
- Right-click on the plClient (executable) target in the Solution Explorer.
- Select Debug and Launch Settings > plClient.exe (Install).
- Add the following to the configurations:
"args": "/LocalData"

- This code was forked from the initial release repository at OpenUru.org.
This software uses some non-free libraries for which exceptions appear in the source code license inserts. It is suggested that anyone who thinks of doing substantial further work on this program should first free it from dependence on the non-free libraries so that it does the same job without the non-free libraries. Further introduction of non-free libraries likely would require a revised license and thus permission from all contributors to the codebase. That being problematic, any additional non-free libraries are unlikely to be accepted by Cyan Worlds or the development community.
