Setting up a Development Environment

First you’re gonna need some software:

  • Git or one of the many third-party UIs that make it easier to use. Make sure to let it install to your PATH like this.
  • Python 3.7 or higher. Make sure to install it into your PATH on Windows. You should get python from Versions installed from the windows store sometimes cause build issues.
  • .NET 7.0 SDK. Visual Studio also installs this if you’re on Windows.
    • ARM (M1) Mac users: You need to make sure to install x64 .NET, not ARM .NET. The engine does not currently run natively on Mac ARM so using x64 via Rosetta 2 emulation is recommended.
  • Preferably an IDE to make development not painful (all free options unless otherwise noted):
    • For Windows, Visual Studio 2022 Community. For a minimal install (Jesus it’s large) you’re gonna want the .NET desktop development workload, the C# compiler, C# support, NuGet package manager, MSBuild and .NET 7 SDK or something along those lines.
    • For macOS, Visual Studio for Mac.
    • For all platforms, (NOT FREE) Rider is one of the best IDEs available, and many SS14 devs prefer it over Visual Studio. College/University students can get a free education license, even if they’re not a computer science major.
    • For all platforms, Visual Studio Code with the C# extension. Usually an inferior IDE experience than full blown IDEs like regular Visual Studio, but some experienced programmers enjoy the minimalism.
    • For all platforms, VSCodium with the C# extension. Open source and without the bloat and tracking of VSCode.

1. Cloning

Even if you already know Git, scroll down to read the section about submodule setup. Seriously.

If you’re familiar with Git, just fork and clone the repository, set up remotes, and then follow the submodule guide below.

If you’re unfamiliar with Git, or just don’t know how to proceed, follow the Git for the SS14 Developer guide, which goes in depth on how to contribute to the game and how to set up your initial repository. It also touches on submodule setup, but that’s included here as well because of its importance.

2. Submodule Setup

We have an automatic submodule updater so you don’t have to worry about running git submodule update --init --recursive all the time.

Run inside the repo you downloaded with Python. Preferably from a terminal too. This should take a few seconds so if it instantly stops then check if you are running Python 3.7+ otherwise keep reading.

If running immediately opens and closes a window: do not worry. This does not mean that it failed. The script closes automatically upon completion, so if you want to verify that it worked properly, check the submodule /RobustToolbox/ and verify that all the files are there. If not try checking out the troubleshooting at the bottom of this page.

Note: If you have any issues when getting started with missing files it’s recommended you run git submodule update --init --recursive by hand once in case something went wrong with python.

If you do want to modify the engine directly however, or you want to update the submodule manually (the auto updating can be a pain), make a file called DISABLE_SUBMODULE_AUTOUPDATE inside the BuildChecker/ directory.

And with that, your repo is now properly setup!

3. Setup an IDE

Visual Studio

  1. Download Visual Studio Community (if you don’t own a paid version) from here
  2. Run the installer and choose .net desktop development, then install
  3. If the installer asks you for a development environment select Visual C#.
  4. Open Visual Studio
  5. Select Open a project or solution, then navigate to your cloned repository from above and open SpaceStation14.sln

Jetbrains Rider

  • TODO


  1. Download VSCodium Here or more directly on Github Here (On the latest release, click the assets dropdown then scroll to the ZIP or .exe for your OS).
  2. Run the installer or extract the zip file to a location of your choice and run the .exe once extracted.
  3. Once installed, navigate to the Extensions tab (part way down on the top left corner bar, looks like 4 tiles) and search for “C#”. An extension by “Muhammad-Sammy” with over 70K downloads and a green / white logo is the one, install that. Extension ID muhammad-sammy.csharp.
  4. Select File > Open Folder, then navigate to your cloned repository from above and open this full folder.
  5. Now you can run and debug your game. Select the icon above “Extensions” from earlier for “Run and Debug” and from the dropdown next to the green play button you can select “Server/Client”. This will run both the client and server, opening the game for you to debug. Relevant information will pop up in the debug along the bottom. Select the processes in the call stack on the left to change what you are debugging.

4. Starting SS14

Now you can get on to compiling the client and server! Use your flavor of IDE to open the solution file SpaceStation14.sln and press the build button.

To compile without an IDE, run dotnet build in the Space Station 14 repo directory. Then, call the following commands to run the client and server.

  • dotnet run --project Content.Server
  • dotnet run --project Content.Client

Both these commands use a debug configuration by default. To enable release optimizations, add --configuration Release to the dotnet invocation.

Note: If you’re having problems with dotnet not finding libssl (e.g. when using libressl), try setting the CLR_OPENSSL_VERSION_OVERRIDE environment variable to the appropriate version. For instance, set it to 48 if your /usr/lib contains If that doesn’t work you can also try running ln -s /usr/lib/ /usr/local/lib/ instead.

5. Configuring Build Options

The SS14 client and server are independent projects, but both can launch with a single button somewhere in your IDE. This needs to be set up, however. Note: It is recommended that you run Content.Client and Content.Server when developing from your IDE. Not Robust.Client or Robust.Server. The reason is that running Content.* will make your IDE aware of dependencies correctly and ensure everything is rebuilt nicely. If you run Robust.Client directly you have to make sure the solution is fully built every time which is annoying and easy to forget. If you’re unsure what Robust or Content are, check out this page on how the project is organized.

Visual Studio 2022

In Visual Studio 2022, you can configure the build button to run both the server and client by right clicking the solution, then selecting Configure StartUp Projects.... Once the menu pops up, then select Multiple startup projects: and set the action for Content.Client and Content.Server to Start. Once you apply the changes, hitting the big Start button with a green arrow next to it should launch both client and server at the same time.

Note: If you’re having problems with the program not getting built right, you may need to set always build before run. Go to Options Projects and Solutions/Build and Run and change On Run, when projects are out of date to Always build.

In VS you can also use the keys F7 to build the project and F5 to run it.

Visual Studio Code

The C# extension provides a "coreclr" launch type which can be used to run the Content.Server and Content.Client executables in their respective bin/ directories. A compound launch configuration can be used to run the server and client at the same time.

Command Line

Build with dotnet build and run the client and server on different command lines with:

  • dotnet run --project Content.Server
  • dotnet run --project Content.Client

There’s also definitely some way to run two commands at the same time, but you should probably google it.

JetBrains Rider

In Rider you can create a “compound configuration” to run or debug both client and server at the same time. Quite convenient!

Miscellaneous IDE setup

JetBrains Rider

In Rider you can attach the resources directory to the solution so that you can more easily navigate to resource files like prototypes.


Make sure the first three items on top are downloaded. not running

Check that python is installed from the website and not the Microsoft Store. If it’s installed from the Microsoft Store, uninstall it then download and install from the python website.

If you are on Windows and get redirected to the Microsoft Store or encounter a message in your terminal claiming that Python is not installed. This issue may be caused by a stupid Microsoft shortcut. Which you can disable by searching for Manage App Execution Aliases and disabling the two python references

Uninstall .NET Core SDK x86. Install .NET Core SDK x64.

The client and server aren’t available in Visual Studio to configure in Multiple startup projects

This may be because you opened the project as a folder rather than a solution. Make sure you open it as a solution and click the space station 14 .sln file.
