Welcome to Barotrauma's GitHub repository! If you're here to report an issue or to contribute to the development, please read the instructions below before you do.
Please check our FAQ in case the question has already been answered. If not, you can post the question on the Barotrauma discussion forum or stop by at our Discord Server.
If you've encountered a bug, you can report it in the issue tracker. Please follow the instructions in the issue template to make it easier for us to diagnose and fix the issue.
Before you start doing modifications to the code or submitting pull requests to the repository, it is important that you've read and understood (at least the human-readable summary part) of our EULA. To sum it up, Barotrauma is not an open source project in the sense of free, open source software that you can freely distribute or reuse. Even though the early versions of the game have been available for free, the game will eventually have a price tag. If you're not comfortable with your contributions potentially being used in a commercial product, do not submit pull requests to the repository.
You need a version of Visual Studio that supports C# 6.0 to compile game. If you don't have a compatible version of Visual Studio installed, you can get Visual Studio Community 2017 from the following link: https://visualstudio.microsoft.com/downloads/
Make sure you select ".NET desktop development" during the install process to make sure you have the required features to work with Barotrauma.
All that is required to build Barotrauma on Linux is the mono-devel package that you can install by following the instructions on the following page: https://www.mono-project.com/download/stable/#download-lin
You may optionally install MonoDevelop to navigate and modify the solution.
We use NuGet to make the solution download most of the required libraries and dependencies automatically, but you also need to make sure you have the OpenAL audio library installed.
If you're on Windows, you can get OpenAL from the following link: https://www.openal.org/downloads/oalinst.zip
Barotrauma's source code is split up into three projects: ClientCode, Server and SharedCode. The non-code assets (i.e. textures, sound files, miscellaneous XML) are mainly found in the SharedContent project.
The client project includes the code only required by the client executable: graphics-related code, audio, particle effects and such. The server project includes logic that's only needed by the dedicated server executable. The shared project contains most of the gameplay, physics and networking logic and everything else that's needed by both the client executable and the dedicated server.
Before building, you should choose the build configuration. The available configurations are DebugWindows, DebugMac, DebugLinux, ReleaseWindows, ReleaseMac and ReleaseLinux. Additionally, unless you want to work on the dedicated server, you may want to make sure WindowsClient, MacClient or LinuxClient are selected as the startup project.
The BarotraumaShared\Content folder, which contains Barotrauma's art, item XMLs, sounds, and other assets, is not included in the GitHub repository. If you have a legal copy of the game, you can copy the Content folder from the game's files to BarotraumaShared\Content.
The debug build configurations include some features that make debugging and testing a little easier: things such as additional console commands, being able to move the submarine with the IJKL keys and allowing clients to use any console command in multiplayer. The debug builds don't create crash reports when an unhandled exception occurs - the intention behind this is to allow exceptions to be caught by the debugger instead of having the game close and write a report.
To build through the command line (recommended if you're on Linux), use the following command:
msbuild Barotrauma_Solution.sln /property:Configuration=CONFIGURATION /property:Platform=x64
We (loosely) follow the C# naming and coding conventions recommended by Microsoft.

We don't have a strict format for commit messages, but please try to make them informative - what did you change and why. It's also recommended that you reference any relevant commits and issue reports in the commit message. If you're fixing a bug caused by a specific commit, mention that commit ("the method added in a1b9b7z didn't take into account things A and B..."), or if you're fixing something that's listed in the issue tracker, mention that issue ("Fixes #123")
