Building

Common

  • A copy of the game is required (obviously)

  • BepInEx and SpaceWarp v0.4.0 should be installed

  • By default the game is expected to be installed in C:\Program Files (x86)\Steam\steamapps\common\Kerbal Space Program 2 if it is somewhere else you have to set a KSP2_BASE_DIR enviroment variable or provide it as a global property to msbuild

Windows

  • Install Visual Studio 2022 Community edition (or higher)

    • Add Commandline Tools and support for .NET 8.0 target

In the ‘VS` commmand line or powershell

dotnet build  -restore -Property:Configuration=Release

should build everything to the dist folder

There are powershell helper script build.ps1 and clean.ps1 to do this with slightly better control.

Linux

Note: Running the game on linux is officially not supported.

If you have installed the game via steam/proton you should set an environment variable:

export KSP2_BASE_DIR=$HOME/.local/share/Steam/steamapps/common/Kerbal\ Space\ Program\ 2

  • Install dotnet-sdk and dotnet-host for version 8.0

    • Package names will vary on distribution. For ArchLinux based distributions this would be dotnet-sdk and dotnet-host

msbuild -t:build,test -restore -Property:Configuration=Release

should build everything to the dist folder

There are some helper scripts build.sh and clean.sh to do this with slightly better control.

IDE

Depending on your IDE you might have to set a global msbuild property KSP2_BASE_DIR. Otherwise, I had no problem importing the solution to VS Code 2022 or Rider.
