JetBrains Rider

JetBrains Rider is a commercial JetBrains IDE for C++, C# and GDScript that uses the same solution system as Visual Studio.

INFO

This documentation is for contributing to the game engine, not for using JetBrains Rider as a C# or GDScript editor. To code C# or GDScript in an external editor, see Configuring an external editor.

Importing the project

TIP

If you already use Visual Studio as your main IDE, you can use the same solution file in Rider. Rider and Visual Studio use the same solution format, so you can switch between the two IDEs without rebuilding the solution file. Debug configurations need to be changed when going from one IDE to another.

If you are starting from the scratch, please follow Building from source, specifically:

• Install all the dependencies.

• Figure out the scons command for compiling to target a specific platform.

Provide scons with additional arguments to request a solution file generation:

• Add vsproj=yes dev_build=yes to the scons command

The vsproj parameter signals that you want Visual Studio solution generated. The dev_build parameter ensures the debug symbols are included, allowing to e.g. step through code using breakpoints.

• Open the generated godot.sln in Rider.

INFO

Ensure that the appropriate Solution configuration is selected on the Rider toolbar. It affects resolve of the SDKs, code analysis, build, run, etc.

Compiling and debugging the project

Rider comes with a built-in debugger that can be used to debug the Godot project. You can launch the debugger by pressing the Debug icon at the top of the screen, this only works for the Project Manager, if you want to debug the editor, you need to configure the debugger first.

• Click on the Godot > Edit Configurations option at the top of the screen.

• Ensure the following values for the C++ Project Run Configuration:

  • Exe Path : $(LocalDebuggerCommand)
  • Program Arguments: -e --path <path to the Godot project>
  • Working Directory: $(LocalDebuggerWorkingDirectory)
  • Before Launch has a value of "Build Project"

This will tell the executable to debug the specified project without opening the Project Manager. Use the root path to the project folder, not project.godot file path.

• Finally click on "Apply" and "OK" to save the changes.

• When you press the Debug icon at the top of the screen, JetBrains Rider will launch the Godot editor with the debugger attached.

Alternatively you can use Run > Attach to Process to attach the debugger to a running Godot instance.

• You can find the Godot instance by searching for godot.editor and then clicking Attach with LLDB

Debug visualizers

Debug visualizers customize how complex data structures are displayed during debugging. For Windows "natvis" (short for "Native Visualization") built-in with Godot are automatically used. For other operating systems, similar functionality can be setup manually.

Please follow RIDER-123535.

Unit testing

Leverage Rider Unit testing support. Please refer to the instructions.

Profiling

Please refer to the profiling instructions.
