Run/Debug Configuration: Standalone Player

Last modified: 13 December 2022

note

Please do not confuse run/debug configurations with build configurations.

Create: Run | Edit Configurations | Add New Configuration | Standalone Player

Use this configuration for Standalone Player and Unity Editor (in some rare cases like running batchMode).

Exe path:

Specify the path to the game executable. Alternatively, you can run one more Unity Editor instance. To do so, you need to specify the path to the Unity Editor executable instead of the game.

Program arguments:

Arguments that will be passed to the executable when the configuration is started.

Multiple arguments should be separated with whitespaces.

Working directory:

The working directory is automatically set to the bin/debug path of the selected target project, but you can change it if needed.

Environmental variables:

Here you can specify custom environment variables for the target executable.

.NET runtime arguments:

Both dotnet and Mono support setting custom runtime arguments when launching an application. For example Mono supports many runtime arguments to customize how your application is run. You can select the garbage collector to be used (--gc=boehm or --gc=sgen), on macOS you can select the runtime architecture to be used (--arch=32 or --arch=64), and more.

Use mono runtime

If you are working on Windows, you can check how your application works with the mono runtime. JetBrains Rider will use the mono executable specified on the Build, Execution, Deployment | Toolset and Build page of JetBrains Rider settings Ctrl+Alt+S.

To debug with mono runtime, you need:

  • Mono 4.2+

  • Portable PDB in your projects — <debugtype>portable</debugtype> in the .csproj file, or alternatively, generate mdb with pdb2mdb.

Use external console:

By default, the output of .NET and Mono applications is shown in the Run or Debug window. Use this checkbox to show the output in an external window.

This checkbox does not affect classic .NET application types (for example, .NET Console Application) — their output in always shown in an external window.

Common settings

When you edit a run configuration (but not a run configuration template), you can specify the following options:

Item

Description

Name

Specify a name for the run configuration to quickly identify it among others when editing or running.

Allow multiple instances

Allow running multiple instances of this run configuration in parallel.

By default, it is disabled, and when you start this configuration while another instance is still running, JetBrains Rider suggests stopping the running instance and starting another one. This is helpful when a run configuration consumes a lot of resources and there is no good reason to run multiple instances.

Store as project file

Save the file with the run configuration settings to share it with other team members. The default location is .idea/runConfigurations. However, if you do not want to share the .idea directory, you can save the configuration to any other directory within the project.

By default, it is disabled, and JetBrains Rider stores run configuration settings in .idea/workspace.xml.

Toolbar

The tree view of run/debug configurations has a toolbar that helps you manage configurations available in your solution as well as adjust default configurations templates.

Shortcut

Description

the Add button

Ctrl+N

Create a run/debug configuration.

the Remove button

Ctrl+R, D

Delete the selected run/debug configuration. Note that you cannot delete default configurations.

Copy

Ctrl+D

Create a copy of the selected run/debug configuration. Note that you create copies of default configurations.

Save configuration

The button is displayed only when you select a temporary configuration. Click this button to save a temporary configuration as permanent.

Move into new folder / Create new folder

Move into new folder / Create new folder. You can group run/debug configurations by placing them into folders.

To create a folder, select the configurations within a category, click Folder, and specify the folder name. If only a category is in focus, an empty folder is created.

Then, to move a configuration into a folder, between the folders or out of a folder, use drag or Move Up and Move Down buttons.

To remove grouping, select a folder and click Remove Configuration.

Sort configurations

Click this button to sort configurations in the alphabetical order.

Before launch

In this area, you can specify tasks to be performed before starting the selected run/debug configuration. The tasks are performed in the order they appear in the list.

Shortcut

Description

the Add button

Ctrl+N

Click this icon to add one of the following available tasks:

  • Run External tool: select to run an external application. In the dialog that opens, select one or multiple applications you want to run. If it is not defined in JetBrains Rider yet, add its definition.

  • Run Another Configuration: select to execute another run/debug configuration and wait until it finishes before starting the current configuration. If you want to run several configurations in parallel, use a compound run/debug configuration.

  • Build solution: select this option to build the solution before launching the configuration.

  • Run File Watchers: select this option to have JetBrains Rider apply all the currently active File Watchers.

  • Run Grunt task: select this option to run a Grunt task.

    In the Grunt task dialog that opens, specify the Gruntfile.js where the required task is defined, select the task to execute, and specify the arguments to pass to the Grunt tool.

    Specify the location of the Node.js interpreter, the parameters to pass to it, and the path to the grunt-cli package.

  • Run gulp task: select this option to run a Gulp task.

    In the Gulp task dialog that opens, specify the Gulpfile.js where the required task is defined, select the task to execute, and specify the arguments to pass to the Gulp tool.

    Specify the location of the Node.js interpreter, the parameters to pass to it, and the path to the gulp package.

  • Run npm script: select this option to execute an npm script.

    In the NPM Script dialog that opens, specify the npm run/debug configuration settings.

  • Compile TypeScript: select to run the built-in TypeScript compiler and thus make sure that all the changes you made to your TypeScript code are reflected in the generated JavaScript files. In the TypeScript Compile Settings dialog that opens, select or clear the Check errors checkbox to configure the behaviour of the compiler in case any errors are detected:

    • If the Check errors checkbox is selected, the compiler will show all the errors and the run configuration will not start.

    • If the Check errors checkbox is cleared, the compiler will show all the detected errors but the run configuration still will be launched.

  • Generate CoffeeScript Source Maps: select this option to generate the source maps for your CoffeeScript sources. In the dialog that opens, specify where your CoffeeScript source files are located.

  • Upload files to Remote Host: select this option to have the application files automatically uploaded to the server according to the default server access configuration.
