Batch mode and built-in coroutine compatibility

Command line arguments

You can run Unity from the command line (from the macOS Terminal or the Windows Command Prompt).

Launching Unity

On macOS, type the following into the Terminal to launch Unity:

/Applications/Unity/Unity.app/Contents/MacOS/Unity

On Windows, type the following into the Command Prompt to launch Unity:

"C:\Program Files\Unity\Editor\Unity.exe"

When you launch Unity like this, it receives commands and information on startup, which can be very useful for test suites, automated builds and other production tasks. Note: Use the same method to launch standalone Unity applications.

Launching Unity silently

On macOS, type the following into the Terminal to silently launch Unity:

/Applications/Unity/Unity.app/Contents/MacOS/Unity -quit -batchmode -serial SB-XXXX-XXXX-XXXX-XXXX-XXXX -username 'JoeBloggs@example.com' -password 'MyPassw0rd'

Note: If you use continuous integration (CI) tools like Jenkins to activate via the command line, add the -nographics flag to prevent a WindowServer error.

On Windows, type the following into the Command Prompt to silently launch Unity:

"C:\Program Files\Unity\Editor\Unity.exe" -batchmode -username name@example.edu.uk - password XXXXXXXXXXXXX -serial E3-XXXX-XXXX-XXXX-XXXX-XXXX –quit

Returning the license to the license server

On macOS, type the following into the Terminal to return the license:

/Applications/Unity/Unity.app/Contents/MacOS/Unity -quit -batchmode -returnlicense

На Windows:

"C:\Program Files\Unity\Editor\Unity.exe" -quit -batchmode -returnlicense

Returning the license is useful when you no longer want to use Unity on the machine, and want to use the same license on another machine.

Create a license activation file and import license file by command

On macOS, type the following into the Terminal:

/Applications/Unity/Unity.app/Contents/MacOS/Unity -batchmode -createManualActivationFile -logfile

/Applications/Unity/Unity.app/Contents/MacOS/Unity -batchmode -manualLicenseFile <yourulffile> -logfile

On Windows, type the following into the Command Prompt:

"C:\Program Files\Unity\Editor\Unity.exe" -batchmode -createManualActivationFile -logfile

"C:\Program Files\Unity\Editor\Unity.exe" -batchmode -manualLicenseFile <yourulffile> -logfile

For more details, read the Manual Activation Guide.

Опции

You can run the Editor and build Unity applications with additional commands and information on startup. This section describes the command line options available.

Command	Details
`-accept-apiupdate`	Use this command line option to specify that APIUpdater should run when Unity is launched in batch mode. Example: `unity.exe -accept-apiupdate -batchmode [other params]` The APIUpdater will not run if you omit this command line argument when you launch Unity in batch mode. This can lead to compiler errors.
`-batchmode`	Run Unity in batch mode. Always use this in conjunction with the other command line arguments to ensure no pop-up windows appear and eliminate the need for any human intervention. When an exception occurs during execution of the script code, the Asset server updates fail, or other operations fail, Unity immediately exits with return code 1. Note that in batch mode, Unity sends a minimal version of its log output to the console. However, the Log Files still contain the full log information. You cannot open a project in batch mode while the Editor has the same project open; only a single instance of Unity can run at a time. To check whether the Editor or Standalone Player is running in batch mode, use the Application.isBatchMode operator. If the project has not yet been imported when using `-batchmode`, the target platform is the default one. To force a different platform, use the `-buildTarget` option.
`-buildLinux64Player <pathname>`	Собрать 64-битное приложение для Linux (например, -buildLinux64Player path/to/your/build).
`-buildOSXUniversalPlayer <pathname>`	Build a 64-bit standalone Mac OSX player (for example, `-buildOSXUniversalPlayer path/to/your/build.app`).
`-buildTarget <name>`	Select an active build target before loading a project. Possible options are: Standalone, Win, Win64, OSXUniversal, Linux64, iOS, Android, WebGL, XboxOne, PS4, WindowsStoreApps, Switch, tvOS.
`-buildWindowsPlayer <pathname>`	Собрать 32-битное приложение Windows (например, -buildWindowsPlayer path/to/your/build.exe).
`-buildWindows64Player <pathname>`	Собрать 64-битное приложение Windows (например, -buildWindows64Player path/to/your/build.exe).
`-createProject <pathname>`	Создать пустой проект по заданному пути.
`-deepprofiling`	Enable Deep Profiling option for the CPU profiler.
`-disable-assembly-updater <assembly1 assembly2>`	Specify a space-separated list of assembly names as parameters for Unity to ignore on automatic updates. The space-separated list of assembly names is optional: pass the command line options without any assembly names to ignore all assemblies, as in example 1. Example 1 `unity.exe -disable-assembly-updater` Example 2 `unity.exe -disable-assembly-updater A1.dll subfolder/A2.dll` Example 2 has two assembly names, one with a pathname. Example 2 ignores `A1.dll`, no matter what folder it is stored in, and ignores `A2.dll` only if it is stored under `subfolder` folder: If you list an assembly in the `-disable-assembly-updater` command line parameter (or if you don’t specify assemblies), Unity logs the following message to Editor.log: `[Assembly Updater] warning: Ignoring assembly [assembly_path] as requested by command line parameter.").` Use this to avoid unnecessary API Updater overheads when importing assemblies. It is useful for importing assemblies which access a Unity API when you know the Unity API doesn’t need updating. It is also useful when importing assemblies which do not access Unity APIs at all (for example, if you have built your source code, or some of it, outside of Unity, and you want to import the resulting assemblies into your Unity project). Note: If you disable the update of any assembly that does need updating, you may get errors at compile time, run time, or both, that are hard to track.
`-diag-debug-shader-compiler`	Unity launches only one instance of the Shader Compiler, and forces its timeout to be one hour. Useful for debugging Shader Compiler issues.
`-enableCodeCoverage`	Enables code coverage and allows access to the Coverage API.
`-executeMethod <ClassName.MethodName>` or `-executeMethod <NamespaceName.ClassName.MethodName>`	Execute the static method as soon as Unity opens the project, and after the optional Asset server update is complete. You can use this to do tasks such as continuous integration, performing Unit Tests, making builds or preparing data. To return an error from the command line process, either throw an exception which causes Unity to exit with return code 1, or call EditorApplication.Exit with a non-zero return code. To pass parameters, add them to the command line and retrieve them inside the function using `System.Environment.GetCommandLineArgs`. To use `-executeMethod`, you need to place the enclosing script in an Editor folder. The method you execute must be defined as static.
`-exportPackage <exportAssetPath1 exportAssetPath2 ExportAssetPath3 exportFileName>`	Export a package, given a path (or set of given paths). In this example `exportAssetPath` is a folder (relative to to the Unity project root) to export from the Unity project, and `exportFileName` is the package name. Currently, this option only exports whole folders at a time. You normally need to use this command with the `-projectPath` argument.
`-force-d3d11` (Windows only)	Make the Editor use Direct3D 11 for rendering. Normally the graphics API depends on Player Settings (typically defaults to D3D11).
`-force-d3d12` (Windows only)	Make the Editor use Direct3D 12 for rendering. Normally the graphics API depends on Player Settings.
`-force-device-index`	When using Metal, make the Editor use a particular GPU device by passing it the index of that GPU (macOS only).
`-force-metal`	Make the Editor use Metal as the default graphics API (macOS only).
`-force-glcore`	Make the Editor use OpenGL 3/4 core profile for rendering. The Editor tries to use the best OpenGL version available and all OpenGL extensions exposed by the OpenGL drivers. If the platform isn’t supported, Direct3D is used.
`-force-glcoreXY`	Similar to `-force-glcore`, but requests a specific OpenGL context version. Accepted values for XY: 32, 33, 40, 41, 42, 43, 44 or 45.
`-force-gles` (Windows only)	Make the Editor use OpenGL for Embedded Systems for rendering. The Editor tries to use the best OpenGL ES version available, and all OpenGL ES extensions exposed by the OpenGL drivers.
`-force-glesXY` (Windows only)	Similar to `-force-gles`, but requests a specific OpenGL ES context version. Accepted values for XY: 30, 31 or 32.
`-force-vulkan`	Make the Editor use Vulkan for rendering. Normally the graphics API depends on Player Settings.
`-force-clamped`	Use this with `-force-glcoreXY` to prevent Unity from checking for additional OpenGL extensions, allowing it to run between platforms with the same code paths.
`-force-free`	Make the Editor run as if there is a free Unity license on the machine, even if a Unity Pro license is installed.
`-force-low-power-device` (macOS only)	If you use Metal, make the Editor use a low power device.
`-importPackage <pathname>`	Импортирует выбранный пакет. Окно импорта показываться не будет.
`-job-worker-count <N>`	Specify the maximum thread count for the Unity JobQueue Job Worker Count. You can also specify it as `job-worker-count=<N>` in `boot.config` for the Unity Standalone Player.
`-logFile <pathname>`	Specify where Unity writes the Editor or Windows/Linux/OSX standalone log file. To output to the console, specify `-` for the path name. On Windows, specify `-` option to make the output go to `stdout`, which is not the console by default.
`-nographics`	When you run this in batch mode, it does not initialize the graphics device. You can then run automated workflows on machines that don’t have a GPU. Automated workflows only work when you have a window in focus, otherwise you can’t send simulated input commands. `-nographics` does not allow you to bake GI as Enlighten requires GPU acceleration.
`-noUpm`	Disables the Unity Package Manager.
`-openfile <path>`	Open the project from a path to a scene or package file. Alternative is to use `-projectPath` argument.
`-password <password>`	Enter a password into the log-in form during the activation of the Unity Editor.
`-profiler-enable`	Profile the start-up of a Player or the Editor. When you use this argument with a Player, it has the same effect as building the Player with the Autoconnect Profiler option enabled in Build Settings. When you use this argument with the Editor, it starts collecting and displaying Profiler information in the Profiler window on start-up of the Editor.
`-profiler-log-file <Path/To/Log/File.raw>`	This argument sets up the Unity Profiler to stream the profile data to a .raw file on startup. It works for both Players and the Editor.
`-profiler-capture-frame-count <NumberOfFrames>`	This argument sets how many frames the Profiler should capture in a profile when streaming to a .raw file on start-up. It only works on Players.
`-profiler-maxusedmemory`	By default, `maxUsedMemory` for the Unity Profiler is 16MB for Players and 256MB for the Editor. You can use this argument to set the `maxUsedMemory` parameter to a custom size at start-up (for example, `-profiler-maxusedmemory 16777216`). The size is set in bytes.
`-projectPath <pathname>`	Open the project at the given path. If pathname contains spaces, enclose it in quotes.
`-quit`	Quit the Unity Editor after other commands have finished executing. This can cause error messages to be hidden (however, they still appear in the Editor.log file).
`-returnlicense`	Return the currently active license to the license server. You should wait a few seconds before Unity removes the license file, because it needs to communicate with the license server.
`-serial <serial>`	Activate Unity with the specified serial key. When you use this to automatically activate Unity, you must pass the `-batchmode`, and it is good practice to pass the `-quit` argument. You should wait a few seconds before Unity removes the license file, because it needs to communicate with the license server. Make sure that license file folder exists, and it has appropriate permissions before you run Unity with this argument. If activation fails, see the Editor.log for info.
`-setDefaultPlatformTextureFormat` (Android only)	Set the default texture compression to the desired format before you import a texture or build the project. This is so you don’t have to import the texture again with the format you want. The available formats are dxt, pvrtc, atc, etc, etc2, and astc.
`-silent-crashes`	Prevent Unity from displaying the dialog that appears when a Standalone Player crashes. This argument is useful when you want to run the Player in automated builds or tests, where you don’t want a dialog prompt to obstruct automation.
`-stackTraceLogType`	Allow detailed debugging. All settings allow None, Script Only and Full to be selected. (for example, `-stackTraceLogType Full`)
`-testPlatform`, `-testResults`, `-runTests`	Run tests. See Unity Test Runner documentation.
`-username <username>`	Enter a username into the log-in form during the activation of the Unity Editor.
`-vcsMode <mode>`	Set version control mode for this session. Available modes are `"Visible Meta Files"`, `"Hidden Meta Files"`, `Perforce`, and `PlasticSCM`. Additional flags can be used to fill out the configuration fields for the given version control mode. These flags are based on the Provider.GetActiveConfigFields method. For example, you can use the `-vcPerforceUsername`, `-vcPerforcePassword`, `-vcPerforceWorkspace` and `-vcPerforceServer` to set the Perforce username, workspace and server fields. Note: `<mode>` arguments that contain spaces must be wrapped in double quotes (`"`).
`-EnableCacheServer`	Tells Unity to enable usage of the newer Accelerator Cache Server. You must also use `-cacheServerEndpoint` to specify the address.
`-cacheServerEndpoint`	Specifies the endpoint address if you are using the newer Accelerator Cache Server. Example: `-cacheServerEndpoint 127.0.0.1:10080`. This overrides any configuration stored in the Editor Preferences. Use this to connect multiple instances of Unity to different Cache Servers.
`-cacheServerNamespacePrefix`	Set the namespace prefix for the newer Accelerator Cache Server. Used to group data together on the Cache Server. Example: `-cacheServerNamespacePrefix MyProject`
`-cacheServerEnableDownload`	Enable downloading from the newer Accelerator Cache Server. Example: `-cacheServerEnableDownload true`
`-cacheServerEnableUpload`	Enable uploading to the newer Accelerator Cache Server. Example: `-cacheServerEnableUpload false`
`-CacheServerIPAddress <host:port>`	Enables usage of the older (v1) Cache Server, and specifies the IP Address to connect to on startup. This overrides any configuration stored in the Editor Preferences. Use this to connect multiple instances of Unity to different v1 Cache Servers.

Пример использования

C# script in the project:

using UnityEditor;
class MyEditorScript
{
     static void PerformBuild ()
     {
         string[] scenes = { "Assets/MyScene.unity" };
         BuildPipeline.BuildPlayer(scenes, ...);
     }
}

The following command executes Unity in batch mode, executes the MyEditorScript.PerformBuild method, and then quits upon completion. Because the

Windows:

"C:\Program Files\Unity\Editor\Unity.exe" -quit -batchmode -projectPath "C:\Users\UserName\Documents\MyProject" -executeMethod MyEditorScript.PerformBuild

Mac OS:

Аргументы командной строки для самостоятельного приложения Unity

You should only use these under special circumstances, or when directed by Unity Support.

Command Details

-enableIncompatibleAssetDowngrade Use this when you have Assets made by a newer, incompatible version of Unity, that you want to downgrade to work with your current version of Unity. When you enable this, Unity presents you with a dialog asking for confirmation of this downgrade if you attempt to open a project that would require it.
Note: This procedure is unsupported and highly risky, and should only be used as a last resort.

Аргументы командной строки для самостоятельного приложения Unity

Приложения собранные в Unity так же воспринимают некоторые аргументы командной строки:

Command	Details
`-monitor N`	Run Standalone Player on the specified monitor, indicated by a 1-based index number.
`-batchmode`	Run the game in “headless” mode. The game does not display anything or accept user input. This is useful for running servers for networked games.
`-force-d3d11` (Windows only)	Принуждает игру использовать для рендеринга Direct3D 11.
`-force-d3d11-singlethreaded`	Force DirectX 11.0 to be created with a `D3D11_CREATE_DEVICE_SINGLETHREADED` flag.
`-force-d3d12` (Windows only)	Force the game to use Direct3D 12 for rendering.
`-force-device-index`	Make the Standalone Player use a particular GPU device by passing it the index of that GPU. This option is supported for D3D11, D3D12, Metal, and Vulkan graphics APIs, but is not supported for OpenGL.
`-force-metal` (macOS only)	Make the Standalone Player use Metal as the default graphics API.
`-force-glcore`	Force the game to use OpenGL core profile for rendering. The Editor tries to use the best OpenGL version available, and all OpenGL extensions exposed by the OpenGL drivers. If the platform isn’t supported, Direct3D is used.
`-force-glcoreXY`	Similar to `-force-glcore`, but requests a specific OpenGL context version. Accepted values for XY: 32, 33, 40, 41, 42, 43, 44 or 45.
`-force-vulkan`	Force the game to use Vulkan for rendering.
`-force-clamped`	Use this together with `-force-glcoreXY` to prevent checking for additional OpenGL extensions, allowing it to run between platforms with the same code paths.
`-force-low-power-device` (macOS only)	Make the Standalone Player use a low power device.
`-force-wayland`	Activate experimental Wayland support when running a Linux player.
`-nographics`	When you run this in batch mode, it does not initialize a graphics device. This makes it possible to run your automated workflows on machines that don’t have a GPU.
`-nolog`	Do not produce an output log. Normally Unity writes the `output_log.txt` in the Log Files folder, where the Debug.Log output is printed.
`-no-stereo-rendering`	Turn off stereo rendering.
`-parentHWND <HWND> delayed` (Windows only)	Embed the Windows Standalone application into another application. When you use this, you need to pass the parent application’s window handle (‘HWND’) to the Windows Standalone application. When you pass `-parentHWND 'HWND' delayed`, the Unity application is hidden while it is running. You must also call SetParent from the Microsoft Developer library for Unity in the application. Microsoft’s `SetParent` embeds the Unity window. When it creates Unity processes, the Unity window respects the position and size provided as part of the Microsoft’s STARTUPINFO structure. To resize the Unity window, check its GWLP_USERDATA in Microsoft’s `GetWindowLongPtr` function. Its lowest bit is set to 1 when the graphics initialize and it’s safe to resize. Its second lowest bit is set to 1 after the Unity splash screen finishes displaying. For more information, see this example: EmbeddedWindow.zip
`-popupwindow`	Create the window as a a pop-up window, without a frame. This command is not supported on macOS.
`-screen-fullscreen`	Заменяет стандартную ширину экрана. Это должно целое число из диапазона поддерживаемого разрешения.
`-screen-height`	Заменяет стандартную высоту экрана. Это должно целое число из диапазона поддерживаемого разрешения.
`-screen-width`	Заменяет стандартную ширину экрана. Это должно целое число из диапазона поддерживаемого разрешения.
`-screen-quality`	Override the default screen quality. Example usage would be: `/path/to/myGame -screen-quality Beautiful`. The supported options match the Quality Settings names.
`-single-instance` (Linux and Windows only)	Run only one instance of the application at the time. If another instance is already running then launching it again with `-single-instance` focuses the existing one.
`-vrmode <devicetype>`	Launch with a specific VR device. See Virtual Reality for details.
`-window-mode` (Windows only)	Override fullscreen windowing mode. Accepted values are `exclusive` or `borderless`. See Standalone Player settings for details.

Universal Windows Platform command line arguments

Universal Windows Apps don’t accept command line arguments by default, so to pass them you need to call a special function from MainPage.xaml.cs/cpp or MainPage.cs/cpp. For example:

appCallbacks.AddCommandLineArg("-nolog");

You should call this before the appCallbacks.Initialize() function.

Command	Details
`-nolog`	Не записывает UnityPlayer.log.
