		<method name="create_instance">
			<return type="int" />
			<argument index="0" name="arguments" type="PackedStringArray" />
			<description>
				Creates a new instance of Godot that runs independently. The [code]arguments[/code] are used in the given order and separated by a space.
				If the process creation succeeds, the method will return the new process ID, which you can use to monitor the process (and potentially terminate it with [method kill]). If the process creation fails, the method will return [code]-1[/code].
				[b]Note:[/b] This method is implemented on Android, iOS, Linux, macOS and Windows.
			</description>
		</method>
		<method name="create_process">
			<return type="int" />
			<argument index="0" name="path" type="String" />
			<argument index="1" name="arguments" type="PackedStringArray" />
			<argument index="2" name="open_console" type="bool" default="false" />
			<description>
				Creates a new process that runs independently of Godot. It will not terminate if Godot terminates. The path specified in [code]path[/code] must exist and be executable file or macOS .app bundle. Platform path resolution will be used. The [code]arguments[/code] are used in the given order and separated by a space.
				On Windows, if [code]open_console[/code] is [code]true[/code] and the process is a console app, a new terminal window will be opened. This is ignored on other platforms.
				If the process creation succeeds, the method will return the new process ID, which you can use to monitor the process (and potentially terminate it with [method kill]). If the process creation fails, the method will return [code]-1[/code].
				For example, running another instance of the project:
				[codeblocks]
				[gdscript]
				var pid = OS.create_process(OS.get_executable_path(), [])
				[/gdscript]
				[csharp]
				var pid = OS.CreateProcess(OS.GetExecutablePath(), new string[] {});
				[/csharp]
				[/codeblocks]
				See [method execute] if you wish to run an external command and retrieve the results.
				[b]Note:[/b] This method is implemented on Android, iOS, Linux, macOS and Windows.
				[b]Note:[/b] On macOS, sandboxed applications are limited to run only embedded helper executables, specified during export or system .app bundle, system .app bundles will ignore arguments.

		<method name="delay_msec" qualifiers="const">
			<return type="void" />
			<argument index="0" name="msec" type="int" />
			<description>
				Delays execution of the current thread by [code]msec[/code] milliseconds. [code]msec[/code] must be greater than or equal to [code]0[/code]. Otherwise, [method delay_msec] will do nothing and will print an error message.
				[b]Note:[/b] [method delay_msec] is a [i]blocking[/i] way to delay code execution. To delay code execution in a non-blocking way, see [method SceneTree.create_timer]. Awaiting with [method SceneTree.create_timer] will delay the execution of code placed below the [code]await[/code] without affecting the rest of the project (or editor, for [EditorPlugin]s and [EditorScript]s).
				[b]Note:[/b] When [method delay_msec] is called on the main thread, it will freeze the project and will prevent it from redrawing and registering input until the delay has passed. When using [method delay_msec] as part of an [EditorPlugin] or [EditorScript], it will freeze the editor but won't freeze the project if it is currently running (since the project is an independent child process).
			</description>
		</method>
		<method name="delay_usec" qualifiers="const">
			<return type="void" />
			<argument index="0" name="usec" type="int" />
			<description>
				Delays execution of the current thread by [code]usec[/code] microseconds. [code]usec[/code] must be greater than or equal to [code]0[/code]. Otherwise, [method delay_usec] will do nothing and will print an error message.
				[b]Note:[/b] [method delay_usec] is a [i]blocking[/i] way to delay code execution. To delay code execution in a non-blocking way, see [method SceneTree.create_timer]. Awaiting with [method SceneTree.create_timer] will delay the execution of code placed below the [code]await[/code] without affecting the rest of the project (or editor, for [EditorPlugin]s and [EditorScript]s).

		<method name="execute">
			<return type="int" />
			<argument index="0" name="path" type="String" />
			<argument index="1" name="arguments" type="PackedStringArray" />
			<argument index="2" name="output" type="Array" default="[]" />
			<argument index="3" name="read_stderr" type="bool" default="false" />
			<argument index="4" name="open_console" type="bool" default="false" />
			<description>
				Executes a command. The file specified in [code]path[/code] must exist and be executable. Platform path resolution will be used. The [code]arguments[/code] are used in the given order and separated by a space. If an [code]output[/code] [Array] is provided, the complete shell output of the process will be appended as a single [String] element in [code]output[/code]. If [code]read_stderr[/code] is [code]true[/code], the output to the standard error stream will be included too.
				On Windows, if [code]open_console[/code] is [code]true[/code] and the process is a console app, a new terminal window will be opened. This is ignored on other platforms.
				If the command is successfully executed, the method will return the exit code of the command, or [code]-1[/code] if it fails.
				[b]Note:[/b] The Godot thread will pause its execution until the executed command terminates. Use [Thread] to create a separate thread that will not pause the Godot thread, or use [method create_process] to create a completely independent process.
				For example, to retrieve a list of the working directory's contents:
				[codeblocks]
				[gdscript]
				var output = []
				var exit_code = OS.execute("ls", ["-l", "/tmp"], output)
				[/gdscript]
				[csharp]
				var output = new Godot.Collections.Array();
				int exitCode = OS.Execute("ls", new string[] {"-l", "/tmp"}, output);
				[/csharp]
				[/codeblocks]
				If you wish to access a shell built-in or execute a composite command, a platform-specific shell can be invoked. For example:
				[codeblocks]
				[gdscript]
				var output = []
				OS.execute("CMD.exe", ["/C", "cd %TEMP% &amp;&amp; dir"], output)
				[/gdscript]
				[csharp]
				var output = new Godot.Collections.Array();
				OS.Execute("CMD.exe", new string[] {"/C", "cd %TEMP% &amp;&amp; dir"}, output);
				[/csharp]
				[/codeblocks]
				[b]Note:[/b] This method is implemented on Android, iOS, Linux, macOS and Windows.
				[b]Note:[/b] To execute a Windows command interpreter built-in command, specify [code]cmd.exe[/code] in [code]path[/code], [code]/c[/code] as the first argument, and the desired command as the second argument.
				[b]Note:[/b] To execute a PowerShell built-in command, specify [code]powershell.exe[/code] in [code]path[/code], [code]-Command[/code] as the first argument, and the desired command as the second argument.
				[b]Note:[/b] To execute a Unix shell built-in command, specify shell executable name in [code]path[/code], [code]-c[/code] as the first argument, and the desired command as the second argument.
				[b]Note:[/b] On macOS, sandboxed applications are limited to run only embedded helper executables, specified during export.

		<method name="find_keycode_from_string" qualifiers="const">
			<return type="int" enum="Key" />
			<argument index="0" name="string" type="String" />
			<description>
				Returns the keycode of the given string (e.g. "Escape").
			</description>
		</method>
		<method name="get_cache_dir" qualifiers="const">
			<return type="String" />
			<description>
				Returns the [i]global[/i] cache data directory according to the operating system's standards. On desktop platforms, this path can be overridden by setting the [code]XDG_CACHE_HOME[/code] environment variable before starting the project. See [url=$DOCS_URL/tutorials/io/data_paths.html]File paths in Godot projects[/url] in the documentation for more information. See also [method get_config_dir] and [method get_data_dir].
				Not to be confused with [method get_user_data_dir], which returns the [i]project-specific[/i] user data path.
			</description>
		</method>
		<method name="get_cmdline_args">
			<return type="PackedStringArray" />
			<description>
				Returns the command-line arguments passed to the engine.
				Command-line arguments can be written in any form, including both [code]--key value[/code] and [code]--key=value[/code] forms so they can be properly parsed, as long as custom command-line arguments do not conflict with engine arguments.
				You can also incorporate environment variables using the [method get_environment] method.
				You can set [member ProjectSettings.editor/run/main_run_args] to define command-line arguments to be passed by the editor when running the project.
				Here's a minimal example on how to parse command-line arguments into a dictionary using the [code]--key=value[/code] form for arguments:
				[codeblocks]
				[gdscript]
				var arguments = {}
				for argument in OS.get_cmdline_args():
				    if argument.find("=") &gt; -1:
				        var key_value = argument.split("=")
				        arguments[key_value[0].lstrip("--")] = key_value[1]
				[/gdscript]
				[csharp]
				var arguments = new Godot.Collections.Dictionary();
				foreach (var argument in OS.GetCmdlineArgs())
				{
				    if (argument.Find("=") &gt; -1)
				    {
				        string[] keyValue = argument.Split("=");
				        arguments[keyValue[0].LStrip("--")] = keyValue[1];
				    }
				}
				[/csharp]
				[/codeblocks]
			</description>
		</method>
		<method name="get_config_dir" qualifiers="const">
			<return type="String" />
			<description>
				Returns the [i]global[/i] user configuration directory according to the operating system's standards. On desktop platforms, this path can be overridden by setting the [code]XDG_CONFIG_HOME[/code] environment variable before starting the project. See [url=$DOCS_URL/tutorials/io/data_paths.html]File paths in Godot projects[/url] in the documentation for more information. See also [method get_cache_dir] and [method get_data_dir].
				Not to be confused with [method get_user_data_dir], which returns the [i]project-specific[/i] user data path.
			</description>
		</method>
		<method name="get_connected_midi_inputs">
			<return type="PackedStringArray" />
			<description>
				Returns an array of MIDI device names.
				The returned array will be empty if the system MIDI driver has not previously been initialised with [method open_midi_inputs].
				[b]Note:[/b] This method is implemented on Linux, macOS and Windows.

		</method>
		<method name="get_data_dir" qualifiers="const">
			<return type="String" />
			<description>
				Returns the [i]global[/i] user data directory according to the operating system's standards. On desktop platforms, this path can be overridden by setting the [code]XDG_DATA_HOME[/code] environment variable before starting the project. See [url=$DOCS_URL/tutorials/io/data_paths.html]File paths in Godot projects[/url] in the documentation for more information. See also [method get_cache_dir] and [method get_config_dir].
				Not to be confused with [method get_user_data_dir], which returns the [i]project-specific[/i] user data path.

		</method>
		<method name="get_environment" qualifiers="const">
			<return type="String" />
			<argument index="0" name="variable" type="String" />
			<description>
				Returns the value of an environment variable. Returns an empty string if the environment variable doesn't exist.
				[b]Note:[/b] Double-check the casing of [code]variable[/code]. Environment variable names are case-sensitive on all platforms except Windows.
			</description>
		</method>
		<method name="get_executable_path" qualifiers="const">
			<return type="String" />
			<description>
				Returns the path to the current engine executable.
				[b]Note:[/b] On macOS, always use [method create_instance] instead of relying on executable path.
			</description>
		</method>
		<method name="get_granted_permissions" qualifiers="const">
			<return type="PackedStringArray" />
			<description>
				With this function, you can get the list of dangerous permissions that have been granted to the Android application.
				[b]Note:[/b] This method is implemented on Android.

			<description>
				Returns the given keycode as a string (e.g. Return values: [code]"Escape"[/code], [code]"Shift+Escape"[/code]).
				See also [member InputEventKey.keycode] and [method InputEventKey.get_keycode_with_modifiers].
			</description>
		</method>
		<method name="get_locale" qualifiers="const">
			<return type="String" />
			<description>
				Returns the host OS locale as a string of the form [code]language_Script_COUNTRY_VARIANT@extra[/code]. If you want only the language code and not the fully specified locale from the OS, you can use [method get_locale_language].
				[code]language[/code] - 2 or 3-letter [url=https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes]language code[/url], in lower case.
				[code]Script[/code] - optional, 4-letter [url=https://en.wikipedia.org/wiki/ISO_15924]script code[/url], in title case.
				[code]COUNTRY[/code] - optional, 2 or 3-letter [url=https://en.wikipedia.org/wiki/ISO_3166-1]country code[/url], in upper case.
				[code]VARIANT[/code] - optional, language variant, region and sort order. Variant can have any number of underscored keywords.

			</description>
		</method>
		<method name="get_locale_language" qualifiers="const">
			<return type="String" />
			<description>
				Returns the host OS locale's 2 or 3-letter [url=https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes]language code[/url] as a string which should be consistent on all platforms. This is equivalent to extracting the [code]language[/code] part of the [method get_locale] string.
				This can be used to narrow down fully specified locale strings to only the "common" language code, when you don't need the additional information about country code or variants. For example, for a French Canadian user with [code]fr_CA[/code] locale, this would return [code]fr[/code].
