			<return type="void" />
			<argument index="0" name="message" type="String" />
			<description>
				Crashes the engine (or the editor if called within a [code]tool[/code] script). This should [i]only[/i] be used for testing the system's crash handler, not for any other purpose. For general error reporting, use (in order of preference) [method @GDScript.assert], [method @GDScript.push_error] or [method alert]. See also [method kill].
			</description>
		</method>
		<method name="create_instance">
			<return type="int" />
			<argument index="0" name="arguments" type="PoolStringArray" />
			<description>
				Creates a new instance of Pandemonium that runs independently. The [param arguments] 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="PoolStringArray" />
			<argument index="2" name="open_console" type="bool" default="false" />
			<description>
				Creates a new process that runs independently of Pandemonium. It will not terminate if Pandemonium terminates. The path specified in [param path] must exist and be executable file or macOS .app bundle. Platform path resolution will be used. The [param arguments] are used in the given order and separated by a space.
				On Windows, if [param open_console] 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:
				[codeblock]
				var pid = OS.create_process(OS.get_executable_path(), [])
				[/codeblock]
				See [method run] or [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.
				[b]Note:[/b] Equivalent with [method execute] when blocking is set to false.

		<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]. Yielding with [method SceneTree.create_timer] will delay the execution of code placed below the [code]yield[/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]. Yielding with [method SceneTree.create_timer] will delay the execution of code placed below the [code]yield[/code] without affecting the rest of the project (or editor, for [EditorPlugin]s and [EditorScript]s).
				[b]Note:[/b] When [method delay_usec] 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_usec] 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).

				Entry format per line: "Resource Type : Resource Location".
				At the end of the file is a statistic of all used Resource Types.
			</description>
		</method>
		<method name="execute">
			<return type="int" />
			<argument index="0" name="path" type="String" />
			<argument index="1" name="arguments" type="PoolStringArray" />
			<argument index="2" name="blocking" type="bool" default="true" />
			<argument index="3" name="output" type="Array" default="[  ]" />
			<argument index="4" name="read_stderr" type="bool" default="false" />
			<argument index="5" name="open_console" type="bool" default="false" />
			<description>
				Execute the file at the given path with the arguments passed as an array of strings. Platform path resolution will take place. The resolved file must exist and be executable.
				The arguments are used in the given order and separated by a space, so [code]OS.execute("ping", ["-w", "3", "godotengine.org"], false)[/code] will resolve to [code]ping -w 3 godotengine.org[/code] in the system's shell.
				This method has slightly different behavior based on whether the [code]blocking[/code] mode is enabled.
				If [code]blocking[/code] is [code]true[/code], the Pandemonium thread will pause its execution while waiting for the process to terminate. The shell output of the process will be written to the [code]output[/code] array as a single string. When the process terminates, the Pandemonium thread will resume execution.
				If [code]blocking[/code] is [code]false[/code], the Pandemonium thread will continue while the new process runs. It is not possible to retrieve the shell output in non-blocking mode, so [code]output[/code] will be empty.
				On Windows, if [code]open_console[/code] is [code]true[/code] and process is console app, new terminal window will be opened, it's ignored on other platforms.
				The return value also depends on the blocking mode. When blocking, the method will return an exit code of the process. When non-blocking, the method returns a process ID, which you can use to monitor the process (and potentially terminate it with [method kill]). If the process forking (non-blocking) or opening (blocking) fails, the method will return [code]-1[/code] or another exit code.
				Example of blocking mode and retrieving the shell output:
				[codeblock]
				var output = []
				var exit_code = OS.execute("ls", ["-l", "/tmp"], true, output)
				[/codeblock]
				Example of non-blocking mode, running another instance of the project and storing its process ID:
				[codeblock]
				var pid = OS.execute(OS.get_executable_path(), [], false)
				[/codeblock]
				If you wish to access a shell built-in or perform a composite command, a platform-specific shell can be invoked. For example:
				[codeblock]
				OS.execute("CMD.exe", ["/C", "cd %TEMP% &amp;&amp; dir"], true, output)
				[/codeblock]
				[b]Note:[/b] See [method run] or [method create_process] for simpler (but equivalent) alternatives.
				[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.

		</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 Pandemonium 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="PoolStringArray" />
			<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/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:
				[codeblock]
				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]
				    else:
				        # Options without an argument will be present in the dictionary,
				        # with the value set to an empty string.
				        arguments[argument.lstrip("--")] = ""
				[/codeblock]

		<method name="set_window_mouse_passthrough">
			<return type="void" />
			<argument index="0" name="region" type="PoolVector2Array" />
			<description>
				Sets a polygonal region of the window which accepts mouse events. Mouse events outside the region will be passed through.
				Passing an empty array will disable passthrough support (all mouse events will be intercepted by the window, which is the default behavior).
				[codeblock]
				# Set region, using Path2D node.
				OS.set_window_mouse_passthrough($Path2D.curve.get_baked_points())

				# Set region, using Polygon2D node.
				OS.set_window_mouse_passthrough($Polygon2D.polygon)

				# Reset region to default.
				OS.set_window_mouse_passthrough([])
				[/codeblock]
				[b]Note:[/b] On Windows, the portion of a window that lies outside the region is not drawn, while on Linux and macOS it is.
				[b]Note:[/b] This method is implemented on Linux, macOS and Windows.
			</description>
		</method>
		<method name="set_window_title">
			<return type="void" />

				[b]Note:[/b] This method is implemented on HTML5, Linux, macOS and Windows.
			</description>
		</method>
		<method name="shell_open">
			<return type="int" enum="Error" />
			<argument index="0" name="uri" type="String" />
			<description>
				Requests the OS to open a resource with the most appropriate program. For example:
				- [code]OS.shell_open("C:\\Users\name\Downloads")[/code] on Windows opens the file explorer at the user's Downloads folder.
				- [code]OS.shell_open("https://godotengine.org")[/code] opens the default web browser on the official Pandemonium website.
				- [code]OS.shell_open("mailto:example@example.com")[/code] opens the default email client with the "To" field set to [code]example@example.com[/code]. See [url=https://blog.escapecreative.com/customizing-mailto-links/]Customizing [code]mailto:[/code] Links[/url] for a list of fields that can be added.
				Use [method ProjectSettings.globalize_path] to convert a [code]res://[/code] or [code]user://[/code] path into a system path for use with this method.
				[b]Note:[/b] Use [method String.percent_encode] to encode characters within URLs in a URL-safe, portable way. This is especially required for line breaks. Otherwise, [method shell_open] may not work correctly in a project exported to the Web platform.
				[b]Note:[/b] This method is implemented on Android, iOS, HTML5, Linux, macOS and Windows.

		<method name="show_virtual_keyboard">
			<return type="void" />
			<argument index="0" name="existing_text" type="String" default="&quot;&quot;" />
			<argument index="1" name="multiline" type="bool" default="false" />
			<description>
				Shows the virtual keyboard if the platform has one.
				The [code]existing_text[/code] parameter is useful for implementing your own [LineEdit] or [TextEdit], as it tells the virtual keyboard what text has already been typed (the virtual keyboard uses it for auto-correct and predictions).
				The [code]multiline[/code] parameter needs to be set to [code]true[/code] to be able to enter multiple lines of text, as in [TextEdit].
				[b]Note:[/b] This method is equivalent to calling [method show_virtual_keyboard_type] with either default or multiline keyboard type. It is kept for compatibility with previous Pandemonium releases and should be considered [i]deprecated[/i] and replaced by [method show_virtual_keyboard_type].
				[b]Note:[/b] This method is implemented on Android, iOS, UWP, and HTML5.
