Operating System functions.
Operating System functions. OS wraps the most common functionality to communicate with the host operating system, such as the clipboard, video driver, date and time, timers, environment variables, execution of binaries, command line, etc.
Returns [code]true[/code] if the current host platform is using multiple threads.
Shuts down system MIDI driver. [b]Note:[/b] This method is implemented on Linux, macOS and Windows.
Delay execution of the current thread by [code]msec[/code] milliseconds.
Delay execution of the current thread by [code]usec[/code] microseconds.
Dumps the memory allocation ringlist to a file (only works in debug). Entry format per line: "Address - Size - Description".
Dumps all used resources to file (only works in debug). Entry format per line: "Resource Type : Resource Location". At the end of the file is a statistic of all used Resource Types.
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 Godot 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 Godot thread will resume execution. If [code]blocking[/code] is [code]false[/code], the Godot 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. 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% && dir"], true, output) [/codeblock] [b]Note:[/b] This method is implemented on Android, iOS, Linux, macOS and Windows.
Returns the keycode of the given string (e.g. "Escape").
Returns the command line arguments passed to the engine.
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.
Returns current date as a dictionary of keys: [code]year[/code], [code]month[/code], [code]day[/code], [code]weekday[/code], [code]dst[/code] (Daylight Savings Time).

Gets an epoch time value from a dictionary of time values. [code]datetime[/code] must be populated with the following keys: [code]year[/code], [code]month[/code], [code]day[/code], [code]hour[/code], [code]minute[/code], [code]second[/code]. You can pass the output from [method get_datetime_from_unix_time] directly into this function. Daylight Savings Time ([code]dst[/code]), if present, is ignored.
Returns the absolute directory path where user data is written ([code]user://[/code]). On Linux, this is [code]~/.local/share/godot/app_userdata/[project_name][/code], or [code]~/.local/share/[custom_name][/code] if [code]use_custom_user_dir[/code] is set. On macOS, this is [code]~/Library/Application Support/Godot/app_userdata/[project_name][/code], or [code]~/Library/Application Support/[custom_name][/code] if [code]use_custom_user_dir[/code] is set. On Windows, this is [code]%APPDATA%\Godot\app_userdata\[project_name][/code], or [code]%APPDATA%\[custom_name][/code] if [code]use_custom_user_dir[/code] is set. [code]%APPDATA%[/code] expands to [code]%USERPROFILE%\AppData\Roaming[/code]. If the project name is empty, [code]user://[/code] falls back to [code]res://[/code].
Returns [code]true[/code] if an environment variable exists.
Returns [code]true[/code] if the feature for the given feature tag is supported in the currently running instance, depending on platform, build etc. Can be used to check whether you're currently running a debug build, on a certain platform or arch, etc. Refer to the [url=https://docs.godotengine.org/en/latest/getting_started/workflow/export/feature_tags.html]Feature Tags[/url] documentation for more details. [b]Note:[/b] Tag names are case-sensitive.
Returns [code]true[/code] if the Godot binary used to run the project is a [i]debug[/i] export template, or when running in the editor. Returns [code]false[/code] if the Godot binary used to run the project is a [i]release[/i] export template. To check whether the Godot binary used to run the project is an export template (debug or release), use [code]OS.has_feature("standalone")[/code] instead.
Returns [code]true[/code] if the input keycode corresponds to a Unicode character.
Returns [code]true[/code] if the engine was executed with [code]-v[/code] (verbose stdout).
If [code]true[/code], the [code]user://[/code] file system is persistent, so that its state is the same after a player quits and starts the game again. Relevant to the HTML5 platform, where this persistence may be unavailable.
Kill (terminate) the process identified by the given process ID ([code]pid[/code]), e.g. the one returned by [method execute] in non-blocking mode. [b]Note:[/b] This method can also be used to kill processes that were not spawned by the game. [b]Note:[/b] This method is implemented on Android, iOS, Linux, macOS and Windows.

Sets the name of the current thread.
Enables backup saves if [code]enabled[/code] is [code]true[/code].
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 Godot 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] This method is implemented on Android, iOS, HTML5, Linux, macOS and Windows.
- The exit code passed to the OS when the main loop exits. By convention, an exit code of [code]0[/code] indicates success whereas a non-zero exit code indicates an error. For portability reasons, the exit code should be set between 0 and 125 (inclusive). [b]Note:[/b] This value will be ignored if using [method SceneTree.quit] with an [code]exit_code[/code] argument passed.
- If [code]true[/code], the engine optimizes for low processor usage by only refreshing the screen if needed. Can improve battery consumption on mobile.
- The amount of sleeping between frames when the low-processor usage mode is enabled (in microseconds). Higher values will result in lower CPU usage.
