Property Descriptions
String clipboard The clipboard from the host OS. Might be unavailable on some platforms.

int current_screen The current screen index (starting from 0).

bool delta_smoothing true, the engine filters the time delta measured between each frame, and attempts to compensate for random variation. This will only operate on systems where V-Sync is active.

int exit_code 0 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). Note: This value will be ignored if using SceneTree.quit with an exit_code argument passed.

bool keep_screen_on true, the engine tries to keep the screen on while the game is running. Useful on mobile.

bool low_processor_usage_mode true, the engine optimizes for low processor usage by only refreshing the screen if needed. Can improve battery consumption on mobile.

int low_processor_usage_mode_sleep_usec The amount of sleeping between frames when the low-processor usage mode is enabled (in microseconds). Higher values will result in lower CPU usage.

Vector2 max_window_size (0, 0) to reset to the system default value.

Vector2 min_window_size (0, 0) to reset to the system’s default value. Note: By default, the project window has a minimum size of Vector2(64, 64). This prevents issues that can arise when the window is resized to a near-zero size.

ScreenOrientation screen_orientation The current screen orientation.

String tablet_driver The current tablet driver in use.

bool vsync_enabled true, vertical synchronization (Vsync) is enabled.

bool vsync_via_compositor true and vsync_enabled is true, the operating system’s window compositor will be used for vsync when the compositor is enabled and the game is in windowed mode. Note: This option is experimental and meant to alleviate stutter experienced by some users. However, some users have experienced a Vsync framerate halving (e.g. from 60 FPS to 30 FPS) when using it. Note: This property is only implemented on Windows.

bool window_borderless true, removes the window frame. Note: Setting window_borderless to false disables per-pixel transparency.

bool window_fullscreen true, the window is fullscreen.

bool window_maximized true, the window is maximized.

bool window_minimized true, the window is minimized.

bool window_per_pixel_transparency_enabled true, the window background is transparent and the window frame is removed. get_tree().get_root().set_transparent_background(true) to disable main viewport background rendering. Note: This property has no effect if ProjectSettings.display/window/per_pixel_transparency/allowed setting is disabled. Note: This property is implemented on HTML5, Linux, macOS, Windows, and Android. It can’t be changed at runtime for Android. Use ProjectSettings.display/window/per_pixel_transparency/enabled to set it at startup instead.

Vector2 window_position The window position relative to the screen, the origin is the top left corner, +Y axis goes to the bottom and +X axis goes to the right.

bool window_resizable true, the window is resizable by the user.

Vector2 window_size The size of the window (without counting window manager decorations).
Method Descriptions
alert ( String text, String title=”Alert!” ) Displays a modal dialog box using the host OS’ facilities. Execution is blocked until the dialog is closed.

close_midi_inputs ( ) Shuts down system MIDI driver. Note: This method is implemented on Linux, macOS and Windows.

delay_msec ( int msec ) const msec milliseconds. msec must be greater than or equal to 0. Otherwise, delay_msec will do nothing and will print an error message. Note: delay_msec is a blocking way to delay code execution. To delay code execution in a non-blocking way, see SceneTree.create_timer. Yielding with SceneTree.create_timer will delay the execution of code placed below the yield without affecting the rest of the project (or editor, for EditorPlugins and EditorScripts). Note: When 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 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).

delay_usec ( int usec ) const usec microseconds. usec must be greater than or equal to 0. Otherwise, delay_usec will do nothing and will print an error message. Note: delay_usec is a blocking way to delay code execution. To delay code execution in a non-blocking way, see SceneTree.create_timer. Yielding with SceneTree.create_timer will delay the execution of code placed below the yield without affecting the rest of the project (or editor, for EditorPlugins and EditorScripts). Note: When 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 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).

int execute ( String path, PoolStringArray arguments, bool blocking=true, Array output=[ ], bool read_stderr=false ) 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. OS.execute("ping", ["-w", "3", "godotengine.org"], false) will resolve to ping -w 3 godotengine.org in the system’s shell. blocking mode is enabled. blocking is true, 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 output array as a single string. When the process terminates, the Godot thread will resume execution. blocking is false, the Godot thread will continue while the new process runs. It is not possible to retrieve the shell output in non-blocking mode, so output will be empty. kill). If the process forking (non-blocking) or opening (blocking) fails, the method will return -1 or another exit code. Example of blocking mode and retrieving the shell output:
```
var output = []var exit_code = OS.execute("ls", ["-l", "/tmp"], true, output)
```
Example of non-blocking mode, running another instance of the project and storing its process ID:
```
var pid = OS.execute(OS.get_executable_path(), [], false)
```
If you wish to access a shell built-in or perform a composite command, a platform-specific shell can be invoked. For example:
```
OS.execute("CMD.exe", ["/C", "cd %TEMP% && dir"], true, output)
```

The returned string may also be falsified using external programs, so do not rely on the string returned by get_unique_id for security purposes. Note: Returns an empty string on HTML5 and UWP, as this method isn’t implemented on those platforms yet.

int get_unix_time ( ) const Returns the current UNIX epoch timestamp in seconds. Important: This is the system clock that the user can manually set. Never use this method for precise time calculation since its results are also subject to automatic adjustments by the operating system. Always use get_ticks_usec or get_ticks_msec for precise time calculation instead, since they are guaranteed to be monotonic (i.e. never decrease).

int get_unix_time_from_datetime ( Dictionary datetime ) const Gets an epoch time value from a dictionary of time values. datetime must be populated with the following keys: year, month, day, hour, minute, second. 0 is returned. If some keys are omitted, they default to the equivalent values for the UNIX epoch timestamp 0 (1970-01-01 at 00:00:00 UTC). get_datetime_from_unix_time directly into this function.

show_virtual_keyboard ( String existing_text=””, bool multiline=false ) Shows the virtual keyboard if the platform has one. existing_text 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). multiline parameter needs to be set to true to be able to enter multiple lines of text, as in TextEdit. Note: This method is implemented on Android, iOS and UWP.
