Property Descriptions

Default""
Setterset_clipboard(value)
Getterget_clipboard()

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


  • int current_screen
Default0
Setterset_current_screen(value)
Getterget_current_screen()

The current screen index (starting from 0).


Default0
Setterset_exit_code(value)
Getterget_exit_code()

The exit code passed to the OS when the main loop exits. By convention, an exit code of 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.


Defaulttrue
Setterset_keep_screen_on(value)
Getteris_keep_screen_on()

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


  • bool low_processor_usage_mode
Defaultfalse
Setterset_low_processor_usage_mode(value)
Getteris_in_low_processor_usage_mode()

If 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
Default6900
Setterset_low_processor_usage_mode_sleep_usec(value)
Getterget_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.


DefaultVector2( 0, 0 )
Setterset_max_window_size(value)
Getterget_max_window_size()

The maximum size of the window (without counting window manager decorations). Does not affect fullscreen mode. Set to (0, 0) to reset to the system default value.


DefaultVector2( 0, 0 )
Setterset_min_window_size(value)
Getterget_min_window_size()

The minimum size of the window (without counting window manager decorations). Does not affect fullscreen mode. Set to (0, 0) to reset to the system default value.


Default0

Getteris_vsync_via_compositor_enabled()

If 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
Defaultfalse
Setterset_borderless_window(value)
Getterget_borderless_window()

If true, removes the window frame.

Note: Setting window_borderless to false disables per-pixel transparency.


  • bool window_fullscreen
Defaultfalse

Getteris_window_fullscreen()

If true, the window is fullscreen.


  • bool window_maximized
Defaultfalse
Setterset_window_maximized(value)

  • bool window_minimized
Defaultfalse
Setterset_window_minimized(value)
Getteris_window_minimized()

Defaultfalse
Setterset_window_per_pixel_transparency_enabled(value)
Getterget_window_per_pixel_transparency_enabled()

If true, the window background is transparent and window frame is removed.

Use get_tree().get_root().set_transparent_background(true) to disable main viewport background rendering.

Note: This property has no effect if Project > Project Settings > Display > Window > Per-pixel transparency > Allowed setting is disabled.

Note: This property is implemented on HTML5, Linux, macOS and Windows.

If true, the window is resizable by the user.


DefaultVector2( 0, 0 )
Setterset_window_size(value)
Getterget_window_size()

The size of the window (without counting window manager decorations).

Method Descriptions

Displays a modal dialog box using the host OS’ facilities. Execution is blocked until the dialog is closed.


  • bool can_draw ( ) const

Returns true if the host OS allows drawing.


  • bool can_use_threads ( ) const

Returns true if the current host platform is using multiple threads.


  • void center_window ( )

Centers the window on the screen if in windowed mode.


  • void close_midi_inputs ( )

Shuts down system MIDI driver.

Note: This method is implemented on Linux, macOS and Windows.


  • void delay_msec ( int msec ) const

Delay execution of the current thread by msec milliseconds.


  • void delay_usec ( int usec ) const

Delay execution of the current thread by usec microseconds.


  • void dump_memory_to_file ( String file )

Dumps the memory allocation ringlist to a file (only works in debug).

Entry format per line: “Address – Size – Description”.


  • void dump_resources_to_file ( String file )

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 OS.execute("ping", ["-w", "3", "godotengine.org"], false) will resolve to ping -w 3 godotengine.org in the system’s shell.

This method has slightly different behavior based on whether the blocking mode is enabled.

If 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.

If 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.

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 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)

Note: This method is implemented on Android, iOS, Linux, macOS and Windows.

Note: This method is implemented on Android, iOS, HTML5, Linux, macOS and Windows.


  • void show_virtual_keyboard ( String existing_text=”” )

Shows the virtual keyboard if the platform has one. The existing_text parameter is useful for implementing your own LineEdit, as it tells the virtual keyboard what text has already been typed (the virtual keyboard uses it for auto-correct and predictions).

Note: This method is implemented on Android, iOS and UWP.
