pub struct OS { /* fields omitted */ }
Expand description

core singleton class OS inherits Object (unsafe).

Official documentation

See the documentation of this class in the Godot engine’s official documentation. The method descriptions are generated from it and typically contain code samples in GDScript, not Rust.

Class hierarchy

OS inherits methods from:

Safety

All types in the Godot API have “interior mutability” in Rust parlance. To enforce that the official thread-safety guidelines are followed, the typestate pattern is used in the Ref and TRef smart pointers, and the Instance API. The typestate Access in these types tracks whether the access is unique, shared, or exclusive to the current thread. For more information, see the type-level documentation on Ref.

Implementations

Constants

Returns a reference to the singleton instance.

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

Default Arguments

  • title - "Alert!"

Returns true if the host OS allows drawing.

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

Centers the window on the screen if in windowed mode.

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

Delay execution of the current thread by msec milliseconds.

Delay execution of the current thread by usec 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.

Sample code is GDScript unless otherwise noted.

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 [method 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.

Default Arguments

  • blocking - true
  • output - [ ]
  • read_stderr - false

Returns the scancode of the given string (e.g. “Escape”).

Returns the total number of available audio drivers.

Returns the audio driver name for the given index.

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

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

Sample code is GDScript unless otherwise noted.

Returns the command-line arguments passed to the engine. Command-line arguments can be written in any form, including both --key value and --key=value 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 editor/main_run_args in the Project Settings 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 --key=value form for arguments:

var arguments = {}
for argument in OS.get_cmdline_args():
    if argument.find("=") > -1:
        var key_value = argument.split("=")
        arguments[key_value[0].lstrip("--")] = key_value[1]

Returns the total amount of dynamic memory used (only works in debug).

Returns an environment variable.

Returns the path to the current engine executable.

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 [method SceneTree.quit] with an exit_code argument passed.

With this function you can get the list of dangerous permissions that have been granted to the Android application. Note: This method is implemented on Android.

Returns the IME cursor position (the currently-edited portion of the string) relative to the characters in the composition string.

If true, vertical synchronization (Vsync) is 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.

Returns true if the window should always be on top of other windows.

Returns true if the window is currently focused. Note: Only implemented on desktop platforms. On other platforms, it will always return true.

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

The current screen index (starting from 0).

The current tablet drvier in use.

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 [method SceneTree.quit] with an exit_code argument passed.

Sets the game’s icon using an Image resource. The same image is used for window caption, taskbar/dock and window selection dialog. Image is scaled as needed. Note: This method is implemented on HTML5, Linux, macOS and Windows.

Sets whether IME input mode should be enabled. If active IME handles key events before the application and creates an composition string and suggestion list. Application can retrieve the composition status by using [method get_ime_selection] and [method get_ime_text] functions. Completed composition string is committed when input is finished. Note: This method is implemented on Linux, macOS and Windows.

Sets position of IME suggestion list popup (in window coordinates). Note: This method is implemented on Linux, macOS and Windows.

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

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

  • OS.shell_open("mailto:example@example.com") opens the default email client with the “To” field set to example@example.com. See [url=https://blog.escapecreative.com/customizing-mailto-links/]Customizing mailto: Links[/url] for a list of fields that can be added. Use [method ProjectSettings.globalize_path] to convert a res:// or user:// path into a system path for use with this method. Note: This method is implemented on Android, iOS, HTML5, Linux, macOS and Windows.

Shows the virtual keyboard if the platform has one. The 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). The 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.

Default Arguments

  • existing_text - ""
  • multiline - false

Methods from Deref<Target = Object>

Adds a user-defined signal. Arguments are optional, but can be added as an [Array] of dictionaries, each containing name: String and type: int (see [enum Variant.Type]) entries.

Default Arguments

  • arguments - [ ]

Sample code is GDScript unless otherwise noted.

Calls the method on the object and returns the result. This method supports a variable number of arguments, so parameters are passed as a comma separated list. Example:

call("set", "position", Vector2(42.0, 0.0))

Note: In C#, the method name must be specified as snake_case if it is defined by a built-in Godot node. This doesn’t apply to user-defined methods where you should use the same convention as in the C# source (typically PascalCase).

Safety

This function bypasses Rust’s static type checks (aliasing, thread boundaries, calls to free(), …).

Sample code is GDScript unless otherwise noted.

Calls the method on the object during idle time. This method supports a variable number of arguments, so parameters are passed as a comma separated list. Example:

call_deferred("set", "position", Vector2(42.0, 0.0))

Note: In C#, the method name must be specified as snake_case if it is defined by a built-in Godot node. This doesn’t apply to user-defined methods where you should use the same convention as in the C# source (typically PascalCase).

Safety

This function bypasses Rust’s static type checks (aliasing, thread boundaries, calls to free(), …).

Sample code is GDScript unless otherwise noted.

Calls the method on the object and returns the result. Contrarily to [method call], this method does not support a variable number of arguments but expects all parameters to be via a single [Array].

callv("set", [ "position", Vector2(42.0, 0.0) ])

Safety

This function bypasses Rust’s static type checks (aliasing, thread boundaries, calls to free(), …).

Returns true if the object can translate strings. See [method set_message_translation] and [method tr].

Sample code is GDScript unless otherwise noted.

Connects a signal to a method on a target object. Pass optional binds to the call as an [Array] of parameters. These parameters will be passed to the method after any parameter used in the call to [method emit_signal]. Use flags to set deferred or one-shot connections. See [enum ConnectFlags] constants. A signal can only be connected once to a method. It will throw an error if already connected, unless the signal was connected with [constant CONNECT_REFERENCE_COUNTED]. To avoid this, first, use [method is_connected] to check for existing connections. If the target is destroyed in the game’s lifecycle, the connection will be lost. Examples:

connect("pressed", self, "_on_Button_pressed") # BaseButton signal
connect("text_entered", self, "_on_LineEdit_text_entered") # LineEdit signal
connect("hit", self, "_on_Player_hit", [ weapon_type, damage ]) # User-defined signal

An example of the relationship between binds passed to [method connect] and parameters used when calling [method emit_signal]:

connect("hit", self, "_on_Player_hit", [ weapon_type, damage ]) # weapon_type and damage are passed last
emit_signal("hit", "Dark lord", 5) # "Dark lord" and 5 are passed first
func _on_Player_hit(hit_by, level, weapon_type, damage):
    print("Hit by %s (lvl %d) with weapon %s for %d damage" % [hit_by, level, weapon_type, damage])

Default Arguments

  • binds - [ ]
  • flags - 0

Disconnects a signal from a method on the given target. If you try to disconnect a connection that does not exist, the method will throw an error. Use [method is_connected] to ensure that the connection exists.

Sample code is GDScript unless otherwise noted.

Emits the given signal. The signal must exist, so it should be a built-in signal of this class or one of its parent classes, or a user-defined signal. This method supports a variable number of arguments, so parameters are passed as a comma separated list. Example:

emit_signal("hit", weapon_type, damage)
emit_signal("game_over")

Returns the Variant value of the given property. If the property doesn’t exist, this will return null. Note: In C#, the property name must be specified as snake_case if it is defined by a built-in Godot node. This doesn’t apply to user-defined properties where you should use the same convention as in the C# source (typically PascalCase).

Returns the object’s class as a String.

Returns an [Array] of dictionaries with information about signals that are connected to the object. Each Dictionary contains three String entries:

  • source is a reference to the signal emitter.
  • signal_name is the name of the connected signal.
  • method_name is the name of the method to which the signal is connected.

Gets the object’s property indexed by the given NodePath. The node path should be relative to the current object and can use the colon character (:) to access nested properties. Examples: "position:x" or "material:next_pass:blend_mode".

Returns the object’s unique instance ID. This ID can be saved in EncodedObjectAsID, and can be used to retrieve the object instance with [method @GDScript.instance_from_id].

Returns the object’s metadata entry for the given name.

Returns the object’s metadata as a [PoolStringArray].

Returns the object’s methods and their signatures as an [Array].

Returns the object’s property list as an [Array] of dictionaries. Each property’s Dictionary contain at least name: String and type: int (see [enum Variant.Type]) entries. Optionally, it can also include hint: int (see [enum PropertyHint]), hint_string: String, and usage: int (see [enum PropertyUsageFlags]).

Returns the object’s Script instance, or null if none is assigned.

Returns an [Array] of connections for the given signal.

Returns the list of signals as an [Array] of dictionaries.

Returns true if a metadata entry is found with the given name.

Returns true if the object contains the given method.

Returns true if the given signal exists.

Returns true if the given user-defined signal exists. Only signals added using [method add_user_signal] are taken into account.

Returns true if signal emission blocking is enabled.

Returns true if the object inherits from the given class.

Returns true if a connection exists for a given signal, target, and method.

Returns true if the [method Node.queue_free] method was called for the object.

Send a given notification to the object, which will also trigger a call to the [method _notification] method of all classes that the object inherits from. If reversed is true, [method _notification] is called first on the object’s own class, and then up to its successive parent classes. If reversed is false, [method _notification] is called first on the highest ancestor (Object itself), and then down to its successive inheriting classes.

Default Arguments

  • reversed - false

Notify the editor that the property list has changed, so that editor plugins can take the new values into account. Does nothing on export builds.

Removes a given entry from the object’s metadata. See also [method set_meta].

Assigns a new value to the given property. If the property does not exist, nothing will happen. Note: In C#, the property name must be specified as snake_case if it is defined by a built-in Godot node. This doesn’t apply to user-defined properties where you should use the same convention as in the C# source (typically PascalCase).

If set to true, signal emission is blocked.

Assigns a new value to the given property, after the current frame’s physics step. This is equivalent to calling [method set] via [method call_deferred], i.e. call_deferred("set", property, value). Note: In C#, the property name must be specified as snake_case if it is defined by a built-in Godot node. This doesn’t apply to user-defined properties where you should use the same convention as in the C# source (typically PascalCase).

Sample code is GDScript unless otherwise noted.

Assigns a new value to the property identified by the NodePath. The node path should be relative to the current object and can use the colon character (:) to access nested properties. Example:

set_indexed("position", Vector2(42, 0))
set_indexed("position:y", -10)
print(position) # (42, -10)

Defines whether the object can translate strings (with calls to [method tr]). Enabled by default.

Adds, changes or removes a given entry in the object’s metadata. Metadata are serialized and can take any Variant value. To remove a given entry from the object’s metadata, use [method remove_meta]. Metadata is also removed if its value is set to null. This means you can also use set_meta("name", null) to remove metadata for "name".

Assigns a script to the object. Each object can have a single script assigned to it, which are used to extend its functionality. If the object already had a script, the previous script instance will be freed and its variables and state will be lost. The new script’s [method _init] method will be called.

Returns a String representing the object. If not overridden, defaults to "[ClassName:RID]". Override the method [method _to_string] to customize the String representation.

Translates a message using translation catalogs configured in the Project Settings. Only works if message translation is enabled (which it is by default), otherwise it returns the message unchanged. See [method set_message_translation].

The resulting type after dereferencing.

Dereferences the value.

Mutably dereferences the value.

The memory management kind of this type. This modifies the behavior of the Ref smart pointer. See its type-level documentation for more information. Read more

Creates an explicitly null reference of Self as a method argument. This makes type inference easier for the compiler compared to Option. Read more

Creates a new instance of Self using a zero-argument constructor, as a Unique reference. Read more

Performs a dynamic reference downcast to target type. Read more

Performs a static reference upcast to a supertype that is guaranteed to be valid. Read more

Creates a persistent reference to the same Godot object with shared thread access. Read more

Creates a persistent reference to the same Godot object with thread-local thread access. Read more

Creates a persistent reference to the same Godot object with unique access. Read more

Recovers a instance ID previously returned by Object::get_instance_id if the object is still alive. See also TRef::try_from_instance_id. Read more

Recovers a instance ID previously returned by Object::get_instance_id if the object is still alive, and panics otherwise. This does NOT guarantee that the resulting reference is safe to use. Read more
