Expand description

core class Directory inherits Reference (reference-counted).

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.

Memory management

The lifetime of this object is automatically managed through reference counting.

Class hierarchy

Directory 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 Ownership in these types tracks whether ownership is unique, shared, or exclusive to the current thread. For more information, see the type-level documentation on Ref.

Implementations

Creates a new instance of this object.

This is a reference-counted type. The returned object is automatically managed by Ref.

Changes the currently opened directory to the one passed as an argument. The argument can be relative to the current directory (e.g. newdir or ../newdir), or an absolute path (e.g. /tmp/newdir or res://somedir/newdir). Returns one of the Error code constants (OK on success).

Copies the from file to the to destination. Both arguments should be paths to files, either relative or absolute. If the destination file exists and is not access-protected, it will be overwritten. Returns one of the Error code constants (OK on success).

Returns whether the current item processed with the last get_next call is a directory (. and .. are considered directories).

Returns whether the target directory exists. The argument can be relative to the current directory, or an absolute path.

Returns whether the target file exists. The argument can be relative to the current directory, or an absolute path.

Returns the absolute path to the currently opened directory (e.g. res://folder or C:\tmp\folder).

Returns the currently opened directory’s drive index. See get_drive to convert returned index to the name of the drive.

On Windows, returns the name of the drive (partition) passed as an argument (e.g. C:). On other platforms, or if the requested drive does not exist, the method returns an empty String.

On Windows, returns the number of drives (partitions) mounted on the current filesystem. On other platforms, the method returns 0.

Returns the next element (file or directory) in the current directory (including . and .., unless skip_navigational was given to list_dir_begin). The name of the file or directory is returned (and not its full path). Once the stream has been fully processed, the method returns an empty String and closes the stream automatically (i.e. list_dir_end would not be mandatory in such a case).

On UNIX desktop systems, returns the available space on the current directory’s disk. On other platforms, this information is not available and the method returns 0 or -1.

Initializes the stream used to list all files and directories using the get_next function, closing the currently opened stream if needed. Once the stream has been processed, it should typically be closed with list_dir_end. If skip_navigational is true, . and .. are filtered out. If skip_hidden is true, hidden files are filtered out.

Default Arguments
  • skip_navigational - false
  • skip_hidden - false

Closes the current stream opened with list_dir_begin (whether it has been fully processed with get_next does not matter).

Creates a directory. The argument can be relative to the current directory, or an absolute path. The target directory should be placed in an already existing directory (to create the full path recursively, see make_dir_recursive). Returns one of the Error code constants (OK on success).

Creates a target directory and all necessary intermediate directories in its path, by calling make_dir recursively. The argument can be relative to the current directory, or an absolute path. Returns one of the Error code constants (OK on success).

Opens an existing directory of the filesystem. The path argument can be within the project tree (res://folder), the user directory (user://folder) or an absolute path of the user filesystem (e.g. /tmp/folder or C:\tmp\folder). Returns one of the Error code constants (OK on success).

Deletes the target file or an empty directory. The argument can be relative to the current directory, or an absolute path. If the target directory is not empty, the operation will fail. Returns one of the Error code constants (OK on success).

Renames (move) the from file or directory to the to destination. Both arguments should be paths to files or directories, either relative or absolute. If the destination file or directory exists and is not access-protected, it will be overwritten. Returns one of the Error code constants (OK on success).

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 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 set_message_translation and 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 emit_signal. Use flags to set deferred or one-shot connections. See 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 CONNECT_REFERENCE_COUNTED. To avoid this, first, use 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 connect and parameters used when calling 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 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. See also is_class. Note: get_class does not take class_name declarations into account. If the object has a class_name defined, the base class name will be returned instead.

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 [PropertyHint][PropertyHint]), hint_string: String, and usage: int (see [PropertyUsageFlags][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 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. See also get_class. Note: is_class does not take class_name declarations into account. If the object has a class_name defined, is_class will return false for that name.

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

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

Send a given notification to the object, which will also trigger a call to the [_notification][Self::_notification] method of all classes that the object inherits from. If reversed is true, [_notification][Self::_notification] is called first on the object’s own class, and then up to its successive parent classes. If reversed is false, [_notification][Self::_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 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 set via 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 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 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 [_init][Self::_init] method will be called.

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