DirAccess¶

Inherits: RefCounted < Object

Provides methods for managing directories and their content.

描述¶

This class is used to manage directories and their content, even outside of the project folder.

DirAccess can't be instantiated directly. Instead it is created with a static method that takes a path for which it will be opened.

Most of the methods have a static alternative that can be used without creating a DirAccess. Static methods only support absolute paths (including res:// and user://).

# Standard
var dir = DirAccess.open("user://levels")
dir.make_dir("world1")
# Static
DirAccess.make_dir_absolute("user://levels/world1")

Note: Many resources types are imported (e.g. textures or sound files), and their source asset will not be included in the exported game, as only the imported version is used. Use ResourceLoader to access imported resources.

Here is an example on how to iterate through the files of a directory:

func dir_contents(path):
    var dir = DirAccess.open(path)
    if dir:
        dir.list_dir_begin()
        var file_name = dir.get_next()
        while file_name != "":
            if dir.current_is_dir():
                print("Found directory: " + file_name)
            else:
                print("Found file: " + file_name)
            file_name = dir.get_next()
    else:
        print("An error occurred when trying to access the path.")

public void DirContents(string path)
{
    using var dir = DirAccess.Open(path);
    if (dir != null)
    {
        dir.ListDirBegin();
        string fileName = dir.GetNext();
        while (fileName != "")
        {
            if (dir.CurrentIsDir())
            {
                GD.Print($"Found directory: {fileName}");
            }
            else
            {
                GD.Print($"Found file: {fileName}");
            }
            fileName = dir.GetNext();
        }
    }
    else
    {
        GD.Print("An error occurred when trying to access the path.");
    }
}

Property Descriptions¶

bool include_hidden

void set_include_hidden ( bool value )
bool get_include_hidden ( )

If true, hidden files are included when navigating the directory.

Affects list_dir_begin, get_directories and get_files.

bool include_navigational

void set_include_navigational ( bool value )
bool get_include_navigational ( )

If true, . and .. are included when navigating the directory.

Affects list_dir_begin and get_directories.

Method Descriptions¶

Error change_dir ( String to_dir )

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 (@GlobalScope.OK on success).

Error copy ( String from, String to, int chmod_flags=-1 )

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.

If chmod_flags is different than -1, the Unix permissions for the destination path will be set to the provided value, if available on the current operating system.

Returns one of the Error code constants (@GlobalScope.OK on success).
