Folder Path Attribute

FolderPath is used on string properties, and provides an interface for directory paths.

// By default, FolderPath provides a path relative to the Unity project.
public string UnityProjectPath;

// It is possible to provide custom parent path. Parent paths can be relative to the Unity project, or absolute.
[FolderPath(ParentFolder = "Assets/Plugins/Sirenix")]
public string RelativeToParentPath;

// Using parent path, FolderPath can also provide a path relative to a resources folder.
[FolderPath(ParentFolder = "Assets/Resources")]
public string ResourcePath;

// By setting AbsolutePath to true, the FolderPath will provide an absolute path instead.
[FolderPath(AbsolutePath = true)]
public string AbsolutePath;

// FolderPath can also be configured to show an error, if the provided path is invalid.
[FolderPath(RequireExistingPath = true)]
public string ExistingPath;

// By default, FolderPath will enforce the use of forward slashes. It can also be configured to use backslashes instead.
[FolderPath(UseBackslashes = true)]
public string Backslashes;

// FolderPath also supports member references and attribute expressions with the $ symbol.
[FolderPath(ParentFolder = "$DynamicParent")]
[BoxGroup("Member referencing")]
public string DynamicFolderPath;

[BoxGroup("Member referencing")]
public string DynamicParent = "Assets/Plugins/Sirenix";

// FolderPath also supports lists and arrays.
[FolderPath(ParentFolder = "Assets/Plugins/Sirenix")]
public string[] ListOfFolders;
