    File Reference

    Flax uses the concept of Asset which is a resource with type (typename), unique identifier (128-bit Guid) and data. This serves well for game resources such as textures, models, Visual Scripts, Json files but cannot be used for source files or other data files like text files, spreadsheets, etc.

    Here is an example usage of file reference which can be assigned in Editor to file from Content window. AssetReference attribute used on string property or field will store the path relative to the project root folder. You can specify the file extension to use (eg. .txt or .csv).

    public class MyFileReference : Script
    {
        [AssetReference(".txt"), CustomEditorAlias("FlaxEditor.CustomEditors.Editors.AssetRefEditor")]
        public string Path = "";
    
        /// <inheritdoc />
        public override void OnStart()
        {
            Debug.Log("Selected path: " + Path);
            // You can read file directly from disc (eg. via File.ReadAllText)
        }
    }
