EditorUtility.IsPersistent

Description

Determines if an object is stored on disk.

Typically assets like prefabs, textures, audio clips, animation clips, materials are stored on disk.

Returns false if the object lives in the scene. Typically this is a game object or component but it could also be a material that was created from code and not stored in an asset but instead stored in the scene.

	// Tells if an Object is stored on disk or not.

	class PersistentInfo extends EditorWindow {

		@MenuItem("Examples/Object on Disk?")
		static function CheckPersistent() {
			var persistent : boolean = EditorUtility.IsPersistent(Selection.activeObject);
			Debug.Log(Selection.activeObject.name + ": " + persistent?"Stored on disk":"Not on disk");
		}

		@MenuItem("Examples/Object on Disk?", true)
		static function ValidateCheckPersistent() {
			return Selection.activeObject != null;
		}
	}
