public static bool IsPersistent (Object target);

説明

オブジェクトがディスク上に保存されているかを確認します

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.

using UnityEditor;
using UnityEngine;

// Tells if an Object is stored on disk or not. public class PersistentInfo : EditorWindow { [MenuItem("Examples/Object on Disk?")] static void CheckPersistent() { bool persistent = EditorUtility.IsPersistent(Selection.activeObject); Debug.Log(Selection.activeObject.name + ": " + (persistent ? "Stored on disk" : "Not on disk")); }

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