EditorUtility.IsPersistent

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

通常はプレハブ、テクスチャ、オーディオクリップ、アニメーションクリップ、マテリアルのようなアセットがディスクに保存されます。

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;
	}
}
