public static bool Contains(int instanceID);

Description

Is object an asset?

Returns true when an object is an asset (corresponds to a file in the Assets folder), and false if it is not (for example object in the Scene, or an object created at runtime).

using UnityEditor;
using UnityEngine;

public class AssetDatabaseExamples : MonoBehaviour { [MenuItem("AssetDatabase/Contains Example")] static void ContainsExample() { //Material is created in memory and the Asset Database does not know about it var material = new Material(Shader.Find("Specular")); Debug.Log(AssetDatabase.Contains(material)); //Output will be false //Material is then saved to disk as an asset and therefore Asset Database knows that it exists AssetDatabase.CreateAsset(material, "Assets/Materials/MyMaterial.mat"); Debug.Log(AssetDatabase.Contains(material)); //Output will be true } }
