Descripción

Does the asset form part of another asset?

Some assets may form part of another asset (for example, a procedural material can be part of a material package). This function tells if an asset is subordinated in this way.

using UnityEditor;
using UnityEngine;
public class Scriptable : ScriptableObject
{
}

public class AssetDatabaseExamples : MonoBehaviour
{
    [MenuItem("AssetDatabase/Is Sub Asset Example")]
    static void IsSubAssetExample()
    {
        var materialAsset = new Material(Shader.Find("Standard"));
        //materialAsset is still in memory, therefore this will be False
        Debug.Log(AssetDatabase.IsSubAsset(materialAsset));

        //Create a Scriptable object
        var scriptableAssetPath = "Assets/ScriptableObjects/NewObject.asset";
        var mainAsset = ScriptableObject.CreateInstance<Scriptable>();
        AssetDatabase.CreateAsset(mainAsset, scriptableAssetPath);

        //Add the Material Asset to the Scriptable object, so that the Material becomes a Sub Asset of the Scriptable object
        AssetDatabase.AddObjectToAsset(materialAsset, scriptableAssetPath);
        AssetDatabase.SaveAssets();

        //This will be True because the Material asset has been added to the mainAsset and is now a Sub Asset
        Debug.Log(AssetDatabase.IsSubAsset(materialAsset));
    }
}
