IsSubAsset(Object)
Checks whether the asset is part of another asset.
public static bool IsSubAsset(Object obj)
Parameters
The asset object to query.
Returns
Type | Description |
|---|---|
| bool | True if the asset is part of another asset, otherwise false. |
Remarks
Some assets may form part of another asset (for example, a procedural material can be part of a material package). This method determines whether an asset is subordinated in this way.
Examples
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)); }}
IsSubAsset(EntityId)
Checks whether the asset is part of another asset.
public static bool IsSubAsset(EntityId entityId)
Parameters
The EntityID of the asset object to query.
Returns
Type | Description |
|---|---|
| bool | True if the asset is part of another asset, otherwise false. |

IsSubAsset(int)
