something like AssetReferenceT<SceneAsset>

SceneAsset is in UnityEditor namespace.
how to reference a scene asset.

 

Scene is in the UnityEngine.SceneManagement namespace.

 

how to reference a scene asset. using AssetReferenceT

 

You can do something like this:

Code (CSharp):

1. public AssetReference someScene;

then just drag the addressable scene to the editor. It will accept the scene, though not sure if it is the same as using its key, as I haven't use

AssetReference

yet

 

AssetReference certainly could be use. it works, but i want to restrain the asset reference scene file only.
like AssetReferenceT<Sprite>

 

Do just that.

public class AssetReferenceScene : AssetReferenceT<Scene> { }

then use AssetReferenceScene for your field.

 

That doesn't work, AssetReferenceT requires a type of Object, Scene is a struct.

 

My workaround looks like this:

Code (CSharp):

1.   [System.Serializable]
2.   public class SceneAssetReference : AssetReference {
3.  
4.         public SceneAssetReference(string guid) : base(guid) {}
5.  
6.         //-----------------------------------------------------------------------------
7.  
8.         public override bool ValidateAsset(string path) {
9.             return path.EndsWith(".unity");
10.         }
11.     }

 

Here is a class with the same stuff as AssetReferenceT

Code (CSharp):

1. [System.Serializable]
2. public class AssetReferenceScene : AssetReference
3. {
4.     /// <summary>
5.     /// Construct a new AssetReference object.
6.     /// </summary>
7.     /// <param name="guid">The guid of the asset.</param>
8.     public AssetReferenceScene(string guid) : base(guid)
9.     {
10.     }
11.  
12.  
13.     /// <inheritdoc/>
14.     public override bool ValidateAsset(Object obj)
15.     {
16. #if UNITY_EDITOR
17.         var type = obj.GetType();
18.         return typeof(UnityEditor.SceneAsset).IsAssignableFrom(type);
19. #else
20.         return false;
21. #endif
22.  
23.     }
24.  
25.     /// <inheritdoc/>
26.     public override bool ValidateAsset(string path)
27.     {
28. #if UNITY_EDITOR
29.         var type = UnityEditor.AssetDatabase.GetMainAssetTypeAtPath(path);
30.         return typeof(UnityEditor.SceneAsset).IsAssignableFrom(type);
31. #else
32.         return false;
33. #endif
34.     }
35.  
36. #if UNITY_EDITOR
37.     /// <summary>
38.     /// Type-specific override of parent editorAsset.  Used by the editor to represent the asset referenced.
39.     /// </summary>
40.     public new UnityEditor.SceneAsset editorAsset => (UnityEditor.SceneAsset)base.editorAsset;
41. #endif
42. }

 

use SceneAsset

detail is in AssetReference filter

 

But SceneAsset lives in the UnityEditor namespace and cannot be used in builds. How does that work during runtime?
