AssetReference by Component Type

Hey, is there already a solution for using an AssetReference bound to a Component type?
I want to be able to reference an AddressableAsset by a Component and only show those Components in the AssetReference popup.

I've come up with this which seems to work ok. Just wondering if something else already exists?

Code (CSharp):

1. [Serializable]
2. public class AssetReferenceCustomComponent : AssetReferenceComponent<CustomComponent> {
3.  
4.     public AssetReferenceCustomComponent(string guid) : base(guid) {
5.     }
6. }
7.  
8. public abstract class AssetReferenceComponent<TComponent> : AssetReferenceT<TComponent> {
9.  
10.     public AssetReferenceComponent(string guid) : base(guid) {
11.     }
12.  
13.     public override bool ValidateAsset(Object obj) {
14.  
15.         var type = obj.GetType();
16.  
17.         if (typeof(TComponent).IsAssignableFrom(type)) {
18.  
19.             return true;
20.         }
21.  
22.         GameObject gameObject = (obj as GameObject);
23.  
24.         return gameObject ? gameObject.GetComponent<TComponent>() != null : false;
25.     }
26.  
27.     public override bool ValidateAsset(string path) {
28.  
29. #if UNITY_EDITOR
30.         var type = UnityEditor.AssetDatabase.GetMainAssetTypeAtPath(path);
31.  
32.         if (typeof(TComponent).IsAssignableFrom(type)) {
33.  
34.             return true;
35.         }
36.  
37.         GameObject gameObject = UnityEditor.AssetDatabase.LoadAssetAtPath<GameObject>(path);
38.  
39.         return gameObject ? gameObject.GetComponent<TComponent>() != null : false;
40. #else
41.         return false;
42. #endif
43.     }
44. }

 

We actually added it to the samples repo about 2 weeks ago, but haven't publicized it yet because it isn't finished. There's some clean up we're mostly done with that should be up this week.

@unity_bill, will ComponentReference functionality come to the Addressables package?
