I'm trying to use an ObservableCollection in a ScriptableObject, but it doesn't generate any serialized field in the asset editor.

Here is my code:

[CreateAssetMenu(fileName = "Dictionnary.Asset", menuName = "dictionnary")]
public class TADictionnary : ScriptableObject
    public ObservableCollection<TAVerb> verbs;
[CreateAssetMenu(fileName = "Verb.Asset", menuName = "verb")]
public class TAVerb : ScriptableObject
    public List<string> synonyms;
    public string keyword;

I've read it used to not work on older unity version, but I'm using LTS 2022.3. So I'm not sure why it doesn't work.

  • \$\begingroup\$ Did you read anything saying this should work in version 2022? I don't recall seeing serialization of ObservableCollections in any of the update notes in Unity's version log. This related Q&A on StackOverflow shows how to implement your own version that serializes correctly for Inspector display. If you're using another source for your ObservableCollection, be sure to specify/link it in your question. \$\endgroup\$

  • \$\begingroup\$ And is there a specific reason you need to use a ObservableCollection and not any of the other Collections available? \$\endgroup\$

  • \$\begingroup\$ @DMGregory, I've seen that post, but I prefer to use native classes instead of implementing custom ones. But if I don't have any other options, I will implement that solution. \$\endgroup\$
