Question by Weberekt · Nov 20, 2016 at 01:40 PM · c#unity 5

Serializable class definition in base class doesn't show in editor

 Generic.cs
 public class Generic<T> : MonoBehaviour  {
 
     public GenericEvent OnGenericEvent;
 
     [Serializable]
     public class GenericEvent : UnityEvent<T> {
     }
 }
 
 MyClass.cs
 public class MyClass : Generic<MyOtherClass> {
 }
 

OnGenericEvent doesn't show in Editor, is this a bug?

Unity is not able to serialize generic classes. You need to define a concrete type for T when deriving from it.

Okay, thanks. I'll have to find other ways then

I got it working. Editor is able to serialise generic classes, but it has to be inside the class not base class.

 public class GenericTrigger<T> : $$anonymous$$onoBehaviour  {
 
     public abstract class GenericTriggerEvent : UnityEvent<T> {
     }
 }
 
 public class $$anonymous$$yTrigger : GenericTrigger<Class> {
 
     public $$anonymous$$yEvent Event;
 
     [Serializable]
     public class $$anonymous$$yEvent : GenericTriggerEvent {
     }
 }

Hi @Weberekt,

Isn't it [System.Serializable] rather than just [Serializable] ?

Cheers.

I have "using System;" at top. I didn't include all coding
