Question Timeline custom signal, the receiver still needs 'normal' signal receiver attached too

I've set up a custom signal, with an emitter and a receiver and it works just fine to pass a string.
However the endpoint receiving object not only requires the custom receiver (as expected) but also needs the default Signal Receiver on it which doesn't even get 'used' as it can't work with custom data.
However, without the latter the timeline loses it's reference to the target object.

My emitter inherits from SignalEmitter and my receiver from MonoBehaviour, INotificationReceiver

Code (CSharp):

1. public class ParameterizedEmitter<T> : SignalEmitter
2. {
3.     public T parameter;
4. }
5.  
6. public class SignalEmitterWithString : ParameterizedEmitter<string> { }
7.  
8.  
9. public class SignalReceiverWithString : MonoBehaviour, INotificationReceiver
10. {
11.     public SignalAssetEventPair[] signalAssetEventPairs;
12.  
13.     [Serializable]
14.     public class SignalAssetEventPair
15.     {
16.         public SignalAsset signalAsset;
17.         public ParameterizedEvent events;
18.  
19.         [Serializable]
20.         public class ParameterizedEvent : UnityEvent<string> { }
21.     }
22.  
23.     public void OnNotify(Playable origin, INotification notification, object context)
24.     {
25.         if (notification is ParameterizedEmitter<string> stringEmitter)
26.         {
27.             var matches = signalAssetEventPairs.Where(x => ReferenceEquals(x.signalAsset, stringEmitter.asset));
28.             foreach (var m in matches)
29.             {
30.                 m.events.Invoke(stringEmitter.parameter);
31.             }
32.         }
33.     }
34. }

What am I missing?

 

Code (CSharp):

1.     [TrackClipType(typeof(SignalReceiverWithString ))]
2.     [TrackBindingType(typeof(SignalReceiverWithString ))]
3.     public class SignalReceiverWithString : TrackAsset {}

This seems to add it to the track and works with the binding.

 

So dump inheriting from MonoBehaviour, INotificationReceiver? Just that even the official examples use those?

 

Oops my bad! Should be a new class

Code (CSharp):

1. [TrackClipType(typeof(SignalReceiverWithString ))]
2.     [TrackBindingType(typeof(SignalReceiverWithString ))]
3.     public class SignalReceiverWithStringTrack : TrackAsset {}

 

Ok, what happens with this new class? Unity will just automatically use it when creating a new track of the 'WithString' types?

 

Yeah - Unity seems to pick up any extension of the TrackAsset as an option for a new track. You can bind the matching type to the track then.

 

Thanks. I'll try this out.
