    Is the UnityEvent type a delegate or class? I noticed that you subclass UnityEvent to create your own events. If it's not a delegate type, is it just a plain old class?

    Does the new UI use c# delegates/events at all, or does it completely bypass them?

    There are two sides to the UnityEvents, the serialization side (referencing the target and the method / arguments) and then the runtime invocation side. The serialization side is a class that holds all the data that needs to be remembered, the first time invoke is called on the UnityEvent we build this into a multicast delegate.

    So internally we do use delegates / events :)

    Can the source code of this be seen? As with the rest of the UI?
    I searched in the Bitbucket repo, but couldn't find it. Is this not part of the open-source ui, or did I just miss it somewhere?
