On that note, there is a non-dynamic delegate declared using DECLARE_MULTICAST_DELEGATE.
That declares a class of type TMulticastDelegate<void, …>. This void returning delegate has an AddLambda function. However, sadly, this type of event is not visible to blueprints… if you mark such a delegate with an UPROPERTY, the UHT complains that you must specify a UCLASS, USTRUCT or UENUM.
I’m just trying to find a way of exposing an event to both blueprints and C++ AND be able to use lambdas on it. One way to do it would be to declare two events: one dynamic multicast and one just multicast; then, the code just calls both events whenever it’s triggered. However that solution leaves me quite unsatisfied…
