How do you implement your own listenable in Verse?

Hello,
you can’t initialize a listenable interface inside a class.
For now, I recommend exposing an event like the CountdownEndedEvent (for example OnTimerIteration/OnTick) that lets users of the class Await it. You’d then Signal the event when needed.

I haven’t played around with it much, but maybe something like this could also be helpful to you:

# In this case the functions we accept should take one string parameter and return void.
my_fun := type{_(:string):void}

my_subscribable := class:
    var Funs<private>:[]my_fun = array{}
    
    Subscribe<public>(Fun:my_fun):void =
        set Funs += array{Fun}
    
    Dispatch<private>():void =
        for (Fun:Funs):
            Fun("Hello")
