Question by Vunpac · Nov 21, 2015 at 08:25 PM · interfaceevents

Interface event parameters

I have recently been digging into Interfaces, and Event systems. I feel I have a fair understanding of both to a degree.

I know an interface is a solution around single inheritance. I can implement them fine. My question is. How does Unity pass information to their interfaces (for example IPointerClickHandler)? You add the interface, then create the proper matching function as with any interface. But then it just works. Where as any I create I have to have an array or something that gathers all the objects then calls the function passing the arguments in.

I assume they have something to do with events. But even when I am using an event manager I must subscribe / unsubscribe any methods I create. So how is it Unity passes the event information to all objects using their interfaces?
