C# newb-- delegates?

So we downloaded one of Prime 31's plugins, and at first I thought "man, I totally would have done this differently"-- until I realized that he was doing something better than what I would have done.


I noticed he uses delegates and events, and it appears as though you can just add a function to an event.

Are the addition and subtraction operators overloaded to mean "AddEventListener" and "RemoveEventListener" for the event class?

Also, while I understand what a delegate is and to some degree how they work, I've never seen that delegate keyword in front of a function in the languages I've worked in. Does anyone mind explaining how it works?

 

And for bonus points, can I use the + and - operators on the event class in java script ;-)

 

I earned my own bonus points, yes you can

 

How? I was under the impression that events were not usable in "JavaScript".

You'd be wise to check out Prime31's videos, especially if you're using the plugins.

I'm unsure if you can define an event in JavaScript, but if one's defined in a C# script then it's usable no problem.
