Considering that both children of the BlockExpEvent class (BlockBreakEvent and FurnaceExtractEvent) contain a method getPlayer() that returns the player responsible for triggering the event, I think it might be a good idea to include that method in the BlockExpEvent class so that if someone wants to cause something to occur regarding a player during either of the events, they don't need to set up two separate listeners to do the same thing. Specifically, in a plugin I am working on, I want the BlockExpEvent to change the dropped experience depending on certain attributes of the player responsible. I have to set up two separate listeners to do so, however, which seems unnecessary. I could be mistaken and this may be more complicated than I realize, but if so I'd love to know why. Thanks!
