So... I've never made an XP farm from a mob spawner, and I'd like to make a really efficient one. Can anyone with experience in this point me to a YouTube tutorial or explain a good way to do it? I'm not sure what the spawn code is like for mob spawners, so I'm not sure I'd be able to make a very good one.
Well, it depends on what type of spawner you are making, ie cave spider spawner, zombie spawner, or just plain dark room, etc.
