Well i'd imagine you copied that from another base which is why you have all those errors. Half of those classes don't exist on your source so there is no "type" that exists. You would have to know what class is equivalent to PlayerHandler which is why I said "change it to what it's supposed to be". You didn't mention what base you're using so it's not like we can tell you what class to use. Maybe World.java if you have it? I'd imagine thats what it would be on ruse. World.getPlayers() otherwise I have no idea. Take a wild guess or use Eclipse and the search button and have at it
