Basically in my code I want to enable pvp when a certain block is placed. I have the code set up with the listener and what not. Here is my code as is right now for the class I am trying to do this in: http://pastebin.com/GjwUyjSZ any help would be very much appreciated! Thanks in advance Update on code. Specified diamond block as type and what happens when the player places it. I just want the code that will enable pvp for that world. http://pastebin.com/CfHxsvvw New update, trying to require you to be in the world "TheSearch" for it to work. I also want it to broadcast the message in the code to the players in that world. Again Thanks in advance ! http://pastebin.com/fb6PjiB1 EDIT by Moderator: merged posts, please use the edit button instead of double posting.
