Util ScoreboardManager - Sidebar handling made easier!

  1. Hello everyone, a while back I made a small Scoreboard utility that gives everyone a unique sidebar to show their stats on while staying on the same scoreboard.

    How does it work?
    When enabled, ScoreboardManager registers a new bukkit Scoreboard instance and saves it in a field. Using custom packet handling ScoreboardManager shows different sidebar scores for everyone while having the players use the same Scoreboard. Using this library, you don't have to register each team for the scoreboard of every player online, saving you a bit of memory when a lot of players are online and lots of teams are modified.

    Usage
    Put Scoreboard.java from below somewhere in your package. You can access the ScoreboardManager class by calling Scoreboard.getManager(). There are 3 things you need to do to get the scoreboard up and running:
    1. When your plugin enables, call ScoreboardManager#start() to setup the scoreboard
    2. When a player joins, call ScoreboardManager#setupBoard(player) to give the player a scoreboard instance
    3. By calling ScoreboardManager#getScoreboard(player) you get a Scoreboard instance of the player, where you can edit stuff. When a player quits call Scoreboard#unregister() so it gets removed from the memory.
    To modify a player's sidebar, there are a couple of methods:
    • setScores(List<String>) OR setScores(String[] scores)
      • Sets a player's scores to the specified scores, it will show up in descending order
    • setHeader(String)
      • Set a player's header (the sidebar's displayname on top)
    • update()
      • Call this when you are done with modifying the stuff and are ready to show the updates to the player. If the new scores are the same size of the old scores, the method changes only the score names that have changed, to prevent flickering.
    Source Code
    For the util to work, you need to create a class called Scoreboard, and put this code in:
    http://pastebin.com/tbaxsq8F

    Example

    Show Spoiler
    Code:
    @EventHandler
    public void onPlayerJoin(PlayerJoinEvent event) {
      Player p = event.getPlayer();
      final Scoreboard board = Scoreboard.getManager().setupBoard(p);
      board.setHeader(ChatColor.GOLD + p.getName()).update();
      new BukkitRunnable() {
        int time = 4;
        @Override
        public void run() {
          time--;
          String[] scores;
          if(time == 0) {
            cancel();
            scores = {ChatColor.RED + "Welcome to the server!"};
          } else {
            scores = {ChatColor.GRAY + "Counting down...", ChatColor.GREEN + "  " + time};
          }
          board.setScores(scores).update();
        }
      }.runTaskTimer(<main plugin>, 5L, 20L);
    }


    Notes
    • On player join you might need to put a little delay on join before setting the scores for them to show up.
    • Should be compitable with most versions, if not report the stacktrace.

    Good but can you write an example with List<> and put a screenshot?

  3. How do you remove a player's scoreboard? I haven't implemented this into my plugin but I'd like to, but my plugin has arenas and only players in arenas have scoreboards along with nametags.

    @megamichiel Are you even following this post...? -_-

    Oh sorry, I don't always have time. You can enable the scoreboard by calling ScoreboardManager#setupBoard(player), and disable it by calling unregister() on the player's scoreboard. That should do what you want.
    @Krumb069
    List<String> isn't so hard to do. You can just create an arraylist, add some elements to it and call setScores(list)
    I'll post some screenshots
     
  5. Thanks =) I was just wondering because I see you helping around on the forums a lot, so I found it a bit weird not to reply to this thread...

    I tried to make it version compitable, but not all classes have the same name. Does it throw any errors in console?

    I see what's wrong. I think you made some changes in your code because the stacktrace doesn't match the place. In your run() method you're detecting if the frame is equal to the frames size, and after that increasing the frame. But if the frame is 1 below the size it doesn't set the frame to 0 and still increases so it throws an IndexOutOfBoundsException. put the frame++; line before you check if the frame is equal to the frames size, that should fix it.

    @megamichiel
    thx bro gonna test now. tell me how can i add a blank line?
     
  16. @DeathZonePT
    You can create blank lines by placing simply a chatcolor in the line, e.g.:
    Code:
    board.setScores(Arrays.asList("Line", "§a", "Another line", "§b"));
    Note that you can't have identical scores, I will make a workaround for it soon

    You can create scores below a player's name by going to Scoreboard.getManager().getScoreboard(). This returns the bukkit version of the scoreboard. From there you can create a new objective, and set the display slot to below name.

    Hey can you help me here. How can disable the scoreboard in a specific world like if the player is in the work the scoreboard will work but if they go to a minigames the scoreboard will disable!
     
  25. @DeathZonePT
    You can either:
    1. Set their scores to an empty list/array
    2. Call unregister() on their scoreboard (make sure you call ScoreboardManager#setupBoard(player) when you want to enable it again.

    Code:
    //Listen for when a player changes world
    public void onWorldChanged(PlayerChangedWorldEvent event) {
      Player p = event.getPlayer();
      Scoreboard board = Scoreboard.getManager().getScoreboard(p);
      if(event.getPlayer().getWorld().getName().equals("someWorldName")) { //Check if the player went to a certain world
        board.setScores(new String[0]).update(); //Set their scores to an empty array and update
      } else { //Set their scores to some totally random ones
        board.setScores(new String[] {"One!", "Two!", "Three!"}).update();
      }
    }
