    Hello everyone.

    I have had so many problems with scoreboard. I thought I fixed them all but I just noticed this:

    Code:

    @sgavster In Line 70 in your Scoreboard class is a NullPointerException. Either the oldO variable or the value you set it to is null.

    @I Al Istannen That's the thing.. Nothing should be null.. I don't see how oldO is null. It works usually (but it doesn't work when you join at first, and after that, I don't know why..) but after relog it doesn't work..

    @sgavster Maybe check if the sameboard.getObjective("Quadular...") is null. Or debug the code and add System#out#println() after you retrieve a new Variable and check when the error strikes. Maybe the scoreboard gets cleared if the user disconnects?

    @sgavster Probably because you set sameBoard to p.getScoreboard(). So if this isnt null it can't have no players. What i wanted to try was not adding a !null check, at least not now, but getting what is null. So you could just make a System.out.println for every thing you want to use, like System.out.println(sameBoard.getObjective("QuadularMC")) And this for all vars that can be null. this way you get exactly which var is null.

    @I Al Istannen The objective isn't null -- It's now the name.. I even did this (for debug, as you said)
    Bukkit.broadcastMessage(sameBoard.getPlayers().toString());
    and it throws me this error:
    [​IMG]
    Actually; I'm stupid.
    Bukkit.broadcastMessage(Boolean.toString(sameBoard.getObjective("QuadularMC") == null));
    returns true..

    @sgavsteThen loop through sameBoard.getObjectives() and return every objective and the size of the collection. Then you can see if your registeres object was registered.

    @I Al Istannen Now it says
    QuadularMC
    1
    false
    for(Objective o : sameBoard.getObjectives()) {
    Bukkit.broadcastMessage(o.getName());
    Bukkit.broadcastMessage(Integer.toString(sameBoard.getObjectives().size()));
    }
    the false is saying the the
    Bukkit.broadcastMessage(Boolean.toString(oldO == null) + " " + Boolean.toString(sameBoard == null));
    but I still get Name cannot be blank error

    @sgavster Where do you get the error? What are you trying to do with the scoreboard?

    @sgavster I changed the code to this:
    Code:
    

   public static void setNewBoard(Player p) {

     if (sameBoard == null) {

       Scoreboard b = man.getNewScoreboard();
       Objective o = b.registerNewObjective("QuadularMC", "dummy");
       o.setDisplaySlot(DisplaySlot.SIDEBAR);

       Score votes = o.getScore("Kills");
       votes.setScore(1);

       Score votez = o.getScore("§bVotes:");
       votez.setScore(2);

       Score blank = o.getScore(" ");
       blank.setScore(3);

       Score deaths = o.getScore("Deaths");
       deaths.setScore(4);

       Score deathz = o.getScore("§bDeaths:");
       deathz.setScore(5);

       p.setScoreboard(b);

       sameBoard = p.getScoreboard();

     }
   }

   @SuppressWarnings("deprecation")
   public static void updateBoard(Player p) {
     if (p.getScoreboard() == null) {
       setNewBoard(p);
     } else {
       sameBoard = p.getScoreboard();

       if (sameBoard != null) {

         Objective oldO = sameBoard.getObjective(DisplaySlot.SIDEBAR);
         if (oldO == null
             && sameBoard.getObjective("QuadularMC") == null) {
           oldO = sameBoard
               .registerNewObjective("QuadularMC", "dummy");
         }

         if (sameBoard.getObjective("QuadularMC") != null
             && sameBoard != null && sameBoard.getPlayers() != null) {
           for (OfflinePlayer players : sameBoard.getPlayers()) {
             sameBoard.resetScores(players.getName());
           }
         }

         oldO.setDisplayName("QuadularMC");
         Score votes = oldO.getScore("Kills");
         votes.setScore(1);

         Score votez = oldO.getScore("§bVotes:");
         votez.setScore(2);

         Score deaths = oldO.getScore("Deaths");
         deaths.setScore(3);

         Score deathz = oldO.getScore("§bDeaths:");
         deathz.setScore(4);

         p.setScoreboard(sameBoard);
         oldO.setDisplaySlot(DisplaySlot.SIDEBAR);
       }
     }
   }

   @EventHandler
   public void onJoin(PlayerJoinEvent e) {
     Player p = e.getPlayer();
     if (sameBoard == null) {
       setNewBoard(p);
     } else {
       updateBoard(p);
     }
   }
    removing everything which isn't included in the Listener class, because i just don't have the code to include it.
    And it works like a charm.

    @I Al Istannen I tried that -- thanks btw

    The same thing happens though, when I try to update it (for example, my SettingsMenu) using this:

    ScoreBoard.updateBoard(p);

    I get the Name cannot be blank error :(

    I think it means the scoreboard names..
    This error occurs whenever I turn scoreboard off, then on
    also, I need to add the check config part, to turn it on and off, any suggestions (you removed it from the code, I'm not sure where it should be)

    @sgavster On which line occurs the Error? And whats the content of that line?

    EDIT:
    Okay, I looked into your LoginHandler class and afaik you should not return a Key at getThings(), but a configurationSection: http://wiki.bukkit.org/Configuration_API_Reference
    What you do now returns a key but not the vote,death,... .You would need to do it with .getConfig() or return an ConfigurationSection which has all the Keys and values you need inside.

    @sgavster You should use sameBoard.getEntries(), the other one is deprecated.
    https://hub.spigotmc.org/javadocs/bukkit/
    I can't see where this could throw an IllegalArgumentException :confused:

    EDIT: I tried hard... however i cant reproduce your error! Everthing works fine

    @I Al Istannen That fixed the name, but now I get an NPE on this line:
    oldO.setDisplayName(MSG.quadularmc);
    (MSG.quadularmc is NOT null!)

    @sgavster then oldO must be null. Maybe you don't have anything in your sidebar?

    EDIT: In your if which checks if oldO is null it just gets set to sameBoard if the objective "QUadularMC" in sameBoard is also null. This doesn't havr to be the case.

    I clear the sidebar, like this:
    p.getScoreboard().clearSlot(DisplaySlot.SIDEBAR);
    when I disable my setting.. Is there a better way to not display it?

    @sgavster Have you read my edit? You set your sidebar to null. Then you set oldO to sidebar ==> oldO = null. In your next if oldO = null, but sameBoard.getObjective... isnt null ==> no fixing of oldO = null. Then you call oldO.setDisplayName() ==> NPE.
    At least i think so ;)

    @I Al Istannen I'm a little confused now.
    Is there an easy way to just remove the scoreboard when the player wants it gone, then add it when they dont want it gone?

    @sgavster Deleting the scoreboard the way you did is ok. But when you call updateBoard again... Then you get the thing i described. Just change
    Code:
    if (oldO == null && sameBoard.getObjective("QuadularMC") == null) {
  oldO = sameBoard.registerNewObjective("QuadularMC", "dummy");
}

//TO

if (oldO == null || sameBoard.getObjective("QuadularMC") == null) { //notice the ||
  oldO = sameBoard.registerNewObjective("QuadularMC", "dummy");
}
    in your updateBoard method.

    @I Al Istannen Now it says "An objective of name 'QuadularMC' already exists' On the oldO = sameBoard.registerNewObjective("QuadularMC", "dummy");

    @sgavster Well then
    Code:
    if (oldO == null) { 
  if(sameBoard.getObjective("QuadularMC") == null)
    oldO = sameBoard.registerNewObjective("QuadularMC", "dummy");
  else {
    oldO = sameBoard.getObjective("QuadularMC");
}

    @I Al Istannen I can not thank you enough! Thank you SO MUCH! It works. I have not tested it when a second player has joined, but if it doesn't work I'll say something.. Again, thank you SO MUCH!

    @sgavster I hadn't got any experience with Scoreboards either, so I apologize for not perfect solutions :) Let's hope I won't hear anything from you xD
