    Yes exactly, I would like to be able to add whatever formatting I want without having a mandatory score for my objective, so basically only showing the display name.
    What I don't like about scores is that I didn't find a way to add some text after the score, which means that you'll always get a number at the end of your sidebar, even though you don't want it.
    I'm wondering if there could be a way to bypass this.

    What if instead of just 1 variable(Kills) We wanted 2?(Kills + Deaths).
    I am talking about this
    [​IMG]
    How can we add under kills, 1 more or even more variables?

    Simply add a new score:
    Code:java
    1. Score scoreKills = objective.getScore(Bukkit.getOfflinePlayer(ChatColor.GREEN + "Kills:"));
    2. Score scoreDeaths = objective.getScore(Bukkit.getOfflinePlayer(ChatColor.GREEN + "Deaths:"));
    3.  
    4. scoreKills.setScore(1);
    5. scoreDeaths.setScore(3);

    How can I show the same scoreboard to different Players? So they all have different things in the Scoreboard.

    Player 1:

    Statistics:
    Level: 1
    Money: 100

    Player 2:

    Statistics:
    Level: 10
    Money: 20

    Sorry for my Bad English

    Edit: I haven't found a way to store the scoreboards in Hashmaps. I know how to store them but its no different if i use the Saved Scoreboard or the not saved one. Because If I modify the scoreboard with this name It will modify the saved Scoreboard too...

    Please I need your Help! Thanks!

    etaxi341 like you mentioned, create a HashMap<String, Scoreboard> and save player scoreboards in there:
    Code:java
    1. HashMap<String, Scoreboard> playerScoreboards = new HashMap<String, Scoreboard>();
    2.  
    3. //Creating a new scoreboard for a player
    4. Scoreboard board = manager.getNewScoreboard();
    5. //Register objectives and scores
    6.  
    7. player.setScoreboard(board);
    8. playerScoreboards.put(player.getName(), board);

    And then I would create an update() method to change the player's stats.

    Rockslide a bug possibly? It works fine for me.

    Thank you! I got it working by using this code (Coded by me)
    Code:java
    1. public static HashMap<String, Scoreboard> UsedScoreboard = new HashMap<String, Scoreboard>();
    2. public static HashMap<String, Score> levelscore = new HashMap<String, Score>();
    3. public static HashMap<String, Score> moneyscore = new HashMap<String, Score>();
    4.  
    5. public static void create(Player p, String BoardName, String BoardDisplayName){
    6. ScoreboardManager manager = Bukkit.getScoreboardManager();
    7. Scoreboard board = manager.getNewScoreboard();
    8.  
    9. Objective objective = board.registerNewObjective(BoardName, "dummy");
    10.  
    11. objective.setDisplaySlot(DisplaySlot.SIDEBAR);
    12. objective.setDisplayName(BoardDisplayName);
    13.  
    14. Score level = objective.getScore(Bukkit.getOfflinePlayer(ChatColor.GREEN + "Level" + ChatColor.GRAY + ":"));
    15. Score money = objective.getScore(Bukkit.getOfflinePlayer(ChatColor.GREEN + "Money" + ChatColor.GRAY + ":"));
    16.  
    17. level.setScore(0);
    18. money.setScore(0);
    19.  
    20. levelscore.put(p.getName(), level);
    21. moneyscore.put(p.getName(), money);
    22.  
    23. UsedScoreboard.put(p.getName(), board);
    24. }
    25.  
    26. public static void update(Player p){
    27.  
    28. Score level = levelscore.get(p.getName());
    29. Score money = moneyscore.get(p.getName());
    30.  
    31. level.setScore(PlayerDataListener.getLevel(p.getName()));
    32. money.setScore(PlayerDataListener.getMoney(p));
    33.  
    34. }
    35.  
    36. public static void set(Player p){
    37.  
    38. p.setScoreboard(UsedScoreboard.get(p.getName()));
    39.  
    40. }

    Hi, I've got a problem with the sidebar scoreboard. I've probably missed something but it appears grayed out and barely visible. Anyone else had this problem?
    [​IMG]

    I don't use any fancy code:
    Code:
    // When player goes into a state where they should have info displayed:
    ply.sboard = Bukkit.getScoreboardManager().getNewScoreboard();
     
    Objective sobjective = ply.sboard.registerNewObjective("status", "dummy");
    sobjective.setDisplayName(ChatColor.GREEN+ply.getName()+":");
    sobjective.setDisplaySlot(DisplaySlot.SIDEBAR);
     
    updatePlayerScore(ply);
    pl.setScoreboard(ply.sboard);
     
     
    // updatePlayerScore:
    updatePlayerScore(PlayerDescriptor ply) {
        Objective sobjective = ply.sboard.getObjective("status");
        sobjective.getScore(Bukkit.getOfflinePlayer(ChatColor.YELLOW+"Punkty: ")).setScore(ply.ranking);
        sobjective.getScore(Bukkit.getOfflinePlayer(ChatColor.YELLOW+"PieniÄ…dze: ")).setScore(ply.cash/100);
    }
    EDIT: Sorry, it was a fault of MinecraftIM client mod, after disabling it everything works fine :)

    How would I update the scoreboard without having to create a new scoreboard for it to update. Like I have timer with and it will basically countdown,but my scoreboard won't update and I also want it to update whenever a player join. Creating a new scoreboard all the time makes it look really nasty(I am really picky about things :p. and every time I set a new scoreboard it removes the current scoreboard and it looks like it is flashing if I do it every second)

    Look at my Post above. I made an Update Method so you just need to trigger the scoreboard creating once if a player joins and then about every seconds / 20 Ticks you use the update() method by me

    kreashenz
    On scoreboard create you could save this data in an hashmap so you can check if the hashmap already contains this player or not. If not you could create the scoreboard for this Player

    Do you have a method that will update the displayname of the scoreboard as well becuase I forgot to mention my time is in my header of the scoreboard and your method works wonders :)

    etaxi341

    You just need to rename the objective like this:

    The first time when you create the Scoreboard you need to use this
    Code:java
    1. Objective objective = board.registerNewObjective(BoardName, "dummy");
    2. objective.setDisplayName("StartDisplayName");


    And to update the name every Second you need this
    Code:java
    1. objective.setDisplayName("NewDisplayName");


    I haven't tested it but i think it should work like this.

    timtower I think it's a bug. It should be possible to do this because it is possible with CommandBlocks. But I haven't found a way to use 2 Scoreboards at once too!

    This code dont work for me!
    Code:java
    1. ScoreboardManager manager = Bukkit.getScoreboardManager();
    2. Scoreboard board = manager.getNewScoreboard();
    3.  
    4. Objective objective = board.registerNewObjective("showhealth", "health");
    5. objective.setDisplaySlot(DisplaySlot.BELOW_NAME);
    6. objective.setDisplayName("/ 20");
    7.  
    8. for(Player online : Bukkit.getOnlinePlayers()){
    9. online.setScoreboard(board);
    10. online.setHealth(online.getHealth()); //Update their health
    11. }


    Or i paste it in an event? How it works to use that

    Hey, do you know how I can fix this? When there are 2 players online it will only update the time for one of the players
    Code:java
    1. public void updateTime() {
    2. plugin.staskID = plugin.getServer().getScheduler().scheduleSyncRepeatingTask(plugin, new Runnable(){
    3. public void run(){
    4. objective.setDisplayName(GameMOTD.motdPrefix + ChatColor.GOLD + " Time: " + GameTimer.formattedTime());
    5. }
    6. }, 20, 20);
    7. }

    Where do you call this Method? If Its in the onEnable() you should update it for everyone like this:
    Code:java
    1. for (Player p : Bukkit.getServer().getOnlinePlayers(){
    2. updateTime();
    3. set(p);
    4. }


    The set(p) method is from my post at page 8. I think it should work like this.

    Or if this won't work could you tell me where you created the objective ? because you use objective.setDisplay...
    You need to set the DisplayName of the Scoreboard for the right Person because if you use my Methods at Page 8 you need to save the Objective in a Hashmap.

    I think I found your Problem. You need to save the scoreboard in a Hashmap too because if you won't do this you will only update the score of the last joined player. And there is another thing. When you create a Scoreboard you gave the Scoreboard a Name and a DisplayName. The Name can only exist once. So the best way is to call the scoreboard like the PlayerName and just let the DisplayName of The Scoreboard the same in every Scoreboard.

    Here is what you need to Change:

    First you need to add at the top of your Method Class a new Hashmap:
    Code:java
    1. public static HashMap<String, Scoreboard> playerScoreboards = new HashMap<String, Scoreboard>
    2. ();
    3. public static HashMap<String, Objective> playerObjectives = new HashMap<String, Objective>();


    Then you need to modify your create Method like this:
    Code:java
    1. public void createScoreboard(Player p) {
    2.  
    3. if (!playerScoreboards.containsKey(p.getName())){
    4.  
    5. manager = Bukkit.getScoreboardManager();
    6.  
    7. board = manager.getNewScoreboard();
    8.  
    9. objective = board.registerNewObjective(p.getName(), "dummy");
    10.  
    11. objective.setDisplaySlot(DisplaySlot.SIDEBAR);
    12.  
    13. objective.setDisplayName(GameMOTD.motdPrefix + ChatColor.GOLD + " Time: " + GameTimer.formattedTime());
    14.  
    15.  
    16.  
    17. Score score = objective.getScore(Bukkit.getOfflinePlayer(ChatColor.GREEN + "Kills:"));
    18.  
    19. score.setScore(0);
    20.  
    21.  
    22.  
    23. plugin.kills.put(p.getName(), 0);
    24.  
    25. killscore.put(p.getName(), score);
    26.  
    27.  
    28.  
    29. Score score2 = objective.getScore(Bukkit.getOfflinePlayer(ChatColor.GREEN + "Alive:"));
    30.  
    31. score2.setScore(plugin.gplayers.size());
    32.  
    33.  
    34.  
    35. alivescore.put(p.getName(), score2);
    36.  
    37.  
    38.  
    39. Score score3 = objective.getScore(Bukkit.getOfflinePlayer(ChatColor.GREEN + "Spectators:"));
    40.  
    41. score3.setScore(plugin.spectators.size());
    42.  
    43. specscore.put(p.getName(), score3);
    44.  
    45. playerScoreboards.put(p.getName(), board);
    46. playerObjectives.put(p.getName(), objective);
    47. }
    48. }


    Then you need to add a new Method called set(Player p)
    Code:java
    1. public static void set(Player p){
    2.  
    3. p.setScoreboard(playerScoreboards.get(p.getName()));
    4.  
    5. }


    on Player Join you need to call first the createScoreboard Method and then the set Method.

    Then you need to modify the UpdateTime Method a little bit. Like this:
    Code:java
    1. public void updateTime(Player p) {
    2. plugin.staskID = plugin.getServer().getScheduler().scheduleSyncRepeatingTask(plugin, new Runnable(){
    3. public void run(){
    4. objective = playerObjectives.get(p.getName());
    5. objective.setDisplayName(GameMOTD.motdPrefix + ChatColor.GOLD + " Time: " + GameTimer.formattedTime());
    6. }
    7. }, 20, 20);
    8. }

    Is there a way for it to check for a player that has ten kills?
     
  30. is there a way to display different "scores for different people?"
    like a villager will see "villager" under everyones name except for a mayor which would have "Mayor" under it and a bandit can see "bandit" under bandits, "villager" under villager and "mayor" under mayors?
