Just wondering, is there a way to use a dummy scoreboard and get the stats from a criteria scoreboard?(Show a dummy scoreboard, but be able to get each players stats if I were to use the criteria)

 

chasechocolate I don't understand something. In your first example you set the display name " /20", and you don't even use a .getHealth method. Wouldn't it just set there object name (or in your case under the name) to " /20"?

 

JPG2000 nope. I set the objective type to "health", and Minecraft will automatically set the score to the player's health.

 

How can i do that the scoreboard will only show in the world "cw"

 

chasechocolate
In the tutorial you should add how to save the Scoreboard if they have stats like Kills so it doesn't reset every time a person logs in.

 

PieMan456 that's more along the lines of a MySQL or flatfile tutorial, but I may later.

How can I get players in a list and create a score for each one of them so that others people can see how much score each one of the players have? I'm really having trouble with this. This is what I have right now:

Code:java

if(onArena1LobbyList.size() == 4){
for(Player targetPlayer : Bukkit.getOnlinePlayers()){
if(onArena1LobbyList.contains(targetPlayer.getName())){
targetPlayer.sendMessage(ChatColor.GOLD + "The game will be starting soon...");
for(String playerList : onArena1LobbyList){
Player players = Bukkit.getServer().getPlayer(playerList);
ScoreboardManager boardManager = Bukkit.getScoreboardManager();
Scoreboard gameStats = boardManager.getNewScoreboard();
Objective objective = gameStats.registerNewObjective("gameStats", "dummy");
objective.setDisplaySlot(DisplaySlot.SIDEBAR);
objective.setDisplayName(ChatColor.WHITE + "Game Stats (Lives)");
Score playerIScore = objective.getScore(Bukkit.getOfflinePlayer(players.getDisplayName() + ": " ));
playerIScore.setScore(5);
Score playerIIScore = objective.getScore(Bukkit.getOfflinePlayer(players.getDisplayName() + ": " ));
playerIIScore.setScore(5);
Score playerIIIScore = objective.getScore(Bukkit.getOfflinePlayer(players.getDisplayName() + ": " ));
playerIIIScore.setScore(5);
Score playerIVScore = objective.getScore(Bukkit.getOfflinePlayer(players.getDisplayName() + ": " ));
playerIVScore.setScore(5);
targetPlayer.setScoreboard(gameStats);
}
}
}

Yes, I do realise that this code is really messed up right now. I've asked many people and each of them are giving me different answers and is confusing me. Please reply ASAP.

P.S. Don't mind the spacing errors, it's just the input messing up.

 

How to do multiple lines in DisplaySlot.SIDEBAR?
example:

You can simply just create new scores for each of the lines.

 

chasechocolate I dont know why but I am getting errors with this http://gyazo.com/201c310419d763d45c1ea66ecc0c0cce

Change your variable 'objective' to 'obj'. (That's how you've registered it.)

 

SourceForums Nope. (I tried changing the name to see if it works forgot to change it back)

 

MyNameIsHariK

Code:java

ScoreboardManager manager = Bukkit.getScoreboardManager;
Scoreboard board = mamager.getNewScoreboard;
Objective ocjective = board.registierNewObjective("lives", "totalKillCount");
ovjective.setDisplaySlot(DisplaySlot.SIDEBAR);
objective.setDisplayName("Kills");

 

SourceForums Stilll..... http://gyazo.com/0e104cf51942e0dfa10b3a4450ecdabc

What does it say when you click your mouse on them? Does it show the error?

 

Thank you

 

Hi guys, I have been coding this plugin for a server and i want a scoreboard on it. It all works fine exept when i first start the server i get a massive error but after a reload it works fine how do i fix this as i need the plugin to work on a server which can't reload.

if u need to see the code i can provide it

Whats is wrong with this code??

Code:java

ScoreboardManager manager = Bukkit.getScoreboardManager();
Scoreboard board = this.manager.getNewScoreboard();
Objective obj = board.registerNewObjective("test", "dummy");
Score rock = obj.getScore(Bukkit.getOfflinePlayer(ChatColor.DARK_GRAY + "Rock Gym"));
Score water = obj.getScore(Bukkit.getOfflinePlayer(ChatColor.BLUE + "Water Gym"));
Score electric = obj.getScore(Bukkit.getOfflinePlayer(ChatColor.YELLOW + "Electric Gym"));
Score grass = obj.getScore(Bukkit.getOfflinePlayer(ChatColor.GREEN + "Grass Gym"));
Score poison = obj.getScore(Bukkit.getOfflinePlayer(ChatColor.DARK_PURPLE + "Poison Gym"));
Score psychic = obj.getScore(Bukkit.getOfflinePlayer(ChatColor.LIGHT_PURPLE + "Psychic Gym"));
Score fire = obj.getScore(Bukkit.getOfflinePlayer(ChatColor.DARK_RED + "Fire Gym"));
Score ground = obj.getScore(Bukkit.getOfflinePlayer(ChatColor.GRAY + "Ground Gym"));
 
public void onEnable(){
getConfig().options().copyDefaults(true);
saveConfig();
 
getServer().getPluginManager().registerEvents(this, this);
 
obj.setDisplayName(ChatColor.GREEN + "Open Gyms");
obj.setDisplaySlot(DisplaySlot.SIDEBAR);
 
}
public void onDisable(){
 
}
@EventHandler
public void onJoin (PlayerJoinEvent e){
Player p = e.getPlayer();
p.setScoreboard(board);

This is what is is saying in the console on the first start up. but if i reload it is fine.

p.s line 48 is:

1. Scoreboard board = this.manager.getNewScoreboard();

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

Move the creation of all your variables inside the onEnable method.
For example:

Code:

Score fire;
public void onEnable() {
fire = ....
}

 

tried it and it still does the same thing

 

How can i change color of setScore() value?

 

As far as I know, you cannot.

 

Whenver I use this code, it always sets the score under the other players names, and not (p).

Anyone know why?

Code:

        Player p = (Player) event.getPlayer();
        Scoreboard b = p.getScoreboard();
        Objective obj = b.registerNewObjective("aaa", "dummy");
        obj.setDisplaySlot(DisplaySlot.BELOW_NAME);
        obj.setDisplayName("ggg");
        Score bob = obj.getScore(p);
        bob.setScore(3);
        p.setScoreboard(b);

 

Acer_Mortem, In which event do you use it?

 

spoljo666

Close-inventory.

 

I can't seem to get this to work, when I have the scoreboard code in the main class (in the onEnable method), and I can't modify it from other classes/methods.

 

Yes, you cannot access local variables globally.

 

Hi! I am having trouble with my plugin and I dont know what is wrong with it because it could not be loaded Please help me!

here is my scoreboard:

Code:java

 
public class Board{
private Ninjutsu p ;
public void init(){
while(true){
try {
Thread.sleep(1000);
for (Player player : Bukkit.getOnlinePlayers()){
updateScoreboard(player);
}
}catch(Exception ignored){
}
}
}
public void updateScoreboard(Player player){
Scoreboard board = Bukkit.getScoreboardManager().getNewScoreboard();
Objective obj = board.registerNewObjective("Info", "dummy");
obj.setDisplaySlot(DisplaySlot.SIDEBAR);
 
obj.setDisplayName(ChatColor.BLUE + "=====" + ChatColor.AQUA + "Info" + ChatColor.BLUE + "=====");
Score score = obj.getScore(Bukkit.getOfflinePlayer("" + ChatColor.RED + "Chakra"));
 
score.setScore(p.getConfig().getInt("player." + player.getName()));
player.setScoreboard(board);
}
}
 

And here is my main class:

Code:java

 
public class Ninjutsu extends JavaPlugin{
public Board scoreBoard = new Board();
 
@Override
public void onEnable(){
getLogger().info("Ninjutsu is enabled!");
init();
}
 
@Override
public void onDisable(){
getLogger().info("Ninjutsu is disabled!");
saveConfig();
}
void init(){
scoreBoard.init();
getServer().getPluginManager().registerEvents(new PlayerJoin(), this);
}
}
 

 

chasechocolate How would you check if a player has a scoreboard or the scoreboard is registered?

 

DreTaX player.getScoreboard()?
