Aight, I'll try it.

 

i have problems in the reset of a scoreboard...

Code:java

Objective inf_scoreboard = board.registerNewObjective("info", "dummy");
        inf_scoreboard.setDisplayName("Info");
        final Score jugadorescomenzar = inf_scoreboard.getScore(Bukkit.getOfflinePlayer(ChatColor.RED + "Jug. empezar:")); //Get a fake offline player
        jugadorescomenzar.setScore(contadorjugadores);

Now, i want to DELETE the score jugadorescomenzar, but i doesnt know how

 

Hi

I'm completely new to minecraft servers and Bukkit. Me and a couple of friends have bought a server on ClanForge Multiplay and we are using a Bukkit profile.

I've been trying to make a CTF arena but none of my scoreboards are showing up etc. So I've read through the thread and cant seem to find where I need to go to add scoreboards etc. On the ClanForge config files I only get the basic ones including server.properties. Do I need to do anything with that to show a scoreboard?

Any help would be more than grateful.

 

When I attempt to write "player.setScoreboard(hub);" into the script, I get an error with "player". Could you help me out?

 

I am getting error's. This is my code. I think i forgot something really stupid….

Code:java

package me.matthijs110.FactionsExtras;
 
import org.bukkit.Bukkit;
import org.bukkit.entity.Player;
import org.bukkit.event.Listener;
import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.scoreboard.Objective;
import org.bukkit.scoreboard.Scoreboard;
import org.bukkit.scoreboard.DisplaySlot;
import org.bukkit.scoreboard.ScoreboardManager;
 
public class Main extends JavaPlugin implements Listener {
 
    public void OnEnable(){
        getServer().getPluginManager().registerEvents(this, this);
 
        ScoreboardManager manager = Bukkit.getScoreboardManager();
        Scoreboard board = manager.getNewScoreboard();
        Objective objective = board.registerNewObjective("showhealth", "health");
        objective.setDisplaySlot(DisplaySlot.BELOW_NAME);
        objective.setDisplayName("/ 20");
 
        for(Player online : Bukkit.getOnlinePlayers()){
            online.setScoreboard(board);
            online.setHealth(online.getHealth());
        }
    }
} 

 

chasechocolate I don't understand why this code isn't working. I don't get any errors in when I load the plugin, however, the scoreboard never shows up.

TheRedHeadHD are you ever calling the register(player) method?

 

My scoreboard isn't working either..

Code:java

package me.matthijs110.FactionsExtras;
 
import org.bukkit.Bukkit;
import org.bukkit.entity.Player;
import org.bukkit.event.Listener;
import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.scoreboard.Objective;
import org.bukkit.scoreboard.Scoreboard;
import org.bukkit.scoreboard.DisplaySlot;
import org.bukkit.scoreboard.ScoreboardManager;
 
public class Main extends JavaPlugin implements Listener {
 
public void OnEnable(){
getServer().getPluginManager().registerEvents(this, this);
 
ScoreboardManager manager = Bukkit.getScoreboardManager();
Scoreboard board = manager.getNewScoreboard();
Objective objective = board.registerNewObjective("showhealth", "health");
objective.setDisplaySlot(DisplaySlot.BELOW_NAME);
objective.setDisplayName("/ 20");
 
for(Player online : Bukkit.getOnlinePlayers()){
online.setScoreboard(board);
online.setHealth(online.getHealth());
}
}
} 

 

Why are you setting the player's health to the player's health? You need to update their scoreboard value, not set their health..

 

How

 

Well it will update whenever they take damage I'd assume. You could set the score to their health once to update it initially...but setting their health to their health isn't going to do anything...

 

I've got a question about updating the scoreboard.
I tried updating the scoreboard every 2 ticks, due to a timer I want to use.
The scoreboard is specific to the player and will update for EVERY player.
It works just fine, the problem is that it keeps flickering, when I change the delay to 100 ticks it just works fine.
My question is: Is there a minumum delay you can use to refresh a scoreboard, if so, what is this delay?

The following is my code.. (where 'timer(player)' is the time that is passed since the start of the timer)
I've also showed the scoreboard to the player in a onPlayerJoin event

Code:java

    public void run() {
        for(Player player : Bukkit.getOnlinePlayers()) {
 
            ScoreboardManager manager = Bukkit.getScoreboardManager();
            org.bukkit.scoreboard.Scoreboard board = manager.getMainScoreboard();
 
            float dtime = 0;
 
            if(timer(player.getName()) != null){
                dtime = (float) timer(player.getName()) / 10;
            }
 
            String p = player.getName();
 
            OfflinePlayer time = Bukkit.getOfflinePlayer("§9§lTime");
            OfflinePlayer timev = Bukkit.getOfflinePlayer("§b"+dtime);
            OfflinePlayer name = Bukkit.getOfflinePlayer("§a"+p);
 
            Objective objective = null;
 
            if(board.getObjective(p) == null){
                objective = board.registerNewObjective(p, "dummy");
            }else{
                objective = board.getObjective(p);
            }
 
            objective.setDisplaySlot(DisplaySlot.SIDEBAR);
 
            for(OfflinePlayer ofpl : board.getPlayers()){
                board.resetScores(ofpl);
            }
 
            objective.setDisplayName("§6Stats");
 
            if(plugin.speedRunTime.get(player.getName()) != null){
                objective.getScore(time).setScore(2);
                objective.getScore(timev).setScore(1);
            }else{
                board.resetScores(time);
                board.resetScores(timev);
            }
 
            objective.getScore(name).setScore(3);

 

chasechocolate I don't understand why this is not working.

 

TheRedHeadHD is "onlineplayers" equal to 0?

 

chasechocolate
Yes it is.

 

One issue here, is that I have never heard of a program called "Miencraft".

 

Ultimate_n00b I fixed that issue, but yet again, the scoreboard doesn't show up. Does it have to do with Optifine?

 

TheRedHeadHD I think the score won't show up if it is 0. Try changing it to 1

 

TheRedHeadHD, I think you will have to make a scheduled repeating that runs every sec or two, because when you run the server there are no players online and scoreboard will get assigned to noone; Or you could do this code in player join event

 

chasechocolate Where am i supposed to put these lines cause when i put them were i think i do it gives me a null pointer exception

Code:java

    ScoreboardManager manager = Bukkit.getScoreboardManager();
    Scoreboard board = manager.getNewScoreboard();
 
    Objective objective = board.registerNewObjective("coins", "dummy");
    Score score = objective.getScore(Bukkit.getOfflinePlayer(ChatColor.GREEN + "Coins:"));

How can I separate? Every player should have his own rank. Currently there's always displayed the rank of one player :/.

And also how do I get rid of the 0 before [Rank] ? There's always one in front of the []..

Code:java

 public void onEnable() {
ScoreboardManager manager = Bukkit.getScoreboardManager();
Scoreboard board = manager.getMainScoreboard();
 
Objective objective = board.registerNewObjective("Flawssentials", "Achievement.THE_END");
objective.setDisplaySlot(DisplaySlot.BELOW_NAME);
 
final Scoreboard finalBoard = board;
final Objective finalObjective = objective;
 
 
Bukkit.getScheduler().scheduleSyncRepeatingTask(this, new Runnable() {
@Override
public void run() {
for (Player online : Bukkit.getOnlinePlayers()) {
 
String color = "GRAY";
String rank = getRank(online.getName());
 
if (getMorale(online.getName()) >= 1000) {
color = "AQUA";
} else if (getMorale(online.getName()) <= -1000) {
color = "DARK_RED";
}
finalObjective.setDisplayName("[" + ChatColor.valueOf(color) + rank + ChatColor.WHITE + "]");
online.setScoreboard(finalBoard);
getLogger().info("Scoreboards gesetzt");
}
}
 
 
}, 0L, 60*20L);
}

 

FlawlezZ the 0 is always there, it represents an unset score.

 

Ok, What is The Solution for Q1?can you answer please

 

Codisimus I set it to 1. It still doesn't work.

 

TheRedHeadHD

 

Sorry but I have no idea wut you're talking about and I couldn't find my previous post lol.

Hello Chase,
I have used your tutorial on how to make a scoreboard plugin and most of it was helpful. Except, When I register a new objective and i try to set the display slot and name there are errors and it will not work. If you know what is wrong please tell me. Thanks!
Here is my main class so far:

Code:

package me.pieman.board;
 
import org.bukkit.Bukkit;
import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.scoreboard.Objective;
import org.bukkit.scoreboard.Scoreboard;
import org.bukkit.scoreboard.ScoreboardManager;
 
 
public class Board extends JavaPlugin{
   
    ScoreboardManager sbManager = Bukkit.getScoreboardManager();
    Scoreboard Kills = sbManager.getNewScoreboard();
   
    Objective obj = Kills.registerNewObjective("Kills", "playerKillCount");
    obj.getDisplaySlot(DisplaySlot.SIDEBAR);
    obj.getDisplayName(ChatColor.GREEN + "Kills");

The obj.getDisplayName/getDisplaySlot will not work they show errors.

 

You can't run code outside of a method..

 

Is it possible to display a mob's health under their name or is it only for players?
