Solved Scoreboard Help

For some reason my scoreboard not working and it's not displaying.
Main Class:

Code:java

public void onEnable()
{
HealthScoreboard();
}
 
public void HealthScoreboard(){
ScoreboardManager manager = Bukkit.getScoreboardManager();
Scoreboard board = manager.getNewScoreboard();
score = board.registerNewObjective("Score", "dummy");
health = board.registerNewObjective("Health", "dummy");
headHealth = board.registerNewObjective("Headhealth", "dummy");
score.setDisplaySlot(DisplaySlot.SIDEBAR);
health.setDisplaySlot(DisplaySlot.PLAYER_LIST);
headHealth.setDisplaySlot(DisplaySlot.BELOW_NAME);
headHealth.setDisplayName("/ 20");
 
for(Player online : Bukkit.getOnlinePlayers()){
online.setScoreboard(board);
online.setHealth(online.getHealth()); //Update their health
}
}

Join Listener:

Code:java

package me.LordVakar.UHC.Listeners;
 
import me.LordVakar.UHC.UHC;
 
import org.bukkit.Bukkit;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerJoinEvent;
import org.bukkit.scoreboard.Score;
import org.bukkit.scoreboard.Scoreboard;
import org.bukkit.scoreboard.ScoreboardManager;
 
public class Join implements Listener
{
UHC main;
 
@EventHandler
public void onPlayerJoin(PlayerJoinEvent e)
{
Player p = e.getPlayer();
ScoreboardManager manager = Bukkit.getScoreboardManager();
Scoreboard board = manager.getNewScoreboard();
p.setScoreboard(board);
//Score settingScore1 = main.headHealth.getScore(p);
//Score settingScore2 = main.health.getScore(p);
//settingScore1.setScore(20);
//settingScore2.setScore(20);
main.updateHealth(p);
 
for(Player online : Bukkit.getOnlinePlayers()){
online.setScoreboard(board);
online.setHealth(online.getHealth()); //Update their health
main.updateHealth(online);
}
}
}
 

and yes I did register my event.

 

Do you get any error in the console? Any stacktraces?

I never saw a stacktrace until today:

I'm not sure, but maybe you cannot set a scoreboard to a player if the board has no objective.

 

AoH_Ruthless

There is an objective?

 

LordVakar
The objective you register when making a new scoreboard...

 

AoH_Ruthless
Look at the OP?

1. score = board.registerNewObjective("Score", "dummy");
2. health = board.registerNewObjective("Health", "dummy");
3. headHealth = board.registerNewObjective("Headhealth", "dummy");

 

LordVakar
You didnt do any of that in your playerjoinevent.

 

So are you saying I should register it in my playerjoinevent instead?
Okay, I'll try it.

I found the error, it apparently fires the joinevent when you are still connecting.
How do you schedule it so it fires a few ticks after?
I'm not good at schedulers and ticks.

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

 

PHP:

Bukkit.getServer().getScheduler().scheduleSyncDelayedTask(this, new Runnable(){
  public void run(){
    //Here your code.
  }
}, 20L); //20 ticks = 1 second

 

HungerCraftNL
I thought it'd work but the stacktrace says it cannot pass player join event to MoaUHC

Code:text

 
@EventHandler
public void onPlayerJoin(PlayerJoinEvent event) {
Bukkit.getServer().getScheduler().runTaskLater((Plugin) this, new Runnable(){
public void run(){
for (Player player : pl.getServer().getOnlinePlayers()) {
player.setScoreboard(pl.scoreboard);
}
}
}, 40L);
}
}

This is how I register my events:

Code:java

public void onEnable()
{
pl = this;
registerEvents(this, new Join()
);
}
public static void registerEvents(org.bukkit.plugin.Plugin plugin, Listener... listeners) {
for (Listener listener : listeners) {
Bukkit.getServer().getPluginManager().registerEvents(listener, plugin);
}
}

Any help?

 

This is how I register the events in my main class:

PHP:

Bukkit.getServer().getPluginManager().registerEvents(this, this);

and in another class:

PHP:

Anotherclass ac = new Anotherclass();
Bukkit.getServer().getPluginManager().registerEvents(this.ac, this);

 

HungerCraftNL
That makes no difference?
I actually have a method to register my event.
I always get the stacktrace:

Bukkit.getServer().getScheduler().runTaskLater((Plugin)this, newRunnable(){
The this is not your main class (the class that extends JavaPlugin)

 

Yes I know that...? It makes no difference. Even with your way, it gives a stacktrace. All my other events and listeners work with my method.

 

Does your main class contains 'extends JavaPlugin'?

 

HungerCraftNL

Of course it does.
Otherwise all the features in the plugin would be broken.
And yes, I do have a plugin.yml too.

 

LordVakar
Change the this argument at the scheduler too the class that extends JavaPlugin.

 

HungerCraftNL
Omg, thank you!
Yer my savior, I couldn't move on with my coding until now
