InfoBoard help

Alright well I have made a few plugins but I have never looked into Scoreboards/InfoBoards, So can somebody show me a simple InfoBoard like with just for example the Objective Name "Test" with the amount of players online or something like that? or else point me towards a good tutorial?

Thanks!

 

Ok tutorial

Alright, first you want to create a ScoreboardManager varialbe then get the bukkit scoreboardmanager.
Then, create a Scoreboard variable and get a new scoreboard from your manager
Objective objective = board.registerNewObjective("test", "dummy");
Alright, now you've registerd your objective object and can cutozmiteit.
Set its display name by doing objective.setDisplaynaem("blah); You could set its display slot as well. As for the rest ,you could create a Score variable and I believe you can only display intergers (With custom display names) Read up on that tutorial

 

Creeoer So I did this (Not sure if right),

Code:java

package me.Immortal.ib;
 
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.plugin.java.JavaPlugin;
import org.bukkit.scoreboard.*;
 
 
public class Main extends JavaPlugin implements Listener {
 
ScoreboardManager manager = Bukkit.getScoreboardManager();
Scoreboard board = manager.getNewScoreboard();
Objective objective = board.registerNewObjective("test", "dummy");
 
public void onEnable() {
 
this.getServer().getPluginManager().registerEvents(this, this);
 
objective.setDisplaySlot(DisplaySlot.SIDEBAR);
objective.setDisplayName("Test");
 
}
@EventHandler
public void onPlayerJoin(PlayerJoinEvent e){
Player player= e.getPlayer();
 
Score score = objective.getScore(player.getDisplayName());
score.setScore(1);
player.setScoreboard(board);
}
}

But I get this error when joining,

Compile against the same version as you use on the server.
