Best Way To Update A Scorebaord

Hello, I was wondering what's the best way to update the values on a scoreboard...

Here's an example of what I currently do;

Code:java

public class ScoreboardHandler {
 
private static HashMap<Player, IScoreboardHandler> playerScoreboards = new HashMap<>();
 
/**
* Creates the player's scoreboard and adds
* the player's scoreboard to the list of boards
* to be updated.
*/
public static void createScoreboard(final Player player) {
playerScoreboards.put(player, () -> {
 
Scoreboard scoreboard = Bukkit.getScoreboardManager().getNewScoreboard();
Objective objective = scoreboard.registerNewObjective("test", "dummy");
 
objective.setDisplaySlot(DisplaySlot.SIDEBAR);
objective.setDisplayName("title");
 
//... scores...
 
player.setScoreboard(scoreboard);
});
}
 
/**
* Begins the loop that updates the players
* scoreboards.
*/
public static void beginUpdating() {
Util.getScheduler().scheduleSyncRepeatingTask(Main.getInstance(), () -> {
for (Player online : Bukkit.getOnlinePlayers()) {
playerScoreboards.get(online).update();
}
}, 0, 20);
}
}
 
interface IScoreboardHandler {
 
/**
*
*/
public void update();
}

Please excuse any silly mistakes; I wrote it directly into the code insert thingy and it's 12:45am ;D

Could this cause a noticeable amount of lag since all of the players scorebaord's are getting updated every second even if they don't need to be? If it does - what's a better way to do it?

 

If you want to update it, all you really have to do is get the score and set it differently. Don't re-set the scoreboard to the player because that causes the scoreboard to flicker.
The way I did it:
https://github.com/kreashenz/xScore/blob/master/src/me/kreashenz/xscores/xScores.java#L84 probably not the best way but it works.

 

Also please don't abuse static :3
And the way I used to do it but sometimes in lagy conditions it flickers is to send player the scoreboard again so it overrides the one they currently had
