Tutorial Scrolling scoreboards

Hey,

Did you ever want a scrolling scoreboard like mineplex?
Than this tutorial s perfect for you. I will teach you how to create your own scrolling scoreboard in only a few minutes:

First we need a scoreboard class:

Show Spoiler Hide Spoiler

PHP:


public class ScoreBoard {



}



Now we need a basic constructor:

Show Spoiler Hide Spoiler

PHP:


    private Player player;

    public ScoreBoard(Player player){
        this.player = player;
    }



Now we need to register thescoreboard:

Show Spoiler Hide Spoiler

PHP:


    private Player player;
    private Scoreboard scoreboard;
    private Objective test;
    private int scheduler;

    public ScoreBoard(Player player){
        this.player = player;
        this.scoreboard = Bukkit.getScoreboardManager().getNewScoreboard();
    
        this.test = scoreboard.registerNewObjective("test", "dummy");
        this.test.setDisplayName(ChatColor.DARK_RED + "" + ChatColor.BOLD + "TEST");
        this.test.setDisplaySlot(DisplaySlot.SIDEBAR);
    }



Now we add the class message:

Show Spoiler Hide Spoiler

PHP:


    public void scrollingMessage(String message, ChatColor color){
        scheduler = Bukkit.getScheduler().scheduleSyncRepeatingTask(MainClass.getInstance(), new Runnable() {
        
            int index = 0;
            String last = " " + message.substring(index, index + 16) + " ";
        
            @Override
            public void run() {
                if(player.getPlayer().isOnline()){
                    scoreboard.resetScores(color + last);
                
                    index++;
                
                    if(index + 16 >= message.length() + 1){
                        index = 0;
                    }
                
                    last = " " + message.substring(index, index + 16) + " ";
                    Score score = title.getScore(color + last);
                    score.setScore(7);
                    player.getPlayer().setScoreboard(scoreboard);
                }else{
                    Bukkit.getScheduler().cancelTask(scheduler);
                }
            }
        }, 20, 20);
    }



What this class does is it takes the string message and cuts it to a length of 16. Then it takes this string and displays it, by moving the delimiters of the string to one to the right each time. If the delimiters run out, the whole thing is reset to 0 and everything begins again.

MainClass.getInstance() is a link to your mainclass

Here's the whole class again:

Show Spoiler Hide Spoiler

PHP:


    private Player player;
    private Scoreboard scoreboard;
    private Objective test;
    private int scheduler;

    public ScoreBoard(Player player){
        this.player = player;
        this.scoreboard = Bukkit.getScoreboardManager().getNewScoreboard();
    
        this.test = scoreboard.registerNewObjective("test", "dummy");
        this.test.setDisplayName(ChatColor.DARK_RED + "" + ChatColor.BOLD + "TEST");
        this.test.setDisplaySlot(DisplaySlot.SIDEBAR);
    }

    public void scrollingMessage(String message, ChatColor color){
        scheduler = Bukkit.getScheduler().scheduleSyncRepeatingTask(MainClass.getInstance(), new Runnable() {
        
            int index = 0;
            String last = " " + message.substring(index, index + 16) + " ";
        
            @Override
            public void run() {
                if(player.getPlayer().isOnline()){
                    scoreboard.resetScores(color + last);
                
                    index++;
                
                    if(index + 16 >= message.length() + 1){
                        index = 0;
                    }
                
                    last = " " + message.substring(index, index + 16) + " ";
                    Score score = title.getScore(color + last);
                    score.setScore(7);
                    player.getPlayer().setScoreboard(scoreboard);
                }else{
                    Bukkit.getScheduler().cancelTask(scheduler);
                }
            }
        }, 20, 20);
    }



Now have fun with your new scrolling board by sending it to your player:

PHP:


ScoreBoard board = new ScoreBoard(player);
        board.scrollingMessage("Welcome " + player.getName(), ChatColor.GOLD);



Please report any bugs in the comment, I will try to keep this thread up to date.
If you're using this code crediting me would be awesome.

Have a happy new year and see you soon for more tutorials!!

 

@whereisthemonkey You might want to nullify that Player field once they log out. Also where the heck did the display() method come from?

 

@teej107 Yeah, I got my class with more stuff and there I got a display() function
And do you mean stopping the scheduler with nullfying the player?

 

I wouldn't call this a "Tutorial". You're just spoonfeeding the code without any explanation or even comments.
