Scrolling Objective

Using this code here,

Code:

static ScoreboardManager manager;
    static Scoreboard scoreboard;
    static Objective objective;
   
    @Override
    public void onEnable(){
        manager = Bukkit.getScoreboardManager();
        scoreboard = manager.getNewScoreboard();
        objective = scoreboard.registerNewObjective("Sideboard", "dummy");
 
        objective.setDisplayName("Testing");
        objective.setDisplaySlot(DisplaySlot.SIDEBAR);
       
        Bukkit.getScheduler().scheduleSyncRepeatingTask(this, new Runnable(){
            public void run(){
               
                Score test = objective.getScore(Bukkit.getOfflinePlayer(ChatColor.GOLD + "" + ChatColor.BOLD + "^ plz"));
                test.setScore(0);
               
                Scroller scroller = new Scroller("&oThis text should be scrolling", 10, 5, '&');
               
                Score scrollerscore = objective.getScore(Bukkit.getOfflinePlayer(scroller.next()));
                scrollerscore.setScore(1);   
            }
           
        }, 20L, 20L);
       
        getCommand("arcade").setExecutor(new ArcadeCommand());

You want to make the Scroller outside of the scheduler, so you only have one instance that you're calling .next() on, otherwise you're making a new Scroller each time.

 

...derp...

EDIT:
Chinwe How can I get the previous string from it so I can board.resetScores? :?

Chinwe
Sorry if its annoying that I tagged you in twice, not sure if the other one worked or not...

Chinwe ?

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

 

You mean the original scroller string, "&oThis text should be scrolling"? You can save it as a variable which you pass into the Scroller constructor and then use later?

 

No I mean as in the text before it changes and goes into a new string. Like so I can save it and then it resets the scores so that string is no longer visible on the scoreboard but the text with the next set of letters will show.
