Scrolling Text Not Working!

Hey! I have this method using and Chinwe scrolling class, and It is NOT scrolling the text in the sidebar numbered scoreboard!

Code:java

 Scroller scroller = new Scroller("§lWelcome to My Happy Server :D", 12, 1, '§');
                String welcome = scroller.next();

How are you implementing it?

The code you provided is correct usage.

 

onPlayerJoin, I add That. The Problem Is, It Is NOT Scrolling at all ._.

 

HeavyMine13
You have to put in a repeating task that will keep scrolling and displaying the String to the scoreboard.

That will give a null exception to the scoreboard im using. Im using this scoreboard class:

Method In My Join:

Code:java

final SimpleScoreboard scoreboard = new SimpleScoreboard("§a§lMain Lob");
 
final Scroller scroller = new Scroller(
"§lWelcome to My Happy Server :D", 12, 1, '§');
Bukkit.getScheduler().runTaskTimer(plugin, new Runnable() {
 
@Override
public void run() {
test = scroller.next();
}
}, 0L, 3L);
scoreboard.add(test);

Error:

SimpleScoreboard Class:

Code:java

public class SimpleScoreboard {
 
private Scoreboard scoreboard;
 
private String title;
private Map<String, Integer> scores;
private List<Team> teams;
 
public SimpleScoreboard(String title) {
this.scoreboard = Bukkit.getScoreboardManager().getNewScoreboard();
this.title = title;
this.scores = Maps.newLinkedHashMap();
this.teams = Lists.newArrayList();
}
 
public void blankLine() {
add(" ");
}
 
public void add(String text) {
add(text, null);
}
 
public void add(String text, Integer score) {
Preconditions.checkArgument(text.length() < 48,
"text cannot be over 48 characters in length");
text = fixDuplicates(text);
scores.put(text, score);
}
 
private String fixDuplicates(String text) {
while (scores.containsKey(text))
text += "§r";
if (text.length() > 48)
text = text.substring(0, 47);
return text;
}
 
private Map.Entry<Team, String> createTeam(String text) {
String result = "";
if (text.length() <= 16)
return new AbstractMap.SimpleEntry<>(null, text);
Team team = scoreboard.registerNewTeam("text-"
+ scoreboard.getTeams().size());
Iterator<String> iterator = Splitter.fixedLength(16).split(text)
.iterator();
team.setPrefix(iterator.next());
result = iterator.next();
if (text.length() > 32)
team.setSuffix(iterator.next());
teams.add(team);
return new AbstractMap.SimpleEntry<>(team, result);
}
 
public void build() {
Objective obj = scoreboard
.registerNewObjective(
(title.length() > 16 ? title.substring(0, 15) : title),
"dummy");
obj.setDisplayName(title);
obj.setDisplaySlot(DisplaySlot.SIDEBAR);
 
int index = scores.size();
 
for (Map.Entry<String, Integer> text : scores.entrySet()) {
Map.Entry<Team, String> team = createTeam(text.getKey());
Integer score = text.getValue() != null ? text.getValue() : index;
@SuppressWarnings("deprecation")
OfflinePlayer player = Bukkit.getOfflinePlayer(team.getValue());
if (team.getKey() != null)
team.getKey().addPlayer(player);
obj.getScore(player).setScore(score);
index -= 1;
}
}
 
public void reset() {
title = null;
scores.clear();
for (Team t : teams)
t.unregister();
teams.clear();
}
 
public Scoreboard getScoreboard() {
return scoreboard;
}
 
public void send(Player... players) {
for (Player p : players)
p.setScoreboard(scoreboard);
}
 
}

On what line are you getting the NPE?

 

Here is a version with fixed NPE (so no more NPE), but the first line does not appear:

Because you add the scrolling line after you .build() it, you have to make a new scoreboard each time you want it to scroll.

 

RainoBoy97 How will i do that? How can I make a new scoreboard each time?

RainoBoy97 I tried a scheduler with the normal stuff but didnt work. I mean I placed it all in a BukkitRunnable but no difference
