How to display teams on scoreboards?

I used his tut chasechocolate

and created the folluwing code:

Code:java

 
ScoreboardManager manager = Bukkit.getScoreboardManager();
Scoreboard board = manager.getNewScoreboard();
 
Objective objective = board.registerNewObjective("data", "dummy"); // 16 chars
objective.setDisplaySlot(DisplaySlot.SIDEBAR);
objective.setDisplayName("Headline"); // 32 chars
 
Team t = board.registerNewTeam("team1"); // 16 chars
t.setDisplayName("teamname"); // 32 chars
t.setPrefix("prefix");
t.setSuffix("suffix");
 
OfflinePlayer p = Bukkit.getOfflinePlayer("offlineplayer");
t.addPlayer(p);
 
 
player.setScoreboard(board);

this is part of and command ... so i do /slh sb and the code will run ...

I expected it to show something like:

Code:

Headline
  teamname
    offlineplayer: 0

or something similar ...
but there is NO scoreboard ... nothing diplays ...
If i add this:

Code:java

 
// Score score = objective.getScore(p);
// score.setScore(1337);

i get:

Code:

Headline
offlineplayer:    1337

but still no teamname or something ....

how do i display teamnames?

 

Scoreboards don't do that. Teams are used for the purposes of displaying prefixes/suffixes, along with determining whether players can see certain other invisible players. As of 1.6.4, though, the only way to display team names would be to create a fake offline player and assign it a score which would cause it to be placed in the correct position. However, this doesn't always work, as sometimes scores simply don't work out that way.
