I am trying to create teams with name prefixes using the vanilla scoreboard system. Here is my code:

 

scoreboard = new Scoreboard();

	redTeamScore = scoreboard.createTeam("Red");
	blueTeamScore = scoreboard.createTeam("Blue");
	greenTeamScore = scoreboard.createTeam("Green");

	redTeamScore.setAllowFriendlyFire(false);
	redTeamScore.setNamePrefix(RED + "[RED] " + BOLD);

	blueTeamScore.setAllowFriendlyFire(false);
	blueTeamScore.setNamePrefix(BLUE + "[bLUE] " + BOLD);

	greenTeamScore.setAllowFriendlyFire(false);
	greenTeamScore.setNamePrefix(GREEN + "[GREEN] " + BOLD);

	scoreboard.broadcastTeamCreated(redTeamScore);
	scoreboard.broadcastTeamCreated(blueTeamScore);
	scoreboard.broadcastTeamCreated(greenTeamScore);

 

Then I add a player to the team:

 

scoreboard.func_151392_a(player, "Red")

 

The method returns true. However, in-game, the players' names do not change. What am I doing wrong? Am I missing a packet or something?

I found the problem. Instead of doing:

 

scoreboard = new Scoreboard();

 

I did

 

scoreboard = world.getScoreboard();

 

And it is fixed!
