Scoreboard board = Bukkit.getScoreboardManager().getNewScoreboard(); for(Player p : Bukkit.getOnlinePlayers()){ p.setScoreboard(board); } Might have mistakes, this is off the top of my head.
i don't want to have a scoreboard per player, because this will not be compatible with scoreboardteams
@Fr33stylerTC you don't have to use a scoreboard per player, you can just use the same scoreboard for multiple people.
What i'm trying to say is i have a board field and make use of MultipleTeams for Prefix of player, Health for all players belowname and i want to have a status, with different score for every player
