Global scoreboards

Global scoreboards, like the name implies, will show global data and text that is THE SAME FOR ALL PLAYERS ON THE SERVER. You can't show translated text / data with this scoreboard.
If you do need to show data / text that may be different for each player, please use player scoreboards.

Unlike other components, scoreboards are not classes since they don't require any special data or event management.
Simply create your scoreboard wherever you need it and store it globally.

It is recommended to expose your scoreboards as a Spring bean.
But if you don't want to, you don't have to.

@Bean
public VitalGlobalScoreboard vitalGlobalScoreboard() {
  return new VitalGlobalScoreboard(
    () -> "Title",
    () -> "Line 1",
    () -> "Line 2",
    () -> "Line 3"
  );
}

Note that the title and lines are both lambda functions.
Every time you change the title or the lines, the title and lines functions will be invoked to produce a freshly updated scoreboard.

To change the title, use setTitle(Function<String>).

vitalGlobalScoreboard.setTitle(() -> "New title");

To change the lines, use setLines(List<Function<String>>).

vitalGlobalScoreboard.setLines(List.of(
  () -> "New line 1",
  () -> "New line 2",
  () -> "New line 3"
));

To add a player to the scoreboard, use addPlayer(Player).

vitalGlobalScoreboard.addPlayer(myPlayer);

To remove a player from the scoreboard, use removePlayer(Player).

vitalGlobalScoreboard.removePlayer(myPlayer);
