Hikari is Japanese for Light! Light is fast and so is HikariBoard.
@EventHandler
public void onScoreboardUpdate(ScoreboardEvent event){
Player player = event.getPlayer();
//Set the scoreboards title (objective display name) (optional but recommended)
event.setScoreboardName("Test Scoreboard");
//Set a line to always be at the top of the scoreboard (optional)
event.setHeader("---------");
//Set a line to always be at the bottom of the scoreboard (optional)
event.setFooter("---------");
//Write some lines to the scoreboard
//Note: No 'id' is necessary, unlike many scoreboad plugins HikariBoard operates a little differently
event.writeLine("Your Name");
event.writeLine(player.getName());
