Beste Option für Scoreboard updaten?

[Felix.]

Moin,
ich habe ein kleines Plugin programmiert, was den Abstand zwischen 2 Spielern anzeigt.
Wenn ich das Scoreboard setze werden die Blöcke ja angezeigt, nur leider weiß ich nicht, wie ich es am besten Updaten kann. Hab versucht, mir vom Scoreboard die nötigen Daten zu holen, ohne Erfolg.
Ich danke für eure Hilfe.
