show

public static void show(Player player, BossBar bossBar, long sortKey)

Shows a bar to a player at its sorted position. Calling this again for a bar the player already sees is a no-op. During a suspension it records the bar without exposing it, so recurring producers do not need their own dialogue checks.


public static void show(Player player, BossBar bossBar)

Shows a bar whose relative order has no domain-specific key.
