    • sendPacketToViewers

      default void sendPacketToViewers(@NotNull @NotNull SendablePacket packet)
      Sends a packet to all viewers.

      It is better than looping through the viewers to send a packet since it is here only serialized once.

      Parameters:

    • sendPacketsToViewers

      default void sendPacketsToViewers(@NotNull @NotNull Collection<SendablePacket> packets)

    • sendPacketToViewersAndSelf

      default void sendPacketToViewersAndSelf(@NotNull @NotNull SendablePacket packet)
      Sends a packet to all viewers and the viewable element if it is a player.

      If 'this' isn't a player, then only sendPacketToViewers(SendablePacket) is called.

      Parameters:
      packet - the packet to send

    • getViewersAsAudience

      @NotNull default @NotNull Audience getViewersAsAudience()
      Gets the result of getViewers() as an Adventure Audience.
