    • addRunCallback

      public NavigatorParameters addRunCallback(Runnable callback)
      Adds a Runnable callback that will be called every tick while the path is running.
      Parameters:
      callback - The callback to add

    • addSingleUseCallback

    • attackDelayTicks

      public int attackDelayTicks()
      Returns:
      The number of ticks to wait between attacks
      See Also:

    • attackDelayTicks

      public NavigatorParameters attackDelayTicks(int ticks)
      Sets the delay between attacks. When attacking a target using an aggressive target strategy, the NPC waits for a certain number of ticks between attacks to avoid spamming damage to the target. This determines the number of ticks to wait.
      Parameters:
      ticks - The new number of ticks to wait between attacks

    • attackRange

      public double attackRange()
      Returns:

      See Also:

    • attackRange

      public NavigatorParameters attackRange(double range)
      When using aggressive NPC navigation, the NPC will wait until close enough to the target before attempting to use the attackStrategy(). This parameter determines the range in blocks squared before the target will be valid to attack.
      Parameters:
      range - The new attack range, in blocks

    • attackStrategy

      public AttackStrategy attackStrategy()
      Returns:
      The AttackStrategy currently in use or the defaultAttackStrategy() if not configured (may return null)

    • attackStrategy

      public void attackStrategy(AttackStrategy strategy)
      Sets the AttackStrategy for use when attacking entity targets.
      Parameters:
      strategy - The strategy to use
