      • findColonyTargets

        private java.util.List<REFAIPlayer.TargetTuple> findColonyTargets​(AIUnit aiu,
                                                                  AIUnit aiCarrier)

        aiu - The AIUnit to search with.
        aiCarrier - The AIUnit to use as a carrier.
        Returns:
        A list of TargetTuple target choices.

      • initialize

        public boolean initialize​(boolean teleport)
        Initialize the REF. - Find the initial target - Give valid missions to all the units Note that we can not rely on normal AI processing as the "teleporting" Col1-style REF needs to be placed on the map before its first turn starts, so the server should ask this AI where it should arrive on the map. Note also that to find a target we can not just call getMilitaryMission and aim for it as the getMilitaryMission scoring includes distance from starting point, which is what we are trying to determine. So, just choose the best coastal colony. FIXME: Mission assignment is done here because ATM the European AI is prone to send ships full of troops off to attack the rebel navy. If this is fixed check if the normal mission assignment works and drop it from here.
        Parameters:
        teleport - "Teleporting" in is allowed.
        Returns:
        True if the initialization succeeds.
