Constructor Detail

REFAIPlayer

public REFAIPlayer(AIMain aiMain,
                   ServerPlayer player)

Creates a new REFAIPlayer.

Parameters:

aiMain - The main AI-class.

player - The player that should be associated with this REFAIPlayer.

REFAIPlayer

public REFAIPlayer(AIMain aiMain,
                   org.w3c.dom.Element element)

Creates a new REFAIPlayer and reads the information from the given Element.

Parameters:

aiMain - The main AI-class.

element - The XML-element containing information.

REFAIPlayer

public REFAIPlayer(AIMain aiMain,
                   javax.xml.stream.XMLStreamReader in)
            throws javax.xml.stream.XMLStreamException

Creates a new REFAIPlayer.

Parameters:

aiMain - The main AI-object.

in - The input stream containing the XML.

Throws:

javax.xml.stream.XMLStreamException - if a problem was encountered during parsing.

Method Detail

startWorking

public void startWorking()

Tells this REFAIPlayer to make decisions.

Overrides:

startWorking in class EuropeanAIPlayer

initialize

public Tile 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:

The preferred entry location, or null if no useful preference.

getDefendColonyMissionValue

public int getDefendColonyMissionValue(Unit unit,
                                       Colony colony,
                                       int turns)

Evaluate allocating a unit to the defence of a colony. Temporary helper method for giveMilitaryMission. Only public for testAssignDefendSettlementMission.

Overrides:

getDefendColonyMissionValue in class EuropeanAIPlayer

Parameters:

unit - The Unit that is to defend.

colony - The Colony to defend.

turns - The turns for the unit to reach the colony.

Returns:

A value for such a mission.

getUnitSeekAndDestroyMissionValue

public int getUnitSeekAndDestroyMissionValue(Unit unit,
                                             Tile newTile,
                                             int turns)

Evaluate a potential seek and destroy mission for a given unit to a given tile.

Overrides:

getUnitSeekAndDestroyMissionValue in class EuropeanAIPlayer

Parameters:

unit - The Unit to do the mission.

newTile - The Tile to go to.

turns - How long to travel to the tile.

Returns:

A score for the proposed mission.

alreadySeeking

private boolean alreadySeeking(Unit unit)

Checks if there is already a seek and destroy mission active on for a target unit.

Parameters:

unit - The Unit to check if there is a mission for.

Returns:

True if there is a mission for the unit.

giveNormalMissions

public void giveNormalMissions()

Gives a mission to non-naval units.

Overrides:

giveNormalMissions in class EuropeanAIPlayer
