                                 Location target)

Creates a mission for the given AIUnit.

Parameters:

aiMain - The main AI-object.

aiUnit - The AIUnit this mission is created for.

target - The object we are trying to destroy. This can be either a Settlement or a Unit.

UnitSeekAndDestroyMission

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

Loads a mission from the given element.

Parameters:

aiMain - The main AI-object.

element - An Element containing an XML-representation of this object.

UnitSeekAndDestroyMission

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

Method Detail

doMission

public void doMission(Connection connection)

Performs the mission. This is done by searching for hostile units that are located within one tile and attacking them. If no such units are found, then wander in a random direction.

Specified by:

doMission in class Mission

Parameters:

connection - The Connection to the server.

getDisembarkPath

private PathNode getDisembarkPath(Unit unit,
                                  Tile start,
                                  Tile end,
                                  Unit carrier)

isValid

Check to see if this is a valid hostility with a valid target.

Overrides:

isValid in class Mission

Returns:

True if this mission is valid.

getTransportDestination

public Tile getTransportDestination()

Specified by:

toXMLImpl in class FreeColObject

Parameters:

out - The target stream.

Throws:

javax.xml.stream.XMLStreamException - if there are any problems writing to the stream.

writeAttributes
