Method Detail

createPath

public java.util.Optional<javafx.scene.shape.Path> createPath(ch.sahits.game.openpatrician.model.ship.INavigableVessel vessel,
                                                              java.util.List<javafx.geometry.Point2D> pointedPath,
                                                              double scale)

Create a path shape out of a list of points. When the path is created the vessel will be added to the TravellingVessels container.

Specified by:

createPath in interface ch.sahits.game.openpatrician.engine.sea.IPathConverter

Parameters:

vessel - vessel that is traveling the path.

pointedPath - input points.

scale - scaling that is used on the path due to the sacle of the map.

Returns:

shape representing a path.

reduceLinePoints

public java.util.List<javafx.geometry.Point2D> reduceLinePoints(java.util.List<javafx.geometry.Point2D> initialPoints)

No actual reduction of points happens.

Specified by:

reduceLinePoints in interface ch.sahits.game.openpatrician.engine.sea.IPathConverter

Parameters:

initialPoints - list of initial points

Returns:

calculateDuration

public long calculateDuration(ch.sahits.game.openpatrician.model.ship.INavigableVessel vessel,
                              ch.sahits.game.openpatrician.clientserverinterface.service.PathInterpolator interpolator,
                              double fraction)

No real implementation here.

Specified by:

calculateDuration in interface ch.sahits.game.openpatrician.engine.sea.IPathConverter

Parameters:

vessel - that is traveling

interpolator - used to hold the path information

fraction - value between [0,1]. 1 means that the whole distance is traveled.

Returns:

calculated travel duration.
