        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.clientserverinterface.service.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.

        Specified by:
        reduceLinePoints in interface ch.sahits.game.openpatrician.clientserverinterface.service.IPathConverter
        Parameters:
        initialPoints - list of initial points
        Returns:
        List of points

      • 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.clientserverinterface.service.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.
