Constructor Detail

House

public House(java.awt.Dimension size,
             java.net.URL imageURL,
             java.net.URL areaDescription,
             java.net.URL pathAreaDescription)

Constructs a new House with the given parameters.

Parameters:

size - the actual size of the house in pixels

imageURL - the URL of the background image

areaDescription - the URL of the file in which the real world areas are specified

pathAreaDescription - the URL of the file in which the path areas are specified (these are used to calculate paths from one "real world area" to another one)

Method Detail

getArea

public Area getArea(java.lang.String id)

Returns the Area with id.

Parameters:

id - the ID of the Area to be returned

Returns:

the Area with id

getPathArea

public PathArea getPathArea(java.lang.String id)

Returns the PathArea with id.

Parameters:

id - the ID of the PathArea to be returned

Returns:

the PathArea with id

getRandomPathArea

public PathArea getRandomPathArea()

Returns a random path area. This is used for generating random movement if no real world updates are available.

Returns:

a random path area

getImageURL

public java.net.URL getImageURL()

Returns the URL of the background image of this house.

Returns:

the URL of the background image of this house

getSize

public java.awt.Dimension getSize()

Returns the size of this house.

Returns:

the size of this house

computePath

public java.util.Vector computePath(PathElement from,
                                    PathElement to)

Calculates a path from the current PathArea of the updated Area (real world coordinates). When a point is reached, the person that has reached the point should update its current PathArea.

Parameters:

from - the current PathElement the Person for which the path shall be computed is in

to - the destination PathElement

Returns:

a Vector with the computed PathElements

paintInto

public void paintInto(java.awt.Graphics g)

Paints the Areas into g depending on settings made in the SpyApplet.

Parameters:

g - the Graphics instance to paint into
