Class BoardGeometry

java.lang.Object

gui.BoardGeometry

public class BoardGeometry
extends java.lang.Object

provide the geometry for the backgammon board.

This is overkill and provides a singleton instance via BoardGeometry.getBoardGeometry().

getBoardRectangle

public java.awt.Rectangle getBoardRectangle()

get a rectangle bounding the whole baard

Returns:

the bounding rectangle

getBoardGeometry

public static BoardGeometry getBoardGeometry()

BoardGeometry is a singleton class. Use this method to get the sole instance

Returns:

the Geometry instance.

getBarBounds

public java.awt.Rectangle getBarBounds()

the bouards of the bar relative to the board.

Returns:

the bounds of the Bar (relative to the Board)

getPointRectangle

public java.awt.Rectangle getPointRectangle(int pointNumber)

get the bounding box for a point.

Parameters:

pointNumber - which point? The top left point is 24, the top right point is 13 the bottom right point is 12 the bottom left point is 1

Returns:

the bounding bax (relative to the Board) for the given point number.

diskAt

public java.awt.geom.Ellipse2D diskAt(int k,
                                      boolean isDownTriangle)

location of a piece disk relative to the containing point

Parameters:

k - disk location, where 1 is closest to the edge of the board

isDownTriangle - true if the point points down

Returns:

an ellipse (actually a circle) relative to the bounding box of the enclosing point.
