Method Detail

doMove

public static FigurData[] doMove(int mode,
                                 FigurData[] figs,
                                 int from,
                                 int to,
                                 FastFace fastFace,
                                 int id)

used by F4Daemon, engine and gui

Parameters:

mode - 0 use null (engine) , 1 use kill (gui) , 2 use kill and do some rule checking (serverside)

figs -

from - should be changed to represent locations in order to be able to deal with piece E type as well

to - should also be changed (see from)

fastFace -

id -

Returns:

the resulting pieces

doMove

public static FigurData[] doMove(int mode,
                                 FigurData[] figs,
                                 int from,
                                 int to,
                                 FastFace fastFace)

this method is used by XiStratPanel and Engine

Parameters:

mode - 0 use null (engine) , 1 use kill (gui)

figs -

from - should be changed to represent locations in order to be able to deal with piece E type as well

to - should also be changed (see from)

fastFace -

Returns:

the resulting figures

getNextEdge

public static int getNextEdge(FigurData fig,
                              FastFace fastFace)

Deprecated. now use getNextFEdge

assumes that next stand would not be < 0 (else returns -1)

edge labels start at 0 (for permutations at 1 though)

Parameters:

fig - fig.stand is in [0, polygons-1]

getNextFEdge

public static int getNextFEdge(FigurData fig,
                               FastFace fastFace)

edge labels start at 0 (for ExportData permutations at 1 though later on in the process)

Parameters:

fig - fig.stand is in [0, faces - 1]

assumes fig is type D or E

Returns:

-1 in case next stand would be < 0, else next edge label is returned

getNextFEdge

public static int getNextFEdge(int stand,
                               int location,
                               int distIE,
                               FastFace fastFace)

edge labels start at 0

Parameters:

stand - is in [0, faces - 1]

location - may NOT point to a hole

Returns:

-1 in case next location would point to a stand with < 0

getNextP

public static int getNextP(FigurData fig,
                           FastFace fastFace)

used to compute the next edge for figure D

getNextF

public static int getNextF(FigurData fig,
                           FastFace fastFace)

used to compute the next edge for figure D (used in ExportData for figure specific groups...)

createAllFig

public static java.util.LinkedList<FigurData[]> createAllFig(FigurData[] _figures,
                                                             java.util.LinkedList allMoves,
                                                             FastFace fastFace)

used in loading a game

reconstructing all positions of all times of a game by help of the start position and all moves
