Constructor Detail

player

public player(board ib,
              int iside)

create a player.

Parameters:

ib - the board that is used.

iside - the side the player takes: board.P1 or board.P2

player

public player(board ib,
              int iside,
              boardview ibv)

create a player for applet mode: the player calculates in a separate thread, and wait 4 seconds before answering.

Parameters:

ib - the board that is used.

iside - the side the player takes: board.P1 or board.P2

ibv - the boardview it must answer to.

Method Detail

setstrength

public void setstrength(int l)

determines how far the computer looks ahead, higher value plays better, but takes more time. I think even values are better, because that gives the opponent the last move, but that is personal.

setweight

public void setweight(int[] w)

set the weight vector this player should use.

ask

public void ask(java.lang.String s)

the method you can call if you want this player to think of a move in a separate thread. This function returns immediately, so the caller can do something different. The answers will be given after 4 seconds or longer to the boardview by the method answer.

Parameters:

s - a string that is not used. It can be used for comment by a caller. Do not take it too seriously: it is an inside joke to include comment in extra parameters.

run

public void run()

the method that will run in a separate thread. Do not call this function yourself, but use ask.

Specified by:

run in interface java.lang.Runnable

bestmove

public int bestmove()

this functions returns the move that this player thinks is best. Use this function if you just want the best move, no extra threads and no delays.

Returns:

a move
