Method Details

randomBoard

public static State randomBoard(double arrowDensity)

Generates a random Amazons boardstate.

initialBoard

public static State initialBoard()

Generates the starting Amazons board state.

parseState

public static BoardState parseState(Map<String,Object> messageDetails)

Parses the occupancy board and queen positions from a GAME_STATE_BOARD or GAME_ACTION_START message.

If the board received from the server is incoherent in some way (e.g., it is missing a queen), then this will return null.

parseMove

public static int parseMove(BoardState state,
 Map<String,Object> details)

Formats the message details of a message of the type GAME_ACTION_MOVE into the standard integer representation.

If the start position in the received move does not match any of the state's queens, then the player will be set to -1.

getStartPosition

public static ArrayList<Integer> getStartPosition(int move)

Takes a move from the standard integer encoding and returns a server- appropriate ArrayList that represents it's starting position.

getEndPosition

public static ArrayList<Integer> getEndPosition(int move)

Takes a move from the standard integer encoding and returns a server- appropriate ArrayList that represents it's starting position.

getArrowPosition

public static ArrayList<Integer> getArrowPosition(int move)

Takes a move from the standard integer encoding and returns a server- appropriate ArrayList that represents it's starting position.
