可定制的 TicTacToe 游戏板 Java

Question

我需要创建一种方法来检查 tictactoe 游戏是 PLAYING、DRAW、XWIN 还是 OWIN。但是，我很难编写代码来检查 X 或 O 是否获胜，因为游戏板的大小和获胜所需的大小 (sizeWin) 正在根据用户的输入而变化。而且我被迫为游戏板使用一维数组。我根本不知道从这里去哪里。我最近的想法是使用嵌套 for 循环来按行、列或对角线检查是否获胜，但我不确定如何实现它。如果有人对如何解决此问题有任何提示或有任何其他解决方案，我将不胜感激

private void setGameState(int i) {

    // Check rows
    getLines();
    getColumns();
    getSizeWin();
    for (row = 0; row == lines; row++) {
        for (col = 0; col == columns; col++) {

        }
    }
}

public TicTacToeGame(int lines, int columns, int sizeWin) {

    // linesXcolumns game, starts with X, need sizeWin in a line/column/diag to win
    this.lines = lines;
    this.columns = columns;
    CellValue currentCellValue = CellValue.X;
    this.sizeWin = sizeWin;

    // Creating board according to given size
    int size = lines * columns;
    this.board = new CellValue[size];

    // Setting up board to be empty
    for (int i = 0; i < size; i++) {
        board[i] = CellValue.EMPTY;
    }
}

PS。如果有人调用运算符 TicTacToe(3,4,3)，将打印一个 3 行 4 列的游戏板。获胜的 X 或 O 的数量为 3。

它比看起来要复杂一点，但在你掌握它之后就很简单了。我制作了一个运行良好的函数：

private static String checkGameState() {
    // Looking for errors.
    if (rowCount <= 0 || columnCount <= 0) {
        return "ERROR: Illegal board size: " + rowCount + "*" + columnCount;
    }
    if (boradContent.length != rowCount * columnCount) {
        return "ERROR: boradContent not compatible with rowSize and columnSize.";
    }
    if (sizeWin > rowCount && sizeWin > columnCount) {
        return "ERROR: Board is too small for this sizeWin: " + sizeWin + ".";
    }

    String gameState = "PLAYING";

    // Checking rows
    for (int i = 0; i < rowCount; i++) {
        char currentChar = getField(i, 0);
        int score = 1;
        for (int j = 1; j < columnCount; j++) {
            if (currentChar == getField(i, j)) {
                score++;
                if (score >= sizeWin) {
                    if (gameState.equals("PLAYING")) {
                        gameState = currentChar + "WIN";
                    } else if (!gameState.equals(currentChar + "WIN")) {
                        gameState = "DRAW";
                        return gameState;
                    }
                }
            } else {
                if (j > columnCount - sizeWin) {
                    break;
                }
                score = 1;
                currentChar = getField(i, j);
            }
        }
    }

    // Checking columns
    for (int j = 0; j < columnCount; j++) {
        char currentChar = getField(0, j);
        int score = 1;
        for (int i = 1; i < rowCount; i++) {
            if (currentChar == getField(i, j)) {
                score++;
                if (score >= sizeWin) {
                    if (gameState.equals("PLAYING")) {
                        gameState = currentChar + "WIN";
                    } else if (!gameState.equals(currentChar + "WIN")) {
                        gameState = "DRAW";
                        return gameState;
                    }
                }
            } else {
                if (j > rowCount - sizeWin) {
                    break;
                }
                score = 1;
                currentChar = getField(i, j);
            }
        }
    }

    // Checking diagonally
    // Checking diagonally - from top-left to bottom-right
    for (int i = 0; i < rowCount - sizeWin + 1; i++) {
        for (int j = 0; j < columnCount - sizeWin + 1; j++) {
            char currentChar = getField(i, j);
            int score = 1;
            for (int k = 1; k < sizeWin; k++) {
                if (currentChar == getField(i + k, j + k)) {
                    score++;
                    if (score >= sizeWin) {
                        if (gameState.equals("PLAYING")) {
                            gameState = currentChar + "WIN";
                        } else if (!gameState.equals(currentChar + "WIN")) {
                            gameState = "DRAW";
                            return gameState;
                        }
                    }
                } else {
                    break;
                }
            }

        }
    }

    // Checking diagonally - from top-right to bottom-left
    for (int i = 0; i < rowCount - sizeWin + 1; i++) {
        for (int j = sizeWin -1; j < columnCount; j++) {
            char currentChar = getField(i, j);
            int score = 1;
            for (int k = 1; k < sizeWin; k++) {
                if (currentChar == getField(i + k, j - k)) {
                    score++;
                    if (score >= sizeWin) {
                        if (gameState.equals("PLAYING")) {
                            gameState = currentChar + "WIN";
                        } else if (!gameState.equals(currentChar + "WIN")) {
                            gameState = "DRAW";
                            return gameState;
                        }
                    }
                } else {
                    break;
                }
            }

        }
    }

    return gameState;
}

值得一提的是 rowCount、columnCount、sizeWin 和 boradContent 变量是 class 级变量，我使用了 getField(int X, int Y) 方法，这不是一件很复杂的事情，但更有用。它只是将给定的字段坐标转换为一维数组中的位置并且 returns 它的内容：

private static char getField(int X, int Y) {
    return boradContent[X * columnCount + Y];
}
