java - 无法垂直检测 connect 4 win

Question

现在我有一个学校作业，我必须使用数组在没有 gui 的情况下用 java 创建一个 connect 4 游戏。到目前为止，我已经能够让游戏检测到水平四连，但我似乎无法检测到垂直四连。最初我的数组是 6x7，但我已将其更改为 5x5，只是为了测试交换数组维度的概念。为了减少困惑，我只包含了垂直检测的代码部分。

for (column = 0; column < board.length; column++) {

            count_piece = 0;
            max = 0;
            for (row = 0; row < board.length; row++) {
                if (max < count_piece) {
                    max = count_piece;
                }
                if (board[column][row] == 'X') {
                    count_piece++;
                } else {
                    count_piece = 0;
                }

            }

        }
        System.out.println(max);
        if (max == 4) {
            System.out.println("\nYou Win!");
            break;
        }

如果您需要更多信息或有任何不清楚的地方，请告诉我，我很乐意提供更多信息。

编辑:这是带有倒循环的一个。

for (row = 0; row < board.length; row++) {
        count_piece = 0;
        max = 0;
        for (column = 0; column < board.length; column++) {

            if (max < count_piece) {
                max = count_piece;
            }
            if (board[column][row] == 'X') {
                count_piece++;
            } else {
                count_piece = 0;
            }

        }

    }

如何反转循环，使内部循环更改为列而不是行？

还要让您的内部循环采用您所在的单个数组的长度。

因此，不要使用 board.length，而是使用 board[i].length

我认为你的内部循环中的逻辑是错误的......

试试这个:

if (board[row][column] == 'X') {
    count_piece++;
    if(count_piece == 4) {
        System.out.println("you win");
        return;
    }
} else {
    count_piece = 0;
}

这里是任意大小数组的水平和垂直检查

int count_piece = 0;

        //Checking Vertical Win
        for (int row = 0; row < board.length; row++) {
            count_piece = 0;
            for (int column = 0; column < board[row].length; column++) {

                if (board[row][column] == 'X') {
                    count_piece++;
                    if (count_piece == 4) {
                        System.out.println("you win");
                        return;
                    }

                } else {
                    count_piece = 0;
                }


            }
        }

        //Checking Horizontal Win
        for (int column = 0; column < board.length; column++) {
            count_piece = 0;
            for (int row = 0; row < board[column].length; row++) {

                if (board[row][column] == 'X') {
                    count_piece++;
                    if (count_piece == 4) {
                        System.out.println("you win");
                        return;
                    }

                } else {
                    count_piece = 0;
                }


            }
        }
