Reversi (Othello) Java简单程序返回错误的步骤

Question

我一直在尝试实现简单的程序，返回Reversi / Othello游戏的有效移动。不幸的是，它不起作用，我真的看不出原因。它返回2,2，这肯定不是有效的移动。

//myColor, opponentColor, Reversi move etc. are already defined.

如果你指出我系统中的缺陷，我会很高兴的。

@Override
public ReversiMove makeNextMove(int[][] board) {

    for (int y = 0; y < 8; y++) {
        for (int x = 0; x < 8; x++) {
            if (board[y][x] != myColor && board[y][x] != opponentColor) {
                int nextX = x + 1;

                while (nextX < 7 && board[y][nextX] == this.opponentColor) {
                    if (board[y][nextX + 1] == this.myColor) {
                        return new ReversiMove(y,x);
                    }
                    nextX++;
                }

                nextX = x - 1;

                while (nextX > 0 && board[y][nextX] == this.opponentColor) {
                    if (board[y][nextX - 1] == this.myColor) {
                        return new ReversiMove(y,x);
                    }
                    nextX--;
                }

                int nextY = y + 1;

                while (nextY < 7 && board[nextY][x] == this.opponentColor) {
                    if (board[nextY + 1][x] == this.myColor) {
                        return new ReversiMove(y,x);
                    }
                    nextY++;
                }

                nextY = y - 1;

                while (nextY > 0 && board[nextY][x] == this.opponentColor) {
                    if (board[nextY - 1][x] == this.myColor) {
                        return new ReversiMove(y,x);
                    }
                    nextY--;
                }

                nextX = x + 1;
                nextY = y + 1;

                while (nextX < 7 && nextY < 7 && board[nextY][nextX] == this.opponentColor) {
                    if (board[nextY + 1][nextX + 1] == this.myColor) {
                        return new ReversiMove(y,x);
                    }
                    nextX++;
                    nextY++;
                }

                nextX = x - 1;
                nextY = y - 1;

                while (nextX > 0 && nextY > 0 && board[nextY][nextX] == this.opponentColor) {
                    if (board[nextY - 1][nextX - 1] == this.myColor) {
                        return new ReversiMove(y,x);
                    }
                    nextX--;
                    nextY--;
                }

                nextX = x + 1;

            }

有时指的是：
