我必须使用模拟智能来实现connect4。它已经可以工作，但是非常慢。我们必须得到两个玩家的威胁。威胁是一行中有3个硬币，在行之间或两端有一个空字段。我只想在每次移动后仅计算新威胁，并删除不再威胁的威胁。我写了一些方法来检查每个方向，如果最后一步有新的威胁。

方法真的很高，也有一个错误..但我找不到它。您能否给我一些技巧，说明如何更好地实现这些方法？
谢谢

编辑1：

perhebs您应该只看第一种方法。我采取最后一步，并检查tehre是否是包括最后一步在内的任何威胁。因此我检查同一位玩家行中是否还有另外两个硬币构成威胁。大A是最后一步，我想检查一下小A是否造成威胁：

| | a | A | a | | | |
例如，我检查A的右边的字段是否为a，而A的左边的字段是否为a，如果为真，则检查是否周围有一个空字段，以便您可以连续获取4

| | | A | a | a | | |

| a | a | A | | | | |

| | | A | a | | a | |

| | | A | | | a | a |

依此类推..我检查了威胁的所有可能性。在行之后，我将其用于列和对角线

您看到更好的解决方案了吗？

private Field row(int row, int column, int Player) {

        boolean check = false;

                return field;
            }
        }
        return null;
    }

我将从4个不同点调用该方法。你这样行吗？

最佳答案

为什么以所有神圣的名义，您有N次被复制粘贴的相同的血腥代码？唯一的区别是血腥数字在变化。将它们重写为一个循环，然后只有一点可以检查其正确性。
