我已经编写了一个程序，我们必须编写一个简单的Gomoku程序。我以为我拥有这一切，但是当我编译并运行时，即使我只有4种，即使它们不是彼此相邻，它也会引发胜利。 （如果连续五个...... X或O，它应该只能取胜。）我觉得我应该在每回合之前将我的计数器重置为0，但我不确定我应该在哪里做到这一点。任何提示将不胜感激！

在检查胜利条件的所有三个函数中都存在问题：isHorizontalWin，isVerticalWin和isDiagonalWin。所有三个都增加变量count，但是这个变量永远不会设置回零。另外，检查是否应该在循环内部进行count == 5。这是一个如何修复isHorizontalWin的示例：
public static boolean isHorizontalWin(char[][] map, int player)
{
int count = 0;
int r;
int c;
for (int i = 0; i < map.length; i++)
{
for (int j = 0; j < map.length; j++)
{
if (map[i][j]==(player))
{
r = i;
c = j;
while (r >= 0 && r <= 18 && c >= 0 && c <= 18 && map[r][c] == player)
{
count ++;
r += 0;
c += 1;
}
if (count == 5)
{
return true;
} else {
count = 0;
}
}
}
}
return false;
}
