我的五子棋游戏获胜条件有问题，其中我迭代 2D 数组寻找与每个玩家相关的符号。我有典型的嵌套 for 循环，该循环遍历数组，并且每次找到符号时计数都会增加。但是，我根本无法让它在迭代后显示计数，就像它甚至没有运行循环一样。函数标题是我的老师给的，我不是在寻找讲义，但我真的傻眼了，感觉它是我错过的非常简单的东西。函数中的sout永远不会显示。我没有正确迭代行/列吗？当移动到下一行/列时，计数应该重置，我认为它正在这样做。
我认为这可能是我下面的主要函数结构没有正确调用它，但我已经搞乱了几个小时。抱歉，它很乱而且太多了。 HorizontalWin 和 VerticalWin 函数位于底部。它们在主体中被调用两次，因为我不确定 hasPLayerWon 是否正确返回。

我尝试过多种方法。我尝试通过使用播放器作为布尔值而不是 currentPlayer int 来迭代函数。我尝试通过更改各自的 for 循环中的行/列来以不同的方式迭代数组，但它开始变得混乱并且从未起作用。我尝试在 else 语句中将计数重置为零。我已经将 sout 放置在多个位置，它们唯一不显示的情况是在嵌套 for 之后的 if 语句内部时。这段代码几天前就可以工作，但在重写改变循环工作方式的不同部分之前我从未彻底测试过它，现在它根本不起作用。
您的代码的问题在于
currentPlayer每次在循环中使用
currentPlayer++;在
isHorizontalWinisVerticalWincurrentPlayercurrentPlayer解决此问题的最简单方法可能是将
isHorizontalWinisVerticalWinif (currentPlayer % 2 != 0) {
// player 1 checks
} else {
// player 2 checks
}
此外，您的
