Question

在这个程序中，每当 else 下的任何语句发生时，它都不会返回状态 0 并执行该状态下的操作，这正是我正在尝试做的。相反，txtStatus 和 txtScore 框继续显示 "Roll again!"，这是跳转到状态 2 时显示的内容。我在这里做错了什么？

   int die1 = 0;
    int die2 = 0;
    int total = 0;
    int state = 0;
    int point = 0;
    //int point2;
    int score = 0;

    //private int score;
    //private int state;
    public Form1()
    {
        InitializeComponent();
    }

Answer 1

可能问题出在这里

if (total != 7 || point != total)
{
    txtStatus.Text = "Roll again!";
    state = 2;
}

如您所见，条件在大多数情况下都是正确的！这是错误的唯一一次是 total == point == 7

Answer 2

我认为你应该将最后一个 else 语句更改为：

if (point == total)
{
    txtStatus.Text = "You are a winner!";
    score++;
    txtScore.Text = Convert.ToString(score);
    state = 0;
}
else if (total == 7)
{
    txtStatus.Text = "You lose. Play again!";
    score--;
    txtScore.Text = Convert.ToString(score);
    state = 0;
}
else
{
    txtStatus.Text = "Roll again!";
    state = 2;
}

解释：当total有除7以外的任何值时，你将state切换为2。正因为如此，当你再次滚动，您会立即转到最后一个 else 语句并执行其中的 3 个 if 语句。在这种情况下，最后的 if 语句始终为真（因为在这种情况下 total 永远不会是 7）因此文本保持 "Roll again" 并且状态永远不会改变（保持 2）。

这将解决您的问题，但我认为您需要更改逻辑（例如，point 始终等于 total，因为可能不需要 point == txtTotal.text == total行为）。

希望对您有所帮助。
