我必须创造yahtzee游戏及其方法，如满屋，小直，大直，3种，4种，和机会。现在这是我到目前为止所做的事情，我想知道我的方法是否正确，而且我也很难弄清楚如何检查它的yahtzee，3种，4种，等等，这是我的主要方法。该程序由七个卷组成，每个卷最多可以有两个子卷

答案 0 :(得分：0)
基本上我想找出一种方法来检查它的满屋，3种，4种等等
三卷后你有6个骰子。在3次滚动后对用户保留的骰子数组进行排序。
Yahtzee：((die[0] == die[4]) || (die[1] == die[5]))
4种：((die[0] == die[3]) || (die[1] == die[4] || (die[2] == die[5]))
小直，3次测试（x = 3,4,5）：((die[x] - die[x-3]) == 3)
大直，2次测试（x = 4,5）：((die[x] - die[x-4]) == 4)
等。
机会：由用户决定，对吧？
除非我遗漏了某些东西（我在Yatzee上有点生疏），这应该是相当简单的。
