我正在尝试为具有播放器和计算机掷骰子的游戏编写代码，直到其中一个或两个达到250（这可能使他们打成平手）。玩家和计算机可以从3种模具中选择1种。一个 - 24面双面打结，两个 - 10面双面打印，或三 - 六面模具。如果模具全部相同，则10和6面模具有一个奖励。有2个＆＃34;湖泊＆＃34;如果玩家落入其中，玩家必须在湖的开始之前回到较低的数字，那么还有一个泥泞的沼泽地，玩家在沼泽中所做的每一个动作都被切成两半。每10个位置（10,20,30,40等），玩家随机抽取一张牌。玩家可以随机获得11种不同的牌：
1-4：玩家从1-6开始随机移动
5：玩家从4-11（随机8 + 4）随机前进一步
6：玩家移动到另一个玩家的位置（见下文）
7：玩家回到开头（移动到位置0）
8-9：玩家从1-6
中移回一个随机数量10-11：玩家从4-11
移回一个随机数量我有一些问题。我的第一个问题是每次转弯后模具辊没有变化，它们将保持不变。因此，如果我选择3个骰子，我可能会得到3个随机数，如果我选择再次骰子，我会得到相同的3个数字。
我似乎也无法让玩家计数正确更新。如果玩家总共滚动了18个点并且下一个回合他滚动了14个，则计数将从18变为14。
我的第三个问题似乎是无论我做什么，湖泊的打印声明，泥泞的补丁和赢家公告总是打印。我尝试过一些不同的东西，似乎没什么用。
我是代码编写的新手（这是我写的第四个程序）并且没有广泛的知识来知道什么是错的。代码不必专业，我只是希望它能正常工作。非常感谢任何和所有的帮助。

答案 0 :(得分：2)
以下是我提到的与你提到的三个问题有关的事情：
问题编号1：
您正在设置代码执行开始时的骰子值。从那时起，你根本就没有改变它们。这就是每回合总是滚动相同数字的问题的原因。您可能会认为每次使用die1或任何其他模具变量时，它都会重新执行文件顶部的代码，但它并没有。
文件顶部的代码只执行一次，然后存储在该变量中的值用于程序执行的其余部分。直到你改变它。所以你会想要更像这样的东西：
//Getting the die roll if the player chooses the 24 sided die
if (diechoice.equals ("1")) {
die1 = rn1.nextInt(range1) + minimum1;
System.out.println("Player rolled a " + die1);
System.out.println("Player moves forward " + die1 +" spaces");
p1+=die1;
}
在模具滚动的其他情况下，您还需要更改它。
这样做的另一个好处是你真的只需要一个随机数生成器。实际上，每个骰子实际上并不需要一个。您可以对所有模具使用相同的模具。
问题2：
我不确定掷骰子究竟出了什么问题，如果那里确实出现了问题，但我确实注意到了一些你想要改变对p1所做的事情的地方P2：
+=代替=。即p1 += cardmove5而不是p1 = cardmove5 p1 -= cardmove语句。p2 = p1，而是你有p1 = p2。与计算机返回0相同。您有p1 = 0，但似乎您需要p2 = 0。所以要小心一点。 （还要注意复制粘贴。我猜这就是为什么会发生这种情况）问题3：
这个问题看起来像是因为您使用||运算符而应该使用&&。当您使用||时，您实际上在说＆＃34;或＆＃34;。所以这是第一个声明
if (spacesmoved >= (83) || spacesmoved <= (89))
读为＆＃34;如果spacemoved大于或等于83 OR 小于或等于89＆＃34; ...想一想。是否有任何数字不大于83或小于89？答案是不。每个数字都会满足这个条件。您可能希望使用&&，这意味着＆＃34;和＆＃34;像这样：
if (spacesmoved >= (83) && spacesmoved <= (89))
＆＃34;如果spacemoved大于或等于83 AND 小于或等于89＆＃34;，这只适用于83到89之间的数字。
您还需要在＆＃34; if＆＃34;之后删除分号。该块中的语句和其他类似的块。如果你不这样做，那些条件中的代码就不会被执行。当它发生时，这确实是一个非常难以找到的错误。
另一件要知道的事情是，当你想要在＆＃34; if＆＃34;条件，您必须将它括在花括号{}中，否则，只有第一行将包含在条件中，并且任何后续行将无条件执行。这是导致第三个问题的另一个事实。
最后一件事是你应该尝试使用＆＃34;否则如果＆＃34;和＆＃34;否则＆＃34;声明。它将帮助您的代码流更有意义。我不打算为你做所有的工作，但是这个代码块应该看起来更像这样：
if (p1 >= (83) && p1 <= (89))
{
p1 = (82);
System.out.println("Player landed in a lake, player goes back to space " + p1);
}
else if (p1 >= (152) && p1 <= (155))
{
p1 = (151);
System.out.println("Player landed in a lake, player goes back to space " + p1);
}
else if (p1 >= (201) && p1 <= (233))
{
spacesmoved = (spacesmoved / 2);
p1 -= spacesmoved;
System.out.println("Player landed in mud, players turns are cut in half until player gets out");
}
奖金提示
你学得很好，似乎你正在考虑代码流程。只要继续工作和学习，你就能得到它。
查看括号的用法。使用它们并不会伤害任何东西，但是你使用它们的方式超出了你的需要。
祝你好运！继续学习！
