C++ 在程序内部重新启动程序&；基于文本的游戏&；C++；

我已经制作这个游戏有一段时间了，但仍然无法解决这个大问题。我很年轻，需要指导。谢谢。我的问题是，当你在游戏中“死亡”时，你会被问到是否要重新启动，如果你说“是”或“是”，那么游戏会按你的要求重新启动，但当我尝试输入任何其他内容时，程序会说我们死了，我被迫进入一个循环。结束循环的唯一方法是在被问及是否要重新启动时键入“否”，从而关闭程序

    std::cout << F; // will print 10

    if (F == 10) {
        int F = 5; // This will declare a new variable F that shadows the previous F
        std::cout << F; // will print 5
    }

改变旧变量，而不是创建新变量

if (sc == "yes" || sc == "y"){
    gameloop = true;
    F = 10;
    W = 10;
    ...
}

您在不同的作用域中使用相同的名称声明不同的变量。

（给两个事物起同一个名字并不意味着它们是同一事物。）

使用两个嵌套循环-一个循环玩一轮游戏，另一个循环重复这些循环直到玩家想要退出

像这样的结构：

int main()
{
    bool quit = false;
    while (!quit)
    {
        // Declare variables for a round here so you don't need to reset them.
        int food = 100;
        int water = 100;
        // ... more game state...
        // Now play a round.
        std::cout << "Let's play." << std::endl;
        bool still_alive = true;
        while (still_alive)
        {
            std::string command;
            std::cin >> command;
            // ... interpret commands ...

            if (food <= 0 || water <= 0)
            {
                still_alive = false;
            }
        }
        std::cout << "Game Over" << std::endl;
        // Ask if the player wants to go again.
        std::string answer;
        // ...
        if (answer == "no")
        {
            quit = true;
        }
        // ...
    }
}

intmain（）
{
bool-quit=false；
而（！退出）
{
//在这里声明一轮的变量，这样就不需要重置它们。
int食品=100；
int水=100；
//…更多游戏状态。。。
//现在打一轮。
std：：cout命令；
//…解释命令。。。

如果
？既然你检查输入是否是否定的，那么它是否是肯定的，或者是无效的输入。请将你的代码转换为。这有两个目的：（1）它增加了可读性，因此使您更有可能得到答案这是一种优秀的调试技术：通常，你会在最小化问题代码的同时自己解决问题。发布MWE也证明你已经尝试自己解决问题。你已经重新定义了
F
，
W
，
c
，
sc
，等等。请调试你的程序，找出你遇到的问题（很多问题）。并认为如果用户类型
die
，您可以将
F
设置为1，当您要求重新开始时，如果用户选择了任何无效的内容，您不会更改
c
值，因此在下一个循环中，此变量再次将
die
设置为值。如果用户类型
yes
，则重新定义
F
和
W
设置10作为值，但在此
if
块之外，您正在将其他
F
和
W
变量与其他值一起使用。您应该了解一下变量范围的cocnet。每当您编写
int var\u name
时，此变量仅存在于这个特定范围内，即两个花括号之间的区域（只有全局变量和静态变量例外，但您的项目中没有）。当访问在多个位置定义的变量时，只使用最内部的作用域，其他作用域不受影响！祝您在未来的游戏开发中好运：）请将您的代码简化为您问题的一部分。您当前的代码包含许多与您的问题无关的内容-最小样本通常看起来类似于良好的单元测试：仅执行一项任务，输入值指定用于再现性。感谢您的帮助，我一定会记住这一点
