Question

我正在为学习目的制作一款简单的游戏，最近我遇到了这个问题。请记住，我仍然是一个伟大的初学者。当我从菜单进入游戏并在＆＃34;命令行＆＃34;我立即饿死并脱水。我已经能够连接互联网几天了，而且我已经阅读了整个程序，但我找不到任何错误。

Answer 1

您的一些if语句执行赋值而不是比较

if (hunger = 100){
            starve();
        }

您可能需要将=更改为==

在编译时启用警告，如果您还没有这样做。

Answer 2

由于

//   b takes you back to the command line
void b(){
    std::cin >> commandLine;
}

b没有带你回到命令行只是等待一个字符被读取然后它返回。如果你想回去，你应该按照你的方式来做。例如，退出播放将返回到菜单循环，显然使用menuLoop = 1，因此它将退出整个程序但是通过修改，这不是一个糟糕的循环系统。

编辑：我已经在＆＃34;命令行＆＃34;中看到了你的意思。

Answer 3

像其他人所说的那样，你有很多条件意外拼写为作业。

事实上，b()函数正在吃后续命令。

也许你应该

使用std::getline()一次读取一行命令
或在std::cin.ignore()内使用b()实际消费直至行尾

PS。由于使用全局变量，我很难验证游戏循环逻辑。我只知道在/step之后/step被忽略而没有效果。将输入与循环控件分开，并尝试删除全局变量。

Answer 4

INFO 不必每次都写std::cout，而只需在开头写using namespace std;，就不必写std::cout，而只需写cout << "" ;

控制台游戏无法正常工作
