我是非常新的编码，所以不要很挑剔，如果我犯了一个简单的错误...我自学成才，所以你是唯一一个我可以问。感谢大家谁会帮助！
我试着用做一些类似“太空射手”的东西<curses.h>，但是它总是给我写分段错误，我不明白为什么。我想我可以给予你我所有的代码，这样你就可以理解游戏的逻辑，但是我想我的问题可能是从诅咒初始化开始到结束...也许我错过了刷新（）或类似的东西？

正如上文评论所述：这不是一个诅咒的问题。相反，有许多情况下，你试图访问world[][]数组之外的元素，这就是导致segfault的原因。我没有详细介绍每一个示例，但是，例如，考虑“控制播放器”部分。在“a”（左）处理程序，您可以正确地将单元格的范围从0到（但不包括）sizex...，然后（有时）修改偏移量sizex处的单元格，这超出了范围。
你可以用一种边界安全的方式重写这一节，顺便说一下，这样会更高效：
注意，这只是需要检查边界的一个地方。
同时，由于这个 * 是 * 标记的curses...注意整个程序可以很容易地转换为curses：
1.将
printf()的所有示例更改为printw()。1.将
system(clear)的所有示例更改为erase()。1.将
usleep()更改为napms()（除以1000）。1.将
endwin()移到末尾。1.将
nodelay()移到第一个getch()之后。1.在最后一个
erase()之后添加一个nodelay(stdscr, FALSE)。进一步的调整将使它工作得更好。
