getch()是否有替代方法?哪个不会暂停程序? [英] Is there an alternative to getch(); which won't pause the program?

问题描述

我正在以ncurses编写游戏，我有一艘由用户控制的飞船，还有一个自动"装置，可以缓慢移动以杀死您.但是，我正在使用一个包含所有内容的while循环，每次使用getch()时，循环都会暂停并等待输入，这意味着敌人只有在用户输入后才移动.

I'm writing a game currently in ncurses and I have a ship that is controlled by the user and an 'automated' that moves slowly down the lines to kill you. However, I'm using a while loop containing everything and each time I use getch() the loop pauses and waits for input, meaning that the enemy only moves after input from the user.

        c=getch(); //causes a pause until a button is pressed before the next action

        if(c==97) //if a is pressed, move position of '*' left
        {
            dir=-1;

        }

        if(c==100) //if d is pressed, move position of '*' right
        {
            dir=1;

        }

推荐答案

由于您使用的是诅咒，只需调用nodelay或halfdelay或timeout即可使getch成为非阻塞状态，或者让它返回稍等片刻后，如果未按任何键.请参见inopts(3ncurses)手册页.

Since you're using curses, just call nodelay or halfdelay or timeout to make getch non-blocking, or have it return after a short wait if no key has been pressed. See the inopts(3ncurses) man page.
