how to clear the key buffer while using kbhit() and getch()

由 狂风中的少年 提交于 2020-01-11 13:05:56
问题 heu so I'm using the above stated windows functions which luckily are for windows 2000 and up, but in making a game on the console I've run into a problem: as soon as a key is pressed the console gets passed the kbhit() function no matter if a key is not pressed again... is there some way I can clear the keyboard press buffer so you can't get passed kbhit without a new keypress? If a new lib download is requires I guess I could... but I'm hoping for a windows standard way! Thanks!! 回答1:

Function kbhit to move object in C

问题 This program is detecting right keyboard keys, but when I am trying to move object by pressing arrow on my keyboard, but when i do this it goes in the same line, no matter which arrow i am pressing. I am asking for help to move this object in different possitions. #include <stdio.h> #include <windows.h> #include <time.h> #include <stdlib.h> #include <conio.h> COORD coord={0, 0}; struct Ship{ int x,y; }Ship; struct Ship S; void gotoxy (int x, int y){ coord.X = x; coord.Y = y; // X and Y

C++ loop until keystroke

由 夙愿已清 提交于 2019-12-19 08:17:08
问题 If I want to loop until a keystroke there is a quite nice Windows solution: while(!kbhit()){ //... } But this is neither an ISO-Function nor works on other Operating Systems except MS Win. I found other cross-plattform solutions but they are quite confusing and bloated - isn't there another easy way to manage this? 回答1: You can use the next version of kbhit() for *nix OSes: #include <stdio.h> #include <unistd.h> #include <stdlib.h> #include <termios.h> #include <unistd.h> #include <fcntl.h>

Use of kbhit() with while loop

由 百般思念 提交于 2019-12-11 02:01:56
问题 Here is the program. void main( ) { int h, v; h = 1; v = 10; while ( !kbhit( ) || h <= 80 ) { gotoxy( h, v ); printf( "<--->" ); delay( 200 ); clrscr( ); h = h + 1; } getch( ); } I am making a program in C, in which I have used kbhit() to run a loop until a key is pressed. so here the arrow "<--->" will keep on moving forward until a key is pressed or until it reaches the last pixel of the screen. What I want is that the program should increment h by 1 everytime 'd' is pressed and decrement

PyCharm: msvcrt.kbhit() and msvcrt.getch() not working?

由 亡梦爱人 提交于 2019-12-04 02:50:37
问题 I've tried to read one char from the console in PyCharm (without pressing enter), but to no avail. The functions msvcrt.getch() stops the code, but does not react to key presses (even enter), and msvcrt.kbhit() always returns 0. For example this code prints nothing: import msvcrt while 1: if msvcrt.kbhit(): print 'reading' print 'done' I am using Windows 7, PyCharm 3.4 (the same heppens in idle). What is wrong? Is there any other way to just read input without enter? 回答1: It's possible in a

How to run program whilst listening for user input in C?

由 纵饮孤独 提交于 2019-11-28 00:32:35
I'm trying to make a game that continues running until a key is pressed and then it should take that key in and do something with it then continue running as per normal. How do I do this? I'm on MAC so even though I've come across a windows library called conio.h which can handle this using kbhit() and getch(), I can't get it working for me... // // main.c // conioTesting // // #include <stdio.h> #include "myconio_mac.h" int main(int argc, const char * argv[]) { int counter = 0; while (counter < 2) { if (kbhit()) { char key = getch(); printf("\n Key is %c \n", key); printf("Keyboard hit

Using kbhit() and getch() on Linux

由 北城以北 提交于 2019-11-26 05:36:53
问题 On Windows, I have the following code to look for input without interrupting the loop: #include <conio.h> #include <Windows.h> #include <iostream> int main() { while (true) { if (_kbhit()) { if (_getch() == \'g\') { std::cout << \"You pressed G\" << std::endl; } } Sleep(500); std::cout << \"Running\" << std::endl; } } However, seeing that there is no conio.h , whats the simplest way of achieving this very same thing on Linux? 回答1: The ncurses howto cited above can be helpful. Here is an
