getch

问题 for (;;) { cout << "You are playing for:" << playtime << "seconds." << endl; cout << "You have " << bytes << " bytes." << endl; cout << "You are compiling " << bps << " bytes per second." << endl; cout << "Press a to buy assembler monkey (produces 1 byte per second)/(cost 10 bytes)" << endl; switch(getch()) { case 'a': bytes = bytes - 10; bps++; break; } bytes = bytes + bps; playtime++; Sleep(1000); system("cls"); } Let's say that's my incremental game. I want refresh my game after 1 second.

问题 I have the following code from one class: class _Getch: def __init__(self): self.impl = _GetchWindows() def read_key(self): return self.impl() class _GetchWindows: def __init__(self): import msvcrt def __call__(self): import msvcrt return msvcrt.getch() And then I have another class that imported _Getch. Within this other class, I tried to use the read_key provided by _Getch to do things in the conditional: r = _Getch() key = r.read_key() print(key) if key = 'a': #do things elif key = 's': #

问题 i have to do a order system for a fastfood restaurant (its just a school project). I have finished the tool already. But the teacher told us to use getch instead of scanf. But i dont understand, how to implent it.. Can i just replace my scanf in the code with getch? I dont need the Echo from Scanf and dont need confirmation with the ENTER-Key. The task was: Create a CMD-Tool in the Programming Language C. NO GUI! The Solution must include the commands „malloc“, „realloc“, „getch“, and free.

问题 I had installed ncurses library in Linux mint and still I can't use getch function in c. I am using Linux mint 18.2. Here is my program: #include <stdio.h> #include <curses.h> int main() { char k; printf("how are you"); k = getch(); printf("%c",k); } and here is the output: ram@ram$ gcc-7 test.c -lcurses ram@ram$ ./a.out how are you�ram@ram$ It does't wait for me to press any key and terminate to quickly. I don't want to install conio.h for Linux. How can I use getch and getche function in

问题 I wrote a code on windows, using the function getch() from stdio . The thing is I have to use an input function that does not require pressing enter. My code compiles and works perfectly on windows. However, this assignment has to run on linux, and when I try to do so, it tells me it does not recognize getch() (or _getch() ). The problem is that according to the assignment, I can not use other includes but stdio.h (and same goes for adding a flag), so I can not use curses.h to solve this. I

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:

问题 I have a getch() function which my tutor gave me, which is getting input from the keyboard without clicking on 'ENTER'. But, when I run it in Ubuntu 12 in Eclipse, I get the following error: tcsetattr(): Inappropriate ioctl for device tcsetattr ICANON: Inappropriate ioctl for device This is my code: #include <stdio.h> #include <unistd.h> #include <termios.h> char getch(); int main(int argc, const char* argv[]) { char c; do { c=getch(); printf("%c",c); } while(c!='q'); return 0; } char getch()

问题 I'm trying to make Tetris game in standard console. I need non-blocking getch(), so the blocks can fall without pressing any key. It would be nice to have function that returns -1 if no key pressed, otherwise the key code. 回答1: It's operating system specific but your library probably has a function called kbhit() or similar that will do this 回答2: This is exactly what you wanted: int getch_noblock() { if (_kbhit()) return _getch(); else return -1; } Basically kbhit() does the job of
