How do i make the program to recognize the certain keys I press? To understand the context: I want to make a game in C (very basic game), so in order to move the object, I want to pres (W A S D),I know how to move it, but I don't know how to make the program understand that I want to do a certain action, when one of those keys are pressed. For example:
if( key == "A"){
x++
}
I know it dose not work like that, but something at least similar.
You can include conio.h (on Windows) or ncurses.h libraries (on Linux) and using functions like getch() for return a char that is pressed by the user. Then you can check if the char is what you want.
You can use kbhit included in conio.h as mentioned in the comments above.A simple example is shown below.
#include <conio.h>
int main()
{
char ch;
if (kbhit()) {
// Stores the pressed key in ch
ch = getch();
printf("%c was pressed.\n", ch)
//do something..
}
return 0;
}
I think this link will be helpful to you.
#include <stdio.h>
#include <conio.h> /* getch() and kbhit() */
int main()
{
char c;
for(;;){
if(kbhit()){
c = getch();
if(c == 'c')
{
printf("%c\n", c);
// more code here..
}
}
}
return 0;
}
as the above answer, but the code must be in infinite loop to scan whenever a key is pressed. and the code will only check if the key 'c' is pressed. you can easily remove the if condition and make it more generalized :)
