    Question Need help with Console Keyboard Input

    I'm still a bit new to programming, but I decided to write an RPG and after a good start I got stuck at one point. Can anyone please tell me how can I, using the console, get keyboard input??? I don't mean just a

    cin<<???; or cin.get .

    How can I make it so that if someone pesses the key (arrow up) the cursor in my menu will move up one position, of if someone presses M the menu will pop up, or if the arrow down is pressed the player character will move down one position. I know how to program the functions, menus, etc, I just don't know how to avoid the typing in of commands. I was told it can be easily done with OpenGL, or others, but I wanna stick to basics. I wanna make it so the computer will wait until you press the key, then execute the function, etc.

    Thanks for any feedback.

    Check out kbhit() in conio.h. Just have something like:
    Code:
    char key;
    if( kbhit( ) )
    {
      key = getch();
      switch( key )
      {
        // Handle all your keys here
    
        // 27 is decimal representation of ESC key
        case 27:
          // Call a function or
          // Quit program!
          break;
      }
    }

    Write a program that prints out the ASCII code of the button you press.
    Code:
    if(kbhit())
    {
       Key=getch();
       cout << (int)Key << endl;
    }

    red_baron, I thank you for that. I coded a function to display the values of the keys, I had about a quarter of the list you have. Thanks.
