    I worked on something like this earlier for a "Mists of Avalon" thing. Bacially, you display all your options, right? Like so:

    Code:
    Items ---
    --------------------
    Elixir
    Heal
    DP Up
    MP Up
    Level Up
    Next, using printf() and gotoxy, you would show the first location of the arrow thing.

    Code:
    Items ---
    --------------------
    Elixir                 <
    Heal
    DP Up
    MP Up
    Level Up
    Finally you'd just put in a loopand check to see if the arrow keys or enter is pressed:

    Code:
    while (keyPressed!=K_ENTER) // Assume K_ENTER has already been defined
    {
         if (keyPressed == UP)
         {
              gotoxy(x,y); // where x and y are the coordinates of the item
              printf("<");
         }
         ...
    }
    Hope that helps!

    Well I'm sorry if you don't get it, it can't be that hard to put it all together.

    Like so:

    #define K_ENTER 13

    Then you'd use a function like getch() and test to see if Enter was pressed. Red_Baron's Dungeons of Moria game has the source code with it. One of the header files, keys.h, defines all the keys I think there are. You may find it useful .

    Use google to search for ASCII. The fourth or fifth site that comes up holds an Ascii table and is even named www.asciitable.com.

    If you need it as source code, Red_Baron's Dungeons of Moria game has the source code with it. One of the header files, keys.h, defines all the keys I think there are.

    When in doubt, read the FAQ.
    Then ask a smart question.

    Well, actually keyPressed is just a variable. I made my own gotoxy() function, works quite well. With the keyPressed thing:

    Code:
    int keyPressed = GetKey();
    
    ...
    
    int GetKey()
    {
         int result = getch();
         return result;
    }
    Some thing like that. Hope that helps. And about the gotoxy() thing, I can post the code on that later, I don't have it with me right now.

    "getch()" will not work on windows machines. Why? Because it will not "move" until the ENTER key is pressed. You must hunt for the header "conio_mingw.h" and include it into your project. Then call the function "_getch()".

    Sorry works fine for me. Though I do have other code in there besides just what I showed, but I don't remember it offhand. I'm on the wrong computer right now.

    here..

    This nifty program that I wrote prints
    the keycodes of almost every key that you press...
    (except "Control", "Alt" , etc )
    PHP Code:
    #include <stdio.h>
    #include <conio.h>

    main()
    {
        
    char c;
        
        
    printf("KEY\tCODE\n");

        while ((
    getch()) != 27)
        {
            
    printf("%3c\t%4d\n"c, (int)c);
            
    fflush(stdin);
        }
