This is what I did to create ne, nw, se, and sw. It seemed way easier than the other patches for ordinal directions. This was on modified Circle 3.0bpl17 - but it *shouldn't* matter which version you're running as I didn't actually make any structural changes to the direction or movement code.
All the standard disclaimers apply. This code worked for me, and *should* work for most everyone else, but if it breaks your mud, don't blame me. Be sure to make a backup of your working mud before you make these changes.
Just for the sake of those who don't know, ! before a line means "change this line from whatever it is in your code to this" and + before a line means to "add this line."
In constants.c, change const char *dirs[] to:
! /* directions */
const char *dirs[] =
{
"north",
"east",
"south",
"west",
"up",
"down",
+ "northeast",
+ "northwest",
+ "southeast",
+ "southwest",
"\n"
};
And then, (also in constants.c) change int rev_dir[] to:
int rev_dir[] =
{
2,
3,
0,
1,
5,
! 4,
+ 7,
+ 6,
+ 9,
+ 8
};
In interpreter.c, add the following lines after "down":
{ "down", POS_STANDING, do_move , 0, SCMD_DOWN },
+ { "northeast", POS_STANDING, do_move , 0, SCMD_NORTHEAST },
+ { "ne" , POS_STANDING, do_move , 0, SCMD_NORTHEAST },
+ { "northwest", POS_STANDING, do_move , 0, SCMD_NORTHWEST },
+ { "nw" , POS_STANDING, do_move , 0, SCMD_NORTHWEST },
+ { "southeast", POS_STANDING, do_move , 0, SCMD_SOUTHEAST },
+ { "se" , POS_STANDING, do_move , 0, SCMD_SOUTHEAST },
+ { "southwest", POS_STANDING, do_move , 0, SCMD_SOUTHWEST },
+ { "sw" , POS_STANDING, do_move , 0, SCMD_SOUTHWEST },
In interpreter.h, change /* directions */ to read:
/* directions */
#define SCMD_NORTH 1
#define SCMD_EAST 2
#define SCMD_SOUTH 3
#define SCMD_WEST 4
#define SCMD_UP 5
#define SCMD_DOWN 6
+ #define SCMD_NORTHEAST 7
+ #define SCMD_NORTHWEST 8
+ #define SCMD_SOUTHEAST 9
+ #define SCMD_SOUTHWEST 10
In structs.h, do the following:
Change the NUM_OF_DIRS define to read:
#define NUM_OF_DIRS 10 /* number of directions in a room */
Then, change the direction defines as follows:
/* Directions: used as index to room_data.dir_option[] */
#define NORTH 0
#define EAST 1
#define SOUTH 2
#define WEST 3
#define UP 4
#define DOWN 5
+ #define NORTHEAST 6
+ #define NORTHWEST 7
+ #define SOUTHEAST 8
+ #define SOUTHWEST 9
If you have OasisOLC, you need to change the room edit menu in redit.c to reflect the new directions. I swiped most of this directly from StormRider's new_exits.patch code, but I had to change some of it to reflect what was going on with Oasis 2.0 - the new_exits patch was written in April of '97, and things have moved on since then. ;)
In redit.c, change redit_disp_menu like this:
"-- Room number : [%s%d%s] Room zone: [%s%d%s]\r\n"
"%s1%s) Name : %s%s\r\n"
"%s2%s) Description :\r\n%s%s"
"%s3%s) Room flags : %s%s\r\n"
"%s4%s) Sector type : %s%s\r\n"
"%s5%s) Exit north : %s%d\r\n"
"%s6%s) Exit east : %s%d\r\n"
"%s7%s) Exit south : %s%d\r\n"
"%s8%s) Exit west : %s%d\r\n"
"%s9%s) Exit up : %s%d\r\n"
"%sA%s) Exit down : %s%d\r\n"
+ "%sB%s) Exit northeast : %s%d\r\n"
+ "%sC%s) Exit northwest : %s%d\r\n"
+ "%sD%s) Exit southeast : %s%d\r\n"
+ "%sE%s) Exit southwest : %s%d\r\n"
! "%sF%s) Extra descriptions menu\r\n"
"%sQ%s) Quit\r\n"
"Enter choice : ",
And then add the following lines after:
room->dir_option[DOWN] && room->dir_option[DOWN]->to_room != -1 ?
world[room->dir_option[DOWN]->to_room].number : -1,
+ grn, nrm, cyn,
+ room->dir_option[NORTHEAST] && room->dir_option[NORTHEAST]->to_room != -1 ?
+ world[room->dir_option[NORTHEAST]->to_room].number : -1,
+ grn, nrm, cyn,
+ room->dir_option[NORTHWEST] && room->dir_option[NORTHWEST]->to_room != -1 ?
+ world[room->dir_option[NORTHWEST]->to_room].number : -1,
+ grn, nrm, cyn,
+ room->dir_option[SOUTHEAST] && room->dir_option[SOUTHEAST]->to_room != -1 ?
+ world[room->dir_option[SOUTHEAST]->to_room].number : -1,
+ grn, nrm, cyn,
+ room->dir_option[SOUTHWEST] && room->dir_option[SOUTHWEST]->to_room != -1 ?
+ world[room->dir_option[SOUTHWEST]->to_room].number : -1,
grn, nrm, grn, nrm
);
Then insert the following into the case statements for REDIT_MAIN_MENU:
case 'b':
case 'B':
+ OLC_VAL(d) = NORTHEAST;
+ redit_disp_exit_menu(d);
+ break;
+ case 'c':
+ case 'C':
+ OLC_VAL(d) = NORTHWEST;
+ redit_disp_exit_menu(d);
+ break;
+ case 'd':
+ case 'D':
+ OLC_VAL(d) = SOUTHEAST;
+ redit_disp_exit_menu(d);
+ break;
+ case 'e':
+ case 'E':
+ OLC_VAL(d) = SOUTHWEST;
+ redit_disp_exit_menu(d);
+ break;
+ case 'f':
+ case 'F':
/*
* If the extra description doesn't exist.
*/
I didn't have any trouble with this *except* I had to 'make clean' before compiling it, otherwise I ended up crashing the mud with a weird segmentation fault (gdb was a *real* help. It told me: "#0 0x19 in ?? () ". So... before you compile this, be sure to 'make clean'.
As for credit, don't worry about it (there's nothing I can see in StormRider's code that asks for credit, either). Anyway. Have fun and enjoy your new directions.
