Alright guys, I hope this will help with adding more items to zedit. The original thread is here . I will be using planet_name for my example.

Alright, lets get started.

ZEDIT.C

1. Search void zedit_setup

Find this line:
Code:
if (zone_table[OLC_ZNUM(d)].builders) zone->builders = strdup(zone_table[OLC_ZNUM(d)].builders);

Now under it add:
Code:
++ zone->planet_name = strdup(zone_table[OLC_ZNUM(d)].planet_name);

2. Now search for zedit_save_internally

Find this line of code:
Code:
free(zone_table[OLC_ZNUM(d)].builders);

Under it add:
Code:
++ free(zone_table[OLC_ZNUM(d)].planet_name);

Now scroll just a couple lines down and find this line:
Code:
zone_table[OLC_ZNUM(d)].builders = strdup(OLC_ZONE(d)->builders);

Under it add:
Code:
++ zone_table[OLC_ZNUM(d)].planet_name = strdup(OLC_ZONE(d)->planet_name);

3. Now search for zedit_disp_menu

Find this line:
Code:
"%sM%s) Level Range : %s%s%s\r\n"

Under it add:
Code:
++ "%sO) Planet : %s%s%s\r\n"

Scroll down a couple of lines and find this line:
Code:
grn, nrm, levels_set ? cyn : yel, lev_string,

Under it add:
Code:
++ grn, nrm, yel, OLC_ZONE(d)->planet_name ? OLC_ZONE(d)->planet_name : "None.",

4. Now search zedit_parse

Find this block of code:
Code:
case 'm': case 'M': /*** Edit zone level restrictions (sub-menu) ***/ zedit_disp_levels(d); break;

Under it add:
Code:
case 'o': case 'O': /* Edit zone planet. */ write_to_output(d, "Enter planet name : "); OLC_MODE(d) = ZEDIT_ZONE_PLANET; break;


Find this block of code:
Code:
case ZEDIT_ZONE_TOP: /* Parse and add new top room in zone and return to main menu. */ if (OLC_ZNUM(d) == top_of_zone_table) OLC_ZONE(d)->top = LIMIT(atoi(arg), genolc_zonep_bottom(OLC_ZONE(d)), 32000); else OLC_ZONE(d)->top = LIMIT(atoi(arg), genolc_zonep_bottom(OLC_ZONE(d)), genolc_zone_bottom(OLC_ZNUM(d) + 1) - 1); OLC_ZONE(d)->number = 1; zedit_disp_menu(d); break;

Under it add:
Code:
++/*-----------------------------------------------------------------------*/ ++ case ZEDIT_ZONE_PLANET: ++ /* Name Planet Zone and return to main menu. */ ++ if (genolc_checkstring(d, arg)) { ++ if (OLC_ZONE(d)->planet_name) ++ free(OLC_ZONE(d)->planet_name); ++ else ++ log("SYSERR: OLC: ZEDIT_ZONE_PLANET: no planet list to free!"); ++ OLC_ZONE(d)->planet_name = strdup(arg); ++ OLC_ZONE(d)->number = 1; ++ } ++ zedit_disp_menu(d); ++ break;

5. Close Zedit.c

DB.C

6. Search void destroy_db

Find this line
Code:
if (zone_table[cnt].builders) free(zone_table[cnt].builders);

Under it add:
Code:
++ if (zone_table[cnt].planet_name) ++ free(zone_table[cnt].planet_name);

7. Search for void load_zones

Find this line:
Code:
line_num += get_line(fl, buf); if ((ptr = strchr(buf, '~')) != NULL) /* take off the '~' if it's there */ *ptr = '\0'; Z.name = strdup(buf); parse_at(Z.name);

Under it add:
Code:
++ line_num += get_line(fl, buf); ++ if ((ptr = strchr(buf, '~')) != NULL) /* take off the '~' if it's there */ ++ *ptr = '\0'; ++ Z.planet_name = strdup(buf);

8. Close db.c

DB.H

9. Search zone_data

find this line:
Code:
struct reset_com *cmd; /* command table for reset */

and under it add:
Code:
++ char *planet_name;

10. Close db.h

OASIS.H

11. Search for #define ZEDIT_ZONE_CLAIM and under it add:
Code:
++#define ZEDIT_ZONE_PLANET 27

12. Close oasis.h

GENZON.C

13. Search for create_new_zone

Find this line:
Code:
zone->max_level = -1;

Under it add:
Code:
++ zone->planet_name = strdup("None.");

14. Search int save_zone

Now scroll down and find this line:
Code:
/* Print zone header to file. */ fprintf(zfile, "#%d\n" "%s~\n" "%s~\n"

Change it to:
Code:
/* Print zone header to file. */ fprintf(zfile, "#%d\n" "%s~\n" "%s~\n" ++ "%s~\n"


Now scroll down a few line and find this:
Code:
(zone_table[zone_num].name && *zone_table[zone_num].name) ? convert_from_tabs(zone_table[zone_num].name) : "undefined",

Under it add:
Code:
++ (zone_table[zone_num].planet_name && *zone_table[zone_num].planet_name) ? zone_table[zone_num].planet_name : "None.",

Now scroll down and find this line again:

Code:
/* Print zone header to file. */ fprintf(zfile, "#%d\n" "%s~\n" "%s~\n"

Change it to:
Code:
/* Print zone header to file. */ fprintf(zfile, "#%d\n" "%s~\n" "%s~\n" ++ "%s~\n"


Now scroll down a few line and find this:
Code:
(zone_table[zone_num].name && *zone_table[zone_num].name) ? convert_from_tabs(zone_table[zone_num].name) : "undefined",

Under it add:
Code:
++ (zone_table[zone_num].planet_name && *zone_table[zone_num].planet_name) ? zone_table[zone_num].planet_name : "None.",


Hopefully, I got everything right. Remember, I'm using planet_name as an example. Change it to something you want to use.

Thanks to Gahan for pointing me into the right direction. Thanks to Vatiken for being a ghost with a pulse :).

Hey now, I still hover over the forums on a regular basis but finding the time to respond is a little difficult these days especially since I can't do it from my smartphone anymore. :P

Good work, hopefully this will help out others undertaking a similar task.

Thanks, hopefully you get some more time these days. I feel awful alone on these forums these days, besides Rumble. Hopefully I caught everything that frees planet_name.

Ahh nuts. I totally forgot to mention freeing the strings! Glad you picked up on it. My garbage collection can be flaky by times... I usually let valgrind figure it out for me =) Good guide.
