I have a unique special procedures that mimics zone load. I am trying to add it to medit just as you would in Zedit.
Code:
void medit_setup_existing(struct descriptor_data *d, int rmob_num)
{
struct char_data *mob;
/* Allocate a scratch mobile structure. */
CREATE(mob, struct char_data, 1);
copy_mobile(mob, mob_proto + rmob_num);
OLC_MOB(d) = mob;
OLC_ITEM_TYPE(d) = MOB_TRIGGER;
dg_olc_script_copy(d);
/*
* The edited mob must not have a script.
* It will be assigned to the updated mob later, after editing.
*/
SCRIPT(mob) = NULL;
OLC_MOB(d)->proto_script = NULL;
OLC_PROC(d) = OLC_MOB(d)->mob_specials.func;
}
Code:
case MEDIT_PROC_MENU:
switch (tolower(*arg)) {
case 'q':
medit_disp_menu(d);
return;
case 'n':
/* New entry. */
if (OLC_PROC(d)[0].command == '~') {
/* first command */
if (new_mob_proc(OLC_MOB(d), 0) && start_change_procs(d, 0)) {
medit_spec_proc_assign(d);
OLC_SAVE(d) = 1;
return;
}
}
write_to_output(d, "What number in the list should the new command be? : ");
OLC_MODE(d) = MEDIT_NEW_ENTRY;
return;
Code:
case MEDIT_NEW_ENTRY:
/* Get the line number and insert the new line. */
pos = atoi(arg);
if (isdigit(*arg) && new_mob_proc(OLC_MOB(d), pos)) {
if (start_change_procs(d, pos))
medit_spec_proc_assign(d);
OLC_SAVE(d) = 1;
} else
medit_disp_spec_menu(d);
return;
Genmob.c
Code:
/* Error check user input and then add new (blank) command. */
int new_mob_proc(struct char_data *mob, int pos)
{
int subcmd = 0;
struct spec_proc new_com;
/* Error check to ensure users hasn't given too large an index. */
while (mob->mob_specials.func[subcmd].command != '~')
subcmd++;
if (pos < 0 || pos > subcmd)
return 0;
/* Ok, let's add a new (blank) command. */
new_com.command = 'N';
add_proc_to_list(&mob->mob_specials.func, &new_com, pos);
return 1;
}
My issue is that the minute i add a new command it crashes the game. I believe the reason to be because i impact the currently loaded mobile with that procedure. I am stuck because i want to load a copy of the procedure list, and edit it, than remove it from the mob_proto than add the updated one than update the in game mobile.
i believe that i corrupt the first memory block, which than crashes the game when the mobile goes through its live procedure calls. The line in red below should have been ch->mob_specials.func[0].func = Mob armies but as you can see it is corrupted.
