Adding new mapflag
Introduction¶
When scripting, or creating custom automated events, you may wish to add your own custom mapflags. In order to do so, you'll need to complete some source edits. This article will explain how.
This article was originally created by TecnoCronus on the eAthena forums.
Adding your mapflag¶
Open /src/map/map.h¶
Find:
unsigned src4instance : 1; // To flag this map when it's used as a src map for instances
Add below:
unsigned mymapflag : 1;
Open /src/map/map.c¶
Find:
} else if (!strcmpi(flag,"nocashshop")) {
if( state && map->list[m].flag.nocashshop )
;/* nothing to do */
else {
if( state )
map_zone_mf_cache_add(m,"nocashshop\toff");
else if( map->list[m].flag.nocashshop )
map_zone_mf_cache_add(m,"nocashshop");
}
}
Add below:
else if( !strcmpi(flag,"mymapflag")) {
if( state && map->list[m].flag.mymapflag )
; /* nothing to do */
else {
if( state )
map_zone_mf_cache_add(m,"mymapflag\toff");
else if( map->list[m].flag.mymapflag )
map_zone_mf_cache_add(m,"mymapflag");
}
}
Open /src/map/script.h¶
Find:
MF_NOCASHSHOP
Replace with:
MF_NOCASHSHOP,
MF_MYMAPFLAG
Open /src/map/script.c¶
Find:
case MF_GUILDLOCK: script_pushint(st,map->list[m].flag.guildlock); break;
Below add:
case MF_MYMAPFLAG: script_pushint(st,map->list[m].flag.mymapflag); break;
Find:
case MF_GUILDLOCK: map->list[m].flag.guildlock=1; break;
Below add:
case MF_MYMAPFLAG: map->list[m].flag.mymapflag=1; break;
Find:
case MF_GUILDLOCK: map->list[m].flag.guildlock=0; break;
Below add:
case MF_MYMAPFLAG: map->list[m].flag.mymapflag=0; break;
Open /src/map/npc.c¶
Find:
else if (!strcmpi(w3,"guildlock"))
map->list[m].flag.guildlock=state;
Below add:
else if (!strcmpi(w3,"mymapflag"))
map->list[m].flag.mymapflag=state;
Open /db/const.txt¶
Find:
mf_guildlock45
Below add:
mf_mymapflag46
Listing your mapflag in atcommands¶
Open /src/map/atcommand.c¶
Find:
if (map->list[m_id].flag.nomemo)
strcat(atcmd_output, msg_txt(1064)); // NoMemo |
Below add:
if (map->list[m_id].flag.mymapflag)
strcat(atcmd_output, "mymapflag |");
Find:
CHECKFLAG(nocashshop);
Below add:
CHECKFLAG(mymapflag);
Find:
SETFLAG(nocashshop);
Below add:
SETFLAG(mymapflag);
Find:
clif->message(sd->fd,"guildlock, src4instance, notomb, nocashshop");
Replace it with:
clif->message(sd->fd,"guildlock, src4instance, notomb, nocashshop, mymapflag");
Conclusion¶
Recompile and you can now set "mymapflag" to any value. Remember, you can rename the mapflag to whatever, and later use the flag option anywhere else in your source code.
