how to disable @warp when died?

[Blazing Spear]

This is my atcommand.c

/*==========================================
* @rura, @warp, @mapmove
*------------------------------------------*/
ACMD_FUNC(mapmove)
{
char map_name[MAP_NAME_LENGTH_EXT];
unsigned short mapindex;
short x = 0, y = 0;
int m = -1;

nullpo_retr(-1, sd);

memset(map_name, '\0', sizeof(map_name));

if (!message || !*message ||
(sscanf(message, "%15s %hd %hd", map_name, &x, &y) < 3 &&
sscanf(message, "%15[^,],%hd,%hd", map_name, &x, &y) < 1)) {

clif_displaymessage(fd, "Please, enter a map (usage: @warp/@rura/@mapmove <mapname> <x> <y>).");
return -1;
}

if( battle_config.pvpmode_nowarp_cmd && sd->state.pvpmode )
{
clif_displaymessage(sd->fd,"You can not use @go while on PVP Mode.");
return -1;
}

mapindex = mapindex_name2id(map_name);
if (mapindex)
m = map_mapindex2mapid(mapindex);

if (!mapindex) { // m < 0 means on different server! [Kevin]
clif_displaymessage(fd, msg_txt(1)); // Map not found.
return -1;
}

if ((x || y) && map_getcell(m, x, y, CELL_CHKNOPASS))
  { //This is to prevent the pc_setpos call from printing an error.
clif_displaymessage(fd, msg_txt(2));
if (!map_search_freecell(NULL, m, &x, &y, 10, 10, 1))
x = y = 0; //Invalid cell, use random spot.
}
if (map[m].flag.nowarpto && !pc_has_permission(sd, PC_PERM_WARP_ANYWHERE)) {
clif_displaymessage(fd, msg_txt(247));
return -1;
}
if (sd->bl.m >= 0 && map[sd->bl.m].flag.nowarp && !pc_has_permission(sd, PC_PERM_WARP_ANYWHERE)) {
clif_displaymessage(fd, msg_txt(248));
return -1;
}

if( !pc_get_group_level(sd) && DIFF_TICK(gettick(),sd->canlog_tick) < 5000 ) {
clif_displaymessage(fd,"@warp cannot be issued since you were into battle recently");
return -1;
}

if (pc_setpos(sd, mapindex, x, y, CLR_TELEPORT) != 0) {
clif_displaymessage(fd, msg_txt(1)); // Map not found.
return -1;
}

if( pc_isdead(sd) )
{
clif_displaymessage(fd, "You cannot use this command when dead.");
return -1;
}

clif_displaymessage(fd, msg_txt(0)); // Warped.
return 0;
}
