Barricade no friendly fire in KOE

[jmsngls]

Hello, how can I set my Barricade in KOE map no friendly fire by emp holder, can be cast skill like normal barri in woe.

I current use this as no friendly fire but cannot use skill on it just normal attack by enemy guild
 

if ( s_bl->type == BL_PC && t_bl->type == BL_MOB ) {
        struct map_session_data *sd = BL_CAST( BL_PC, s_bl );
        if ( ( ( (TBL_MOB*)target )->mob_id == 1905 && !strcmp( mapindex_id2name(sd->mapindex), "ra_koe" ) ) &&
            ( sd->status.guild_id == mapreg_readreg( add_str("$koegid") ) || battle_getcurrentskill(src) > 0 ) )
        return 0;
    }

I get it from annieruru KOE patch used in emperium so can't be attacked by emp holder.
