No more Work in Progress, Please report if there are any bug Download: 1.0a [Complete] plugin What is `@packetfilter` ? `@packetfilter` is a custom mod originate from eamod https://github.com/zephyrus-cr/eamod/blob/master/Servers/rAthena/conf/groups.conf#L418-L422 it can actually reduce lag on your live server during woe depends on how many players activate it it totally depends on the player's side, community effort that every player should together turn on the `@packetfilter` to reduce massive lag during woe this modification is actually very famous and there are members willingly to pay for it https://rathena.org/board/topic/121200-packetfilter-battleinfo/ https://rathena.org/board/topic/123203-battleinfo-packetfilter/ https://rathena.org/board/topic/111797-packetfilter-zepyhrus-ramod/ https://rathena.org/board/topic/79995-buy-noactnodelay-partybuff-src-as-it-was-on-pro-ro-or-packetfilter/ this `@packetfilter` is unlike the one you are having, or that is circulating on rathena forum this one has been written entirely from scratch and added some other flags that the original don't for example, `@packetfilter COHM EOHM` allow block normal chat and emotion from non-related players, pets, homunculus and monsters but this doesn't block normal chat from party/guild members a full list of flags are C = ignore normal Chat, including Dancer's scream, Bard's frost joke, and pet's talk (pet start to talk when intimacy > 900) E = ignore emotion, including monster and pet emotion (but NOT pet performance) I = ignore Item use effect A = ignore normal Attack animation (based on receiving side), your own attack animation are always shown B = Buffing skill animations (based on receiving side), your own casting animation are always shown S = Status effect T = offensive single Target skill/spell animations (based on receiving side), your own casting animation are always shown G = Ground based skills (eg:storm gust), your own casting animation are always shown M = Music dance/songs from Bard/Dancer D = Direction. Recommend filter on Party/Guild type and not enemies. Highly Recommend for supportive type Class. after the Main type, also support additional flags S = Self P = Party G = Guild B = Battleground C = Clan O = Other players, none of the above H = Homunculus/pets/elementals/mercenary and player's @summon M = Monsters Why This plugin doesn't block Kaite or Energy Coat ? 2 reasons No.1 - currently there is a bug with plugin, struct packet_spawn_unit *p = (struct packet_spawn_unit*)RBUFP(buf, 0); this line will throw error on Linux so no choice, maybe I'll make a bug report this bug also has been reported on Dastgir's `@noview` No.2 - just set p->virtue = 0; isn't really blocking the packet this goes against the very principle of this plugin, which is NOT send certain packet to the client OPT3 (including OPT3_KAITE | OPT3_ENERGYCOAT | OPT3_SOULLINK) is part of the idle_unitType, unit_walkingType and spawn_unitType function and blocking those 3 packet entirely is stupid in case you don't understand, look under clif_set_unit_walking and clif_set_unit_idle function inside src\map\clif.c file p.GUID = g_id; p.GEmblemVer = status->get_emblem_id(bl); p.honor = (sd) ? sd->status.manner : 0; // p.virtue = (sc) ? sc->opt3 : 0; <-- change this line p.virtue = 0; p.isPKModeON = (sd && sd->status.karma) ? 1 : 0; p.sex = vd->sex; Note: about [D]irection type packet try add a ShowDebug inside clif->send src/map/clif.c | 1 + 1 file changed, 1 insertion(+) diff --git a/src/map/clif.c b/src/map/clif.c index ab3c4422a..9e245f335 100644 --- a/src/map/clif.c +++ b/src/map/clif.c @@ -450,6 +450,7 @@ static bool clif_send(const void *buf, int len, struct block_list *bl, enum send return true; } +ShowDebug("source:%s buf:0x%x send_target:%d\n", (sd != NULL)? sd->status.name : "NULL", RBUFW(buf, 0), type); switch(type) { case ALL_CLIENT: //All player clients. iter = mapit_getallusers(); you will find 0x9c is being send repeatedly on every attack and every skill cast , getting attack etc this direction update packet isn't just send by Shift-click, but also including all the actions above this packet is very spam-able and I think can be safely block on party/guild/clan/bg flags for supportive class, I also think can block all of them since supportive class doesn't need information from enemies

I found this in src\map\packet_struct.h struct PACKET_ZC_USE_ITEM_ACK { int16 packetType; int16 index; #if PACKETVER_MAIN_NUM >= 20181121 || PACKETVER_RE_NUM >= 20180704 || PACKETVER_ZERO_NUM >= 20181114 uint32 itemId; uint32 AID; #elif PACKETVER >= 3 uint16 itemId; uint32 AID; #endif int16 amount; uint8 result; } __attribute__((packed)); so client version 20181121 below uses `RBUFL(buf, 6)`, anything above use `RBUFL(buf, 8)` 1.0 - plugin - introduce type [D], direction packet, and existing Dance/songs move to type `[M]usic` - no longer use nested IF-ELSE, use switch statement on the packet header for faster read speed - fix [I.]tem type throw nullpo error on 2018 client - add Caution as a warning that certain packet filter wont work correctly and I guess this is finally over time to mention everyone that has PM me about this project @raPalooza~ @Azhura @freezing1 @xJhay @Kuroyama @fiction @Skyzone @cusco ? <-- from discord
