AnnieRuru 957 Posted September 23, 2020 (edited) 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 Quote -Activates a mode to ignore some packets on WoE, comming from other users -This reduce the bandwith a little bit on WoE, reducing LAG. -C = Ignore jokes and global chat messages from others. -I = Ignores Item usage from others. packetfilter: true 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 Spoiler 0.1 - plugin - proof of concept 0.2 - plugin - add sub-type flags (Self/Party/Guild/Bg/Other/Homun/Mob) - add emotion filter - fix compiler warning that doesn't display on visual studio 0.3 - plugin - add missing FILTER_CLAN flag - implement block_item type 'I' flag - fix FILTER_OTHER not working properly when the player doesn't have a party or guild - fix [C]hat type shouldn't able to filter self, since the client always shows you are talking anyway - and attempt to fix the above stupid error that doesn't show on Visual Studio 0.4 - plugin - if its not BL_PC|BL_PET|BL_HOM|BL_MER|BL_ELEM|BL_MOB immediately jump out of function for faster processing - fix sd->status.clan_id - implement block attack [A] and buff [B ] flag - don't need to use snprintf needlessly when print out the flags - just unset the flag if the SELF flag isn't supported 0.5 - plugin - fix linux compile warning `type` not being use - change useItemAckType into 0x1c8 ... hopefully no more nullpo ? - allow blocking casting animation, save more bandwidth - implement [T], [G], [D] type respectively 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 Edited November 9, 2020 by AnnieRuru 6 2 Kuroyama, Aruar, bWolfie and 5 others reacted to this Quote Share this post Link to post Share on other sites
raPalooza~ 101 Posted September 24, 2020 I've never seen this kinda of modification and i think its very neat one to maybe put as a forced settings via mapflag. Maybe the ability to only see the damage you deal and recieve, the packet would still be sent anyway because I think it's bounded to "receive damage" animaiton effect, but might reduce image cluster when maps are crowded. Maybe if passing it as 0 would reduce memory? noidea Not sure what else could we block from been area sent ^^ Gratz on the project Quote Share this post Link to post Share on other sites

I think they sent as 1 damage or something https://github.com/HerculesWS/Hercules/blob/1354b01c7a24e9ffd9ea570cbaec668721fc2a6c/conf/map/battle/client.conf#L55-L58 Quote // When set to true, the damage field in packets sent from woe maps will be set // to -1, making it impossible for GMs, Bots and Hexed clients to know the // actual damage caused by attacks. (Note 1) hide_woe_damage: true search hide_woe_damage in clif.c, the packet indeed altered to become if (skill is multiple hit)? number of hits : 0; if( battle_config.hide_woe_damage && map_flag_gvg2(src->m) ) { p.damage = damage?div:0; p.leftDamage = damage2?div:0; } else { p.damage = damage; p.leftDamage = damage2; } and yes, this modification is indeed REMOVE certain packet send to reduce server bandwidth this can only stays as plugin, and could never get into our emulator, despite how popular it is Quote Share this post Link to post Share on other sites

raPalooza~ 101 Posted September 25, 2020 @AnnieRuru I knew about the woe hiding the damage, but I was wondering if hiding everyones damage but yours would reduce bandwidth and memory. Example: If tou have 20 player hiting a worldboss for 123456789(damages are high nowadays) That wouldbe 20 x 12356789 packets sent with that value per player... If it shows only your (self) damage there would be 1 x 123456789 damage packet and 19 x -1 for the damage animation. (Hope its clear) Do you think It would improve performance? 1 AnnieRuru reacted to this Quote Share this post Link to post Share on other sites

Thanks for all the informations ^^. I think you can reverse the development process and see where the "playable" treshold stands at. For example blocking all the packet and then enabling back, while doing some kinda of perfomance test to see the hit on memory. You would probably need to setup a test environment, eg, 1,4,8,20 players in the area. But that's a lot of work xD And afterall the project already stants on a very awesome state so congratz again.

AnnieRuru 957 Posted November 5, 2020 0.2 - plugin - add sub-type flags (Self/Party/Guild/Bg/Other/Homun/Mob) - add emotion filter - fix compiler warning that doesn't display on visual studio actually there are a lot of people interested in this topic... @xJhay let me just copy paste from a PM the reason I started this topic because I received the `@packetfilter` for rathena use, and asked me to convert into plugin and upon reading it I found its very inconvenient and thus I want to rewrite it that version I receive is block based on skill ID but my plan is to block based on flags, not every skill ID entry if block by skill type listed in skill_db,conf will make the plugin future proof SkillType: { (bool, defaults to "Passive") Passive: true/false (boolean, defaults to false) Enemy: true/false (boolean, defaults to false) Place: true/false (boolean, defaults to false) Self: true/false (boolean, defaults to false) Friend: true/false (boolean, defaults to false) Trap: true/false (boolean, defaults to false) } SkillInfo: { (bool, defaults to "None") Quest: true/false (boolean, defaults to false) NPC: true/false (boolean, defaults to false) Wedding: true/false (boolean, defaults to false) Spirit: true/false (boolean, defaults to false) Guild: true/false (boolean, defaults to false) Song: true/false (boolean, defaults to false) Ensemble: true/false (boolean, defaults to false) PS: just like card seller A-Z, before I made that script every member posted on the board manually insert each card ID into each npc, until I made that SQL version which rip from SQL database, that old script still works today, make it future proof another thing to note about that version is because it block base on skill ID only, it doesn't make use of the flag of each packet on the battlefield, or I mean during woe, there are a lot of packets being sent even if its unnecessary information for example, your guild and another guild A attacking defending guild B, and your guild and guild A are not on good terms and rushing to destroy the emperium my point is, guild A attacking guild B are unnecessary in my opinion, and I don't need those packet informations but I still need to know my party/guild are under attack /// 02e1 <src ID>.L <dst ID>.L <server tick>.L <src speed>.L <dst speed>.L <damage>.L <div>.W <type>.B <damage2>.L (ZC_NOTIFY_ACT2) and I can use <src ID> and <dst ID> and check are they the same guild ? then send packet is <dst ID> my guild mates ? then send packet the rest are not important that version simply block by skill ID and from my understanding, I wouldn't know who is actually healing me when enable `@packetfilter` there are some healer who are good in healing others and some just standing there acting like a doll waiting to get hit my idea is make additional field so only filter out unneeded information when playing as crusader, my job is to defend my party, and I want all information packets send that are threatening my party when playing as assassin, I don't have to take care of guild member, I only want to assassinate the healer or dd who are actively killing the most of my guildmates etc yeah, make it highly configurable anyway read the additional information I already made this part a reality, but so far only chat and emotions are implement, skills has to do ... maybe tomorrow ... 1 xJhay reacted to this Quote Share this post Link to post Share on other sites
