@partybuff / @spb

[cumbe11]

Here is this change?
 
 
 
@partybuff (@spb) can display party member's special buffs in party list (Alt+Z)
Buffs are:
Quote

B - Blessing
A - Agility Up
F - Full Chemical Protection
S - Soul Link
+ - Devotion

Look like
[BAFS+]Player name

 

[AnnieRuru]

even if this is possible, there is a client restriction which disallow to display player name longer than 23 characters ...
and the color has to be client reverse engineer ...
 
means, no, this also has to do client side modification
 
but if not display in the Alt+Z, but with a message command
then this can even done with scripting alone, with getstatus script command

-  script  jsfkjsdf  FAKE_NPC,{OnInit:  bindatcmd "psc", strnpcinfo(0)+"::Onaaa";  end;Onaaa:  .@pid = getcharid(1);  if ( !.@pid ) {    dispbottom "you don't have a party to use this command";    end;  }  getpartymember .@pid, 1;  getpartymember .@pid, 2;  .@origin = getcharid(3);  for ( .@i = 0; .@i < $@partymembercount; ++.@i ) {    if ( isloggedin( $@partymemberaid[.@i] , $@partymembercid[.@i] ) ) {      attachrid $@partymemberaid[.@i];      .@buff$ = "";      if ( getstatus(SC_BLESSING) ) .@buff$ += "B";      if ( getstatus(SC_INC_AGI) ) .@buff$ += "A";      if ( getstatus(SC_PROTECTWEAPON) && getstatus(SC_PROTECTSHIELD) && getstatus(SC_PROTECTARMOR) && getstatus(SC_PROTECTHELM) ) .@buff$ += "F";      if ( getstatus(SC_SOULLINK) ) .@buff$ += "S";      if ( getstatus(SC_DEVOTION) ) .@buff$ += "+";      .@display$[.@c++] = "["+ .@buff$ +"] "+ strcharinfo(0);    }  }  attachrid .@origin;  for ( .@i = 0; .@i < .@c; ++.@i )    dispbottom .@display$[.@i];  end;}

There's a mod like this from rAthena which is from Lilit's Mod.

Name can be modified via clif.c, hooking appropriate functions..(And trimming names if they reach > 23 char, thats what they do)

 

[AnnieRuru]

ok, let's analyze the packet

clif_party_member_info

/// Adds new member to a party.

/// 0104 <account id>.L <role>.L <x>.W <y>.W <state>.B <party name>.24B <char name>.24B <map name>.16B (ZC_ADD_MEMBER_TO_GROUP)

23 characters for name, 23 characters for map name

hmm ... if we replace the map name with buff ... hehe ... sounds fun

clif_party_info

/// Sends party information (ZC_GROUP_LIST).

/// 00fb <packet len>.W <party name>.24B { <account id>.L <nick>.24B <map name>.16B <role>.B <state>.B }*

/// role:

/// 0 = leader

/// 1 = normal

/// state:

/// 0 = connected

/// 1 = disconnected

clif_party_xy

/// Updates the position of a party member on the minimap (ZC_NOTIFY_POSITION_TO_GROUPM).

/// 0107 <account id>.L <x>.W <y>.W

clif_party_hp

/// Updates HP bar of a party member.

/// 0106 <account id>.L <hp>.W <max hp>.W (ZC_NOTIFY_HP_TO_GROUPM)

so ... there is no packet to update the party member's status in Alt+Z bar

clif_parse_LeaveParty

/// Request to leave party (CZ_REQ_LEAVE_GROUP).

clif_parse_RemovePartyMember

/// Request to expel a party member (CZ_REQ_EXPEL_GROUP_MEMBER).

the one trick that I can think off, is sending a packet to leave player's party and invite back with a fake name

but I wonder doing this will have message on the chat log ?

... hmm ... ask a client translation team, maybe they know where is the english file at

 

[Dastgir]

void clif_party_info -> memcpy(WBUFP(buf,28+c*46+4), m->name, NAME_LENGTH); 
Just modify m->name before using memcpy.. and that will show change in party window.

Edit: In chat log, they will have normal name, just party window will be edited.

 

[cumbe11]

 

[Garr]

Hmm. But that will also need additional calls to this if status will get changed. Because iirc by default party info changes when player either logs off/on or changes map. Also, may change character name limit to 17 to avoid name cutting (most nicknames are under 12~15 characters anyway).

I thought about that,

there is a bug, when the player JUST login for the 1st time in that party ( party just loaded )
your name will appear twice in the party window

but will disappear when apply a buff ... or another party member login

and, when apply a buff, it really does show the [b____] for the party member name


I guess, have to do something like @showbuff atcommand, to make this bug disappear
it also has the advantage to show it or not to show it
... and this is harder to do than I thought
try continue tomorrow, I have to sleep now =.=

[Functor]

there is a bug, when the player JUST login for the 1st time in that party ( party just loaded )

your name will appear twice in the party window

Also we can see this bug, when someone enters to the party.
 
It is caused by sending of 0x1E9 packet, which adds one specific party member to the list on the client side.
 
To fix bug of this plugin, we can disable sending of this packet.
 
Because in any case server always sends full list of party members in 0xFB packet.
before:

HPExport void plugin_init (void) {

add:

void clif_party_member_info_overload(struct party_data* p, struct map_session_data* sd)
{
return;
}


after:

HPExport void plugin_init (void) {

add:

clif->party_member_info = &clif_party_member_info_overload;

in ACMD(showbuff) in line 275 you show error message and p is NULL, and after call clif->party_info(p), this call your overloaded function clif_party_info_overload, and here it validate parameter for NULL and show error message.
