Well, i get this when i was googling, i don't know exactly what it does, i understand it more or less. But, this inject the token on walker?

 

 

 

 

 

 

const

EnterWorldPacket = HStr('6B000300000000000000000000000000000000C9BCF2A7665A0B9836A5BD89ED7FE4D76B49E29FEF76EBCEA3FAF4BF0C64A3B4A4CEDCC6083E6EEA45CAD3FE881387B8062C96F09B1E8EBCC69B98C86316CFD0290000000000000000000000000000000000000000000000');

 

var

buf: string;

 

BEGIN

if length(_gBuff) < 3 then gBlockPacket;

if (not _gFromServ) and StrCmp(_gBuff[3],#$81) then gBlockPacket; // GMlist

 

// EnterWorld (ia iieiia ?aoaiea)

if (not _gFromServ) and StrCmp(_gBuff[3],#$03) then

_gOutBuff := EnterWorldPacket;

 

if (not _gFromServ) and StrCmp(copy(_gBuff,1,3),HStr('3900 08')) then // RequestAuthLogin

_gOutBuff := #$35 + copy(_gBuff,2,length(_gBuff)-5);

 

if _gFromServ and StrCmp(_gBuff[3],#$15) then gSys.EnSEndS(HStr('0500D00800')); // RequestManorLst

END.

Some kind of server-deffence cheat or simply server-client protocol fixes.

 

Block packet "gm-list" (for example l2w send it when entering world? so can be easy detected by administrators); modify 2 packets (request login and get manor list). All modifications are applied to packets, that are send from client to server.

 

Nothing difficult, but you have to know packets values and structure.

 

BTW. WC PPC scripts can be applied with any kind of client (bot or original client). No differences.

I'm don't know packets on interlude. But, if you interested, you can compare packets in script with packets implemented in l2j-interlude server. L2j is opensouce, so you can simply find all packets in code.
