hi,

before posting something like that,
Please search in forum threads. there's source code of your request

In the login screen is a button to choose the server u want to play on. If u click on it u will receive your A101. Before receiving it, you will get the 6101 (S->C). Now, just send C->S 6101 (without data) and u will get the A101 as response.
Not hard at all, hm? Just need to know how to use an analyzer.

I didnt want to create a new topic and cause spam.
Now im trying to find how hpmp update packets are built
i tried already but couldn't find anywhere and there is no any clear guide for it.
Thank you , sarkolata

You can take lesderid's login server documentation that should do the trick it's stickied btw.

Owh and something which isn't told in his documentation. the server list of isro (idk if it's also in another version) is a bit different since the amount of players is in a float so 0.00 = server empty 0.50 = half full and 1 = server full.
in some other version or older ones the capacity was a word or dword I can't remember and there are 2 of them so the first one is the current amount of players and the second one the max amount of players.

Keep this in mind if you get strange values

HP/MP Update

AD 8A 4E 00		object id
04			type 1
02			type 2
FC 00 00 00		new value 

If type 2 = 3 or 5, then a trailing dword is added for MP value.


Type 1:

10			increase
01			hp decrease
04			mp decrease

Type 2:

01			hp
02			mp
03			hp & mp
04			?
05			mob hp & mp

I have the same. I couldn't understand it from there..

Owh sorry I thought your were talking about the server list xD
kinda confusing title.

but if you want the hp and mp of your character and follow the updates you need to parse the 0x3013 or 0x34e5 packet if i am correct at least the big character data packet. one of the first bytes is the hp and mp and the stats packet which comes a bit after that one (idk the opcode) contains the current hp and mp.

now you need to do something which changes your hp like casting a pot and check the packets you logged to find the correct one which contains the hp and mp and with edx silkroad loader it'll already be parsed so all you need to do is read the packet.

Well, I didn't test it yet so there could be some mistakes, but you could try something like that (no C&P-Code):

PHP Code:

int objectid = packet.read_dword
byte type1 = packet.read_byte //increase or decrease, unnecessary atm...
byte type2 = packet.read_byte //hp or mp or hp&mp

switch type2
{
case 1 //hp
if objectid = me.objectid then
me.currenthp = packet.read_dword
elseif moblist.contains(objectid) then
moblist(objectid).currenthp = packet.read_dword
end if
case 2 //mp
if objectid = me.objectid then
me.currentmp = packet.read_dword
end if
case 3 //hp & mp
if objectid = me.objectid then
me.currenthp = packet.read_dword
me.currentmp = packet.read_dword
end if
}

Pservers doesnt support edx loader
@xKraizy
I will check it out. thanks

Fixed it finally... Here if it helps you ;

PHP Code:

  Dim ms As New MemoryStream(data)
        Dim bn As New BinaryReader(ms)
        Dim objectid As UInt32 = bn.ReadUInt32
        Dim i As Byte = bn.ReadByte
        Dim type As Byte = bn.ReadByte

        Select Case CByte((type - 1))
            Case 0
                hpcur = bn.ReadUInt32
                Exit Select
            Case 1
                mpcur = bn.ReadUInt32
                Exit Select
            Case 2
                hpcur = bn.ReadUInt32
                mpcur = bn.ReadUInt32
                Exit Select
            Case 3
                Dim b As Byte = bn.ReadByte
                Exit Select
        End Select

Why do u do type -1? Just do type and:
1: Char.HP
2: Char.MP
3: Char.HP & Char.MP
4: dunno
5: Mob.HP (u will need it later if u r gonna make a bot)
