Oid structure

[lion228]

hello how would i make the Oid packet structure reversed ? it makes the Oid from this sturcture
Out.WriteUInt16(Oid);

i want to add another Out.WriteUInt16(Oid); but how i make it so it reverses the Oid

example Out.WriteUInt16(Oid); makes random Oid say = 2622 which is = 0A 3E
so how i make is reverse the Oid random so it be = 3E 0A

0A 3E 00 00 00 00 3E 0A

The OID is something that should be related to an object (item, mob, player, npc...)

You can simply recreate this object and affect it the OID you read from packet.

[lion228]

yes its for npc. the stucture is for packet (03 FC 00 00 03 FC) what i use for the last structure so it reverces it for 03 FC Out.WriteUInt16(Oid); = 03 FC
Out.WriteByte(0); 00
Out.WriteByte(0); 00

Out.WriteUInt16() 03 FC ???????
03 FC 00 00 03 FC

Is this for DOL or WAR?

[lion228]

yes war the packet above is wrong this is the correct one with the reversed Oid = FC 03
03 FC 00 00 FC 03

So you want to send low-endian not big-endian?

I think you want something like
ushort originalOID = 12341;
Out.WriteByte(originalOID && 0xFF);
Out.WriteByte(originalOID >> 8 && 0xFF);

But tbh I always get the bitwise operators wrong so I would double check that.

Also - Please stop asking questions about another game/emulator without explicitly saying its for that game/emulator. You have a million posts where you ask about packets and fail to mention they are for WAR every time. And once again I emphasise this is not a forum for WAR

[lion228]

ok sorry and thanks i will try that. yeh i dont say its for war because i know you dont like war and just needed the info on how to send it reversed

[Dinberg]

It's not that we don't like WAR, its just that these forums are for a different project

Did the code work?

[lion228]

the packet structure is this

Out.WriteUInt16(Oid);
Out.WriteByte(0);
Out.WriteByte(0);
Out.WriteUInt16(0);

The orignal sniffed packet is 0A 3E 00 00 3E 0A
but when useing sniffer i get this 0A 3E 00 00 00 00 so 3E 0A is the Oid so need the last structure Out.WriteUInt16(0); to reverse it .so when i use sniffer it should look like this 0A 3E 00 00 3E 0A so the 0A 3E is been reversed on the last 2 bytes
