Confused about the spawn entity packet
So I wanted to update the spawn entity packet from Hybrid's source (5135 -> 5165)
Code:
public unsafe struct SpawnEntityPacket
{
[FieldOffset(0)]
public ushort Size;
[FieldOffset(2)]
public ushort Type;
[FieldOffset(4)]
public uint Model;
[FieldOffset(8)]
public uint UID;
[FieldOffset(12)]
public ushort GuildID;
[FieldOffset(15)]
public GuildRank GuildRank;
[FieldOffset(16)]
public ulong StatusFlag;
[FieldOffset(24)]
public uint HelmetID;
[FieldOffset(28)]
public uint HorseID;
[FieldOffset(32)]
public uint ArmorID;
[FieldOffset(36)]
public uint LeftHandID;
[FieldOffset(40)]
public uint RightHandID;
[FieldOffset(48)]
public ushort Hitpoints;
[FieldOffset(50)]
public ushort Level;
[FieldOffset(52)]
public ushort Hairstyle;
[FieldOffset(54)]
public ushort X;
[FieldOffset(56)]
public ushort Y;
[FieldOffset(58)]
public ConquerAngle Facing;
[FieldOffset(59)]
public ConquerAction Action;
[FieldOffset(64)]
public byte Reborn;
[FieldOffset(65)]
public ushort LevelPotency;
[FieldOffset(70)]
public int OtherPotency;
[FieldOffset(84)]
public NobilityID Nobility;
[FieldOffset(88)]
public ushort ArmorColor;
[FieldOffset(90)]
public ushort ShieldColor;
[FieldOffset(92)]
public ushort HeadColor;
[FieldOffset(110)]
public byte StringsCount;
[FieldOffset(111)]
public byte NameLength;
[FieldOffset(112)]
public fixed byte Strings[24];
public void SetName(string value)
{
string m_Name = value;
if (m_Name.Length > 15)
m_Name = m_Name.Substring(0, 15);
Size = (byte)(0x70 + m_Name.Length);
StringsCount = 1;
NameLength = (byte)m_Name.Length;
fixed (byte* ptr = Strings)
{
MSVCRT.memset(ptr, 0, 24);
value.CopyTo(ptr);
PacketBuilder.AppendTQServer(ptr + NameLength, 8);
}
}
public static SpawnEntityPacket Create()
{
// Size and TQServer are appended when SetName() is called.
SpawnEntityPacket packet = new SpawnEntityPacket();
packet.Type = 0x271E;
return packet;
}
But there are a few things confusing me:
[FieldOffset(48)]
public ushort Hitpoints;
[FieldOffset(65)]
public ushort LevelPotency;
[FieldOffset(70)]
public int OtherPotency;
According to the packet wiki (  ) there's no such thing as HP, LevelPotency and OtherPotency in the packet yet there is in Hybrid's.
So how should I update this?

Depends which your spawning, the packet wiki only contains the offsets for the character spawning, monster spawning uses offsets which are also used by characters but in a different way. HP, Level Potency and Other Potency are only ever used, to my knowledge for monsters, since they display these details, characters do not.

I thought that Level and Other Potency were used for this:
And it doesn't really explain why those values aren't there in the 5165 version.

as korv said. not all values for every use of packets are posted on his wiki. spawn entity can be used for a number of things and therefor some fields will be used in different ones. IE; hp when spawning mobs or the bp calc as mentioned.
Just run through the diff offsets yourself using a cmd and you'll be able to structure it easily enough.

Your confusing 2 systems, the spawn packet does not relate to that.

Hitpoints refers to a monsters hitpoints (as monters are spawned with given HP). LevelPotency, and OtherPotency is visible when you view a persons equipment. I'd assume this is "LevelPotency":
Quote:
and OtherPotency simply isn't documented in this structure (so you'd have to guess & test to find out where it is, it's likely between 69-88).
So, you'll have to find the new offsets for OtherPotency, and Hitpoints. You can base them off my current offsets, and,
Essentially, this hints the value is either at the offset specified or above it.

Isn't this the character level?

public ushort Level;

Uh, there's two "level" offsets in the spawn packet. One is for monsters (it's how the client determines whether a monster is black name or redname)... and the other one is for potency (like, when you view someone's equipment, it says their level).

Spawn Entity - Equipment (5273)
06/29/2010 - CO2 Private Server - 9 Replies
The Entity Spawn packet (10014) is sent by the server and contains values to spawn the character, such as the equipment id's.
Now when logging packets, I never once see this packet sent, am I missing something?
I need to log it to get the correct offsets of the equipment id's, since my equipment isn't showing up on my character (looks naked, but if you go in the stats it shows the equipment is equipped).
So does anyone know if TQ changed some shit around? Thanks.
(PS, this is for client...
