Network.Flags

[jaynigs]

Ive been trying for the last 2 hours to change the supported features within the core dependant on the client expansion.. The problem i face is that the Network.Flags are not set until the player logs in with a character, so i cannot seem to test if the player uses Mondains Legacy etc at server login...


i have Highlighted in bold where the Netstate flags are set.


PacketHandlers.cs

	public static void PlayCharacter( NetState state, PacketReader pvSrc )
		{
			pvSrc.ReadInt32(); // 0xEDEDEDED

			string name = pvSrc.ReadString( 30 );

			pvSrc.Seek( 2, SeekOrigin.Current );
			int flags = pvSrc.ReadInt32();
			pvSrc.Seek( 24, SeekOrigin.Current );

			int charSlot = pvSrc.ReadInt32();
			int clientIP = pvSrc.ReadInt32();

			IAccount a = state.Account;

			if ( a == null || charSlot < 0 || charSlot >= a.Length )
			{
				state.Dispose();
			}
			else
			{
				Mobile m = a[charSlot];

				// Check if anyone is using this account
				for ( int i = 0; i < a.Length; ++i )
				{
					Mobile check = a[i];

					if ( check != null && check.Map != Map.Internal && check != m )
					{
						Console.WriteLine( "Login: {0}: Account in use", state );
						state.Send( new PopupMessage( PMMessage.CharInWorld ) );
						return;
					}
				}

				if ( m == null )
				{
					state.Dispose();
				}
				else
				{
					if ( m.NetState != null )
						m.NetState.Dispose();

					NetState.ProcessDisposedQueue();

					state.BlockAllPackets = true;

					state.Flags = flags;

and this is where i need them..


PacketHandlers.cs

		public static void GameLogin( NetState state, PacketReader pvSrc )
		{
			if ( state.SentFirstPacket )
			{
				state.Dispose();
				return;
			}

			state.SentFirstPacket = true;

			int authID = pvSrc.ReadInt32();

			if ( !IsValidAuthID( authID ) )
			{
				Console.WriteLine( "Login: {0}: Invalid client detected, disconnecting", state );
				state.Dispose();
				return;
			}
			else if ( state.m_AuthID != 0 && authID != state.m_AuthID )
			{
				Console.WriteLine( "Login: {0}: Invalid client detected, disconnecting", state );
				state.Dispose();
				return;
			}
			else if ( state.m_AuthID == 0 && authID != state.m_Seed )
			{
				Console.WriteLine( "Login: {0}: Invalid client detected, disconnecting", state );
				state.Dispose();
				return;
			}

			string username = pvSrc.ReadString( 30 );
			string password = pvSrc.ReadString( 30 );


			int flags = pvSrc.ReadInt32();


			GameLoginEventArgs e = new GameLoginEventArgs( state, username, password );

			EventSink.InvokeGameLogin( e );

			if ( e.Accepted )
			{
				state.CityInfo = e.CityInfo;
				state.CompressionEnabled = true;


				if ( Core.AOS )
					state.Send( SupportedFeatures.Instantiate( state.Account, flags ) );

				state.Send( new CharacterList( state.Account, state.CityInfo ) );
			}
			else
			{
				state.Dispose();
			}
		}

Since Ea/Osi use this ability, there must be some packet info i could use to set the Netstate.Flags earlier. Or, another way to detect the expansion type from ClientVersion info?

Thanks for reading

They handle it via their account system.

Thanks for reply.

Yes and no, the accounts are tagged with what version you are permitted to use, but if you dont update your client, you cannot create an elf for example.

Thanks again for the reply.

It seems the packet being read by these 2 methods are different packets..

Packet 0x5D is PlayCharacter
Packet 0x91 is GameLogin

[jaynigs]

After some experiments, they arent the same packet info, gamelogin packet contains only authID and user name and pass strings, i could find no such info in this packet pertaining to client expansion type, or any other client info at all for that matter.

This might help determine whats in the packets...

I still believe the flags which is based on the client, is the same information.

Ah, i may be to blame there, my apologies, i added the overload flags to that line myself as i was experimenting with something.

Base runuo is just,,

if ( Core.AOS )
					state.Send( SupportedFeatures.Instantiate( state.Account ) );
