Packet Parsing & Handling

[akanieski]

Ello!

Max had noted that the party leader flag is not being sent to the client. I assume this is why the leader of a party cannot click the "Make Leader" button.

I think either the F_CHARACTER_INFO or the F_GROUP_STATUS packets update this flag.. I tried tweaking the F_CHARACTER_INFO packet in any unknown byte spots. But couldn't find anything that seemed to mark the party leader.

I think that this flag is being sent over in the F_GROUP_STATUS packet. I also see WarEmu has nothing to handle/send this packet to the client..

Does anyone have any info about F_GROUP_STATUS?

[akanieski]

Does this mean anything to anyone who understands the packet structures? I'm looking for more info on F_GROUP_STATUS

Code: Select all

public List<Player> Members = new List<Player>();
 
        public void Update()
        {
            Log.Debug("Group", "Updating Group");
 
            if(Leader == null)
                SetLeader(Members.First());
 
            PacketOut Out = new PacketOut((byte)Opcodes.F_CHARACTER_INFO); // 03 68 BE
            Out.WritePacketString(@"|06 02 87 22 04 9C E4 6C 0F 19 0F 28 00 |.........l...(.|

Look at the function called SendWhosLeader. It most likely is missing some kind of opcode that is sent to the client to set the group leader visually.

Ooo

You can also try working from client side. Group UI code is in interface\ea_groupwindow\source\groupwindow.lua. Group leader is set by calling BroadcastEvent( SystemData.Events.GROUP_SET_LEADER ). I would simply try calling that manually with custom addon and see what packet is sent to the server. Then search all the packet logs for similar packet.

My /Interface/ folder only has /AddOns/ in it?

[akanieski]

I found this lua on the web. (http://wardiff.googlecode.com/svn/trun ... indow.lua)

You need to unpack the interface.myp in the WAR folder.
