Unexpected msgtype 8

jingyiwang

I am working on my own version of mmo server.

I got the operation request and response communication working between client and server e.g. for a operation to enter the game world.

Now I am struggling with a simple Peer.SendMessage method. On the Unityclient side I receive the message but cannot read it. I get the following error:

ERROR: unexpected msgType 8
UnityEngine.Debug:Log(Object)
JYW.ThesisMMO.UnityClient.Assets.Scripts.Networking.ServerPeerListener:DebugReturn(DebugLevel, String) (at Assets/Scripts/Networking/ServerPeerListener.cs:15)
ExitGames.Client.Photon.<>c__DisplayClass2:b__0()
ExitGames.Client.Photon.EnetPeer:DispatchIncomingCommands()
ExitGames.Client.Photon.PhotonPeer:DispatchIncomingCommands()
ExitGames.Client.Photon.PhotonPeer:Service()
JYW.ThesisMMO.UnityClient.Assets.Scripts.Networking.Game:Update() (at Assets/Scripts/Networking/Game.cs:37)

What is msgType 8? I haven't found anything in the api docs.


I send the message after a client entered the game world. I send a message to all other clients which are already in the game world like this:

Server code:

Code from the game world:

        private Channel<Message> m_MessageChannel = new Channel<Message>();
        internal void AddEntity(PlayerEntity entity) {
            log.DebugFormat("Adding entity with name: " + entity.Username);
            m_Entities[entity.Username] = entity;

            var newPlayerEvent = new NewPlayerEvent();
            newPlayerEvent.Username = entity.Username;
            newPlayerEvent.Position = entity.Position;
            IEventData eventData = new EventData((byte)EventCode.NewPlayer, newPlayerEvent);
            var sendParameters = new SendParameters { Unreliable = false, ChannelId = 0 };
            var message = new Message(eventData, sendParameters);
            m_MessageChannel.Publish(message);
        }

Peer's op handler:
(SendMessage is subscribed to m_MessageChannel of the game world.)

        private void SendMessage(Message message) {
            m_Peer.SendMessage(message.eventData, message.sendParameters);
        }

The message struct for IChannel:

namespace JYW.ThesisMMO.MMOServer {
    using Photon.SocketServer;
    internal struct Message {
        internal Message(IEventData eventData, SendParameters sendParameters) {
            this.eventData = eventData;
            this.sendParameters = sendParameters;
        }
        internal IEventData eventData;
        internal SendParameters sendParameters;
    }
}

The data contract:

namespace JYW.ThesisMMO.MMOServer.Events {
    using Common.Codes;
    using Common.Types;
    using Photon.SocketServer.Rpc;

    class NewPlayerEvent {
        [DataMember(Code = (byte)ParameterCode.Username)]
        public string Username;

        [DataMember(Code = (byte)ParameterCode.Position)]
        public Vector Position;
    }
}

you should not use SendMessage method. use SendEvent instead

best,
