Console Client

[Matroblend]

Ok I am stuck I when I run he console client in debug mode I get the following errors.
I have checked my code against the videos from the start of the console project many times now.

This is in Visual Studio Debug
Additional information: Unable to cast object of type 'System.String' to type 'System.Byte[]'.

This is in the console not Debug
Unhandled Exception: System.InvalidCastException: Unable to cast object of type 'System.String' to type 'System.Byte[]'.

Thanks, exactly what I needed.

I see the code eventually refers back to a photon engine call.
What version of Photon are you using?
The code snippet you provided matches mine perfectly, but I am using photon-3-4-30 still.

I am also using 3-4-30

Only a couple of thoughts here.

EventReaderModuleRegistration.cs

using System;
using System.Collections.Generic;
using BuzzMMO.Base;

namespace BuzzMMO.Client.Infrastructure
{
    public class EventReaderModuleRegistration
    {
        public EventCode Code { get; private set; }
        public Action<EventCode, Dictionary<byte, object>> Action { get; private set; }

        public EventReaderModuleRegistration(EventCode code, Action<EventCode, Dictionary<byte, object>> action)
        {
            Code = code;
            Action = action;
        }
    }
}

EventCode.cs

namespace BuzzMMO.Base
{
    public enum EventCode : byte
    {
        SyncSystemsComponentMap,
        AddSystem,
        RemoveSystem,
        InvokeMethodOnSystem
    }
}

at the top of SystemsEventReader.cs

       public IEnumerable<EventReaderModuleRegistration> GetRegistration()
        {
            return new[]
            {
                new EventReaderModuleRegistration(EventCode.InvokeMethodOnSystem, InvokeMethodOnSystemEvent),
                new EventReaderModuleRegistration(EventCode.AddSystem, AddSystemEvent),
                new EventReaderModuleRegistration(EventCode.RemoveSystem, RemoveSystemEvent),
                new EventReaderModuleRegistration(EventCode.SyncSystemsComponentMap, SyncSystemsComponentMap)
            };
        }

The rest of the calls appear to be inside photon. That's why I mentioned it earlier.
You know it's got to be a typo somewhere

Mine looks like yours except it looks like you have EventCode outside of the Infrastructure namespace.

Maybe Nelson moved the files around later. My EventCode.cs is in the root of the Base project.
What my quoting failed to do was where I'd like to highlight in red wherever it said byte. Trying to stuff a string into a byte parameter is what you need to be checking at every point.

Another area I'd be looking at would be following through in SystemsEventReader.cs and seeing what sort of array was created in GetRegistration as quoted above. Set a breakpoint in program.cs
maybe even near the start. It would be interesting to see where the string is stuffed into the array where the SyncSystemsComponentMap method expects a byte.

OldnGrey, thank you for your help. I am not very good at debugging code and just learning the process.

My day job has put us into mandatory overtime, so I will not be able to work hard on this until 9/7.
But I really do thank you very much for your advice.
