Key To Heaven - New Launch - William - 24-06-2019

I have begun working on K2H again and plan on launching a new server shortly. The new K2H will offer a sizeable client so that you can play in any resolution and new updated UI menus to make it look more modern.
Hope to see you around Smile

Re: Key To Heaven - New Launch - William - 26-06-2019

I began porting my server to vb.net a few days ago and its going pretty well. There is still a lot of work to be done though. So I will probably share some more information when I get closer to completion.

Re: Key To Heaven - New Launch - Pbcrazy - 26-06-2019

That will be neat to read about! Looking forward to it!

Re: Key To Heaven - New Launch - William - 27-06-2019

How to Port to .net or .net Core.
1. Download Visual Studio 2008.
2. Open your VB project with it and chose convert and run the wizard (begin with the server, its easiest).
3. Run your new vb.net server, and fix all the common errors that appeared.
4. Remove your frmServer and create a new form called ServerWindow (move some data if needed from frmServer).
5. Download https://www.codeproject.com/Articles/11422/Winsock-NET
6. Implement winsock net to your project.
7. If you have byte arrays you will have more difficulties, I had to rewrite all of modBuffer etc.
8. Make sure things work, connect the client.

I'm almost done now I think, but this just covers the porting, not the improving. If anybody wanna try Im more than happy to assist with questions. I will probably make a more detailed post later, but hey I dont think anybody else is actually gonna try it so i'll wait Smile

Re: Key To Heaven - New Launch - Pbcrazy - 27-06-2019

You make it sound so simple, but I'm sure there were many hours put into hunting down errors! lol

Re: Key To Heaven - New Launch - William - 27-06-2019

It all depends on the knowledge/how much time you have. But its very doable, and the less features you have the easier it is. Easiest would be for a normal MS version of course. I think I have spent maybe 15-20hours so far on the server.

And I can share code, for example all the code from the .net winsock so that would save time if someone else wants to try.

Re: Key To Heaven - New Launch - Pbcrazy - 27-06-2019

Ya, I think the winsock conversion would be the most troublesome for me.

I think my last project I was working on was using byte arrays, so that'll be fun. What was causing the greater difficulty with the conversion of those?

Re: Key To Heaven - New Launch - William - 27-06-2019

Hmm, the most troubling for me so far has been:
* I was not aware that VB6 and VB.net had missmatching variable declarations. So for example a Long in VB6 is a Integer in VB.net, a Integer in VB6 is a Short in VB.net. So that caused issues for me when I was trying to read all my binary data files (map,items etc...). Because all those bytes need to match exactly. And for some files they still didnt match and that was because VB6 just reads it and doesnt care if it missmatches with the length of the file. While vb.net crashes, but that was basicly solved by try catching the get function for the data, cause the data was still read.
* Encodings was a issue, there is like ASCII, ETF8, UNIFORM etc when converting to and from bytes. It took me sometime to grasp the fact that that was the issue. But I basically use System.Text.Encoding.Default. for now. You mainly just search for System.Text.Encoding. in your vb.net converted server to see all the locations for it.
* Its also a little tricky with the indexes of arrays, since vb6 has arrays from value 1-10 for exmple, but thats forbidden in vb.net (it has to start from 0). So there was a -1 here and there to take care of that.

Here is the winsock part, pretty short and simple. All you do is add:

Public Shared Network As New Sockethandler
in the ServerWindow class. And add:
in the ServerWindow form loaded sub.

And then you will have some errors with frmServer.Socket that you change to ServerWindow.Server...

Imports System.Collections.Generic
Imports System.Net.Sockets
Imports Winsock_Control

Public Class Sockethandler

    Public WithEvents Server As Winsock
    Public Sockets As New Dictionary(Of Integer, Winsock)
    Private m_SocketsToRemove As New List(Of Winsock)

    Public Sub Initialize()
        Server = New Winsock
        Server.LocalPort = 4000
        Server.RemotePort = 4000
        Server.RemoteIP = ""
    End Sub

    Public Function GetState(index As Integer) As WinsockStates
        If TryGetUser(index) Is Nothing Then
            Return WinsockStates.Closed
        End If

        Return TryGetUser(index).GetState
    End Function

    Public Function TryGetIndex(socket As Winsock) As Integer
        For Each item As KeyValuePair(Of Integer, Winsock) In Sockets
            If item.Value Is socket Then
                Return item.Key
            End If
        Return -1
    End Function

    Public Function TryGetUser(index As Integer) As Winsock
        If Sockets.ContainsKey(index) Then Return Sockets(index)

        Return Nothing
    End Function

    Private Sub Socket_ConnectionRequest(sender As Winsock, requestID As Socket) Handles Server.ConnectionRequest
            Dim i As Integer
            i = FindOpenPlayerSlot()

            Sockets.Add(i, sender)
            Dim ws As Winsock = CType(sender, Winsock)

            AddHandler ws.DataArrival, AddressOf wsk_DataArrival
            AddHandler ws.Disconnected, AddressOf wsk_Disconnected


            Call AcceptConnection(ws, requestID, i)
        Catch ex As Exception
        End Try
    End Sub

    Private Sub wsk_Disconnected(sender As Winsock)
        If m_SocketsToRemove.Contains(sender) Then Exit Sub

        If m_SocketsToRemove.Count > 0 Then
            Catch ex As Exception
            End Try
        End If
    End Sub

    Private Sub wsk_DataArrival(sender As Winsock, BytesTotal As Integer)
        If IsConnected(TryGetIndex(sender)) Then
            Call IncomingData(TryGetIndex(sender), BytesTotal)
        End If
    End Sub

End Class

I'm finally able to login to the game with the .net server Big Grin Big Grin Big Grin This is big progress, now I just need to take care of the remaining issues, but being able to login is huge in continuing the work.

Re: Key To Heaven - New Launch - Pbcrazy - 29-06-2019

That's awesome! You're making really quick progress there.

Re: Key To Heaven - New Launch - William - 29-06-2019

I lost many hours trying to investigate a socket/packet issue though. And it turns out there where things needed to be changed in the .net winsock for it to work on mirage. But now Ive made adjustments to it and things are looking better again. So if anybody attempts this they should probably ask me to post the code changes for the .net winsock.

Re: Key To Heaven - New Launch - William - 29-06-2019

From what I can see now the server port is finished. There are no more issues that im aware of right now Smile This doesnt mean that all the server work is done though, it just means that its playable but there is not much gained from the port at the moment. So next step for the server will be to rewrite the socket system to a modern tcp system etc. But before all that I will port the client also so I have everything in .net working before I start doing optimizations. Thats the plan Smile Click url to see full screenshot.

Re: Key To Heaven - New Launch - William - 16-07-2019

The progression is going really well, we now have SFML in the VB.NET client. You can follow the work here:

Re: Key To Heaven - New Launch - Pbcrazy - 18-07-2019

Forgive my ignorance but what is SFML?

Re: Key To Heaven - New Launch - William - 18-07-2019

I'm using SFML for the graphics and most likely the audio ( https://www.sfml-dev.org/ )

Quote:SFML provides a simple interface to the various components of your PC, to ease the development of games and multimedia applications. It is composed of five modules: system, window, graphics, audio and network.
With SFML, your application can compile and run out of the box on the most common operating systems: Windows, Linux, macOS and soon Android & iOS.

It is basically .dll files that you include in your project that allows you to render graphics.

Re: Key To Heaven - New Launch - Pbcrazy - 19-07-2019

oh neat! Trying to go cross platform or just found it easy to use?

Re: Key To Heaven - New Launch - William - 19-07-2019

It's mainly easy to use and works well for this project, I dont have any plans to go cross platform for the client.

Re: Key To Heaven - New Launch - William - 14-09-2019

Posting this here for further info on how to port to .net, I had these notes on my computer so before they get lost I share them:

Quote:1. Download and install: http://go.microsoft.com/fwlink/?linkid=321343
1.1 Make sure it works on computer without powerpacks installed. Those files should be included in EXE.
2. Needed to put Interop.DxVBLib.dll into my: C:\Windows\SysWOW64 folder!
3. Temporarily added ms symbols (should be able to ignore this): http://www.vbforums.com/showthread.php? ... e-PDB-file
4. Net framework 4 on project.
5. Used this for smooth form transitions: http://vbcity.com/forums/t/158363.aspx (put in my basepage).
