[GUIDE]KOP-Launcher

Recommended Posts

Hi,

 

I made a kind of guide to configure Patrick13's launcher, I don't know if there are new people but I'm going to post it :p

 

IMPORTANT

I don't know how this works so this is just one way to make it work but it is not the best way.

 

 

API: Download

Launcher:


1-Configure API

Spoiler

 

I- Download API, go to the web folder of your server, create a folder called API and paste the files, like this:

II- Edit config.php with your info

<?php
$db = [
    'host' => 'HOSTDB',
    'username' => 'USERDB',
    'password' => 'PASSDB',
    'accountserver' => 'AccountServer',
    'gamedb' => 'GameDB',
    'portGate' => '1971'
];
?>

III- Edit update.xml

<ListUpdate>
        <Update>
            <FileURL></FileURL>
            <FileMirror></FileMirror>
      <Version>1.0.0.0</Version>
        </Update>
</ListUpdate>

The first version of the client is 1.0.0.0 then to start downloading you must start from 1.0.0.1 onwards, just add a download like this:

Spoiler


<ListUpdate>
         <Update>
            <FileURL></FileURL>
            <FileMirror></FileMirror>
            <Version>1.0.0.0</Version>
        </Update>

        <Update>
            <FileURL>http://urltomyfile.com/downloads/patch1001.zip</FileURL>
            <FileMirror>http://mirror.urltomyfile.com/downloads/patch1001.zip</FileMirror>
            <Version>1.0.0.1</Version>
        </Update>
</ListUpdate>

 


 

 

2.-Create TABLE for version

Spoiler

 

I.- Open SQL Server Management and connect to your databases

Go to Databases>GameDB>Right click>New Query copy and paste

CREATE TABLE Launcher (idPatch INT NOT NULL PRIMARY KEY IDENTITY, versionPatch VARCHAR(10) NOT NULL)

Press F5, refresh Databases o re-connect to load your new table.

Go to Databases>GameDB>Tables>Launcher>Right click>Edit  and add a new patch.

Press Enter and F5

Now you can go to your URL and test, example: http://mySuperSVR.com/api/statistics.php

Should load something like this:

3.-Configure PKO-Launcher

Spoiler

 

I.- Download PKO-Launcher, open Visual Studio (i use 2019 community)

Open Properties>Resource.resx

 

spacer.png

 

You must add StatusUrl

II.-Find GetIPByServer in Globals.cs

Change NAMEISLAND and IPHERE

public static string GetIpByServer ( string server )
        {
            string ip;

            var morganRegions = new List<string> { "" };
            
            switch ( server )
            {
                case string external when external.ToLowerInvariant (  ).Contains ( "NAMEISLAND" ):
                    ip = Task.Run(async () => await GetBestServer(morganRegions, "")).Result;
                    break;
                default:
                    ip = "IPHERE";
                    break;
            }

            return ip;
        }

III.-Find PopulateRegion in Utils.cs

Put the same region

public static bool PopulateRegion ( Guna2ComboBox control )
        {
            try
            {
                if ( control == null ) return false;

                control.Items.Add ( "NAMEISLAND" );
                control.SelectedItem = "Select Region";

                return true;
            }
            catch
            {
                return false;
            }
        }

IV.-Find UpdateServerStatistics in kopMainF.cs
Replace with this:

Spoiler


private async Task UpdateServerStatistics()
        {
            bool online = false;
            try
            {
                await Task.Run ( () =>
                {
                    ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
                    ServicePointManager.DefaultConnectionLimit = 20;

                    using (var wc = new WebClient ( ))
                    {
                        wc.Proxy = null;

                        var json = wc.DownloadString(Resources.StatisticsURL.ToString()); ;
                        var jsonS = wc.DownloadString (Resources.StatusUrl.ToString());
                        JArray data = JArray.Parse (json);
                        online = bool.Parse(jsonS);                 

                        foreach (JObject item in data)
                        {
                            SetControlThreadSafe(label7, arg => { label7.Text = item.GetValue("accounts").ToString(); }, null);         //total account
                            SetControlThreadSafe(label9, arg => { label9.Text = item.GetValue("characters").ToString(); }, null);       //total character
                            SetControlThreadSafe(label6, arg => { label6.Text = item.GetValue("online").ToString(); }, null);           //current online
                            SetControlThreadSafe(label15, arg => { label15.Text = item.GetValue("max_online").ToString(); }, null);     // <.< idk

                            _gameVersion = item.GetValue("version").ToString();
                        }

                        string hashes = "9BkAxPDlBSDhb13b73HFKFOl915sD";
                        var contents = hashes.Split ( new[] {Resources.StatHashSumDelimiter}, StringSplitOptions.None );

                        foreach (var hash in contents)
                            if ( !string.IsNullOrEmpty ( hash ) )
                                Globals.GenuineResourceHashes.Add ( hash );

                        if (online != false)
                            SetControlThreadSafe ( label11, arg => { label11.Text = "Online"; }, null );                                 //server status
                        else

                            SetControlThreadSafe ( label11, arg =>
                            {
                                label11.ForeColor = Color.DarkRed;
                                label11.Text = "Offline";
                            }, null );
                    }
                } );
            }
            catch
            {
                // ignored
            }
        }

 


 

Done!!

*Use ZIP for patchs

 

 

 NOTE:

Spoiler

In Statistics.php we have this query:

$sql = $dbConn->prepare('SELECT (SELECT COUNT(*) FROM character WHERE delflag=0)  as characters, (SELECT COUNT(*) FROM character WHERE mem_addr>0) AS online, (SELECT COUNT(*) FROM account) AS accounts, (SELECT COUNT(DISTINCT last_ip) FROM account) as users, (SELECT MAX(login_num) FROM stat_log) as max_online, (SELECT MAX(versionPatch) FROM Launcher) as version');

the only change is this in the end

(SELECT MAX(versionPatch) FROM Launcher) as version')

In ServerStatus.php we have this to check connection

$fp = @fsockopen('tcp://' . $db['host'], $db['portGate'], $errno, $errstr, 3);

PD: StatHashSumDelimeter must finish thisyou can add a new column in the table of Launcher with this parameter.

I can’t remember sorry, I’ve not worked on this project in a while, I can quickly read through the source code later to see what could be causing the issue.

You can't start the game because of this statement:

if ( !string.IsNullOrEmpty ( _gameVersion ) )

If game version is null or empty, then it will show the following message:

Utils.ShowMessageA ( "Retrieving update information, please try again in a few seconds." );

To fix that, you either need to override this condition or add an API through which the latest game version can be retrieved (as per the tutorial above I believe). That is as can be seen in the method below: 

UpdateServerStatistics()

Which connects to the API using the following URL:

var json = wc.DownloadString ( Resources.StatisticsURL );

And retrieves the game version here:

 _gameVersion = data.version;

 

Hope that was helpful and good luck!
