Thor Patcher and Auto-Updater

[OverLord]

Well ... I saw the Thor Patcher does not receive more updates and Windows 8.1 it is considered virus and unless it is started as "Administrator" he can not open the executable of the game when you click "Start". So, I was wondering if anyone would have the Thor source code to provide for the community update or someone could pass me some study material on how to unpack one GRF, add or remove files on it and compacting again. For I am thinking of creating a new auto-updater in C # if we can not solutions for Thor.

Heya,

If you're going to do a patcher via C#, then you can download GRF Editor's sources over here : http://www.mediafire.com/download/7z6hkdag4ayj8rs

Add a reference to the dlls found in the "Output Libraries" folder to your project and you can use the following code to get you started :

using System;using System.Diagnostics;using System.IO;using System.Windows.Forms;using GRF.Core;using GRF.FileFormats.RgzFormat;using GRF.FileFormats.ThorFormat;using GRF.IO;using Utilities.Extension;namespace TestPatcher { public partial class Form1 : Form { public Form1() { InitializeComponent(); Patch(); } public void Patch() { var patchesPath = @"Catches"; var patcherExeName = Path.GetFileName(Process.GetCurrentProcess().MainModule.FileName); var roDirectory = Directory.GetCurrentDirectory(); var serverGrfName = @"server.grf"; var temporaryGrfName = @"temp.grf"; using (var output = new GrfHolder(temporaryGrfName, GrfLoadOptions.New)) { foreach (var patchFile in Directory.GetFiles(patchesPath)) { if (patchFile.IsExtension(".grf", ".gpf")) { using (var grf = new GrfHolder(patchFile)) { output.QuickMerge(grf); } } else if (patchFile.IsExtension(".rgz")) { using (var rgz = new Rgz(patchFile)) { if (rgz.Table.ContainsFile(patcherExeName)) { // Updating on this executable, do something...! throw new NotImplementedException(); } foreach (var entry in rgz.Table) { entry.ExtractFromRelative(roDirectory); } } } else if (patchFile.IsExtension(".thor")) { using (var thor = new Thor(patchFile)) { if (thor.Header.UseGrfMerging) { string targetGrf = thor.Header.UseDefaultTargetGrf ? serverGrfName : thor.Header.TargetGrf; if (string.IsNullOrEmpty(targetGrf)) throw new Exception("THOR extraction failed : no target GRF identified."); if (String.Compare(serverGrfName, targetGrf, StringComparison.OrdinalIgnoreCase) == 0) { output.QuickMerge(thor.ToGrfHolderQuick()); } else { using (var grf = new GrfHolder(targetGrf, GrfLoadOptions.OpenOrNew)) { grf.QuickMerge(thor.ToGrfHolderQuick()); } } } else { if (thor.Table.ContainsFile(patcherExeName)) { // Updating on this executable, do something...! throw new NotImplementedException(); } foreach (var entry in thor.Table) { entry.ExtractFromRelative(roDirectory); } } } } } using (var serverGrf = new GrfHolder(serverGrfName, GrfLoadOptions.OpenOrNew)) { serverGrf.QuickMerge(output); } } GrfPath.Delete(temporaryGrfName); } }}

Obviously this is not optimized and errors are not handled at all, but it yields good results nonetheless. I would definitely not recommend you to start from scratch to make a patcher.
