Usage

Install the nuget package e.g.

dotnet add package ii.Ascend

To edit a file you should instantiate the relevant class and call the Read method passing the filename. This will return an object model, which you can amend, before calling the Write method.

var hogProcessor = new HogProcessor();
var files = hogProcessor.Read(@"D:\Games\Descent2\DESCENT2.HOG");

foreach (var (filename, bytes) in files)
{
    var outputPath = Path.Combine(@"D:\data\descent", filename);
    Directory.CreateDirectory(Path.GetDirectoryName(outputPath)!);
    await File.WriteAllBytesAsync(outputPath, bytes);
    Console.WriteLine($"Extracted {filename} ({bytes.Length} bytes)");
}

var txbProcessor = new TxbProcessor();
var text = txbProcessor.Read(@"D:\data\descent\credits.txb");

// Reading a Descent 1 demo: extract game data from the PIG file first
var pigProcessor = new Descent1PigProcessor();
var (_, _, _, gameData) = pigProcessor.ReadDetailed(@"D:\Games\Descent\DESCENT.PIG");

var robotModelNums = gameData.Robots.Select(r => r.ModelNum).ToArray();
var robotIsBoss = gameData.Robots.Select(r => r.BossFlag != 0).ToArray();
var polyModelNumSubmodels = gameData.PolygonModels.Select(p => p.NumModels).ToArray();

var demProcessor = new DemProcessor();
var demo = demProcessor.Read(@"D:\data\descent\demo1.dem", robotModelNums, robotIsBoss, polyModelNumSubmodels);
Console.WriteLine($"Demo version: {demo.Version}, Game type: {demo.GameType}");
Console.WriteLine($"Total events: {demo.Events.Count}");
