s2protocol.NET 0.9.0

Introduction

dotnet wrapper for Blizzards s2protocol for decoding/parsing StarCraft II replays (*.SC2Replay)

Getting started

Installation

dotnet add package s2protocol.NET

Usage

ReplayDecoder decoder = new();
Sc2Replay? replay = await decoder.DecodeAsync(pathToSC2Replay);
Console.WriteLine(replay.Header.BaseBuild);

Optional options:

ReplayDecoder decoder = new();

ReplayDecoderOptions options = new ReplayDecoderOptions()
{
    Details = false,
    Metadata = false,
    MessageEvents = false,
    TrackerEvents = true,
    GameEvents = false,
    AttributeEvents = false
};

CancellationTokenSource cts = new();

Sc2Replay? replay = await decoder.DecodeAsync(pathToSC2Replay, options, cts.Token);
Console.WriteLine(replay.TrackerEvents.SUnitBornEvents.FirstOrDefault());

Multiple replays:

ReplayDecoder decoder = new();
var folder = "path_to_replay_folder";
List<string> replays = Directory.GetFiles(folder, "*.SC2Replay").ToList();
ReplayDecoderOptions options = new ReplayDecoderOptions() { TrackerEvents = false };
int threads = 8;
CancellationTokenSource cts = new();

int decoded = 0;
int errors = 0;
await foreach (DecodeParallelResult decodeResult in decoder.DecodeParallelWithErrorReport(replays, 2, options, cts.Token))
{
    if (decodeResult.Sc2Replay == null)
    {
        Console.WriteLine($"failed decoding replay {decodeResult.ReplayPath}: {decodeResult.Exception}");
        errors++;
    }
    else
    {
        Console.WriteLine($"{decoded} {decodeResult.Sc2Replay.Details?.DateTimeUTC}");
        decoded++;
    }
}

Known Limitations / ToDo

GameEvents

STriggerSoundLengthSyncEvent ⇒ no data SControlGroupUpdateEvent ⇒ no mask No BigInteger support
