MinecraftLauncherParameters

You can change the default behavior of the launcher.

Example

var path = new MinecraftPath();
var parameters = MinecraftLauncherParameters.CreateDefault(path);

// set default RulesEvaluator
parameters.RulesEvaluator = new RulesEvaluator();

// load only the locally installed version 
parameters.VersionLoader = new LocalJsonVersionLoader(path);

// set default JavaPathResolver
parameters.JavaPathResolver = new MinecraftJavaPathResolver(path);

// use single-threaded game installer
parameters.GameInstaller = new BasicGameInstaller(parameters.HttpClient);

// modify default file extractors
var extractors = DefaultFileExtractors.CreateDefault(
    parameters.HttpClient, 
    parameters.RulesEvaluator!, 
    parameters.JavaPathResolver!);
extractors.Asset!.AssetServer = MojangServer.ResourceDownload; // set asset download server
extractors.Library!.LibraryServer = MojangServer.Library; // set library download server
extractors.Java = null; // remove JavaFileExtractor
extractors.ExtraExtractors = []; // add additional file extractor
parameters.FileExtractors = extractors.ToExtractorCollection();

// initialize a new launcher with parameters
var launcher = new MinecraftLauncher(parameters);

MinecraftPath

See Minecraft Path

var path = new MinecraftPath();
var parameters = MinecraftLauncherParameters.CreateDefault(path);

HttpClient

All HTTP requests use this HttpClient. You can use Polly for features like automatic retries on failed requests and failed downloads.

var path = new MinecraftPath();
var httpClient = new HttpClient();
var parameters = MinecraftLauncherParameters.CreateDefault(path, httpClient);

RulesEvaluator

See Rules

parameters.RulesEvaluator = new RulesEvaluator();

VersionLoader

See Versions

parameters.VersionLoader = new MojangJsonVersionLoaderV2(path, httpClient);

JavaPathResolver

See Java

parameters.JavaPathResolver = new MinecraftJavaPathResolver(path);

GameInstaller

See GameInstaller

parameters.GameInstaller = ParallelGameInstaller.CreateAsCoreCount(httpClient);

FileExtractors

See FileExtractor

var extractors = DefaultFileExtractors.CreateDefault(
    httpClient, 
    parameters.RulesEvaluator, 
    parameters.JavaPathResolver);
parameters.FileExtractors = extractors.ToExtractorCollection();
