FileChecker

Check file existence and SHA1 hash to check if file is valid or invalid, and return invalid file list. Downloader will download these files.

All file checker should inherit IFileChecker. There are 5 default file checkers, AssetChecker, ClientChecker, LibraryChecker, LogChecker, and JavaChecker.

Example

var launcher = new CMLauncher(new MinecraftPath());

// Skip asset file checking
launcher.GameFileCheckers.AssetFileChecker = null;

// Skip hash checking of library files
launcher.GameFileCheckers.LibraryFileChecker.CheckHash = false;

// Use BMCLAPI mirror server
launcher.GameFileCheckers.LibraryFileChecker.LibraryServer = "https://bmclapi2.bangbang93.com/maven";
launcher.GameFileCheckers.AssetFileChecker.AssetServer = "https://bmclapi2.bangbang93.com/assets";

// Add custom file checker
launcher.GameFileCheckers.Add(new MyFileChecker());
