Quilt Loader
The Quilt Loader is the foundation of the Quilt ecosystem. It loads Quilt mods and provides the runtime environment, which can be extended through the Quilt Standard Libraries (QSL).
What the Quilt Loader does
Section titled “What the Quilt Loader does”Mod Initialization
It integrates with Minecraft’s startup process to discover, load, and initialize Quilt mods in the correct order.
Dependency Management
It verifies that all required dependencies (such as QSL) are installed, resolves version requirements, and prevents incompatible mod combinations from loading.
Class Transformation
It uses Mixins to safely modify Minecraft’s bytecode at runtime without directly changing the game’s files.
Fabric Compatibility
Quilt Loader maintains compatibility with most Fabric mods, allowing many existing Fabric projects to run on Quilt without modification.
