Exthylanes Extra Stuff
by Exthylane
Exthylanes Extra Stuff is a Fabric library for mod authors, with helper methods for blocks, items, entities, particles and screen coordinates.
What it does
Developers who write Fabric mods can call the library's methods instead of writing the same code again. It collects helpers for math tasks such as reading a block position from a player, or a player's yaw and pitch, along with methods that register blocks and items and a registry helper for entities.
The library also converts three-dimensional world coordinates into two-dimensional screen coordinates, which is useful for drawing interface elements over the game view. A particle-spawning method works on the client without sending packets to sync the effect with the server. Cardinal Components API and Satin API are bundled inside the mod, so no separate install is needed for them.
Exthylanes Extra Stuff is published for Fabric only, with files for 1.20.1 and a latest build of 1.6.3 dated 2026-05-10. Every player and the server need a copy of the mod. The mod is released under All rights reserved, which means it is not open source. Reliving The Moment requires it.
Key features
Block and item registration
Methods register blocks and items, reducing the setup code a mod needs for its own content.
Entity registry helpers
Helper methods simplify registering entities, so entity types are declared with fewer calls.
Client particle spawning
A method spawns particles on the client directly, without requiring packets to keep the effect in sync.
Coordinate conversion
Helpers convert 3D world coordinates into 2D screen coordinates for rendering interface elements.
