Silver's Ray Cast Library | RCL
by ItzSilver_
Silver's Ray Cast Library (RCL) is a library that gives other mods and data packs a ray casting toolkit, with extra functions beyond the standard ones.
What it does
Ray casting lets a script trace a line from a point and read what it hits. RCL extends that idea with more functions than the usual set, and it was made because command-only limits made some casts awkward to write. The library also ships as a data pack, so server owners can use its commands without installing a mod on the client.
Environment: only the server needs RCL for its functions to run, and players can join without installing it. Files are published for Fabric, Forge, NeoForge and Quilt, with the current build 1.1 for 26.3 covering 1.21 – 26.3 (17 release versions). The mod is under All rights reserved, so it is not open source, and Silver's Project Info is an optional dependency.
