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.

Key features

  1. Ray cast functions

    Adds ray casting functions beyond the standard command set, for scripts that need to trace a line and read the result.

  2. Data pack commands

    Works through data pack commands, so it can be used on servers that do not run a mod loader for the client side.

  3. Shape summoning

    Supports summoning entities or shapes along a cast, with the size of the shape depending on the cast settings.
