Shaper
by vowxky
Shaper is a library for modders that loads, exports and applies voxel shapes and hitboxes defined as JSON.
What it does
A modder can define a block's voxel shape or hitbox in a JSON file and have Shaper load it, or write the shapes directly from code. The Shaper Blockbench plugin exports shapes that can be used with the library. Further details are on the project wiki. Shaper runs on client and server, so both the server and every player need it. Files are published for Fabric, Forge, NeoForge and Quilt, covering 1.20.1 – 1.21.1 across three release versions, under All rights reserved, and the mod is not open source.
