CB Multipart
by covers1624
CB Multipart is a Forge and NeoForge library that lets several functional blocks occupy one block space.
What it does
The library provides a multipart API that other mods use to place more than one functional block in a single block space, along with micro blocks and support for vanilla multipart and microblock content. CodeChicken Lib is required and must be installed alongside it. Nine other mods, including Project Red Core and Translocators, require CB Multipart. Files exist for 1.5.2 – 1.21.1 across 13 release versions, and the code is open source under the GNU Lesser General Public License v2.1 only.
Key features
Multipart API
A developer API lets mods combine several functional blocks inside one block space.
Micro blocks
Micro blocks fill part of a block space, so smaller pieces can share a position with other content.
Vanilla multipart support
Multipart and microblock content from older versions is supported by the library.

How it compares
HammerMultipart is a Forge and NeoForge option for 1.20.1 – 1.21.1 under All rights reserved, so it is not open source. CustomHitboxLib is open source under the MIT License for the same loaders and versions, but it adds hitboxes rather than block space sharing.
