InterdimensionalLib
InterdimensionalLib is a utility library for Fabric and Quilt that gathers commonly needed functions for other mods, shipped for 1.21.1.
What it does
Developers and modpack builders get a shared set of helpers in one place: block set type registration, custom note block instruments, a custom biome registry, and a set of utility classes such as MathUtils, ItemUtils and AdvancementHandler. Other mods can call these functions instead of carrying their own copies, and the mod also covers buttons and pressure plates that can be opened by a wind charge or by hand.
The mod is a Library and it needs Cloth Config API and Fabric API installed beside it. Installation covers the server and each player's game. The license is the MIT License and the source code and issue tracker are public. Builds exist for Fabric and Quilt, with 1.1.2 for 1.21.1 as the latest file, published on 2026-05-10.
Key features
Block set type registration
Adds a way to register a custom BlockSetType, so new doors, buttons and plates can follow their own rules.
Custom note block instruments
Lets another mod register its own instruments for the note block.
Custom biome registry
Registers biomes from code through a mixin, so mods can add their own biome sets without datapacks.
Grindstone recipes
Supports custom recipes that run when a player right-clicks a grindstone.
Screen and sky effects
Utility datapacks cover camera screenshake, closing screens, hiding the GUI and changing sky fog.

Use cases
Mod developers
A developer who needs a block set type, a note block instrument or a custom biome can reuse this code instead of writing it again.
Modpack builders
A pack that combines several small mods can ship one shared library rather than many overlapping helpers.
Who it’s for: Mod developers building on Fabric or Quilt, and modpack builders who want shared helper code available to other mods.
How it compares
Farest's API is a Fabric-only library for 1.21 – 1.21.10, licensed under the GNU Lesser General Public License v3.0 only and open source. Bento Util is also Fabric-only, and is open source under the same license, but it is client or server optional, which means either side can run it without it being required. InterdimensionalLib covers Fabric and Quilt under the MIT License, with client and server needing it on both sides.
