ExoLib
by Exosomnia
ExoLib is a Forge library for 1.20.1 that other Exosomnia mods build on, providing shared helpers for loot, particles, player data and timed actions.
What it does
ExoLib does not add gameplay on its own. It is a library used by other mods from the same author, and the author notes that the mod is unstable in development and mostly useful as a dependency. Two catalog mods require it: ExoVeinmine and ExoArmory, so a server that runs either of them needs ExoLib installed as well.
The library gathers several kinds of utility code in one place. Loot table injections let other mods add entries to existing loot tables, particle helpers draw shapes made of particles, and a capability-based store keeps persistent data on players. Tags on players can be synced between server and client, and a ScheduleManager runs delayed or repeating actions. The author describes the library as covering a wide set of shared functions.
The mod is published for Forge only, for Minecraft 1.20.1, and runs on client and server, so both the server and every player need it. It is released under the GNU Lesser General Public License v3.0 only and is open source, with public source code. The first build was published on 2025-04-15 and the latest Forge file, 1.0.0, followed on 2025-07-10.
Key features
Loot table injections
Other mods can add entries to existing loot tables without replacing them, using a simple injection call.
Particle shape helpers
Helpers spawn particles arranged into shapes, for effects that other mods can reuse.
Persistent player data
A capability-based store lets mods keep custom data on players that survives logging out and back in.
Synced player tags
Tags set on a player are kept in step between the server and the client.
Scheduled actions
A ScheduleManager runs delayed or repeating actions, so mods do not need their own timing code.

What the author says
This mod by itself doesn't add any functionality to the game, it's an unstable, development library mod required for my other mods. All of the features in this library can only be accessed via development as a dependency except for Loot table & Loot pool injections. You can add your own custom injections via a…
