SynapseLib

by Modrome

SynapseLib is a Forge library for 1.12.2 that gives other mods a set of shared helper functions for common development tasks.

ForgeClient and serverCustom license1.12.2

What it does

Developers who build mods on top of SynapseLib get helpers for random number generation, detecting blocks in the area around a position, checking the material type of a block, reading and writing configuration files, clamping values to a range, generating block blacklists, breaking blocks with entity-based functions, and formatting chat messages. The library itself adds no blocks, items or mechanics for players to use directly.

Wyrms of Nyrus requires SynapseLib, so installing that mod on a Forge 1.12.2 instance means adding this library too. SynapseLib is published only for Forge and only for 1.12.2, with the latest file being 4.0, dated 2024-10-26. Installation covers the server and each player's game. The code is covered by a custom license and is not open source.

Key features

  1. Random number helpers

    Utility functions for generating random values, meant to be called from other mods' code.

  2. Proximity block detection

    Functions that search the blocks near a position, so a mod can react to nearby blocks.

  3. Material type checks

    Helpers that test which material category a block belongs to, without hand-written lookups.

  4. Config and chat utilities

    Helpers for reading and writing configuration files and for formatting chat text.

How it compares

Full comparison

Ez Mod Lib is an MIT-licensed open source library that works on both Forge and NeoForge for 1.16.5 – 1.20.1, and either side can run it, and neither needs it. Dio's Lib is open source under the GNU Lesser General Public License v3.0 or later, for Fabric, Forge and NeoForge across 1.19.3 – 26.2, and it has to be on both the server and every player's client. SynapseLib is limited to Forge and to 1.12.2, and its custom license keeps it closed.
