OpenModsLib Unofficial

OpenModsLib Unofficial The foundation behind OpenBlocks Unofficial, updated for Minecraft 1.21.1 and NeoForge.

This focused port provides the shared inventory, experience, networking, geometry and calculation systems used by OpenBlocks. It is a support library, not a standalone gameplay mod. Install it when using the matching OpenBlocks Unofficial release.

Installation Requires Minecraft 1.21.1, NeoForge 21.1.252 and Java 21. Place the OpenModsLib JAR in your mods folder. When using OpenBlocks, install the exact matching release version of both mods on the client and server. No OpenPeripheral mod or computer mod is required. Compatibility This is a modernized library, not a way to run old Forge mods on NeoForge. Obsolete systems have been replaced with current APIs, and unused legacy frameworks have been removed. It is not compatible with the original library’s programming interface.

Do not install this alongside another OpenModsLib version or port using the openmods mod ID. The current version is the 1.0.0 unofficial release.
