About this Mod

Pisces Libs is an essential modding library for item related things and easier multi-loader porting.

You'll need to install this alongside Aquarius libs for it to function properly.

By itself it wont change the game much,

but it has functions and variables implemented that makes updating and porting mods much easier.

Also makes the mod creator use much less code when creating a new mod

as it simplifies item registrations and handling components and attributes easier.

The mod currently supports forge, fabric and neoforge 1.21.5 - 1.21.11, 26.1.x.

It wont support versions below 1.21.5.

Pisces Libs officially supports fabric, forge, neoforge for Minecraft 26.1.2, 26.1.1, 26.1. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Pisces Libs – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Pisces Libs consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
