I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Overview

LovelyLib is the robot-specific library layer for the Lovely Robot mod family. It sits between HZLib and the three Lovely Robot variants — handling everything that is common to robot companions specifically, so that Legacy, Tribute, and Reboot all share the same foundation without duplicating it.

If you're installing any Lovely Robot mod, you need this.

What It Provides

Robot type system — LovelyRobotType with composable features (levelling, combat, protection, animation)
Animation Profile System — shared animation profile for all robot types (idle, walk, rest, sit, attack), built on HZLib's profile infrastructure
Feature composition — LevelFeature, CombatLevelFeature, ProtectionFeature wired together per robot type
Robot profile migration — version-aware NBT data migration so saves stay compatible across updates

Who Needs This

This is a library — it does nothing on its own. Install it alongside any Lovely Robot variant.

Required by:

Lovely Robot: Legacy
Lovely Robot: Tribute
Lovely Robot: Reboot

Also requires:

HZLib
