LevelUP
by ReviloDev
LevelUP is a NeoForge library that adds a separate, global leveling and XP system on top of vanilla experience, for other mods to read and react to.
What it does
Players gain LevelUP experience through a custom level system that is kept apart from vanilla XP, so the two counters do not interfere. The progression curve that sets how much experience each level needs can be configured, which lets a pack tune how quickly players advance. The current level is shown at a glance, and a clean level display can be integrated into the inventory interface.
The library is built to be used by several mods at the same time. Other mods can read a player's level and XP, spawn LevelUP XP orbs, and react to level-up events. In the Mythcraft ecosystem it serves as the shared base for scaling difficulty and gating features as players progress.
LevelUP runs on client and server, so the server and every player need it. It is published for NeoForge only, for 1.21.1, and is released under All rights reserved, so the code is not open source, although public source code links exist.
