Description

Level Up HP is a mod that adds RPG style HP upgrades. As you kill mobs, you gain HP XP, which eventually gives you HP Levels, which give you additional hearts of health. The mod is designed with mod packs and servers in mind; so it's fully configurable. You can configure the starting and maximum HP, the HP XP requirements to level up, the penalties on death, whether to reset HP Levels on death, and more! There are also commands that allow ops or command blocks to manage HP XP and HP Level for any player.

Installation

This mod requires Forge and ~~Kottle~~.
~~If you want to start at 10 hearts instead of 5, get the Level Up HP Easy Start data pack~~
~~Optionally, add Data Loader to apply the config at a global level instead of per-save~~

Features

Increase your max HP by killing mobs
Configure just about everything using ~~data packs~~, like starting HP, max level, progression formula, and penalty formulas. You can even set XP values for individual mobs, including modded ones! See the section on data packs in the wiki. There's also a preconfigured example data pack that starts you off with a full 10 hearts of health instead of 5.
HP XP overlay HUD
Heart containers that instantly give you an HP level. You can use a data pack to add these to dungeon loot, include them in adventure maps, whatever you want. By default, they're not obtainable in survival.
~~Level up trigger for use in data packs; see one of the built in advancements for a usage example. Supports int range conditions (just like many vanilla triggers) on current and remaining levels.~~
~~Command (/leveluphp check) to check XP/Level in case you have a mod that conflicts with the xp bar hud~~
~~Op-only commands to manage XP/Level for any player~~
- ~~/leveluphp [setxp|addxp|setlevel|addlevel]~~
- ~~You can use these with command blocks or mcfunctions too~~
