Archive of an old 1.12 mod of ours. Glass Hearts will not receive further updates.
A novel and balanced way to increase your health.
Glass Hearts adds five things:
- An enchantment, called Sapping
- A fluid, called Lifeforce
- A block, called a Glass Heart
- A few gems, to supplement the ones in vanilla
- A completely overhauled health bar renderer, with sub-half-heart accuracy
Sapping allows you to fill bottles with Lifeforce by killing mobs. By default, you cannot gain Lifeforce from undead mobs, and there's a config option to only allow getting it from players.
Glass Hearts allow you to increase your max health, but don't refill on their own. You can adorn these hearts with 1 gem to give special effects, dependent on the gem.
Automated piping can refill Glass Hearts, but only so fast. In addition, multiple players can share a Glass Heart.
But beware; Glass Hearts are targetted by creepers (configurable), and can be difficult to refill! In a PvP setting, enemy players might break it instead!
Glass Hearts do not chunkload and instead store their data out-of-band in a global map. This means you can utilize a Glass Heart in an unloaded chunk without worrying about it, unless you have an automated refill system.
Not even Regeneration will work on a Glass Heart, nor healing offered by other mods.
This mod idea was originally intended for a factions PvP server, but I'm releasing it as an open-source Forge mod because I can't just continue to not implement this idea. I hope you enjoy!
All information about the mod is provided as a series of screenshots and descriptions on the Gallery tab — a transcription of the original Imgur album.
