Simple Absorption
by KnightMiner
Simple Absorption makes absorption hearts recover over time under the same rules vanilla hearts use, and it can disable natural regeneration.
What it does
Absorption hearts are a gold buffer on top of the health bar. With this mod they come back gradually, using the same recovery mechanics as ordinary hearts, so a world where natural regeneration is turned off gives players a second source of healing. The full health bar then regenerates only through absorption, which changes how fights and travel play out.
Four separate ways of gaining natural absorption hearts can be switched on or off through a small config file stored in each world folder. The mechanic is inspired by one used in the Super Hostile maps by Vechs and in the Natural Absorption mod by FatherToast. This version was rewritten from scratch, which makes it easier to maintain, while keeping the base functionality so it works in existing worlds. Simple Absorption is published for Forge only and runs on client and server, so the server and every player need it. Its files target 1.15.2 – 1.20.1, and the license is the MIT License, so the code is open source.
Other absorption-related mechanics exist in Natural Absorption, and the author notes that this mod does not cover them yet, so they are left for later consideration.
