HeartDev
I don't know my version or loader

--- Please, do not dowload versions named as "devOnly" or something similar, with 4 numbers on their version (like x.y.z.t) or marked as "alpha" version. These may contain bugs or may not be consistent, so please read the changelog of that particular version where you there will be pointed out the next working version to install.
Disclaimer: This library takes inspiration form the Colorful Hearts mod, from which I used the rendering system to understand the rendering of the hearts, after that a revisited the rendering system to match my needs. Even though there was no collaboration, i respect the license system and therefore i want to credit the amazing job of other developers that let their mod open source and that made this one possible. Here is an insight of the Colorful Hearts:
- Mod name: Colorful Hearts [-> Link to the MOD]
- Mod License: MIT license (on 16/06/2025 for 1.21.1)
- Mod author: Terrails [-> Link to his PROFILE]

This Library allows developers to easily access the render health bar system, overriding textures and hearts behavours.
It is possible to change the behavior and textures of hearts and the health bar, dynamically and, with a little setup, also simply. The library provides some effects that can be activated, thus changing the appearance of the hearts, so that you can easily test them. Finally, textures are provided that can be used for testing or to create your desired heart bar.
--- The full wiki is available! (Needs a re-check, to know more read heartdev-1.0.5 changelog)
|| For any bug or concerns, please post a comment on the CurseForge comments page, describing the bug, || the Minecraft version and the NeoForge version (if possible). I'll be fixing the bug as soon as possible!!
|| If you want this library to be available on multiple versions, pls write a comment asking that particular || verion, since i will probably only update the mod for the main versions availble, by default.
