Texture pack Spryzeen's Healthbars by Spryzeen

This pack has some addons, the link is inside the pack and here: 
https://www.planetminecraft.com/texture-pack/spryzeen-s-health-bars-compatibility-addons/

Spryzeen's Healthbars allow you to show how much health do mobs have, Never killed accidentaly a villager or pet because
you didn't know they have low health

It's also very useful to know how much health the mobs with which you are fighting have

Features

- Healthbars are emissive, mean you can see it glow in the dark
- This resourcepack uses vanilla core-shaders to improve some features and fix some other bugs
- Healthbars have an animation that gives a 2D apparence
- Supports minimal changes for mobs that has a lot of life, You can see a change in the health bar just attacking an iron golem with your hand

Vanilla Core-Shaders dependency

Shaders are being used to patch some bugs like:
- Healthbar turns red when you hit a mob
- Tropical fish colors overlay healthbar colors too

I don't recommend to use this pack with shaders like BSL, Complementary, Chocapic ETC, because you will lose those features but if you want... you can, health bars will still work
