Dynamic HUD Elements
This pack is released to be "a modder's resource", but there is also a ready-to-go example which will give you a "sweet-heart" shaped health icon on your screen, which will change in colour and
opacity as player's health decreases. That example also resembles my original intention: to replace the default HUD elements (health, armor, stamina, light, noise) with icons that would rather change colour or opacity instead of a horizontal or vertical straight "bar". By the time I achieved what I wanted, I noticed that I like my own custom "bars", I've previously made for myself, more, so I didn't want to do anything further than the "sweet-heart" example. Still, I thought somebody might find the functionality useful and I decided to release it anyway.
