I need some help with a Fractional Heart System?

Question

I'm trying to create a heart system that displays my health with 5 hearts and reduces in fractions every time. I want to make the maximum health 200 so that means every quarter is 10 and every heart is 40.

I know that you have to reference 5 different heart sprites by using 5 cases and assigning each one then when generating them you just use a prefab to spawn them in a horizontal layout group, but that's as far as my knowledge goes, and it's more I know how it works but not how to code it.

Thank you in advance for any help I get:)

You mean a system like this? Over there I made a WebGL example.

That is sort of the system I want, But it's More Where I have 5 hearts throughout the whole game and each heart stores 40 health and 10 for every section of the heart. I've made 5 sprites for the game with different amounts of the heart missing: Full, Three-quarters, Half, Quarter, Empty. I followed a tutorial before on how to make a system, but it adds more hearts every time and calculates the hearts in an annoying way and my brain isn't big enough to program a new version of it. I understood the part where he used a switch statement and enums to switch the heart if it goes into a value from 0 to 4, but I don't understand how to program the drawing of the hearts and updating it when hurt. I know the basic principle, but I'm not able to program it on my own.

It should all work in fundamentally the same manner, but you would just apply one more multiplication/division to account for your fraction-of-a-fraction heart values.

 int healthPerPartialHeart = 10;
 int partsPerHeart = 4;
 
 // ...
 
 int fullHeartCount = hp / (healthPerPartialHeart * partsPerHeart);
 int spriteIndex = (hp / healthPerPartialHeart) % partsPerHeart;
 
 // Example: 200 hp
 // fullHeartCount(5) = hp(200) / (10 * 4) = 200 / 40 = 5
 // irrelevant sprite index at full health
 // spriteIndex(0) = (hp(200) / 10) % 4 = 20 % 4 = 0
 
 // Example: 134 hp
 // fullHeartCount(3) = hp(134) / (10 * 4) = 134 / 40 = 3
 // spriteIndex(1) = (hp(134) / 10) % 4 = 13 % 4 = 1
