Blue Addicts

Blue Addicts is a chemistry-inspired mod that introduces a unique and slightly questionable way to earn your emeralds. Drawing inspiration from underground science fiction shows like Breaking Bad and modern masterpieces like Schedule 1, this mod lets you enter the lucrative world of selling overpriced products to your local village. You will need to place down a cooking station for a villager, so they can get the new profession.

Progression

To kick off your empire, you’ll need to locate one of the two (for now) new structures where you can get your hands on acid and cold tablets. If you don't like searching for structures, worry not the Cartographer will sell you maps to these structures at level one. Oh, and since I know you YEARN FOR THE MINES you’ll need to go caving to find some phosphorus ore, heat it up into red phosphorus in a furnace or blast furnace, and grind it into powder using a blender. Once you’ve got all your ingredients, it’s time to cook.

Craft a cooking station and a metal tray, toss in one of each ingredient, and watch the colored pH bar at the bottom. Your goal is to hit that sweet spot a red-orange hue by balancing the ingredients just right.

But beware: too much red phosphorus and your mixture might get a little too reactive (if you know I'm saying). Too little, and your product won’t be worth a single emerald. If you're having issues understanding how it works, here's the math behind the scenes:

// Differences from the correct values
int acidDiff = acidCount - acidNeeded;
int phosphorusDiff = phosphorusCount - phosphorusNeeded;
int pseudoDiff = pseudoCount - pseudoNeeded;

// Enforce a minimum acid threshold
boolean acidSufficient = acidCount >= acidNeeded;

// Distance from correct input (larger = worse)
float totalDeviation = 
    Math.abs(acidDiff) * 1.0F +      // acid has highest effect
    Math.abs(pseudoDiff) * 0.6F +    // pseudo medium effect
    Math.abs(phosphorusDiff) * 0.4F; // phosphorus smallest effect

// Base pH is higher if acid is insufficient
float basePh = acidSufficient ? 1.0F : 3.0F;

// pH increases with deviation
float pH = basePh + totalDeviation * 0.5F;

Your target pH is 1.

Some information

This is my first Minecraft mod, I am by no means a 3D modeler or drawer so I apologize in advance for the horrible looking models and textures. More features may be added over time, and I’ll try to patch any bugs.
