Physiology

Physiology – A Survival Simulation Mod（1.0.6-Fix）

Physiology adds a complete bodily function system to Minecraft. It’s not just about eating and fighting anymore — now you have to manage your character’s natural processes too!

—– Core Features —–

1. Gender Selection 🚻

Players choose their gender when first entering the world (or pick Random if you don’t want to decide).

    Effects
1. Urination posture (males can stand; females must crouch or sit)
2. Urine/stool gain rates (males gain more, females gain less)
3. Excretion speed (males excrete faster, females slower)

2. Urination System 💧

Drinking various beverages grants urine points:

1. Vanilla water bottle / any potion: +3 urine
2. Milk bucket: +5 urine
3. Honey bottle: +2 urine
4. Full canteen (ThirstCanteen compat: leather / dragon bottle / military): +5 urine
5. Pee Bottle: +3 urine

Natural accumulation: Male: +1 every 30s, Female: +1 every 45s.

Press N to urinate; cap is 50. (PS: press N again to interrupt; females are interrupted when standing up.)

3. Defecation System 💩

Every food item you eat accumulates stool in your gut.

Formula: ΔStool (male) = min(M·H·(1+S), 35)·D and ΔStool (female) = min(0.5·M·H·(1+S), 35)·D
H = food hunger value
S = food saturation modifier
M = stoolGainMultiplier config (default 1.0)
D = diarrhea coefficient: 1.5 with Diarrhea, otherwise 1

Press P to defecate; press P again during defecation to push harder. I’m sure you can read the formula, right? 喵

After defecating you get the Stench buff, which slows the player down (cleaning methods covered below).

4. Hygiene Facilities 🚽

Most require sitting on them to use.

1. Bedpan: 9-slot container for poop, 25 materials (wood / stone / metal & gems / 16 colored concrete). Better materials allow more per slot (1 → 9).
2. Chamber Pot: right-click to sit; becomes dirty after use; clean with a shovel.
3. Toilet: sneak-right-click to flip the lid; can only sit when open; becomes dirty after use; flush to restore.
4. Squat Toilet: stand on it and press P; becomes dirty after use; flush to restore.
5. Pit Toilet: stand on it to defecate; poop disappears instantly.
6. Urinal: wall-mounted, male-only.
7. Unfired versions: decorative only, no function (PS: mid-game stopgaps 喵).

There are also some unorthodox blocks you can use: composter, brewing stand, lava cauldron, End Portal Frame, upward-facing dispenser/dropper, hopper/smoker/barrel — each with its own feedback and achievement.

5. Hygiene System 🧻

Defecating gives you the Stench buff, which must be wiped off with cleansing items.

1. Leaf — crafted from leaves or dropped by breaking leaves; costs 1 HP
2. Tree Bark — obtained from stripping logs; costs 2 HP
3. Rock — crafted from cobblestone; costs 4 HP
4. Hemp Rope — crafted (string + grass); costs 1 HP
5. Grass Paper — crafted (9 grass)
6. Fabric — crafted (string + wool)
7. Toilet Paper + colored toilet paper — crafted from 3 paper; dye + 8 toilet papers to color
8. Toilet Token — crafted (stick + fabric)

    Washing dirty items
Washable: dirty leaf, dirty rock, dirty tree bark, dirty fabric, dirty toilet token, dirty hemp rope
Not washable: all dirty toilet paper, dirty grass paper (single-use, gone once dirty)
Wash methods: right-click a water source / water cauldron, hold a water bottle in your offhand and right-click, or drop them into water.

6. Resource Recovery 🌱

1. Poop can be right-clicked onto a composter to raise its level.
2. Poop can be used as a dye/fuel.
3. Poop can be used in brewing.
4. Urine Pot can fertilize crops.
5. Pee Bottle is drinkable / Dry Shit is edible (but I really don’t recommend it).
