Hydration Logic adds a realistic "Thirst" mechanic to your survival world. Powered entirely by the Script API, this addon is extremely lightweight and causes minimal server lag compared to command-block based systems.
A lightweight, vanilla-like hydration addon powered by the Script API.
Survival gets a new layer of realism — track your water intake, manage dehydration, and choose how you hydrate. Works great on its own, and pairs seamlessly with Thermologic for a full body-simulation survival experience.
💧 Main Features
1. Hydration Gauge
Your hydration level is shown on the action bar.
Decay: Thirst decreases over time. Sprinting and being in the Nether increase the rate.
Dehydration: At 0%, you suffer Slowness and Nausea, and take gradual damage.
Creative / Spectator: Gauge is hidden and thirst does not decrease.
2. Water Quality (Dirty vs. Purified)
Direct drinking: Sneak while submerged in a water source (empty hands only) to drink directly. Risk of Poison or severe Nausea.
Water Bottle: Restores hydration but may cause food poisoning (Hunger).
Purified Water (Distilled): Smelt a Water Bottle in a furnace. Restores 50% hydration safely with no illness risk.
3. Drinks & Food
🥛 Milk Bucket — +20%
🧪 Purified Water — +50%
💧 Water Bottle — +30% (poisoning risk)
🍲 Stews & Soups — +25%
🍎 Fruits — +15%
🫐 Berries — +5%
4. Difficulty Settings
/hydration:diff easy — Thirst stays at 100%
/hydration:diff normal — 0.5× decay (relaxed)
/hydration:diff hard — 1.0× decay (standard)
/hydration:diff extreme — 1.5× decay (brutal)
5. Language
Auto-detects English or Japanese from your client language on first join.
/hydration:lang en or /hydration:lang ja to switch manually.
When Thermologic is installed, language changes sync between both addons.
🔗 Thermologic Integration (Optional)
Install alongside Thermologic for cross-mechanics:
High body temperature accelerates thirst loss
Dehydration reduces sweating and shivering efficiency
Drinking gradually cools core body temperature
Combined action bar: Hydration | Body Temperature
Both addons work independently — no hard dependency required.
