Hydration Logic
- By
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 enor/hydration:lang jato 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.
⚠ Requirements
- Enable the Beta APIs experiment in world settings.
- Minimum engine version: 1.21.50
- Behavior Pack + Resource Pack must both be applied.
