Thermologic - Advanced Body Temperature Simulation
The most realistic body-temperature survival simulation for Minecraft Bedrock — powered by biophysical thermodynamics.
This is not just a hot/cold gauge. Thermologic simulates core body temperature using real heat-transfer physics. Pair with Hydration Logic for a complete physiological survival experience — both addons work independently.
✨ Main Features
🌍 Dynamic Biome Climate (Köppen Classification)
Air and water temperatures change smoothly via sine curves based on real climate zones.
- Desert: Scorching 47°C days, 14°C nights.
- Jungle: Wet-bulb limit — heatstroke even in shade without water.
- Ice/Snow: Constant sub-zero. Hypothermia without proper gear.
📊 Environment HUD
Real-time action bar display of body temperature, air temp, water temp, and weather. Toggle with /thermo:hud on|off.
💧 Wetness — A Deadly Threat
Water conducts heat 25× faster than air. Wet clothes continue draining body heat via evaporative cooling until you dry off near a campfire.
👕 Armor Insulation (Clo) & Conductivity
Leather insulates well in cold but traps heat in deserts. Metal armor conducts extreme temperatures directly to your skin.
🏃 Realistic Physiological Responses
- Shivering — Auto heat generation in cold; hunger drains faster.
- Sweating — Evaporative cooling in heat; hidden saturation consumed.
- TEF (Digestive Heat) — Eating warms you for several minutes.
- Fever — Food poisoning triggers 39°C fever with severe chills.
- Drinking — Potions and water gradually cool core temperature.
⛺ Environmental Interaction
- Direct sunlight raises body temperature — seek shade or caves.
- Campfires, lava, torches are heat sources; ice and snow are cold sources.
- Huddle with players or animals within 3 blocks for shared warmth.
🔗 Hydration Logic Integration (Optional)
- Combined HUD: Hydration | Body Temperature
- Dehydration reduces sweating and shivering efficiency
- High body temperature accelerates thirst loss
- Drinking gradually cools core temperature (amount-based)
- Language sync between both addons
⚙ Commands
/thermo:lang <en|ja>— Switch language/thermo:diff <easy|normal|hard>— Difficulty (temperature change speed)/thermo:hud <on|off>— Environment HUD (default: on)/thermo:log <on|off>— Debug log (default: off; shows hydration data when paired)
⚠ Debuffs & Lethal Zones
- Hypothermia (< 35.0°C): Shivering hunger drain
- Severe (< 34.0°C): Mining slowdown, slowness
- Hyperthermia (> 38.0°C): Heavy sweating
- Severe (> 39.0°C): Nausea, weakness
- Lethal (≤ 33.0°C or ≥ 40.0°C): Death by hypothermia or heatstroke
⚠ Requirements
- Enable Beta APIs experiment
- Minimum version: 1.21.50
