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
