A complete survival overhaul that adds two interconnected systems to your world: thirst and temperature. Stay hydrated, dress for the weather, and watch your environment, every biome, every block, and every decision matters.
Features
🌡️ Temperature System
Your body temperature changes dynamically based on the world around you. A thermometer HUD displays beside your water bar, shifting through five states: Very Cold, Cold, Normal, Hot, and Very Hot.
What affects your temperature:
- Biome detection — The system scans 100+ block types around you to determine the biome temperature. Deserts and badlands scorch you, snowy tundras freeze you, and forests keep things mild.
- Day/night cycle — Midday is warmest, night is coldest. Plan your expeditions accordingly.
- Altitude — High mountains are freezing. Deep underground is warmer.
- Shelter — A roof over your head insulates you, pulling temperature back toward normal.
- Heat sources — Campfires, lava, torches, furnaces, and fire all radiate warmth with realistic distance falloff.
- Water exposure — Swimming makes you colder over time. Deeper water is worse. Stay in too long and hypothermia sets in progressively.
- Armor — Leather is the best cold-weather gear. But heavy metal armor in a desert? That traps heat and makes you even hotter.
- Dimension-aware — The Nether is always scorching. The End is always cold.
Temperature States:
- Very Cold — Slowness II, mining fatigue, freezing damage over time. A frost overlay covers your screen.
- Cold — Slowness I. A warning to find warmth.
- Normal — No effects. You're comfortable.
- Hot — Hunger effect. You're sweating.
- Very Hot — Hunger II, weakness, fire damage over time. A heat overlay fills your screen edges.
Transitions between states are smooth and gradual, no jarring instant swaps.
💧 Thirst System
A thirst bar appears on your HUD alongside the default hunger bar. It depletes as you move, sprint, and jump, faster in hot biomes, slower in cold ones.
How thirst works:
- Movement drains thirst — Walking, sprinting, and jumping all cost water. Sprinting costs nearly double.
- Difficulty scaling — Hard mode drains faster than Easy.
- Climate matters — Deserts drain 60% faster. The Nether drains 2x faster. Snowy biomes slow drain by 40%.
- Healing costs water — When your health regenerates, it uses extra thirst.
- Food hydration — Fruits and soups restore thirst. Melons, berries, apples, stews — they all help. But dry foods like bread, cooked meat, and dried kelp actually make you thirstier.
Dehydration penalties:
- Below 6 thirst: Slowness IV kicks in
- Below 2 thirst: Nausea
- At 0 thirst: You start taking damage
🫗 Water Canteen & Purification
Craft a Water Canteen from leather and string at a crafting table:
Water sources:
- Raw drinking — Sneak + interact (empty hand) near water when thirsty. Restores 7 thirst but risks poison (20% chance) and always gives a brief hunger effect.
- Dirty Canteen — Fill your empty canteen at any water source. Holds 3 drinks (5 thirst each), but dirty water risks poison and hunger effects.
- Purified Canteen — Smelt a dirty canteen in a furnace, campfire, or soul campfire. Same 3 drinks, zero side effects, plus a cooling bonus.
- Purified Water Bottle — Smelt a regular potion (water bottle) for a single-use purified drink worth 10 thirst.
- Cauldrons — Sneak + interact with a water-filled cauldron for emergency drinking (uses one fill level).
Installation
- Download both Resource Pack (RP) and Behavior Pack (BP)
- Import both packs into Minecraft Bedrock
- Apply both packs to your world
- Play! The systems activate automatically
Requirements:
- Minecraft Bedrock Edition 1.21.0 or later
Multiplayer: Fully supported. Each player has independent thirst and temperature tracking.
Tips for Survival
- Carry a canteen — It's the difference between life and death in a desert.
- Purify your water — A campfire in the wild can save you from poison.
- Wear leather in the cold — It's the best insulation in the game. Full leather gives more cold protection than full diamond.
- Don't wear iron in the desert — Metal armor traps body heat. Go light or wear leather.
- Build shelter — Any solid roof (not leaves or glass) insulates you.
- Use campfires — They warm nearby players and can purify your canteen.
- Eat smart — Melon slices and berries hydrate you. Bread and cooked meat make you thirstier.
- Watch the clock — Travel during mild hours. Night in a snowy biome can kill.
