Water & Temperature System Addon pour Minecraft 1.21, 26.40

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

📖 Guide Book

Every player gets a Water & Temperature Guide on their first join, with a chapter on each system: thirst and what drains it, finding and purifying water, the five temperature states, which armor actually keeps you warm, and how weather works.

Lost it? Craft it back from a book and paper at a crafting table.

The difficulty selector lives at the top of the guide.

⚙️ Difficulty

Thirst and temperature have their own difficulty, chosen in the guide book and shared by everyone on the world.

• Easy - Thirst drains slower, hot and cold extremes are pulled in, and freezing and heat damage are halved. Ordinary rain will chill you but won't freeze you.
• Normal - The pack as designed.
• Hard - Thirst drains faster, the extremes are pushed further out, and temperature damage is increased.
• Match World Difficulty - The default. Follows your world's difficulty setting, exactly as previous versions did.

🌡️ 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, lanterns, furnaces, and fire all radiate warmth with realistic distance falloff.
• Weather - Rain, storms and snowfall chill you under open sky, and the longer you stay out the worse it gets.
• 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. Netherite is the exception - it insulates poorly, but it won't cook you.
• Activity - Moving warms you a little. Sprinting warms you more.
• 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.

Fire Resistance blocks heat damage and its debuffs outright - useful for Nether trips.

🌧️ Weather & Getting Wet

Weather is a real threat, not a backdrop.

• Rain builds - Standing under open sky in rain gets colder the longer you stay in it, rather than hitting a cap straight away. A full soak takes around a minute.
• Storms are worse - Thunderstorms chill harder than plain rain, night is colder than day, and rain falling as snow in a cold biome is colder than either.
• You stay wet - Getting under cover doesn't dry you instantly. The chill lingers at half strength while you dry off.
• Fire dries you faster - Standing near a campfire or furnace dries you several times quicker than waiting it out.
• Shelter works - Any solid roof keeps the rain off you entirely. Leaves and glass don't count.

💧 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.
• Climate matters - Deserts drain 60% faster. The Nether drains 2x faster. Snowy biomes slow drain by 40%.
• Temperature matters - Being Very Hot drains thirst 80% faster; being Very Cold slows it 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.
• Difficulty scaling - Set in the guide book, or left to follow your world difficulty.

Dehydration penalties:

• Below 6 thirst: Slowness IV kicks in
• Below 2 thirst: Nausea
• At 0 thirst: You start taking damage

Running dry also makes temperature hit harder in both directions - dehydration and heat feed each other.

🫗 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. The remaining sips are written on the item.
• Purified Canteen - Smelt a dirty canteen in a furnace, campfire, or soul campfire. Same 3 drinks, zero side effects.
• 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).

Any drink also cools you down briefly, which matters more than it sounds in a desert.

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. The difficulty setting is shared across the world.

In-Game Commands

• !status - Your current thirst, temperature, armor insulation, shelter status and difficulty
• !help - A short reference for both systems

Tips for Survival

• Read the guide - It's in your inventory from your first join, and it explains every mechanic in the pack.
• 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.
• Get out of the rain - A storm at night in the open will freeze you, and standing there won't get better on its own.
• Build shelter - Any solid roof (not leaves or glass) insulates you and keeps the rain off.
• Use campfires - They warm nearby players, dry you off fast, 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.
