Advanced Thirst & Temperature System

This comprehensive datapack adds realistic thirst and temperature mechanics to Minecraft that you control, creating an immersive survival experience with dynamic environmental effects.

Compatibility

This is compatable with vanilla and ALL loaders(Forge, Fabric, etc.)
Server side only(People do not need to download anything)
Works with Geyser
Works on single/multiplayer worlds
Uses all vanilla mechanics

Resource Pack Added! (Optional)

Lowers thirst bar closer and right above armor and bubbles

Must Toggle on/off using commands(By default it will not be enabled)

/trigger kht_display_toggle set (1 or 2) (Changes @s)
/trigger kht_master_display set (1 or 2) (Changes @a)(kht_dmin tag needed)
1 = Resource Pack
2 = Vanilla
/tag add <yourname> kht_admin (sets admin for thirst pack)
If you set it with master_display then it will also save it that way until individuals change it with the kht_display_toggle. So it would require everyone to have the resource pack or toggle it back to default. If you just want it to be for you then just use kht_display_toggle. The setup/installation will be at the bottom of this text document.

Core Features

New Items

Dirty Water - obtain by filling a glass bottle from any water source.
Water is now needed to be boiled from the furnace.

Thirst System:

20-bar thirst meter that depletes over time
Takes 53minutes to deplete
Water bottles restore 7 thirst bars
Melon slice restores 1 thirst bar
Dehydration causes hunger, slowness, mining fatigue, and damage

Dynamic Temperature System:

Real-time temperature gauge with 7 levels (Freezing to Molten)
All biomes have realistic temperatures
Day/night cycles affect temperature (except Nether, End, Deep Dark)
Desert biomes cool significantly at night (-4 temperature)

New Advanced Features

Elevation Effects (Difficulty 5 only):

Elevation 0 - Deep Underground (Y -64 to -1):

Temperature effects: -2 degrees from base temperature
Stable underground environment, protected from weather

Elevation 1 - Sea Level (Y 0 to 39):

Temperature effects: -1 degree from base temperature
Standard coastal and low-altitude areas

Elevation 2 - Hills & Plateaus (Y 40 to 99):

Temperature effects: No change (baseline)
Moderate altitude regions

Elevation 3 - Mountains (Y 100 to 149):

Temperature effects: -1 degree from base temperature
Higher altitude cooling effects begin

Elevation 4 - High Peaks (Y 150+):

Temperature effects: -2 degrees from base temperature
Extreme altitude with significant cooling and faster dehydration
The higher you climb, the colder it gets and the faster you dehydrate due to thin air. This system encourages players to consider altitude when building bases and planning expeditions.

Environmental Interactions:

Shade detection blocks sun's heating effects
Water contact cools you down
Weather affects temperature (rain cools, clear skies heat)
Underground or in sheltor gets rid of sun/weather effects Food Temperature System:
Hot foods (cooked meals, stews) warm you up (5-level scale)
Cold foods (melon, milk) cool you down
Effects last 5 minutes and stack up to maximum levels
Temperature effects reset when timer expires

Dynamic Weather:

Random weather events (rain/thunderstorms)
1% chance every 50 seconds for weather change
Weather lasts 6 minutes before clearing
Weather affects both temperature and shade

Difficulty Levels (Default = 5)

Level 1 - Easy: No temperature effects, 50% slower thirst loss
Level 2 - Casual: No temperature effects, normal thirst rate
Level 3 - Normal: Hot temperatures (5-7) affect thirst rate
Level 4 - Hard: Light hunger effects from extreme cold (1-2), temperature affects thirst
Level 5 - Extreme: Full hunger effects from cold (1-3), elevation system active, all temperature effects

Biome Temperature Classifications

Temperature 7 - MOLTEN (Dark Red): All Nether biomes
Temperature 6 - HOT (Red): Desert, Badlands variants
