Hydration System
This mechanic introduces two new player stats: hydration and "quenchness". Hydration is similar to hunger, damaging the player (and potentially killing them if in hard mode) when too low. "Quenchness" is instead similar to saturation, indicating how quenched a player's thirst is, and not directly shown on the thirst bar.
The thirst bar is located above the hunger bar, and indicates a player's level of hydration.
If AppleSkin is installed, the bar will also show the exhaustion and "quenchness" levels.
A player will get thirsty by performing physical activities like sprinting, swimming, jumping, or mining blocks. The speed at which a player gets thirstier is influenced by the temperature and humidity of the biome the player is currently in. To learn more, visit the temperature page.
Hydration will also deplete if the player is healing.
Hydration can be restored by drinking water-based liquids or (in smaller quantities) by eating foods that contain water (mostly fruits, stews, and some vegetables).
By default, a player can quench their thirst just by consuming items, but an option in the config allows for the player to be able to shift right-click a running or still water block, and restore a small amount of hydration.
If the player has the Fire Resistance effect, they will not lose hydration. Wearing Fire Protection armor also slows it down.
