🥐 Sleep Hunger Drain Mechanics

Sleeping overnight in real life burns calories; waking up in Minecraft should naturally make you ready for breakfast.

When truesleep:sleep_hunger is enabled (default: ON), sleeping players experience a subtle, balanced food exhaustion drain during time warp.

📐 Food Exhaustion Equation

$$\text{exhaustion} = \text{strideTicks} \times 0.0008\text{ food exhaustion points}$$

• Over a standard $10{,}000\text{-tick}$ night ($12542 \to 24000$), total exhaustion is: $$\text{Total Exhaustion} = 10000 \times 0.0008 = 8.0\text{ points} = 2.0\text{ hunger points (1 drumstick)}$$
• If sleeping through a full $12{,}000\text{-tick}$ cycle, you will consume approximately $3.0\text{ to }4.0\text{ hunger points}$.

🛡️ Starvation Safety Floor

True Sleep will NEVER starve a sleeping player to death. The drain automatically halts when the player's food level reaches 6 points (3 drumsticks):

if (player.getFoodData().getFoodLevel() <= 6) return;

🫧 Pulmonary Stasis (Drown Immunity)

In vanilla Minecraft, placing a bed underwater or getting submerged by flowing water while sleeping causes rapid oxygen loss, resulting in drowning damage and forced bed ejection.

When truesleep:drown_immunity is enabled (default: ON), True Sleep activates Pulmonary Stasis:

• Intercepts Entity.baseTick() for sleeping players.
• Refills air supply continuously to getMaxAirSupply() ($300\text{ air ticks}$).
• Allows players to enjoy scenic underwater base naps without drowning!

if (serverLevel.getGameRules().get(TrueSleepRules.DROWN_IMMUNITY)) {
    this.setAirSupply(this.getMaxAirSupply());
}
