Hunger

Various things in this modpack can affect hunger and exhaustion. First, I'll go over the vanilla behaviors:

• Hunger decreases by 1 when exhaustion reaches 4. You can gain more than 4 exhaustion in a single event and none of it gets ignored; if you suffer 12 exhaustion from one event, your hunger bar will decrease by 3.
• Your hunger bar has a maximum value of 20.
• Saturation has a maximum value equal to your current hunger (up to 20). Certain effects can reduce your hunger without reducing saturation, which can leave saturation higher than your hunger in these instances.
• Exhaustion only increases when performing certain events:
  • Sprinting: +0.1 per meter
  • Swimming: +0.01 per meter
  • Mining: +0.005 per block broken
  • Jumping: +0.05 per jump
  • Attacking: +0.1 per attack landed
  • Taking damage: +0.1 per distinct instance of damage being received
  • Jumping while sprinting: +0.2 per jump
  • The hunger potion effect increases exhaustion by +0.1 per second per level. Eating rotten flesh causes Hunger 1 for 30 seconds (3.0 exhaustion), and eating raw puffer fish causes Hunger 3 for 15 seconds (4.5 exhaustion).

Mods can have various effects on hunger. For example, the metabolic generator from Cyberware reduces hunger by 1 point per second when generating energy, or the Bigger Stomach effect from Astral Sorcery decreases exhaustion by 0.01 per tick (or 0.2 per second).
