Survival mechanic
Regeneration timing
Natural healing happens every 0.5 seconds at full hunger with saturation left and every 4 seconds at 18 hunger or more, and both speeds share one timer.
Rules
| Game rule | Natural healing only happens while the Regenerate health game rule is on. |
| Fast healing | At 20 hunger with saturation above 0, an injured player heals every 0.5 seconds (10 ticks). |
| Slow healing | At 18 hunger or more, an injured player heals every 4 seconds (80 ticks). |
| Shared timer | Both speeds and starvation use the same timer. Moving from one to another does not restart it. |
| Exhaustion first | Every tick, exhaustion is charged first. The hunger and saturation left after that decide which healing speed applies. |
| Timer reset | The timer returns to 0 in any tick in which the player is neither healing nor starving, for example at full health. |
