Struct FoodData 

pub struct FoodData {
    pub food_level: i32,
    pub saturation_level: f32,
    pub exhaustion_level: f32,
    pub tick_timer: i32,
}

Tracks a player’s hunger, saturation, and exhaustion state. One instance is stored per player behind a SyncMutex.

Fields

food_level: i32

Current food level (0–20). Displayed as the hunger bar on the client.

saturation_level: f32

Saturation buffer — consumed before the food level drops.

exhaustion_level: f32

Accumulated exhaustion from actions (sprinting, jumping, damage, …).

tick_timer: i32

Internal tick counter shared between regeneration and starvation logic.

Implementations

impl FoodData

pub const fn new() -> Self

Creates a new FoodData with default values (full hunger bar).

pub const fn needs_food(&self) -> bool

Returns true if the player’s food level is below maximum and they could benefit from eating.

pub const fn has_enough_food(&self) -> bool

Returns true if the player has enough food to perform exhaustive maneuvers (for example sprinting).

pub fn add_exhaustion(&mut self, amount: f32)

Adds exhaustion from an action (sprinting, jumping, taking damage, …). The value is clamped so exhaustion_level never exceeds 40.

fn add(&mut self, food: i32, saturation: f32)

Applies food and saturation

pub fn eat(&mut self, nutrition: i32, saturation_modifier: f32)

Applies the nutrition from eating food, given a saturation modifier.

pub fn tick( &mut self, difficulty: Difficulty, natural_regen: bool, current_health: f32, max_health: f32, ) -> FoodTickResult

Runs one tick of the hunger system. Returns a FoodTickResult describing what happened this tick so the caller (Player::tick) can apply healing or starvation damage

Trait Implementations

impl Clone for FoodData

fn clone(&self) -> FoodData

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FoodData

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FoodData

fn default() -> Self

Returns the “default value” for a type.
