Detailed Description

Activity adds exhaustion; every exhaustionPerFood of it costs one food point. With at least regenerationFood points the player heals one health point every regenerationInterval seconds, which exhausts as well; at zero food the player loses one health point every starvationInterval seconds, but never below starvationFloor.

Member Function Documentation

bool QcHunger::eat(int points)

Adds the food points of an eaten item. Returns false (nothing eaten) when the player is full.

void QcHunger::exhaust(double amount)

Adds amount of exhaustion (nothing while frozen).

double QcHunger::exhaustion() const

Returns the exhaustion gathered towards the next food point.

int QcHunger::food() const

Returns the food points.

bool QcHunger::frozen() const

Returns whether it is frozen.

See also setFrozen().

void QcHunger::hurt()

Damage resets the regeneration timer.

`[static constexpr]` double QcHunger::minutesForFullBar(double perMetre, double speed)

Returns the minutes of steady movement at speed metres per second with perMetre exhaustion that empty a full food bar.

`[static]` double QcHunger::movementExhaustion(double distance, bool sprinting, bool inWater, bool jumped)

Returns the exhaustion of one movement step: distance metres moved horizontally, sprinting, inWater, and whether the player jumped.

void QcHunger::reset()

Fills the bar and clears the exhaustion and timers.

void QcHunger::restore(int food, double exhaustion)

Takes food and exhaustion from a save, clamped to their ranges.

void QcHunger::setFrozen(bool frozen)

Sets whether it is frozen: while frozen (creative mode) neither exhaustion nor the timers change anything.

See also frozen().

double QcHunger::tick(double dt, double health, double maxHealth)

Advances the timers by dt seconds for a player with health of maxHealth. Returns the health change: +1 for regeneration, a negative amount for starvation, 0 otherwise.

Member Variable Documentation

const double QcHunger::exhaustionPerFood

Exhaustion that costs one food point.

const int QcHunger::maxFood

Food points of a full bar.

const double QcHunger::regenerationExhaustion

Exhaustion one health point of regeneration costs.

const int QcHunger::regenerationFood

Food points at least for regeneration.

const double QcHunger::regenerationInterval

Seconds between two health points of regeneration.

const double QcHunger::starvationDamage

Health one hit of starvation takes.

const double QcHunger::starvationFloor

Starvation never takes health below this.

const double QcHunger::starvationInterval

Seconds between two hits of starvation at zero food.
