Struct WorldState 

pub struct WorldState { /* private fields */ }

A set of named conditions describing the current state of the world from one agent’s perspective.

Conditions have two flavours:

• Bool — classic GOAP true/false flags.
• Float — numeric values (health, ammo count, distance…) used for richer precondition checking.

Implementations

impl WorldState

pub fn new() -> Self

pub fn set_bool(&mut self, key: &str, value: bool)

pub fn get_bool(&self, key: &str) -> bool

pub fn has_bool(&self, key: &str) -> bool

pub fn set_float(&mut self, key: &str, value: f32)

pub fn get_float(&self, key: &str) -> f32

pub fn has_float(&self, key: &str) -> bool

pub fn satisfies(&self, goal: &WorldState) -> bool

Does self satisfy every condition in goal?

Bool conditions must match exactly. Float conditions in goal are treated as lower bounds — i.e. self.float >= goal.float.

pub fn distance_to(&self, goal: &WorldState) -> usize

Number of unsatisfied conditions from goal. Used as A* heuristic.

pub fn apply(&self, effects: &ActionEffects) -> WorldState

Apply an action’s effects to produce the successor state.

pub fn merge_from(&mut self, other: &WorldState)

Merge another state into self, overwriting on conflict.

pub fn is_empty(&self) -> bool

True if this state has no conditions at all.

Trait Implementations

impl Clone for WorldState

fn clone(&self) -> WorldState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WorldState

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

Formats the value using the given formatter.

impl Default for WorldState

fn default() -> WorldState

Returns the “default value” for a type.

impl PartialEq for WorldState

fn eq(&self, other: &WorldState) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
