Implementations

impl PhysicsWorld2D

Implements body management and simulation for PhysicsWorld2D.

pub fn with_config(config: PhysicsConfig) -> PhysicsWorld2D

Creates a new physics world with the given configuration.

Arguments

• PhysicsConfig - The simulation configuration.

Returns

• PhysicsWorld2D - The new world.

pub fn add_body(&mut self, body: RigidBody2D)

Adds a rigid body to the world.

Arguments

• RigidBody2D - The body to add.

pub fn remove_body(&mut self, id: u64)

Removes the body with the given ID.

Arguments

• u64 - The ID of the body to remove.

pub fn get_body(&self, id: u64) -> Option<&RigidBody2D>

Returns a reference to the body with the given ID.

Arguments

• u64 - The body ID.

Returns

• Option<&RigidBody2D> - The body reference, if found.

pub fn get_body_mut(&mut self, id: u64) -> Option<&mut RigidBody2D>

Returns a mutable reference to the body with the given ID.

Arguments

• u64 - The body ID.

Returns

• Option<&mut RigidBody2D> - The mutable body reference, if found.

impl PhysicsWorld2D

Implements simulation stepping and collision resolution for PhysicsWorld2D.

pub fn step(&mut self, delta_time: f64)

Performs one physics simulation step using semi-implicit Euler integration.

Applies gravity to dynamic bodies, integrates velocity from accumulated forces, applies damping, integrates position, and resolves collisions.

Arguments

• f64 - The fixed delta time in seconds.

Trait Implementations

impl Clone for PhysicsWorld2D

fn clone(&self) -> PhysicsWorld2D

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PhysicsWorld2D

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

Formats the value using the given formatter.

impl Default for PhysicsWorld2D

Implements Default for PhysicsWorld2D as an empty world.

fn default() -> PhysicsWorld2D

Returns the “default value” for a type.

impl PartialEq for PhysicsWorld2D

fn eq(&self, other: &PhysicsWorld2D) -> bool

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for PhysicsWorld2D

impl Updatable for PhysicsWorld2D

Forwards PhysicsWorld2D::step through the Updatable trait so that physics worlds participate in the same update loop as entities, animators, and scene managers. The inherent PhysicsWorld2D::step method is the canonical implementation; this impl exists purely for trait dispatch. The inherent call resolves first when both are in scope, so there is no recursion.

fn update(&mut self, delta_time: f64)

Advance the object’s internal state by the given delta time.
