Implementations

impl PhysicsWorld2D

pub fn new() -> Self

pub fn zero_gravity() -> Self

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

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

pub fn add_joint(&mut self, joint: Joint) -> JointId

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

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

pub fn step(&mut self, dt: f32)

Advance the simulation by dt seconds.

pub fn raycast(&self, origin: Vec2, dir: Vec2, max_dist: f32) -> Vec<RayHit>

Cast a ray through the world, returning all hits sorted by distance.
