Struct WorldCcdConfig 

#[non_exhaustive]
pub struct WorldCcdConfig { /* private fields */ }

The setting for continuous collision in the world step (see the module documentation of world_ccd for the method).

Built with Self::new (off) or Self::on and adjusted with the with_* methods; the fields cannot be written from outside the crate.

Examples

use alice_physics::{Fix128, PhysicsConfig, PhysicsWorld, WorldCcdConfig};

let mut world = PhysicsWorld::new(PhysicsConfig::default());
assert!(!world.continuous_collision().is_enabled());

world.set_continuous_collision(WorldCcdConfig::on().with_motion_threshold(Fix128::from_ratio(1, 2)));
assert!(world.continuous_collision().is_enabled());
assert_eq!(world.continuous_collision().motion_threshold(), Fix128::from_ratio(1, 2));

Implementations

impl WorldCcdConfig

pub const fn new() -> Self

Off, with the default threshold 1 (a body is swept when it moves more than its collision radius in one substep).

pub const fn on() -> Self

On, with the default threshold 1.

pub const fn with_enabled(self, enabled: bool) -> Self

The same setting, switched on or off.

pub const fn with_motion_threshold(self, threshold: Fix128) -> Self

The same setting with another threshold, in collision radii: a body is swept when its displacement in one substep is longer than threshold × radius. A threshold ≤ 0 sweeps every moving body.

pub const fn is_enabled(&self) -> bool

Whether the step sweeps fast bodies.

pub const fn motion_threshold(&self) -> Fix128

The threshold, in collision radii.
