Struct RayHits

pub struct RayHits { /* private fields */ }

Contains the hits of a ray cast by a RayCaster.

The maximum number of hits depends on the value of max_hits in RayCaster.

Order

By default, the order of the hits is not guaranteed.

You can iterate the hits in the order of distance with iter_sorted. Note that this will create and sort a new vector instead of the original one.

Note: When there are more hits than max_hits, some hits will be missed. If you want to guarantee that the closest hit is included, set max_hits to one.

Example

use avian3d::prelude::*;
use bevy::prelude::*;

fn print_hits(query: Query<&RayHits, With<RayCaster>>) {
    for hits in &query {
        // For the faster iterator that isn't sorted, use `.iter()`
        for hit in hits.iter_sorted() {
            println!("Hit entity {} with distance {}", hit.entity, hit.distance);
        }
    }
}

Implementations

impl RayHits

pub fn as_slice(&self) -> &[RayHitData]

Returns a slice over the ray hits.

pub fn len(&self) -> usize

Returns the number of hits.

pub fn is_empty(&self) -> bool

Returns true if the number of hits is 0.

pub fn clear(&mut self)

Clears the hits.

pub fn iter(&self) -> Iter<'_, RayHitData>

Returns an iterator over the hits in arbitrary order.

If you want to get them sorted by distance, use iter_sorted.

pub fn iter_sorted(&self) -> IntoIter<RayHitData>

Returns an iterator over the hits, sorted in ascending order according to the distance.

Note that this creates and sorts a new vector. If you don’t need the hits in order, use iter.
