avian3d::spatial_query

Struct SpatialQuery

Source 
pub struct SpatialQuery<'w, 's> {
    pub query_pipeline: ResMut<'w, SpatialQueryPipeline>,
    /* private fields */
}
Expand description

A system parameter for performing spatial queries.

§Methods

For simple raycasts and shapecasts, consider using the RayCaster and ShapeCaster components that provide a more ECS-based approach and perform casts on every frame.

§Example

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

fn print_hits(spatial_query: SpatialQuery) {
    // Ray origin and direction
    let origin = Vec3::ZERO;
    let direction = Dir3::X;

    // Configuration for the ray cast
    let max_distance = 100.0;
    let solid = true;
    let filter = SpatialQueryFilter::default();

    // Cast ray and print first hit
    if let Some(first_hit) = spatial_query.cast_ray(origin, direction, max_distance, solid, &filter) {
        println!("First hit: {:?}", first_hit);
    }

    // Cast ray and get up to 20 hits
    let hits = spatial_query.ray_hits(origin, direction, max_distance, 20, solid, &filter);

    // Print hits
    for hit in hits.iter() {
        println!("Hit: {:?}", hit);
    }
}

Fields§

§query_pipeline: ResMut<'w, SpatialQueryPipeline>

The SpatialQueryPipeline.

Implementations§

Source§

impl SpatialQuery<'_, '_>

Source

pub fn update_pipeline(&mut self)

Updates the colliders in the pipeline. This is done automatically once per physics frame in PhysicsStepSystems::SpatialQuery, but if you modify colliders or their positions before that, you can call this to make sure the data is up to date when performing spatial queries using SpatialQuery.

Source

pub fn cast_ray( &self, origin: Vector, direction: Dir3, max_distance: Scalar, solid: bool, filter: &SpatialQueryFilter, ) -> Option<RayHitData>

Casts a ray and computes the closest hit with a collider. If there are no hits, None is returned.

§Arguments
  • origin: Where the ray is cast from.
  • direction: What direction the ray is cast in.
  • max_distance: The maximum distance the ray can travel.
  • solid: If true and the ray origin is inside of a collider, the hit point will be the ray origin itself. Otherwise, the collider will be treated as hollow, and the hit point will be at its boundary.
  • filter: A SpatialQueryFilter that determines which entities are included in the cast.
§Example
use avian3d::prelude::*;
use bevy::prelude::*;

fn print_hits(spatial_query: SpatialQuery) {
    // Ray origin and direction
    let origin = Vec3::ZERO;
    let direction = Dir3::X;

    // Configuration for the ray cast
    let max_distance = 100.0;
    let solid = true;
    let filter = SpatialQueryFilter::default();

    // Cast ray and print first hit
    if let Some(first_hit) = spatial_query.cast_ray(origin, direction, max_distance, solid, &filter) {
        println!("First hit: {:?}", first_hit);
    }
}
Source

pub fn cast_ray_predicate( &self, origin: Vector, direction: Dir3, max_distance: Scalar, solid: bool, filter: &SpatialQueryFilter, predicate: &dyn Fn(Entity) -> bool, ) -> Option<RayHitData>

Casts a ray and computes the closest hit with a collider. If there are no hits, None is returned.

§Arguments
  • origin: Where the ray is cast from.
  • direction: What direction the ray is cast in.
  • max_distance: The maximum distance the ray can travel.
  • solid: If true and the ray origin is inside of a collider, the hit point will be the ray origin itself. Otherwise, the collider will be treated as hollow, and the hit point will be at its boundary.
  • filter: A SpatialQueryFilter that determines which entities are included in the cast.
  • predicate: A function called on each entity hit by the ray. The ray keeps travelling until the predicate returns false.
§Example
use avian3d::prelude::*;
use bevy::prelude::*;

#[derive(Component)]
struct Invisible;

fn print_hits(spatial_query: SpatialQuery, query: Query<&Invisible>) {
    // Ray origin and direction
    let origin = Vec3::ZERO;
    let direction = Dir3::X;

    // Configuration for the ray cast
    let max_distance = 100.0;
    let solid = true;
    let filter = SpatialQueryFilter::default();

    // Cast ray and get the first hit that matches the predicate
    let hit = spatial_query.cast_ray_predicate(origin, direction, max_distance, solid, &filter, &|entity| {
        // Skip entities with the `Invisible` component.
        !query.contains(entity)
    });

    // Print first hit
    if let Some(first_hit) = hit {
        println!("First hit: {:?}", first_hit);
    }
}
Source

pub fn ray_hits( &self, origin: Vector, direction: Dir3, max_distance: Scalar, max_hits: u32, solid: bool, filter: &SpatialQueryFilter, ) -> Vec<RayHitData>

Casts a ray and computes all hits until max_hits is reached.

Note that the order of the results is not guaranteed, and if there are more hits than max_hits, some hits will be missed.

§Arguments
  • origin: Where the ray is cast from.
  • direction: What direction the ray is cast in.
  • max_distance: The maximum distance the ray can travel.
  • max_hits: The maximum number of hits. Additional hits will be missed.
  • solid: If true and the ray origin is inside of a collider, the hit point will be the ray origin itself. Otherwise, the collider will be treated as hollow, and the hit point will be at its boundary.
  • filter: A SpatialQueryFilter that determines which entities are included in the cast.

Converts Rc<Trait> (where Trait: Downcast) to Rc<Any>, which can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.
Source§

fn as_any(&self) -> &(dyn Any + 'static)

Converts &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.
Source§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Converts &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

Source§

fn into_any_send(self: Box<T>) -> Box<dyn Any + Send>

Converts Box<Trait> (where Trait: DowncastSend) to Box<dyn Any + Send>, which can then be downcast into Box<ConcreteType> where ConcreteType implements Trait.

where T: Any + Send + Sync,

Source§

fn into_any_sync(self: Box<T>) -> Box<dyn Any + Sync + Send>

Converts Box<Trait> (where Trait: DowncastSync) to Box<dyn Any + Send + Sync>, which can then be downcast into Box<ConcreteType> where ConcreteType implements Trait.
Source§

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send>

Converts Arc<Trait> (where Trait: DowncastSync) to Arc<Any>, which can then be downcast into Arc<ConcreteType> where ConcreteType implements Trait.

where A: Any,

Source§

fn is<T>() -> bool
