bevy_spatial

A bevy plugin to track your entities in spatial indices and query them.

Currently implemented features: |Feature|Description| |-|-| |kdtree (default) |KD-Tree for spatial lookups which is fully recreated on update, but fast to recreate. Works well in most situations.|

```rust use bevy_spatial::{AutomaticUpdate, KDTree3, TransformMode, SpatialAccess};

[derive(Component, Default)]

struct TrackedByKDTree;

fn main() { App::new() .addplugin(AutomaticUpdate::::new() .withfrequency(Duration::fromsecsf32(0.3)) .withtransform(TransformMode::GlobalTransform)) .addsystem(use_neighbour); // ... }

type NNTree = KDTree3; // type alias for later

// spawn some entities with the TrackedByKDTree component

fn useneighbour(tree: Res){ if let Some((pos, entity)) = tree.nearestneighbour(Vec3::ZERO) { // pos: Vec3 // do something with the nearest entity here } } ```

For more details on usage see Examples

wasm caveats: the rayon acceleration for kdtree is disabled on wasm, making it a bit slower.
