impacted
2d collision test for game-development in rust (with optional integration and example for bevy)
This provides a low-level "narrow-phase" collision-detection logic, with some integration for the bevy game engine (behind feature flag).
If you want to pair it with a broad-phase, you may look at bvh-arena or broccoli.
Roadmap
- collision test (GJK implementation)
- collision shapes
- circle
- rectangle
- convex-hull
- capsule
- contact generation (EPA implementation)
Usage example
use impacted::{CollisionShape, Transform};
use glam::Vec2; // <-- use any math library you like
// Create a circle
let circle = CollisionShape::new_circle(1.0);
// Create a rectangle
let mut rect = CollisionShape::new_rectangle(4.0, 4.0)
.with_transform(Transform::from_translation(Vec2::new(2.0, 0.0)));
// Test for collision
assert!(circle.is_collided_with(&rect));
You may also look in the examples directory for more complete/concrete usage examples (e.g. using the bevy engine)
