Bevy Collision 2D

A simple Bevy library designed for 2D kinematic-body collision. Support is only planned for points and AABBs. Uses glam vector types like Bevy does.

Supported Functionality

See the pinned issue for current progress in planned functionality.

Usage

This library is designed to be as simple as possible. Take note that AABB representation is different than other libraries. Below is an example of how collision is detected:

use bevy_collision_2d::prelude::*;
use glam::{IVec2, Vec2};

let point = KinematicBody::point(
    Vec2::ZERO, // Position
    Vec2::ONE,  // Motion
);
let aabb = KinematicBody::aabb(
    Vec2::ONE,          // Size
    Vec2::new(0.5, 0.), // Position
    Vec2::ZERO,         // Motion
);
let actual = point.collision(&aabb);
let expected = Some(Collision {
    position: Vec2::splat(0.5),
    normal: Some(-IVec2::X), // Relative to the body passed to `collision()`
});
assert_eq!(actual, expected);
