有没有办法在 bevy 游戏引擎中检测 Sprites 的碰撞？

Question

目前我正在使用两个物体（彗星和飞船）的位置来检测它们是否发生碰撞。

fn collision_detection(
    comets: Query<&Transform, With<Comet>>,
    mut ships: Query<(&Transform, &mut ShipStatus), With<Ship>>,
) {
    for comet in comets.iter() {
        for (ship, mut status) in ships.iter_mut() {
            if comet.translation.x < ship.translation.x + 80.0 && comet.translation.y < ship.translation.y + 80.0
            && comet.translation.x > ship.translation.x - 80.0 && comet.translation.y > ship.translation.y - 80.0 {
                status.dead = true;
            }
        }
    }
}

但必须有更好的方法来做到这一点。

Bevy 目前没有完整的碰撞系统。除非它在 introductory page 创建后的几个月内得到扩展：

Physics

Many games require collision detection and physics. I'm planning on building a plug-able physics interface with nphysics / ncollide as the first backend.

幸运的是，这个简单的示例实际上是由 bevy::sprite::collide_aabb::collide 提供的，它可以进行简单的 AABB 碰撞检测。

use bevy::sprite::collide_aabb::collide;

let ship_size = Vec2::new(80.0, 80.0);
let comet_size = Vec2::new(0.0, 0.0);
for comet in comets.iter() {
    for (ship, mut status) in ships.iter_mut() {
        if collide(ship.translation, ship_size, comet.translation, comet_size).is_some() {
            status.dead = true;
        }
    }
}

Is there a way of detecting collision of Sprites in the bevy game engine?
