@NullMarked
public class CollisionDetectionSystem
extends technology.sola.ecs.EcsSystem

The CollisionDetectionSystem class is a EcsSystem implementation that handles checking if a World has any Entity with ColliderComponents that are colliding with each other. If a collision is detected either a SensorEvent or a CollisionEvent will be emitted depending on if either collider ColliderComponent.isSensor() or not.
