Information returned about an object detected by a raycast in 2D physics.
A raycast is used to detect objects that lie along the path of a ray and is conceptually like firing a laser beam into the scene and observing which objects are hit by it. The RaycastHit2D class is used by Physics2D.Raycast and other functions to return information about the objects detected by raycasts.
|centroid||The centroid of the primitive used to perform the cast.
|collider||The collider hit by the ray.
|distance||The distance from the ray origin to the impact point.
|fraction||Fraction of the distance along the ray that the hit occurred.
|normal||The normal vector of the surface hit by the ray.
|point||The point in world space where the ray hit the collider's surface.
