Method RaycastClosest

RaycastClosest(Vector3, Vector3, QueryFilter?)

Casts a ray and returns the nearest shape it hits.

public RaycastHit RaycastClosest(Vector3 origin, Vector3 translation, QueryFilter? filter = null)

origin Vector3: The start of the ray, in world space.
translation Vector3: The ray vector. Its length is the range.
filter QueryFilter?: Which shapes the ray may hit, or null for everything.

RaycastHit: The nearest hit. Check Box3D.RaycastHit.Hit before reading anything else.

var hit = world.RaycastClosest(muzzle, aim * 100.0f);
if (hit.Hit)
{
    Spawn(Impact, hit.Point, hit.Normal);
}

Ignores shapes the ray starts inside. Allocates nothing and needs no callback, so this is the one to reach for unless you need custom filtering.
