53. Unfocusable Area Focusable Collider
54. Hit Detection public boolean hitDetection(...) { RaycastHit hitInfo; Vector3 start = transform.position; start.z = -3; Vector3 end = transform.position; end.z = 3; if (Physics.Linecast(start, end, out hitInfo)) { return hitInfo.collider == collider; } return false; }
