RaycastHit hit; /* (Vector3) hit.point - the point where the ray has collided. (Quaternion) hit.normal - the normal of the GameObject the ray has collided. (float) hit.distance - the distance between the ray origin and hit.point. (Transform) hit.transform - the transform of the GameObject the ray has hit (Rigidbody) hit.rigidbody - rigidbody attached to GameObject ray collided, if no rigidbody is attached, value is null. (Vector2) hit.textureCoord - the coordinate of the point on the texture of the GameObject the ray collided. */
