    Code (CSharp):
    1. private int pointIndex;
    2.         private PathCreator pathCreator;
    3.  
    4.         private void OnMouseDrag()
    5.         {
    6.             if (pathCreator != null)
    7.             {
    8.                 var rayMoving = Camera.main.ScreenPointToRay(Input.mousePosition);
    9.                 Physics.Raycast(rayMoving, out var hitMoving);
    10.                 transform.position = hitMoving.transform.position;
    11.                 pathCreator.bezierPath.MovePoint(pointIndex, hitMoving.transform.position);
    12.                 pathCreator.gameObject.GetComponent<RoadMeshCreator>().CreatePath();
    13.                 Debug.Log("Position to: " + hitMoving.transform.position);
    14.             }
    15.         }
    Why should be this?

    The return value of Raycast is bool. If it returns
    false
    , no hit was detected and everything in the
    out
    parameter is reset to default values (not left unwritten which some might expect). Usually people say
    if (Raycast...)
    and only proceed if the ray hit. I expect you're never detecting a hit due to layer or collider issues.
