Get a raycast to hit only child objects to use axes

I have walls, floors, and ceilings of a level grouped under the name of Map5 which I have tagged Level. I have also made a rotation script that with the intention of rotating the whole level around the player. I want to use the walls axes for my rotation, which should have a sort of hinge effect.I have tagged the walls based on the direction they are facing (for example; left walls are tagged as Left) The problem I have is that the any wall the ray hits is counted as Level since they are all children of Map5. I need my ray to hit the children so I can use their axes but I don't know how. Please help?

Here is my current code If it helps at all...

var Player : Transform; var rotateAmount = 90; var controller : CharacterController; var Hit : RaycastHit;

function FixedUpdate () {
//casts a ray from camera to point in world // If the controller is grounded and the ray hits an object; then you can Rotate walls if (controller.isGrounded) canRotate =true;
if(Input.GetMouseButtonDown(0)){ var ray = Camera.main.ScreenPointToRay (Input.mousePosition); if (Physics.Raycast (ray, Hit, 50)){ var Hitobject : GameObject = Hit.transform.gameObject; var pivot : Transform = Hitobject.transform; Debug.Log("hit"+ gameObject.name); if((Input.GetMouseButtonDown(0)) && (Hitobject.gameObject.tag == "Left")){ RotateObject(Player.position,pivot.forward, 90,1); } } } }
