raycast object instance offset?

Question

Lads,

I'm using raycast and mousedown to swap one gameobject for another. All is working, but the instantiated object comes in offset (I'd like it to come in the exact position of the gameobject it's replacing). I think the problem has to do with the hit.point of the ray or the destruction of the gameObject... not sure. Anyway, here's the code:

 function Update () {
 
     var hit : RaycastHit;
         if(Physics.Raycast (transform.position,
                         transform.forward, hit, 500)) {
         if (hit.collider.gameObject.tag=="Block" 
         && Input.GetMouseButtonDown(0) == true) {
         var forward : Vector3 = transform.TransformDirection(Vector3.forward) * 500;
         Debug.DrawRay (transform.position, forward, Color.green);
         
             //var instance2:GameObject = Instantiate (Resources.Load
             //("Detonator_explosion1"),transform.position, transform.rotation);
             var instance:GameObject = Instantiate (Resources.Load
             ("building_stage_2_test"),hit.point, Quaternion.identity);
             Destroy (hit.collider.gameObject);    
     
         }
    }
   }

Any thoughts?...

ps - the pivot locations of the object being instanced and the object being destroyed match.

Thx,

Stef

Well, you're instancing it at the exact hit.point position. Use hit.transform.position instead, which is the pivot of the object that was hit.

I changed the hit.point to:

var instance:GameObject = Instantiate (Resources.Load ("building_stage_2_test"),hit.transform.position, hit.transform.rotation);

but am still getting the same result?...

Hm, the only explanation I can think of is that the objects really have a different pivot. If you drag both the original object and your "building_stage_2_test" into the Hierarchy view (so that they have identical values in their transform), are the really placed on top of each other, the way you want them to?

Or you actually hit a different object, interfering with it. Is the original object composed of multiple GameObjects/colliders/sub-objects?
