Rotating Problem!

Hello all,
I tried to do that if i moving the mouse it will move the object to the mouse place but it works bad in the rotating it seems like i rotating around the GameObject and not the GameObject rotating with me!
Here is an example:
--> this video from 3:06 mins!

And here is how it works for me:

Here the Codes:

Code (CSharp):

1.         if (Input.GetKeyDown(KeyCode.E))
2.         {
3.             Ray ray = Camera.main.ScreenPointToRay(new Vector3(Screen.width / 2, Screen.height / 2, 0.0f));// creating ray to the middle of the screen.
4.             RaycastHit hit;
5.  
6.             if(Physics.Raycast(ray, out hit, 500.0f))
7.             {
8.                 if(IsPlacing == false)//Cant place another one while placing!
9.                 {
10.                     IsPlacing = true;
11.                     PlacingObject = Instantiate(Resources.Load("Objects/Foundation"), new Vector3(hit.point.x, hit.point.y +2, hit.point.z), Quaternion.Euler(0, Camera.main.transform.rotation.y, 0)) as GameObject;
12.                     PlacingMaterial = Resources.Load("Materials/AblePlacement", typeof(Material)) as Material;
13.                     PlacingObject.GetComponent<Renderer>().material = PlacingMaterial;
14.                     //PlacingObject = null;//Sets the things only on the last object, and then deleting the variable!
15.                 }
16.                 else if(IsPlacing == true)
17.                 {
18.                     Debug.Log ("Finish placing to countinue!");
19.                 }
20.  
21.             }
22.         }
23.         if (IsPlacing == true)
24.         {
25.             Vector3 MousePosition = new Vector3(Input.mousePosition.x, Input.mousePosition.y, Distance);
26.             Vector3 PlacingObjectPosition = Camera.main.ScreenToWorldPoint(MousePosition);
27.             PlacingObject.transform.position = PlacingObjectPosition;
28.             PlacingObject.transform.position = Vector3.Lerp (PlacingObject.transform.position, PlacingObject.transform.position, Smoothy);
29.             PlacingObject.transform.Rotate(0, Input.GetAxis("Mouse ScrollWheel") * CrusorSpeed, 0);
30.         }

How can i fix this problem and make it the same as the first video?
Thanks all for help!

 

Can you please try to debug PlacingObject after line 29 ?

Are you sure that you are using Vector3.Lerp correctly?

 

I can delete it, i checked it and it doesnt help me, the main problem is with the rotation i want to do that if the rotation saved it doesnt metter where i will move the GameObject it will show me the rotation degress in the game because it looks like i am rotating around the object and not the object rotates with me...

 

And why are you placing Input.GetAxis("Mouse ScrollWheel") * CrusorSpeed on Y ? do you want it to rotate Up or right/left ?

 

I wanna rotate it right and left..

 

I made some searching try this out:

replace

Input.GetAxis("Mouse ScrollWheel") * CrusorSpeed

with

Input.GetAxis("Mouse Y") * CrusorSpeed

Please tell me if it worked.

 

It is not working good bro.

 

That's strange , really.. what are you getting now?

 

When i`m moving the mouse up and down it rotates the object.

 

Try this:

replace this
Input.GetAxis("Mouse Y") * CrusorSpeed

with this

Input.GetAxis("Mouse X") * CrusorSpeed

 

It rotates the object not in the way i want it to rotate.
