Can anyone explain what the camera is doing?

Question

I'm creating a scene where I can grab parts for building a character and just as I finished how I want my camera set up I noticed something weird. The object I have grabbed when pulled towards the camera, splits in 2. Can anyone explain why its doing this or how to fix it?

Here is a GIF I made of it happening. https://gyazo.com/d8fa629b5555dbe36db607a55a3e888e

This script is on every object I want to move with the mouse

Here is the specific code that deals with camera movement by scrollwheel

 public Vector3 diff;
 public float distanceWanted;
     
 diff = Camera.main.transform.position - transform.position; 
 float curCameraDistance = Input.GetAxis("Mouse ScrollWheel");  
 transform.position = GetMouseWorldPos() + diff.normalized * distanceWanted;
 
 if (curCameraDistance < 0f)
         {
             distanceWanted++;
         }
 else if (curCameraDistance > 0f)
         {
             distanceWanted--;
         }

Hey guys so I ended up solving this... It seems I am too persistent. I just ended up redoing my code (4 different ways) and got to this point. Here's the code if you were interested. Just a reminder to anyone who uses this. This script is on each GameObject you want to move.

 //Set for base starting distance (Will be changed using scrollwheel)
 public float distanceWanted = 30f;
 
 //While the mouse is held down
     private void OnMouseDrag()
     {
         //For scrolling
         float curCameraDistance = Input.GetAxis("Mouse ScrollWheel");
 
         if (curCameraDistance > 0f)
         {
             distanceWanted++;
         }
         else if (curCameraDistance < 0f)
         {
             distanceWanted--;
         }
 
         Vector3 mousePosition = new Vector3(Input.mousePosition.x, Input.mousePosition.y, distanceWanted);
         Vector3 objPos = Camera.main.ScreenToWorldPoint(mousePosition);
 
         transform.position = objPos;    
     }

not 100% sure this is happening but it looks like you are going over "0" with your movement, effectively your block is trying to move from 1 to -1 each frame because you keep moving it 'towards' the camera and overshooting the 0 mark. u might want add some boundaries to your script to stop this from happening, have the movement stop when 'minDistance' is reached.

0 is the camera position (so this might not be 0,0,0) but explaining it with 1 , -1 and 0 will make most sense i think.

I tested that and the object was still about 10 unity units from the near plane of the camera when it happened. I think your on the right path though that it might somehow have been trying to move the object in between 2 points for some reason.

Can anyone explain what the camera is doing?
