Move camera when mouse is near the edges of the screen

Question

  void MoveCam()
     {
         Vector3 camPos = transform.position;
         if (Input.mousePosition.x > screenWidth - 30)
         {
             isCamMoving = true;
             camPos.x += speed * Time.deltaTime;
         }
         else if (Input.mousePosition.x < 30)
         {
             isCamMoving = true;
             camPos.x -= speed*Time.deltaTime;
         }
         
         else if (Input.mousePosition.y > screenHeight - 30)
         {
             isCamMoving = true;
             camPos.z += speed*Time.deltaTime;
         }
         else if (Input.mousePosition.y < 30)
         {
             isCamMoving = true;
             camPos.z -= speed * Time.deltaTime;
         }
         else
         {
             isCamMoving = false;
         }
     }

why isn't t$$anonymous$$s code working? I'm a noob btw. I have t$$anonymous$$s in the update, I tried commenting out every other part of my camera scripts except t$$anonymous$$s part and it still wasn't working. What's wrong with it?

You never assign the new position to your transform :

  transform.position = camPos ;

camPos is assigned to transform.position on line 3, it should make the trick.

No, because Vector3 are structs, not instances of classes

Whazt do you mean? What should I assign it to then?

Changing camPos does not change transform.position (Vector3 are value types, not reference types). Thus, at the end of the function, after you change the values of your camPos vector, you must assign this new vector to the real transform.position of your camera.

   void MoveCam()
  {
      Vector3 camPos = transform.position;

      // Make change to camPos;

      transform.position = camPos ;
  }
