How can I make my 2D camera and world rotate around its y-axis?

I have built a basic 2D endless runner game where you run on platforms, jump and double jump.

What I want to do is to make it so I run in circles along the y axis, to avoid getting an out of bounds issue if I ever reach the float number boundary.

To ensure this runs correctly, I would need all objects in the world to keep the same rotation, including the camera.

This however, presents an issue for me as I'm not sure how to solve it.

I have tried adding the following 2 scripts to the MainScene Scene Object I have, but none of them works, either only the player rotates or the whole world rotates but the camera doesn't and the player falls down because of the rotation.

Script 1:

Code (csharp):

1.  
2.     public Transform target;
3.  
4.     // Update is called once per frame
5.     void Update () {
6.         transform.rotation = Quaternion.Euler(transform.rotation.x, target.transform.rotation.y, transform.rotation.z); //lock y-rotation on target
7.     }
8.  

Script 2:

Code (csharp):

1.  
2.     void FixedUpdate () {
3.         if (playerScript.playerIsMoving)
4.         {
5.             //rotate to keep within float boundaries of the world, but only if the player is moving.
6.             transform.Rotate(transform.rotation.x, transform.rotation.y + 0.1f, transform.rotation.z);
7.         }
8.     }
9.  

Any ideas?

Thank you for reading this and your help.

 

Ok, I've made the world and camera rotate with this code.

Code (csharp):

1.  
2.             if (playerScript.playerIsMoving)
3.             {
4.                 //rotate to keep within float boundaries of the world, but only if the player is moving.
5.                 Quaternion camPosition = transform.rotation;
6.                 camPosition.eulerAngles = Vector3.Lerp(camPosition.eulerAngles, new Vector3(camPosition.eulerAngles.x, camPosition.eulerAngles.y + 0.1f, camPosition.eulerAngles.z), Time.deltaTime);
7.                 transform.rotation = camPosition;
8.             }
9.  

This however, does not seem to work as intended.

What happens is this.

Here's what it normally looks like.


Here's when I only rotated the scene.


Here's when I rotated the camera AND the scene.

Why doesn't this work?

 

As far as I can gather, the issue comes down to sprites by default only being visible from 1 side.

 

I've stopped working on this issue for now, as I believe this requires a 3d world and not a 2d.

So i'll just live with potentially having the float boundary issue, unless someone knows a solution to that.
