Why doesnt my Y axis update?

Question

So, I'm trying to make my object's y-axis match my camera's y-axis, and for some reason the Rotation component doesn't change when my camera changes.

My VERY SIMPLIFIED code:

 public class MovementControllerWalking : MonoBehaviour
 {
 
     // Camera Entities
     public GameObject cameraObject;
     public Quaternion cameraRot;
 
     // Player Entities
     
     
     void Update()
     {
         cameraRot = cameraObject.transform.rotation;
         GetComponent<Transform>().rotation = new Quaternion(0.0f, cameraRot.y, 0.0f, 0.0f);
     }
 }

You can't get rotation by using Quaternion's Y. Quaternions are a lot more complex than that.

Use eulerAngles (Or localEulerAngles if camera is parented under an object)

    public Transform mainCam;
 
     private Vector3 cameraRot;
 
     private void Update()
     {
         cameraRot = mainCam.eulerAngles;
 
         transform.rotation = Quaternion.Euler(0f, cameraRot.y, 0f);
     }
