我如何限制Y轴上的旋转，使玩家不能在Unity中连续旋转相机

using UnityEngine;

public class CameraRotation : MonoBehaviour
{
    public float rotationSpeed = 1.0f;
    public float minYRotation = -90.0f;
    public float maxYRotation = 90.0f;

    private void Update()
    {
        float mouseX = Input.GetAxis("Mouse X");
        float mouseY = Input.GetAxis("Mouse Y");

        float rotationX = mouseX * rotationSpeed;
        float rotationY = mouseY * rotationSpeed;

        transform.Rotate(Vector3.up, rotationX);

        float currentYRotation = transform.rotation.eulerAngles.x;
        float newYRotation = currentYRotation - rotationY;

        newYRotation = Mathf.Clamp(newYRotation, minYRotation, maxYRotation);

        transform.rotation = Quaternion.Euler(newYRotation, transform.rotation.eulerAngles.y, transform.rotation.eulerAngles.z);
    }
}
