Unity3D如何在激活辅助摄像头时让角色面向辅助摄像头的方向

using UnityEngine;

public class CharacterController : MonoBehaviour
{
    public Camera auxiliaryCamera;

    private void Update()
    {
        if (auxiliaryCamera != null)
        {
            Vector3 targetDirection = auxiliaryCamera.transform.position - transform.position;
            targetDirection.y = 0; // 如果不想角色在垂直方向上旋转，可以将y轴设为0
            transform.rotation = Quaternion.LookRotation(targetDirection);
        }
    }
}
