如何在Unity中根据方向和方向将摄像头定位在玩家后面

using UnityEngine;

public class CameraController : MonoBehaviour
{
    public Transform player; // 玩家对象
    public float distance = 5f; // 摄像头与玩家的距离
    public float height = 2f; // 摄像头与玩家的高度差
    public float rotationDamping = 3f; // 旋转阻尼

    private Vector3 offset; // 摄像头位置偏移量

    private void Start()
    {
        offset = new Vector3(0f, height, -distance);
    }

    private void LateUpdate()
    {
        if (player != null)
        {
            // 计算目标位置
            Vector3 targetPosition = player.position + player.TransformDirection(offset);

            // 平滑旋转
            Quaternion targetRotation = Quaternion.LookRotation(player.position - transform.position);
            transform.rotation = Quaternion.Slerp(transform.rotation, targetRotation, rotationDamping * Time.deltaTime);

            // 设置摄像头位置
            transform.position = targetPosition;
        }
    }
}
