常用功能------物体跟随摄像机视角y轴旋转

1、直接上代码，挂载到物体上即可

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

/// <summary>
/// 限制旋转，只让跟着摄像机y轴旋转
/// </summary>
public class LookAtCam : MonoBehaviour
{
    
    
    private Transform m_camTrans;

    void Start()
    {
    
    
        m_camTrans = Camera.main.transform;
    }

    void Update()
    {
    
    
        Vector3 v = m_camTrans.position;
        v.y = transform.position.y;
        this.transform.LookAt(v);
    }
}
