Unity中摄像机平滑跟随主角移动

摄像机跟随主角移动
主要用的的知识点是线性插值与圆形插入

using UnityEngine;
class FollowingPlayer
{
    private Transform playerTrans;

    public float speed;

    void Start()

    {
            playerTrans=GameObject.FindWithTag("Player").transform;

    }
    void Update(()

    {

        //移动线性插值

        Vector3 targetPos=playerTrans.potition+new Vector3(0,2.4f,-2.4f);

        this.transform.position=Vector3.Slerp(this.transform.position,targetPos,speed*Time.deltaTime);

        //角度圆形插值

        Quaternion targetRotation=Quaternion.LookRotation(playerTrans.position-targetPos);

        this.transform.rotation=Quaternion.Slerp(this.transform.rotation,targetRotation,speed*Time.deltaTime);

    }

}
