unity中简单的时间回溯功能_unity 怎么更好的做事件流 及事件回溯

先创建要回溯的信息类

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
 
public class TimeRecord 
{
    public Vector3 postion;
    public Quaternion rotation;
 
    public TimeRecord(Vector3 postion, Quaternion rotation)
    {
        this.postion = postion;
        this.rotation = rotation;
    }
}

回溯时间

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
 
public class TimeRollback : MonoBehaviour
{
    public float speed;
    public float RecordTime;
 
    bool isRollBack;
    List<TimeRecord> timeRecordList;
 
    private void Start()
    {
        timeRecordList = new List<TimeRecord>();
    }
 
 
    private void Update()
    {
        if (Input.GetKeyDown(KeyCode.Space))
        {
            isRollBack=true;
        }
 
    }
    private void FixedUpdate()
    {
        if (isRollBack)
        {
            RollBackTimeInformation();
        }
        else
        {
            RecordTimeInformation();
            transform.position += Vector3.right * speed * Time.fixedDeltaTime;
        }
    }
    //记录信息
    public void RecordTimeInformation()
    {
        //Mathf.Round用于对浮点数进行四舍五入。
        if (timeRecordList.Count >Mathf.Round( RecordTime/Time.deltaTime))
        {
            //移除最后一个元素
            timeRecordList.RemoveAt(timeRecordList.Count-1);
        }
        timeRecordList.Insert(0, new TimeRecord(transform.position, transform.rotation));
    }
    //回溯时间
    public void RollBackTimeInformation()
    {
        if(timeRecordList.Count>0)
        {
            transform.position = timeRecordList[0].postion;
            transform.rotation = timeRecordList[0].rotation;
            //移除下标为零的元素
            timeRecordList.RemoveAt(0);
        }
        else
        {
            isRollBack = false;
        }
    }
 
}
