unity设置帧率

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

public class Run : MonoBehaviour
{
    // Start is called before the first frame update
    void Start()
    {
        Debug.Log("hello unity");

        Application.targetFrameRate = 100;

    }

    // Update is called once per frame
    void Update()
    {
        Debug.Log(Time.time);
        print("---------------------------");
        Debug.Log(Time.deltaTime);


    }
}

Time.time当前时间

Time.deltaTime固定的与上一帧的时间

 Application.targetFrameRate = 100;设置运行的帧率一秒运行多少次

Time.deltaTime 约等于1/ Application.targetFrameRate 不是完全按时设定的来，是尽量接近。
