Unity：Time类中常用的变量解释_unity 用什么变量存储time.time

在看过Siki老师的“Unity API常用方法和类详细讲解”的视频。
对Time类基础的用法有了自己的看法。
以下为Time类中常用的变量的使用。

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

public class APITimeFunction : MonoBehaviour
{
    private void Start()
    {
        Debug.Log("Time.deltaTime: " + Time.deltaTime);
        Debug.Log("Time.fixedDeltaTime: " + Time.fixedDeltaTime);
        Debug.Log("Time.fixedTime: " + Time.fixedTime);
        Debug.Log("Time.frameCount: " + Time.frameCount);
        Debug.Log("Time.realtimeSinceStartup: " + Time.realtimeSinceStartup);
        Debug.Log("Time.smoothDeltaTime: " + Time.smoothDeltaTime);
        Debug.Log("Time.time: " + Time.time);
        Debug.Log("Time.timeScale: " + Time.timeScale);
        Debug.Log("Time.timeSinceLevelLoad: " + Time.timeSinceLevelLoad);
        Debug.Log("Time.unscaledTime: " + Time.unscaledTime);
    }

    private void FixedUpdate()
    {
        Debug.Log("Time.fixedDeltaTime: " + Time.fixedDeltaTime);
        Debug.Log("Time.fixedTime: " + Time.fixedTime);
        Debug.Log("Time.time: " + Time.time);
        Debug.Log("Time.deltaTime: " + Time.deltaTime);
    }

    void Update()
    {
        //每一帧运行的秒数
        Debug.Log("Time.deltaTime: "+Time.deltaTime);
        //每一帧固定运行的秒数，可以通过改变此帧数来改变FixUpdate的运行次数
        Debug.Log("Time.fixedDeltaTime: " + Time.fixedDeltaTime);
        //每一帧固定的运行时间,在FixedUpdate中和Time完全相同
        Debug.Log("Time.fixedTime: " + Time.fixedTime);
        //游戏运行的总帧数
        Debug.Log("Time.frameCount: " + Time.frameCount);
        游戏开始运行的总时间
        Debug.Log("Time.realtimeSinceStartup: " + Time.realtimeSinceStartup);
        平滑达到Time.deltaTime
        Debug.Log("Time.smoothDeltaTime: " + Time.smoothDeltaTime);
        //这一帧开始的时间，受到暂停控制
        Debug.Log("Time.time: " + Time.time);
       // 时间流逝（0，1，2），控制时间的流逝
        Debug.Log("Time.timeScale: " + Time.timeScale);
        //此场景的加载所消耗的时间
       Debug.Log("Time.timeSinceLevelLoad: " + Time.timeSinceLevelLoad);
        //正常TimeScale下的Time
        Debug.Log("Time.unscaledTime: " + Time.unscaledTime);
    }
}
