unity 场景跳转初步优化——异步跳转_unity有很多场景需要频繁跳转怎么优化

一个滑动条，一个按钮

新建脚本async.cs

using UnityEngine;
using System.Collections;
using UnityEngine.SceneManagement;//命名空间场景跳转
using UnityEngine.UI;
 
public class async : MonoBehaviour
{
 
    AsyncOperation asy; //协程的变量
    public Slider slider;
    float value = 0;//滑动条的值
    void Start()
    {
 
    }
    public  void OnClick()
    {
      
            StartCoroutine(LoadScene());
 
    }
 
    // Update is called once per frame
    void Update()
    {
        if (asy == null)
        {
            return;
        }
        int jd = 0;
        if (asy.progress < 0.9f)
        {
            jd = (int)asy.progress * 100;
 
        }
        else
        {
            jd = 100;
        }
        if (value < jd)
        {
            value++;
 
        }
        slider.value = value / 100;
        if (value == 100)
        {
            asy.allowSceneActivation = true;
        }
 
    }
    IEnumerator LoadScene()
    {
        asy = SceneManager.LoadSceneAsync(1);
        asy.allowSceneActivation = false;
        yield return asy;
    }
}
