这篇博客详细介绍了在Unity中如何使用UnityEngine.SceneManagement进行场景的异步加载，并通过UI Slider和Text组件实时显示加载进度。代码示例展示了如何在Login和Main两个场景间平滑切换，并通过限制场景激活来防止加载过程中的不必要操作。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;
using UnityEngine.UI;
 public enum Scenetype
   {
   Login,//开始场景
    Main//战斗场景
   }
 public class UILoadingView : MonoBehaviour
 {
public static Scenetype scentype;

public Slider slider;
public Text text;
private AsyncOperation async;


void Start ()
{
    if (scentype == Scenetype.Main)
    {
        async = SceneManager.LoadSceneAsync("Main");
    }
    else if (scentype == Scenetype.Login)
    {
        async = SceneManager.LoadSceneAsync("Login");
    }
    //异步跳转       
   // async = SceneManager.LoadSceneAsync(JianJie.Instance.Path_ );           
    async.allowSceneActivation = false;
   
}
private int progpress;
private int currprogpress;
void Update ()
{
    OnTime();
}
public void OnTime()
{
    if (async != null)
    {
        if (async.progress < 0.9)//跳转加载进度
        {
            //使加载不生硬 
            progpress = Mathf.Clamp((int)async.progress * 100, 1, 100);
        }
        else
        {
            progpress = 100;
        }
        if (currprogpress < progpress)
        {
            currprogpress++;
            slider.value = currprogpress / 100.0f;
            text.text = string.Format("{0}%", currprogpress );
        }
        else
        {
            slider.value = 1;
            currprogpress = 100;    
            text.text = string.Format("{0}%", currprogpress);
            async.allowSceneActivation = true;
        }
    }
}
}
