unity中加载下一个场景且不销毁当前场景的方法

using System.Collections;

1using System.Collections.Generic;
2using UnityEngine;
3using UnityEngine.UI;
4using UnityEngine.SceneManagement;
5
6public class TEST : MonoBehaviour {
7
8    public Button btn;
9
10    public void Start()
11    {
12        btn.onClick.AddListener(() => Load());
13    }
14
15    public void Load()
16    {
17        AsyncOperation  ass=SceneManager.LoadSceneAsync("02",LoadSceneMode.Additive);
18    }
19
20
21}

代码比较简单 主要是了解

1SceneManager.LoadSceneAsync（异步加载）的参数含义：《1》public static AsyncOperation LoadSceneAsync(int sceneBuildIndex, LoadSceneMode mode);　　　　int  sceneBuildIndex：是在scenes in build中场景的下标（一般不建议使用该方法）　　　  LoadSceneMode mode：LoadScenesMode 是个枚举 有两种　　　　
2
3// 摘要: 
4    //     Used when loading a scene in a player.
5    public enum LoadSceneMode
6    {
7        // 摘要: 
8        //     Closes all current loaded scenes and loads a scene.
9        Single = 0,
10        //
11        // 摘要: 
12        //     Adds the scene to the current loaded scenes.
13        Additive = 1,
14    }

  　　 single:关闭所有当前加载的场景并加载场景。
　　　Additive :将场景添加到当前加载的场景中
