Unity development - scene asynchronous loading

Set up

scene A-> scene C, But the scene C Resources are too big , Jump scene will appear when loading jump directly C There was a Caton when I was , So when the scene is loaded , Make a scene B（ Black screen effect ） The transition of , Not too embarrassing for Caton , So you need to implement the scenario A-> scene B-> scene C.

1、 Select the scene interface

among ButtonState Script ButtonState.cs

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

public class ButtonState : MonoBehaviour
{
    [SerializeField]
    private float localScale;
    [SerializeField]
    private float PointScale;
    public void OnPointerEnter(PointerEventData eventData)// When the mouse enters UI Events executed after execution  
    {
        transform.localScale = new Vector3(PointScale, PointScale, PointScale);
    }
    public void OnPointerExit(PointerEventData eventData)// When the mouse goes away UI Events executed after execution  
    {
        transform.localScale = new Vector3(localScale, localScale, localScale);
    }
    public void OnDisable()
    {
        transform.localScale = new Vector3(localScale, localScale, localScale);
    }
}

Two 、GameObject The script hanging above ：GameController.cs

 

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

public class GameController : MonoBehaviour
{
    public static List<LanguageScence> dic;
   
    //public AudioSource AudioEffect;
    public GameObject AudioBg;

    public static int M;
    private static bool Isplay = false;
    private GameObject go;

  
    private void Awake()
    {
        if (!Isplay)
        {
            go = Instantiate(AudioBg);// Play background music 

        }
    }
    // After choosing the language , Set variable value , Change the scene 
    public void SelectLanguage(string name)
    {
        switch (name)
        {
            case "Chinese":
                M = 1;
                SceneLoad();
                break;
            case "English":
                M = 2;
               SceneLoad();
                break;
            case "Finnish":
                M = 3;
                SceneLoad();
                break;
        }
    }
    // Scene conversion 
    void SceneLoad()
    {
        if (!Isplay)
        {
            DontDestroyOnLoad(go);
            Isplay = true;
        }
        Debug.Log(" Go to the black ball scene first ");
        SceneManager.LoadScene("loadScene");
    }
}

3、 ... and 、 Scripts that need to be supported

①LanguageScence.cs

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

public class LanguageScence : MonoBehaviour
{
    public List<string> ELanguageText = new List<string>();
}

②LanguageState.cs

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

//public class LanguageState : MonoBehaviour
//{
//}
public enum LanguageState//2 change class by enum Enumerated values 
{

    Chinese,
    English,
    Finnish
}

Four 、 Three jump scenes

5、 ... and 、 Dark scenes ：loadScene

Dark scene script ：

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

public class AsnyScene : MonoBehaviour
{
    AsyncOperation async = null;
    void Awake()
    {
        StartCoroutine(asynEvent(GameController.M));// Loading scenarios asynchronously 
    }
    void Update()
    {
    }
    IEnumerator asynEvent(int level)
    {
        Debug.Log(" The black curtain of the transition appears ");
        yield return null;
        AsyncOperation asyncOperation = SceneManager.LoadSceneAsync(level);// The scene is not superimposed 
        asyncOperation.allowSceneActivation = true;// Whether to allow jump after loading 
        
    }
}

6、 ... and 、 summary

scene A-> scene B-> scene C when , Because the scene B（ Dark scenes ） For scenes with small resources , So you can jump directly , It can be loaded directly , But the scene B-> scene C when , scene C There are many resource files , Cause slow loading , Therefore, asynchronous loading is adopted in the dark scene , therefore , scene A-> scene B（ Dark scenes ） Use in ：

SceneManager.LoadScene(" Black scene name or index ");

Can , And in the scene B-> scene C when , Convert black scenes to scenes C when , Using asynchronous loading ：

AsyncOperation asyncOperation = SceneManager.LoadSceneAsync(“ Scene name or scene index ”);// The scene is not superimposed 
        asyncOperation.allowSceneActivation = true;// Whether to allow jump after loading 

That is, when the scene is not loaded C when , Stay in the scene B in , In a dark scene , Solve the embarrassment of loading .
