Unity Addressables学习笔记—汇总

正文

1.创建一个新场景

我是创建在Resources/Scenes目录下，如图：
在这里插入图片描述

2.为场景创建一个Addressables的Group

Game1Group就是我新创建的一个Group用来存放场景1的所有资源，分组的配置跟Remote一样，都是远程的，加载地址是我本地启动的web服务器地址，URL里WebGL那个目录也不是必须的，根据自己实际的来。
在这里插入图片描述

3.把新场景和场景里用到的资源全部拖入到Game1Group里

上边的图就是拖完的状态。

4.在初始化的场景里添加代码，用Addressables的方式加载新的场景Game1.

我是在最开始的场景里图片1那个开始按钮上加了个点击事件去触发加载Game1这个场景的

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.AddressableAssets;
using UnityEngine.ResourceManagement.AsyncOperations;
using UnityEngine.UI;

public class GameController : MonoBehaviour
{
    private Sprite sprite;
    public Button btn;
    public List<string> list;
    void Start()
    {
        //Addressables.Instantiate("Play Button").Result.transform.position = new Vector3(2f, 2f);
        foreach (string name in list)
        {
            Addressables.LoadAssetAsync<GameObject>(name).Completed += SpriteLoadedObj;
        }
        //PlayerPrefs.DeleteKey(Addressables.kAddressablesRuntimeDataPath);
        Addressables.LoadAssetAsync<Sprite>("Play Button Img").Completed += SpriteLoaded;
    }



    private void SpriteLoaded(AsyncOperationHandle<Sprite> obj)
    {
        switch (obj.Status)
        {
            case AsyncOperationStatus.Succeeded:
                sprite = obj.Result;
                Debug.Log(sprite);
                btn.image.sprite = sprite;
                break;
            case AsyncOperationStatus.Failed:
                Debug.LogError("Sprite load failed.");
                break;
            default:
                //case AsyncOperationStatus.None:
                break;
        }
    }

    private void SpriteLoadedObj(AsyncOperationHandle<GameObject> obj)
    {
        switch (obj.Status)
        {
            case AsyncOperationStatus.Succeeded:
                GameObject a = Instantiate(obj.Result);
                a.transform.position = new Vector2(2f, 2f);
                break;
            case AsyncOperationStatus.Failed:
                Debug.LogError("Sprite load failed.");
                break;
            default:
                //case AsyncOperationStatus.None:
                break;
        }
    }


    // Update is called once per frame
    void Update()
    {

    }
    public void onClick()
    {
        Addressables.LoadSceneAsync("Game1");
    }
}

5.场景1：用Addressables创建一个对象,在Hierarchy里拖进去一个对象，一共2个对象

下边是场景1拖进去的一个对象
在这里插入图片描述
下边是GameObject上随便绑定一个C#脚本再去创建一个对象

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.AddressableAssets;
using UnityEngine.ResourceManagement.AsyncOperations;

public class Game1Controller : MonoBehaviour
{
    // Start is called before the first frame update
    void Start()
    {
        Addressables.LoadAssetAsync<GameObject>("Layer 10").Completed += SpriteLoadedObj;
    }

    // Update is called once per frame
    private void SpriteLoadedObj(AsyncOperationHandle<GameObject> obj)
    {
        switch (obj.Status)
        {
            case AsyncOperationStatus.Succeeded:
                GameObject a = Instantiate(obj.Result);
                a.transform.position = new Vector2(2f, 2f);
                break;
            case AsyncOperationStatus.Failed:
                Debug.LogError("Sprite load failed.");
                break;
            default:
                //case AsyncOperationStatus.None:
                break;
        }
    }
}
