## Addressable Load

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

public class Test : MonoBehaviour
{
    //bundle資源的label
    public AssetLabelReference characterLabel;
    public IList<GameObject> characters;
    // Start is called before the first frame update
    void Start()
    {
        //LoadCubeAssetAsync();
        //StartCoroutine(LoadCubeAsset());


        Addressables.LoadAssetsAsync<GameObject>(characterLabel, null).Completed += OnLoadDone;
    }

    private void OnLoadDone(AsyncOperationHandle<IList<GameObject>> obj)
    {
        Debug.Log("加載資源完成");
        Debug.Log(obj);
        Debug.Log("獲得加載資源：");
        Debug.Log(obj.Result);
        // In a production environment, you should add exception handling to catch scenarios such as a null result;
        if (obj.GetType() != null)
        {
            characters = obj.Result;
            Instantiate(characters[0]);
        }
    }

    private async void LoadCubeAssetAsync()
    {
        var cube = Addressables.LoadAssetAsync<GameObject>("Assets/Bear.prefab");
        await cube.Task;
        Instantiate(cube.Result);
    }

    private IEnumerator LoadCubeAsset()
    {
        var cube = Addressables.LoadAssetAsync<GameObject>("Assets/Bear.prefab");
        yield return cube;
        Instantiate(cube.Result);
    }
}
