Unity/Addressable/複数ロード

準備

1. Unityメインメニュー/Window/Asset Management/Addressables/Groupsを選択
2. ロードしたいオブジェクトのlabels部分にラベル名を追加(例："TestLabel")

サンプル

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

public class AssetLabelsLoadScene : MonoBehaviour
{
    [SerializeField]
    Button loadButton;
    [SerializeField]
    GameObject canvas;
    GameObject instance;
    void Start()
    {
        loadButton.onClick.AddListener(() => {
            if (instance == null)
            {
                StartCoroutine(Load());
            }
        });
    }
    IList<GameObject> list;
    IEnumerator Load()
    {
        var handle = Addressables.LoadAssetsAsync<GameObject>("TestLabel", null);
        yield return handle;
        if (handle.Status == AsyncOperationStatus.Succeeded)
        {
            list = handle.Result;
            foreach (var value in list)
            {
                Debug.Log(value.name);
            }
        }
    }
}
