Addressable是可尋址資源，是一種通過地址加載資產的方法，能夠簡化內容包創建、部署。和更新。一旦資產被標記爲可尋址，就可以從任何地方調用可尋址資源，可以通過AssetReference加載單個可尋址資源，也可以通過自定義組標籤加載多個可尋址資產。

操作教程

安裝addressable
將prefab標記爲可尋址對象
簡化名稱
打標籤組
Play Mode Script選擇Use Existing Build(require built groups)
Profiles
Build

載入代碼

var operateHandler = Addressables.LoadAssetsAsync<GameObject>(Label, OnLoadComplete);

完整代碼：

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

public class CharacterManager : MonoBehaviour
{
    public string Label="default";
    public Transform LoadingPanelTrans;
    LoadingPanel loadingPanel;
    bool m_AssetsReady = false;
    public Transform ButtonPanelTrans;
    public Dictionary<string, Button> btnDic;
    public Dictionary<string, GameObject> objDic;
    public Transform spawnParent;
    private void Awake()
    {
        btnDic = new Dictionary<string, Button>();
        objDic = new Dictionary<string, GameObject>();
        for (int i=0;i< ButtonPanelTrans.childCount; i++)
        {
            Transform child = ButtonPanelTrans.GetChild(i);
            if (!btnDic.ContainsKey(child.name))
            {
                Button btn = child.GetComponent<Button>();
                btnDic.Add(child.name, btn);
                btn.onClick.AddListener(() => { SpawnCharacter(btn.name); });
                btn.interactable = false;
            }
        }
    }
    // Start is called before the first frame update
    IEnumerator Start()
    {
        if(LoadingPanelTrans!=null)
            loadingPanel = new LoadingPanel(LoadingPanelTrans);
        var operateHandler = Addressables.LoadAssetsAsync<GameObject>(Label, OnLoadComplete);//通過label載入
        operateHandler.Completed += LoadAddressables_Completed;
        while (!operateHandler.IsDone)
        {
            loadingPanel.ShowProgress(operateHandler.PercentComplete);//顯示進度條
            Debug.Log(operateHandler.PercentComplete);//此處爲載入進度
            yield return null;
        }
        yield return null;
    }

    private void OnLoadComplete(GameObject obj)
    {
        if(!objDic.ContainsKey(obj.name))
        objDic.Add(obj.name, obj);
        if(btnDic.ContainsKey(obj.name))
            btnDic[obj.name].interactable = true;
    }

    private void LoadAddressables_Completed(AsyncOperationHandle<IList<GameObject>> obj)
    {
        loadingPanel.Hide();//隱藏loading界面
    }

    public void SpawnCharacter(string characterName) {
        Debug.Log(characterName);
        Vector3 position = Random.insideUnitSphere * 5;
        position.Set(position.x, 0, position.z);
        if (objDic.ContainsKey(characterName))
            Instantiate<GameObject>(objDic[characterName],position,Quaternion.identity,spawnParent);
    }
    private void OnDestroy()
    {
		btnDic.clear();
		objDic.clear();
    }
}

用這種方式載入通過operateHander.PercentComplete可以獲取下載進度，還有另一種載入的方式:

using System.Collections.Generic;
using UnityEngine;
using UnityEngine.AddressableAssets; //TODO: Mention the use of this namespace
using UnityEngine.ResourceManagement.AsyncOperations; // TODO: Mention that this is needed to do the async operations over the lists?

public class CharacterManager : MonoBehaviour
{
    public GameObject m_archerObject;

    public AssetReference m_ArcherObject;

    public List<AssetReference> m_Characters;
    bool m_AssetsReady = false;
    int m_ToLoadCount;
    int m_CharacterIndex = 0;

    Start is called before the first frame update
    void Start()
    {
        m_ToLoadCount = m_Characters.Count;

        foreach (var character in m_Characters)
        {
           character.LoadAssetAsync<GameObject>().Completed += OnCharacterAssetLoaded;
        }
    }


    public void SpawnCharacter(int characterType)
    {
        Instantiate(m_archerObject);

        m_ArcherObject.InstantiateAsync();

        if (m_AssetsReady)
        {
           Vector3 position = Random.insideUnitSphere * 5;
           position.Set(position.x, 0, position.z);
           m_Characters[characterType].InstantiateAsync(position, Quaternion.identity);
        }
    }

    void OnCharacterAssetLoaded(AsyncOperationHandle<GameObject> obj)
    {
       m_ToLoadCount--;

       if (m_ToLoadCount <= 0)
           m_AssetsReady = true;
    }

    private void OnDestroy() //TODO: Should we teach instantiate with game objects and then manually release?
    {
       foreach (var character in m_Characters)
       {
           character.ReleaseAsset();
       }
    }
}

這種方式也可以載入資源，但是打出apk會顯示獲取進度一直卡在50%（進度顯示有問題，但是不影響下載）

打完包後的路徑位於ServerData對應打包的平臺目錄下。本例是這個目錄:ServerData\Android
將ServerData目錄底下的文件上傳服務器即可，本例服務器路徑如下:

自己配置遠程服務器需要修改Profiles中對應遠程服務器的地址，重新打包並上傳自己的服務器
更新資源：
會彈出一個讓你選的框
打包apk
