【Unity】Addressables资源管理笔记

Addressables是一种用于管理资源的系统。允许以一种灵活的方式加载、卸载和管理资源，无论是场景、预制件、材质、纹理、音频剪辑等。

一、快速实现

1. 安装Addressables插件
   

2. 把对象添加到组

   1）打开AddressablesGroups面板

   window→AssetManagement→Addressables→Grounps

   2）建立环境预制体到组

   打包预制体后直接拖拽到默认的组(Default Local Group)下

   

   这里可以看见预制体自动添加了一个寻址路径，拿到这个路径就可以动态加载该资源

   

3. 加载对象

   简单的资源加载

       void Update()
       {
           if (Input.GetKeyDown(KeyCode.C))
           {
               AddAsset();
           }
       }
       void AddAsset()
       {
            Addressables.LoadAssetAsync("Assets/Prefab/Environment_Prefab.prefab").Completed +=
               (asyncOperationHandle) =>
               {
                   if (asyncOperationHandle.Status == AsyncOperationStatus.Succeeded)
                   {
                       Instantiate(asyncOperationHandle.Result);
                   }
                   else
                   {
                       Debug.Log("加载失败");
                   }
               };
       }
   

二、加载方法

1. 根据路径加载

    void AddAsset()
       {
           asyncOperationHandle = Addressables.LoadAssetAsync<GameObject>("Assets/Prefab/Environment_Prefab.prefab");
           asyncOperationHandle.Completed += AsyncOperationHandle_Completed;
       }
       void AsyncOperationHandle_Completed(AsyncOperationHandle<GameObject> asyncOperationHandle)
       {
           if (asyncOperationHandle.Status == AsyncOperationStatus.Succeeded)
           {
               Instantiate(asyncOperationHandle.Result);
           }
           else
           {
             Debug.Log("加载失败");
           }
       }
   

2. 根据标签加载

       [SerializeField] AssetLabelReference labelReference;
       void AddAssetForAssetLabelReference()
       {
           Addressables.LoadAssetAsync(labelReference).Completed +=
               (asyncOperationHandle) =>
               {
                   if (asyncOperationHandle.Status == AsyncOperationStatus.Succeeded)
                   {
                       Instantiate(asyncOperationHandle.Result);
                   }
                   else
                   {
                       Debug.Log("加载失败");
                   }
               };
       }
   

3. 指定预制体加载

    [SerializeField] AssetReference assetReference;
    void AddAssetForAssetReference()
       {
           assetReference.LoadAssetAsync().Completed+=
                   (asyncOperationHandle) =>
                   {
                       if (asyncOperationHandle.Status == AsyncOperationStatus.Succeeded)
                       {
                           game= asyncOperationHandle.Result;
                           Instantiate(game);
                       }
                       else
                       {
                           Debug.Log("加载失败");
                       }
                   };
         
       }
   

4. 加载多个资源

       void AddAssetForAssetLabelReferences()
       {
           Addressables.LoadAssetsAsync(labelReference, (addAesst) => { Instantiate(addAesst); })
               .Completed +=
               (asyncOperationHandle) =>
               {
                   if (asyncOperationHandle.Status == AsyncOperationStatus.Succeeded)
                   {
                       Debug.Log("加载成功");
                   }
                   else
                   {
                       Debug.Log("加载失败");
                   }
               };
       }
   

5. 加载创建与卸载

      
   GameObject game;
       void AddAssetForAssetInstantiateAsync()
       {
             assetReference.InstantiateAsync().Completed += (asyncOperation) => game = asyncOperation.Result;
       }
       void ClearInstantiateAsset()
       {
           //该方法只适用于InstantiateAsync创建的资源
           assetReference.ReleaseInstance(game);
           GC.Collect();
       }
   

6. 远程加载

   1）开启远程

   window→AssetManagement→Addressables→Setting

   勾选BuildRemoteCatalog

   Build&Load Paths 选择Remote

   

选择资源组Addressables Asset Grounp

Build&Load Paths 选择Remote

2）修改配置文件

window→AssetManagement→Addressables→Profiles

Remote.BuildPath是创建路径

Remote.LoadPath是远程地址

[BuildTarget]是发布是类型文件夹，比如webgl和StandaloneWindows64

这里可以创建多个配置文件

3）发布

发布后可以在对应的文件夹下找到资源文件

网发布文件的时候，需要将整个文件夹一起拷贝到地址下

这里可以从配置文件中看到

配置文件地址通常在StreamingAssets→aa下

包括：settings.json和catalog.json

最后建议还是使用AssetBundle，自己写配置和依赖
