【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

安装Addressables插件
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

加载对象

简单的资源加载

    void Update()
    {
        if (Input.GetKeyDown(KeyCode.C))
        {
            AddAsset();
        }
    }
    void AddAsset()
    {
         Addressables.LoadAssetAsync<GameObject>("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

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");
        }
    }

根据标签加载

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

指定预制体加载

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

加载多个资源

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

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();
    }
