【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();}
