[U3D]资源加载的解决方案-Addressables(可寻址资产系统)

之前大家使用热更的时候都使用的是unity3d自带的assetbundle(AB)包,但是说实话对于使用来说还是存在着非常大的问题的

1. 打包需要通过写代码
2. 依赖关系,比较麻烦
   现在有一个特别好的东西可以解决unity之前AB包的一个问题

正常步骤

1. 资源设置为addressable

2. 设置资源对应的路径

3. 设置生成和加载的路径

   

4. 设置运行模式

   

5. 把我们标记为address的生成出来.

   

6. 加载这个资源

   using UnityEngine;
   using UnityEngine.AddressableAssets;
   
   public class samplesuse : MonoBehaviour
   {
       // Start is called before the first frame update
       void Start()
       {
           LoadAE();
       }
   
       public void LoadAE()
       {
           Addressables.LoadAssetAsync<GameObject>("Assets/Cube.prefab").Completed += LoadCubeCompleted;
       }
   
       private void LoadCubeCompleted(UnityEngine.ResourceManagement.AsyncOperations.AsyncOperationHandle<GameObject> obj)
       {
           Addressables.InstantiateAsync("Assets/Cube.prefab");
           Instantiate(obj.Result);
       }
   }
   

四个样本

Addressables Utility

加载引用资源

Disable AssetImport on Build

build不允许使用引入资源

Import Groups Tool

引入资源

Prefab Spawner

预制体孵化器,可以直接孵化addressable的预制体,并且可以调整生成时间,存活时间,等参数.

热更例子

是否可以跨项目加载

可以加载gameobject,但是脚本无法加载

代码

using UnityEngine;
using UnityEngine.AddressableAssets;

public class loadotherae : MonoBehaviour
{
    // Start is called before the first frame update
    void Start()
    {
        string url = @"E:\WorkStations\Unity\addressenble\Library\com.unity.addressables\aa\Windows\catalog.json";
        Addressables.LoadContentCatalogAsync(url).Completed += (arg) =>
        {
            Addressables.LoadAssetAsync<GameObject>("Assets/Cube.prefab").Completed += LoadCubeCompleted;
        };
    }

    private void LoadCubeCompleted(UnityEngine.ResourceManagement.AsyncOperations.AsyncOperationHandle<GameObject> obj)
    {
        Addressables.InstantiateAsync("Assets/Cube.prefab");
        Instantiate(obj.Result);
    }
}
