有的时候，想把某些对象如预制体、音频、图片赋值到场景，不想每个资源都写一个变量，用list又没法将不同的类型的对象放在一个数组里，同时想使用这些资源跟使用Resources下的资源一样。那么接来下这个工具，就满足了这些需求。
第一步，创建场景资源脚本对象文件如图
Paste_Image.png
Paste_Image.png
Paste_Image.png
第二步，将相应资源拖到面板即可，可拖单独文件，也可拖文件夹
Paste_Image.png
到此资源就创建好了
第三步，创建场景资源管理

将之前创建的资源脚本对象赋值到此处
第四步，获取资源
假设想获取的是某个音频则代码如下
SceneResources.Instance.Load<AudioClip>("xxxx");
这边有个注意点，就是假设，音频文件和其他文件（如图片）命名一样，获取的时候就可以加上相应的后缀,就能获取指定对象了。
SceneResources.Instance.Load<AudioClip>("xxxx.mp3");
在如果，音频文件，有两个同名，但是，在不同的文件夹下，这时候要获取指定的，就可以通过路径去获取了

资源其实可以直接赋值到场景中，只是这样要修改资源的时候，都要打开场景，所以这里单独创建了一个资源脚本对象去管理资源。这样后续的修改就方便多了，每个场景对应一个资源脚本对象。
接下来看看代码是如何实现的。
资源脚本对象类
using System.Collections.Generic;
using UnityEngine;
namespace WZK
{
[CreateAssetMenu(fileName = "场景资源", menuName = "创建场景序列化资源")]
public class ResourcesScriptableObject : ScriptableObject
{
public List<Config> _objectList = new List<Config>();
public List<string> _choseExtensionList = new List<string>();//扩展名
public int _showMin = 1;
public int _showMax = 10000;
[System.Serializable]
public class Config
{
public Object _object;//物体
public string _assetPath;//Asset下路径
public Config(Object obj = null, string assetPath = "")
{
_object = obj;
_assetPath = assetPath;
}
}
}
}
