AssetDatabase.GetAssetDependencyHash

切换到手册
public static Hash128 GetAssetDependencyHash (string path);
public static Hash128 GetAssetDependencyHash (GUID guid);

参数

path 资源的路径。
guid GUID of the asset.

返回

Hash128 聚合哈希值。

描述

返回资源所有依赖项的哈希值。

此哈希函数会聚合了以下内容：源资源路径、源资源、元文件、目标平台以及导入器版本。 如果此哈希值发送变化，则说明导入资源可能已更改，因此应重新构建相关的资源捆绑包。 

using UnityEditor;
using UnityEngine;

public class AssetDatabaseExamples : MonoBehaviour
{
    [MenuItem("AssetDatabase/Dependency Hash Example")]
    public static void DependencyHashExample()
    {
        //Load a Material, change its shader and save it
        var matPath = "Assets/Material.mat";
        var asset = (Material)AssetDatabase.LoadMainAssetAtPath(matPath);
        asset.shader = Shader.Find("Unlit/Texture");
        AssetDatabase.SaveAssets();

        //Print out the hash into the console
        var hash = AssetDatabase.GetAssetDependencyHash(matPath);
        Debug.Log(hash);

        //Change the Shader on the Material and save it
        asset.shader = Shader.Find("Standard");
        AssetDatabase.SaveAssets();

        //Hash will be different
        hash = AssetDatabase.GetAssetDependencyHash(matPath);
        Debug.Log(hash);
    }
}
