Declaration

public static Hash128 GetAssetDependencyHash(GUID guid);

Parameters

path Path to the asset.
guid GUID of the asset.

Returns

Hash128 Aggregate hash.

Returns the hash of all the dependencies of an asset.

The hash aggregates the following: source asset path, source asset, meta file, target platform and importer version. The change of this hash indicates that the imported asset may have changed so the relevant asset bundles should be rebuilt.

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); } }
