Hash128 集合ハッシュ

説明

アセットのすべての依存関係のハッシュを返します

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/DependencyHashExample")]
    public static void DependencyHashExample()
    {
        //Load a Material, change it's 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);
    }
