| dependency | Name of dependency. You can use any name you like, but because these names are global across all your Assets, it can be useful to use a naming convention (eg a path-based naming system as in the example below) to avoid clashes with other custom dependency names. |
Allows you to specify that an Asset has a custom dependency.
Use custom dependency if need to setup a dependency to something that can't be expressed as either an source asset dependency or artifact dependency.
using UnityEngine; using UnityEditor.Experimental.AssetImporters; using UnityEditor.Experimental; using UnityEngine.Assertions; using UnityEditor;
class MySystem { public const string CustomDependencyName = "MyProject/Settings";
public static string GetSetting() { return "42"; }
public static void RegisterCustomDependency() { // You cannot register a custom dependency during the Asset Import process, so this method must be called before the Asset is imported. AssetDatabaseExperimental.RegisterCustomDependency(CustomDependencyName, Hash128.Compute(GetSetting())); } }
class SomeValue : ScriptableObject { public int value; }
[ScriptedImporter(1, "data", AllowCaching = true)] public class MyDataImporter : ScriptedImporter { public override void OnImportAsset(AssetImportContext ctx) { ctx.DependsOnCustomDependency(MySystem.CustomDependencyName);
var someObj = ScriptableObject.CreateInstance<SomeValue>();
var setting = MySystem.GetSetting(); if (setting == "42") someObj.value = 100; else someObj.value = -1;
ctx.AddObjectToAsset("someObj", someObj); } }
