Definition

public CollectImportedDependenciesAttribute(Type importerType, uint version)

Parameters

importerType

The type of the importer for which the getter is called by the AssetDatabase.

version

The version of the imported dependencies getter.

Remarks

It is recommended to always increment the version number of the callback whenever the script is changed. This forces assets imported with lower version numbers to be re-imported.
This example shows how you can declare a dependency between two prefabs imported by the ModelImporter and use them in an AssetPostprocessor.
using UnityEditor;using UnityEditor.AssetImporters;using UnityEngine;public class ProceduralParentPostprocessor : AssetPostprocessor{ private const string s_DependentPath = "Assets/ProceduralPrefab.fbx"; private const string s_DependencyPath = "Assets/DependencyPrefab.fbx"; [CollectImportedDependencies(typeof(ModelImporter), 1)] public static string[] CollectImportedDependenciesForModelImporter(string assetPath) { if (assetPath.Equals(s_DependentPath)) return new[] { s_DependencyPath }; return null; } void OnPostprocessMeshHierarchy(GameObject root) { if (root.name == "ProceduralPrefabRoot") { // Add a new child game object var go = AssetDatabase.LoadMainAssetAtPath(s_DependencyPath) as GameObject; Object.Instantiate(go, root.transform, true); } }}
Note: The attribute supports only native importer types with AssetPostprocessor callbacks: ModelImporter, TextureImporter, AudioImporter, and SpeedTreeImporter.
